Therefore, the heat dissipation problem is important to maintain the life and reliability of the electronic product. In order to quickly transfer heat from a chip on a circuit board of an electronic product to a heat sink, the chip is generally directly attached to the heat sink. Because of the existence of tolerance between the chip and the radiator, a larger gap needs to be arranged, and at present, an interface material is generally used for directly filling the gap, but the interface material is generally small in heat conduction coefficient, so that heat on the chip is difficult to conduct effectively, and then the overtemperature risk exists. And the heat conduction structure for heat dissipation of the heating element of the electronic product at present can only conduct vertical heat dissipation, so that heat dissipation is uneven, and normal operation and service life of the heating element are affected. In addition, the existing heat conduction structure cannot be in close contact with the heating element, and the problem of poor heat dissipation effect can be caused.
The Vapor Chamber (VC) is also called a vapor chamber, can be used for heat dissipation of electronic products such as smart phones, tablet computers, high-grade light and thin notebook computers, wearable electronic devices and the like, has the advantage of rapid heat conduction, and can transfer heat from a hot spot to the whole surface for heat dissipation. However, the size of the temperature equalization plate in the prior art is usually fixed, assembly errors may exist during assembly, and pressure cannot be provided so that the temperature equalization plate is in close enough contact with the chip and the shell, and heat conduction efficiency needs to be further improved.

Detailed Description
In order to further explain the technical means adopted by the present utility model and the effects thereof, the following detailed description is given with reference to the preferred embodiments of the present utility model and the accompanying drawings.
Referring to fig. 1, 2 and 3, the present utility model provides a soaking plate, which includes a bottom shell 1, a cover plate 3, two capillary structure layers 5, a plurality of elastic supporting members 7, and a condensate 9, wherein the cover plate 3 is covered on the bottom shell 1 to form a chamber 10, and the condensate 9 is located in the chamber 10. Two capillary structure layers 5 are located in the chamber 10 and are respectively arranged on the inner surfaces of the bottom shell 1 and the cover plate 3. The plurality of elastic supporting members 7 are located in the chamber 10, the two capillary structure layers 5 are respectively provided with a plurality of through holes 51 corresponding to the plurality of elastic supporting members 7, and two ends of each elastic supporting member 7 respectively pass through the corresponding through holes 51 and respectively prop against the inner surfaces of the bottom shell 1 and the cover plate 3.
Specifically, the bottom shell 1 includes a bottom plate 12 and a plurality of side walls 14 connected to the bottom plate 12, and the cross-sectional shape of the side walls 14 is wavy. One of the two wicking layers 5 is provided on the inner surface of the bottom plate 12. Further, the two capillary structure layers 5 are bonded to the inner surfaces of the bottom plate 12 and the cover plate 3 by welding, respectively, or the two capillary structure layers 5 are bonded to the inner surfaces of the bottom plate 12 and the cover plate 3 by heat conductive adhesive, respectively.

Specifically, the materials of the bottom case 1 and the cover plate 3 are metals, preferably pure copper or copper alloy.
The working principle of the vapor chamber A of the utility model is as follows: the heat emitted by the heat generating device C is transferred to the outer surface of the soaking plate a (for example, the outer surface of the cover plate 3) through direct contact with the soaking plate a, and the capillary structure layer 5 positioned on the inner surface of the cover plate 3 transfers the heat to condensate 9 (for example, water) in the chamber 10, and the condensate 9 absorbs the heat to evaporate into gas, thereby taking away the heat. Because of the latent heat of the condensed gas (e.g. water vapor), the hot gas in the chamber 10 will move along the chamber 10 to the inner wall (the capillary layer 5 on the inner surface of the bottom plate 12) with a lower temperature, and will liquefy and release heat energy, and these condensed liquids 9 will dissipate heat through the capillary layer 5 on the inner surface of the bottom plate 12, and because the distance between the two capillary layers 5 will not be too large, there will be a certain capillary force between them, and after the heat dissipation of the condensed liquid 9 will return to the capillary layer 5 on the inner surface of the cover plate 3 through the capillary force, and will absorb heat again, and circulate in this way, so as to derive the heat emitted by the heat generating device C.
When the soaking plate a is used, as shown in fig. 4, the soaking plate a can be placed between the casing B and the heating device C, and because the elastic supporting piece 7 can be compressed, the soaking plate a can be stressed and deformed, and the wavy side wall 14 is also favorable for bearing a certain pressure, so that the pressure can be properly applied to the casing B and the heating device C, so that the soaking plate a can be in closer contact with the casing B and the heating device C, the heat conduction efficiency can be improved, and the assembly error can be reduced.
