Method for manufacturing temperature equalizing device without liquid injection tube and temperature equalizing device manufactured by using method

Abstract

The invention discloses a method for manufacturing a temperature equalizing device without a liquid injection tube and a temperature equalizing device manufactured by using the method. The manufacturing method comprises the following steps: (a) preparing an upper shell and a lower shell, and forming an accommodating space between the upper shell and the lower shell; (b) placing a capillary material and a support device into the accommodating space, welding and sealing the joint between the upper shell and the lower shell, and preserving a gap: (c) sintering; (d) injecting a liquid state working medium into the accommodating space; and (e) putting a combination of the upper shell and the lower shell into which the liquid state working medium is injected in the step (d) into a vacuum environment, and rapidly welding and sealing the gap. According to the manufacturing method, a temperature equalizing device which has high radiating property and is not provided with any exposed liquid injection tube can be manufactured.

Description

technical field [0001] The present invention is related to heat transfer technology, in particular to a method for manufacturing a uniform temperature device without a liquid injection pipe and a temperature uniform device made by the manufacturing method. Background technique [0002] Traditional heat transfer devices, such as flat plate heat pipes, loop heat pipes or uniform temperature heat transfer plates, all use the principle of phase change of working fluid to achieve heat transfer effect. [0003] When manufacturing the traditional uniform temperature heat transfer plate, it must be welded around it first, and then follow the steps of drilling, welding pipe, vacuum liquid injection, sealing the pipe opening and spot welding to complete it; When punching the upper and lower plate covers of the heat transfer plate, reserve liquid injection holes to omit the above-mentioned drilling steps. However, the uniform temperature heat transfer plate made by the above manufactu...

Problems solved by technology

However, the uniform temperature heat transfer plate made by the above manufacturing method usually leaves a liquid injection pipe with a length of 0.5 to 3 cm, and it is often difficult to control the manufacturing process, which often results in the benefit of uniform temperature or heat transfer. Indistinct

Furthermore, the exposed liquid injection tube is likely to become a place of stress concentration, resulting in easy damage, poor reliability, and easy collisions and fractures due to its convexity.
