[0001] The utility model relates to the technical field of heat dissipation of commercial memory bars, in particular to a hollow thin-sheet metal heat sink. Background Art

[0002] The memory sticks in existing commercial computers, especially those in data centers, need to be cooled. The conventional heat sink is a C11000 copper heat sink. The heat sink is attached to one side of the memory stick to dissipate heat by utilizing the high heat dissipation coefficient of copper material.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2 As shown, the utility model provides a hollow thin-sheet metal heat sink, including a heat sink body 1 made of metal material, the heat sink body 1 is a hollow thin-walled structure, and a heat sink cavity is formed inside for high-pressure and high-speed heat dissipation liquid to flow; it also includes a water inlet 2 and a water outlet 3 arranged on both sides of the heat sink body 1 and respectively connected to the heat sink cavity.

[0024] It should be noted here that the high-pressure and high-speed heat dissipation liquid is realized by a pressure pump, and the high-pressure and high-speed heat dissipation liquid is used to pass quickly in the heat dissipation cavity, which not only greatly improves the heat dissipation effect and can quickly take out the heat to achieve heat dissipation, but also has the high-pressure and high-speed effect of the heat dissipation liquid, thereby providing sufficient pressure-bearing effect in the heat dissipation cavity, so that the thin-walled heat sink can withstand higher pressure. The inventor conducted a destructive test and found that the heat sink provided in this embodiment can withstand a maximum pressure of 50 kilograms.

[0025] The hollow thin-sheet metal heat sink provided by the utility model is arranged into a hollow structure to form a heat sink cavity, and then uses heat dissipation liquid for circulating cooling and heat dissipation, which can not only reduce the thickness of the heat sink and reduce the cost, but also greatly improve the heat dissipation effect.

[0026] Further, such as Figure 1 As shown, in this embodiment, the overall thickness of the heat sink body 1 is 2-2.4 mm, while the wall thickness of the heat sink body 1 is only 0.3-0.7 mm, and in this embodiment, the heat sink body 1 is integrally formed of stainless steel metal material.

[0027] It should be noted here that the improved heat sink is made of stainless steel material, and the processing method is the applicant's research and development after repeated experiments on the basis of scrapping more than 10 sets of molds. It uses a plastic mold for stainless steel metal sintering molding and adopts traditional processing methods. Since the wall of the heat sink is very thin and the overall thickness is small, it cannot be processed and formed using existing technology. It is not only easy to crack, but also has a large deformation. Therefore, based on repeated experiments, the applicant combines plastic molds to carry out processing of the heat sink in a similar way to plastic processing. Not only does it realize the processing and forming of thin-walled hollow heat sinks, but it also has good pressure bearing capacity and is not easy to deform.

[0028] Further, such as Figure 3 As shown, it also includes pressure-bearing ribs 4 arranged in the heat dissipation cavity to support the two side walls of the heat dissipation fin body 1.

[0029] It should be noted here that the pressure-bearing ribs 4 are arranged in multiple rows and columns, and the spacing and specifications can be adjusted as needed to meet different pressure-bearing requirements.

[0030] Furthermore, the cross section of the pressure-bearing rib 4 is square.

[0031] The overall pressure resistance of the heat sink is improved as much as possible through the dual effects of the pressure-bearing ribs 4 and the high-pressure and high-speed heat dissipation liquid.

[0032] Further, such as Figure 1 As shown, the heat sink body 1 is a T-shaped structure, which is adapted to the shape of the memory stick; the water inlet 2 and the water outlet 3 are respectively arranged at the two ends of the large head section 6 of the heat sink body 1.

[0033] Furthermore, the middle position of one side of the heat sink body 1 is recessed downward to form an escape groove 5. The escape groove 5 is used to escape the raised part on the memory stick. The depth of the escape groove 5 is 0.2 mm.

[0034] Although the setting of the avoidance groove 5 causes this part of the heat sink to be concave inward, the inner cavity specifications are not reduced, but the wall thickness of the heat sink here is thinned, thereby forming a wall thickness of the heat sink body 1 corresponding to the avoidance groove 5 of 0.3-0.5mm, that is, the wall thickness of the heat sink body 1 without the avoidance groove 5 is 0.2mm thicker than the wall thickness at the avoidance groove 5.
