Problems solved by technology

[0012] Although the filling method of the (5) miniature heat pipe can achieve accurate filling volume, the current sealing can only be aimed at silicon wafers, which is more difficult for the sealing of metal micro heat pipes, and generally requires a pressure vessel and an auxiliary heating control system. There is still a long way to go for practical application
The filling method of the (6) miniature heat pipe contains a lot of empirical operation methods, and it is difficult to guarantee the versatility and accuracy.

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 As shown, the main part of the filling device of the present invention is a cylinder 1, which includes a first piston chamber 31 and a second piston chamber 32, and the top of the cylinder 1 is provided with a cap chamber 4 for communication The first piston cavity 31 and the second piston cavity 32 . The upper part of the first piston chamber 31 is provided with an opening, and a liquid outlet channel 2 extends out of the cylinder 1 from the opening. There is a piston in sealing contact with the two piston chambers respectively, that is, the first piston 51 and the second piston 52 . The bottom of the piston is connected with a rigid connecting rod, the first connecting rod 61 is connected with the first piston 51 , and the second connecting rod 62 is connected with the second piston 52 . These two connecti...

Abstract

A filling apparatus for quantitatively filling liquid is composed of a cylindrical body for containing liquid in it and a liquid outlet channel. In said cylindrical body, there are the first and the second piston cavities, a capc avity communicated with said piston cavities, two pistons in said piston cavities (one for one), and two rigid piston rods extended out of the piston cavities. Said filling apparatus has also a linkage mechanism connected to two piston rods to make them move in reverse directions and a measuring element for directly measuring the quantity of filled liquid. Its advantage is high accuracy.

Description

technical field [0001] The invention relates to a liquid filling device, more specifically, the invention relates to a filling device capable of quantitatively filling liquid. Background technique [0002] Regarding the filling of working fluid in heat pipes, the document "Ma Tongze, Hou Zengqi, Wu Wenjun, Heat Pipe, Science Press, ISBN 7-03-002011-1, 1991, 277-282" introduces the filling of working fluid in the following heat pipes: Installation method: [0003] (1) Filling of sodium heat pipes, introducing the distillation sodium filling system; [0004] (2) Filling of water heat pipes, including vacuum filling method and boiling method without vacuum; [0005] (3) The filling of the controllable heat pipe is mainly how to control the amount of inert gas; [0006] (4) Filling of the cryogenic heat pipe. [0007] However, these four filling methods all belong to the category of large heat pipes. They are suitable for filling a large amount of working fluid, and the rela...
