[0042] Reference Figure 1 、 Figure 3 and Figure 7A control valve 7 is provided above the cabinet body 1, and the inlet end of the control valve 7 is connected to the cabinet body 1. The outlet end of the control valve 7 is fixedly connected to the liquid outlet pipe 10, and the end of the liquid outlet pipe 10 away from the control valve 7 is connected to the input end of the heat exchange elbow 303, and a delivery pump 2 12 is provided below the heat exchange bin 302, and the input end of the delivery pump 2 12 is fixedly connected to a connecting pipe 11, and the end of the connecting pipe 11 away from the delivery pump 2 12 is connected to the output end of the heat exchange elbow 303, and the output end of the delivery pump 2 12 is fixedly connected to a delivery pipe 13, and the end of the delivery pipe 13 away from the delivery pump 2 12 is connected to the annular pipe 203.

[0043] In a specific application scenario, the high-temperature coolant flows slowly from top to bottom in the heat exchange elbow 303, and the suction pump 306 is started to cause the heat exchange medium to circulate. The suction pump 306 pumps the heat exchange medium located above the heat exchange chamber 302 that has completed heat exchange into the bottom of the heat exchange chamber 302 through the heat exchange outlet pipe 309, the heat exchange inlet pipe 305 and the one-way valve 2 304. The heat exchange medium inside the heat exchange chamber 302 flows from bottom to top in the opposite direction of the coolant in the heat exchange elbow 303. The heat exchange medium transfers the heat it carries to the hot end of the thermoelectric generator 308 inside the communication chamber 307. The thermoelectric generator 308 transmits the generated electrical energy to the power supply 311 via the power line 310 to power components such as the temperature detector 4; the thermoelectric generator recovers the waste heat of the high-temperature coolant to generate electricity, which is used to power its own components (such as the temperature detector), reducing external energy consumption. At the same time, the heat exchange elbow and the counter-flowing heat exchange medium can fully exchange heat.

[0044] A heat dissipation method for a liquid-cooled server cabinet, using the heat dissipation device for a liquid-cooled server cabinet as described above, comprises the following steps:

[0045] Step 1: When the temperature detector 4 detects that the internal temperature of the cabinet body 1 is high, the switch valve 14 and the control valve 7 are opened, and the delivery pump 19 is started to pump the low-temperature coolant in the cooling tank 201 into the interior of the cabinet body 1 through the liquid inlet pipe 8 and the one-way valve 6. The high-temperature coolant flows out of the control valve 7 and enters the heat exchange elbow 303 through the liquid outlet pipe 10.

[0046] Step 2: The high-temperature coolant flows slowly from top to bottom in the heat exchange elbow 303, and the suction pump 306 is started to circulate the heat exchange medium. The suction pump 306 pumps the heat exchange medium located above the heat exchange chamber 302 through the heat exchange outlet pipe 309, the heat exchange inlet pipe 305 and the second one-way valve 304 to the bottom of the heat exchange chamber 302 after the heat exchange is completed. The heat exchange medium inside the heat exchange chamber 302 and the coolant in the heat exchange elbow 303 flow from bottom to top in the opposite direction. The heat exchange medium transfers the heat it carries to the hot end of the thermoelectric generator 308 inside the communication chamber 307. The thermoelectric generator 308 transmits the generated electrical energy to the power supply unit 311 via the power line 310, which can power the temperature detector 4 and other components to assist the operation of the device.

[0047] Step 3: Start the delivery pump 2 12, and pump the coolant flowing out of the heat exchange elbow 303 into the annular tube 203 through the connecting pipe 11 and the delivery pipe 13, and then spray it out through the nozzle 205. At the same time, start the drive motor 202 and the cooling fan 212. The drive motor 202 drives the mounting rod 209 and the rotating frame 210 to drive the cooling fan 212 to rotate, so that the cooling fan 212 blows the cool air evenly to the falling coolant. The coolant sprayed from the nozzle 205 and the cool air have a larger heat exchange area, which can improve the cooling efficiency. While the rotating frame 210 rotates, the drive motor 202 drives the mounting rod 209 and the rotating frame 210 to drive the cooling fan 212 to rotate, so that the cooling fan 212 blows the cool air evenly to the falling coolant. The coolant sprayed from the nozzle 205 and the cool air have a larger heat exchange area, which can improve the cooling efficiency. The gear 214 is meshed with the transmission gear ring 204, and the transmission gear 214 and the rotating shaft 213 rotate along with the rotating frame 210 while performing circular motion. The rotating shaft 213 drives the rotating member 215 to rotate, and pulls the rotating rod 206 through the connecting member 216, so that the rotating rod 206 drives the sliding block 217 to slide back and forth continuously. Through the mutual meshing of the rotating gear ring 218 and the rack 219, the rotating rod 206 drives the stirring frame 207 and the cooling rod 208 to rotate while moving back and forth horizontally, thereby evenly cooling the coolant in the cooling tank 201.

The heat dissipation device for a liquid-cooled server cabinet according to claim 8, characterized in that: A control valve (7) is provided above the cabinet body (1), the inlet end of the control valve (7) is connected to the cabinet body (1), the outlet end of the control valve (7) is fixedly connected to a liquid outlet pipe (10), the end of the liquid outlet pipe (10) away from the control valve (7) is connected to the input end of the heat exchange elbow (303), and a delivery pump (12) is provided below the heat exchange chamber (302), the input end of the delivery pump (12) is fixedly connected to a connecting pipe (11), the end of the connecting pipe (11) away from the delivery pump (12) is connected to the output end of the heat exchange elbow (303), the output end of the delivery pump (12) is fixedly connected to a delivery pipe (13), and the end of the delivery pipe (13) away from the delivery pump (12) is connected to the annular pipe (203).

10. A heat dissipation method for a liquid-cooled server cabinet, using the heat dissipation device for a liquid-cooled server cabinet according to claim 9, characterized in that: The steps include: Step 1: When the temperature detector (4) detects that the internal temperature of the cabinet body (1) is high, the switch valve (14) and the control valve (7) are opened, and the delivery pump (9) is started to pump the low-temperature coolant in the cooling tank (201) into the interior of the cabinet body (1), and the high-temperature coolant flows out from the control valve (7) into the heat exchange elbow (303); Step 2: The high-temperature coolant flows slowly from top to bottom in the heat exchange elbow (303), and the suction pump (306) circulates the heat exchange medium. The heat exchange medium inside the heat exchange chamber (302) and the coolant in the heat exchange elbow (303) flow in opposite directions from bottom to top. The heat exchange medium transfers the heat it carries to the hot end of the thermoelectric generator (308), and the thermoelectric generator (308) transmits the generated electrical energy to the power supply (311) to power components such as the temperature detector (4). Step 3: Start the delivery pump 2 (12), pump the coolant flowing out of the heat exchange elbow (303) into the annular tube (203) and spray it out through the nozzle (205), and at the same time start the drive motor (202) and the cooling fan (212), blow the cold air evenly to the falling coolant, and the rotating shaft (213) rotates with the rotating frame (210), forcing the connecting member (216) to pull the rotating rod (206), so that the rotating rod (206) drives the sliding block (217) to slide back and forth continuously, driving the stirring frame (207) and the cooling rod (208) to rotate, and evenly cool the coolant in the cooling tank (201).
