Problems solved by technology

However, when the liquid filling is stopped, a lot of working fluid vapor will remain in the passage tube between the heat pipe liquid filling port and the collecting bottle, and the heat pipe filling liquid volume is usually several milliliters, so that the error between the actual filling amount of the heat pipe and the expected filling amount is large. Therefore, it is difficult for the device to achieve precise control of the filling amount of the working fluid

Abstract

The present invention provides vacuum liquid-filling equipment. It includes the following several portions: a liquid conveying system for conveying liquid into the container to be filled with liquid; an evacuation system for evacuating the interior of container to be filled with liquid; and a freezing system for freezing the liquid filled into the container interior. Said invention also provides a vacuum liquid-filling method by using above-mentioned equipment.

Description

【Technical field】 [0001] The invention relates to the field of heat conduction, in particular to a vacuum liquid filling device which can be used for filling heat pipe working fluid and a vacuum liquid filling method using the device. 【Background technique】 [0002] In recent years, with the rapid development of electronic technology, the high frequency and high speed of electronic devices and the density and miniaturization of integrated circuits have caused a sharp increase in the heat generated by electronic devices per unit area. The heat pipe technology, with its high efficiency, compactness, flexibility and reliability, is suitable for solving the heat dissipation problems of current electronic devices due to performance improvement, and has gradually become the mainstream heat dissipation method of current electronic devices. [0003] A heat pipe is a hollow sealed tube, usually including a shell, a liquid-absorbing core (capillary structure) close to the inner wall o...
