A Projector Heat Dissipation Structure and Projector
Technical Field
The present utility model relates to the field of projector
technology, particularly to a projector heat dissipation
structure and a projector.
Background Technology
A projector is a digital device capable of optically
projecting electronic data or images onto a screen. With the
advancement of technology, projectors are increasingly
applied in daily work and life. For instance, many teaching
venues
install
projectors
to
facilitate
instructional
activities. During operation, the electronic components
within projectors generate heat, necessitating effective
thermal management for each component. Existing projectors
typically employ fans (such as centrifugal fans) to create
cooling airflow paths, thereby enhancing heat dissipation
efficiency. However, the airflow from the blower outlet is
primarily directed along a centrifugal path (downward),
resulting in overly concentrated airflow. This leads to uneven
heat dissipation across some electronic components-such as
uneven cooling between the upper and lower sections of the
display screen. Areas with low cooling efficiency are prone
to screen burn-in or blackout phenomena. Therefore, a novel
projector heat dissipation structure and projector are
proposed.
Subject Matter of the Utility Model
The objective of this utility model is to provide a projector
heat dissipation structure and a projector to address the
aforementioned issues.
To achieve this objective, the utility model employs the
following technical solution:
A projector heat dissipation structure comprises:
An optical engine housing, wherein a first partition plate is
disposed within the cavity of said optical engine housing;
An optical assembly mounted within the optical engine housing,
comprising a light source, a display screen, and a lens
arranged sequentially downstream of the light source's optical
path;
A first heat dissipation assembly including a first fan
positioned within the cavity of the optical engine housing;
wherein: the first partition is positioned downstream of
the first fan's airflow path to direct the fan's airflow toward
the display screen; a first air guide block is mounted on one
side of the first partition, with the side facing the first
fan forming an inclined surface to redirect part of the fan's
airflow; an air duct is formed between the first air guide block
and the first partition. Optionally, the optical assembly further
comprises a reflector cup, with the light source positioned at the light
inlet of the reflector cup. A first Fresnel lens is arranged on one side of
the light-expanding port of the reflector cup. A heat-insulating glass is
positioned between the first Fresnel lens and the display screen. A second
Fresnel lens is arranged on the side of the display screen opposite the
heat-insulating glass.
Optionally, the optical housing comprises a first cavity and a second
cavity. The first fan, the first partition, and the first air guide block are all
disposed within the first cavity. The first Fresnel lens and the display
form a first air duct connecting the first cavity and the second cavity.
wherein the display screen and the second Fresnel lens form a second air
duct connecting the first cavity and the second cavity.
Optionally, the first cavity is provided with a first heat sink, with a
second fan positioned on one side of the first heat sink, wherein the
second fan is located outside the first cavity.
Optionally, the second cavity includes a third fan, a second partition
plate, and a deflector plate. One end of the second partition plate connects
to the display screen, while the other end connects to the third fan. The
deflector plate is positioned downstream of the third fan's airflow path to
guide the airflow from the third fan to both sides of the insulating glass.
Optionally, both sides of the diverter plate are provided with a
second air guide block. The side of the second air guide block facing the
third fan is inclined to alter the direction of part of the airflow from the
third fan. Air passages are formed between the second air guide block and
the second partition plate, as well as between the second air guide block
and the inner wall of the second chamber.
The inclination angle range of the inclined surfaces of the first and
second air guide blocks is between 35° and 75°.
Optionally, the projector cooling structure further comprises a
second cooling assembly. The second cooling assembly includes a second
heat sink mounted on the light source lamp holder, with a fourth fan
positioned on each side of the second heat sink.
Optionally, the optical engine housing comprises a base and a cover.
The present utility model also provides a projector comprising the
aforementioned projector cooling structure.Compared with the prior
art, the present utility model has the following beneficial
effects: When the projector is operating, light generated by
the light source is projected onto an external screen through
the display panel and lens. Simultaneously, heat generated by
the light source and heat produced during the operation of
electronic components cause the temperature of the electronic
components themselves to rise, i.e., the temperature of the
display panel increases. During projector operation, the first
fan is activated synchronously, with airflow from its outlet
primarily directed along a centrifugal path (downward). Due to
the air duct between the first air guide block and the first
partition, when the airflow generated by the first fan passes
through the first air guide block, part of the airflow flows
along this duct (without changing direction), while part of the
airflow is guided upward by the first air guide block. This
ensures that the airflow generated by the first fan passes
uniformly across the entire surface of the display screen when
it flows over it. In existing projector cooling structures, the
airflow from the cooling fan's outlet primarily flows in a
centrifugal
direction
(downward).
This
causes
the
air
generated by the cooling fan to mainly pass over the lower
surface of the display screen, resulting in low cooling
efficiency on the upper surface of the display screen. Compared
to
existing
projector
cooling
structures,
the
cooling
structure disclosed in this utility model utilizes the design
of the first air guide block to redirect a portion of the airflow
toward the upper surface of the display screen. This ensures
more uniform airflow distribution across the display screen,
effectively enhancing overall cooling efficiency, reducing
display screen failure rates, and extending the service life
of the projector.

or may involve components positioned centrally between them.
The technical solution of the present utility model is
further illustrated below with reference to the accompanying
drawings and through specific embodiments.
Referring to Figures 1 through 7, an embodiment of the
present utility model provides a projector comprising a
projector heat dissipation structure. The projector heat
dissipation structure includes an optical engine housing 10,
an optical assembly 20, and a first heat dissipation component
30. A first partition plate 11 is disposed within the cavity
of the optical engine housing 10. The optical assembly 20 is
mounted within the optical engine housing 10. The optical
assembly 20 comprises a light source 21, a display screen 22,
and a lens 23 arranged sequentially downstream of the light
source 21 in the optical path. The first heat dissipation
component 30 includes a first fan 31 positioned within the
cavity of the optical engine housing 10. The first partition
11 is located downstream of the airflow path of the first fan
31 to direct the airflow from the first fan 31 toward the display
screen 22. Simultaneously, the first partition 11 separates the
intake air path from the exhaust air path of the first fan 31,
meaning the intake port of the first fan 31 is located on one
side of the first partition 11, while the exhaust port of the
first fan 31 is located on the other side of the first partition
11. A first air guide block 32 is provided on one side of the
first partition 11. The first air guide block 32 and the outlet
of the first fan 31 are located on the same side of the first
partition 11. The side of the first air guide block 32 adjacent
to the outlet of the first fan 31 is inclined to alter the
direction of a portion of the airflow from the first fan 31.
An air passage exists between the first air guide block 32 and
the first partition 11. When air generated by the first fan 31
passes through the first air guide block 32, a portion of the
air flows upward under the guidance of the first air guide block
32, while another portion flows along the air channel (without
changing direction, i.e., downward). This ensures the airflow
generated by the first fan 31 is evenly distributed across the
entire surface of the display screen 22, effectively enhancing
the overall heat dissipation efficiency of the display screen
22, reducing its failure rate, and extending the service life
of the projector.Furthermore, the optical assembly 20 also
includes a reflector cup 24, with the light source 21 positioned
at the light inlet of the reflector cup 24. A first Fresnel lens
25 is mounted on one side of the light-expanding port of the
reflector cup 24. a heat-insulating glass 26 is positioned
between the first Fresnel lens 25 and the display screen 22,
and a second Fresnel lens 27 is arranged on the side of the
display screen 22 facing away from the heat-insulating glass
26. That is, the optical path of the light source 21
sequentially passes through the reflector cup 24, the first
Fresnel lens 25, the heat-insulating glass 26, the display
screen 22, and the second Fresnel lens 27. In this embodiment
of the utility model, the reflector cup 24 is housed within the
reflector cup sleeve. The light source 21's lamp base, the inner
wall of the reflector cup 24, the inner wall of the optical
engine housing 10's cavity, and the lens 23 collectively form
a sealed optical path cavity. The light source 21's lamp body,
the first Fresnel lens 25, the heat-insulating glass 26,
display screen 22, and second Fresnel lens 27 are all positioned
within the sealed optical path cavity. This prevents dust from
entering the optical system and affecting light transmission,
thereby effectively enhancing the performance of the optical
system and image quality.Furthermore, the optical housing 10
comprises a first cavity and a second cavity, both situated
within a sealed optical path cavity. The first fan 31, the first
partition 11, and the first air guide block 32 are all
positioned within the first cavity. The first Fresnel lens 25
and the display screen 22 form a first air passage connecting
the first and second cavities. The display screen 22 and the
second Fresnel lens 27 form a second air passage connecting the
first and second cavities. This arrangement enables air
generated by the first fan 31 to flow sequentially through the
first cavity, the first air passage, the second cavity, and the
second air channel, then returns to the first cavity through
the first air channel. This creates an internal circulation
airflow within the sealed optical cavity, thereby dissipating
heat from the optical assembly 20.
Furthermore, a first heat sink 33 is mounted on the first
cavity. The first heat sink 33 comprises a substrate and first
heat sink fins positioned on both sides of the substrate. The
substrate is connected to the side wall of the optical housing
10, meaning the substrate forms part of the sealed optical path
cavity's side wall. One side of the first heat sink 33's fins
is located within the sealed optical path cavity, while the
other side is positioned outside the sealed optical path cavity.
This arrangement enables the first heat sink 33 to dissipate
heat from the sealed optical path cavity to the external
environment. A second fan 34 is mounted on one side of the first
heat sink 33, positioned on the side of the first heat sink fin
located outside the sealed optical cavity. That is, the second
fan 34 is situated outside the first cavity to enhance the heat
dissipation efficiency of the first heat sink 33. It should be
noted that in the embodiments of the present utility model, the
first Fresnel lens 25, the heat-insulating glass 26, the
display screen 22, and the second Fresnel lens 27 are all
mounted within the cavity of the optical engine housing 10 via
a mounting frame (not shown). Consequently, the first air duct
and the second air duct are not directly connected, meaning that
air from the second air duct can only enter the first air duct
after passing through the second cavity.
Furthermore, the second chamber houses a third fan 35, a
second partition 36, and a baffle plate 37. The second partition
36 separates the intake air path from the exhaust air path of
the second fan 34, meaning the intake inlet of the second fan
34 is located on one side of the second partition 36, while its
exhaust outlet is positioned on the opposite side. Specifically,
one end of the second partition 36 connects to the display
screen 22, while the other end connects to the third fan 35.
This arrangement positions the intake of the second fan 34
downstream of the exhaust airflow path from the first fan 31.
The deflector plate 37 is positioned downstream of the exhaust
airflow path from the third fan 35 to guide the airflow from
the third fan 35 to both sides of the insulating glass 26.
Furthermore, both sides of the deflector plate 37 are
equipped with second air guide blocks 38. The side of the second
air guide block 38 facing the third fan 35 is inclined to alter
the direction of part of the airflow from the third fan 35. Air
passages exist between the second air guide block 38 and the
second partition 36, as well as between the second air guide
block 38 and the inner wall of the second cavity. It should be
noted that both the first fan 31 and the second fan 34 are
blowers, with air discharged from the blower outlets primarily
flowing in a centrifugal direction (downward). The principle
by which the second air guide block 38 directs the air generated
by the third fan 35 to flow upward is identical to that of the
first air guide block 32 and is not repeated here. The optical
housing 10 of the present utility model embodiment comprises
a base 12 and a cover 13, with both the first air guide block
32 and the second air guide block 38 mounted on the base 12.
Optionally, the inclination angle range of the inclined
surfaces of the first air guide block 32 and the second air guide
block 38 is between 35° and 75°.
Furthermore, the projector's heat dissipation structure
also includes a second heat dissipation assembly 40. The second
heat dissipation assembly 40 comprises a second heat sink 41
mounted on the light source 21's lamp holder, with a fourth fan
42 positioned on each side of the second heat sink 41. The second
heat sink 41 comprises a base, a heat pipe extending through
the base, and second heat dissipation fins positioned at both
ends of the heat pipe. The fourth fan 42 is mounted on one side
of the second heat dissipation fins. This design of the second
heat sink 41 effectively enhances the heat dissipation
efficiency of the light source 21 lamp holder.
The present utility model provides a cooling structure for
a projector, specifically implemented as follows: During
projector operation, light generated by light source 21 is
projected onto an external screen via display screen 22 and lens
23. Concurrently, heat generated by light source 21 and heat
produced
by
operating
electronic
components
cause
the
temperature of the electronic components themselves to rise,
i.e., the temperature of display screen 22 increases. The first
fan 31 is activated simultaneously with the projector's
operation. Airflow from the first fan's outlet primarily flows
in a centrifugal direction (downward). Due to the air passage
formed between the first air guide block 32 and the first
partition 11, when the airflow generated by the first fan 31
passes through the first air guide block 32, part of the airflow
flows along this passage (without changing direction), while
another part flows upward guided by the first air guide block
32. This arrangement ensures that the airflow generated by the
first fan 31 passes uniformly across the entire surface of the
display screen 22 when it flows over it. In existing projector
cooling structures, the airflow from the cooling fan outlet
primarily
blows
downward
in
a
centrifugal
direction.
Consequently, the airflow generated by the cooling fan mainly
passes over the lower surface of the display screen 22,
resulting in low cooling efficiency on the upper surface of the
display screen 22. Compared to existing projector cooling
structures, the cooling structure disclosed in this utility
model utilizes the design of the first air guide block 32 to
redirect part of the airflow toward the upper surface of the
display screen 22. This ensures more uniform airflow over the
display screen 22, effectively enhancing its overall cooling
efficiency, reducing the failure rate of the display screen 22,
and extending the service life of the projector.

and extending the service life of the projector.
The above embodiments are provided to illustrate the
technical solutions of the present utility model and are not
intended to limit it. Although the present utility model has
been described in detail with reference to the aforementioned
embodiments, those skilled in the art will understand that
modifications to the technical solutions described in the
embodiments or equivalent replacements of certain technical
features may still be made. Such modifications or replacements
