Liquid suction core support component and manufacturing method thereof and integrated hot pipe

Abstract

The invention relates to a liquid absorption core supporting element, a production method thereof and an integrated heat pipe. The liquid absorption core supporting element comprises a metal sheet of a wave belt shape formed by gear rolling, a metal sheet segment is provided between a wave crest and a wave trough, the wave crest and the wave trough are welded on the inner wall of the integrated heat pipe casing, a though hole is provided on the metal sheet segment, adjacent metal sheet fragments adhere together, and through holes on the metal sheet fragments are at least partially overlapped. The integrated heat pipe adopts the liquid absorption core supporting element, and the wave crest and the wave trough of the liquid absorption core supporting element metal sheet of a wave belt shape are connected on the inner wall of the integrated heat pipe casing. Metal sheets of a wave belt shape are formed by gear rolling and are connected in the integrated heat pipe by welding of wave crest and wave trough, overcoming problem of groove obstruction caused by melt welding liquid flowing into space between metal sheet segments. Metal sheets formed by gear rolling have smaller thickness and high porosity, thereby avoiding return liquid drying up and improving heat conduction effect of the integrated pipe.

Description

technical field [0001] The invention relates to heat transfer, mass transfer and heat dissipation technology, in particular to a liquid absorbent core supporting member and a manufacturing method thereof, and an integrated heat pipe using the liquid absorbent core supporting member. Background technique [0002] Integrated heat pipes that use the principle of heat pipe heat dissipation to dissipate heat and cool electronic components have been widely used. In order to meet the market demand, the requirements for the structure and performance of the integrated heat pipe are constantly increasing. On the one hand, to improve the heat transfer capability of the integrated heat pipe, it is necessary to maintain a sufficient vacuum cavity volume in the integrated heat pipe, and the liquid wick structure arranged in the vacuum cavity has a good capillary force to guide the flow of the liquid working medium. On the other hand, the shape of the integrated heat pipe is required to b...

Problems solved by technology

[0004] However, the supporting member of the above-mentioned structure has certain defects: the solder for brazing the metal sheet to the wall of the shell will melt into solder liquid during the welding process, and the solder liquid flows between the metal sheet through the gap between the crest and trough of the metal sheet In addition, the stamped metal sheet is limited by the process, its thickness is large, and its precision is low, so that the gap is small and the porosity is small, so the amount of backflow liquid is small, and it is easy to Dry-out occurs, making the heat transfer effect of the integrated heat pipe poor
