Embodiment Construction

[0013] In order to describe the structure, features and functions of the present invention in detail, a preferred embodiment is listed and described as follows in conjunction with the following drawings.

[0014] see Figure 2 to Figure 4 , the heat dissipation module 30 provided by a preferred embodiment of the present invention is disposed in the projector 20 to dissipate heat from the light source 22 of the projector 20 . The heat dissipation module 30 includes a heat dissipation base 40 and a blower fan 50 .

[0015] The heat sink 40 has a base body 41 , a guide ring 42 , and a filter 43 . The seat body 41 has a first side plate 44 and a second side plate 45, the first side plate 44 has an air inlet 441 and a first side hole 443, the second side plate 45 has an air outlet 451 and a second side hole 452, and is connected with The first side plates 44 are butted against each other, so that a heat dissipation air channel 46 is formed between the first side plate 44 and the ...

Abstract

The invention relates to a heat dissipation module of a projector, which mainly comprises a heat dissipation base and a blower fan arranged on the heat dissipation base. The heat dissipation base provided for the light source of a projector comprises an air inlet, a heat dissipation air channel communicated with the air inlet, a convolution air channel connected with the heat dissipation air channel, and an air outlet communicated with the heat dissipation air channel.

Description

technical field [0001] The invention relates to a projector, in particular to a heat dissipation module of the projector. Background technique [0002] see figure 1 The known projector 10 shown is mainly provided with an air inlet 11, an air outlet 12, and a cooling air duct 13 connecting the air inlet 11 and the air outlet 12. Two fans 15,16 on both sides. After the fan 15 sucks the outside air from the air inlet 11 into the heat dissipation duct 13, the cold air will flow through the light source 14 to provide heat dissipation, and then the hot air passing through the light source 14 will be discharged from the projector 10 through the fan 16 through the air outlet 12. . [0003] If the light source 14 bursts, the fragments of the light source 14 are easily affected by the two fans 15, 16 and scattered throughout the cooling air duct 13, resulting in inconvenient cleaning. Some fragments may even be ejected from the air outlet 12, so People located near the projector 1...
