The hollow plate body is formed by combining two cover plates separated from each other, and the two cover plate edges are sealed to each other. That is, the two cover plates are combined, and after forming a capillary structure inside the two cover plates, the two cover plate edges are sealed. In addition, the sealing tube is inserted into the two cover plate inlets, the working fluid is injected through the sealing tube, and the gas is discharged from the vapor chamber.

In the prior art, a welding operation is performed on the edge of the vapor chamber to seal the coupling portion, that is, two cover plate edges are symmetrically aligned, and then welded to each other. In addition, the working fluid is injected into the vapor chamber to deliver energy while the working fluid circulates inside the plate body. However, since the contraction and expansion of the steam chamber is repeated according to the change in the internal temperature of the steam chamber, it is important to improve the sealability of the edge of the steam chamber. As such, it is important to reduce the defect rate of the product by improving the work quality of the welding operation, but this increases the manufacturing cost of the steam chamber.

In order to solve the problems of the prior art described above and to improve them, the present inventors devote themselves to the research based on the principle of science, and finally, the present invention has been completed to solve the problems of the prior art described above effectively and reasonably.

Still another object of the present invention is to provide an edge coupling structure of the steam chamber in which coupling sealing is improved.

In order to achieve the above object, the steam chamber provided by the present invention comprises a first cover plate, a second cover plate, a capillary structure and a working fluid. The first cover plate is bent extends to form a first bent portion, the second cover plate is coupled to the first cover plate. The edge portion of the second cover plate is also bent and extended so that the second bent portion overlaps the first bent portion, and the first bent portion is tightly fixed while surrounding the second bent portion. The capillary structure is formed inside the first cover plate and the second cover plate, and the working fluid is injected between the first cover plate and the second cover plate.

In order to achieve the above object, the edge coupling structure of the steam chamber provided by the present invention comprises a first cover plate and a second cover plate. The first cover plate is bent extends to form a first bent portion, the second cover plate is coupled to the first cover plate. The edge portion of the second cover plate is also bent and extended so that the second bent portion overlaps the first bent portion, and the first bent portion is tightly fixed while surrounding the second bent portion.

Compared with the prior art, the vapor chamber and its edge coupling structure provided by the present invention allow the length of the first bent portion to be formed longer than the length of the second bent portion, so that the second cover plate is coupled with the first cover plate. After bending the first bent portion to wrap the second bent portion, the first bent portion and the second bent portion are pressed to be tightly fixed by pressing the first bent portion that is bent by using a press tool. The sealing property of the coupling part of a cover part was improved. Through the above-described structure, the gas or liquid inside the vapor chamber is not leaked from the engaging portion of the first cover portion and the second cover portion. In addition, there is no need to weld the joints in particular, thereby reducing the defect rate in the manufacturing process and reducing the production cost, thereby combining practicality and economics.
