Heat management system of laser projector

Abstract

The invention discloses a heat management system of a laser projector. The system comprises a mainboard, and further comprises an altitude sensor, an external environment temperature sensor, a DMD cooling fan, a laser light source and a laser light source cooling fan which are connected with the mainboard, wherein the laser light source comprises a color wheel and a laser array; a color wheel temperature sensor connected with the mainboard is arranged in a position 1cm away from the disc surface of the color wheel; a laser temperature sensor connected with the mainboard is attached to the heat exchange surface of the laser array; and the laser array is connected with a laser water-cooling heat dissipation module. According to the system, a control system automatically adjusts and changes corresponding parameters at different external environment temperatures and altitudes; and the control system accurately adjusts the rotational speed of each corresponding fan in real time in combination with the parameters according to data detected and sent by each temperature detection sensor to finally realize automatic and effective heat dissipation.

Description

technical field [0001] The invention relates to the field of heat dissipation of a projector, in particular to a thermal management system of a laser projector. Background technique [0002] At present, projectors have been widely used in various fields. Since the projector dissipates a lot of heat during operation, it is necessary to design a cooling system to effectively ensure the reliable operation of the projector. The heat dissipation system of traditional projectors is manually set according to the environmental conditions used by customers, including ambient temperature and altitude, to achieve effective heat dissipation and keep the machine running within a safe temperature range. However, due to the wide variety of environments in various places around the world, this must put forward higher requirements for the use of the machine in pairs. Customers in different environments have to carefully consider the environmental parameters they are in, and then set up the ...

Problems solved by technology

However, due to the wide variety of environments in various places around the world, this must put forward higher requirements for the use of the machine in pairs. Customers in different environments have to carefully consider the environmental parameters they are in, and then set up the projector. There is a certain degree of randomness and uncontrollability in this process, which has great hidden dangers to the safe use of the projector.
