Problems solved by technology

However, when the heat pipe is bent, there is a certain damage to the capillary structure in the shell, and the heat transfer capacity of the heat pipe is reduced to a certain extent every time it is bent, and there is an interface thermal resistance between the heat pipe and the radiator due to the combination, which also affects the heat dissipation device. overall cooling performance

Abstract

The invention discloses a heat abstractor for cooling a heating electronic component, and the heat abstractor comprises a heat conducting base seat processed and moulded by an integer, at least two heat conducting wing parts extending out of the heat conducting base seat at intervals, and a plurality of radiation fins which are arranged at intervals and extended out of the surface of the heat conducting wing parts. Communicated conduits are arranged in the heat conducting base seat and the heat conducting wing parts, and a right amount of working liquid is sealed in the conduits. Compared with the prior art, the conduits and the heat abstractor form an unassembled interface, which overcomes the unfavorable influences of the bending of the traditional heat tube and the interface heat resistance brought by the joint of the radiation fins.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device for electronic components. Background technique [0002] Electronic components such as the central processing unit (CPU) generate a large amount of heat energy when they are running. Especially with the continuous improvement of the processing capacity of electronic components and the smaller size, the unit calorific value is getting larger and larger. For this reason, the industry has adopted heat pipes as The components of the radiator, the heat transfer speed of the heat pipe is fast and the distance is long, and the heat conduction of each part of the radiator is connected through the heat pipe, which can quickly and evenly spread the heat of the electronic components to all parts of the radiator and quickly dissipate the heat outward, so The performance of the radiator is effectively improved. [0003] Generally, a heat pipe is provided with a capillary...
