Siphon heat dissipation plate and display device with the same

Abstract

The invention provides a siphon-type heat dissipation panel and a display device therewith. The siphon-type heat dissipation panel comprises a first panel body, a second panel body, and working solution. The first panel body is partly attached to the second panel body, and an accommodation chamber is formed between the first panel body and the second panel body. The working solution is disposed inthe accommodation chamber, and is accumulated in a bottom region of the accommodation chamber along the direction of gravity. When a heat source is attached to the siphon-type heat dissipation panel,the heat energy generated by the heat source is conducted to the working solution, and the working solution absorbs the heat energy and is evaporated into working solution steam. The working solutionsteam reaches the top region of the accommodation chamber for heat dissipation, and then is restored to the working solution which flows back to the bottom region of the accommodation chamber in thedirection of gravity. Therefore, the siphon-type heat dissipation panel can absorb the heat energy generated by the heat source, and can directly perform the heat conduction and dissipation, thereby improving the heat dissipation efficiency.

Description

technical field [0001] The present invention relates to a heat dissipation device, in particular to a siphon heat dissipation plate that can be applied in electronic devices and a display device with the siphon heat dissipation plate. Background technique [0002] Today's electronic display devices, such as LCD TVs or large screens, all have a display panel and a heat source inside, and the heat source is a light-emitting element, a light bar or a light-emitting diode. When the light generated by the heat source enters the display panel, the display panel will generate an image. However, since the heat source continuously emits light, it will also generate a large amount of heat energy. Therefore, it is necessary to add a heat sink to the electronic display device to assist in heat dissipation to avoid light-emitting elements. Or other internal components are damaged due to overheating. [0003] The heat dissipation device of the existing electronic display device is to att...

Problems solved by technology

In addition to conducting heat energy to assist heat dissipation, the heat sink or heat conduction sheet in the prior art does not have a strong heat dissipation function. When encountering large-scale screens and heat energy generated by a large number of heat sources, the heat dissipation efficiency cannot be improved. Therefore, Existing technology still needs improvement
