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

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Please refer to Fig. 1 and Fig. 2 together, it is the first embodiment of the heat pipe of the present invention, and this heat pipe is a single pipe type heat pipe 100, comprises a hollow airtight casing 110, has a cavity 120 therein; The working fluid 130 in the heat pipe 110 ; a rotating device 140 arranged axially along the cavity 120 to accelerate the flow of the working fluid 130 in the heat pipe 100 ; and a driving device 150 arranged at one end of the casing 110 .

[0018] Wherein, the hollow airtight casing 110 usually includes an evaporating end A1 and a condensing end B1, the evaporating end A1 is in contact with a heat source 160, in order to increase the contact area between them, a heat dissipation patch 112 can be arranged at the evaporating end A1, When the heat pipe 100 is in use, the heat dissipation patch 112 is closely attached to t...

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 invention relates to the technical field of heat transfer, and in particular relates to a heat pipe which uses the flow of working fluid to transfer heat. 【Background technique】 [0002] In recent years, with 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 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 dissipation device is currently the most widely used and most mature heat dissipation method, such as finned heat dissipation device, which conducts the heat generated by the heat source to the heat dissipation fin through the metal base, and then uses the large heat dissipa...
