Heat pipe

Abstract

The invention relates to heat pipe. It is set evaporating part and condensing part. It includes the following structure: circulation fluid storage space, box type shell, capillary structure in shell inner wall, passage supplied for gas state circulation fluid to flow, and heat exchange unsmooth in the evaporating part. It has the advantages that it can maximize exchange area to relatively increase heat exchange efficiency; it can prevent bubble to increase heat exchange efficiency when the phase of the heat tube is changed.

Description

(1) Technical field [0001] The present invention relates to heat pipe technology, in particular to a heat pipe that utilizes the phase transition of the fluid state to release the heat stored in the fluid from a heat source, thereby achieving the purpose of heat conduction. (2) Background technology [0002] The so-called heat pipe is a component that uses the latent heat required by the fluid in the process of its state mutual conversion to make the fluid conduct heat from a place with a high heat density to a place with a low heat density. [0003] Because it utilizes the principle of mutual conversion of fluid states, the thermal conductivity of the heat pipe is higher than that of any known metal. [0004] In fact, the heat pipe that circulates inside has a thermal conductivity hundreds of times higher than that of silver and copper, which have very high thermal conductivity, in the normal temperature range. [0005] The shape of this heat pipe is generally divided into...

Problems solved by technology

Therefore, relatively speaking, the original heat pipe has the problem of low heat conduction efficiency.

[0013] In addition, the circulating fluid in the evaporating part 7 relies on the heat from the heat source for state transformation and reaches a boiling state. However, if the temperature is too high, the circulating fluid will boil in a film shape after reaching boiling, which leads to the problem of reduced heat transfer efficiency.
