The inlet end of the second heat exchange flow channel 210 is communicated with the outlet end of the first chamber 320, so that the adsorbate desorbed by heating in the first chamber 320 can flow into the second heat exchange flow channel 210 to be exothermically condensed in the second heat exchange flow channel 210, and the adsorbate after the exothermically condensed in the second heat exchange flow channel 210 can flow into the first heat exchange flow channel 210 to absorb heat and evaporate. In other words, when the coolant treatment system is in the first state, the coolant flowing out of the liquid cooling device 20 supplies heat to the first adsorber 300 to desorb the first adsorber 300, and the low-temperature medium output from the cold source device 30 supplies cold to the second adsorber 400 to adsorb the second adsorber 400.

When one of the adsorption process of the second adsorbent in the second chamber 420 and the desorption process of the first adsorbent in the first chamber 320 is completed, the coolant treatment system may be switched from the first state to the second state.

When the coolant treatment system is in the second state, the inlet end of the second heat exchanger 410 is in communication with the outlet end of the liquid cooling apparatus 20, so that the coolant flowing out of the liquid cooling apparatus 20 can flow into the second heat exchanger 410 to supply heat to the adsorbate in the second chamber 420. The inlet end of the first heat exchanger 310 communicates with the outlet end of the cold source device 30 such that a low-temperature medium output from the cold source device 30 may flow into the first heat exchanger 310 to cool the adsorbent in the first chamber 320. The outlet end of the first heat exchange flow passage 110 communicates with the inlet end of the first chamber 320, so that the evaporated adsorbent in the first heat exchange flow passage 110 can flow into the first chamber 320 to be adsorbed by the first adsorbent in the first chamber 320. The inlet end of the second heat exchange flow channel 210 is communicated with the outlet end of the second chamber 420, so that the adsorbate desorbed by heating in the second chamber 420 can flow into the second heat exchange flow channel 210 to be condensed by heat release in the second heat exchange flow channel 210, and the adsorbate after heat release and condensation in the second heat exchange flow channel 210 can flow into the first heat exchange flow channel 210 to absorb heat and evaporate. In other words, when the coolant treatment system is in the second state, the coolant flowing out of the liquid cooling device 20 supplies heat to the second adsorber 400 to desorb the second adsorber 400, and the low-temperature medium output from the cold source device 30 supplies cold to the first adsorber 300 to adsorb the first adsorber 300.

When one of the adsorption process of the first adsorbent in the first chamber 320 and the desorption process of the second adsorbent in the second chamber 420 is completed, the coolant treatment system may be switched from the second state to the first state.

In this way, the first adsorber 300 and the second adsorber 400 may be alternately adsorbed and desorbed by switching the coolant treatment system between the first state and the second state, and the first chamber 320 and the second chamber 420 may alternately supply the adsorbent to the condenser 200 and the evaporator 100 so that the adsorbent is continuously evaporated at the evaporator 100, so that continuous cooling may be performed by the evaporator 100.

The high temperature cooling liquid flowing out of the liquid cooling apparatus 20, which absorbs heat generated by the heat generating device, may be supplied to the first heat exchanger 310 or the second heat exchanger 410 as needed to desorb the adsorbent adsorbed by the first adsorbent in the first chamber 320 or to desorb the adsorbent adsorbed by the second adsorbent in the second chamber 420. The low-temperature medium output from the cold source device 30 may be supplied to the first heat exchanger 310 or the second heat exchanger 410 as needed so that the adsorbate in the first chamber 320 is adsorbed by the first adsorbent or the adsorbate in the second chamber 420 is adsorbed by the second adsorbent. The first adsorber 300 and the second adsorber 400 can alternately perform adsorption and desorption by the heat output from the liquid cooling device 20 and the cold output from the cold source device 30, so that the adsorbents are continuously supplied to the condenser 200 and the evaporator 100, and continuous refrigeration of the evaporator 100 is conveniently realized. In the refrigerating process of the evaporator 100, the heat desorbed by the adsorbents absorbed by the first adsorbent and the second adsorbent comes from the cooling liquid in the liquid cooling device 20, which absorbs the heat generated by the heating device, so that the heat in the cooling liquid flowing out of the liquid cooling device can be recycled, the heat recovery efficiency of the data center can be improved, and the waste of energy sources in the data center can be reduced.

In some examples, the first heat exchange flow channel 110, the second heat exchange flow channel 210, the first chamber 320 and the second chamber 420 are in a negative pressure environment, so that the adsorbed adsorbate is heated and vaporized, and then desorbed.

Illustratively, the adsorption refrigeration unit 50 may include a third reversing device 500 and a fourth reversing device 600.

For example, a fan blowing toward the first heat exchange flow path 110 may be provided at the evaporator 100, and the adsorbent evaporated in the first heat exchange flow path 110 may take away heat of air outside the first heat exchange flow path 110, so that cool air may be manufactured by the evaporator 100 and the fan.

The low temperature medium may be made by introducing a high temperature or normal temperature medium into the tenth heat exchange flow passage 120. For example, cold water may be produced by supplying normal-temperature water or high-temperature water into the tenth heat exchange flow passage 120.

For example, cold air, cold water, etc. produced by the evaporator 100 may be used for a cooling device of a data center, etc. that requires cold energy, to reduce energy consumption of the data center. Specifically, in some examples where a fan blowing air toward the first heat exchanging flow passage 110 is provided at the evaporator 100, cool air produced by the evaporator 100 and the fan may be blown into the machine room 10 to lower the temperature in the machine room 10, and thus heat generated in the machine room 10 may be taken away. That is, the cooling air made by the evaporator 100 may be utilized to cool the machine room 10. In some examples where the evaporator 100 includes the tenth heat exchange flow passage 120, the tenth heat exchange flow passage 120 may be in communication with the cold source device 30, and the low temperature medium made of the evaporator 100 may be used to dissipate heat from the medium flowing back to the cold source device 30 after absorbing the heat. For example, when the cold source device 30 is a cooling tower, the tenth heat exchange flow passage 120 may be in communication with a water distributor of the cooling tower.

For example, a fan blowing toward the second heat exchange flow path 210 may be provided at the condenser 200, and heat radiating fins may be provided on the outer wall of the second heat exchange flow path 210 so that the adsorbate in the second heat exchange flow path 210 may release heat.

The seventh heat exchange flow channel 220 has an inlet end and an outlet end, and the medium for exchanging heat with the adsorbate in the second heat exchange flow channel 210 flows into the seventh heat exchange flow channel 220 through the inlet end of the seventh heat exchange flow channel 220, and after exchanging heat with the adsorbate in the second heat exchange flow channel 210, flows out of the seventh heat exchange flow channel 220 through the outlet end of the seventh heat exchange flow channel 220.

In this way, the low-temperature medium flowing out of the cold source device 30 may flow into the seventh heat exchange flow channel 220 to absorb the heat of the adsorbate in the second heat exchange flow channel 210 after flowing through the first heat exchanger 310 or the second heat exchanger 410, so as to cool and condense the adsorbate in the second heat exchange flow channel 210, and then flow out of the seventh heat exchange flow channel 220 to flow back into the cold source device 30. In this way, the utilization rate of the low-temperature medium flowing out of the cold source device 30 is high, and the number of the auxiliary devices such as the pipelines in the data center and the use amount of the medium for cooling in the data center can be reduced.

When the coolant treatment system includes the second reversing device 800, the inlet end of the seventh heat exchange flow passage 220 is connected to the second reversing device 800, so that the second reversing device 800 is connected to the inlet end of the cold source apparatus 30 through the seventh heat exchange flow passage 220. The second reversing device 800 is used to communicate the outlet end of the first heat exchanger 310 with the inlet end of the cold source device 30 through the seventh heat exchange flow channel 220, or communicate the outlet end of the second heat exchanger 410 with the inlet end of the cold source device 30 through the seventh heat exchange flow channel 220. Specifically, the second reversing device 800 communicates the outlet end of the second heat exchanger 410 with the inlet end of the seventh heat exchange flow passage 220 when the coolant treatment system is in the first state. When the coolant treatment system is in the second state, the second reversing device 800 communicates the outlet end of the first heat exchanger 310 with the inlet end of the seventh heat exchange flow passage 220.

In other examples, the inlet and outlet ends of the seventh heat exchange flow passage 220 may also be in communication with the outlet and inlet ends of the cold source device 30 through pipes juxtaposed with the first and second heat exchangers 310 and 410, respectively, so that the cold source device 30 may supply a medium of a low temperature to the seventh heat exchange flow passage 220.

In some possible embodiments, the coolant treatment system further includes a first driving device 900, where the first driving device 900 is connected in series between the outlet end of the second heat exchange flow channel 210 and the inlet end of the first heat exchange flow channel 110, and the first driving device 900 is configured to enable the adsorbate in the second heat exchange flow channel 210 to flow to the first heat exchange flow channel 110.

In this way, the first driving device 900 may provide the power for flowing the adsorbate in the second heat exchange channel 210 to the first heat exchange channel 110, and may make the arrangement of the evaporator 100, the condenser 200, the first adsorber 300, and the second adsorber 400 flexible. In addition, the circulating flow of the adsorbent between the first heat exchange flow passage 110 and the second heat exchange flow passage 210 is also relatively stable.

By way of example, the first drive 900 may include, but is not limited to, a drive pump, a throttle valve, and the like.

For example, the first driving device 900 may be disposed at one side of the evaporator 100 and the condenser 200 in the length direction (see fig. 2).

In some examples, the evaporator 100 and the condenser 200 may be disposed side by side in a horizontal direction, and the evaporator 100 and the condenser 200 may be disposed below the first adsorber 300 and the second adsorber 400, and the adsorbent may circulate between the second heat exchange flow passage 210, the first heat exchange flow passage 110, the first chamber 320, and the second chamber 420 (see fig. 2) under the driving of the first driving device 900.

In other examples, the condenser 200 is disposed above the first adsorber 300 and the second adsorber 400, and the evaporator 100 is disposed below the first adsorber 300 and the second adsorber 400. In this way, after the adsorbate in the first heat exchange flow channel 110 evaporates, the adsorbate can flow into the first chamber 320 or the second chamber 420 under the action of self-elevating force, after the adsorbate adsorbed on the first adsorbate and the second adsorbate is heated and evaporated, the adsorbate can flow into the second heat exchange flow channel 210 under the action of self-elevating force, and after the adsorbate in the second heat exchange flow channel 210 condenses, the adsorbate can flow into the first heat exchange flow channel 110 under the action of self-elevating force, so that the circulation flow of the adsorbate between the first heat exchange flow channel 110 and the second heat exchange flow channel 210 can be realized.

As shown in fig. 3, in some possible embodiments, the coolant treatment system further includes a second driving device 60, an output end of the second driving device 60 is connected to an inlet end of the first heat exchanger 310 and an inlet end of the second heat exchanger 410, and an input end of the second driving device 60 is connected to an outlet end of the cold source apparatus 30, such that the inlet end of the first heat exchanger 310 and the inlet end of the second heat exchanger 410 are connected to the outlet end of the cold source apparatus 30 through the second driving device 60.

In this way, the second driving device 60 can provide power for flowing the medium in the cold source device 30 to the first heat exchanger 310 and the second heat exchanger 410, so that the medium flowing out of the cold source device 30 can flow in a stable and circulating manner.

By way of example, the second drive 60 may include, but is not limited to, a drive pump, a throttle valve, and the like.

When the cooling fluid treatment system comprises the first reversing device 700, the output end of the second driving device 60 is connected to the first reversing device 700, so that the first reversing device 700 is used for being connected to the outlet end of the cold source device 30 through the second driving device 60, and the second driving device 60 is used for enabling the medium in the cold source device 30 to flow to the first reversing device 700. The first reversing device 700 is used to communicate the inlet end of the first heat exchanger 310 with the outlet end of the cold source device 30 through the second driving device 60, or to communicate the inlet end of the second heat exchanger 410 with the outlet end of the cold source device 30 through the second driving device 60. Specifically, the first reversing device 700 communicates the inlet end of the second heat exchanger 410 with the output end of the second driving device 60 when the coolant treatment system is in the first state.

In some possible embodiments, the data center further includes a coolant distribution device 40 (coolant distribution units, CDU), the coolant distribution device 40 including an eighth heat exchange flow path 41, the coolant distribution device 40 operable to dissipate heat from coolant within the eighth heat exchange flow path 41. The eighth heat exchange flow channel 41 has an inlet end and an outlet end, the inlet end of the eighth heat exchange flow channel 41 is used for allowing the cooling liquid to flow into the eighth heat exchange flow channel 41 so as to radiate the cooling liquid in the eighth heat exchange flow channel 41, and the outlet end of the eighth heat exchange flow channel 41 is used for allowing the cooling liquid radiated in the eighth heat exchange flow channel 41 to flow out of the eighth heat exchange flow channel 41.

The outlet end of the eighth heat exchange flow channel 41 is communicated with the inlet end of the liquid cooling device 20, and the inlet end of the eighth heat exchange flow channel 41 is connected with the outlet end of the first heat exchanger 310 and the outlet end of the second heat exchanger 410, so that the outlet end of the first heat exchanger 310 and the outlet end of the second heat exchanger 410 are connected with the inlet end of the liquid cooling device 20 through the eighth heat exchange flow channel 41. When the cooling liquid treatment system is in the first state, the outlet end of the first heat exchanger 310 is communicated with the inlet end of the eighth heat exchange flow channel 41, so that the outlet end of the first heat exchanger 310 is communicated with the inlet end of the liquid cooling device 20 through the eighth heat exchange flow channel 41. When the coolant treatment system is in the second state, the outlet end of the second heat exchanger 410 is in communication with the inlet end of the eighth heat exchange flow channel 41, so that the outlet end of the second heat exchanger 410 is in communication with the inlet end of the liquid cooling apparatus 20 through the eighth heat exchange flow channel 41.

In this way, after the cooling liquid flowing out from the liquid cooling device 20 exchanges heat through the first heat exchanger 310 or the second heat exchanger 410, the cooling liquid can enter the cooling liquid distribution device 40 to further dissipate heat, so that the temperature of the cooling liquid flowing back to the liquid cooling device 20 meets the requirement of the liquid inlet temperature of the liquid cooling device 20.

By way of example, the coolant treatment system may include a coolant distribution device 40.

For example, the coolant treatment system may not include the coolant distribution device 40, and the coolant distribution device 40 may be independent of the coolant treatment system.

For example, a fan blowing air toward the cooling liquid distribution device 40 may be provided at the cooling liquid distribution device 40, and heat radiating fins may be provided on the outer wall of the eighth heat exchanging channel 41 so that the cooling liquid in the eighth heat exchanging channel 41 may release heat.

The second reversing device 800 is configured to communicate the outlet end of the first heat exchanger 310 with the inlet end of the liquid cooling apparatus 20 through the eighth heat exchange flow channel 41, or communicate the outlet end of the second heat exchanger 410 with the inlet end of the liquid cooling apparatus 20 through the inlet end of the eighth heat exchange flow channel 41. Specifically, the second reversing device 800 communicates the outlet end of the first heat exchanger 310 with the inlet end of the eighth heat exchange flow passage 41 when the coolant treatment system is in the first state. When the coolant treatment system is in the second state, the second reversing device 800 communicates the outlet end of the second heat exchanger 410 with the inlet end of the eighth heat exchange flow passage 41.

In some possible embodiments, the cooling liquid distribution device 40 further includes a ninth heat exchange flow channel 42, where the eighth heat exchange flow channel 41 and the ninth heat exchange flow channel 42 are isolated from each other, and the cooling liquid distribution device 40 is configured to exchange heat between the cooling liquid in the eighth heat exchange flow channel 41 and the medium in the ninth heat exchange flow channel 42, and may take away heat in the cooling liquid in the eighth heat exchange flow channel 41 by introducing the medium with a lower temperature into the ninth heat exchange flow channel 42, so that the cooling liquid in the eighth heat exchange flow channel 41 may release heat.

The ninth heat exchange flow passage 42 has an inlet end and an outlet end, a medium for taking away heat of the cooling liquid in the eighth heat exchange flow passage 41 flows into the ninth heat exchange flow passage 42 through the inlet end of the ninth heat exchange flow passage 42, and after heat exchange is performed between the medium in the ninth heat exchange flow passage 42 and the cooling liquid in the eighth heat exchange flow passage 41, the medium flows out of the ninth heat exchange flow passage 42 through the outlet end of the ninth heat exchange flow passage 42.

In some possible embodiments, the outlet end of the ninth heat exchange flow passage 42 is configured to communicate with the inlet end of the cold source device 30, and the inlet end of the ninth heat exchange flow passage 42 is configured to communicate with the outlet end of the cold source device 30.

In this way, the low-temperature medium can be supplied into the ninth heat exchange flow path 42 by the cold source device 30 that supplies the low-temperature medium to the first heat exchanger 310 or the second heat exchanger 410, that is, the same cold source device 30 can adsorb the first adsorber 300 or the second adsorber 400 and release the heat of the coolant in the eighth heat exchange flow path 41, so that the number of devices to be installed can be reduced.

In some possible embodiments, the first reversing device 700 includes a first four-way reversing valve 710. The first four-way reversing valve 710 includes a first port 711, a second port 712, a third port 713, and a fourth port 714, the first port 711 being in communication with an inlet end of the first heat exchanger 310, the second port 712 being in communication with an inlet end of the second heat exchanger 410, the third port 713 being for communication with an outlet end of the cold source device 30, and the fourth port 714 being for communication with an outlet end of the liquid cooling device 20. The first four-way reversing valve 710 is used to communicate the first port 711 with the third port 713, the second port 712 with the fourth port 714, or the first port 711 with the fourth port 714, the second port 712 with the third port 713. When the coolant treatment system is in the first state, the first four-way reversing valve 710 communicates the first port 711 with the fourth port 714 and the second port 712 with the third port 713. When the coolant treatment system is in the second state, the first four-way reversing valve 710 communicates the first port 711 with the third port 713, and the second port 712 with the fourth port 714.

Thus, the first reversing device 700 has a simpler structure and is more convenient to control.

In examples where the coolant treatment system includes the second drive 60, the third port 713 may be in communication with an output of the second drive 60 such that the third port 713 may be in communication with an output of the cold source apparatus 30 through the second drive 60.

The second four-way selector valve 810 is used to communicate the fifth port 811 with the seventh port 813, the sixth port 812 with the eighth port 814, or to communicate the fifth port 811 with the eighth port 814, and the sixth port 812 with the seventh port 813. When the coolant treatment system is in the first state, the second four-way selector valve 810 communicates the fifth port 811 with the eighth port 814 and the sixth port 812 with the seventh port 813. When the coolant treatment system is in the second state, the second four-way selector valve 810 communicates the fifth port 811 with the seventh port 813 and the sixth port 812 with the eighth port 814.

Thus, the second reversing device 800 has a simpler structure and is more convenient to control.

In an example in which the outlet end of the seventh heat exchange flow passage 220 communicates with the inlet end of the cold source apparatus 30, the seventh port 813 may communicate with the inlet end of the seventh heat exchange flow passage 220 such that the seventh port 813 may be used to communicate with the inlet end of the cold source apparatus 30 through the seventh heat exchange flow passage 220.

In the example in which the inlet end of the liquid cooling apparatus 20 communicates with the outlet end of the eighth heat exchanging channel 41, the eighth port 814 is for communicating with the inlet end of the eighth heat exchanging channel 41, so that the eighth port 814 can be for communicating with the inlet end of the liquid cooling apparatus 20 through the eighth heat exchanging channel 41.

In the example where the first reversing device 700 includes the first four-way reversing valve 710 and the second reversing device 800 includes the second four-way reversing valve 810, the cooling liquid flowing out of the liquid cooling apparatus 20 and the medium flowing out of the cold source apparatus 30 may be the same medium, for example, both may be water.

In some examples where the first reversing device 700 includes a first four-way reversing valve 710 and the second reversing device 800 includes a second four-way reversing valve 810, the first four-way reversing valve 710 and the second four-way reversing valve 810 may be fixedly disposed above the first adsorber 300 and the second adsorber 400. (see FIG. 2)

In some examples, the third reversing device 500 includes a ninth valve 510 and a tenth valve 520. An outlet end of the ninth valve 510 communicates with an inlet end of the first chamber 320, and an inlet end of the ninth valve 510 communicates with an outlet end of the first heat exchange flow passage 110. The outlet end of the tenth valve 520 communicates with the inlet end of the second chamber 420, and the inlet end of the tenth valve 520 communicates with the outlet end of the first heat exchange flow passage 110.

When the coolant treatment system is in the first state, that is, when the second adsorber 400 adsorbs and the first adsorber 300 desorbs, the ninth valve 510 may be closed and the tenth valve 520 may be opened, so that the adsorbent flowing out of the first heat exchange flow passage 110 may enter the second chamber 420 and be adsorbed by the second adsorbent. When the coolant treatment system is in the second state, that is, the first adsorber 300 is adsorbing and the second adsorber 400 is desorbing, the ninth valve 510 may be opened and the tenth valve 520 may be closed, so that the adsorbent flowing out of the first heat exchange flow passage 110 may enter the first chamber 320 to be adsorbed by the first adsorbent.

By providing a ninth valve 510 and a tenth valve 520 to control the reversing, control of the inlet end of the first chamber 320 and the inlet end of the second chamber 420 may be more flexible. For example, in some specific scenarios, the ninth valve 510 and the tenth valve 520 are closed or opened simultaneously, or after one of the ninth valve 510 and the tenth valve 520 is completely closed or completely opened, the other of the ninth valve 510 and the tenth valve 520 is opened or closed.

In some possible embodiments, the fourth reversing device 600 includes an eleventh valve 610 and a twelfth valve 620. An inlet end of the eleventh valve 610 communicates with an outlet end of the first chamber 320, and an outlet end of the eleventh valve 610 communicates with an inlet end of the second heat exchange flow passage 210. An inlet end of the twelfth valve 620 communicates with an outlet end of the second chamber 420, and an outlet end of the twelfth valve 620 communicates with an inlet end of the second heat exchange flow passage 210.

When the coolant treatment system is in the first state, that is, when the second adsorber 400 is adsorbing and the first adsorber 300 is desorbing, the eleventh valve 610 may be opened and the twelfth valve 620 may be closed, so that the adsorbent desorbed from the first adsorbent may flow from the first chamber 320 into the second heat exchange flow path 210. When the coolant treatment system is in the second state, that is, when the first adsorber 300 performs adsorption and the second adsorber 400 performs desorption, the eleventh valve 610 may be closed and the twelfth valve 620 may be opened, so that the adsorbent desorbed from the second adsorbent may flow from the second chamber 420 into the second heat exchange flow channel 210.

By providing the eleventh valve 610 and the twelfth valve 620 to control the reversing, the control of the outlet end of the first chamber 320 and the outlet end of the second chamber 420 may be made more flexible. For example, in certain circumstances, the eleventh valve 610 and the twelfth valve 620 may be closed or opened simultaneously, or one of the eleventh valve 610 and the twelfth valve 620 may be fully closed or fully opened before the other of the eleventh valve 610 and the twelfth valve 620 is opened or closed.

If the ninth valve 510, the tenth valve 520, the eleventh valve 610 and the twelfth valve 620 are provided, if the first adsorber 300 fails, the ninth valve 510 and the eleventh valve 610 may be closed simultaneously to isolate the first adsorber 300 for maintenance or the like of the first adsorber 300. If the second adsorber 400 fails, the tenth valve 520 and the twelfth valve 620 may be closed simultaneously to isolate the second adsorber 400 for maintenance or the like of the second adsorber 400.

Illustratively, the ninth valve 510, the tenth valve 520, the eleventh valve 610, and the twelfth valve 620 may each be a vacuum valve to be suitable for use in a negative pressure environment.

In other examples, the third reversing device 500 may include a first three-way reversing valve, where three ports of the first three-way reversing valve are respectively communicated with the inlet end of the first chamber 320, the inlet end of the second chamber 420, and the outlet end of the first heat exchange flow channel 110, and the inlet end of the first chamber 320 may be communicated with the outlet end of the first heat exchange flow channel 110, or the inlet end of the second chamber 420 may be communicated with the outlet end of the first heat exchange flow channel 110 by controlling the on-off of the flow path between the three ports of the first three-way reversing valve. Specifically, the first three-way reversing valve communicates the port connecting the inlet end of the second chamber 420 with the port connecting the outlet end of the first heat exchange flow passage 110 when the coolant treatment system is in the first state. The first three-way reversing valve communicates a port connected to the inlet end of the first chamber 320 with a port connected to the outlet end of the first heat exchange flow passage 110 when the coolant treatment system is in the second state.

Thus, the structure of the third reversing device 500 is simpler and the control is more convenient.

The fourth reversing device 600 may include a second three-way reversing valve, where three ports of the second three-way reversing valve are respectively communicated with the outlet end of the first chamber 320, the outlet end of the second chamber 420 and the inlet end of the second heat exchange flow channel 210, and the outlet and inlet ends of the first chamber 320 and the inlet end of the second heat exchange flow channel 210 may be communicated by controlling the on-off of the flow path between the three ports of the second three-way reversing valve, or the outlet end of the second chamber 420 and the inlet end of the second heat exchange flow channel 210. Specifically, the second three-way reversing valve communicates a port connected to the outlet end of the first chamber 320 with a port connected to the inlet end of the second heat exchange flow path 210 when the coolant treatment system is in the first state. In the second state of the coolant treatment system, the second three-way reversing valve communicates the port connected to the outlet end of the second chamber 420 with the port connected to the inlet end of the first heat exchange flow passage 110. Thus, the fourth reversing device 600 can be simpler in structure and more convenient to control.

When the medium from the cold source device 30 flows through the third heat exchange flow channel 311 and the cooling liquid from the liquid cooling device 20 flows through the sixth heat exchange flow channel 412, the medium flowing out of the third heat exchange flow channel 311 can flow back to the cold source device 30 and the cooling liquid flowing out of the sixth heat exchange flow channel 412 can flow back to the liquid cooling device 20 by opening the fifth valve 820 and the eighth valve 850 and closing the sixth valve 830 and the seventh valve 840. When the medium from the cold source device 30 flows through the fifth heat exchange flow channel 411 and the cooling liquid from the liquid cooling device 20 flows through the fourth heat exchange flow channel 312, the medium flowing out of the fifth heat exchange flow channel 411 may flow back to the cold source device 30 and the cooling liquid flowing out of the fourth heat exchange flow channel 312 may flow back to the liquid cooling device 20 by opening the sixth valve 830 and the seventh valve 840 and closing the fifth valve 820 and the eighth valve 850.

In some possible embodiments, the second reversing device 800 further includes a fifth line 860, a sixth line 870, a seventh line 880, and an eighth line 890. One end of the fifth pipeline 860 is communicated with the outlet end of the third heat exchange flow channel 311, the other end of the fifth pipeline 860 is used for being communicated with the inlet end of the cold source device 30, and a fifth valve 820 is arranged on the fifth pipeline 860.

When the first heat exchanger 310 includes the third heat exchange flow path 311 and the fourth heat exchange flow path 312, the second heat exchanger 410 includes the fifth heat exchange flow path 411 and the sixth heat exchange flow path 412, the first reversing device 700 includes the first valve 720, the second valve 730, the third valve 740 and the fourth valve 750, and the second reversing device 800 includes the fifth valve 820, the sixth valve 830, the seventh valve 840 and the eighth valve 850, the cooling liquid from the liquid cooling apparatus 20 and the medium from the cold source apparatus 30 have separate flow paths, respectively, in the process of alternately adsorbing and desorbing the first adsorber 300 and the second adsorber 400, and the cooling liquid from the liquid cooling apparatus 20 and the medium from the cold source apparatus 30 are not easy to pollute each other, so that the restriction on the type of selection of the cooling liquid flowing out of the liquid cooling apparatus 20 and the medium flowing out of the cold source apparatus 30 is small. At this time, the cooling liquid flowing out of the liquid cooling apparatus 20 and the medium flowing out of the cold source apparatus 30 may be different mediums, for example, the cooling liquid flowing out of the liquid cooling apparatus 20 may be a fluorinated liquid, and the medium flowing out of the cold source apparatus 30 may be water. Of course, the cooling liquid flowing out of the liquid cooling device 20 and the medium flowing out of the cold source device 30 may be the same medium, for example, both the cooling liquid flowing out of the liquid cooling device 20 and the medium flowing out of the cold source device 30 may be water, so that the standard of the water flowing out of the liquid cooling device 20 is higher than that of the water flowing out of the cold source device 30, and thus the liquid cooling device 20 is not easy to be blocked, and the cost of the medium used in the cold source device 30 is low.
