Benefits of technology

[0005]Therefore, the present invention is to provide a vapor chamber having a casing formed by folding a board, and at least one side of the casing being formed by a folding edge, such that the length of a sealing edge of the vapor chamber can be reduced to achieve the effects of lowering the defective rate of the manufacture, completing the edge sealing operation quickly, and preventing the sealing edge from being cracked to extend the using life of the vapor chamber.

Problems solved by technology

However, the larger the edge of the vapor chamber, the more difficult is the manufacture of sealing the edge.
As a result, the problems of a high defective rate and inconvenience arise.
Particularly, the sealed edge may be cracked easily after the vapor chamber has been used in an environment of being heated on one surface of the vapor chamber and cooled on the other surface of the vapor chamber for a while, and the operating fluid sealed in the vapor chamber may be leaked, or the vapor chamber may fail to exchange heat when air enters into the chamber, or totally break down.

Abstract

A folding vapor chamber includes folding boards engaged and covered with one another, a folding edge formed between the adjacent folding boards and provided for connecting the folding boards integrally, and the adjacent folding boards being bent and folded by the corresponding folding edge and engaged with one another, and a capillary tissue installed at an internal surface between the folding boards. The casing is formed by the folding edge to reduce the length of the sealing edge of the vapor chamber, so as to achieve the effects of lowering the defective rate of the edge sealing operation, and preventing the sealing edge from being cracked easily.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a thermal conducting device, in particular to a vapor chamber produced by a folding method.BACKGROUND OF THE INVENTION[0002]In general, a vapor chamber is a hollow casing substantially in a flat slab shape, and the casing are formed by engaging two detachable folding boards, and a chamber is formed between the two folding boards and provided for installing a capillary tissue, an operating fluid and a support structure, etc. Since air must be removed or vacuumed in the casing, therefore the two folding boards must be soldered or thermally pressed after the two folding boards are engaged with each other, so as to seal the periphery of the two folding boards and facilitate the operation of removing air or vacuuming the vapor chamber.[0003]However, the larger the edge of the vapor chamber, the more difficult is the manufacture of sealing the edge. As a result, the problems of a high defective rate and inconvenience arise. Part...
