The uniform temperature plate is used to fix part of the shell to a heat-generating object (such as the central processing unit of a computer), and the other part of the shell is affected by a heat-dissipating object (such as a fan), so that the working fluid is quickly evaporated by heat and condensed by cooling , and then quickly generate heat dissipation effect on the heat-generating object.

Some of the chambers of some chambers will be provided with a plurality of support structures connecting the inner top surface and the inner bottom surface, such as those provided by the patent case of my country’s patent publication No. 201300717. These several support structures are used to avoid the The outer surface of the shell is concaved inwardly during vacuuming, so that the shell can be fixed on the heating object in surface contact to improve the heat dissipation efficiency.

However, the supporting structure of the temperature chamber provided by the above-mentioned patent is difficult to be quickly formed by stamping, and the several supporting structures make the shell of the temperature chamber need to be made of a thicker metal plate, which not only costs a lot, but also weighs It is also relatively large. For today's lightweight electronic products, the added weight of the vapor chamber due to the several support structures is enough to have a considerable impact on the weight reduction of electronic products. In addition, the capillary structure of the vapor chamber provided by the aforementioned patent completely covers the inner top surface, the inner bottom surface of the shell and the several support structures, and the metal material that can produce capillary phenomenon required is less than that of the uniform plate without support structures. There are more warm plates, so the several supporting structures also cause the cost and weight of the capillary structure of the vapor chamber to be high.

The applicant first explains here that in the embodiments and drawings to be described below, the same reference numerals denote the same or similar components or structural features.

Please refer to FIG. 1 and FIG. 2 , the vapor chamber 10 with a support structure provided by a first preferred embodiment of the present invention includes a shell 20 and a capillary structure 30 .

The shell 20 is a flat container made of a metal plate (such as copper plate), which includes a square first plate body 21 and a second plate body 22 with a large area, and is connected to the first plate body 21 and the second board 22 and the four side boards 23 with smaller area, the several boards 21, 22, 23 define a closed accommodating space 24, and the accommodating space 24 accommodates a few The working fluid (not shown in the figure) is evacuated, and the working fluid is a material whose boiling point matches the working temperature of the vapor chamber 10 , such as pure water. In this embodiment, the several side plates 23 are integrally connected to the outer periphery of the second plate 22 to form a cover together, but the shell 20 is not limited thereto, as long as it can form a closed The accommodating space 24 gets final product.

The first plate body 21 and the second plate body 22 can respectively define an outer surface 211 , 221 and an inner surface 212 , 222 , and the two inner surfaces 212 , 222 are opposite to each other. Wherein, the second plate body 22 is substantially a flat plate, that is, its inner and outer surfaces 221, 222 are substantially plane; the first plate body 21 is a structural reinforcing plate with a plurality of supporting structures 213, the Several support structures 213 are recessed on the outer surface 211 and protrude on the inner surface 212, so that the outer surface 211 has a flat portion 211a, and a plurality of recessed portions 211b formed by the plurality of support structures 213, and the inner surface The surface 212 has a flat portion 212a, and a plurality of protruding portions 212b formed by the plurality of supporting structures 213, and the plurality of concave portions 211b correspond to the positions of the plurality of protruding portions 212b.
