Description

Radiating channel structure of single-chip LCD projector

Technical Field

The utility model relates to a monolithic LCD projector heat dissipation channel structure.

Background

The existing similar LCD projectors have poor radiating channels due to the limitation of volume and space, so that the brightness of the projected picture is not high or the working noise is high. The brightness of the single-chip LCD projector is closely related to the temperature of the display unit LCD and the backlight LED, and under constant power, the lower the temperature of the display unit LCD and the backlight LED is, the higher the brightness of a projected picture is.

The conventional single-chip LCD product has two general heat dissipation modes:

1. the double fans form a heat dissipation channel. One fan blows cold air into a channel between the LCD and the heat insulation glass, and the other fan blows the cold air onto the fins and the heat pipe to dissipate heat of the LED.

2. A single fan heat dissipation channel. The fan is vertically disposed between the LCD and the fin heat pipe. Because of the material size restriction, there is narrow drawback in the air intake of fan.
