A flat panel display back air cooling device

Abstract

The invention relates to an air cooling device for the back of a flat-panel display, comprising: a fan and a heat dissipation box with air outlet holes; there are more than two fans, which are arranged on the left and right sides of the heat dissipation box and blow air to the middle of the heat dissipation box; Flow through the air outlet to the vertical direction. The air outlet is located on the upper side wall of the heat dissipation box; the lower side wall of the heat dissipation box gradually rises from both ends to the middle; the fans are arranged in pairs on the left and right sides of the heat dissipation box. The upper side wall is a flat plate, and the two side walls connecting the upper side wall and the lower side wall are vertical plates; the left and right shapes of the cooling box are symmetrical. The invention has the advantages of being able to control the fan according to the temperature situation; the noise emitted by the fan can be reduced due to the use of a low-power fan, and the entire cooling device has the advantages of compact structure, small space occupation, and remarkable heat dissipation effect, and is suitable for flat panel displays heat dissipation.

Description

technical field [0001] The invention relates to a cooling device, in particular to a forced air cooling device for the back of a flat panel display. Background technique [0002] At present, flat-panel displays, such as LCDs, are widely used in the electronic industry, and their sizes are also getting larger. The corresponding power consumption is also getting higher and higher, and the heat generated is also increasing. If the heat cannot be dissipated from the LCD in a timely and effective manner, the temperature of the LCD will be too high, even exceeding the temperature specification of the liquid crystal material, thereby affecting the reliability of the LCD. Especially in interactive multimedia teaching and conference systems, in order to protect the touchable LCD surface from being scratched by hard objects, a piece of transparent glass (or resin) is usually arranged in front of the LCD, and in order to ensure the display effect, the glass (or resin) and The gap on t...

Problems solved by technology

[0005] However, this structure with splitters in the middle, on the one hand, the strength will decrease after the airflow turns, and on the other hand, one fan supplies one air-cooling device, which requires a relatively large air volume of the fan, so it can only be used The volume is relatively large, the power is relatively high, and the noise generated by the fan is also relatively large.

In addition, the fan and shroud protrude from the middle of the air outlet channel, occupying a certain amount of space, causing the size of the air cooling device to become larger and the structure not compact
