## Abstract

A heat dissipation component is disclosed. The heat dissipation component has a main body. The main body has a first metal plate body and a second metal plate body. The first and second metal plate bodies together define a chamber. A capillary structure layer is disposed in the chamber and a working fluid is filled in the chamber. An outer periphery of the chamber of the main body has a flange section. The flange section has a sintered welding section. The sintered welding section is perpendicularly connected with the first and second metal plate bodies. Such that, the connection and sealing of the welded first and second metal plate bodies can be enhanced.

## Claims

### Claim 1

A heat dissipation component comprising a main body, the main body having a first metal plate body and a second metal plate body, the first and second metal plate bodies being made from titanium or titanium alloy and together defining a closed chamber, a surface of the closed chamber having at least one capillary structure layer, a separate capillary structure member being disposed between the first and second metal plate bodies, a working fluid being filled in the closed chamber, an outer periphery of the closed chamber of the main body having a flange section, the flange section having a sintered welding section, the sintered welding section being perpendicularly connected with the first and second metal plate bodies by fillet welding.

### Claim 2 (depends on 1)

The heat dissipation component as claimed in claim 1, wherein the sintered welding section perpendicularly penetrates through the entire plate thickness of the first metal plate body and extends to a position of one-third to two-third the plate thickness of the second metal plate body.

### Claim 3 (depends on 1)

The heat dissipation component as claimed in claim 1, wherein the main body has a support structure, the support structure being formed by means of external force deformation or cutting processing or externally added component as a support member, the cutting processing being such that one side of one of the first and second metal plate bodies is selectively cut to form raised structures abutting against and supporting the other plate body, the support structure formed by means of external force deformation being such that an external force is selectively applied to one side of one of the first and second metal plate bodies to be recessed toward the other side so as to form the support structure, the externally added component being such that a support body such as a support column is disposed between the first and second metal plate bodies as the support structure.

### Claim 4 (depends on 1)

The heat dissipation component as claimed in claim 1, wherein the capillary structure member is a sintered powder plate body, a fiber body, a mesh body, a waved plate or a plate body with multiple channels.
