Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, a block diagram of a heat exchange system according to a first embodiment of the present application is shown. As shown, the heat exchange system 1 includes a heat exchange module 10, a driving module 11, a buffering module 12, and a control module 13.
The heat exchange module 10 includes a first circulation tube 100, a portion of the first circulation tube 100 being disposed through the cabinet to remove heat from the cabinet. Wherein the first circulation pipe 100 stores therein a first fluid L1. In the present application, the term "cabinet" refers to a carrier in which servers are disposed. For example, the enclosure may be a server carrier located in a computer room, and the servers may include, but are not limited to, central processing units, graphics processors, hard disks, power supplies, memory, and the like. However, the present application is not limited to the place where the cabinet is disposed. By penetrating a portion of the first circulation pipe 100 into the cabinet, the first fluid L1 flowing along the first circulation pipe 100 can effectively carry away heat in the cabinet to maintain a stable operating temperature of the cabinet. It should be noted that "penetrating" in the above description means that a portion of the first circulation tube 100 is located in the cabinet, and the first circulation tube 100 located in the cabinet may be further connected or connected in series with a large-area heat dissipating block, a heat dissipating plate, and heat dissipating fins to increase the heat exchange rate.
In some embodiments, the first fluid L1 may be water, an aqueous glycol solution, or a compatible cooling fluid. Preferably, the first fluid L1 may be deionized water. More preferably, the first fluid L1 is deionized water with added corrosion inhibitor and bactericide to reduce corrosion, scaling and microbial growth of the pipeline, thereby reducing heat dissipation capability 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 ℃ to 45 ℃, which needs to be above the ambient dew point.
The driving module 11 is connected to the heat exchange module 10 and configured to drive the first fluid L1 in the first circulation pipe 100 to flow along the pipe. In some embodiments, the driving module 11 includes a driving pump 110, the driving pump 110 being disposed in the first circulation pipe 100 and driving the first fluid L1 in the first circulation pipe 100. For example, the actuation pump 110 may be a plunger pump in a test pump that uses a relief valve to control pressure and a throttle valve to control flow. However, the present application is not limited thereto, and pumps known to those skilled in the art may be applied to the present application. For example, the drive pump 110 may also be a metering pump, or other suitable pump.
In some embodiments, the plurality of drive pumps 110, at least one of the plurality of drive pumps 110 is in an operational state, and at least one of the plurality of drive pumps 110 is in a closed state. Please refer to fig. 2, which is a schematic diagram illustrating a pipeline configuration of a heat exchange system according to a first embodiment of the present application, and a right half of fig. 2 is a schematic diagram illustrating a portion of the first circulation pipe 100. Taking the present embodiment as an example, the number of the driving pumps 110 may be two, and two driving pumps 110 (i.e., the first driving pump 110a and the second driving pump 110 b) are respectively connected in series in the first circulation pipe 100. When one of the two drive pumps 110 is in an operating state, the other of the two drive pumps 110 is in a closed state. In this way, the whole driving module 11 drives the delivery of the first fluid L1 by only one driving pump 110, while the other driving pump 110 is used for standby. In this case, the two driving pumps 110 may be alternately turned off at a fixed period to increase the lifetime of the apparatus. In addition, by means of the alternate activation design, the drive module 11 can be made such that it does not affect the operation of the heat exchange system 1 during repair/maintenance. It should be noted that the above number is only an example, and the number of the driving pumps 110 in other embodiments may be three, four, or more than four, and it is consistent that at least one of the driving pumps 110 is in the off state.
The buffer module 12 is in fluid communication with the first circulation tube 100, and the buffer module 12 includes a first control valve 120 and a first storage space 121, the first control valve 120 being located between the first circulation tube 100 and the first storage space 121. In the present application, the first storage space 121 may be formed by a hollow storage device such as a liquid tank, or the like, for storing or replenishing the first fluid L1.
For example, when the ambient temperature increases to cause the volume of the first fluid L1 to increase, the first control valve 120 may be set to be opened to allow the first fluid L1 to flow from the first circulation pipe 100 into the first storage space 121. In this way, the flow rate, pressure, etc. of the first fluid L1 in the first circulation pipe 100 can be adjusted according to the preset or real-time setting. Conversely, when the ambient temperature suddenly drops to decrease the volume of the first fluid L1, or the flow rate and pressure of the first fluid L1 need to be increased to improve the heat dissipation performance, the first control valve 120 may be set to be opened to allow a portion of the first fluid L1 to enter from the first storage space 121 and flow into the first circulation pipe 100.
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 driving module 11 to operate according to the first sensing signal S1 sent by the sensing device 130. In some embodiments, sensing device 130 may include one or more of a voltage sensor, a current sensor, a fluid temperature sensor, a fluid pressure sensor, a fluid flow meter, and/or various types of sensors known to those skilled in the art to effectively monitor the status of heat exchange module 10. Specifically, the fluid temperature sensor, the fluid pressure sensor, the fluid flowmeter, and other suitable sensors generate a first sensing signal S1 according to the measured state of the first fluid L1, and the first sensing signal S1 may include, but is not limited to, voltage data, current data, fluid pressure data, fluid temperature data, and fluid flow data.
Taking the schematic diagram of fig. 2 as an example, in the right half representing the first circulation pipe 100, the first circulation pipe 100 may be provided with/connected with sensing devices 130 such as a fluid pressure sensor 130a, a fluid pressure sensor 130b, a fluid temperature sensor 130c, a fluid temperature sensor 130d, and a fluid flow meter 130e, and driving pumps 110 such as a first driving pump 110a and a second driving pump 110 b.
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 (i.e. backwater state) of the first fluid L1 after absorbing heat in the cabinet 2, the fluid temperature sensor 130d is used for sensing the temperature (i.e. water outlet state) of the first fluid L1 before absorbing heat in the cabinet 2, and the fluid flow meter 130e is used for sensing the flow rate of the first fluid L1 in the first circulation pipe 100.
With the above arrangement, the control module 13 can precisely confirm the state of the first fluid L1 in the first circulation pipe 100 to instantly control the operation of the driving module 11 and/or the buffer module 12. When one or more of the temperature, pressure and flow rate of the first fluid L1 is abnormal, the control module 13 sends a control signal C according to the first sensing signals S1 sent by the sensing devices 130 to control the driving module 11 to stop operating or control the first control valve 120 to open/close so as to adjust the total amount of the first fluid L1 in the first circulation pipe 100.
It should be noted that the above configuration is only one embodiment of the present application, and the present application is not limited thereto. In other embodiments, other different types and numbers of sensors may be provided/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 operator sub-module 131 and a record sub-module 132. The operation sub-module 131 receives the first sensing signal S1 from the sensing device 130, generates the 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 processor, a micro processor, or other suitable processor, which determines according to the voltage data, the current data, the fluid pressure data, the fluid temperature data, the fluid flow data, and the like in the first sensing signal S1, and generates the control signal C corresponding to the first sensing signal S1 to adjust the state of the first fluid L1 in the first circulation pipe 100 through the driving module 11 and/or the buffer module 12.
The recording sub-module 132 receives the first sensing signal S1 from the sensing device 130, and stores Chu Diyi the voltage data, the current data, the fluid pressure data, the fluid temperature data, and the fluid flow data in the sensing signal S1. In the present application, the recording sub-module 132 may include a conventional hard disk (HDD), a solid state disk (SDD), a Random Access Memory (RAM), an optical storage device (CD, DVD), or other suitable storage device to record the above data in the first sensing signal S1.
In some embodiments, the recording sub-module 132 can also store predetermined voltage data, predetermined current data, predetermined fluid pressure data, predetermined fluid temperature data and predetermined fluid flow data, and when the operator module 131 determines that the detected voltage data, current data, fluid pressure data, fluid temperature data and fluid flow data 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.
Referring to fig. 1 and 3, fig. 3 is a schematic diagram of a heat exchange system according to a first embodiment of the application. As shown, in the present embodiment, the heat exchange module 10 is used to extract heat from the cabinet 2. Wherein the heat exchange module 10 further comprises a cooling device 101, and the first circulation pipe 100 exchanges heat with the cooling device 101. More specifically, the cooling apparatus 101 includes a second circulation pipe 1010 and an ice water machine 1011, a portion of the second circulation pipe 1010 penetrating into the ice water machine 1011 to transfer heat into the ice water machine 1011, the first circulation pipe 100 being in heat exchange but not fluid communication with the second circulation pipe 1010. Wherein the second circulation tube 1010 stores a second fluid L2 therein. In this embodiment, the water chiller 1011 may be a large water chiller 1011 installed outside a building and performing heat exchange through a heat-dissipating water tower. However, the present application is not limited thereto, and the ice water machine 1011 may be a dedicated cooler or a dedicated cooling tower, which may 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 allowing the first fluid L1 and the second fluid L2 to approach each other (as the region a in fig. 2) for heat exchange, the present embodiment effectively conducts the heat in the cabinet 2 from the first fluid L1 and the second fluid L2 to the outside (e.g. outside the building) in sequence. It should be noted that the first fluid L1 and the second fluid L2 in the present application exchange heat only by heat conduction and heat radiation, and at most exchange heat by indirect heat convection (e.g., air possibly flowing in the area a) without actually being in fluid communication, so as to effectively avoid impurities and dirt from contaminating the first circulation pipe 100.
In some embodiments, the heat dissipation system of the present application may be divided into a primary side and a secondary side. Taking the right half of fig. 3 as an example, the components of the control module 13, the second circulation pipe 1010, the ice water machine 1011, and the like are defined as a primary side fluid circuit. Taking the left half of fig. 3 as an example, the components of the control module 13, the first circulation pipe 100, the cabinet 2, and the like are defined as a secondary side fluid circuit. That is, the present embodiment can be regarded as actually composed of the fluid circuits on the left and right sides. Accordingly, the term "second" in connection with the first set of fluid circuits of the present application may also be referred to as "primary side". For example, the elements of the "second" circulation tube 1010, the "second" fluid L2, and the "second" filter f2 may be referred to as "primary side" circulation tubes, the "primary side" fluid, and the "primary side" filter.
Similarly, the term "first" in connection with the second set of fluid circuits of the present application may also be referred to as "secondary side". For example, the components of the "first" circulation tube 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 tube, the "secondary side" fluid, the "secondary side" control valve, the "secondary side" storage space, and the "secondary side" filter.
It should be appreciated that the terms "first," "second," "primary" and "secondary" are used herein merely to distinguish between different elements or components, and are not to be construed as indicating or implying relative importance or a sequential relationship thereof.
In some embodiments, the second fluid L2 may include water, an aqueous glycol solution, but is not limited thereto. Preferably, the second fluid L2 may also comprise deionized water. More preferably, the second fluid L2 is deionized water to which a corrosion inhibitor and a bactericide are added. Still more preferably, the second fluid L2 may be identical to 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, a sensing device 130 such as a fluid pressure sensor 130g, a fluid pressure sensor 130h, a fluid temperature sensor 130f, and a fluid flow meter 130i may also be provided/connected to the second circulation pipe 1010. Wherein 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, the fluid temperature sensor 130f is used to sense the temperature (i.e., the backwater state) of the second fluid L2 after the heat of the first fluid L1 is extracted, 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, which may be provided on the first circulation pipe 100 and/or the second circulation pipe 1010 to effectively filter impurities in the piping. For example, the first and second circulation pipes 100 and 1010 may be provided with first and second filters f1 and f2, respectively, which are disposed at positions as shown in fig. 2. However, the present application is not limited thereto, and one skilled in the art may set filters with different filtering levels according to the requirements, and may set the filters at different positions from fig. 2.
As described above, the heat exchange system 1 in this embodiment adopts the connection mode of fig. 3, which monitors the whole heat exchange process through the control module 13 located between the cooling device 101 and the cabinet 2, so as to effectively and stably enable the cabinet 2 to be in a preset working environment. It should be noted that although fig. 3 illustrates the control module 13 located outside the cabinet 2, the actual configuration is not limited thereto. For example, when the dimensions of the control module 13 and the buffer module 12 are small, all the elements of 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 whole heat exchange system 1. However, when the sizes of the control module 13, the buffer module 12 are large, all elements of the heat exchange system 1 except for a portion of the first circulation pipe 100 of the heat exchange module 10 may be located outside the cabinet 2. Therefore, the present embodiment is not limited to the specific locations of the physical elements, but merely illustrates the relative relationships and functions between the elements.
In addition, the heat exchange system 1 of the present application is not limited to be used with the cooling device 101 (i.e., the chiller 1011) of the building. In the following, the application will further provide different ways of connection to illustrate different aspects of the heat exchange system 1 according to the application that can be implemented.
Please refer to fig. 4 and 5, which are 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 same reference numerals in fig. 4 and fig. 1 to 3 have similar or identical functions or are made of similar or identical materials, and the detailed description thereof will be given above without further description. In the present embodiment, the cooling device 101 includes a plurality of heat radiating fins 1012, and the first circulation pipe 100 is in heat exchange with the plurality of heat radiating fins 1012. In other words, the cooling device 101 of the present embodiment is not a water chiller or a cooling water tower of a building, and the first circulation pipe 100 does not exchange heat with the ice water chiller 1011 through the second circulation pipe 1010. Further, the first circulation tube 100 of the present embodiment performs heat exchange with air by air cooling (e.g., directly through the heat dissipation fins 1012). In this case, the heat exchange system 1 can effectively discharge the heat in the cabinet 2 directly to the environment. It should be noted that when the piping of the first circulation pipe 100 is long enough, the heat dissipation fins 1012 can be located in an environment different from the environment of the cabinet 2.
As described above, the heat exchange system 1 in this embodiment adopts the connection mode of fig. 5, which monitors the whole heat exchange process through the control module 13, so as to effectively and stably enable the cabinet 2 to be in a preset working environment. In addition, only the first circulation tube 100 and the heat radiating fins 1012 are used for heat transfer in the present embodiment. Without using the second circulation pipe 1010 and the ice water machine 1011, the present embodiment effectively reduces the occupied volume of the entire heat exchange system 1.
Referring to fig. 6, a block diagram of a heat exchange system according to a third embodiment of the present application is shown. In this embodiment, the same reference numerals in fig. 6 and fig. 1 to 3 have similar or identical functions or are made of similar or identical materials, and the detailed description thereof will be given above without further description. In the present embodiment, the cooling device 101 includes a second circulation pipe 1010, a compression heat exchange unit 1013, a plurality of heat dissipation fins 1014, and a control unit 1015. The second circulation tube 1010 is in heat exchange but not fluid communication with the first circulation tube 100. The compression heat exchange unit 1013 is provided in the second circulation pipe 1010 and compresses the second fluid L2 in the second circulation pipe 1010. The plurality of heat radiating fins 1014 are in heat exchange with the second circulation tube 1010. The control unit 1015 is electrically connected to the compression heat exchange unit 1013, the control unit 1015 includes a sensor, and the control unit 1015 controls the compression heat exchange unit 1013 to operate according to a second sensing signal sent by the sensor.
In the present embodiment, the cooling device 101 adopts a heat radiation mode similar to that of a refrigerator (i.e., a carnot refrigerator). Specifically, the cooling device 101 effectively transfers heat from a low temperature to a high temperature through isothermal expansion, adiabatic expansion, isothermal compression, adiabatic compression, and the like in sequence. As a result, the heat exchange system 1 of the present embodiment can quickly remove heat from the cabinet 2 similar to an air conditioning system, and is less limited by the discharged ambient temperature. It is worth mentioning that the above mentioned elements are only examples, and the application is not limited thereto. Any desired or suitable elements may be provided as desired by those skilled in the art.
In the present embodiment, the heat exchange module 10, the driving module 11, the buffer module 12 and the control module 13 in the entire heat exchange system 1 may be a complete heat dissipation device, rather than being composed of a plurality of components separately provided. For example, the heat exchange module 10, the driving module 11, the buffer module 12 and the control module 13 in the entire heat exchange system 1 may be located in the cabinet 2 or on the cabinet 2 at the same time. In other words, the cabinet 2 can directly radiate heat through the heat exchange system 1 installed therein/thereon without an additional cooling tower or other cooling device connected to the building. In this way, the installation place of the cabinet 2 can be more diversified. It should be noted that the above arrangement 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 status of the heat exchange module 10. Specifically, the fluid temperature sensor, the fluid pressure sensor, the fluid flow sensor, and other suitable sensor generate a second sensor signal according to the measured state of the second fluid L2, where the second sensor signal may include, but is not limited to, voltage data, current data, fluid pressure data, fluid temperature data, and fluid flow data.
In some embodiments, the cooling device 101 further includes a buffer assembly 1016, the buffer assembly 1016 is in fluid communication with 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 second storage space, and the control assembly 1015 controls the second control valve to be opened or closed according to a second sensing signal sent by the sensor. Similar to the function of the buffer module 12, the buffer module 1016 of the present embodiment is also provided to maintain the flow rate and volume of the second fluid L2 in a preferred working environment. For detailed description, reference may be made to the above, and no further description is given here.
In some embodiments, the plurality of compression heat exchange assemblies 1013, at least one of the plurality of compression heat exchange assemblies 1013 is in an operating state, and at least one of the plurality of compression heat exchange assemblies 1013 is in a closed state. Similar to the drive pump 110 described above, by the alternate activation design, the compression heat exchange assembly 1013 can be made without affecting the operation of the heat exchange system 1 during repair/maintenance. It should be noted that the above number is only an example, and the number of the compression heat exchange assemblies 1013 in other embodiments may be three, four, or more than four, and it is consistent that at least one of the compression heat exchange assemblies 1013 is in the off state.
In summary, the heat exchange system may monitor the first fluid in the first circulation pipe in real time through the sensing device in the control module, and determine whether the pressure and the temperature of the first fluid conform to the preset state according to the first sensing signal returned by the sensing device. When the pressure, temperature, etc. of the first fluid changes, the control module can adjust the state of the first fluid through the driving module, and even store excessive first fluid through the storage module to maintain stable thermal cycle. Therefore, through the arrangement, the heat exchange system can effectively dissipate heat and continuously and stably run.
