[0038] The refrigerant circulation system 10 includes an evaporator 11, a compressor 14, a condenser 13, and a throttling element 12 connected in sequence to form a refrigerant circulation system. Optionally, the throttling element 12 is a throttling valve.

[0039] The liquid cooling circulation system 20 includes a liquid cooling component 21. The heat exchange medium in the liquid cooling circulation system 20 exchanges heat with the refrigerant in the evaporator 11, so that the refrigerant in the evaporator 11 cools the heat exchange medium in the liquid cooling circulation system 20, thereby lowering the temperature of the heat exchange medium in the liquid cooling circulation system 20. The liquid cooling component 21 is used to cool the target area.

[0040] Specifically, the liquid cooling circulation system 20 includes a heat exchange section, the first end of which is connected to the liquid outlet of the liquid cooling component 21, and the second end of which is connected to the liquid inlet of the liquid cooling component 21; the heat exchange medium in the heat exchange section is used to exchange heat with the refrigerant in the evaporator 11.

[0041] Specifically, the heat exchange medium in the liquid cooling circulation system 20 is a liquid.

[0042] In this application, the liquid cooling unit further includes a liquid storage component 30 and a cooling component 33; the liquid cooling circulation system 20 is provided with a first connection point 201 and a second connection point 202, the first connection point 201 is located upstream of the liquid cooling component 21, and the second connection point 202 is located downstream of the liquid cooling component 21; the outlet of the liquid storage component 30 is connected to the first connection point 201 through a first pipe 31, and the inlet of the liquid storage component 30 is connected to the second connection point 202 through a second pipe 32; both the first pipe 31 and the second pipe 32 can be switched on and off; the cooling component 33 is used to cool the liquid in the liquid storage component 30.

[0043] In practice, the liquid-cooled unit has a first operating mode and a second operating mode.

[0044] When the liquid chiller is in the first operating mode, both the first pipe 31 and the second pipe 32 are disconnected; the refrigerant circulation system 10 starts to operate, and the refrigerant in the evaporator 11 is used to cool the heat exchange medium in the liquid cooling circulation system 20.

[0045] When the liquid chiller is in the second operating mode, the refrigerant circulation system 10 is not started; the first pipe 31 and the second pipe 32 are both connected. The cooling component 33 cools the liquid in the liquid storage component 30. The liquid with a lower temperature in the liquid storage component 30 flows through the first pipe 31 into the pipe between the first connection point 201 of the liquid cooling circulation system 20 and the liquid cooling component 21, and then flows into the liquid cooling component 21, thereby making the temperature of the heat exchange liquid in the liquid cooling component 21 lower. The liquid flowing out of the liquid cooling component 21 flows through the pipe between the liquid cooling component 21 and the second connection point 202 of the liquid cooling circulation system 20, and then flows back into the liquid storage component 30, thus forming a refrigeration cycle.

[0046] Specifically, a first control valve 311 is provided on the first pipeline 31 to control the opening and closing of the first pipeline 31 and regulate the liquid flow rate in the first pipeline 31.

[0047] Specifically, a second control valve 321 is provided on the second pipeline 32 to control the opening and closing of the second pipeline 32 and regulate the liquid flow rate in the second pipeline 32.

[0048] Optionally, the first control valve 311 is a solenoid valve; the second control valve 321 is a solenoid valve.

[0049] Optionally, the liquid storage component 30 is a liquid storage tank.

Both the third pipe 35 and the fourth pipe 36 can be switched on and off. The heat exchanger 34 is located on one side of the condenser 13.

[0051] When the liquid-cooled unit is in the first operating mode, the condenser 13 releases heat, and the temperature of the condenser 13 is relatively high. Therefore, the heat exchanger 34 is surrounded by hot air formed by the heat released by the condenser 13. The third pipe 35 and the fourth pipe 36 are both connected. The cooling component 33 cools down the liquid in the liquid storage component 30. The lower-temperature liquid in the liquid storage component 30 enters the heat exchanger 34 through the third pipe 35. The lower-temperature liquid in the heat exchanger 34 exchanges heat with the surrounding hot air to cool down the surrounding hot air. The cooled air then exchanges heat with the condenser 13 to cool down the condenser 13. The liquid flowing out of the heat exchanger 34 flows back to the liquid storage component 30 through the fourth pipe 36.

[0052] Specifically, a third control valve 361 is provided on the fourth pipeline 36 to control the opening and closing of the fourth pipeline 36 and regulate the liquid flow rate in the fourth pipeline 36.

[0055] Specifically, a filter 371 is installed on the fifth pipeline 37 to filter the liquid flowing out from the outlet of the liquid storage component 30.

[0056] Optionally, filter 371 is a Y-type filter.

[0057] Specifically, a liquid supply pump 372 is provided on the fifth pipeline 37 to pump the liquid in the liquid storage component 30 into the first pipeline 31 and / or the third pipeline 35 under the action of the liquid supply pump 372.

[0058] Specifically, the second end of the fifth pipeline 37 is connected to the first end of the third pipeline 35 and the first end of the first pipeline 31 via a three-way valve 373; the three-way valve 373 is used to connect the fifth pipeline 37 with the third pipeline 35 and / or the first pipeline 31.

[0059] When the liquid chiller is in the first operating mode, the fifth pipe 37 is only connected to the third pipe 35.

[0060] In this application, the liquid cooling unit also includes a sixth pipe 38; the first end of the second pipe 32 is connected to the second connection point 202, the first end of the fourth pipe 36 is connected to the liquid outlet of the heat exchanger 34; the second ends of the second pipe 32 and the second ends of the fourth pipe 36 are both connected to the first end of the sixth pipe 38, and the second end of the sixth pipe 38 is connected to the liquid inlet of the liquid storage component 30.

[0061] In this application, a third connection point 362 is provided on the fourth pipeline 36; a fourth connection point 204 is provided on the liquid cooling circulation system 20. The fourth connection point 204 is located downstream of the first connection point 201 and upstream of the liquid cooling component 21.

[0062] The liquid cooling unit also includes a seventh pipe 39, the two ends of which are connected to the third connection point 362 and the fourth connection point 204 respectively; the seventh pipe 39 is configured to be switchable; the pipe section between the third connection point 362 of the fourth pipe 36 and the liquid inlet of the liquid storage component 30 is configured to be switchable.

[0063] The third connection point 362 divides the fourth pipeline 36 into a first pipe segment 363 and a second pipe segment 364, that is, the fourth pipeline 36 includes a first pipe segment 363 and a second pipe segment 364; the first pipe segment 363 is the pipe segment between the liquid outlet of the heat exchanger 34 and the third connection point 362; the second pipe segment 364 is the pipe segment between the third connection point 362 and the liquid inlet of the liquid storage component 30, that is, the second pipe segment 364 is the pipe segment between the third connection point 362 and the first end of the sixth pipeline 38; the second pipe segment 364 can be switched on and off.

[0064] When the liquid cooler is in the first operating mode, the seventh pipe 39 is disconnected and the second pipe section 364 is connected. At this time, the liquid in the heat exchanger 34 flows back to the liquid storage component 30 through the first pipe section 363 and the second pipe section 364.

[0065] When the liquid cooler unit is in the second operating mode, the seventh pipe 39 is in the connected state, and the second pipe section 364 is in the disconnected state. The liquid flowing out of the liquid storage component 30 flows into the fifth pipe 37, and the liquid flowing out of the fifth pipe 37 is divided into two branches. The liquid in the first branch flows into the first pipe 31, and then into the pipe between the first connection point 201 of the liquid cooling circulation system 20 and the liquid cooling component 21. The liquid in the second branch flows through the third pipe 35, the heat exchanger 34, the first pipe section 363, and the seventh pipe 39 in sequence before flowing into the upstream pipe section of the liquid cooling component 21. That is, the liquid with a lower temperature in the liquid storage component 30 flows into the upstream pipe section of the liquid cooling component 21 through the two branches, and then flows into the liquid cooling component 21.

[0066] Specifically, a fourth control valve 391 is provided on the seventh pipeline 39 to control the opening and closing of the seventh pipeline 39 and regulate the liquid flow rate in the seventh pipeline 39.

[0067] Optionally, the fourth control valve 391 is a solenoid valve.

[0069] In this application, the liquid cooling unit also includes a first air blowing component 131, the air outlet of the first air blowing component 131 is arranged toward the heat exchange component 34, so that the first air blowing component 131 blows air onto the heat exchange component 34, thereby reducing the liquid temperature inside the heat exchange component 34.

[0070] When the liquid cooling unit is in the second operating mode, the first blowing component 131 blows air onto the heat exchange component 34 to further reduce the liquid temperature inside the heat exchange component 34; this helps to make the liquid temperature flowing into the liquid cooling component 21 even lower.

[0071] Specifically, the air outlet of the first blowing component 131 is positioned toward the heat exchanger 34 or the condenser 13.

[0072] When the liquid cooling unit is in the first operating mode, the air outlet of the first air blowing component 131 is set towards the condenser 13 so that the first air blowing component 131 blows air onto the condenser 13, thereby cooling and dissipating heat from the condenser 13.

[0074] Optionally, the first blowing component 131 is a blower or fan.

[0075] Optionally, the first air blowing component 131 is located between the heat exchanger 34 and the condenser 13; when the liquid cooling unit is in the first operating mode, the first air blowing component 131 can blow the cold air from the heat exchanger 34 side to the condenser 13 to better cool and dissipate heat from the condenser 13.

[0076] In this application, the pipeline between the first end of the heat exchange section and the liquid outlet of the liquid cooling component 21 is the eighth pipeline 22; the pipeline between the second end of the heat exchange section and the liquid inlet of the liquid cooling component 21 is the ninth pipeline 23.

[0077] Specifically, the first connection point 201 and the second connection point 202 are both located on the eighth pipe 22, and the fourth connection point 204 is located on the ninth pipe 23.

[0078] Specifically, a first pump body 221 is installed on the eighth pipeline 22 so that the liquid in the liquid cooling circulation system 20 enters the heat exchange section under the action of the first pump body 221.

[0079] Specifically, the first pump body 221 is located between the first connection point 201 and the heat exchange section.

[0084] Optionally, the water pressure detection element 223 is located between the liquid cooling component 21 and the second connection point 202. Optionally, the water pressure detection element 223 is a water pressure sensor.

[0085] In this application, when the pressure of the liquid cooling circulation system 20 is adjusted to the preset water pressure, and when the liquid cooling unit is about to exit the second operating mode, the liquid supply pump 372 will not immediately stop at zero speed. Therefore, at this time, the liquid pumped by the liquid supply pump 372 flows back to the liquid storage component 30 through the third pipeline 35, heat exchanger 34, fourth pipeline 36, and sixth pipeline 38 to avoid interfering with the stable water pressure of the liquid cooling circulation system 20.

[0086] Optionally, the liquid supply pump 372 is a variable speed pump, so as to regulate the water pressure of the liquid cooling circulation system 20 by adjusting the frequency of the liquid supply pump 372.

[0087] In this application, a sixth connection point 351 is provided on the third pipeline 35; the liquid cooling unit also includes a tenth pipeline 40, the first end of the tenth pipeline 40 is connected to the liquid outlet of the liquid storage component 30, and the second end of the tenth pipeline 40 is connected to the sixth connection point 351; an auxiliary pump 401 is provided on the tenth pipeline 40, and the auxiliary pump 401 is used to provide auxiliary power for supplying liquid to the heat exchange component 34.

[0088] In the specific implementation process, when the liquid cooling unit is operating in the second operating mode, the liquid flowing out from the fifth pipe 37 is divided into two branches. When the flow rate of the second branch is small, the auxiliary pump 401 can be turned on to supply liquid to the second branch through the tenth pipe 40 under the action of the auxiliary pump 401, so as to increase the flow rate of the second branch.

[0089] When the liquid chiller is operating in the first operating mode, although the liquid flowing out of the fifth pipe 37 only flows to the heat exchanger 34, the auxiliary pump 401 can be turned on at this time. Under the action of the auxiliary pump 401, liquid is supplied to the heat exchanger 34 through the tenth pipe 40 to increase the liquid flow rate in the heat exchanger 34.

[0090] Optionally, when the liquid cooling unit is operating in the first operating mode and the temperature of the condenser 13 is high, the auxiliary pump 401 can be turned on to increase the cooling effect on the condenser 13.

[0091] Specifically, a fifth connection point 374 is provided on the fifth pipe 37, which divides the fifth pipe 37 into a third pipe segment and a fourth pipe segment; the end of the third pipe segment away from the fourth pipe segment is the first end of the fifth pipe 37, and the end of the fourth pipe segment away from the third pipe segment is the second end of the fifth pipe 37.

[0092] Specifically, the first end of the tenth pipeline 40 is connected to the fifth connection point 374 so that the tenth pipeline 40 is connected to the outlet of the liquid storage component 30 through the third pipeline section; the liquid supply pump 372 is installed on the fourth pipeline section.

[0096] Optionally, the level detection element 50 is a level gauge.

[0098] Specifically, when the liquid level in the liquid storage component 30 is lower than the preset liquid level, liquid is automatically replenished into the liquid storage component 30 through the replenishment pipe 60.

[0099] Optionally, the first end of the replenishment pipe 60 is used to connect to a water source. For example, the first end of the replenishment pipe 60 is used to connect to a tap water source in a computer room or industrial area.

[0100] In this application, the liquid storage component 30 includes a first liquid storage section 301 and a second liquid storage section 302, with the first liquid storage section 301 located above the second liquid storage section 302.

A cooling component 33 is located on one side of the flow-diverting assembly 70 to cool the liquid flowing through it.

[0104] In this application, the diversion assembly 70 includes multiple diversion channels. Liquid in the first liquid storage section 301 enters each diversion channel through the upper end of each diversion channel, and liquid in each diversion channel flows into the second liquid storage section 302 through its lower end.

The cooling component 33 is a second air blowing component, and the air outlet of the second air blowing component is arranged facing the diversion assembly 70 to blow air onto the diversion assembly 70, thereby causing the air blown out by the diversion assembly 70 to be blown onto the liquid in the diversion channel through the vent holes to cool the liquid in the diversion channel.

[0105] Optionally, the second blowing component is a blower or fan.

[0106] Specifically, the diversion assembly 70 includes multiple diversion pipes 71, and the lumen of each diversion pipe 71 forms a diversion channel, that is, a vent hole is provided on the pipe wall of the diversion pipe 71.

When multiple vent holes are provided on the channel wall of the branch channel, at least a portion of the multiple vent holes are distributed along the axial direction of the branch channel, and / or at least a portion of the multiple vent holes are distributed along the circumferential direction of the branch channel.

[0108] In this application, the flow-diverting assembly 70 also includes a flow-diverting mesh 72, which is disposed within the flow-diverting channel so that the liquid in the flow-diverting channel is diverted by the flow-diverting mesh 72 when it flows through the flow-diverting mesh 72; that is, the liquid is diverted into a dripping form when it flows through the flow-diverting mesh 72.

[0114] In this application, the first liquid storage section 301 is provided with a plurality of flow channels 3011, the upper end of each flow channel 3011 is connected to the liquid inlet of the liquid storage component 30, and the liquid flowing out from the lower end of each flow channel 3011 flows through the diversion component 70; the liquid entering through the liquid inlet of the liquid storage component 30 is initially diverted through the plurality of flow channels 3011.

[0115] Optionally, the diameter or equivalent diameter of the flow channel 3011 is smaller to form a narrow channel.

[0116] Optionally, the flow channel 3011 extends vertically.

[0117] Optionally, in this application, the liquid inlet of the liquid storage component 30 is located at its top or upper part, that is, the liquid inlet of the liquid storage component 30 is located at the top or upper part of the first liquid storage section 301. For example, Figure 3 The liquid inlet 303 is the liquid inlet of the liquid storage component 30.

[0118] Optionally, in this application, the outlet of the liquid storage component 30 is located at its bottom or lower part, that is, the outlet of the liquid storage component 30 is located at the bottom or lower part of the second liquid storage section 302. For example, Figure 3 The liquid outlet 304 is the liquid outlet of the liquid storage component 30.

[0119] In this application, the liquid storage component 30 has a replenishment port that communicates with the internal cavity of the liquid storage component 30, and the second end of the replenishment tube 60 is connected to the replenishment port so that the second end of the replenishment tube 60 communicates with the internal cavity of the liquid storage component 30 through the replenishment port.

[0120] Specifically, the liquid replenishment port of the liquid storage component 30 is located on the first liquid storage section 301.

[0121] Optionally, the replenishment port of the liquid storage component 30 is located at its top or upper part, that is, the replenishment port of the liquid storage component 30 is located at the top or upper part of the first liquid storage part 301.

[0122] In this application, the first liquid storage section 301 and the second liquid storage section 302 are connected by a connector, but the connector does not block the vent of the diversion channel of the diversion assembly 70, nor does it block the air blown out by the second blowing component.

[0123] In this application, a dustproof net 73 is provided on the outer side of the diversion component 70.

[0124] Optionally, the dustproof net 73 is connected and fixed to the first liquid storage section 301 and / or the second liquid storage section 302.

[0125] In this application, during the specific implementation process, in the refrigerant circulation system 10, the refrigerant is compressed by the compressor 14, condensed by the condenser 13, throttled by the throttling device 12, and then evaporates and absorbs heat through the evaporator 11. This is the conventional refrigeration cycle process. In this conventional refrigeration cycle process, the first blower component 131 is simultaneously turned on, and the air outlet of the first blower component 131 is set towards the condenser 13 to dissipate heat and cool the condenser 13 through the first blower component 131. The first pump body 221 is simultaneously turned on, and the first control valve 311, the second control valve 321, the third control valve 361, and the fourth control valve 391 are all in the closed state. The liquid in the liquid cooling circulation system 20 is powered by the first pump body 221 to exchange heat with the refrigerant in the heat exchange section, that is, the liquid in the heat exchange section releases heat and cools down. The cooled liquid flows into the liquid cooling component 21 to cool the target area; that is, the unit operates in the first operating mode at this time.

[0126] When the ambient temperature is high, the condenser 13 has difficulty dissipating heat, resulting in increased condensation temperature, power consumption, and current. This can easily lead to high pressure, exhaust, or current protection issues in the unit. In the liquid-cooled unit of this application, when the ambient temperature is high, the auxiliary pump 401 and / or the liquid supply pump 372 are started, the third control valve 361 opens simultaneously, the cooling component 33 is activated, and the liquid in the liquid storage component 30 begins to circulate. The liquid flows from the inlet of the liquid storage component 30 into the first liquid storage section 301, then flows through the diversion assembly 70, and is evaporated by the second air blowing component. The liquid is cooled to near the wet-bulb temperature, and the low-temperature liquid flows out from the outlet of the liquid storage component 30, sequentially flowing through the third pipe section... After passing through the tenth pipe 40 and / or the fourth pipe section and the section between the first end and the sixth connection point 351 of the third pipe 35, and the section between the sixth connection point 351 and its second end of the third pipe 35, the liquid flows into the heat exchanger 34. The cryogenic liquid absorbs heat from the air near the heat exchanger 34, cooling the air. The cooled air then cools the condenser 13, effectively reducing the condensing temperature, thereby reducing power consumption, increasing cooling capacity, improving energy efficiency, and making the unit operation more stable and reliable. The liquid flowing out of the heat exchanger 34 flows sequentially through the fourth pipe 36 and the sixth pipe 38 before returning to the liquid storage unit 30.

[0127] Optionally, the target area can be a computer room or an industrial area.

[0128] In practice, when the ambient temperature is low, there is no need to start the refrigerant circulation system 10, i.e., there is no need to start the compressor 14. The low-temperature liquid in the liquid storage component 30 can be used directly to cool the target area. After startup, the cooling component 33 and the liquid supply pump 372 start, the first control valve 311, the second control valve 321 and the fourth control valve 391 open, and the third control valve 361 closes. At this time, the unit operates in the second operating mode. In order to cool the target area more quickly, the first air blowing component 131 can be started simultaneously and blown towards the heat exchanger 34. The heat exchangers at both the liquid storage component 30 and the heat exchanger 34 start simultaneously, accelerating the cooling rate. Once the unit is running stably, only the heat exchanger at the liquid storage component 30 can be retained.

[0129] Specifically, the start-up temperature T1 is set. When the real-time temperature T0 ≤ T1, the start-up and operation of the refrigerant circulation system 10 are stopped, that is, the start-up and operation of the compressor 14 are stopped.

[0130] Specifically, the liquid storage component 30 is air-cooled with phase change heat transfer, which can keep the temperature of the circulating liquid lower than the dry-bulb temperature of the air.

[0131] Specifically, in the second operating mode, the heat exchanger 34 is an air-cooled conduction heat exchanger.

[0132] In practice, the unit can operate in the second operating mode more often, thereby reducing the operating opportunities of the compressor 14, reducing the unit's power consumption, and facilitating energy saving.

[0133] In the specific implementation process, when the circulating liquid flows into the inlet of the liquid storage component 30, it is guided by fine holes through the large area guide channel 3011 and then distributed to multiple distribution channels; when the liquid flows through the distribution channels, the distribution net 72 can also filter the liquid.

[0134] In the specific implementation process, during the operation of the liquid cooling circulation system 20, phenomena such as water dripping and evaporation may occur, causing the closed liquid cooling circulation system to experience pressure drop and insufficient liquid supply. The drop in water pressure will lead to a slower cooling of the target area; at this time, liquid can be replenished to the liquid cooling circulation system 20 through the liquid storage component 30.

[0135] In the specific implementation process, when the unit is operating in the second operating mode, water pressure is detected by water pressure detection device 223, and the frequency of liquid supply pump 372 is controlled to maintain good water pressure in liquid cooling circulation system 20. When the unit is to exit the second operating mode, since liquid cooling circulation system 20 has maintained good water pressure, and liquid supply pump 372 will not immediately stop at zero speed, in order to avoid the liquid supply pump 372 interfering with the already stable good water pressure, the first control valve 311, the second control valve 321 and the fourth control valve 391 are closed, and the third control valve 361 is opened, so that the liquid pumped by liquid supply pump 372 flows back to liquid storage component 30 through third pipeline 35, heat exchanger 34, fourth pipeline 36 and sixth pipeline 38, so that liquid supply pump 372 no longer interferes with the already stable water pressure in liquid cooling circulation system 20.

[0136] In this application, the control method applicable to the above-mentioned liquid-cooled unit includes:

[0137] The first pipeline 31 and the second pipeline 32 are both disconnected, and the refrigerant circulation system 10 is controlled to operate, so that the liquid chiller unit operates in the first operating mode.

[0138] The refrigerant circulation system 10 is kept off the machine, and the first pipe 31 and the second pipe 32 are kept in a connected state so that the liquid chiller unit can operate in the second operating mode.

[0139] In this application, when the liquid cooling unit is operating in the first operating mode, the control method further includes: controlling the third pipeline 35 and the fourth pipeline 36 to be in a connected state.

[0140] In this application, the control method further includes: when the liquid chiller unit operates in the first operating mode, controlling the seventh pipe 39 to be in a disconnected state, and controlling the pipe section between the third connection point 362 and its second end of the fourth pipe 36 to be in a connected state.

[0141] In this application, when the pressure of the liquid cooling circulation system 20 is adjusted to the preset water pressure, and when the liquid cooling unit is to exit the second operating mode, the control method further includes: controlling the third pipeline 35 to be in a connected state, controlling the seventh pipeline 39 to be in a disconnected state, and controlling the pipe section between the third connection point 362 and its second end of the fourth pipeline 36 to be in a connected state.
