Cooling system for wall-mounted projector

Abstract

The invention discloses a cooling system for a wall-mounted projector. The cooling system comprises a cooling channel which is arranged on one side of a host machine of the projector, the cooling channel is separated from the host machine of the projector provided with a plurality of heat sources through a first baffle, and the cooling channel is separated by a second baffle to form a plurality of mutually independent air channels. Each of the air channels is provided with an air inlet and an air outlet which is arranged opposite to the air inlet, wherein all air inlets are arranged below the corresponding air outlets so as to facilitate hot air to flow upwards. According to the cooling system for the wall-mounted projector, an independent air channel design is adopted, different heat sources are separated for independent cooling, and the cooling efficiency is improved.

Description

technical field [0001] The invention relates to heat dissipation technology, in particular to a heat dissipation system of a wall-mounted projector. Background technique [0002] As an emerging light source, light-emitting diodes (hereinafter referred to as LEDs) are becoming the darling of various application fields due to their small size, long life, energy saving and environmental protection. The luminance characteristics of LEDs change according to their temperature, so it is necessary to control the temperature below an appropriate level. If the temperature of the LED exceeds the specified temperature, the luminance will decrease and the life will also be significantly reduced. Therefore, the heat dissipation of the LED light source is the main problem that needs to be solved urgently at present. A good heat dissipation system will play a vital role in ensuring the long life of the LED. [0003] Conventionally, discharge lamps have been widely used as light sources fo...

Problems solved by technology

[0008] However, the above-mentioned heat dissipation system or device in the prior art does not take special consideration of the above situation, resulting in waste of energy and reduction of heat dissipation efficiency in LED light source projectors using the above heat dissipation system or device

Especially in existing projectors, the same heat dissipation method and heat dissipation efficiency are adopted for green LEDs, red LEDs and blue LEDs, so that the heat generated by relatively high power green LEDs and red LEDs cannot be achieved. Dissipate it in time; while the heat dissipation efficiency of the relatively low-power blue LED is excessive, causing unnecessary loss
