The adsorber 300 includes a heat exchanger disposed within the adsorption chamber for providing cold or heat to the adsorbent within the adsorption chamber to cause the adsorbent to be adsorbed by and desorbed from the adsorbent within the adsorption chamber.
Exemplary adsorbents may include, but are not limited to, cooling water, cooling oil, and the like.
By way of example, the adsorbent may comprise one or more of the following: activated carbon, silica gel, metal organic frameworks (metal organic frameworks, MOF), activated alumina, and the like.
The adsorption refrigeration device 50 further includes a condenser 200, the condenser 200 has an inlet end and an outlet end, the condenser 200 includes a condensation chamber, the inlet end of the condenser 200 and the outlet end of the condenser 200 are both communicated with the condensation chamber, the inlet end of the condenser 200 is used for allowing the adsorbate to flow into the condensation chamber so as to make the adsorbate exothermically condense in the condensation chamber, and the outlet end of the condenser 200 is used for allowing the adsorbate condensed in the condensation chamber to flow out of the condensation chamber. The condenser 200 includes a cooling member disposed in the condensing chamber for absorbing heat from the adsorbate in the condensing chamber to exothermically condense the adsorbate in the condensing chamber.
The outlet end of the adsorber 300 is connected to the inlet end of the condenser 200 so that the adsorbate desorbed in the adsorption chamber may flow into the condensing chamber for condensation.
By way of example, the cooling member may include heat exchange tubes or the like for passing a heat exchange medium therethrough.
The adsorption refrigeration device 50 also includes an evaporator 100, the evaporator 100 having an inlet end and an outlet end. The evaporator 100 includes an evaporation cavity, an inlet end of the evaporator 100 and an outlet end of the evaporator 100 are both communicated with the evaporation cavity, the inlet end of the evaporator 100 is used for allowing the adsorbate to flow into the evaporation cavity so as to enable the adsorbate to absorb heat and evaporate in the evaporation cavity, and the outlet end of the evaporator 100 is used for allowing the adsorbate evaporated in the evaporation cavity to flow out of the evaporation cavity. The evaporator 100 includes a heat supply part provided in the evaporation chamber, and absorbs heat of the heat supply part when the liquid adsorbent in the evaporation chamber evaporates, so that the heat supply part can be used for cooling.
The outlet end of the condenser 200 is connected to the inlet end of the evaporator 100, so that the adsorbate condensed by the condenser 200 can flow into the evaporation chamber for evaporation.
By way of example, the heat supply means may comprise heat exchange tubes or the like for the flow of a heat exchange medium.
The adsorber 300 may alternately heat and cool the adsorbents in the adsorption chambers by alternately supplying a high temperature medium and a low temperature medium into the heat exchanger, so that the adsorbents in the adsorption chambers may alternately desorb and adsorb, the desorbed adsorbents may flow into the condensation chambers from the adsorption chambers, the adsorbents flowing into the condensation chambers from the adsorption chambers may enter the evaporation chambers after being condensed into a liquid state by the condenser 200 in the condensation chambers, and the evaporator 100 may evaporate the adsorbents in the liquid state in the evaporation chambers, thereby realizing refrigeration.
In order to enable continuous cooling of the evaporator 100, the adsorption refrigeration device 50 may include two adsorbers 300, and the outlet ends of the two adsorbers 300 are connected to the inlet end of the condenser 200, so that continuous cooling of the evaporator 100 may be achieved by alternately supplying the two adsorbers 300 with the adsorbent to the condenser 200. Specifically, when one of the two adsorbers 300 is desorbed to supply the adsorbent to the condenser 200, the other adsorber 300 is adsorbed to store the adsorbent, and when the desorption process of the desorbed adsorber 300 is completed or the adsorption process of the adsorbed adsorber 300 is completed, the currently desorbed adsorber 300 is switched to adsorb to store the adsorbent, and the currently adsorbed adsorber 300 is switched to desorb to supply the adsorbent to the condenser 200, so that the adsorbent is continuously supplied to the condenser 200, the adsorbent is continuously evaporated in the evaporation chamber, and the evaporator 100 is continuously cooled.
The inlet ends of the two adsorbers 300 may be connected to the outlet end of the evaporator 100, so that the gaseous adsorbent flowing out of the evaporation chamber may flow into the adsorption chamber of the adsorber 300 for adsorption to be adsorbed by the adsorbent, and thus, recycling of the adsorbent may be achieved.
Illustratively, the evaporating chamber, condensing chamber and adsorbing chamber may be in a negative pressure environment, which facilitates heated evaporation of the adsorbate.
In order to enable the adsorbent between the outlet end of the condenser 200 and the inlet end of the evaporator 100 to flow smoothly and stably into the evaporation chamber, the adsorption refrigeration device 50 may further include a first driving device 400 disposed between the outlet end of the condenser 200 and the inlet end of the evaporator 100, where the outlet end of the condenser 200 is connected to the inlet end of the evaporator 100 through the first driving device 400, and the first driving device 400 is used for driving the adsorbent at the inlet end of the first driving device 400 to flow toward the inlet end of the evaporator 100.
In this way, the adsorbate in the condensation chamber may flow to the inlet end of the evaporator 100 under the driving of the first driving device 400, after the adsorbate in the condensation chamber flows out, the pressure in the condensation chamber is reduced, and the adsorbate may be sucked into the condensation chamber from the outlet end of the adsorber 300 that performs desorption, so the arrangement positions of the evaporator 100, the condenser 200 and the adsorber 300 may be more flexible. In addition, the adsorbate flows relatively stably toward the inlet end of the evaporator 100 under the driving of the first driving device 400, so that the problem that the adsorbate is difficult to flow from the inlet end of the evaporator 100 due to the large pressure in the evaporation cavity is not easy to occur, and the problem that evaporation efficiency of the evaporator 100 is reduced due to the difficulty in flowing of the adsorbate is not easy to occur.
By way of example, the first drive means 400 may include, but is not limited to, a drive pump, a throttle valve, and the like. When the first driving device 400 is a driving pump, the driving pump may be a constant frequency pump or a variable frequency pump.
Illustratively, both the evaporator 100 and the condenser 200 are disposed below the adsorber 300. In this way, the adsorber 300 does not need to support the evaporator 100 and the condenser 200, so that the requirement on the structural strength of the adsorber 300 is low, and a door opening with a larger size is formed on the side surface of the adsorber 300, so that articles such as a heat exchanger, an adsorbent and the like can be assembled in the adsorption cavity. In addition, the spacing between the evaporator 100 and the condenser 200 and the bearing surface for supporting the adsorption refrigeration device 50 is smaller, and the requirement for structural strength of the portion of the adsorption refrigeration device 50 for supporting the evaporator 100 and the condenser 200 is lower, so that the number of structural members of the portion of the adsorption refrigeration device 50 for supporting the evaporator 100 and the condenser 200 is smaller, the thickness is thinner, and the size of the adsorption refrigeration device 50 is further reduced.
In the embodiment of the application, the heat exchanger is provided with an inlet end and an outlet end, the inlet end of the heat exchanger is used for flowing high-temperature medium or low-temperature medium into the heat exchanger, the medium flowing into the heat exchanger can be used for carrying out heat exchange with the adsorbate in the adsorption cavity, and the outlet end of the heat exchanger is used for flowing out of the heat exchanger after carrying out heat exchange with the adsorbate in the adsorption cavity.
The inlet end of the heat exchanger is connected with the outlet end of the heat supply equipment and the outlet end of the cold source equipment, the outlet end of the heat supply equipment is used for enabling the high-temperature medium to flow out of the heat supply equipment, the high-temperature medium flowing out of the outlet end of the heat supply equipment can flow into the heat exchanger through the inlet end of the heat exchanger, and the high-temperature medium flowing into the heat exchanger can provide heat for the adsorbent in the adsorption cavity so that the adsorbent is desorbed from the adsorbent. The outlet end of the cold source equipment is used for allowing the low-temperature medium to flow out of the cold source equipment, the low-temperature medium flowing out of the outlet end of the cold source equipment can flow into the heat exchanger through the inlet end of the heat exchanger, and the low-temperature medium flowing into the heat exchanger can provide cold for the adsorbate in the adsorption cavity so that the adsorbate is adsorbed by the adsorbate.
By way of example, the heating equipment may include, but is not limited to, liquid cooling equipment that is a hot water tank, a data center, and the like.
By way of example, the cold source device may include, but is not limited to, a cooling tower, a cold water main, and the like.
In the related art, the outlet end of the heat supply device and the outlet end of the cold source device are connected to the same heat exchange flow passage of the heat exchanger, that is, when the adsorber alternately performs desorption and adsorption, the high temperature medium from the heat supply device and the low temperature medium from the cold source device alternately flow through the same heat exchange flow passage of the heat exchanger, residues are generated in the heat exchange flow passage when the high temperature medium from the heat supply device and the low temperature medium from the cold source device flow through the heat exchange flow passage, the high temperature medium from the heat supply device and the low temperature medium from the cold source device may be different mediums, or the quality standards of the high temperature medium from the heat supply device and the low temperature medium from the cold source device may be different, so that the medium from the heat supply device and the medium from the cold source device are liable to be contaminated with each other.
Based on the above, the embodiment of the application provides a heat exchanger, which comprises two heat exchange channels isolated from each other, wherein the inlet end of one heat exchange channel is used for being connected with the outlet end of heating equipment, and the inlet end of the other heat exchange channel is used for being connected with the outlet end of cold source equipment. Therefore, when the adsorber alternately carries out desorption and adsorption, the high-temperature medium from the heat supply equipment and the low-temperature medium from the cold source equipment respectively flow through two heat exchange channels which are isolated from each other in the heat exchanger, so that the medium from the heat supply equipment and the medium from the cold source equipment are not easy to pollute each other.
The embodiment of the application is described by taking a heat supply device as a liquid cooling device as an example, and the liquid cooling device can be a liquid cooling device of a data center. When the heat supply equipment is other equipment such as a hot water tank, the scheme that the heat supply equipment is liquid cooling equipment can be referred to for setting.

For example, the heat supply part may include a first heat exchange pipe including the third heat exchange flow passage 120, and a surface of the first heat exchange pipe may have first heat exchange fins. The evaporator 100 may be configured to make a low-temperature medium by introducing a high-temperature or normal-temperature medium into the third heat exchange flow passage 120.

For example, the cooling member may include a second heat exchange tube including a fourth heat exchange flow passage 220, and a surface of the second heat exchange tube may have second heat exchange fins.
The fourth heat exchange flow channel 220 has an inlet end and an outlet end, and the medium for exchanging heat with the adsorbate in the condensation chamber 210 flows into the fourth heat exchange flow channel 220 through the inlet end of the fourth heat exchange flow channel 220, and after exchanging heat with the adsorbate in the condensation chamber 210, flows out of the fourth heat exchange flow channel 220 through the outlet end of the fourth heat exchange flow channel 220.

In this way, both the first heat exchange plate 731 and the second heat exchange plate 741 can exchange heat with the adsorbent through the third heat exchange fins 761, so that the heat exchange efficiency between the medium flowing through the first heat exchange flow channel 710 and the second heat exchange flow channel 720 and the adsorbent is higher. In addition, the adjacent first heat exchange plate 731 and second heat exchange plate 741 are connected through the third heat exchange fin 761 therebetween, and the heat conduction path between the first heat exchange plate 731 and the second heat exchange plate 741 is shorter, so that the heat conduction efficiency between the first heat exchange assembly 730 and the second heat exchange assembly 740 is higher, the efficiency of heat exchange between the medium in the first heat exchange flow channel 710 and the adsorbate in the adsorption cavity 310 through the second heat exchange plate 741 is higher, and the efficiency of heat exchange between the medium in the second heat exchange flow channel 720 and the adsorbate in the adsorption cavity 310 through the first heat exchange plate 731 is higher.

Fig. 10 is a schematic view of another heat exchanger according to an embodiment of the present application, where the first heat exchange plate and the second heat exchange plate are adjacent to each other.
As shown in fig. 10, the surface of the heat exchanger 700 is attached with a first adsorbent 810.
In this way, the first adsorbent 810 attached to the surface of the heat exchanger 700 can adsorb and desorb the adsorbent in the adsorption cavity 310, so that the heat exchange efficiency between the adsorbent at the first adsorbent 810 and the heat exchanger 700 is high, and the adsorption and desorption efficiency of the adsorbent in the adsorption cavity 310 is high.
Illustratively, a surface of the first heat exchange assembly 730 and a surface of the second heat exchange assembly 740 are both attached with the first adsorbent 810. Specifically, the surface of each first heat exchange plate 731 and the surface of each second heat exchange plate 741 are attached with the first adsorbent 810.
When the heat exchanger 700 includes the heat conductive structure 760, the first adsorbent 810 is attached to the surface of the heat conductive structure 760. Specifically, when the heat conductive structure 760 includes third heat exchange fins 761, a surface of each third heat exchange fin 761 is attached with the first adsorbent 810.
Illustratively, the first adsorbent 810 may be adhered to the surface of the heat exchanger 700 by an adhesive such as epoxy.
In some possible embodiments, the first adsorbent 810 comprises activated carbon.
In some examples, the specific surface area of the activated carbon is in a range of greater than or equal to 200m 2/g and less than or equal to 5000m 2/g.
Thus, the adsorption and desorption performance of the activated carbon to the adsorbate is better.
Illustratively, the specific surface area of the activated carbon is in the range of greater than or equal to 800m 2/g and less than or equal to 2000m 2/g.
Thus, the adsorption quantity of the activated carbon to the adsorbate is large, and the stability of the adsorbate after being adsorbed by the activated carbon is good.
In some examples, the pore size of the activated carbon is in a range of greater than or equal to 0.1nm and less than or equal to 50 nm.
Thus, the adsorption and desorption performance of the activated carbon to the adsorbate is better.
Illustratively, the pore size of the activated carbon is in the range of greater than or equal to 0.5nm and less than or equal to 1.5 nm.
Thus, the adsorption quantity of the activated carbon to the adsorbate is large, and the stability of the adsorbate after being adsorbed by the activated carbon is good.
In some examples, the pore volume of the activated carbon is in a range of greater than or equal to 0.1cc/g and less than or equal to 5 cc/g.
Thus, the adsorption and desorption performance of the activated carbon to the adsorbate is better.
Illustratively, the pore volume of the activated carbon is in the range of greater than or equal to 0.3cc/g and less than or equal to 1.5 cc/g.
Thus, the adsorption quantity of the activated carbon to the adsorbate is large, and the stability of the adsorbate after being adsorbed by the activated carbon is good.
In some examples, the thickness of the first adsorbent 810 is in a range of greater than or equal to 0.1mm and less than or equal to 2 mm. Specifically, when the first adsorbent 810 includes activated carbon, the thickness of the activated carbon is in a range of greater than or equal to 0.1mm and less than or equal to 2 mm.
Thus, the thickness of the first adsorbent 810 is 0.1mm or more, and the adsorption amount of the first adsorbent 810 to the adsorbent can be made large. The first adsorbent 810 is less than or equal to 2mm, so that when adsorbing the adsorbent, the first adsorbent 810 close to the surface of the heat exchanger 700 cannot be fully adsorbed due to the fact that the stacking thickness of the first adsorbent 810 is thicker, when desorbing the adsorbent, the first adsorbent 810 is difficult to desorb due to the fact that the stacking thickness of the first adsorbent 810 is thicker, the first adsorbent 810 is far away from the first adsorbent 810 on the surface of the heat exchanger 700, and the efficiency of the first adsorbent 810 in adsorption and desorption is higher.
In some possible embodiments, the adsorption cavity 310 is filled with a second adsorbent 820.
Thus, the amount of the second adsorbent 820 that can be filled is large, and the adsorption amount of the adsorbent 300 to the adsorbent can be large.
In some examples, the surface of the heat exchanger 700 is attached with a first adsorbent 810 and the adsorption cavity 310 is filled with a second adsorbent 820.
Thus, the adsorber 300 has a large adsorption amount to the adsorbent and a high adsorption efficiency.
In other examples, the surface of the heat exchanger 700 is attached with the first adsorbent 810 and the adsorption cavity 310 is not filled with the second adsorbent 820.
In other examples, the adsorption cavity 310 is filled with the second adsorbent 820, and the first adsorbent 810 is not attached to the surface of the heat exchanger 700.
In some examples, the second adsorbent 820 is a granular structure.
In this way, the gaps between the second adsorbents 820 can be used to accommodate the adsorbed adsorbents, and the amount of adsorption of the adsorbents by the second adsorbents 820 can be made large.
By way of example, the second adsorbent 820 may include one or more of the following: silica gel, activated alumina, and the like.
In some examples, a second adsorbent 820 is packed between the first heat exchange assembly 730 and the second heat exchange assembly 740.
In this way, the adsorbate at the second adsorbent 820 can exchange heat with both the medium flowing through the first heat exchange flow channel 710 and the medium flowing through the second heat exchange flow channel 720, and the utilization efficiency of the second adsorbent 820 is high.
In some possible embodiments, the second adsorbent 820 is filled in the space 770 between the adjacent first heat exchange plates 731 and second heat exchange plates 741.
In this way, the first heat exchange plate 731, the second heat exchange plate 741 and the third heat exchange fin 761 can be used to exchange heat with the second adsorbent 820, and the second adsorbent 820 has high adsorption and desorption efficiency.
The space 770 between the adjacent first heat exchange plate 731 and second heat exchange plate 741 is partitioned into a plurality of subspaces by a plurality of third heat exchange fins 761 disposed therein, and each subspace is filled with the second adsorbent 820.
The heat exchanger 700 may be provided at edges of the first heat exchange plate 731 and the second heat exchange plate 741 with a porous plate having a plurality of through holes having a smaller diameter than the second adsorbent 820, the porous plate being for confining the second adsorbent 820 within the spacing space 770.
In this way, the second adsorbent 820 filled in the space 770 is not easily removed from the space 770, so that the efficiency of adsorption and desorption of the second adsorbent 820 is high. The through holes of the porous plate allow the adsorbent to flow through, and also allow the adsorbent to enter the space 770 to be adsorbed and the desorbed adsorbent to flow out of the space 770.

In this way, the size of each heat exchanger 700 may be made smaller, and the difficulty of manufacturing the heat exchangers 700 may be smaller. For example, when the first heat exchange assembly 730 includes the first heat exchange plate 731 and the second heat exchange assembly 740 includes the second heat exchange plate 741, the span of the first heat exchange plate 731 including the first in-plate heat exchange flow path and the second heat exchange plate 741 including the second in-plate heat exchange flow path can be made smaller, the requirements on the structural strength of the first heat exchange plate 731 and the second heat exchange plate 741 are lower, and the manufacturing of the first heat exchange plate 731 and the second heat exchange plate 741 is facilitated.
The third direction may be a vertical direction, a horizontal direction, or a direction inclined from the horizontal direction, for example.

The support plate 321 may be a porous plate, and the support plate 321 may serve to restrict the second adsorbent 820 in the space 770 from being withdrawn from the space 770.
