Abstract

A structure of a super-thin heat plate comprising surrounding bodies having a thin plate shape and supporting body is disclosed. Each supporting body have function of capillarity and is enclosed within the surrounding bodies. The surrounding bodies and the supporting body are connected by a plurality of welding spots, and the edges are properly sealed. The supporting body is distributed uniformly by a whole web structure. Thus, the heat plate wick structure is very stable with a preferred performance of heat transfer and can be finished easily. In mass production, the structure still has a high stability.

Claims

1. A structure of a super-thin heat plate comprising one or more surrounding bodies having thin plate shapes and supporting body, each supporting body having a capillarity and being enclosed within the surrounding bodies, the surrounding bodies and the supporting body are connected by a plurality of welding spots, and the edges are properly sealed.

2. The structure of a super-thin heat plate according to

claim 1

, wherein the supporting body is a metal plate.

3. The structure of a super-thin heat plate according to

claim 2

, wherein a plurality of blanking holes are formed on the supporting body by blanking.

4. The structure of a super-thin heat plate according to

claim 3

, wherein the ban kg holes on the supporting body are arranged as a long strip shapes, concentric circles, or radiating shapes.

5. The structure of a super-thin heat plate according to

claim 3

, wherein the edge of each blankling hole is installed with wick structures having a plurality of concave holes.

6. The structure of a super-thin heat plate according to

claim 3

, wherein the edge of each blanking hole is installed with wick structures having a plurality of chamfers.

7. The structure of a super-thin heat plate according to

claim 3

, wherein the supporting body is locally installed with non-conductive area within blanking holes by blanking.

8. The structure of a super-thin heat plate according to

claim 1

, wherein the supporting body is installed between the upper and lower surrounding bodies.

9. The structure of a super-thin heat plate according to

claim 1

, wherein the sealing edges between the surrounding bodies and the supporting body have wave shapes, and the openings are sealed by adhering with tin.

10. The structure of a super-thin heat plate according to

claim 1

, wherein the each surrounding body has a round tube, a supporting body is inserted into the surrounding body, and then the tubular surrounding body is collapsed so as to form as a thin plate.

11. The structure of a super-thin heat plate according to

claim 1

, wherein fixing holes are formed by blanking, the outer periphery of each fixing hole is blanked with concave portions, thereby, the periphery of the Sing holes are jointed tightly, and the fixing holes are tightly sealed by adhering with tin.

12. The structure of a super-thin heat plate according to

claim 1

, wherein the supporting body is a metal web having function of capillarity.

13. The structure of a super-thin heat plate according to

claim 1

, wherein a proper wick structure or other heat transfer material is formed between the supporting bodies and the surrounding body,.
