Description

Technical Field

[0001] The utility model relates to the technical field of radiators, and particularly relates to a water-cooled head with multiple cavities, high heat dissipation power and low liquid leakage risk. Background Technique

[0002] Devices such as computers, power supplies, and controllers need to be equipped with corresponding active radiators for heat dissipation. Existing active radiators include: air-cooled radiators, water-cooled radiators, and semiconductor radiators.

[0003] Among them, existing water-cooled radiators include: a water-cooled head and a radiator. The water-cooled head and the radiator are connected through an infusion pipeline, and the radiator is composed of multiple cooling fans and a heat dissipation base. Due to the small space occupied by the water-cooled head of the water-cooled radiator, it is sought after by many users. Therefore, in order to improve the overall heat dissipation efficiency of the water-cooled radiator, some manufacturers have also proposed many improvements. Among them, the improvements to the water-cooled head include: forming multiple heat dissipation chambers in the water-cooled head and forming corresponding refrigerant circulation circuits to improve the heat dissipation effect. Furthermore, heat dissipation fins are arranged in the heat dissipation chambers, so that at least two heat dissipation chambers are equipped with heat dissipation fins, thereby improving the final heat dissipation effect.

[0004] However, there are still some problems with the above improved water-cooled head. For example, forming multiple connected heat dissipation chambers will increase the working pressure of the water pump, and simply connecting the heat dissipation chambers will also cause the flow of some refrigerant to be blocked, resulting in the accumulation of refrigerant at the corners of the chambers, leading to a decrease in the refrigerant circulation efficiency. Furthermore, due to the installation of heat dissipation blocks with heat dissipation fins inside the heat dissipation chambers, the flow pressure of the refrigerant will also increase; the flow path of the refrigerant on the heat dissipation chambers and the heat dissipation fins is relatively direct and simple, resulting in low refrigerant circulation efficiency; and the structural design of multiple heat dissipation chambers and the refrigerant paths formed between them also have a significant impact on the heat dissipation efficiency and the refrigerant circulation efficiency, and cannot be simply and roughly docked.

However, the present utility model can be implemented in many other ways different from this description, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0042] The present utility model discloses a water-cooled head with multiple cavities, high heat dissipation power, and low risk of liquid leakage. Figures 1 - 5 As shown, the water-cooled head is provided with a main body 1. The main body 1 is provided with a pumping chamber 10, a main liquid inlet hole 11, and a main liquid outlet hole 12. The pumping chamber 10 is formed with a liquid inlet hole 101 and a liquid outlet hole 102. The liquid outlet hole 102 is communicated with the main liquid outlet hole 12. The main body 1 is provided with a cooling chamber 13 separated from the pumping chamber 10. The cooling chamber 13 is communicated with the pumping chamber 10 through the liquid inlet hole 101. The cooling chamber 13 is formed with a docking port 130, and the docking port 130 is communicated with the main liquid inlet hole 11.

[0043] As shown in Figure 2 The main liquid outlet hole 12 and the main liquid inlet hole 11 are respectively sealed and connected to a liquid outlet nozzle 15 and a liquid inlet nozzle 14.

[0044] As shown in Figure 2 and Figure 3 The main body 1 is installed with a water pump assembly 2. The upper side of the water pump assembly 2 is covered with an upper cover 4 for protection. The water pump assembly 2 includes a motor 20 and an impeller 21. The impeller 21 of the water pump assembly 2 is arranged in the pumping chamber 10. The water inlet level 210 and the water outlet level 211 of the impeller 21 respectively correspond to the liquid inlet hole 101 and the liquid outlet hole 102.

[0045] As shown in Figure 7 and Figure 8 A cooling plate 5. The cooling plate 5 is provided with a first connection hole 50 and a second connection hole 51. The cooling plate 5 is provided with heat dissipation fins / heat dissipation columns 52. The first connection hole 50 is docked with the liquid inlet hole 101.

[0046] As shown in Figure 9 and Figure 10 and Figure 13 and Figure 14As shown, there is a separator 6. Upper and lower end faces of the separator 6 are respectively provided with an upper cooling chamber 60 and a lower cooling chamber 63. Opposite sides of the upper cooling chamber 60 are provided with channels 601. The channels 601 communicate the upper cooling chamber 60 and the lower cooling chamber 63. The upper cooling chamber 60 is provided with a docking platform 61. The docking platform 61 is located between the two channels 601. The docking platform 61 is provided with a docking hole 610. The docking platform 61 passes through the second connection hole 51 and is connected to the docking port 130. The docking hole 610 communicates with the docking port 130. The docking platform 61 is sealingly connected to the second connection hole 51. The separator 6 is installed in the cooling chamber 13. The cooling plate 5 is installed between the cooling chamber 13 and the upper cooling chamber 60;

[0047] The docking hole 610 communicates the upper cooling chamber 60 and the lower cooling chamber 63. The lower cooling chamber 63 is provided with a guiding groove 64 connected to the docking hole 610. The guiding groove 64 is arranged between the two channels 601. Two ends of the guiding groove 64 extend towards two sides of the lower cooling chamber 63. The extending direction of the guiding groove 64 is different from the orientation of the two channels 601;

[0048] Combined with Figures 11 - 14 As shown, there is a bottom plate 7. An upper end face of the bottom plate 7 is provided with a second heat sink 71. The bottom plate 7 is sealingly connected to the lower cooling chamber 63. The second heat sink 71 is located in the lower cooling chamber 63.

[0049] Specifically, combined with Figure 4 、 Figure 5 As shown, to improve the circulation efficiency of the refrigerant in the water-cooled head, the pumping chamber 10 is arranged on the upper end face of the main body 1, and the cooling chamber 13 is arranged on the lower end face of the main body 1;

[0050] The liquid inlet hole 101 is arranged in the middle range of the pumping chamber 10. The liquid discharge hole 102 is arranged on the side wall of the pumping chamber 10. The docking port 130 is close to one side of the cooling chamber 13 and is located in the middle range between the opposite sides of the cooling chamber 13.

[0051] Specifically, combined with Figure 13 、 Figure 14 As shown, the heat sink / heat dissipation column 52 extends towards the separator 6 (i.e., extends downward), so that when the refrigerant enters the upper cooling chamber 60, it does not need to first cross the cooling plate 5 to contact the heat sink / heat dissipation column 52, thereby reducing the pump load and improving the circulation fluidity, and also improving the heat dissipation efficiency of the separator 6 itself for the refrigerant.

[0052] Furthermore, combined with Figure 9As shown, a step 611 is provided on the periphery of the docking platform 61, the second connection hole 51 is snap-connected to the step 511, and the side of the cooling plate 5 facing away from the heat sink / heat dissipation column 52 abuts against the top surface of the cooling chamber 13.

[0053] Specifically, the heat sink / heat dissipation column 52 guides the refrigerant entering at the channel 601 to the first connection hole 50.

[0054] Combined with Figure 8 , when the heat dissipation column 52 is provided, the heat dissipation column 52 surrounds the first connection hole 50; combined with Figure 7 , Figure 9 , when the heat sink 52 is provided, the heat sink 52 is provided on opposite sides of the first connection hole 50 and forms a flow channel on the other two sides. The orientations of the heat sinks 52 on both sides are the same as the orientations of the channels 601 on both sides. The heat sink 52 faces the first connection hole 50, and the heat sink 52 can be serrated; this achieves improving the smoothness of the refrigerant flowing on the cooling plate 5 and enabling the refrigerant to fully contact the heat sink / heat dissipation column at each position.

[0055] Furthermore, combined with Figure 10 shown, the channel 601 and the guiding groove 64 are in a long strip shape to cooperate to form a refrigerant flow path with higher circulation efficiency and heat dissipation efficiency.

[0056] Specifically, combined with Figure 10 , Figure 13 , Figure 14 shown, the depth of the guiding groove 64 gradually decreases starting from the end where it is connected to the docking hole 610. The cross-section of the guiding groove 64 is in a trapezoidal shape with a narrow top and a wide bottom. The purpose is to guide the refrigerant to flow and prevent the refrigerant from flowing too quickly to the channel 601, enabling the refrigerant to fully contact the second heat sink 71 on the bottom plate 7. The guiding groove 64 and the two channels 601 form a flow path with high smoothness and high circulation efficiency.

[0057] Specifically, combined with Figure 11 shown, a groove 70 is provided on the side of the bottom plate 7 facing the lower cooling chamber 63. The second heat sink 71 extends towards the lower cooling chamber 63 and is provided in the groove 70. The lower cooling chamber 63 is hermetically connected to the groove 70. Furthermore, combined with Figure 9 , Figure 10 shown, a sealing ring 62 is connected to the periphery of the partition member 6. The sealing ring 62 is used to seal the connection gap between the main body 1, the partition member 6, and the bottom plate 7.

[0058] Combined with Figure 13 , Figure 14As shown, the refrigerant circulation path is as follows: The refrigerant enters from the main liquid inlet hole 11 and flows through the docking port 130 and the docking hole 610 in sequence to enter the guiding groove 64, and then the refrigerant enters a part of the second heat sink 71 corresponding to the lower side of the guiding groove 64. The refrigerant flows towards the upper and lower ends of the lower cooling chamber 63 under the guidance of the guiding groove 64 and diffuses towards the left and right ends until it covers the second heat sink 71 of the bottom plate 7.

[0059] Under the suction of the water pump assembly 2, the refrigerant in the lower cooling chamber 63 flows towards the left and right ends and enters the upper cooling chamber 60 through the channels 601 on both sides, and then the refrigerant flows towards the direction of the first connection hole 50 located in the middle position. During the flowing process, the refrigerant passes through the heat sink / heat dissipation column 52 on the cooling plate 5 from outside to inside in sequence. During this period, the flowing of the refrigerant converges towards the middle and upper parts; finally, the refrigerant enters the pumping chamber 10 through the liquid inlet hole 101, and the water pump assembly 2 discharges the refrigerant from the liquid discharge hole 102 and the main liquid discharge hole 12 to the outside in sequence. This refrigerant circulation path can improve the circulation efficiency and circulation smoothness of the refrigerant, and ultimately improve the heat dissipation efficiency of the water-cooled head.

[0060] Specifically, in combination with Figure 6 As shown, it further includes: a clamping assembly 3, and the clamping assembly 3 is used for the firm installation of the water-cooled head on the heat source. The clamping assembly 3 includes: a pressing plate 30 and a fastening assembly 32. The pressing plate 30 is provided with a fastening groove 31 matching the main body 1, and a limiting step 310 is arranged on the edge of the fastening groove 31, and the edge of the main body 1 is clamped with the limiting step 310;

[0061] The fastening assembly 32 connects the pressing plate 30 and the heat source. The fastening assembly 32 includes: a bolt 320, a spring 321 and a gasket 322. The spring 321 is sleeved on the bolt 320. The second end of the bolt 320 is connected with the gasket 322 and is arranged on the lower side of the pressing plate 30. The first end of the spring 321 abuts against the first end of the bolt 320, and the second end of the spring 321 abuts against the upper side of the pressing plate 30.

[0062] To sum up, a cooling plate and a bottom plate with heat sinks are arranged in the upper and lower cooling chambers to improve the heat dissipation efficiency inside the water-cooled head. Among them, a new refrigerant circulation path is formed through the pumping chamber, the cooling chamber, the upper cooling chamber, the lower cooling chamber, the cooling plate and the partition and the structures inside them to improve the circulation efficiency and circulation smoothness of the refrigerant, avoid that some refrigerant is difficult to circulate or rotate in local positions, improve the contact between the refrigerant and the heat sinks of the cooling plate and the bottom plate, and ultimately improve the heat dissipation efficiency; the structure ensures the sealing performance of the water-cooled head and avoids liquid leakage and the over-large volume of the water-cooled head.
