Heat pipe and radiating model group

Abstract

The invention relates to a heat pipe, which includes a cover body and a body, the body includes an evaporation chamber, a condensation chamber, an evaporation channel and a return flow channel, a plurality of partitions are arranged in the condensation chamber, at least one partition It has a cavity that communicates with the outside world. The evaporation cavity has a steam output side and a liquid input side. The condensation cavity has a steam input side and a liquid output side. The evaporation channel is arranged between the steam output side and the steam input side. Between the evaporation chamber and the condensation chamber, the return passage is set between the liquid output side and the liquid input side and communicates the condensation chamber with the evaporation chamber, and a working fluid is filled in the evaporation chamber, the condensation chamber, the return passage and the evaporation passage. in the channel formed. In addition, the invention also provides a cooling module with the heat pipe. The heat pipe can effectively solve the heat dissipation problem of the notebook computer which is developing towards light, thin, short and small.

Description

【Technical field】 [0001] The invention relates to a heat pipe and a cooling module with the heat pipe. 【Background technique】 [0002] A heat pipe is a heat transfer device that holds a proper amount of working fluid in a sealed, low-pressure metal shell with good thermal conductivity. Its working principle is: use the working fluid to convert vapor and liquid in the shell to absorb or release heat. The working fluid is usually a liquid substance with high heat of vaporization, good fluidity, stable chemical properties, and low boiling point, such as water, ethanol, acetone, etc. The heat pipe has an evaporating end and a condensing end. When the evaporating end is in contact with the heat source to absorb heat, the working fluid inside is heated and evaporated and absorbs a large amount of heat of vaporization. The formed gas quickly diffuses to the condensing end to cool and release heat, and then forms again after cooling. The liquid flows back along the inner wall of th...

Problems solved by technology

Due to the existence of this shearing force, the circulation speed of the working fluid in the heat pipe 10 is greatly slowed down, which reduces the heat transfer performance of the heat pipe 10. For the long heat pipe with a smaller diameter of the shell 102, even the condensed liquid cannot Smoothly return to the evaporation section A for circulation heat dissipation
