Problems solved by technology

[0006] However, in actual use, the above-mentioned protruding flat sealing end 112 is easily broken by an external force, causing the heat pipe 10 to leak, and has an unattractive appearance and the flat sealing end 112 will increase the length of the heat pipe 10, which is relatively necessary. The larger placement space, and the method of injecting the working fluid first and then vacuuming it, will suck back part of the working fluid that has been injected into the hollow tube body 11, resulting in the inability to accurately control the internal pressure of the hollow tube body 11. The number of working fluids and the quality of the heat pipe 10 can be effectively guaranteed. In addition, the manufacturing process of the existing heat pipe 10 is complicated because it is filled first and then vacuumed.

Embodiment Construction

[0035] For convenience of description, in the following embodiments, similar components are denoted by the same reference numerals.

[0036] Such as Figure 5 , 6 , Shown in 8, the first preferred embodiment of the heat pipe 1 of the flat mouth type sealing of the present invention is to be suitable for first degassing with a degassing filling needle 21 (containing degassing needle, filling needle), then injecting an appropriate amount Filling, the filling is working fluid; the heat pipe 1 includes a metal hollow cavity 3 including an opening 31, a metal sealing seat 4 that is fixedly sealed to the opening 31, and a metal sealing seat 4 that is filled in the sealing seat 4 The inner sealing body 5, and a positioning block 6 closely attached to the sealing body 5.

[0037] The hollow body 3 includes an opening 31 and an inner chamber 33 defined by an inner surface 321 surrounding a wall 32 .

[0038] The sealing seat 4 is fixedly sealed to the opening 31 of the hollow cavity...

Abstract

The present invention is flat mouth heat pipe and its sealing method. The heat pipe includes one hollow cavity with opened mouth and one mouth sealing seat to seal the opening. The mouth sealing seat includes one filling port communicated with the hollow cavity. The sealing method includes fixing one sealing body in the filling port, piercing syringe into hollow cavity via the sealing body and the filling port for deairing and filling operation, withdrawing the syringe and sealing the pore by means of the elastic force of the sealing body.

Description

(1) Technical field [0001] The invention relates to a flat-sealed heat pipe, in particular to a flat-sealed heat pipe capable of maintaining the integrity of the appearance and a sealing method thereof. (2) Background technology [0002] A kind of manufacturing method of existing heat pipe is to first construct a metal hollow pipe body with an open end and a boundary to define the inner cavity, and then inject an appropriate amount of working fluid into the hollow pipe body from the open end, and finally The hollow tube is vacuumed and then sealed (ie, the open end of the hollow tube is sealed). [0003] The sealing method of above-mentioned existing heat pipe comprises the following steps: [0004] (A) if figure 1 , 2 As shown, the opening end 111 of the hollow pipe body 11 is clamped and processed by a machine first, so that it forms a basic shape of a heat pipe 10; [0005] (B) if figure 2 , 3 As shown, then use a machine tool to cut off the top section 1121 of a f...
