Circulation flowing pulsating heat pipe for cooling electronic device

Abstract

This invention relates to a circulation flow pulsation thermal tube suitable for cooling spare part of semiconductor devices and other solid devices composed of two connected and mutually parallel-arrayed thick straight channel and thin straight channel, two adjacent channels are connected by an angle pipe. A heat conduction working solution forms a single-way plug flowing under the pressure generated by heat action in the channel, which absorbs heat and evaporates at the heating section and discharges heat and condenses at the radiation section. This invented pulsation thermal tube has high conduction limit and low resistance.

Description

Technical field:

[0001] The invention belongs to the technical field of electronic cooling, and relates to components for cooling semiconductors or other solid devices. Background technique:

[0002] With the continuous development of electronic assembly technology, the physical size of components is getting smaller and smaller, and the assembly density is increased; the performance of chips is improved, and the heat generated by them is also increased accordingly, resulting in the formation of high heat density of electronic devices. Therefore, it is more and more important to find effective heat dissipation methods for electronic devices.

[0003] The conventional heat dissipation method mainly relies on the heat sink on the radiator to dissipate heat through heat conduction, which cannot meet the heat dissipation requirements of high heat flux.

[0004] As shown in Figure 4: the circulation type heat pipe is a serpentine pipe, and its two ends are sealed and connected to...
