Description

Field of the invention

The present invention relates to an intermediate member for heat sinks and a heat sink, and more particularly to an intermediate member for heat sinks and a heat sink in which at least one or both sides of the upper and lower sides of a single intermediate member body for increasing the capillary force having the same surface structure or different surface structures is / are.

State of the art

Current vapor-liquid cycle heat sinks for heat dissipation primarily include heat pipes and vapor chambers. When used in a confined space, such. As with mobile devices or smartwatches, therefore, the overall structure of the heat pipe or the vapor chamber must be kept flat for the purpose of adaptation to the arrangement space of the application area.

In a vapor chamber or a heat pipe, primarily a capillary structure and a working fluid are provided inside the vacuum chamber. The heat transfer takes place by means of a two-phase transformation, ie. H. after heating, the working fluid in the vacuum chamber is evaporated and condensed. Therefore, the steam channel for vaporization and spreading and the capillary structure for condensing and returning the working liquid, together with the flat shape, have become a focal point for attaining improvements. However, the flat configuration reduces the space of the vacuum chamber and weakens the structural strength of the capillary structure and the outer plate. These are the most important tasks that need to be solved.

For vapor chambers and heat pipes, copper material is usually used. Copper has the properties of fast heat transfer and high ductility. Therefore, it is easy for copper plates or copper pipes, which have a flat design, to deformations. When deformation has occurred in the vapor chamber or the heat pipe, the vacuum chamber is compressed or collapsed, so that the filled working fluid is no longer able to carry out the transfer of heat by means of a vapor-liquid cycle.

Further, due to the reduction of the space of the vacuum chamber caused by the flat configuration, the selection of the capillary structure to be arranged in the vacuum chamber is another problem to be solved. Since sintering powder is more difficult to arrange in a narrow space, sintered powder is used in the industry as a flat mesh Capillary structure is used replaced. However, flat mesh must still be sintered to the outer panel or to the pipe wall so that the mesh in the chamber does not warp or slip. However, the narrowness in the vacuum chamber makes the sintering of the capillary structure and the chamber more difficult. After sintering, steam channels may have disappeared.

Further, when a conventional capillary structure formed by sintering or mesh fabric is arranged in a small space and deformed by compression, the flow distribution of the capillary structure can not be effectively controlled in the three-dimensional (axial and radial) directions, and further, gas in the capillary structure does not leak out can, whereby the resistance of the gas or the liquid can not be reduced, thus stopping the vapor-liquid cycle, so that the cooling of the contacting and serving for heat transfer or heat dissipation heat source can not be successfully performed, which may be due to Overheating caused crashes or leads to the occurrence of a fire chips. In the conventional capillary structure produced by sintering or mesh fabric, the heat flow structure for liquid-gas separation can not be established. In the Vapor Chamber, due to the opposite directions of flow of the vapor and liquid between the liquid and gas, bubbling can easily occur, increasing the resistance between the liquid and the gas.

The above defects are those most in need of improvement in the current shallow heat sinks.

Object of the invention
