Description

Technical Field

[0001] This utility model relates to a water cooling head, and more particularly to a water cooling head that can prevent displacement or tilting during the welding of water nozzles. Background Technology

[0002] With air cooling gradually failing to meet the needs of high-power servers, server heat dissipation is increasingly reliant on liquid cooling radiators, and the market share of liquid cooling radiators is growing. As a major and important component of liquid cooling radiators, the liquid cooling head includes water nozzles and a liquid cooling structure, with the water nozzles welded to the liquid cooling structure.

[0003] In existing technologies, the water nozzles of water cooling heads are mostly inserted into the sockets of the liquid cooling structure. The weight of the end of the water nozzle with the nozzle head is relatively greater than the weight of the end of the water nozzle inserted into the socket. Therefore, it is difficult to control the center of gravity of the water nozzle during welding. Since the center of gravity does not fall on the welding joint, the water nozzle will tilt or shift during welding, such as the end of the water nozzle head collapsing, which leads to an increase in the product defect rate.

[0004] Therefore, developing a water cooling head that can consistently prevent the water nozzle from tilting or shifting during welding is one of the problems that researchers should solve. Utility Model Content

[0045] Please see Figures 1 to 4 . Figure 1 This is a three-dimensional schematic diagram of the water cooling head according to the present invention. Figure 2 for Figure 1 A partial decomposition diagram. Figure 3 for Figure 1 A cross-sectional view along the DD direction. Figure 4 for Figure 3 A magnified view of part A in the diagram. (See diagram below.) Figures 1 to 4As shown, the present invention provides a water cooling head 1, comprising: a cold plate structure 11, two water nozzles 12, and at least one limiting member 13; the cold plate structure 11 has an inner cavity C and two insertion holes K1 communicating with the inner cavity; each water nozzle 12 includes a water nozzle head 121 and a tube body 122, one end of the water nozzle head 121 is used to connect to a coolant pipeline, the water nozzle head 121 is installed on the tube body 122 and communicates with the interior of the tube body 122, one end of the tube body 122 is inserted into the insertion hole K1 and communicates with the inner cavity C of the cold plate structure 11; at least one limiting member 13 is disposed on the outer wall of the tube body 11; wherein, when one end of the tube body 122 is inserted into the insertion hole K1, at least one of the limiting members 13 abuts against the hole wall of the insertion hole K1 to limit the tube body 122 from shifting or tilting in the insertion hole K1.

[0046] In this embodiment, it is preferred to integrate the water nozzle 121 and the pipe body 122 as a single unit, but this utility model is not limited thereto.

[0047] In this embodiment, the pagoda-shaped water tap 121 is a preferred implementation, but this utility model is not limited thereto.

[0048] Furthermore, the cold plate structure includes: a first housing 111 and a second housing 112, the top of the first housing 111 is provided with two insertion holes K1, the bottom of the first housing 111 has the inner cavity C; the second housing 112 is installed on the bottom of the first housing 111 and covers the inner cavity C.

[0049] Furthermore, the top of the first housing 111 is provided with two overflow grooves K2, each of which surrounds the insertion hole K1. Since the uncontrolled flow of solder after welding affects the appearance of the water cooling head and may also affect its size, by setting the overflow grooves K2, the flowing solder can be contained during welding, thus ensuring the appearance of the water cooling head while not changing its size.

[0050] In this embodiment, the top of the first housing 1 is provided with a weight reduction hole K3, which is located between the two insertion holes K1. By setting the weight reduction hole K3, the water cooling head 1 is more in line with the thin and light design.

[0051] Furthermore, the pipe body 122 has an open end O, a closed end B, and a pipe body T connecting the open end O and the closed end B. The open end O is inserted into the insertion hole K1 and communicates with the inner cavity C of the cold plate structure 11. The water nozzle 121 is connected to one side of the pipe body T and is located near the closed end B. At least one of the limiting members 13 is disposed on the outer wall of the pipe body T and is located near the open end O. Specifically, at least one of the limiting members 13 is spaced apart along the periphery of the outer wall of the pipe body T.

[0052] In this embodiment, it is preferred to use the limiting member 13 as a protrusion.

[0053] In one embodiment of this utility model, the water tap 12 and the limiting member 13 are an integral part.

[0054] Furthermore, the water block 1 also includes at least one heat dissipation fin 14, which is mounted on the second housing 112. When the second housing 122 is mounted on the first housing 111, at least one of the heat dissipation fins 14 is located in the inner cavity C.

[0055] When this utility model is in use, the heat source is attached to the bottom surface of the second cover 112, so that the heat generated by the heat source can be conducted to the heat dissipation fins 14 through the second cover 112. Then, the heat absorbed by the heat dissipation fins 14 is quickly dissipated by the circulation of coolant between the two water nozzles 12, so as to achieve the purpose of rapid heat dissipation.

[0056] In summary, the water cooling head of this utility model can limit the water nozzle from shifting or tilting in the socket in real time through the limiting component, thereby avoiding the situation of shifting or tilting during the welding of the water nozzle and thus improving the product qualification rate.

[0057] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of protection of the appended claims.
