[0052] Figure 1-Figure 2 FIG. 2 shows a structural diagram of a heat dissipation structure 100 of a projector 200 according to an embodiment of the present application. Figure 1-Figure 2 As shown, the heat dissipation structure 100 may include:
[0053] Housing 110;
[0054] A glass assembly 120, wherein the glass assembly 120 is installed in the housing 110;
[0055] A display assembly 130, wherein the display assembly 130 is installed in the housing 110, and the display assembly 130 is located inside the glass assembly 120, and a first heat dissipation channel 121 and a second heat dissipation channel 122 are formed inside the glass assembly 120 through the display assembly 130, and the first heat dissipation channel 121 and the second heat dissipation channel 122 both have an air inlet end, and the air inlet ends of the first heat dissipation channel 121 and the second heat dissipation channel 122 are staggered;
[0056] A first heat dissipation component 140, wherein the first heat dissipation component 140 is installed in the housing 110, and the first heat dissipation component 140 delivers cold air into the first heat dissipation channel 121;
[0057] The second heat dissipation component 150 is installed in the housing 110 , and the second heat dissipation component 150 delivers cold air into the second heat dissipation channel 122 .
[0058] In this embodiment, cold air is blown into the first heat dissipation channel 121 and the second heat dissipation channel 122 through the first heat dissipation component 140 and the second heat dissipation component 150 respectively. The first heat dissipation channel 121 is located on one side of the display component 130, and the second heat dissipation channel 122 is located on the other side of the display component 130. The air inlet ends of the first heat dissipation channel 121 and the second heat dissipation channel 122 are staggered so that the cold air delivered by the first heat dissipation component 140 and the second heat dissipation component 150 are delivered to the two sides of the display component 130 in different directions, so that the two sides of the display component 130 are evenly cooled, thereby improving the heat dissipation effect of the device, ensuring timely and effective heat dissipation of the display component 130, and preventing a black screen caused by untimely and uneven heat dissipation;
[0059] By arranging the first heat dissipation channel 121 and the second heat dissipation channel 122 on both sides of the display component 130 respectively, and staggering the air inlet ends of the first heat dissipation channel 121 and the second heat dissipation channel 122, it is ensured that the airflows in the first heat dissipation channel 121 and the second heat dissipation channel 122 do not interfere with each other, so that the heat dissipation on both sides of the display component 130 is timely performed, avoiding the mutual influence of the airflows in the first heat dissipation channel 121 and the second heat dissipation channel 122, resulting in uneven heat dissipation and a black screen phenomenon.
[0060] It should be noted that the first heat dissipation channel 121 and the second heat dissipation channel 122 are not connected to each other, and the first heat dissipation component 140 and the second heat dissipation component 150 are used to evenly dissipate heat on both sides of the display component 130;
[0061] The display component 130 is a common LCD display screen on the market. When the projector 200 is in use, the LCD display screen is illuminated through a light funnel, so that the image is refracted by a refractor to the lamp bead for projection.
[0062] like Figure 1 As shown, in one embodiment,
[0063] The glass assembly 120 includes:
[0064] A Fresnel lens 123, wherein the Fresnel lens 123 is mounted on the housing 110, the Fresnel lens 123 and the display assembly 130 form a first heat dissipation channel 121, and the first heat dissipation assembly 140 is located at an air inlet end of the first heat dissipation channel 121;
[0065] Insulating glass 124, the insulating glass 124 is mounted on the housing 110, the insulating glass 124 and the display assembly 130 form a second heat dissipation channel 122, and the second heat dissipation assembly 150 is located at the air inlet end of the second heat dissipation channel 122;
[0066] A support block 125 is connected to a gas outlet pipe 126, and the gas outlet pipe 126 extends to the outside of the shell 110. The first heat dissipation channel 121 and the second heat dissipation channel 122 also have gas outlet ends. The support block 125 is located at the gas outlet end of the first heat dissipation channel 121. The first heat dissipation channel 121 is communicated with the gas outlet pipe 126 on the support block 125, and the gas outlet end of the second heat dissipation channel 122 is communicated with the cavity in the shell 110.
[0067] In this embodiment, the air inlet ends of the first heat dissipation channel 121 and the second heat dissipation channel 122 are arranged alternately, and the first heat dissipation channel 121 is formed by the Fresnel lens 123 and the display component 130. The first heat dissipation component 140 transports cold air into the first heat dissipation channel 121. The insulating glass 124 and the display component 130 form the second heat dissipation channel 122. The second heat dissipation component 150 transports cold air into the second heat dissipation channel 122. The cold air is transported to the first heat dissipation channel 121 and the second heat dissipation channel 122 from different directions through the first heat dissipation component 140 and the second heat dissipation component 150, respectively, to avoid convection of the airflow and affect the cooling of the display component 130. The airflow after heat dissipation in the first heat dissipation channel 121 is transported to the outside of the shell 110 through the outlet pipe 126, and the airflow after heat dissipation in the second heat dissipation channel 122 is discharged through the heat dissipation port 111 on the other side of the shell 110.

[0072] In this embodiment, the first mounting frame 141 has an air inlet and an air outlet, the air outlet corresponds to the air inlet end of the first heat dissipation channel 121, and the first heat dissipation fan 142 is installed at the air inlet. The first heat dissipation fan 142 transports the air at the air inlet to the first heat dissipation channel 121 through the air outlet. By only providing the air inlet and the air outlet on the first mounting frame 141, it is ensured that the cold air of the first heat dissipation fan 142 is only blown into the first heat dissipation channel 121 through the air outlet, thereby preventing the airflow from entering other spaces in the shell 110, thereby increasing the air flow rate in the first heat dissipation channel 121 and improving the heat dissipation efficiency.

[0074] The mounting plate 160 is obliquely mounted on the housing 110 . The mounting plate 160 is used to mount a refractor. The second heat dissipation assembly 150 is mounted on a side of the mounting plate 160 away from the refractor.

[0077] The second heat dissipation component 150 includes:
[0078] A second mounting frame 151, wherein the second mounting frame 151 is mounted on the mounting plate 160, and an upwardly inclined end of the mounting plate 160 corresponds to an air inlet end of the second heat dissipation channel 122;
[0079] The second heat dissipation fan 152 is installed on the second installation frame 151 .

[0082] like Figure 1 As shown, in one embodiment, it also includes:
[0083] The radiator 170 is installed on the housing 110 , and the radiator 170 is located at one side of the first mounting frame 141 .
[0084] The housing 110 has a heat dissipation opening 111 , and the heat dissipation opening 111 corresponds to the position of the heat sink 170 .
[0085] In this embodiment, the airflow outputted from the second heat dissipation channel 122 passes through the interior of the housing 110 , passes through the heat sink 170 , and is discharged to the outside of the housing 110 through the heat dissipation opening 111 .
