With reference to fig. 1 to 3, an embodiment of the present disclosure provides a liquid cooling unit, including: evaporator 200, condenser 300, liquid return line 400, and liquid outlet line 500. The return line 400 includes a first flow path 410 and a second flow path 420, the first flow path 410 flowing through the evaporator 200, the second flow path 420 flowing through the condenser 300; the liquid outlet pipe 500 is respectively communicated with the liquid outlet ends of the first flow path 410 and the second flow path 420, and the heat exchange medium circulates along the liquid return pipe 400 and the liquid outlet pipe 500.
By adopting the liquid cooling unit provided by the embodiment of the disclosure, the heat exchange medium flows out from the liquid outlet pipe 500 to cool and radiate a module which needs to be cooled, the heat exchange medium with the increased temperature flows in from the liquid return pipe 400, and flows through the evaporator 200 through the first flow path 410 to cool and then flows out from the liquid outlet pipe 500 again to cool and radiate. When the ambient temperature that this liquid cooling unit is located is lower, the heat transfer medium circulation under the low temperature environment this moment probably receives the influence, consequently selectively controls heat transfer medium's flow direction, makes heat transfer medium flow through condenser 300 through second flow path 420 when the low temperature uses, utilizes condenser 300 to heat transfer medium, and the guarantee heat transfer medium can unobstructed circulation, has reduced the energy consumption, has reduced the cost of this liquid cooling unit. Heat transfer medium through condenser 300 under to low temperature environment heats to according to ambient temperature control heat transfer medium's flow direction, can accurately adjust heat transfer medium's under the low temperature environment temperature, ensure heat transfer medium's cooling effect.
Optionally, the liquid cooling unit further comprises: a compressor 600. The compressor 600 has an exhaust pipe communicating with an input end of the condenser 300 and a return pipe communicating with an output end of the evaporator 200. In this way, the refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant by the compressor 600, and the high-temperature and high-pressure gaseous refrigerant is discharged into the condenser 300 through the discharge pipe, and condenses and releases heat in the condenser 300. When the liquid cooling unit operates in a low-temperature environment, the heat exchange medium flows through the condenser 300 through the second flow path 420, and the condenser 300 heats the flowing heat exchange medium, so that the normal circulation of the heat exchange medium is guaranteed. The condensing temperature of the condenser 300 is adjusted to accurately control the heating temperature of the heat exchange medium, so that the heat exchange medium in a low-temperature environment can be heated, and the cooling and heat dissipation effects of the heat exchange medium due to the fact that the heating temperature is too high can be avoided. The refrigerant after heat release from condensation flows to the evaporator 200 to evaporate and absorb heat, the temperature of the heat exchange medium flowing back through the liquid return pipeline 400 is raised, the heat exchange medium is controlled to flow through the evaporator 200 through the first flow path 410 in a non-low temperature environment, and the heat of the heat exchange medium is absorbed by the evaporator 200, so that the heat exchange medium can flow out again to cool and dissipate heat.
Specifically, the output of the condenser 300 is in communication with the input of the evaporator 200. In this way, the refrigerant condensed and released in the condenser 300 flows from the output end to the input end of the evaporator 200, the refrigerant flowing into the evaporator 200 evaporates in the evaporator 200 to absorb heat, and the evaporated and heat-absorbed gaseous refrigerant flows into the compressor 600 from the return pipe to be compressed again, thereby completing one refrigerant cycle.
Specifically, a throttling device 700 is communicated between the output end of the condenser 300 and the input end of the evaporator 200. In this way, the refrigerant flowing out of the condenser 300 is throttled and depressurized by the throttle device 700, so that the refrigerant flowing into the evaporator 200 is better evaporated and absorbs heat.
Specifically, the heat exchange medium is water, and the liquid cooling unit is a water cooling unit.
Optionally, as shown in fig. 2, the liquid cooling unit further includes: cooling circuit 800. Cooling pipeline 800 sets up in equipment for cool down to equipment, and the one end of cooling pipeline 800 is linked together and is gone out liquid pipeline 500, and the other end communicates return liquid pipeline 400, and heat transfer medium circulates among cooling pipeline 800, return liquid pipeline 400 and play liquid pipeline 500. In this way, the heat exchange medium flowing out of the liquid outlet pipe 500 flows into the cooling pipe 800, and because the cooling pipe 800 is arranged in the device requiring heat dissipation and temperature reduction, the heat exchange medium flowing into the cooling pipe 800 absorbs heat generated by the device, so as to cool and dissipate the heat of the device. The heat exchange medium absorbing heat flows into the liquid return pipeline 400, flows into the evaporator 200 through the first flow path 410 to be cooled and refrigerated, and then flows into the cooling pipeline 800 again to be cooled and radiated. However, when the ambient temperature is low, the heat exchange medium may flow into the condenser 300 through the second flow path 420 to be heated, thereby ensuring smooth circulation of the heat exchange medium.
It can be understood that the equipment is heating equipment such as a server and a terminal in a machine room, and the cooling pipeline 800 can be arranged in the equipment and also can be arranged in the machine room to cool the environment in the machine room.

In this way, the three-way solenoid valve 440 controls the opening and closing of the first flow path 410 and the second flow path 420, so as to more precisely control the flow direction of the heat exchange medium in the main liquid return pipe 430. When the heat exchange medium in the main liquid return pipe 430 needs to be controlled to flow to the evaporator 200 for cooling, the three-way electromagnetic valve 440 is controlled to conduct the first flow path 410 and block the second flow path 420, so that the heat exchange medium in the main liquid return pipe 430 flows to the evaporator 200 for cooling. When the heat exchange medium in the main liquid return pipe 430 needs to be controlled to flow to the condenser 300 for heating, the three-way solenoid valve 440 is controlled to block the first flow path 410 and conduct the second flow path 420, so that the heat exchange medium in the main liquid return pipe 430 flows to the condenser 300 for heating.
Specifically, the three-way valve has an input end and two output ends, the input end is communicated with the liquid outlet end of the main liquid return pipe 430, one of the two output ends is communicated with the liquid inlet end of the first flow path 410, and the other output end is communicated with the liquid inlet end of the second flow path 420.
Optionally, as shown in fig. 1, the liquid cooling unit further includes: a temperature sensor 900. The temperature sensor 900 is disposed in the environment where the evaporator 200 is located, and the temperature sensor 900 is electrically connected to the three-way electromagnetic valve 440. Therefore, the temperature sensor 900 can acquire the ambient temperature in real time, and the conduction state of the three-way electromagnetic valve 440 is controlled according to the ambient temperature, so as to control the flow direction of the heat exchange medium in the main liquid return pipe 430. Because the evaporator 200 is used for cooling and refrigerating the heat transfer medium, the temperature sensor 900 is arranged in the environment where the evaporator 200 is located, and the temperature sensor 900 is used for detecting the ambient temperature where the evaporator 200 is located in real time, so that the heat transfer medium is not required to be heated when the ambient temperature where the heat transfer medium is located is judged more accurately.

Like this, set up the refrigerant coil pipe of evaporator 200 to first outer pipe 210 parcel first inlayer pipe 220, refrigerant among the evaporator 200 circulates in first circulation space 230, and heat transfer medium circulates in first inlayer pipe 220, makes the endothermic refrigerant of evaporation form the effect of parcel to heat transfer medium, improves heat transfer area and heat exchange efficiency. When the heat transfer medium needs to flow through the evaporator 200 for cooling, the cooling efficiency of the heat transfer medium can be improved.
Optionally, the first outer layer tube 210 and the first inner layer tube 220 are both round tubes, and the first outer layer tube 210 and the first inner layer tube 220 are concentrically arranged.

Illustratively, when flowing through the evaporator 200, the heat exchange medium flowing through the first flow path 410 firstly flows into the liquid inlet end of the first inner-layer tube 220, and then flows out of the liquid outlet end of the first inner-layer tube 220 into the first flow path 410 again, and the heat exchange medium participates in heat exchange during the whole process when flowing through the evaporator 200.
Optionally, the refrigerant coil of the condenser 300 is divided into a second outer tube 310 and a second inner tube 320, the second outer tube 310 is sleeved on the periphery of the second inner tube 320, a second circulation space 330 is defined between the inner circumferential wall of the second outer tube 310 and the outer circumferential wall of the second inner tube 320, the refrigerant of the condenser 300 circulates in the second circulation space 330, and the second inner tube 320 is communicated with the second flow path 420.

When the heat exchange medium needs to flow through the condenser 300 for condensation, the heating efficiency of the heat exchange medium can be improved.
Optionally, the second outer tube 310 and the second inner tube 320 are both round tubes, and the second outer tube 310 and the second inner tube 320 are concentrically disposed. In this way, the second circulation space 330 defined between the inner peripheral wall of the second outer tube 310 and the outer peripheral wall of the second inner tube 320 is more uniform, and the refrigerant more smoothly circulates in the second circulation space 330, so as to better exchange heat with the heat exchange medium circulating in the second inner tube 320.
For example, when flowing through the condenser 300, the heat exchange medium flowing through the second flow path 420 firstly flows into the liquid inlet end of the second inner-layer tube 320, and then flows out of the liquid outlet end of the second inner-layer tube 320 into the second flow path 420 again, and the heat exchange medium participates in heat exchange in the whole process when flowing through the condenser 300.

Referring to fig. 6, in some optional embodiments, a method for controlling a liquid cooling unit includes:
s01, the processor obtains the ambient temperature of the liquid cooling unit;
s022, controlling the heat exchange medium to flow to the condenser by the processor under the condition that the ambient temperature is lower than a first set temperature.
By adopting the control method of the liquid cooling unit provided by the embodiment of the disclosure, when the obtained ambient temperature is lower than the first set temperature, the ambient temperature is lower at the moment, and the heat exchange medium in the liquid cooling unit has the risk of condensation, so that the heat exchange medium is controlled to flow to the condenser for heating, and the smooth circulation of the heat exchange medium is ensured. Since the ambient temperature is low at this time, the heat exchange medium heated even by the condenser is much lower than the temperature inside the apparatus, thereby dissipating heat from the apparatus while flowing through the cooling line arranged inside the apparatus.
Specifically, the treater control heat transfer medium flow to the condenser includes: the processor controls the three-way electromagnetic valve in the liquid return pipeline to be in a second conduction state. In this way, the three-way solenoid valve blocks the first flow path and conducts the second flow path in the second conduction state, so that the heat exchange medium flows into the condenser through the second flow path to be heated.
Specifically, the first set temperature is 2 ℃. Therefore, when the ambient temperature is greater than or equal to 2 ℃, the heat exchange medium has no condensation risk, and the heat exchange medium after absorbing heat is controlled to flow to the evaporator to be cooled. When the ambient temperature is less than 2 ℃, the heat exchange medium has a condensation risk, so that the heat exchange medium after absorbing heat is controlled to flow to the condenser for heating.
Referring to fig. 7, in some optional embodiments, a method for controlling a liquid cooling unit includes:
s01, the processor obtains the ambient temperature of the liquid cooling unit;
s022, controlling a heat exchange medium to flow to a condenser by a processor under the condition that the ambient temperature is lower than a first set temperature;
s03, the processor determines the magnitude relation between the environment temperature and a second set temperature;
s04, controlling the compressor of the liquid cooling unit to stop by the processor under the condition that the ambient temperature is greater than or equal to a second set temperature;
wherein the second set temperature is less than the first set temperature.
By adopting the control method of the liquid cooling unit provided by the embodiment of the disclosure, the processor determines the magnitude relation between the ambient temperature and the second set temperature again after controlling the heat exchange medium to flow to the condenser. Because the second set temperature is less than the first set temperature, when the environment temperature is greater than or equal to the second set temperature and less than the first set temperature, the environment temperature is relatively low, but the risk of condensation of the heat exchange medium is low, and the heat exchange medium is not required to be heated. The heat exchange medium can be cooled by relatively low ambient temperature, so that the compressor is controlled to stop, and the heat exchange medium is cooled by ambient heat exchange when flowing through the condenser, so that the cooling and heat dissipation effects of the heat exchange medium are guaranteed, and the energy consumption is further reduced.
Optionally, the processor controls the compressor of the liquid cooling unit to stop and controls the rotation speed of the condensing fan to increase when the ambient temperature is greater than or equal to the second set temperature. Therefore, when the processor controls the compressor to stop, the rotating speed of the condensing fan is controlled to be increased for improving the heat exchange efficiency of the heat exchange medium flowing through the condenser and exchanging heat with the environment, so that the heat exchange between the heat exchange medium and the environment in the condenser is accelerated, and the cooling efficiency of the heat exchange medium is improved.
Specifically, the second set temperature is-6 ℃. In this way, in the case of an ambient temperature greater than or equal to-6 ℃, the risk of condensation of the heat exchange medium is relatively low, and the compressor shutdown can be controlled for reducing energy consumption. Under the condition that the ambient temperature is less than minus 6 ℃, the ambient temperature is lower, and the condensation risk of the heat exchange medium is relatively higher.
Referring to fig. 8, in some optional embodiments, a method for controlling a liquid cooling unit includes:
s01, the processor obtains the ambient temperature of the liquid cooling unit;
s022, controlling a heat exchange medium to flow to a condenser by a processor under the condition that the ambient temperature is lower than a first set temperature;
s03, the processor determines the magnitude relation between the environment temperature and a second set temperature;
and S05, controlling the compressor of the liquid cooling unit to operate at the set power by the processor under the condition that the ambient temperature is lower than the second set temperature.
By adopting the control method of the liquid cooling unit provided by the embodiment of the disclosure, the processor determines the size relationship between the ambient temperature and the second set temperature after controlling the heat exchange medium to flow to the condenser, and when the ambient temperature is lower than the second set temperature, the condensation risk of the heat exchange medium is higher, so that the compressor is controlled to operate, the heat exchange medium flowing through the condenser is heated, and the smooth circulation of the heat exchange medium is ensured. Because the heat transfer medium behind the condenser of flowing through needs flow direction equipment to cool down the heat dissipation, therefore the heating temperature of condenser should not be too high, consequently control compressor is with setting for the power operation, makes the condenser can enough carry out appropriate heating to heat transfer medium, guarantees the smooth and easy nature of its circulation, can ensure again that heat transfer medium still has better cooling radiating effect after being heated.
Specifically, in the case where the compressor is operated at a set power, the temperature of the heat exchange medium after passing through the condenser fluctuates within a range of 6 ℃ or more and 10 ℃ or less. Therefore, the temperature of the heat exchange medium heated by the condenser is between 6 and 10 ℃, and the heat exchange medium has good circulation and better cooling and radiating effects.
