Description

Technical Field

[0001] The utility model relates to the field of water-cooling and heat dissipation modules, in particular to a glue-injected integrally formed water-cooling and heat dissipation module. Background Art

[0002] The existing water cooling module has the following shortcomings:

[0003] 1. Since the heat dissipation body of the current water-cooled heat dissipation module is made of all-metal materials, manufacturers need to use machined metal processes, so they must use welding processes such as brazing or laser welding for assembly. However, the welding process has restrictions on materials and can only use the same material, which has certain limitations; the heat dissipation body and the fixed frame need to be further connected with bolts, making the process more complicated.

[0004] 2. After assembly using welding technology, each component is welded into an integrated structure. If water leakage occurs at a certain position during use, the entire structure can only be replaced.

[0005] 3. The water pipe joints are also brazed together, which is not conducive to replacement and has limitations on the specifications of water pipe accessories.

[0006] 4. Due to process limitations, the heat storage base uses a solid metal heat storage base, and the heat sink height can only be designed to be 4-5mm at most, which cannot further improve the heat dissipation performance.

[0007] 5. Due to processing problems, the inside of the water pipe joint is L-shaped and not smooth, which will cause water resistance. Utility Model Content

[0008] In order to overcome the above-mentioned defects of the prior art, the utility model provides a glue-injected one-piece water-cooling heat dissipation module.

[0009] The technical solution of this utility model is as follows:

[0010] The water-cooled heat dissipation module is formed by one-piece injection molding, including a heat storage base and an injection molded upper cover, wherein the interior of the injection molded upper cover is a hollow chamber, the heat storage base is sealed and connected to the bottom of the injection molded upper cover, and the heat sink arranged on the heat storage base is located in the hollow chamber;

[0011] The injection molded upper cover is provided with a water inlet and a water outlet, and the water inlet and the water outlet are both connected to the hollow chamber;

[0012] The injection-molded upper cover is composed of a fixed frame and a top cover plate, and the fixed frame and the top cover plate are an integral injection-molded structure; or the top cover plate and the fixed frame are injection-molded separately and then sealed and connected.

[0013] The interior of the heat storage base is a hollow structure, and the inner wall is provided with an anti-oxidation coating to prevent direct contact and oxidation between copper and water.

[0014] The heat storage base adopts a temperature averaging plate, and a capillary structure is arranged inside the temperature averaging plate, thereby increasing the heat conduction area.

[0015] The inner wall corner of the water pipe joint is arc-shaped.

[0016] The fixing frame is provided with a plurality of fixing bolts for connecting the heat dissipating device.

[0017] The top of the injection-molded upper cover is detachably provided with two water pipe joints, which are connected to the hollow chamber so that liquid can flow in the hollow chamber.

[0018] Technical effects and advantages of the utility model:

[0019] The structure is injection molded using a mature injection molding solution, without additional machining or surface treatment, and has high production efficiency; it also meets the requirements of low carbon and environmental protection;

[0020] Easy to mass produce, simple and easy to understand structure, high yield rate, suitable for large-scale mass production operations;

[0021] Due to the high yield rate and the absence of the need for additional testing methods or equipment and subsequent processing, the overall cost of the product is reduced, making it more competitive in the market. BRIEF DESCRIPTION OF THE DRAWINGS
