Problems solved by technology

However, although the nozzle end 10a of the heat pipe 1a is narrowed, it is beneficial to the welding process, but it causes the generation of the invalid end of the heat pipe 1a, especially when the heat pipe 1a is applied to the occasion of connecting fins in series. The end 10a is not only unable to connect the fins in series due to the reduced pipe diameter, but also occupies space because the nozzle end 10a must protrude outside the fin group

Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings, wherein all the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention.

[0031] Such as figure 2 Shown is a schematic view of the three-dimensional appearance of the present invention. The invention provides a heat pipe pressing and sealing method and its structure. The sealing structure of the present invention is formed on the sealing end of the heat pipe 1 to make the inside of the heat pipe 1 in a sealed state, so that the working fluid of the heat pipe 1 can be changed mutually, thereby ensuring that the function of the heat pipe 1 can be realized normally. Simultaneously, after the sealing end of heat pipe 1 is sealed, still can make cooling fin 4 (as Figure 9 shown) connected in series.

[0032] When the above-mentioned sealing structure is formed, the sealing end of the heat pipe 1 is firs...

Abstract

A method for sealing the end of heat tube by pressing includes such steps as making a reduced tube end with two conic surfaces, pressing on the reduced tube end for sealing it, treating the deformed end to make the shape of reduced tube end be consistent with that of tube body. The pressed tube end is extended to form the side edge.

Description

technical field [0001] The invention relates to a heat pipe pressing and sealing method and its structure, in particular to a pressing and sealing method and its structure which can increase the number of cooling fins pierced at the sealing end of the heat pipe. Background technique [0002] figure 1 What is shown is the sealing structure of the heat pipe 1a in the prior art. figure 1 The sealing structure of the heat pipe 1a shown in the prior art is first to shrink the nozzle end 10a of the heat pipe 1a into a shrinking tube part 100a through a shrinking tube manufacturing method, and then use the tube sealing die pliers to tighten the end of the tube part 100a to form a flattened tube. zone 101a, and then weld (not shown) on the upper end of the crushed zone 101a, thereby sealing the nozzle end 10a of the heat pipe 1a. [0003] In the sealing structure of the heat pipe 1a of the above-mentioned prior art, the main purpose of reducing the nozzle end 10a to the shrinkage ...
