Abstract

The invention discloses a heat dissipation system which is used for increasing the efficiency of traditional heat conducting pipes, promoting the efficient utilization of space and reducing the temperature in starting the heat conducting pipe. The heat dissipation system comprises an evaporator, a steam channel, a condensing area and a condensate channel; wherein, one end of the steam channel is connected with the evaporator and the steam channel is used for conveying the steam from the evaporator; the other end of the condensate channel is connected with the condensing area which is used for condensing the stream into the condensate, and the condensate channel is connected with the condensing area and the evaporator and one of the condensing area and the evaporator is provided with a capillary structure; the condensate channel and the steam channel are connected with the condensing area by the evaporator; the condensate returns to the evaporator by the condensate channel and transforms into other steam by an outer heat source in the evaporator.

Description

technical field [0001] The invention relates to a heat dissipation system, in particular to a heat pipe heat dissipation system comprising a flat plate evaporator. Background technique [0002] Thermal management is a necessary and challenging issue in various fields, such as the stabilization of permafrost, cooling of electronic equipment, and space vehicles. Among the many heat management methods, heat pipe (Heat Pipe) is a commonly used method. A heat pipe is a two-phase heat conduction device that conducts heat efficiently and effectively. [0003] Please refer to FIG. 1 , which is a schematic diagram of a conventional heat pipe device. In Fig. 1, the heat pipe 1 is mainly composed of a tube shell 11, a capillary structure (Wick Structure) 12 and an end cap 13, and its interior is maintained at a low pressure state, and an appropriate amount of low-boiling liquid 181 is placed in it. Liquids evaporate easily due to their low boiling points. The capillary structure co...

[0007] The above-mentioned known heat pipe evaporators are all cylindrical. For planar heat sources such as electronic chips, adapter elements are still needed to convert the cylindrical surface into a plane, so as to facilitate the heat dissipation design of the planar heat source. Such a design requires more adapter elements. Uncertainty, and increasing the thermal resistance will affect the performance of heat conduction
