Abstract

A water-cooling head structure with support fins includes a first shell and a second shell. The first shell has a first plate and at least one fin channel group arranged on the first plate. The second shell has a second plate and is stacked on the first plate to be tightly attached, so that a cavity is formed between the second plate and the first plate, and the fin channel group is located in the cavity. The fin channel group includes a plurality of heat dissipation fins and at least one support fin arranged at intervals. The thickness of the support fin is greater than the thickness of any heat dissipation fin. The support fin has an upper edge, and the inner surface of the second plate is attached to the upper edge of the support fin. By increasing the thickness of the fins in the existing fin design of the water-cooling head, the fins can be used as supports to prevent the water-cooling head from sinking and other problems.

Description

Technical Field

[0001] This utility model relates to a water cooling heat dissipation, and more particularly to a water cooling head structure with supporting fins. Background Technology

[0002] The existing water cooling head is mainly composed of two plates that are closed to form a hollow cavity, and a plurality of fins are provided inside. The working fluid, such as coolant, can pass through the gaps between the fins, thereby carrying away the heat absorbed by the water cooling head, so as to provide cooling and heat dissipation for heat sources such as electronic components.

[0003] Since water cooling blocks often require assembly structures such as fasteners to apply pressure and fit tightly against the heat source surface, the hollow water cooling block is easily dented by external forces, which can damage the flow channels and other structures inside the water cooling block. In particular, it may cause pressure damage to the internal fins, reducing the flow rate of the working fluid at the damaged area and thus affecting the heat exchange efficiency. Utility Model Content

[0043] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0044] Please see Figure 1 and Figure 2 These are exploded perspective views and assembled perspective views of the present invention. The present invention provides a water-cooling head structure with supporting fins, comprising a first housing 1 and a second housing 2; wherein:

[0045] like Figure 3 As shown, the first housing 1 can be made of a material with good thermal conductivity, such as copper or aluminum. The first housing 1 has a first plate portion 10 and at least one fin channel assembly 11 disposed on one surface (such as the inner surface) of the first plate portion 10, while the other surface (such as the outer surface) of the first plate portion 10 is used to attach a heat source (not shown) for heat dissipation or cooling.

[0046] Please see again Figure 1 and Figure 2As shown, the second housing 2 can also be made of a material with good thermal conductivity, such as copper or aluminum. The second housing 2 has a second plate portion 20 that is stacked on top of the first plate portion 10 of the first housing 1 in close contact, so that a cavity C is formed between the second plate portion 20 and the first plate portion 10, and the fin channel assembly 11 on the first plate portion 10 is located within the cavity C. Specifically, in the embodiment of this utility model, the second plate portion 20 of the second housing 2 is recessed on one surface (such as the inner surface) towards the other surface (such as the outer surface), and a protruding top surface 200 is formed on the other surface of the second plate portion 20. A recessed inner surface 201 is formed within the second plate portion 20, and the inner surface 201 abuts against the upper edge of the fin channel assembly 11.

[0047] Furthermore, the second housing 2 may be further provided with a water inlet connector 21 and a water outlet connector 22, and the second plate portion 20 may be provided with a water inlet 20a and a water outlet 20b. Both the water inlet 20a and the water outlet 20b are connected to the aforementioned cavity C. The water inlet connector 21 is connected to the water inlet 20a, and the water outlet connector 22 is connected to the water outlet 20b, so that the water inlet connector 21 can connect to an external pipeline and supply working fluids such as coolant. A recessed section may be provided on the inner surface 201 of the second plate portion 20. The expansion flow channel 201a can be elongated, specifically extending along the arrangement direction of the fin channel group 11. The inlet 20a is located inside the expansion flow channel 201a, allowing the working fluid to enter the cavity C through the inlet 20a and flow and diffuse above the fin channel group 11. This allows it to absorb the heat of the first housing 1 and then be sent out through the outlet 20b to the external pipeline connected to the outlet connector 22, so as to transport the working fluid to components such as water cooling radiators for cooling and recycling.

[0048] Please refer to the following as well. Figure 3 and Figure 4 As shown, the present invention mainly comprises a plurality of heat dissipation fins 110 and at least one support fin 111 arranged at intervals in the aforementioned fin channel assembly 11. The thickness of the support fin 111 is greater than the thickness of any one of the heat dissipation fins 110, and the support fin 111 has an upper edge 111a. The inner surface 201 of the second plate portion 20 abuts against the upper edge 111a of the support fin 111, i.e. Figure 5As shown; furthermore, the upper edge 111a of the support fin 111 can be fixed to the inner surface 201 of the second plate portion 20 by welding or other methods (such as laser welding). Thus, the support fin 111 serves as a support structure between the first housing 1 and the second housing 2 to maintain the space within the cavity C, while preventing damage to the heat dissipation fin 110 caused by external pressure on the first housing 1 or the second housing 2, thereby providing anti-compression and anti-tension effects, and thus helping to maintain the integrity of its internal heat dissipation structure.

[0049] Therefore, through the above-described structural composition, the water-cooling head structure with supporting fins of this utility model can be obtained.

[0050] Accordingly, Figure 5 As shown, the water inlet connector 21 has a water inlet interface 210, and the water outlet connector 22 has a water outlet interface 220. The water inlet connector 21 has an annular water inlet connector seat 211, and the water outlet connector 22 also has an annular water outlet connector seat 221. Meanwhile, in the embodiment of this utility model, the second housing 2 has a first groove 200a recessed on the protruding top surface 200 of the second plate portion 20, corresponding to the water inlet 20a, and a second groove 200b recessed on the inner surface 201, corresponding to the water outlet 20b. The water inlet connector 21 is welded to the first groove 200a with its water inlet connector seat 211, so that the water inlet interface 210 of the water inlet connector 21 is connected to the water inlet 20a. The water outlet connector 22 is welded to the second groove 200b with its water outlet connector seat 221, so that the water outlet interface 220 of the water outlet connector 22 is connected to the water outlet 20b.

[0051] Therefore, the water cooling head structure with supporting fins of this utility model utilizes the existing fin design inside the water cooling head to further increase the thickness of the original fins as needed to become the aforementioned supporting fins 111. The supporting fins 111 can also be increased in multiples depending on the actual area size of the water cooling head design to increase the support strength between the first shell 1 and the second shell 2 to maintain the formation of the cavity C space and help prevent problems such as water cooling head dents.

[0052] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model, or reasonable combinations of features and solutions from various embodiments, are all within the protection scope of the present utility model.
