Description

Technical Field

[0001] The utility model relates to the technical field of vapor chambers, in particular to a vapor chamber with an integrated structure. Background Art

[0002] The heat spreader is a vacuum cavity with a microstructured inner wall, usually made of copper. When heat is transferred from the heat source to the evaporation zone, the coolant in the cavity begins to vaporize after being heated in a low vacuum environment. At this time, it absorbs heat energy and expands rapidly in volume. The gas phase cooling medium quickly fills the entire cavity. When the gas phase working medium contacts a relatively cold area, condensation occurs. The accumulated heat during evaporation is released through the condensation phenomenon, and the condensed coolant returns to the evaporation heat source through the microstructured capillary channels. This operation will be repeated in the cavity.

[0003] For example, Chinese patent application No. 202220058103.3 relates to an ultra-thin flexible vapor chamber, which has the feature of being ultra-thin and uses a metal-polymer composite film combined with a secondary external packaging solution to ensure the flexible functional characteristics of the vapor chamber and improve the technical problem of vapor chamber degradation or even failure caused by water and oxygen penetration in the polymer matrix vapor chamber;

[0004] In the above scheme, the heat spreader releases heat through the evaporation of liquid and then condensation into liquid, over and over again. During long-term operation, water vapor is in the middle cavity of the heat spreader, so the temperature in the cavity is the highest. If the heat in the middle part can be dissipated, the heat dissipation effect of the heat spreader will be improved. In order to solve the above problems, we designed a heat spreader with an integrated structure. Utility Model Content

[0028] See also Figure 1-3 The plate body 1 and the plurality of heat dissipation fins 7 are integrally processed and have the characteristics of small thermal resistance and high heat transfer efficiency.

[0029] See also Figure 1-3 The plate body 1 is made of steel, which can increase the strength of the heat spreader, and the steel is light in weight, which reduces the weight of the heat spreader overall.

[0030] See also Figure 1-3 The water pipe 10 located in the plate body 1 is arranged in an integrated curved shape, and the water pipe 10 is passed through and wound between the multiple reinforcement columns 3, which can increase the running path of the water pipe 10 and improve the heat exchange effect.

[0033] The working principle of the utility model is as follows: the plate body 1 is made of steel, which can increase the strength of the heat spreader, and the steel is light in weight, which reduces the weight of the heat spreader overall. The setting of the copper plate 4 can well prevent the liquid from reacting with the steel material between the plate body 1 to produce non-condensable gas.
