1. Field of the Invention
The present invention generally relates to a supporting structure, in particular, to a supporting structure for vapor chamber and a vapor chamber.
2. Description of Prior Art
Following continuous promotion in computing speed, more and more heat is generated in a computer's CPU. Thus, a cooling device comprised of aluminum-extruding cooler and fan has already been unable to satisfy the using requirement of current CPU. So, some relative industries subsequently develop heat pipe and vapor chamber, both of which have a higher heat-transferring performance. A cooler integrated with heat pipe or vapor chamber can effectively solve the cooling problem currently existed. Besides, since a vapor chamber is directly attached to heating electronic element with large contacting area, it attracts many relative industries to devote more efforts into the R&D work of this kind of vapor chamber.
As shown in
According to above prior art, the supporting structure is abutted against the capillary wick 30a with an intention to make the inner wall faces of the casing 10a tightly inter-contacted with the capillary wick 30. However, after being heated, the working fluid 20a is changed into a vapor phase from a liquid phase, then moved toward two sides of the plate along the wave channels of the support 40a, and finally transmitted into the above capillary wick 30a to achieve a heat-transferring mechanism. Since the transporting route of the vaporized working fluid is too long, the heat-transferring performance is very poor. In addition, because the support 40a is configured as a stripe shape to be abutted against the capillary wick 30a, most part of the capillary wick 30a is not abutted by the support 40a and a falling or collapsing phenomenon easily occurs due to the long supporting span. All these drawbacks are needed to be overcome urgently.
Accordingly, aiming to solving the aforementioned shortcomings, after a substantially devoted study, in cooperation with the application of relatively academic principles, the inventor has at last proposed the present invention “vapor chamber and supporting structure thereof” that are designed reasonably to possess the capability to improve the prior arts significantly.
The invention is mainly to provide a vapor chamber and a supporting structure thereof, in which the interspacing arrangement of the channels with the corrugated pieces arranged therein not only can make the capillary wick uniformly abutted against the inner wall faces of the casing to enhance the tightly contacting effect, but also can increase the vaporization amount of the working fluid to accelerate the heat-transferring speed and further boost the heat-conducting performance of the vapor chamber.
Secondly, the invention is to provide a vapor chamber, including a casing, a working fluid, a capillary wick, and a supporting structure, in which the casing has a hollow chamber; the working fluid is injected into the hollow chamber; the capillary wick is distributed in the hollow chamber; the supporting structure is accommodated in the capillary wick, including a plate, on which a plurality of channels are interspaced at equal intervals and are arranged by corresponding to each other, in each of which a corrugated piece is configured, top and bottom faces of which are respectively abutted against the capillary wick in a way, such that the capillary wick are tightly contacted with the inner wall faces of the casing.
Thirdly, the invention is to provide a supporting structure of vapor chamber, the vapor chamber including a casing, in which a capillary wick and a supporting structure are accommodated. The supporting structure includes a plate, on which a plurality of channels are disposed at equal intervals and arranged by corresponding to each other. A corrugated piece is formed in each channel and upper and lower sides of the corrugated piece are respectively abutted against the capillary wick, making the capillary wick and inner wall faces of the casing tightly contacted to each other.
The features of the invention believed to be novel are set forth with particularity in the appended claims. The invention itself, however, may be best understood by reference to the following detailed description of the invention, which describes an exemplary embodiment of the invention, taken in conjunction with the accompanying drawings, in which:
In cooperation with attached drawings, the technical contents and detailed description of the invention are described thereinafter according to a preferable embodiment, being not used to limit its executing scope. Any equivalent variation and modification made according to appended claims is all covered by the claims claimed by the present invention.

In this case, the supporting structure 40 includes a rectangular plate 41, which is made of metal materials with highly structural strength, and on which a plurality of channels 42 are arranged at equal intervals and corresponding to each other, and a separating plate 43 is formed between two adjacent channels 42. Furthermore, a first corrugated piece 44 and a second corrugated piece 45 are respectively configured in the channel 42. The first corrugated piece 44 is comprised of a crest section 441 higher than the top face of the plate 41 and two trough sections 442 respectively connected to the crest section 441 and lower than the bottom face of the plate 41. In addition, followed the first corrugated piece 44, the second corrugated piece 45 is comprised of two crest sections 451 higher than the top face of the plate 41 and a trough section 452 connected to each crest section 451 and lower than the bottom face of the plate 41. In addition, the crest sections 441, 451 of any two adjacent corrugated pieces 44, 45 are not adjacent to each other. In this case, the crest section 441 of the first corrugated piece 44 is just corresponded to the trough section 452 of the second corrugated piece 45, while the two trough sections 442 of the first corrugated piece 44 are just corresponded to the two crest sections 451 of the second corrugated piece 45.

According to the supporting structure 40 of the invention, since of the interspacing arrangement of each channel 42 and the disposition of the corrugated pieces 44, 45, not only the capillary wick can be uniformly abutted against and contacted to the inner wall faces of the casing 10 to enhance the tightly contacting effect between the capillary wick 30 and the inner wall faces of the casing 10, but also it is possible to increase the vaporization amount of the vapor chamber, accelerate the heat-transferring speed, and ultimately boost the heat-conducting performance.
Summarizing aforementioned description, the invention is a novel structure for supporting a vapor chamber indeed, which may positively reach the expected usage objective for solving the drawbacks of the prior arts, and which extremely possesses the innovation and progressiveness to completely fulfill the applying merits of new type patent, according to which the invention is thereby applied. Please examine the application carefully and grant it as a formal patent for protecting the rights of the inventor.
Moreover, the aforementioned description is only a preferable embodiment according to the present invention, being not used to limit the patent scope of the invention, so equivalently structural variation made to the contents of the present invention, for example, description and drawings, is all covered by the claims claimed thereinafter.
