Heat pipe

Abstract

Present invention discloses a thermal pipe. It contains sealed external use container with heat conductive material and filled operating fluid. It features said heat conductive material being foamed metal. Due to foam copper etc foamed metal having uniform pore with fine connectivity and simple process, the heat conductive material made from said foamed metal can absorb uniformly operating fluid like sponge and equalization dispersed over thermal pipe circumference, letting any point of thermal pipe heat radiation, said invention having fast heat transfer, high heat conduction quantity, less loss, yield quantity, low production costs, simple manufacturing process etc advantages.

Description

【Technical field】 [0001] The invention relates to a heat pipe, in particular to a heat pipe in which metal foam is arranged. 【Background technique】 [0002] At this stage, metal foams such as copper foam have been widely used in the fields of filtration, separation, sound absorption, flame retardancy and catalysis. There are many methods for their production. For example, patent 00127500.3 introduces a metal foam manufacturing method with uniform pores and simple process. The percolation method has good formability and stable quality. [0003] As we all know, the heat conduction of the heat pipe is the mechanism of using the latent heat of the working fluid in the tube to transport heat when the temperature changes. Because it can operate under a small temperature difference, it can have an amazing heat transfer, so it has the reputation of a thermal superconductor. . The current heat conduction materials used in heat pipes are copper mesh, copper fiber, copper powder sint...

AI Technical Summary

Problems solved by technology

The current heat conduction materials used in heat pipes are copper mesh, copper fiber, copper powder sintered or copper granule. Fast, high output, but high defect rate in subsequent processing, large damage to finished products, and low thermal conductivity durability; although copper fiber-like materials are low in production cost and high in output, they have large post-processing deformation, low thermal conductivity in flattened form, and product scrapping Large; copper powder sintered material has fast heat conduction, but its production cost is high, output is low, loss is large, and the defective rate of post-processing products is high; copper granular material has low cost, fast heat conduction, and high output, but subsequent processing is easy to deform and process Low thermal conductivity and high defective rate after finished product processing

As the operating speed of various machines and equipment is getting higher and higher, the heat generated is increasing greatly. The above-mentioned heat-conducting materials can no longer meet the demand of heat dissipation. Therefore, it is absolutely necessary to provide a better heat dissipation performance. heat pipe
