Abstract

The invention relates to a refrigeration type liquid cooling heat dissipation closed LCD projection ray machine. The device comprises an internally-closed cavity, an out-of-cavity heat dissipation pipeline and a refrigeration sheet, an optical assembly, an in-cavity circulating fan and an in-cavity heat exchanger are arranged in the cavity, the optical assembly comprises an LCD, the in-cavity heat exchanger is arranged at an air outlet of the in-cavity circulating fan and comprises a first liquid outlet and a first liquid inlet, and the first liquid outlet is communicated with the first liquid inlet. The out-cavity heat dissipation pipeline comprises a second liquid inlet, a second liquid outlet, a pipeline heat exchange part and a water pump, the second liquid inlet is communicated with the first liquid outlet, the second liquid outlet is communicated with the first liquid inlet, and the pipeline heat exchange part is attached to the cold face of the refrigeration sheet. Compared with the prior art, by arranging the in-cavity circulating fan, the in-cavity heat exchanger, the out-cavity heat dissipation pipeline and the refrigeration sheet, a large amount of heat in the cavity can be discharged out of the cavity in time, so that the temperature of the optical assembly in the cavity is prevented from being too high, and the projection optical machine can meet high-power and high-brightness work.

Description

technical field [0001] The invention belongs to the technical field of LCD projection light machines, in particular to a closed LCD projection light machine of refrigeration type liquid cooling and heat dissipation. Background technique [0002] LCD projection light machine is a high-tech product combining liquid crystal technology, lighting technology and integrated circuits. Among them, the manufacture of liquid crystal panels and the photoelectric effect of liquid crystals are the core technologies of LCD projection light-mechanical imaging. At this stage, the LCD projection light machine in the industry is divided into semi-closed light machine and fully closed light machine. [0003] Semi-closed optical machine, the main feature is that the optical machine is equipped with air inlet and outlet, and the air inlet and air outlet are equipped with high-density dust-proof nets to prevent external dust from entering the interior, but because the optical machine is connected...
