[0021] 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.
[0022] like Figure 1As shown, the utility model provides a high-pressure resistant heat dissipation fin 2 reinforcement structure. It should be noted here that the heat dissipation fins 2 are located on the heat dissipation plate 1, and there are heat dissipation channels between the heat dissipation fins 2. In order to achieve water cooling, a top plate is also provided on the top of the heat dissipation fins 2 to cover the heat dissipation fins 2, thereby forming a closed chamber between the heat dissipation plate 1, the heat dissipation fins 2 and the top plate, and then a circulating cooling medium is supplied to the chamber via a water inlet on the top plate to achieve water cooling. The heat exchange medium has a certain flow rate and pressure. When passing through the heat dissipation fins 2, due to the small specifications of the fins, the pressure bearing capacity is not strong, and it is easy to tip over, deform and other problems, which leads to the blocking of the heat dissipation channel. In order to solve this problem, the utility model provides a reinforcement structure for improving the strength of the heat dissipation fins 2.
[0023] Specifically, in this embodiment, the reinforcement structure includes a retaining wall 3, a cover plate 4 and a protrusion 5; wherein:
[0024] The retaining wall 3 is arranged on two opposite sides of the heat dissipation fin 2 to avoid the heat dissipation flow channel;
[0025] The cover plate 4 is pressed on the top of the heat dissipation fins 2 and is fixedly connected to the heat dissipation fins 2 and the retaining wall 3 respectively;
[0026] The protrusion 5 is arranged on the cover plate 4 for fixed connection with the top plate;
[0027] A through opening 8 is provided on the cover plate 4, and the through opening 8 is arranged opposite to the water inlet on the top plate.
[0028] The utility model provides a high-pressure resistant heat dissipation fin 2 reinforcement structure, including a retaining wall 3, a cover plate 4 and a protrusion 5. The retaining wall 3 is arranged on both sides of the heat dissipation fin 2, the cover plate 4 is arranged on the top of the retaining wall 3, and the protrusion 5 is arranged on the cover plate 4 to realize welding among the three. After the protrusion 5 is welded to the top plate, the heat dissipation fin 2 can withstand the pressure reinforcement, the heat dissipation fin 2 is not easy to tilt or fall over, and can withstand higher heat dissipation fluid pressure and flow rate.
[0029] As an optional implementation of the utility model, in order to ensure stable connection and reduce the volume of the reinforcement structure, a downwardly recessed notch 6 is provided on the retaining wall 3; a connecting block 7 is provided at a corresponding position on the cover plate 4; and the connecting block 7 is welded in the notch 6.
[0030] Through this structure, the retaining wall 3 and the cover plate 4 can be conveniently connected while reducing the height of the entire reinforcement structure. That is to say, the connection between the retaining wall 3 and the cover plate 4 is achieved without having to be set very high, and this connection structure is more stable. The connecting block 7 first utilizes a snap-on structure in the notch 6, and then is welded to achieve a double connection effect. The connection is more stable and can also prevent the cover plate 4 from moving in two degrees of freedom horizontally relative to the retaining wall 3.
[0031] As an optional embodiment of the present invention, the notches 6 on each retaining wall 3 are respectively located on both sides of the through opening 8. This structural setting is also to further improve the connection strength and achieve the limit in the horizontal plane.
[0032] As an optional implementation of the present invention, the bottom of the cover plate 4 is attached to the top of the heat dissipation fins 2 and is welded to the heat dissipation fins 2 .
[0033] As an optional embodiment of the utility model, the top of the retaining wall 3 is also provided with a folding edge 9 that is bent inward and presses the edge of the cover plate 4. The setting of the folding edge 9 further ensures that the cover plate 4 will not be displaced in the vertical direction, and the connection strength is further improved on the basis of the welding connection.
[0034] As an optional implementation of the present utility model, the number of the convex points 5 is several and they are arranged in a uniform array, such as Figure 1 Only one embodiment is illustrated. Of course, other arrangements and structures can also be adopted.
[0035] As an optional embodiment of the utility model, the protrusion 5 is a cylindrical protrusion 5. Of course, the protrusion 5 can also be set to other shapes, such as rectangular, square, triangular, trapezoidal, and of course the protrusion 5 can also be set to a hemispherical structure. However, in order to ensure the welding strength with the top plate and ensure a good connection effect, the top surface of the protrusion 5 is preferably a plane with a certain contact area.
[0036] As an optional implementation of the present invention, the protrusion 5 is connected to the top plate by welding.
[0037] The high-pressure resistant heat sink fin 2 reinforcement structure provided by the utility model greatly improves the pressure-bearing capacity of the heat sink fins. When the reinforcement structure is not provided, the pressure-bearing capacity of the heat sink fins does not exceed 4KG. Once it exceeds 4KG, bulging will occur. After the improvement, the pressure-bearing capacity of the heat sink fins is greater than 4kg.
