Abstract

A vapor chamber structure having a hollow thin flat housing and a composite material wick layer accommodated therein is provided in the present disclosure. The composite material wick layer is a metal mesh having multiple braided metal wires. Each metal wire of the composite material wick layer is a steel wire coated a cover layer. Thereby, when a steel material is drawn into the steel wire, a diameter of the steel wire could be reduced and the steel wire could be reinforced. Therefore, the steel wire could be braided into a more compact mesh suitable for a thin flat vapor chamber.

Description

Structure improvement of uniform temperature plate

The present invention is related to a vacuum heat transfer element, especially an improvement in the structure of a uniform temperature plate.

According to this, due to the continuous enhancement of the computing power of various electronic products, at the same time with the generation of heat dissipation problems. Therefore, nowadays, whether it is a uniform temperature plate or a plate heat pipe, it is an indispensable heat dissipation element.

However, as electronic products are also moving towards thin and light design, the uniform temperature plate or plate heat pipe is bound to be thinner. However, under the continued thinning, the capillary function of the internal capillary tissue has been affected. If it is no longer possible to find thinner materials as the capillary tissue, it is difficult to achieve the demand for thinner. Plate heat pipes cannot adapt to the thinning trend of electronic products.

In view of this, in order to improve and solve the above-mentioned shortcomings, the inventor of the present invention made great efforts to research and cooperate with the application of scientific theory, and finally proposed an invention with reasonable design and effective improvement of the above-mentioned shortcomings.

The main purpose of the present invention is to provide an improved structure of the uniform temperature plate, which uses steel wires to form the capillary structure in the uniform temperature plate, so that when the steel is drawn into a wire shape, the wire diameter obtained is relatively thin and difficult Breaking can be used to woven into a mesh to obtain a woven mesh with a finer mesh, which can then be set in a thinner uniform temperature plate.

Another object of the present invention is to provide an improvement in the structure of the uniform temperature plate, which is provided with a coating layer on the outside of the steel wire, so as to provide that the steel wire is installed in the uniform temperature plate not to be corroded due to the influence of the working fluid.

In order to achieve the above-mentioned object, the present invention provides an improved structure of a uniform temperature plate, which includes a thin plate housing with a hollow inside and a composite capillary layer arranged in the thin plate housing; wherein the composite capillary layer is a The metal woven mesh is formed by weaving a plurality of metal wires, and each metal wire of the composite capillary layer is a steel wire with a covering layer outside it.

The present invention provides an improved structure of a uniform temperature plate, which includes a thin-plate shell 1 and a composite capillary layer 2 arranged in the thin-plate shell 1; wherein:

The thin plate housing 1 is hollow and can be made of materials such as copper or aluminum, and the thin plate housing 1 can be formed by a first plate 10 and a second plate 11 covering each other. In the first embodiment of the present invention, the first plate 10 has a continuous first sealing edge 100 formed on its periphery, and is surrounded by the first plate 10 and the first sealing edge 100 The first recessed space 101 formed is covered by the second plate 11 on the first sealing edge 100 to close the first recessed space 101 to form the thin-plate housing 1. In addition, the first recessed space 101 can be etched to form the first recessed space 101 by recessing a surface of the first plate 10 inwardly by means such as etching, and can be formed in the first recessed space 101. The unetched part is reserved in the entrance space 101 to form a plurality of first support portions 102, so that the second plate 11 can close the first recessed space 101 and be stacked on the first plate 10. The first supporting parts 102 are pressed against the inner surface of the second plate 11 to serve as a supporting structure.

The composite capillary layer 2 is arranged in the above-mentioned thin plate housing 1; and in the first embodiment of the present invention, the composite capillary layer 2 is arranged in the first recessed space 101. The present invention mainly lies in that the composite material capillary layer 2 is a woven metal mesh and is formed by weaving a plurality of metal wires; wherein each metal wire of the composite material capillary layer 2 is a steel wire and a coating layer 21 is provided outside of the composite material capillary layer 2. When the steel is drawn into a wire shape, the obtained wire diameter is thin and not easy to break, and it can be used to knit into a mesh to obtain a woven mesh with a finer mesh, which can then be set on the thinner plate shell. In the body 1, while maintaining the capillary force that the composite capillary layer 2 should have. In addition, the coating layer 21 outside the steel wire can be formed by coating. The material of the coating can be titanium, and the coating can be coated before each steel wire is woven into the capillary layer 2 of the woven mesh. Layer 21; or after the steel wires are woven into the capillary layer 2 of the woven mesh, the capillary layer 2 is then plated with the covering layer 21. In order to ensure that the composite capillary layer 2 composed of steel wire provides its capillary force, it will not be corroded by the working fluid and has the effect of preventing rust.

2 again, the present invention can also be provided on the composite capillary layer 2 with a plurality of positioning holes 20 corresponding to each first support portion 102, so that the composite capillary layer 2 can be fixed to the first support portion 102. The first recessed space 101 of a plate 10 is close to the inner surface of the first plate 10.

Therefore, the structure improvement of the uniform temperature plate of the present invention can be obtained by the above-mentioned structure composition.

Furthermore, as shown in FIGS. 3 and 4, in the second embodiment of the present invention, the second plate 11 of the thin-plate housing 1 may also have a second seal formed on its periphery and formed continuously. Rim 110, and the second recessed space 111 formed by the second plate 11 and the second sealing rim 110, and when it is covered with the first plate 10, it penetrates the first and second plates 10 11, the first and second sealing edges 100, 110 are relatively tightly closed to close the first and second recessed spaces 101, 111, so as to serve as other feasible implementation aspects of the thin plate housing 1. In addition, the second recessed space 111 can also be etched to form the second recessed space 111 by recessing a surface of the second plate 11 inwardly by means such as etching. The unetched part is reserved in the inlet space 111 to form a plurality of second supporting parts 112, so that when the first plate 10 is covered, the first supporting parts 102 and the second supporting parts 112 can be pressed against each other And each other can be used as a supporting structure.
