[0028] Example 1:

[0029] Please see Figures 1 to 4This application provides a liquid cooling heat dissipation device, which includes at least one liquid cooling plate unit 10 and a main body plate 20; each liquid cooling plate unit 10 includes a receiving cavity 11 and a first connector 12, the first connector 12 being housed in the receiving cavity 11, the main body plate 20 being mounted on the liquid cooling plate unit 10, and at least one second connector 21 and at least one leakage recovery cavity 22 on the main body plate 20; each first connector 12 is connected to a corresponding second connector 21, each receiving cavity 11 and the corresponding leakage recovery cavity 22 are closedly connected to form a leakage recovery channel (not shown in the figure), and the connection point between each second connector 21 and the corresponding first connector 12 is located in the corresponding leakage recovery channel.

[0030] Understandably, in one embodiment, the first connector 12 can be an inlet connector for supplying coolant to the liquid-cooled plate unit 10; the second connector 21 is correspondingly connected to the first connector 12 and is used to supply coolant to the liquid-cooled plate unit 10. In another embodiment, the first connector 12 can also be an outlet connector for discharging the coolant that has undergone heat exchange in the liquid-cooled plate unit 10; the second connector 21 is correspondingly connected to the first connector 12 and is used to discharge the liquid in the liquid-cooled plate unit 10. In both embodiments above, whether the first connector 12 is used as an inlet connector or an outlet connector, it is housed within the receiving cavity 11, and the receiving cavity 11 is closed and connected to the corresponding leakage recovery cavity 22 to form a leakage recovery channel. The connection between the second connector 21 and the first connector 12 is also located within the corresponding leakage recovery channel. Therefore, the coolant leaked at the connection between the first connector 12 and the liquid-cooled plate unit 10, and at the connection between the first connector 12 and the second connector 21, can be recovered and collected through the leakage recovery channel, avoiding the leakage of coolant from affecting other components and ensuring the heat dissipation effect of the liquid cooling device.

[0031] In one specific embodiment of this application, please refer to Figures 1 to 4Each first connector 12 includes a first liquid inlet connector 121 and a first liquid outlet connector 122; each second connector 21 includes a second liquid inlet connector 211 and a second liquid outlet connector 212. The first liquid inlet connector 121 of each first connector 12 is connected to the second liquid inlet connector 211 of the corresponding second connector 21; the first liquid outlet connector 122 of each first connector 12 is connected to the second liquid outlet connector 212 of the corresponding second connector 21. Coolant flows sequentially from the second liquid inlet connector 211 and the first liquid inlet connector 121 into the corresponding liquid-cooled plate unit 10. The coolant flows within the liquid-cooled plate unit 10 according to a preset path and exchanges heat with the surrounding environment of the liquid-cooled plate unit 10. Then, it flows sequentially through the first liquid outlet connector 122 and the second liquid outlet connector 212 out of the liquid-cooled plate unit 10 and flows into other cooling devices to cool the coolant that has undergone heat exchange, so that it can be recycled next time. In this embodiment, the connection between each first liquid inlet connector 121 and the corresponding second liquid inlet connector 211, and the connection between each first liquid outlet connector 122 and the corresponding second liquid outlet connector 212, are all located in the leakage recovery channel. This ensures that the coolant leaked from the connection between each second connector 21 and the corresponding first connector 12 flows into the leakage recovery channel, preventing the leaked coolant from affecting other components and ensuring the heat dissipation effect of the liquid cooling device.

[0032] Furthermore, the first connector 12 and the second connector 21 are pluggable connections, which facilitates the installation and removal of the first connector 12 and the second connector 21.

[0033] Please see Figures 1 to 4 The main plate 20 also includes a drain channel 23, which is used to drain the cold liquid inside the liquid cooling plate unit 10; wherein, the first liquid inlet connector 121 is connected to the second liquid inlet connector 211; the first liquid outlet connector 122 is connected to the second liquid outlet connector 212; the liquid supply channel 25 is connected to the second liquid inlet connector 211, and the drain channel 23 is connected to the second liquid outlet connector 212.

[0034] By connecting the liquid supply channel 25 to the second liquid inlet connector 211, and then connecting the first liquid inlet connector 121 to the second liquid inlet connector 211, the coolant inside the liquid supply channel 25 is input into each liquid cooling plate unit 10. By connecting the first liquid outlet connector 122 to the second liquid outlet connector 212, the coolant output from each liquid cooling plate unit 10 is received. Then, by connecting the drain channel 23 to the second liquid outlet connector 212, the coolant output from the second liquid outlet connector 212 is received, and flow management is performed. By connecting the liquid supply channel 25 to the second liquid inlet connector 211, the first liquid inlet connector 121 to the second liquid inlet connector 211, the first liquid outlet connector 122 to the second liquid outlet connector 212, and the drain channel 23 to the second liquid outlet connector 212, the coolant in the liquid cooling plate unit 10 is circulated, which facilitates the heat dissipation of the liquid cooling plate unit 10.

[0035] Please see Figures 1 to 4 Each leakage recovery chamber 22 includes a first leakage recovery chamber 221 communicating with the receiving chamber 11 and a second leakage recovery chamber 222 communicating with the first leakage recovery chamber 221. The first leakage recovery chamber 221 is connected to the receiving chamber 11 along the direction of gravity; after the second leakage recovery chamber 222 is connected to the first leakage recovery chamber 22, the second leakage recovery chamber 222 extends along the direction of gravity.

[0036] By utilizing the fact that the first leakage recovery chamber 221 is connected to the receiving chamber 11 along the direction of gravity, all the coolant leaking in the receiving chamber 11 can flow into the first leakage recovery chamber 221. Then, by utilizing the fact that the second leakage recovery chamber 222 is connected to the first leakage recovery chamber 221 and extends along the direction of gravity, all the coolant leaking in the first leakage recovery chamber 221 can flow out through the second leakage recovery chamber 222.

[0037] In one embodiment, each liquid-cooled plate unit 10 is provided with a mounting protrusion 13, and a receiving cavity 11 is disposed on the mounting protrusion 13; the main body plate 20 includes a mounting plane (not shown in the figure), a second connector 21 is disposed on the mounting plane, and a leakage recovery cavity 22 penetrates through the mounting plane; the mounting plane is fixed to the liquid-cooled plate unit 10 and covers the receiving cavity 11.

[0038] Please see Figure 2 In another embodiment, the main body plate 20 is provided with a mounting part 24, the mounting part 24 is provided with a mounting groove 241, the second connector 21 is disposed in the mounting groove 241, the leakage recovery chamber 22 communicates with the mounting groove 241, and the mounting groove 241 is fixedly connected to and communicates with the receiving cavity 11. Specifically, the mounting groove 241 is fitted onto the mounting protrusion 13, and the mounting groove 241 communicates with the receiving cavity 11. Each liquid cooling plate unit 10 is provided with a mounting protrusion 13, the receiving cavity 11 is disposed on the mounting protrusion 13, and the mounting groove 241 is fitted onto the mounting protrusion 13.

[0039] Specifically, the main body plate 20 is installed and fixed to each liquid-cooled plate unit 10, and the leakage recovery chamber 22 is connected to the receiving chamber 11. The mounting groove 241 is fitted onto the mounting protrusion 13, so that the mounting protrusion 13 is fitted onto the mounting part 24, thus the main body plate 20 is installed and fixed to each liquid-cooled plate unit 10, and the leakage recovery chamber 22 is connected to the receiving chamber 11. The mounting protrusion 13 is fitted onto the mounting part 24 to ensure that the coolant in the receiving chamber 11 can flow completely into the mounting groove 241, thereby improving the installation and fixation of the main body plate 20 and each liquid-cooled plate unit 10 and reducing the probability of coolant leakage from the connection between the mounting groove 241 and the mounting protrusion 13.

[0040] Please see Figure 2 The liquid cooling heat dissipation device further includes a first sealing element 30, which is disposed between the mounting protrusion 13 and the mounting groove 241.

[0041] Specifically, the first seal 30 is used to reduce the probability of coolant leakage at the connection between the mounting protrusion 13 and the mounting groove 241.

[0042] Please see Figure 2 The liquid cooling heat dissipation device also includes a second sealing element 40, which is located at the connection between the first connector 12 and the liquid cooling plate unit 10, reducing the probability of liquid leakage at the connection between the liquid cooling plate unit 10 and the first connector 12.

[0043] Please see Figure 2 The liquid cooling heat dissipation device also includes a third sealing element 50, which is located at the connection between the second connector 21 and the main body plate 20, reducing the probability of liquid leakage at the connection between the main body plate 20 and the second connector 21.

[0044] Please see Figure 1 , Figure 2 and Figure 4 The liquid cooling heat dissipation device further includes at least one liquid detector 60 and a processor (not shown in the figure) connected to the liquid detector 60; each liquid detector 60 is installed in a corresponding leakage recovery channel; the processor displays the results or alarms based on the detection results detected by the liquid detector 60.

[0045] Specifically, the liquid detector 60 is used to detect leakage inside the leakage recovery channel, and the processor is used to display faults or issue alarms, so that users can repair or replace the liquid cooling device in a timely manner.

[0046] Please see Figure 1 , Figure 2 and Figure 4The liquid cooling heat dissipation device further includes at least one liquid detector 60 and a processor connected to the liquid detector 60; each liquid detector 60 is installed in a corresponding leakage recovery channel; the main body plate 20 also includes a liquid supply channel 25, which is used to supply coolant to the liquid cooling plate unit 10; the liquid supply channel 25 is provided with a control valve 70, which is connected to the processor; the processor displays or alarms the results based on the detection results detected by the liquid detector 60; and the processor controls the control valve 70 based on the detection results detected by the liquid detector 60.

[0047] Specifically, the liquid detector 60 detects leakage inside the leakage recovery channel, and the processor displays or alarms the fault. Then, the control valve 70 controls the flow of the liquid supply channel 25 to prevent the leakage of the faulty liquid cooling plate unit 10 from worsening, making it convenient for users to repair or replace the liquid cooling heat dissipation device. When the leakage detected by the liquid detector 60 reaches a specified threshold, the processor sends a control signal to the control valve 70 to select whether to close it, so that the flow of coolant transmitted from the liquid supply channel 25 to the second connector 21 is reduced, or to close it completely, so that the liquid supply channel 25 completely stops transmitting coolant to the second connector 21. After the repair or replacement is completed, the control valve 70 reopens, so that the liquid supply channel 25 transmits coolant to the second connector 21.

[0048] Please see Figure 1 and Figure 3 The liquid cooling heat dissipation device also includes multiple liquid cooling plate units 10 arranged side by side. The main plate 20 also includes a liquid inlet channel 26. The number of liquid detectors 60, the number of liquid supply channels 25, and the number of liquid discharge channels 23 are the same as the number of liquid cooling plate units 10, and each liquid supply channel 25 is connected to the liquid inlet channel 26. The main plate 20 also includes a liquid outlet channel 27, and each liquid discharge channel 23 is connected to the liquid outlet channel 27. The main plate 20 also includes a leakage channel 28, and each leakage recovery chamber 22 is connected to the leakage channel 28. The leakage channel 28 is also provided with a leakage outlet (not shown in the figure), which is used to discharge liquid.

[0049] Multiple liquid-cooled plate units 10 arranged side by side are used to achieve multi-channel liquid cooling. Each liquid supply channel 25 is connected to the liquid inlet channel 26, so that the coolant inside the liquid inlet channel 26 is distributed to multiple liquid supply channels 25 to realize the input of coolant to the liquid-cooled plate unit 10. Each liquid discharge channel 23 is connected to the liquid outlet channel 27, so that the coolant inside the multiple liquid-cooled plate units 10 flows through the liquid discharge channel 23 to the liquid outlet channel 27 to realize the collection of coolant after use. Each leakage recovery chamber 22 is connected to the leakage channel 28, so that the coolant leaking from the multiple liquid-cooled plate units 10 flows through the leakage recovery chamber 22 to the leakage channel 28, and then the leaked coolant is discharged through the leakage outlet.

[0050] Please see Figure 1 and Figure 4 The output port of the liquid inlet channel 26 is connected to the liquid supply channel 25, and the input port of the liquid inlet channel 26 is equipped with an input valve 80 to control the liquid inlet status of the liquid inlet channel 26.

This facilitates individual maintenance of faulty liquid cooling plate units 10 and ensures the normal operation of other liquid cooling plate units 10. Furthermore, the control valve 70 is an electromagnetic fluid valve.

[0054] The working principle of the liquid cooling heat dissipation device of this application is as follows: Two sets of first connectors 12 and second connectors 21 are provided. The first connector 12 of the first set, combined with its corresponding second connector 21 of the first set, inputs coolant to each liquid cooling plate unit 10. The first connector 12 of the second set, combined with its corresponding second connector 21 of the second set, receives the coolant output from each liquid cooling plate unit 10. The first connector 12 is housed within a receiving cavity 11, allowing coolant leaking from the connection point of the first connector 12 on the liquid cooling plate unit 10 to first flow into the receiving cavity 11. Then, each receiving cavity 11 and... The corresponding leakage recovery chamber 22 is closed and connected to form a leakage recovery channel, so that the coolant leaking from the connection of the first connector 12 on the liquid cooling plate unit 10 flows into the leakage recovery channel; by using the connection of each second connector 21 to the corresponding first connector 12 located in the corresponding leakage recovery channel, the coolant leaking from the connection of each second connector 21 to the corresponding first connector 12 flows into the leakage recovery channel, avoiding the leakage coolant from affecting other components, ensuring the heat dissipation effect of the liquid cooling heat dissipation device, and the leaked coolant can be recovered and discharged by separately processing the leakage recovery channel.
