Self-powered circulating type uniform-temperature radiating device

Abstract

The invention discloses a self-powered circulating type uniform-temperature radiating device. The device comprises a device body, at least one inner circulating running channel which is arranged in the device body and in a circular closed running channel form, working liquid stored in the inner circulating running channel, and a heating part arranged at the outer part of the device body, wherein a large hole evaporating section and a small hole reflowing section are arranged in the inner circulating running channel; the wall thickness of at least local structure of the device body is more than the hole diameter of the small hole channel reflowing area. According to the device, when the working liquid in the inner circulating running channel is evaporated into air, the air can flow from the large hole evaporating section to the small hole reflowing section to enter an one-away anti-returning circular flowing state; the heat introduced by the heated part is transferred to each part of the device body to achieve the effect of quickly radiating at uniform temperature.

Description

technical field [0001] The invention relates to a heat dissipation device; in particular, it relates to an innovative heat dissipation device capable of achieving the function of self-powered circulation uniform temperature and heat dissipation. Background technique [0002] At present, the common vacuum radiator structure is mainly in two forms of heat pipe and vapor chamber, and these two radiator structures use the tube body or plate shell as the external structure to relatively form an internal hollow chamber. The shape of the hollow chamber is a long and extended single space form for the heat pipe, and the uniform temperature plate is a planar extended and enlarged space form. The hollow chamber is evacuated and injected with a working fluid to utilize the working The liquid can be evaporated by heat and then condensed into a liquid phase change repeatedly to achieve the function of accelerating the heat dissipation efficiency; and in terms of the operation and flow pa...

Problems solved by technology

[0003] The radiator structures such as heat pipes and vapor chambers mentioned in the previous paragraph still have some problems and disadvantages in practical application experience. For example, the flow paths of liquid and evaporated gas flow in opposite directions in the same space, often It is easy to cause the conflict between the moving lines of the gas and the liquid during the flow process, resulting in mutual interference and mutual weakening of the flow efficiency; moreover, the flow of the liquid and the gas in the aforementioned heat pipes and vapor chambers operates in a horizontal direction. Therefore, it is obviously not suitable for product structures that must conduct vertically guided heat dissipation (such as the suspension frame of a chandelier). It can be seen that the existing radiators still have certain limitations in terms of practical application. Limitations exist. Therefore, with the diversification of product structures that require heat dissipation, how to develop an innovative heat dissipation structure that can be applied to different product forms is actually a goal and direction for the relevant industries to think about and break through.
