Fully-sealed liquid crystal projection light machine device with efficient heat dissipation function

Abstract

The invention discloses a fully-sealed liquid crystal projection light machine device with an efficient heat dissipation function. The device comprises a sealed shell with an accommodating space inside; a light source, a first heat pipe radiator assembly, a first cooling fan and a second cooling fan, which are all arranged outside the sealed shell; a first optical assembly, a second optical assembly and a liquid crystal screen which are installed in the sealed shell; a second heat pipe radiator assembly and a driving fan. First heat dissipation fins are fixedly installed outside the sealed shell and are close to the second cooling fan, and the second cooling fan is communicated with the first cooling fins through an air channel. The first cooling fins are directly communicated with secondheat dissipation fins or are communicated with the second cooling fins through the heat pipes. The internal heat is quickly transferred to the outside, and the heat dissipation is enhanced outside, sothat the heat exchange efficiency and the heat dissipation efficiency can be effectively improved, and the heat dissipation effect is improved.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation in optical projection devices, and in particular relates to a fully sealed liquid crystal projection light-mechanical device with high-efficiency heat dissipation. Background technique [0002] With the continuous development and progress of electronic technology, projectors are widely used in daily life. A projector, also known as a projector, is a device that can project images or videos onto a screen, and can be connected to computers, VCD, DVD, BD, game consoles, DV and other devices through different types of interfaces to play corresponding video signal. Among them, the LCD liquid crystal projector is a type of projector. The LCD liquid crystal projector has the advantages of better color reproduction, high resolution, small size and light weight. It is also very convenient to carry. It is the mainstream in the projector market. product. [0003] At present, projection devices ba...

AI Technical Summary

Problems solved by technology

Through the analysis, it can be seen that in the disclosed heat dissipation structure, the heat inside the camera is mainly received by the closed cavity itself, and then dissipated through radiation and natural convection. The heat transfer energy is small, the heat exchange efficiency is low, and the heat dissipation effect is poor. , can not meet the disadvantages of high power demand
