Hot pipe

Abstract

The invention provides a heat pipe, comprising a hollow sealing shell, working fluid in said shell and a rotary device used to accelerate the flowing speed of working fluid in heat pipe. Said rotary device comprises rotary shaft set in shell in axial direction and agitating part formed on said rotary shaft. Cycle flow of working fluid in heat pipe is forced so that thermal migrating rate and heat transferring efficiency are improved by the rotation of rotary device in heat pipe.

Description

【Technical Field】 [0001] The present invention relates to the field of heat transfer technology, and particularly relates to a heat pipe that utilizes the flow of a working fluid to transfer heat. 【Background technique】 [0002] In recent years, the rapid development of electronic technology, the high frequency and high speed of electronic devices, and the density and miniaturization of integrated circuits have caused a sharp increase in the amount of heat generated by electronic devices per unit area. In order to dissipate the high heat generated by electronic devices, there are currently three general heat dissipation methods, namely, air-cooled heat sinks, liquid-cooled heat sinks and heat pipes. [0003] Air-cooled heat sink is currently the most widely used and most mature heat dissipation method, such as a fin type heat sink, which conducts the heat generated by the heat source to the heat sink through a metal base, and then uses the larger heat dissipation area of ​​the he...

Problems solved by technology

However, when it uses the flow of working fluid to transfer heat, the heat transfer efficiency of the heat pipe also depends on the flow velocity of the working fluid, and the existing heat pipe has not improved the flow velocity of the working fluid, which severely limits the heat transfer efficiency of the heat pipe. Improvement of transmission efficiency
