Description

Technical Field

[0001] This invention relates to the field of liquid cooling technology, and more specifically, to an adsorption refrigeration device, a liquid cooling system including the above-mentioned adsorption refrigeration device, and a temperature control method for the adsorption refrigeration system. Background Technology

[0002] The adsorption refrigeration device mainly involves three structural components: an adsorption bed, a condenser, and an evaporator. Multiple adsorption beds can be set up in parallel and / or in series. The specific connection method of the adsorption refrigeration device can refer to the current regenerative cycle, thermal wave cycle, and multi-stage cycle, etc.

[0003] Generally, during the adsorption stage, a heat source fluid is introduced into the adsorption bed to cause the adsorbent in the bed to desorb into a gaseous working fluid. The condenser is used to remove the desorbed gaseous working fluid from the adsorption bed and dissipate heat through the introduced cooling fluid, thus condensing it into a liquid working fluid. The adsorption process is generally considered complete when the adsorption bed has fully desorbed the gaseous working fluid.

[0004] Furthermore, a low-temperature cooling fluid can be introduced into the adsorption bed again to cool it down and allow it to enter the adsorption stage. At this time, the gaseous adsorbent in the chamber where the adsorbent is located is absorbed by the adsorbent, and the outlet of the evaporator's evaporation chamber is used to connect to the adsorption chamber of the adsorption bed so that the adsorbent in the evaporation chamber is continuously absorbed by the adsorbent. In this way, the evaporator can achieve evaporation and heat absorption.

[0005] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: the power of the heat source load that generates the heat source fluid changes during use, and once the power of the heat source load changes, the adsorption cooling effect will be poor. Therefore, the current adsorption cooling device has the problem of poor adaptability to heat source temperature. Summary of the Invention

[0006] In view of this, the first objective of the present invention is to provide an adsorption refrigeration device that can effectively solve the problem of instability during the adsorption stage of the adsorption refrigeration device, and the second objective of the present invention is to provide a liquid cooling system including the above-mentioned adsorption refrigeration device.

[0007] To achieve the first objective mentioned above, the present invention provides the following technical solution:

[0008] An adsorption refrigeration device, comprising:

[0009] An adsorption bed, wherein the adsorption chamber of the adsorption bed is provided with an adsorbent;

[0010] An evaporator, wherein the evaporation chamber of the evaporator is used to supply gaseous adsorbent to the adsorption chamber, and a refrigeration fluid channel is provided that can exchange heat with the liquid adsorbent in the evaporation chamber;

[0011] A chilled fluid supply port, connected to the outlet of the chilled fluid channel, is used to supply chilled fluid to the object being cooled for heat absorption from the object being cooled;

[0012] A chilled fluid return port is used to return the chilled fluid that has absorbed heat from the object being cooled, and is connected to the inlet of the chilled fluid channel;

[0013] The heat exchange device has a temperature control channel that is adjustable according to the heat exchange power, the outlet of the temperature control channel being connected to the inlet of the chilled fluid channel for supplying chilled fluid to the chilled fluid channel;

[0014] The first flow distribution device is used to distribute the fluid flowing out of the outlet of the chilled fluid channel to the chilled fluid supply port and the inlet of the temperature control channel according to a set distribution ratio, and the set distribution ratio is adjustable.

[0015] In the aforementioned adsorption refrigeration device, during use, a cooling heat exchange channel capable of absorbing heat from the object being cooled is connected in series between the chilled fluid supply port and the chilled fluid return port. In specific applications, since the cooling power of the object being cooled may change, if the flow rate from the chilled fluid outlet remains constant, the temperature at the chilled fluid return port will change. Therefore, the flow rate of the fluid flowing out of the chilled fluid supply port can be controlled by adjusting the distribution ratio of the first flow distribution device. The fluid flow rate can be adjusted according to the heating power of the object being cooled, ensuring a uniform temperature of the fluid returning from the chilled fluid return port. Excess fluid flowing out of the chilled fluid channel outlet enters the temperature control channel. The heat exchange power of the heat exchange device is then adjusted based on the fluid flow rate in the temperature control channel to ensure a uniform temperature of the fluid flowing out of the temperature control channel, which, together with the fluid returning from the chilled fluid return port, is supplied to the chilled fluid channel. In the aforementioned adsorption refrigeration device, when the heat output of the object being cooled fluctuates, the excess cooling capacity can be distributed through the first flow distribution device and the heat exchange device. Simultaneously, the flow rate and temperature returning to the refrigeration fluid channel remain constant, ensuring stable evaporation in the evaporator and thus guaranteeing a stable adsorption duration. This effectively avoids the problem of poor desorption results due to unstable adsorption duration. In summary, this adsorption refrigeration device effectively solves the problem of instability during the adsorption stage of adsorption refrigeration devices.

[0016] In some technical solutions, the heat exchange device includes a regulating device and a refrigeration heat exchanger. The refrigeration heat exchanger includes a refrigeration channel and a temperature control channel that can exchange heat with each other. The regulating device is connected in series with the refrigeration channel to adjust the fluid flow rate and / or temperature in the refrigeration channel, thereby adjusting the heat exchange power of the temperature control channel.

[0017] In some technical solutions, the regulating device is a drive pump or a flow valve.

[0018] In some technical solutions, the regulating device is a flow distribution valve, which includes a first temperature fluid inlet, a second temperature fluid inlet, and a combined outlet. The combined outlet is connected to the refrigeration channel. The first temperature fluid inlet and the second temperature fluid inlet are used to receive fluids at different temperatures. The flow distribution valve can adjust the flow ratio between the first temperature fluid inlet and the second temperature fluid inlet.

[0019] In some technical solutions, a cooling water storage tank and a chilled water storage tank are included, with the outlet of the refrigeration channel connected to the chilled water storage tank and the inlet connected to the outlet of the cooling water storage tank.

[0020] In some technical solutions, the outlet of the chilled water storage tank is equipped with a flow regulating valve, which is used to supply chilled water to the object being cooled; when the first flow distribution device is adjusted so that all the fluid flowing out of the chilled fluid channel outlet is distributed to the chilled fluid supply port, the flow regulating valve can adjust the chilled water outflow rate according to the fluid temperature at the chilled fluid return port.

[0021] Some technical solutions also include a compression refrigeration system, which includes a heat release channel for releasing heat from the refrigerant after throttling, and the heat release channel and the refrigeration fluid channel are connected in series.

[0022] Some technical solutions also include:

[0023] A heat source supply port is connected to the inlet of the heat exchange channel of the adsorption bed for supplying heat source fluid from the heat source load to the heat exchange channel. The compression refrigeration system also includes a heat receiving channel for absorbing heat from the refrigerant after compression by the compressor, and the outlet of the heat receiving channel is connected to the inlet of the heat exchange channel.

[0024] A heat source outlet is used to supply heat source fluid to the heat source load;

[0025] The second flow distribution device is used to distribute the fluid flowing out of the heat exchange channel to the heat source outlet and the inlet of the heated channel according to a set distribution ratio, and the set distribution ratio is adjustable.

[0026] In some technical solutions, a controller is also included. The controller can adjust the distribution ratio of the second flow distribution device based on the temperature of the fluid at the heat source supply port, thereby reducing the temperature difference between the fluid at the heat source supply port and a first preset temperature. The controller can also control the operating power of the compression refrigeration system based on the outlet fluid temperature of the heated channel, thereby reducing the temperature difference between the outlet temperature of the heated channel and the first preset temperature. Furthermore, the controller can adjust the distribution ratio of the first flow distribution device based on the temperature of the refrigerant return port fluid, thereby reducing the temperature difference between the refrigerant return port temperature and a second preset temperature. Finally, the controller can adjust the heat exchange power of the heat exchange device based on the temperature of the fluid at the outlet of the temperature control channel, thereby reducing the temperature difference between the outlet temperature of the temperature control channel and the second preset temperature.

[0027] In some technical solutions, the compression refrigeration system includes a compressor, a condensing heat exchanger, a throttling device, and an evaporating heat exchanger. The condensing heat exchanger includes a condensing-side refrigerant channel and a heating channel that exchange heat with each other. The evaporating heat exchanger includes an evaporating-side refrigerant channel and a heat-releasing channel that exchange heat with each other. The compressor, the condensing-side refrigerant channel, the throttling device, and the evaporating-side refrigerant channel are sequentially and cyclically connected.

[0028] Some technical solutions include a first cooling fluid interface and a second cooling fluid interface for the condenser;

[0029] Each heat exchange channel has a first end that is optionally connected to a first main interface via a first multi-way valve, and a second end that is optionally connected to a second main interface via a second multi-way valve, so that heating fluid can be optionally introduced into each heat exchange channel. The first main interface is connected to the heat source supply port and the outlet of the heated channel, and the second main interface is connected to the heat source discharge port and the inlet of the heated channel.

[0030] The evaporation chamber of the evaporator is optionally connected to the adsorption chambers corresponding to different adsorption beds in the plurality of adsorption beds through the first valve group. The evaporator is also provided with a refrigeration fluid channel for heat exchange with the liquid adsorption working fluid in the evaporation chamber.

[0031] The condenser's condensing chamber is optionally connected to the adsorption chambers corresponding to different adsorption beds in the plurality of adsorption beds through a second valve group. The condenser is also provided with a cooling fluid channel for exchanging heat with the gaseous adsorption working fluid in the condensing chamber.

[0032] The first end of each heat exchange channel is optionally connected to the first cooling fluid interface via a third multi-way valve, and the second end of each heat exchange channel is optionally connected to the second cooling fluid interface via a fourth multi-way valve, so that cooling fluid can be optionally introduced.

[0033] To achieve the second objective mentioned above, the present invention also provides a liquid cooling system comprising any of the aforementioned adsorption refrigeration devices, including a cooling object and a cooling heat exchange channel capable of exchanging heat with a heating element in the cooling object. One end of the cooling heat exchange channel is connected to the chilled fluid supply port of the adsorption refrigeration device, and the other end is connected to the chilled fluid return port of the adsorption refrigeration device. Since the aforementioned adsorption refrigeration device possesses the above-mentioned technical effects, an adsorption refrigeration device having this adsorption refrigeration device should also possess corresponding technical effects.

[0034] To achieve the third objective mentioned above, the present invention also provides a temperature control method for an adsorption refrigeration system. Specifically, this method includes dividing the refrigeration fluid prepared by the adsorption refrigeration system into a first portion of fluid supplied to the object being cooled and a second portion of fluid supplied to the temperature control channel of a heat exchange device according to a predetermined ratio; adjusting the predetermined ratio to adjust the flow rate of the first portion of fluid after it absorbs heat from the object being cooled and returns, so that the temperature of the returning first portion of fluid is within a preset temperature range; and adjusting the heat exchange power of the temperature control channel of the heat exchange device according to the temperature of the second portion of fluid after it absorbs heat from the temperature control channel of the heat exchange device, so that the temperature of the returning second portion of fluid is within the preset temperature range. Since this temperature control method, like one of the aforementioned methods of using the adsorption refrigeration device, adjusts the flow rate according to the cooling requirements of the object being cooled and adjusts the heat exchange power according to the flow rate of the heat exchange device to ensure that the final temperature of the returning refrigeration fluid is within a preset range, this adsorption refrigeration system temperature control method should also have corresponding technical effects.

[0042] This invention discloses an adsorption refrigeration device to effectively solve the problem of instability during the adsorption stage of the adsorption refrigeration device.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-2 , Figure 1 This is a schematic diagram of the adsorption refrigeration device provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of the liquid cooling system provided in an embodiment of the present invention.

[0045] In some embodiments, an adsorption refrigeration device is provided, which specifically includes an adsorption bed 1, a cryogenic fluid supply port 11, a cryogenic fluid return port 21, a compression refrigeration system, and a first flow distribution device 23.

[0046] The adsorption chamber of adsorption bed 1 is equipped with an adsorbent, and the working fluid used in conjunction with the adsorbent can flow through the adsorption chamber and the condensation chamber of condenser 7, as well as through evaporator 8. The working fluid and adsorbent are combined to form a working fluid pair. In an adsorption refrigeration system, multiple sets of working fluid pairs can be provided. One adsorbent can correspond to multiple working fluids, or multiple adsorbents can correspond to one working fluid.

[0047] For adsorption bed 1, there are two main working states: adsorption and desorption, which are generally carried out in stages. In the adsorption state, a low-temperature fluid is used to cool adsorption bed 1, allowing the adsorbent in adsorption bed 1 to adsorb the gaseous working medium, thus ensuring continuous adsorption capacity of the adsorption chamber until the adsorbent reaches a preset saturation state. Taking physical adsorption as an example, the gaseous working medium will liquefy into a liquid state, maintaining a low-pressure state within the adsorption chamber to continuously draw in gaseous working medium, such as continuously adsorbing the gaseous working medium from evaporator 8, allowing evaporator 8 to continuously evaporate and absorb heat. Of course, adsorption bed 1 can also obtain gaseous working medium from external sources instead of from evaporator 8. In the desorption state, a high-temperature fluid is generally used to heat the adsorption bed 1, causing the adsorbent in the adsorbent to desorb from the adsorbent and re-form a gaseous adsorbent. The gaseous adsorbent enters the condenser 7, where it is liquefied into a liquid adsorbent. Alternatively, the adsorbent can be discharged to the outside.

[0048] The adsorption bed 1 has a heat exchange channel 3 for heat exchange with the adsorbent in the adsorption chamber. This heat exchange channel 3 is a channel capable of carrying at least a high-temperature fluid (heat source fluid), so that a high-temperature fluid flows through it during the desorption phase of the adsorption bed 1. During the adsorption phase, the heat exchange channel 3 can be closed or used to carry a low-temperature fluid. The heat exchange channel 3 can exchange heat with the adsorbent, so that during the desorption phase, a high-temperature fluid flows through it, keeping the entire adsorption chamber at a high temperature. After absorbing heat, the adsorbent desorbs a gaseous adsorbent, which absorbs heat from the high-temperature fluid in the heat exchange channel 3. This gaseous adsorbent can be discharged to the outside or to the condensation chamber of the condenser 7, where it is condensed back into a gaseous adsorbent. It should be noted that a heat exchange channel 3 can be provided to alternately circulate high-temperature fluid and low-temperature fluid; or a heat exchange channel 3 can be provided specifically for low-temperature fluid, while another channel can be provided specifically for high-temperature fluid; or only a heat exchange channel 3 can be provided for either high-temperature or low-temperature fluid, and the adsorption or desorption stage of the adsorption bed 1 is not carried out through fluid, but through other heat-conducting structures, such as metal heat-conducting components, for heat dissipation.

[0049] Evaporator 8 refers to the evaporator 8 of the adsorption bed 1 system. The evaporation chamber of evaporator 8 supplies gaseous adsorbent to the adsorption chamber. It also includes a chilled fluid channel 28 for heat exchange with the liquid adsorbent in the evaporation chamber. The chilled fluid channel 28 can directly penetrate the evaporation chamber for direct heat exchange through the pipe wall, or it can utilize a heat exchange system. In operation, the chilled fluid introduced through the chilled fluid channel 28 transfers heat to the liquid adsorbent in the evaporation chamber. The liquid adsorbent evaporates into a gaseous state, carrying away the heat. The gaseous adsorbent enters the adsorption chamber, releases heat, and is absorbed by the adsorbent within the chamber. The released heat is then absorbed and dissipated through a heat transfer conductor or fluid.

[0050] A chilled fluid supply port 11 connects to the outlet of the chilled fluid channel 28 to supply chilled fluid to the cooling object 26 for heat absorption from the cooling object 26. The chilled fluid supply port 11 and the outlet of the chilled fluid channel 28 can be directly connected or indirectly connected. For example, if further cooling can be achieved through the compressor 17 refrigeration unit mentioned later, they can be indirectly connected through the heat release channel 202. A chilled fluid return port 21 is used to return the chilled fluid that has absorbed heat from the cooling object 26. In use, a cooling heat exchange channel is provided, which can be used to exchange heat with the cooling object 26 to primarily absorb heat from the cooling object 26. The cooling heat exchange channel can be integrated into the cooling object 26 or into the adsorption refrigeration unit; specific configuration can be determined as needed. The inlet end of the cooling heat exchange channel connects to the chilled fluid supply port 11, and the outlet end connects to the chilled fluid return port 21.

[0051] The heat exchange device 22 has a temperature control channel 221 with adjustable heat exchange power. By adjusting the heat exchange power, the outlet temperature of the temperature control channel 221 can be changed to avoid excessively high outlet temperatures. The heat exchange device 22 can be a cold storage device, in which case the temperature control channel 221 exchanges heat with the cold water of the cold storage device. The heat exchange power can be changed by adjusting the contact area or by adjusting the temperature of the cold water. Alternatively, it can be another heat-generating device that needs cooling, but whose heat output is adjustable. Of course, other heat exchange devices 22 can also be used, as long as the temperature of the temperature control channel 221 is adjustable.

[0052] The temperature control channel 221 is connected to the inlet of the chilled fluid channel 28 to supply chilled fluid to the chilled fluid channel 28. That is, the outlet of the temperature control channel 221 can supply fluid to the chilled fluid channel 28. It should be noted that the chilled fluid return port 21 also needs to supply fluid to the chilled fluid channel 28. At this time, the fluid returning from the chilled fluid return port 21 and the fluid flowing out of the temperature control channel 221 merge together to flow into the chilled fluid channel 28, so as to ensure the amount of fluid in the chilled fluid channel 28.

[0053] The first flow distribution device 23 is used to distribute the fluid flowing out of the outlet of the chilled fluid channel 28 to the chilled fluid supply port 11 and the inlet of the temperature control channel 221 according to a set distribution ratio, and the set distribution ratio is adjustable. That is, part of the fluid cooled by the chilled fluid channel 28 is supplied to the chilled fluid supply port 11 to cool the object 26, and the other part is supplied to the temperature control channel 221 to cool other equipment or cold storage equipment through the heat exchange device 22.

[0054] The first flow distribution device 23 may include a flow distribution valve used in conjunction with a drive pump. The drive pump may be located at the inlet of the flow distribution valve to drive fluid flow. The inlet of the flow distribution valve is connected to the outlet of the chilled fluid channel 28, and the two outlets of the flow distribution valve are respectively connected to the chilled fluid supply port 11 and the inlet of the temperature control channel 221. The internal valve core is movable, allowing fluid to enter the inlet and changing the proportion to enter the two outlets respectively. Of course, the first flow distribution device 23 may include two double-connector flow valves to regulate the flow of the two branches respectively. Other first flow distribution devices 23 may also be used.

[0055] In the aforementioned adsorption refrigeration device, during use, a cooling heat exchange channel capable of absorbing heat from the cooled object 26 is connected in series between the chilled fluid supply port 11 and the chilled fluid return port 21. In specific applications, since the cooling power of the cooled object 26 may change, if the flow rate from the chilled fluid outlet remains constant, the temperature of the chilled fluid return port 21 will change. Therefore, the flow rate of the fluid flowing out of the chilled fluid supply port 11 can be controlled by adjusting the distribution ratio of the first flow distribution device 23. The flow rate can be adjusted according to the heating power of the cooled object 26 to ensure a uniform temperature of the fluid returning to the chilled fluid return port 21. Excess fluid flowing out of the chilled fluid channel 28 enters the temperature control channel 221. The heat exchange power of the heat exchange device 22 is adjusted based on the fluid flow rate in the temperature control channel 221 to ensure a uniform temperature of the fluid flowing out of the temperature control channel 221, which, together with the fluid returning from the chilled fluid return port 21, is supplied to the chilled fluid channel 28. In the aforementioned adsorption refrigeration device, when the heating power of the object being cooled 26 fluctuates, the excess cooling capacity can be distributed through the first flow distribution device 23 and the heat exchange device 22. Simultaneously, the flow rate and temperature returning to the refrigeration fluid channel 28 remain constant, ensuring stable evaporation in the evaporator 8. This, in turn, guarantees a stable adsorption duration and effectively avoids the problem of poor desorption results due to unstable adsorption duration. In summary, this adsorption refrigeration device effectively solves the problem of instability during the adsorption stage of adsorption refrigeration devices.

[0056] In some embodiments, the heat exchange device 22 may specifically include a regulating device 222 and a refrigeration heat exchanger 223. The refrigeration heat exchanger 223 includes a refrigeration channel 224 and a temperature control channel 221 capable of exchanging heat with each other. The refrigeration channel 224 is used to obtain cooling energy from the temperature control channel 221, which can be used to cool other cooling devices or store cold. The regulating device 222 is connected in series with the refrigeration channel 224 to adjust the fluid flow rate and / or temperature in the refrigeration channel 224, thereby adjusting the heat exchange power of the temperature control channel 221.

[0057] Specifically, the regulating device 222 can be a drive pump with adjustable speed to drive the fluid flow in the refrigeration channel 224. The drive pump can adjust its speed to regulate the fluid flow rate in the refrigeration channel 224. A faster fluid flow rate results in higher heat exchange efficiency. However, to ensure temperature control, the heat exchange path between the refrigeration channel 224 and the temperature control channel 221 must be fully guaranteed to ensure sufficient heat exchange even with increased fluid flow rate. Alternatively, the regulating device 222 can also be a flow valve to directly adjust the flow rate.

[0058] The regulating device 222 can also be a temperature switching valve to introduce different fluids and achieve different temperatures. Sometimes, the regulating device 222 can also be a flow regulating valve; changes in flow rate will also change the temperature. Generally, higher temperatures result in greater heat exchange power, which in turn affects the fluid temperature in the temperature control channel 221.

[0059] For the refrigeration heat exchanger 223, it is essential to ensure that the heat exchange path is long enough to avoid insufficient heat exchange when adjusting the heat exchange power. Simultaneously, the refrigeration channel 224 and the temperature control channel 221 can be arranged in counter-current flow to ensure that the outlet temperature of the refrigeration channel 224 is close to the inlet temperature of the temperature control channel 221, thereby achieving sufficient heat exchange. The inlet temperature of the refrigeration channel 224 and the outlet temperature of the temperature control channel 221 can be very close, or the inlet temperature of the refrigeration channel 224 can be significantly higher than the outlet temperature of the temperature control channel 221; the specific settings can be adjusted according to requirements.

[0060] The above changes are mainly achieved by adjusting the heat flux through the regulating device 222 to ensure the change in heat exchange efficiency.

[0061] During use, when the heating power of the object being cooled 26 changes, the first flow distribution device 23 will automatically adjust the distribution ratio, thus changing the fluid flow rate entering the temperature control channel 221. At this time, the flow rate, temperature, and / or flow rate of the cooling channel 224 are changed by the adjusting device 222, so that the outlet temperature of the temperature control channel 221 reaches the preset temperature.

[0062] In some embodiments, the regulating device 222 can also be a flow distribution valve, which includes a first temperature fluid inlet, a second temperature fluid inlet, and a combined outlet. The combined outlet is connected to the refrigeration channel 224, and the first and second temperature fluid inlets are used to receive fluids at different temperatures. The flow distribution valve can adjust the flow ratio of the first and second temperature fluid inlets to change the fluid temperature at the combined outlet. In practical applications, the first temperature fluid inlet can be connected to the return water of another cooling device, and the second temperature fluid inlet can be connected to the outlet of the cooling water storage tank 24.

[0063] In some embodiments, the adsorption refrigeration device may further include a cooling water storage tank 24 and a chilled water storage tank 25, wherein the outlet of the refrigeration channel 224 is connected to the chilled water storage tank 25 and the inlet is connected to the outlet of the cooling water storage tank 24, so that the outlet of the cooling water storage tank 24 can be prepared into cold water through the refrigeration channel 224 and then introduced into the chilled water storage tank 25 for storage and use.

[0064] In some embodiments, the outlet of the chilled water storage tank 25 may be equipped with a flow regulating valve for supplying chilled water to the cooling object 26, so that not only the chilled fluid supply port 11 can supply cooling capacity to the cooling object 26, but also the cooling capacity can be supplied to the cooling object 26 through the chilled water storage tank 25. The outlet of the chilled water storage tank 25 can be connected to the cooling heat exchange channel; to avoid affecting the use of the evaporator 8, it is preferable that the cooling object 26 is provided with a dedicated cooling fluid channel, which exchanges heat with the cooling heat exchange channel through a heat exchanger. The water outlet of the chilled water storage tank 25 can also exchange heat with the cooling fluid channel through another heat exchanger. The water outlet after heat exchange can flow back into the refrigeration channel 224 or return to the cooling water storage tank 24. Specifically, the configuration can be adjusted as needed.

[0065] In use, when the first flow distribution device 23 is adjusted so that all the fluid flowing out of the chilled fluid channel 28 is distributed to the chilled fluid supply port 11, it indicates that the cooling capacity in the chilled fluid channel 28 is no longer sufficient to meet the requirements of the object being cooled 26. At this time, the flow regulating valve can be adjusted according to the fluid temperature at the chilled fluid return port 21 to ensure that the temperature at the chilled fluid return port 21 meets the requirements.

[0066] In some embodiments, when a cooling water storage tank 24 is provided, the cooling water storage tank 24 can be a dry cooling water storage tank or a wet cooling water storage tank.

[0067] In some embodiments, the cooling capacity of the evaporator 8 is affected by the heating power of the heat source load 29, and during use, the heating power of the heat source load 29 and the heating power of the object being cooled 26 are not completely synchronized. Furthermore, the cooling power transferred from the heating power of the heat source load 29 to the adsorption bed 1 may not necessarily meet the cooling power requirements of the object being cooled 26. Therefore, a compression refrigeration system is generally provided for supplemental cooling. A compression refrigeration system refers to a system capable of compression refrigeration. A compression refrigeration system mainly includes a compressor 17, a condenser, a throttling device 19, and an evaporator. The compressor 17 is used to compress the refrigerant to form a high-temperature refrigerant. The high-temperature refrigerant is cooled at the condenser to exchange heat. The cooled refrigerant enters the throttling device 19, and after being throttled by the throttling device 19, it is further cooled and enters the evaporator to absorb heat through the evaporator, and then returns to the compressor 17.

[0068] Specifically, the compression refrigeration system may include a heat release channel for releasing heat from the throttled refrigerant, such as a heat release channel that can obtain cooling capacity from the evaporator. The heat release channel 202 and the refrigerant fluid channel 28 are connected in series, either before or after the distribution port of the first flow distribution device 23. Preferably, the inlet of the heat release channel 202 is connected to the outlet of the refrigerant fluid channel 28, and the first flow distribution device 23 distributes the fluid flowing out of the outlet of the heat release channel 202 to the refrigerant supply port 11 and the inlet of the temperature control channel 221 according to a set distribution ratio.

[0069] In some embodiments, the heat energy generated by the compression refrigeration system can be further utilized to supply the adsorption bed 1. For ease of explanation, a heat source supply port 2, a heat source discharge port 5, and a second flow distribution device 30 may also be included.

[0070] The heat source supply port 2 is used to supply heat source fluid from the heat source load 29 to the heat exchange channel 3 of the adsorption bed 1, and the heat source discharge port 5 is used to supply heat source fluid to the heat source load 29. In use, the heat source supply port 2 is connected to the heat source channel of the heat source load 29, and the heat source discharge port 5 is connected to the aforementioned heat source channel. The fluid flowing out from the heat source discharge port 5 enters the heat source channel, obtains heat from the heating element of the heat source load 29 at the heat source channel to raise the temperature, and then discharges into the heat source supply port 2.

[0071] The compression refrigeration system also includes a heating channel 182, which is used to absorb heat from the refrigerant after compression by the compressor 17. The heating channel 182 is used to allow the fluid to absorb heat after compression by the compressor 17, thereby raising the internal temperature of the fluid. The heating channel 182 can be located outside the compressor 17 casing. The heated refrigerant will transfer heat to the compressor 17 casing. Alternatively, the heating channel 182 can also obtain heat from the condenser of the compression refrigeration system. The high-temperature refrigerant after compression will enter the condenser, and the heating channel 182 can directly exchange heat with the refrigerant condensation channel in the condenser 7, or it can achieve indirect heat exchange through a heat exchanger.

[0072] The outlet of the heating channel 182 is connected to the inlet of the heat exchange channel 3 to supply high-temperature fluid to the heat exchange channel 3. Both the outlet of the heating channel 182 and the heat source supply port 2 supply heat exchange fluid to the heat exchange channel 3. Specifically, the heat source fluid entering through the inlet of the heating channel 182 absorbs heat from the refrigerant compressed by the compressor 17 at the heating channel 182, and after being heated, it is supplied again to the inlet of the heat exchange channel 3 for desorption in the adsorption bed 1.

[0073] The second flow distribution device 30 is used to distribute the fluid flowing out of the outlet of the heat exchange channel 3 to the heat source outlet 5 and the inlet of the heated channel 182 according to a set distribution ratio. The set distribution ratio is adjustable; that is, the proportion of fluid flowing out of the outlet of the heat exchange channel 3 to the heat source outlet 5 and the inlet of the heated channel 182 can be adjusted through the adjustment function of the flow distribution device. The second flow distribution device 30 can be a flow distribution valve. The inlet of the flow distribution valve is connected to the outlet of the heat exchange channel 3, and the two outlets of the flow distribution valve are respectively connected to the heat source outlet 5 and the inlet of the heated channel 182. The internal valve core is movable, allowing fluid to enter the inlet and changing the ratio to enter the two outlets respectively. Alternatively, the second flow distribution device 30 can include two double-connector flow valves to adjust the flow of the two branches respectively. Other flow distribution devices can also be used. The first flow distribution device 23 and the second flow distribution device 30 can also be based on existing technology.

[0074] In operation, the heat source channel of the heat source load 29 is connected between the heat source supply port 2 and the heat source discharge port 5. After the heat source load 29 starts working, the fluid in the heat source channel is circulated. The fluid is heated by the heating device of the heat source load 29 through the heat source channel and then flows to the heat source supply port 2, and then to the heat exchange channel 3 of the adsorption bed 1. At this time, the adsorption bed 1 is in the desorption stage, and the fluid in the heat exchange channel 3 will cool down and then be discharged from the outlet of the heat exchange channel 3. It can then be discharged into the heat source discharge port 5 to enter the heat source channel again, acquire heat again, and return to the adsorption bed 1 from the heat source supply port 2 for heat release. At this time, the heat generation power of the heat source load 29 can be monitored. When the heat generation power increases or decreases, the flow rate of the fluid entering the heat source channel can be adjusted by the first flow distribution device 23 to ensure that the fluid temperature at the heat source supply port 2 reaches the preset temperature, which is the optimal desorption temperature of the adsorption bed 1. The other portion of the fluid enters the heating channel 182. The compression and refrigeration power of the compression and refrigeration system can be adjusted according to the fluid flow rate in the heating channel 182, thereby changing the heat release power to ensure that the outlet temperature of the heating channel 182 reaches the preset temperature. Through this adjustment method, even if the power of the heat source load 29 changes, the final fluid flow rate entering the heat exchange channel 3 remains unchanged, and the temperature remains stable, ensuring stability in the desorption stage and facilitating stable alternating desorption and adsorption in the adsorption bed 1. Furthermore, this method fully utilizes the thermal power of the heat source load 29, resulting in better heat recovery.

[0075] In some embodiments, for better automatic adjustment, a controller can be provided. The controller controls the first flow distribution device 23 to adjust the flow distribution based on the temperature of the heat source supply port 2, so that the temperature of the heat source supply port 2 reaches a preset temperature. Then, based on the temperature or flow rate of the outlet of the heated channel 182, the operating power of the compression refrigeration system is adjusted so that the temperature of the outlet of the heated channel 182 also reaches the preset temperature. At this time, the temperature and flow rate of the high-temperature fluid entering the adsorption bed 1 for heat exchange do not change and can adapt to changes according to the load. Of course, when obtaining the outlet temperature of the heated channel 182 and the temperature of the heat source supply port 2, mutual interference should be avoided. It should be noted that for the heat source load 29, controlling the temperature of the heat source supply port 2 can effectively control the heat dissipation temperature of the heat source load 29, preventing the heat source load 29 from not being effectively cooled.

[0076] Specifically, the controller can adjust the flow distribution ratio based on the temperature of the heat source supply port 2, thereby reducing the temperature difference between the heat source supply port 2 and the first preset temperature. This control method can be PID-regulated, and the smaller the temperature difference between the heat source supply port 2 and the first preset temperature, the better. Specifically, if the temperature of the heat source supply port 2 is higher than the first preset temperature, the second flow distribution device 30 adjusts the flow rate, increasing the fluid flow rate at the heat source outlet 5. This increase in flow rate in the heat source channel lowers the outlet water temperature, and consequently reduces the flow rate in the heating channel 182. Conversely, if the temperature of the heat source supply port 2 is lower than the first preset temperature, the second flow distribution device 30 adjusts the flow rate, decreasing the flow rate at the heat source outlet 5. This decrease in flow rate in the heat source channel raises the outlet water temperature, and consequently increases the flow rate in the heating channel 182. This repeated adjustment gradually reduces the temperature difference between the heat source supply port 2 and the first preset temperature. The first preset temperature is preferably an acceptable desorption temperature for the adsorption bed 1. In order to improve the desorption effect, the first preset temperature is preferably the optimal temperature of the adsorption bed 1 to ensure that the adsorption bed 1 can present the best desorption effect.

[0077] The controller can control the operating power of the compression refrigeration system based on the outlet temperature of the heated channel 182, so as to reduce the temperature difference between the outlet temperature of the heated channel 182 and the first preset temperature. The control method can be PID regulation, and the smaller the temperature difference between the heat source supply port 2 and the first preset temperature, the better. Specifically, based on the above adjustments: when the fluid flow in the heated channel 182 decreases, the outlet temperature of the heated channel 182 is higher than the first preset temperature. Therefore, the refrigeration power of the compression refrigeration system needs to be reduced. A decrease in refrigeration power reduces the heat power at the corresponding hot end (compressor 17 and condenser 18), resulting in a decrease in the outlet temperature of the corresponding heated channel 182. Conversely, when the fluid flow rate in the heated channel 182 increases, the outlet temperature of the heated channel 182 is lower than the first preset temperature. Therefore, the refrigeration power of the compression refrigeration system needs to be increased. An increase in refrigeration power raises the temperature at the corresponding hot end (compressor 17 and condenser 18), resulting in an increase in the outlet temperature of the corresponding heated channel 182.

[0078] In some embodiments, similarly, for better flow regulation, the controller can also adjust the distribution ratio of the first flow distribution device 23 based on the heating power of the cooling object 26, so that the temperature of the return port of the refrigerant reaches a preset temperature, thereby ensuring the cooling effect of the evaporator 8. And according to the distribution result of the second flow distribution device 30, the heat exchange device 22 is controlled to adjust the heat exchange power so that excess cold energy can be exchanged out, ensuring that when the remaining fluid is supplied to the refrigerant channel 28, the temperature reaches a preset temperature, thereby ensuring the cooling effect of the evaporator 8.

[0079] Specifically, the controller can adjust the distribution ratio of the first flow distribution device 23 based on the temperature of the chilled fluid return port 21, so as to reduce the temperature difference between the chilled fluid return port 21 and the second preset temperature. The control method can be PID regulation, and the smaller the temperature difference between the chilled fluid return port 21 and the second preset temperature, the better. Specifically, if the fluid temperature at the chilled fluid return port 21 is higher than the second preset temperature, the first flow distribution device 23 adjusts the flow rate at the chilled fluid return port 21, thereby increasing the fluid flow rate at the chilled fluid supply port 11. After the fluid flow rate at the chilled fluid supply port 11 increases, the outlet water temperature of the corresponding cooling heat exchange channel decreases, and the fluid flow rate in the temperature control channel 221 decreases. Conversely, if the temperature at the chilled fluid return port 21 is lower than the first preset temperature, the first flow distribution device 23 adjusts the flow rate at the chilled fluid supply port 11, thereby decreasing the fluid flow rate in the heat source channel. After the fluid flow rate in the heat source channel decreases, the outlet water temperature of the corresponding cooling heat exchange channel increases, and the fluid flow rate in the temperature control channel 221 increases. By repeatedly adjusting in this way, the temperature difference between the refrigerant return port 21 and the second preset temperature can be reduced. The second preset temperature is preferably an evaporation temperature that the evaporator 8 can accept, and in order to improve the evaporation effect, the second preset temperature is preferably the optimal temperature of the evaporator 8 to ensure that the adsorption bed 1 can present the best evaporation effect.

[0080] The controller can adjust the heat exchange power of the heat exchange device 22 based on the temperature of the fluid at the outlet of the temperature control channel 221, so as to reduce the temperature difference between the outlet temperature of the temperature control channel 221 and the second preset temperature. The control method can be PID regulation, and the smaller the temperature difference between the outlet temperature of the temperature control channel 221 and the second preset temperature, the better. Specifically, after the above adjustment: when the fluid flow rate in the temperature control channel 221 decreases, the outlet temperature of the temperature control channel 221 is higher than the second preset temperature, so the heat exchange power of the heat exchange device 22 is reduced, and the outlet temperature of the corresponding temperature control channel 221 will decrease; when the fluid flow rate in the temperature control channel 221 increases, the outlet temperature of the temperature control channel 221 is lower than the second preset temperature, so the heat exchange power of the heat exchange device 22 is increased, and the outlet temperature of the corresponding temperature control channel 221 will increase.

[0081] In some embodiments, the adsorption time can be controlled by adjusting the temperature and flow rate of the refrigerant return port 21 of the evaporator 8, so that the final adsorption time and desorption time reach a stable ratio, especially in multi-bed systems where desorption and adsorption can be closely alternated.

[0082] When in use, the refrigerant, after being compressed by compressor 17, forms a hot fluid. This hot fluid exchanges heat with the heated channel 182 in the condensing-side refrigerant channel 181, thus raising the temperature of the fluid in the heated channel 182. Generally, the temperature of the compressed hot fluid needs to be higher than the set heating fluid temperature of the adsorbent in the adsorption bed 1 to ensure that the heated channel 182 is effectively heated to meet the requirements of the adsorption bed 1. After releasing heat, the refrigerant in the refrigerant channel cools down. The cooled fluid is then throttled by the throttling device 19 to form a low-temperature fluid. This low-temperature fluid enters the evaporating-side refrigerant channel 201, where it absorbs heat from the heat release channel to achieve a temperature increase. After flowing out of the evaporating-side refrigerant channel 201, the refrigerant can re-enter compressor 17, be compressed by compressor 17, and then supplied to the condensing-side refrigerant channel 181. This cycle repeats continuously, and during the cycle, the refrigerant may undergo a gas-liquid phase transition. It should be noted that if the refrigerant temperature at the inlet of the throttling device 19 is too high, a portion of the refrigerant can be discharged from the throttling outlet to cool the inlet refrigerant and meet the throttling requirements. From a temperature perspective, to better meet usage requirements, the inlet temperatures of the condensing-side refrigerant channel 181, the heat exchange channel 3, and the heating channel 182 can be sequentially decreased; while the inlet temperatures of the evaporating-side refrigerant channel 201, the outlet temperatures of the evaporating-side refrigerant channel 201, the chilled fluid supply port 11, and the heat release channel inlet temperatures can be sequentially increased.

[0083] By using the above method, the number of heat exchange stages can be reduced, thereby improving heat transfer efficiency.

[0084] In some embodiments, the system generally includes a condenser 7, in which the adsorbent flows through the condensation chamber of the condenser 7, the evaporation chamber of the evaporator 8, and the adsorption chamber of the adsorption bed 1 to form an adsorption refrigeration system.

[0085] Specifically, the evaporation chamber of the evaporator 8 can be selectively connected to the adsorption chambers corresponding to different adsorption beds 1 in multiple adsorption beds 1 through the first valve group 9. The evaporator 8 is also provided with a refrigeration fluid channel 28 for heat exchange with the liquid adsorption working fluid in the evaporation chamber.

[0086] The condensing chamber of the condenser 7 is optionally connected to the adsorption chambers of different adsorption beds 1 in the plurality of adsorption beds 1 through the second valve group 10. The condenser 7 is also provided with a cooling channel 16 for heat exchange with the gaseous adsorption working fluid in the condensing chamber.

[0087] Generally, to achieve continuous refrigeration, multiple adsorption beds 1 are connected in parallel, with at least some adsorption beds 1 having staggered desorption and adsorption time periods. For a specific adsorption bed 1, when entering the adsorption stage, it needs to be connected to the evaporation chamber through the first valve group 9 and disconnected from the condensation chamber through the second valve group 10; conversely, when entering the desorption stage, it needs to be disconnected from the evaporation chamber through the first valve group 9 and connected to the condensation chamber through the second valve group 10. The first valve group 9 and the second valve group 10 can be reversing valves, multi-way valves, or valve groups formed by combining multiple on / off valves. Alternatively, the first valve group 9 and the second valve group 10 can be combined into a single reversing valve.

[0088] The condenser 7's condensing chamber receives the gaseous adsorbent discharged from the adsorption chamber of the adsorption bed 1. When the heat source fluid enters the adsorption bed 1, it decomposes into a gaseous adsorbent, which then enters the condensing chamber and releases heat. This heat is released into the cooling channel 16 of the condenser 7 and carried out by the fluid in the cooling channel 16. After releasing heat, the gaseous adsorbent forms a liquid adsorbent, thus continuously receiving the gaseous adsorbent discharged from the adsorption chamber.

[0089] In some embodiments, the first end of each heat exchange channel 3 is optionally connected to a first main interface via a first multi-way valve 12, and the second end of each heat exchange channel 3 is optionally connected to a second main interface via a second multi-way valve 13, so that heating fluid can be optionally introduced. The first main interface is connected to the heat source supply port and the outlet of the heated channel 182; the second main interface is connected to the heat source discharge port and the inlet of the heated channel 182.

[0090] Each heat exchange channel 3 has its first end connected to each outlet of the first multi-way valve 12, and its inlet connected to the first main interface. The inlet of the first multi-way valve 12 can optionally be connected to any one of the outlets. Similarly, each heat exchange channel 3 has its second end connected to each inlet of the second multi-way valve 13, and its outlet connected to the second main interface. The outlet of the second multi-way valve 13 can optionally be connected to any one of the inlets.

[0091] In some embodiments, a first cooling fluid interface 4 and a second cooling fluid interface 6 may be further provided. Specifically, the first end of each heat exchange channel 3 may be optionally connected to the first cooling fluid interface 4 via a third multi-way valve 14, and the second end of each heat exchange channel 3 may be optionally connected to the second cooling fluid interface 6 via a fourth multi-way valve 15, so that cooling fluid can be optionally introduced. At this time, the cooling fluid used to cool the adsorbent in the adsorption stage and the heating fluid used to heat the adsorbent in the desorption stage can share the heat exchange channel 3, so that the heating fluid (heat source fluid) and cooling fluid alternately flow into the heat exchange channel 3.

[0092] The first cooling fluid interface 4 serves as the cooling fluid supply port, and the second cooling fluid interface 6 serves as the cooling fluid discharge port. The first end of each heat exchange channel 3 is connected to each outlet of the third multi-way valve 14, while the inlet of the third multi-way valve 14 is connected to the first cooling fluid interface 4, and the inlet of the third multi-way valve 14 can optionally be connected to any one of the outlets. The second end of each heat exchange channel 3 is connected to each inlet of the fourth multi-way valve 15, while the outlet of the fourth multi-way valve 15 is connected to the second cooling fluid interface 6, and the outlet of the fourth multi-way valve 15 can optionally be connected to any one of the inlets.

[0093] This allows the heat exchange channel 3 to be circulated with high-temperature fluid during the desorption phase, i.e., connected between the first main interface and the second main interface, and with low-temperature fluid during the adsorption phase, i.e., connected between the first cooling fluid interface 4 and the second cooling fluid interface 6.

[0094] For ease of control, the first valve group 9, the second valve group 10, the inlet three-way valve, the first multi-way valve 12, the second multi-way valve 13, the third multi-way valve 14, the fourth multi-way valve 15, and the switching valve are all electrically controlled valves, which are all connected to the controller and can be controlled by the controller; moreover, the control port of the electric heating device and the control port of the drive pump are also connected to the controller and can be controlled by the controller.

[0095] In some embodiments, unless otherwise stated or contradicted, the adsorption refrigeration system comprises an adsorption working fluid circulation system consisting of an adsorption bed 1, a condenser 7, and an evaporator 8, which may specifically constitute a multi-stage circulation system, a return circulation system, a heat wave circulation system, or other circulation systems.

[0096] Based on the adsorption refrigeration device provided in the above embodiments, the present invention also provides a liquid cooling system. This liquid cooling system includes any one of the adsorption refrigeration devices described in the above embodiments, comprising a cooling object 26 and a cooling heat exchange channel capable of exchanging heat with the heating device in the cooling object 26. Since this liquid cooling system uses the adsorption refrigeration device described in the above embodiments, the beneficial effects of this liquid cooling system are explained in the above embodiments.

[0097] Based on the adsorption refrigeration device provided in the above embodiments, the present invention also provides a temperature control method for an adsorption refrigeration system, which mainly includes the following steps:

[0098] Step S100: The cryogenic fluid prepared by the adsorption refrigeration system is divided into a first portion of fluid for the object to be cooled and a second portion of fluid for the temperature control channel of the heat exchange device according to a set ratio.

[0099] The distribution can be done manually or by referring to and using the first flow distribution device described above. The preparation method of the cryogenic fluid produced by the adsorption refrigeration system can also refer to the above embodiments. It can be that the fluid at the outlet of the cryogenic fluid channel of the evaporator of the adsorption refrigeration system is distributed according to the aforementioned set ratio.

[0100] Step S200: Adjust the set ratio according to the temperature of the first portion of fluid after absorbing heat from the cooling object and returning to the source to adjust the flow rate of the first portion of fluid so that the temperature of the first portion of fluid returning to the source is within a preset temperature range.

[0101] The first portion of fluid supplied to the object being cooled, after absorbing heat directly or indirectly from that object, needs to flow back into the cooling fluid channel of the evaporator; hence, it is called the first portion of fluid returning. When there are multiple objects being cooled, this first portion of fluid can be redistributed. The heat absorbed by the first portion of fluid from the object being cooled is affected by the heating power of that object, which in turn is influenced by its own function or its own needs.

[0102] When the heat output of the object being cooled changes, the temperature of the first portion of the fluid can be stabilized within a stable temperature range by adjusting the flow rate of the first portion of fluid. This is similar to the preset temperature range mentioned above. Generally, the temperature difference within the preset temperature range should not exceed 1 degree Celsius. The preset temperature range can be between Ty and 1.05Ty, where Ty is a preset value, typically determined by the evaporator settings of the adsorption refrigeration system. Specifically, the preset temperature range can be between Ty and 1.03Ty. Ty is generally not higher than the current ambient temperature and is generally lower than the lowest fluid temperature that the natural cooling device can provide in the current environment.

[0103] Step S300: Adjust the heat exchange power of the heat exchange device temperature control channel according to the temperature of the second portion of fluid after absorbing heat from the temperature control channel and returning, so that the temperature of the second portion of fluid returning is within the preset temperature range.

[0104] The arrangement of the heat exchange device can refer to some of the above embodiments. Since the flow rate of the second fluid entering is adjusted according to the change in the heat generation power of the object being cooled, the flow rate cannot be adjusted. However, a heat exchange device capable of adjusting the heat exchange power can be set up so that the temperature of the second fluid returning can be stabilized within a preset temperature range, which is consistent with the preset temperature range mentioned above.

[0105] Then, the first and second portions of the refluxed fluid are supplied together to the refrigerant fluid channel of the evaporator, so that the evaporator can obtain refluxed fluid with stable temperature and flow rate, which is conducive to the orderly operation of the entire adsorption refrigeration system.

[0106] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0107] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
