Soaking plate structure

Abstract

The invention relates to a soaking plate structure. The soaking plate structure comprises an upper shell plate and a lower shell plate which are buckled together, wherein a support structure is arranged between the upper shell plate and the lower shell plate; the support structure is coated with the upper shell plate and the lower shell plate; a lower surface of the upper shell plate is fixedly connected to an upper surface of the support structure; an upper surface of the lower shell plate is fixedly connected to a lower surface of the support structure; the support structure comprises a porous structure layer; the porous structure layer is made from a porous material; and the porous material has a pore density of 5-30ppi and a porosity of 80%-99%. The porous material with a low pore density and a high porosity is taken as the support structure of a soaking plate, and the structure is uniform in support point position distribution, high in density, reliable in support effect, free from influence on heat transfer performance of the soaking plate, capable of being used for manufacturing soaking plates with various shapes, simple to produce, low in cost, and suitable for batch production.

Description

technical field [0001] The invention relates to the field of heat transfer devices, in particular to a vapor chamber structure. Background technique [0002] The support structure of the existing vapor chamber usually adopts columns regularly arranged between the upper and lower shell plates to play a supporting role. Chinese patent applications CN102374808A and CN101566440B disclose a vapor chamber, which adopts opposite sides of a metal braided mesh to respectively abut against opposite sides of a housing for support. [0003] The problem that prior art exists is: [0004] 1. If the column support structure is used, when the column and the shell are integrally formed, the processing is difficult and the cost is high; when the column and the shell are independent structures, it is necessary to arrange the columns and make The process is more complicated. [0005] 2. If the support methods of Chinese patent applications CN102374808A and CN101566440B are used, since the ma...

[0004] 1. If the column support structure is used, when the column and the shell are integrally formed, the processing is difficult and the cost is high; when the column and the shell are independent structures, it is necessary to arrange the columns and make The process is more complicated

[0005] 2. If the support methods of Chinese patent applications CN102374808A and CN101566440B are used, since the maximum gap in the plane direction of the metal braid is less than or equal to the diameter of the braided copper wire, the steam channel in the plane direction is small, which is not conducive to steam diffusion. In order to increase the plane direction If there is a gap, the diameter of the copper wire must be increased, but this also increases the overall thickness of the woven wire mesh, which is not conducive to the production of vapor chambers with different thickness requirements.

In addition, the compressibility of the woven wire mesh is not good. In order to obtain a better supporting effect, it is required to strictly control the flattening accuracy of the vapor chamber, which puts forward higher requirements for processing.

For example: when the degree of flattening is not enough to make the woven wire mesh adhere to the upper and lower sides, the woven wire mesh cannot play a supporting role; when the flattening is excessive, the supporting point of the woven wire mesh is easy to damage the capillary liquid-absorbing core structure in contact with it, At the same time, it may cause uneven force on the shell plate, resulting in uneven surface
