Description

Technical Field

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

[0002] The heat spreader is a vacuum cavity with a microstructure on the 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.

[0003] The upper and lower cover plates of some traditional heat spreaders are mostly butt-jointed together in a flat surface and then fixed by welding at the side. Although this structure can ensure the normal use of the heat spreader, the side connection position is relatively easy to be damaged. Once the welding position is damaged, it will directly lead to internal leakage, affecting the normal use of the heat spreader. The structural durability is not strong. At the same time, some traditional heat spreaders rely on the top of the heat spreader to dissipate heat naturally when conducting heat. When the heat dissipation requirements are high, the heat dissipation capacity is insufficient. Utility Model Content
