Abstract

The invention discloses a flat plate type loop heat pipe suitable for two vertical heat sources. The flat plate type loop heat pipe comprises an evaporator, an injection pump, a jet flow heat exchangecavity and a cooler, the bottom surface of the evaporator is a horizontal heat exchange surface, the side surface of the jet flow heat exchange cavity is a vertical heat exchange surface, a liquid outlet of the evaporator is connected with the injection pump, a gas outlet of the evaporator is connected with the injection pump, the injection pump is connected with the jet flow heat exchange cavity, and the jet flow heat exchange cavity is connected with a liquid inlet of the evaporator through the cooler. According to the flat plate type loop heat pipe suitable for the two vertical heat sources, the jet flow impact enhanced heat exchange technology is coupled with the loop heat pipe, so that the effect that heat dissipation is carried out on the two vertical heat sources is realized, and the advantages of high reliability and high jet flow impact heat exchange coefficient of the loop heat pipe are retained.

Description

technical field [0001] The invention belongs to the field of cooling and heat dissipation of electronic components, and relates to a heat pipe heat dissipation device, in particular to a flat plate loop heat pipe suitable for two vertical heat sources. Background technique [0002] With the continuous improvement of the integration and high frequency of electronic components, the calorific value continues to increase, and thermally induced failure has become the main form of failure of microelectronic devices. Taking a computer mainframe as an example, the common heat dissipation method is air cooling, and the heat dissipation device includes a finned heat sink and a fan. In order to dissipate the heat in time, the volume of the finned radiator above the CPU and the graphics card is constantly increasing, and the number and speed of the fans are also increasing, resulting in a large and heavy cooling device. And air cooling is limited by its inherent heat dissipation capaci...
