Example

[0024]The detailed description and technical contents of the present invention will be explained with reference to the accompanying drawings. However, the drawings are illustrative only but not used to limit the present invention.

[0025]Please refer to FIGS. 1 and 2. The present invention provides a vapor chamber 1 with a wick structure of different thickness, which is constituted of a casing 10, a working fluid 20, a wick structure 30 and a supporting body 40.

[0026]The casing 10 is made of copper or aluminum. The interior of the casing 10 is formed with a chamber 11.

[0027]The working fluid 20 is filled in the chamber 11. The working fluid 20 can be pure water, alcohol, methanol, ethanol or propyl alcohol, but it is not limited thereto.

[0028]The wick structure 30 is adhered to the inner wall of the chamber 11. The wick structure 30 has a first wick section 31 and a second wick section 32 extending from the first wick section 31. The thickness of the wick section 31 is larger than tha...

Abstract

A vapor chamber with a wick structure of different thickness includes a casing, a wick structure, a supporting body and a working fluid. The casing has a chamber. The wick structure is adhered to the inner wall of the chamber. The wick structure has a first wick section and a second wick section extending from the first wick structure. The thickness of the first wick section is larger than that of the second wick section. The supporting body is received within the wick structure. The working fluid is filled within the chamber. Via the above arrangement, the heat-conducting efficiency can be increased while the cost can be reduced.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a vapor chamber and a die for forming the vapor chamber, and in particular to a vapor chamber with a wick structure of different thickness and a die for forming the vapor chamber.[0003]2. Description of Prior Art[0004]Since vapor chambers have many advantageous features such as large heat-conducting capacity, high heat-transferring rate, light weight, simple structure, versatility, capability of transferring large amount of heat without consuming any electricity, low price and etc., they are widely used in dissipating the heat generated by electronic elements. Via the vapor chamber, the heat generated by electronic elements can be dissipated quickly, thereby overcoming the heat accumulation occurring in the electronic elements at current stage.[0005]The conventional vapor chamber includes a casing, a wick structure, a supporting body and a working fluid. The casing has a chamber. The wic...
