Abstract

A vapor chamber structure includes a first plate body, a second plate body and a tubular body. The first plate body has a first extension section perpendicularly extending from a periphery of the first plate body. The second plate body has a second extension section perpendicularly extending from a periphery of the second plate body. The second extension section is fitted around the first extension section, whereby the first and second plate bodies are correspondingly mated with each other to form a closed chamber. The tubular body penetrates through the first and second extension sections in communication with the closed chamber. By means of the first and second extension sections normal to the first and second plate bodies, when the first and second plate bodies are connected, the arrangement space occupied by the peripheral void section of the vapor chamber is reduced.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a vapor chamber structure, and more particularly to a vapor chamber structure, which is free from any void section on the connection section of the vapor chamber.

2. Description of the Related Art

Please refer to FIG. 1, which is a sectional assembled view of a conventional vapor chamber structure. The conventional vapor chamber 2 has a first plate body 21 and a second plate body 22. The first plate body 21 has a first connection section 211. The first and second plate bodies 21, 22 are correspondingly mated with each other to together define a chamber 2 a. The peripheries of the first and second plate bodies 21, 22 are connected with each other by means of welding or diffusion bonding so as to connect the first and second plate bodies 21, 22 with each other and completely sealedly close the chamber 2 a.
After the two plate bodies of the conventional vapor chamber 2 are overlapped and mated with each other, a structure body with a closed vacuumed chamber for vapor-liquid circulation is formed. When connected, the outermost peripheral sections (the first connection section 211) of the first and second plate bodies 21, 22 are reserved as the sections for connecting the two plate bodies by means of diffusion bonding to close the chamber. After the sections are connected, a flange is formed as a void section without any vapor-liquid circulation effect. The void section will inevitably lead to increase of the total volume of the vapor chamber. In case of a limited use space, the peripheral void section of the vapor chamber will greatly discount the flexibility of arrangement of the vapor chamber.

SUMMARY OF THE INVENTION

It is therefore a primary object of the present invention to provide a vapor chamber structure, which is able to solve the problem of void section of the conventional vapor chamber.
To achieve the above and other objects, the vapor chamber structure of the present invention includes a first plate body, a second plate body and a tubular body.
The first plate body has a first plane face and a first extension section perpendicularly extending from a periphery of the first plane face. The first plane face and the first extension section together define a first receiving space. The second plate body has a second plane face and a second extension section perpendicularly extending from a periphery of the second plane face. The second plane face and the second extension section together define a second receiving space. The second extension section of the second plate body is correspondingly fitted around the first extension section, whereby the first and second plate bodies are correspondingly mated with each other to form a closed chamber. The tubular body penetrates through the first and second extension sections in communication with the first and second extension sections and the closed chamber.
By means of the vapor chamber structure of the present invention, the problem of void section of the conventional vapor chamber is solved. In addition, the total volume of the vapor chamber is minified so that the use and arrangement of the vapor chamber is more flexible.

Please refer to FIG. 9, which is a sectional assembled view of a seventh embodiment of the vapor chamber structure of the present invention. The seventh embodiment is partially identical to the first embodiment in structure and thus will not be repeatedly described hereinafter. The seventh embodiment is different from the first embodiment in that an auxiliary connection body 5 is fitted around the tubular body 13 and connected with the tubular body 13 and the second extension section 122 of the second plate body 12. The auxiliary connection body 5 serves to make the second connection end 1221 more securely connected with the outer circumference of the tubular body 13.
Please refer to FIG. 10, which is a sectional assembled view of an eighth embodiment of the vapor chamber structure of the present invention. The eighth embodiment is partially identical to the first embodiment in structure and thus will not be repeatedly described hereinafter. The eighth embodiment is different from the first embodiment in that a capillary structure layer 3 is disposed on the wall face of the closed chamber 1 a. The capillary structure layer 3 is selected from a group consisting of powder sintered body, fiber body, meshed body and channeled body. The closed chamber 1 a has at least one support body 4. The support body 4 has a first end 41 and a second end 42 respectively connected with the first and second plate bodies 11, 12. The capillary structure and the support body are not limited to be applied to this embodiment. The capillary structure and the support body of this embodiment are also applicable to the aforesaid embodiments.
The primary object of the present invention is to bend the connection sections (the first and second extension sections 112, 122) of the first and second plate bodies 11, 12 so that the connection sections are normal to the first and second plane faces 111, 121. The first and second extension sections 112, 122 are fitted and connected with each other. The contact sections of the first and second connection ends 1121, 1221 are connected by means of press fit to provide first-stage connection strength. Then, by means of welding or diffusion bonding, second-stage connection strength is provided to enhance the connection and sealing effect. Accordingly, the vapor chamber is prevented from leaking and kept vacuumed. Furthermore, the first and second extension sections 112, 122 are bent to be normal to the first and second plane faces 111, 121. In this case, the space occupied by the void section of the vapor chamber is reduced to eliminate the shortcoming of the conventional vapor chamber. Therefore, the flexible space for the arrangement of the vapor chamber is increased.
The way in which the tubular body 13 and the first and second connection ends 1121, 1221 are connected not only is able to enhance the connection strength and support strength between the tubular body 13 and the first and second plate bodies 11, 12, but also is able to avoid leakage and keep the vapor chamber vacuumed.
The present invention has been described with the above embodiments thereof and it is understood that many changes and modifications in such as the form or layout pattern or practicing step of the above embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
