Abstract

A vapor chamber structure including a main vapor chamber, at least one heat dissipation structure, and a plurality of metal blocks is provided. The main vapor chamber includes an upper plate and a lower plate. The main vapor chamber further includes a first cavity formed between the upper plate and the lower plate. The heat dissipation structure is located on an outer surface of the upper plate and fluidly connected to the first cavity of the main vapor chamber. The metal blocks are disposed in the first cavity.

First claim

What is claimed is:

1 . A vapor chamber structure, comprising:
a main vapor chamber comprising an upper plate, a lower plate and a first cavity located between the upper plate and the lower plate; and at least one heat dissipation structure disposed on an outer surface of the upper plate and fluidly connected to the first cavity of the main vapor chamber; and a plurality of metal blocks disposed in the first cavity.

2 . The vapor chamber structure of claim 1 , wherein the metal blocks disposed on the lower plate and a steam channel is formed between the metal blocks and the upper plate.

3 . The vapor chamber structure of claim 2 , wherein one of the metal blocks is extended to two opposite ends of the first cavity to prevent working fluids in two opposite areas of the first cavity from flowing into each other.

4 . The vapor chamber structure of claim 1 , further comprising a capillary structure located in the first cavity and disposed on the lower plate, wherein the capillary structure contacts the metal blocks.

5 . The vapor chamber structure of claim 1 , wherein the at least one heat dissipation structure comprises:
at least one auxiliary vapor chamber disposed on the outer surface of the upper plate and fluidly connected to the first cavity of the main vapor chamber; and at least one heat pipe disposed on the outer surface and fluidly connected to the first cavity of the main vapor chamber.

6 . The vapor chamber structure of claim 1 , wherein a quantity of the at least one auxiliary vapor chamber is multiple, a quantity of the at least one heat pipe is multiple, the auxiliary vapor chambers are spaced apart from each other, and the heat pipes are spaced apart from each other.

7 . The vapor chamber structure of claim 6 , wherein the outer surface is extended along a first direction and a second direction, the auxiliary vapor chambers and the heat pipes are extended along a third direction, the first direction is perpendicular to the second direction, and the third direction is different from any combination direction of the first direction and the second direction.

8 . The vapor chamber structure of claim 7 , wherein a first height of the auxiliary vapor chambers relative to the outer surface and along the third direction is lower than a heat pipe height of the heat pipes relative to the outer surface and along the third direction.

9 . The vapor chamber structure of claim 7 , wherein the heat pipes comprise:
at least one first type heat pipe extending toward the third direction; and at least one second type heat pipe, a first portion of the second type heat pipe extending toward the third direction, a first end of the first portion contacting the outer surface, a second portion of the second type heat pipe extending toward the second direction, the second portion being connected to a second end, opposite to the first end, of the first portion.

10 . The vapor chamber structure of claim 9 , wherein a quantity of the at least one first type heat pipe is multiple, a quantity of the at least one second type heat pipe is multiple, the first type heat pipe and the auxiliary vapor chamber are alternately arranged along the second direction.

11 . The vapor chamber structure of claim 10 , wherein the second type heat pipes are located between a portion of the auxiliary vapor chambers and another portion of the auxiliary vapor chambers, and no auxiliary vapor chamber is located between the second type heat pipes along the first direction.

12 . The vapor chamber structure of claim 6 , wherein each of the auxiliary vapor chambers comprises a second cavity, each of the heat pipes comprises a hollow portion, and the second cavity and the hollow portion are fluidly connected to the first cavity.

13 . The vapor chamber structure of claim 12 , wherein one of the metal blocks separates two adjacent heat pipes of the heat pipes, or one adjacent auxiliary vapor chamber of the auxiliary vapor chambers and one adjacent heat pipe of the heat pipes when the auxiliary vapor chambers, the heat pipes and the metal blocks are projected vertically onto the outer surface of the main vapor chamber.
