Problems solved by technology

[0002] The projector is a precision equipment, using a high-pressure gas discharge lamp as the light source, the light source will generate a lot of heat when working, especially the large lumen projector generates more heat, it needs a lot of air for heat exchange to cool, so it is an open The air circulation system can only be used in a dry, clean, low temperature and good heat dissipation environment, and cannot work in a humid and closed environment, let alone work in water

Embodiment Construction

[0015] See figure 1 .

[0016] The projector that can be used for underwater work is that the projector is completely enclosed in a waterproof box shell 2 made of heat-conducting material, and the inside of the projector is provided with a liquid cooling device composed of a liquid conduction heat sink 4 and a fan 5, and a semiconductor The semiconductor refrigeration device composed of cooling fins 6 and fan 7 constitutes a closed cooling system, and the liquid cooling device and the semiconductor refrigeration device pass through the heat insulation board 3 and are connected to the box shell 2 .

[0017] The heat dissipation plate with grooves 8 and the heat dissipation plate with grooves 10 closely attached to the case shell 2 are arranged outside the box body shell 2 .

[0018] The heat dissipation plate with grooves 8 and the heat dissipation plate with grooves 10 are arranged on the front and rear sides of the box shell 2 respectively.

[0019] The liquid cooling devic...

Abstract

The invention discloses a projector capable of being used for underwater working. The whole projector is sealed in a waterproof box body shell made of heat conducting materials. A liquid cooling device and a semiconductor cooling device are arranged in the projector, a sealed type cooling system is formed, and the liquid cooling device and the semiconductor cooling device are both connected with the box body shell. The waterproof projector is of a sealed type structure, the sealed waterproof box body shell made of the heat conducting materials can guarantee the fact that the whole projector is tight without water leakage, moisture-resistant and dustproof effect is achieved, and heat in a box body can be conducted out of the box body shell. The liquid cooling device and the semiconductor cooling device are arranged in the projector to form the sealed type cooling system, and accordingly the problem of radiating cooling of a sealed structure is solved. The projector completely overcomes the shortcomings in the prior art and can be completely used for underwater working and be completely suitable for being used in various bad environments such as a wet sealed environment, an environment with a large amount of dust, a high-temperature environment and an environment with bad radiating.

Description

technical field [0001] The invention relates to projection equipment, in particular to a projector which can be used for underwater work. Background technique [0002] The projector is a precision equipment, using a high-pressure gas discharge lamp as the light source, the light source will generate a lot of heat when working, especially the large lumen projector generates more heat, it needs a lot of air for heat exchange to cool, so it is an open The air circulation system can only be used in a dry, clean, low temperature and good heat dissipation environment, and cannot work in a humid and closed environment, let alone work in water. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof projector which can be placed under water and has the functions of moistureproof and waterproof. [0004] In order to achieve the above object, the technical solution of the present invention is to completely seal the projector in a waterproo...
