The heat exchange module 10 includes a first circulation pipe 100 , and a part of the first circulation pipe 100 passes through the cabinet to take away heat in the cabinet. Wherein, the first fluid L1 is stored in the first circulation pipe 100 . In this application, the term "rack" refers to a carrier device in which servers are disposed. For example, the cabinet may be a server carrying device located in a computer room, and the server may include but not limited to components such as a central processing unit, a graphics processing unit, a hard disk, a power supply, and a memory. However, the present application is not limited to the installation location of the cabinet. By passing a part of the first circulation pipe 100 in the cabinet, the first fluid L1 flowing along the first circulation pipe 100 can effectively take away the heat in the cabinet, so that the cabinet maintains a stable working temperature. It is worth mentioning that the above "through" means that a part of the first circulation pipe 100 is located in the cabinet, and the first circulation pipe 100 located in the cabinet can also be connected or connected in series with large-area heat dissipation blocks, heat dissipation plates, and heat dissipation fins to increase the rate of heat exchange.

In some embodiments, the first fluid L1 may be water, aqueous glycol solution or a compatible coolant. Preferably, the first fluid L1 may be ionized water. More preferably, the first fluid L1 is deionized water added with anti-corrosion inhibitors and bactericides, so as to reduce corrosion, fouling and microbial growth of pipelines, thereby reducing heat dissipation and reliability. Still more preferably, the first fluid L1 is deionized water that can satisfy the following conditions:

In some embodiments, the temperature of the first fluid L1 ranges from 10°C to 45°C, which needs to be higher than the ambient dew point.

In some embodiments, the driving module 11 includes a driving pump 110 , and the driving pump 110 is disposed in the first circulation pipe 100 and drives the first fluid L1 in the first circulation pipe 100 . For example, the driving pump 110 may be a plunger pump in a pressure test pump, which uses a relief valve to control pressure and a throttle valve to control flow. However, the present application is not limited thereto, and all pumps known to those skilled in the art can be applied in the present application. For example, the driving pump 110 may also be a metering pump, or other suitable pumps.

In some embodiments, there are a plurality of driving pumps 110, at least one of the plurality of driving pumps 110 is in an operating state, and at least one of the plurality of driving pumps 110 is in an off state.

A circulation pipe 100. When one of the two driving pumps 110 is in the operating state, the other of the two driving pumps 110 is in the off state. In this way, the entire driving module 11 only relies on one driving pump 110 to drive the delivery of the first fluid L1, while the other driving pump 110 is used for backup. In this case, the two drive pumps 110 can be turned off in a fixed period in turn to increase the lifetime of the device. In addition, through the alternate activation design, the driving module 11 can not affect the operation of the heat exchange system 1 during maintenance/maintenance.

The buffer module 12 is in fluid communication with the first circulation pipe 100 . The buffer module 12 includes a first control valve 120 and a first storage space 121 . The first control valve 120 is located between the first circulation pipe 100 and the first storage space 121 . In the present application, the first storage space 121 may be constituted by a storage device such as a hollow liquid storage tank or a liquid storage barrel, which is used for storing or replenishing the first fluid L1.

For example, when the volume of the first fluid L1 increases due to an increase in ambient temperature, the first control valve 120 can be set to open, so that the first fluid L1 flows from the first circulation pipe 100 into the first storage space 121 . In this way, parameters such as the flow rate and pressure of the first fluid L1 in the first circulation pipe 100 can be adjusted according to preset or real-time settings. Conversely, when the ambient temperature suddenly drops and the volume of the first fluid L1 decreases, or the flow and pressure of the first fluid L1 need to be increased to improve heat dissipation performance, the first control valve 120 can also be set to open, so that part of the first fluid L1 flows into the first circulation pipe 100 from the first storage space 121 .

The control module 13 is electrically connected to the driving module 11 and the buffer module 12 , and the control module 13 includes a sensing device 130 . The control module 13 controls the first control valve 120 to open or close according to the first sensing signal S1 sent by the sensing device 130 , and controls the operation of the driving module 11 according to the first sensing signal S1 sent by the sensing device 130 .

Wherein, the fluid pressure sensor 130a is used for sensing the pressure of the first fluid L1 before being pressurized by the first driving pump 110a and/or the second driving pump 110b, the fluid pressure sensor 130b is used for sensing the pressure of the first fluid L1 after being pressurized by the first driving pump 110a and/or the second driving pump 110b, the fluid temperature sensor 130c is used for sensing the temperature of the first fluid L1 after absorbing the heat in the cabinet 2 (that is, the fluid return state), The temperature sensor 130d is used to sense the temperature of the first fluid L1 before absorbing the heat in the cabinet 2 (that is, the water outlet state), and the fluid flow meter 130e is used to sense the flow rate of the first fluid L1 in the first circulation pipe 100 .

Through the above configuration, the control module 13 can accurately confirm the state of the first fluid L1 in the first circulation pipe 100 to control the operation of the driving module 11 and/or the buffer module 12 in real time. When one or more of the temperature, pressure, and flow of the first fluid L1 is abnormal, the control module 13 sends a control signal C according to the first sensing signal S1 sent by the sensing devices 130 to control the driving module 11 to stop. operation, or control the opening/closing of the first control valve 120 to adjust the total amount of the first fluid L1 in the first circulation pipe 100 .

It is worth mentioning that the above configuration is only an embodiment of the present application, and the present application is not limited thereto. In other embodiments, other sensors of different types and quantities may also be arranged/connected to the first circulation pipe 100 to more effectively monitor the state of the heat exchange module 10 .

As shown in FIG. 1 , in some embodiments, the control module 13 includes an operation sub-module 131 and a recording sub-module 132 . The operation sub-module 131 receives the first sensing signal S1 from the sensing device 130 , generates a control signal C according to the first sensing signal S1 , and sends the control signal C to the buffer module 12 and/or the driving module 11 . For example, the operation sub-module 131 may include a central processing unit, a microprocessor and other suitable processors, which make judgments based on voltage information, current information, fluid pressure information, fluid temperature information, and fluid flow information in the first sensing signal S1, and generate a control signal C corresponding to the first sensing signal S1, so as to adjust the state of the first fluid L1 in the first circulation pipe 100 through the driving module 11 and/or buffer module 12.

When the information and fluid flow information are different from the above parameters, the operator module 131 can adjust the operation of the driving module 11 and/or the buffer module 12 according to the situation, and/or send an alarm to the maintenance personnel.

Please refer to FIG. 1 and FIG. 3 . FIG. 3 is a schematic diagram of a heat exchange system according to a first embodiment of the present application. As shown in the figure, in this embodiment, the heat exchange module 10 is used to absorb the heat of the cabinet 2 . Wherein, the heat exchange module 10 further includes a cooling device 101 , and the first circulation pipe 100 exchanges heat with the cooling device 101 . More specifically, the cooling device 101 includes a second circulation pipe 1010 and an ice water machine 1011. A part of the second circulation pipe 1010 is passed through the ice water machine 1011 to transfer heat to the ice water machine 1011. The first circulation pipe 100 exchanges heat with the second circulation pipe 1010 but is not in fluid communication. Wherein, the second fluid L2 is stored in the second circulation pipe 1010 . In this embodiment, the chilled water machine 1011 can be a large-scale chilled water machine 1011 in a commercial building or an industrial building, which is installed outside the building and performs heat exchange through a cooling water tower. However, the present application is not limited thereto, and the chiller 1011 may also be a dedicated cooler or a dedicated cooling tower, which may also be installed in a building.

By allowing the first fluid L1 and the second fluid L2 to flow through the first circulation pipe 100 and the second circulation pipe 1010 respectively, and making the first fluid L1 and the second fluid L2 close to each other (as shown in area A in FIG. 2 ) for heat exchange, this embodiment effectively conducts the heat in the cabinet 2 from the first fluid L1 and the second fluid L2 to the outside (for example, outside the building) in sequence. It is worth mentioning that the first fluid L1 and the second fluid L2 in this application only rely on heat conduction and heat radiation for heat exchange, at most by indirect heat convection (for example, the air that may flow in the area A) for heat exchange without actual fluid communication, so as to effectively prevent impurities and dirt from contaminating the first circulation pipe 100.

In some embodiments, the heat dissipation system of the present application can be divided into a primary side and a secondary side. Taking the right half of FIG. 3 as an example, components such as the control module 13 , the second circulation pipe 1010 , and the chiller 1011 are defined as a primary side fluid circuit. Taking the left half of FIG. 3 as an example, components such as the control module 13 , the first circulation pipe 100 , and the cabinet 2 are defined as the secondary side fluid circuit. That is to say, this embodiment can actually be regarded as composed of left and right side fluid circuit. Therefore, the term “second” related to the first set of fluid circuits in this application may also be referred to as “primary side”. For example, elements such as the "second" circulation pipe 1010, the "second" fluid L2, and the "second" filter f2 may be referred to as the "primary" circulation pipe, the "primary" fluid, and the "primary" filter.

Similarly, the term "first" related to the second set of fluid circuits in this application may also be referred to as "secondary side". For example, elements such as the "first" circulation pipe 100, the "first" fluid L1, the "first" control valve 120, the "first" storage space 121, the "first" sensing signal S1, and the "first" filter f1 may be referred to as the "secondary side" circulation pipe, the "secondary side" fluid, the "secondary side" control valve, the "secondary side" storage space, and the "secondary side" filter.

Apparently, the terms “first”, “second”, “primary side” and “secondary side” used in this application are only used to distinguish different elements or components, and should not be understood as indicating or implying relative importance or sequence relationship thereof.

In some embodiments, the second fluid L2 may include water, ethylene glycol aqueous solution, but not limited thereto. Preferably, the second fluid L2 may also contain deionized water. More preferably, the second fluid L2 is deionized water added with anticorrosion inhibitors and bactericides. Still more preferably, the second fluid L2 may be the same as the first fluid L1 satisfying the conditions in the above table.

Taking the schematic diagram of FIG. 2 as an example, in the left half representing the second circulation pipe 1010, the second circulation pipe 1010 may also be provided/connected with sensing devices 130 such as a fluid pressure sensor 130g, a fluid pressure sensor 130h, a fluid temperature sensor 130f, and a fluid flow meter 130i. Among them, the fluid pressure sensor 130g is used to sense the pressure of the second fluid L2, the fluid pressure sensor 130h is used to sense the pressure of the second fluid L2, and the fluid temperature sensor 130f is used to sense the second fluid L2 after absorbing the heat of the first fluid L1 temperature (that is, the return water state), and the fluid flow meter 130i is used to sense the flow rate of the second fluid L2 in the second circulation pipe 1010 .

In some embodiments, the heat exchange system 1 may further include a filter, and the filter may be arranged on the first circulation pipe 100 and/or the second circulation pipe 1010 to effectively filter impurities in the pipeline. For example, the first circulation pipe 100 and the second circulation pipe 1010 may be provided with a first filter f1 and a second filter f2 respectively, which are arranged at the positions shown in FIG. 2 . However, the present application is not limited thereto, and those skilled in the art can set filters with different filtering levels according to requirements, and can also set these filters at positions different from those shown in FIG. 2 .

Based on the above, the heat exchange system 1 in this embodiment adopts the connection method of FIG. 3 , which monitors the entire heat exchange process through the control module 13 located between the cooling device 101 and the cabinet 2, so that the cabinet 2 can be in a preset working environment effectively and stably. It is worth mentioning that although FIG. 3 shows that the control module 13 is located outside the cabinet 2 , the actual configuration is not limited thereto. For example, when the size of the control module 13 and the buffer module 12 is small, all components in the heat exchange system 1 except the second circulation pipe 1010 of the heat exchange module 10 and the cooling device 101 can be located in the cabinet 2, so as to greatly reduce the occupied volume of the entire heat exchange system 1. However, when the size of the control module 13 and the buffer module 12 is large, all components in the heat exchange system 1 except a part of the first circulation pipe 100 of the heat exchange module 10 can be located outside the cabinet 2 . Therefore, the present embodiment is not limited to the specific positions of the physical components, but only illustrates the relative relationship and functions of the various components.

In addition, the heat exchange system 1 of the present application is not limited to be matched with the cooling device 101 (ie, the chiller 1011 ) of the building. Hereinafter, the present application will further provide different connection modes to illustrate different aspects that the heat exchange system 1 of the present application can implement.

Please refer to FIG. 4 and FIG. 5 , which are respectively a block diagram and a schematic diagram of a heat exchange system according to a second embodiment of the present application. In this embodiment, the reference numerals in FIG. 4 have similar or identical functions to the same reference numerals in FIG. 1 to FIG. 3 , or are composed of similar or identical materials. For detailed descriptions, refer to the above, and will not be repeated here. In this embodiment, the cooling device 101 includes a plurality of cooling fins 1012 , and the first circulation tube 100 exchanges heat with the plurality of cooling fins 1012 . In other words, the cooling device 101 of this embodiment is not a chiller or a cooling water tower of a building, and the first circulation pipe 100 does not exchange heat with the chiller 1011 through the second circulation pipe 1010 . Furthermore, the first circulation tube 100 of this embodiment exchanges heat with the air through air cooling (for example, directly through the cooling fins 1012 ). In this case, the heat exchange system 1 can effectively discharge the heat in the cabinet 2 directly to the environment. It is worth mentioning that when the pipeline of the first circulation pipe 100 is long enough, the cooling fins 1012 can be located in an environment different from that of the cabinet 2 .

Based on the above, the heat exchange system 1 in this embodiment adopts the connection method shown in FIG. 5 , which monitors the entire heat exchange process through the control module 13, so that the cabinet 2 can be placed in a preset working environment effectively and stably. Besides, in this embodiment, only the first circulation tube 100 and the cooling fins 1012 are used for heat transfer. Without using the second circulation pipe 1010 and the chiller 1011 , this embodiment effectively reduces the occupied volume of the entire heat exchange system 1 .

Please refer to FIG. 6 , which is a block diagram of a heat exchange system according to a third embodiment of the present application. In this embodiment, the reference numerals in FIG. 6 have similar or identical functions to the same reference numerals in FIG. 1 to FIG. 3 , or are composed of similar or identical materials.

The compression heat exchange component 1013 is arranged in the second circulation pipe 1010 and compresses the second circulation pipe 1010 The second fluid L2 in. The plurality of cooling fins 1014 exchange heat with the second circulation tube 1010 .

In this embodiment, the cooling device 101 adopts a heat dissipation mode similar to a refrigerator (ie, a Carnot refrigerator). Specifically, the cooling device 101 effectively transfers heat from a low temperature place to a high temperature place through processes such as isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression in sequence. In this way, the heat exchange system 1 of this embodiment can quickly dissipate the heat in the cabinet 2 similarly to an air-conditioning system, and is less limited by the ambient temperature of the discharge. It is worth mentioning that the above-mentioned elements are only examples, and the present application is not limited thereto.

For example, the heat exchange module 10 , the drive module 11 , the buffer module 12 and the control module 13 in the entire heat exchange system 1 can be located in the cabinet 2 or on the cabinet 2 at the same time. In other words, the cabinet 2 can directly dissipate heat through the heat exchange system 1 installed inside/on it, without being additionally connected to a cooling water tower or other cooling devices of the building. In this way, the installation locations of the cabinet 2 can be more diverse. It is worth mentioning that the above setting manner is only an example, and the present application is not limited thereto. In some embodiments, one or more of the heat exchange module 10 , the drive module 11 , the buffer module 12 and the control module 13 may be disposed outside the cabinet 2 .

In some embodiments, the sensor may include one or more of a voltage sensing element, a current sensing element, a fluid temperature sensing element, a fluid pressure sensing element, a fluid flow element, and/or various types of sensing elements known to those skilled in the art to effectively monitor The state of the heat exchange module 10. Specifically, the fluid temperature sensing element, the fluid pressure sensing element, the fluid flow element, and other suitable sensing elements will generate a second sensing signal according to the measured state of the second fluid L2. The second sensing signal may include voltage information, current information, fluid pressure information, fluid temperature information, and fluid flow information, but not limited thereto.

In some embodiments, the cooling device 101 further includes a buffer assembly 1016, the buffer assembly 1016 is fluidly connected to the second circulation pipe 1010, the buffer assembly 1016 includes a second control valve and a second storage space, the second control valve is located between the second circulation pipe 1010 and the storage space, and the control assembly 1015 controls the second control valve to open or close according to the second sensing signal sent by the sensor. Similar to the function of the buffer module 12, the buffer component 1016 of this embodiment is also provided to maintain the flow rate and volume of the second fluid L2 in a better working environment.
