Description

Technical Field

[0001] This utility model relates to the field of temperature equalization plate technology, specifically to an ultra-thin temperature equalization plate cover with a positioning groove. Background Technology

[0002] As is well known, an ultrathin vapor chamber is a passive heat dissipation device that utilizes the principle of phase change heat transfer (evaporation and condensation cycle) for two-dimensional efficient heat conduction. Its core objective is to rapidly and evenly diffuse the heat from point / area heat sources across the entire plate surface, thereby reducing the temperature of local hot spots and creating conditions for subsequent heat exchange through heat pipes, fins, or the outer shell.

[0003] A utility model patent with patent authorization announcement number CN219454785U discloses an ultrathin heat spreader. This ultrathin heat spreader includes a first cover plate, a second cover plate, a capillary layer, and support columns. The first and second cover plates are interlocked to form a sealed chamber. The capillary layer is attached to the inner end face of the first cover plate and includes an air passage and a copper mesh. Multiple support columns are provided; some support columns are positioned between the second cover plate and the copper mesh, while others are supported at one end by the second cover plate and at the other end through the air passage and supported by the first cover plate. Within the space enclosed by the capillary layer and the second cover plate, a steam channel is formed between adjacent support columns. Within the space enclosed by the air passage and the first cover plate, an auxiliary air passage is formed between adjacent support columns. This is the ultrathin heat spreader.

[0004] However, existing ultra-thin heat spreaders also have certain drawbacks. Although most existing ultra-thin heat spreaders are assembled by vacuum welding of upper and lower cover plates, the surface of the upper cover plate is relatively smooth and the overall structure is relatively simple, which makes it difficult to connect and assemble with subsequent equipment components. Utility Model Content

[0005] The purpose of this utility model is to provide an ultra-thin heat exchanger cover with a positioning groove, which solves the problem that although existing ultra-thin heat exchangers mostly use upper and lower cover plates for vacuum welding assembly, the surface of the upper cover plate is relatively smooth and the overall structure is relatively simple, which makes it difficult to connect and assemble with subsequent equipment parts.

By setting the thermally conductive silicone rod and the thermally conductive pad, the heat-conducting rod and the thermally conductive sheet can have good thermal conductivity.

[0011] Preferably, there are two capillary grooves, which are symmetrically distributed on the upper cover plate. The capillary grooves can be used to conduct heat quickly.

[0012] Preferably, four capillary grooves are provided, and the four capillary grooves are evenly distributed on the upper cover plate. Through the arrangement of the capillary grooves, heat can be quickly conducted.
