[0023] The water inlet end of the laser light source 300 is connected to a cold water inlet pipe 203, and the water outlet end is connected to a hot water drain pipe 207; the water inlet end of the digital micromirror 400 is connected to a cold water inlet pipe 2, and the water outlet end is connected to a hot water drain pipe 206; wherein, the cold water inlet pipe 203 and the cold water inlet pipe 2 are connected to a cold water source at one end away from the laser light source 300 and the digital micromirror 400, and the hot water drain pipe 1 207 and the hot water drain pipe 2 206 are connected to a hot water collection mechanism at one end away from the laser light source 300 and the digital micromirror 400.

[0024] Furthermore, the cold water inlet pipe 2 includes a section pipe 1 204 and a section pipe 2 205, one end of the section pipe 1 204 is connected to a cold water source, one end of the section pipe 2 205 is connected to one end of the digital micromirror 400, and a cold exhaust fan 500 placed in the closed shell 100 is connected between the other ends of the section pipe 1 204 and the section pipe 2 205; a plurality of groups of heat dissipation fins are provided in the shell of the cold exhaust fan 500, and cold water enters the shell and transfers heat through the fins, causing the fan to blow out cold air, thereby reducing the temperature in the closed shell 100, and the projector working system in the closed shell 100 can be cooled as a whole, with good heat dissipation effect.

[0025] See also Figure 3 The cold water source includes a water chiller 200, a cold water pipe 201 and a cold water tee 202; wherein the water chiller 200 is located outside the closed shell 100, one end of the cold water pipe 201 is connected to the cold water output end of the water chiller 200, and the other end is connected to the cold water tee 202, the end of the cold water inlet pipe 1 203 away from the laser light source 300 and the end of the section pipe 205 away from the cold exhaust fan 500 are both connected to the cold water tee 202, and the cold water tee 202 is installed in the closed shell The hot water collecting mechanism includes a water chiller 200, a hot water pipe 209 and a hot water tee 208; wherein, one end of the hot water pipe 209 is connected to the hot water input end of the water chiller 200, and the other end is connected to the hot water tee 208; the end of the hot water drain pipe 1 207 away from the laser light source 300 and the end of the hot water drain pipe 2 206 away from the digital micromirror 400 are both connected to the hot water tee 208, and the hot water tee 208 is also installed on the side wall of the closed shell 100.

The other path enters the cold exhaust fan 500 through the section pipe 1 204, so that the cold exhaust fan 500 blows out cold air, thereby reducing the temperature of the gas circulation inside the closed shell 100. After the cold water flows out from the cold exhaust fan 500, it enters the cold exhaust fan 500 through the section pipe 205. The digital micromirror 400 is water-cooled, and after the water-cooling heat exchange, the water temperature rises and turns into hot water, and the hot water flows out from the hot water drain pipe 2 206; the hot water in the hot water drain pipe 1 207 and the hot water in the hot water drain pipe 2 206 are collected through the hot water tee 208 and enter the hot water pipe 209 together, and then enter the water chiller 200 for cooling, and after cooling, it turns into cold water and continues to flow out from the cold water pipe 201 for recycling, thereby realizing the entire cyclic heat dissipation process; in this process, the projector working system inside the closed shell 100 will not come into contact with the outside air, thereby avoiding the contamination of dirt and dust, and having a good dust-proof effect.
