Problems solved by technology

That is to say, under the premise that the capillary structure has sufficient thickness, the strength of the capillary structure is still good, and it will not be broken during the assembly process; however, with the development of thinner vapor chamber , the thickness of the capillary structure also needs to be further reduced, thus facing the problem that the strength of the capillary structure is insufficient and fragile, so it is necessary to improve

Abstract

The invention provides a temperature-uniforming plate and a capillary sheet thereof, which are used for solving the problem that the existing temperature-uniforming plate is difficult to thin because the capillary structure is easy to break. The temperature-uniforming plate of the present invention comprises: a housing having a heat absorbing sheet and a heat releasing sheet which are arranged opposite to each other, the housing having a closed space inside; a working fluid which is filled in the closed space; a capillary sheet which is located in the closed space and makes contact with the working fluid, the capillary sheet is formed by sintering a mixed material, and the mixed material comprises at least two kinds of heat conduction particles with different lengths.

Description

technical field [0001] The invention relates to an article that can help electronic products dissipate heat, in particular to a uniform temperature plate and capillary sheets thereof. Background technique [0002] With the advancement of the technology industry, today's electronic products such as computers and mobile phones not only have excellent performance, but also have been moving towards a thinner and lighter trend; The temperature of the product increases, which increases the thermal failure rate and wear rate of electronic products. [0003] For this reason, there is currently an existing vapor chamber, which can be installed at the heat source of the electronic product to help eliminate the waste heat generated when the electronic product is in operation. Specifically, the conventional temperature chamber has a stamped metal shell, the metal shell has a capillary structure inside and is filled with working fluid, the metal shell can absorb heat energy from the hea...
