## Abstract

A vapor chamber and a manufacturing method and equipment thereof includes: manufacturing an upper cover, a lower cover and a copper mesh, fixing the copper mesh in a groove on the upper cover; adding a predetermined amount of water into the groove; placing the lower cover on the upper cover on a side of the upper cover where an opening of the groove is located; vacuuming the upper cover and the lower cover located in a sealed working cavity; pressing the upper cover and the lower cover located in the sealed working cavity together by a compression assembly; and performing a welded edge sealing on the upper cover and the lower cover in the sealed working cavity.

## Claims

### Claim 1

A manufacturing method of a vapor chamber, comprising:
manufacturing an upper cover, a lower cover and a copper mesh,
fixing the copper mesh in a groove on the upper cover;
adding a predetermined amount of water into the groove;
placing the lower cover on the upper cover on a side of the upper cover where an opening of the groove is located;
vacuuming the upper cover and the lower cover located in a sealed working cavity;
pressing the upper cover and the lower cover located in the sealed working cavity together by a compression assembly; and
performing a welded edge sealing on the upper cover and the lower cover in the sealed working cavity.

### Claim 2 (depends on 1)

The manufacturing method of the vapor chamber according to claim 1, wherein when adding the predetermined amount of water into the groove and placing the lower cover on the upper cover on the side of the upper cover where the opening of the groove is located, the upper cover is located outside the sealed working cavity.

### Claim 3 (depends on 2)

The manufacturing method of the vapor chamber according to claim 2, wherein the sealed working cavity is formed by a vacuum box body and a sealing door panel, a lower wall of the vacuum box body is provided with a window, the sealing door panel is vertically slidable below the vacuum box body, when adding the predetermined amount of water into the groove and placing the lower cover on the upper cover on the side of the upper cover where the opening of the groove is located, the upper cover is on the sealing door panel, and after placing the lower cover on the upper cover on the side of the upper cover where the opening of the groove is located, the sealing door panel is moved up until the sealing door panel seals and covers the window.

### Claim 4 (depends on 3)

The manufacturing method of the vapor chamber according to claim 3, wherein when placing the lower cover on the upper cover on the side of the upper cover where the opening of the groove is located, the lower cover partially covers the groove to form an outgassing path.

### Claim 5 (depends on 4)

The manufacturing method of the vapor chamber according to claim 4, wherein a plurality of outgassing paths are formed, and the plurality of outgassing paths are uniformly distributed around a center of the groove in a circular manner.

### Claim 6 (depends on 4)

The manufacturing method of the vapor chamber according to claim 4, when adding the predetermined amount of water into the groove and placing the lower cover on the upper cover on the side of the upper cover where the opening of the groove is located, the upper cover is located in a predetermined position in a horizontal direction, and before pressing the upper cover and the lower cover located in the sealed working cavity together, a position of the lower cover is adjusted in the horizontal direction relative to the upper cover.

### Claim 7 (depends on 6)

The manufacturing method of the vapor chamber according to claim 6, wherein the outgassing path extends along an edge of the opening of the groove, and when pressing the upper cover and the lower cover located in the sealed working cavity together, a guide component on the compression assembly converts a downward pressure into a horizontal force to perform a positional adjustment of the lower cover.
