Description

Technical Field

[0001] The utility model relates to the technical field of heat pipe processing, in particular to a flattening device for processing ultra-thin heat pipes. Background Art

[0002] As a heat transfer element, heat pipes can transport liquid and gaseous media, and quickly transfer the heat of heating objects to the outside of the heat source through heat pipes. Their processing and manufacturing process is more suitable for large-scale production. At the same time, they have stable performance, high reliability, and good post-processing performance. Therefore, their application range is very wide. Heat pipes are often made into a flat shape during processing and design to fit the small installation space in the electrical and electronic equipment that carries them. In order to further reduce the demand for heat pipe installation space, ultra-thin heat pipe fittings are now developed.

[0003] Flattening of ultra-thin heat pipes is a secondary processing of heat pipes, which is often carried out after the entire pipe is formed. However, during the flattening, the pipe is usually preheated first, which can help the pipe to deform more easily. However, during the deformation process of the pipe, the structure will generate a lot of internal heat. Along with the preheating of the ultra-thin material, the pipe will carry heat for a long time after flattening, and it is difficult to dissipate quickly, which has a great impact on the metal structure and performance of the ultra-thin heat pipe, and seriously causes the pipe to crack.

[0004] Therefore, in order to solve the problem that the internal heat accumulation caused by preheating and deformation during the flattening process of the above-mentioned ultra-thin heat pipe will damage the metal structure and performance of the thin-walled pipe, a heat pipe flattening device with a synchronous auxiliary heat dissipation structure can be designed.
