Abstract

A vapor chamber structure includes a main body. The main body has a first section, a second section, a capillary structure and a working fluid. The first section has a first chamber. The second section has a second chamber. The second section extends from one end of the first section in a direction away from the first section. The capillary structure is disposed on inner surfaces of the first and second chambers. The working fluid is filled in the first and second chambers. The vapor chamber structure has both heat spreading effect and remote end heat dissipation effect.

First claim

What is claimed is:

1. A vapor chamber structure comprising:
a main body comprising:
a first chamber having the form of a flat cuboidal body with a heat spreading surface;
a first heat conducting tubular portion extending from the first chamber in a direction away from the first chamber and having a second chamber communicating with the first chamber;
a second heat conducting tubular portion extending from the first chamber and having a third chamber communicating with the first chamber;
wherein the first heat conducting tubular portion and the second heat conducting tubular portion have the form of an elongated cuboidal body or an elongated cylindrical body or any elongated geometric body, and wherein by means of linear conduction, heat is transferred from the first chamber to a remote end of the first heat conducting tubular portion and a remote end of the second heat conducting tubular portion for heat exchange and dissipating the heat, and wherein the remote ends of the first heat conducting tubular portion and the second heat conducting tubular portion are positioned at different heights relative to the main body, and the remote ends of the first heat conducting tubular portion and the second heat conducting tubular portion are arranged at different heights and toward same direction or different directions;
a capillary structure disposed on inner surfaces of the first, second, and third chambers; and
a working fluid filled in the first, second, and third chambers.

2. The vapor chamber structure as claimed in claim 1 , wherein a second heat conducting tubular portion extends from one end of the first chamber, the second heat conducting tubular portion having a third chamber, the capillary structure extending to the third chamber to be also disposed on the inner surface of the third chamber, the working fluid being partially filled in the third chamber.

3. The vapor chamber structure as claimed in claim 2 , wherein the second chamber and the third chamber are not positioned on the same level as the first chamber.

4. The vapor chamber structure as claimed in claim 2 , wherein the second section is connected with a fourth section, the fourth section having the form of an elongated plate and being perpendicularly connected with the second section and extending to left and right sides of the second section, the fourth section having a fourth chamber, the capillary structure extending to the fourth chamber to be disposed on inner wall surface of the fourth chamber, the third section being connected with a fifth section, the fifth section having the form of an elongated plate and being perpendicularly connected with the third section and extending to left and right sides of the third section, the fifth section having a fifth chamber, the capillary structure extending to the fifth chamber to be disposed on inner wall surface of the fifth chamber.

5. The vapor chamber structure as claimed in claim 4 , wherein the first, second, third, fourth and fifth sections are not positioned on the same level.

6. The vapor chamber structure as claimed in claim 4 , wherein the main body has a sixth section, the sixth section having the form of an elongated plate, two ends of the sixth section being respectively perpendicularly connected with the first section and the fourth section, the sixth section having a sixth chamber, the capillary structure extending to the sixth chamber to be disposed on inner wall surface of the sixth chamber.

7. The vapor chamber structure as claimed in claim 6 , wherein the first, second, third, fourth, fifth and sixth chambers communicate with each other.

8. The vapor chamber structure as claimed in claim 6 , wherein a portion of the fourth section near a rear end thereof is perpendicularly bent to extend, multiple radiating fins being fitted on the extending portion of the fourth section.

9. The vapor chamber structure as claimed in claim 1 , wherein multiple radiating fins are disposed on one side of the first chamber.
