Description

Technical Field

[0001] This application relates to the field of heat dissipation in power distribution and energy storage cabinets, and in particular to an environmentally adaptive intelligent control device and control method for outdoor energy storage prefabricated cabins. Background Technology

[0002] The flywheel-electrochemical hybrid energy storage relies on the synergistic logic of "flywheel handling instantaneous peak loads and electrochemical ensuring continuous output," combining the advantages of flywheel's millisecond-level attenuation-free high-frequency response and electrochemical's long-term stable output. The overall system efficiency can reach over 90%, making it widely applicable to scenarios such as grid frequency regulation and new energy consumption.

[0003] However, existing outdoor energy storage prefabricated cabin heat dissipation technologies mostly adopt a single, fixed air-cooling or water-cooling heat dissipation mode, which cannot adapt to the different heat source characteristics of flywheel pulse instantaneous high heat and electrochemical cell steady-state continuous heat dissipation, and cannot adaptively adjust the heat dissipation mode according to the operating temperature. To address this, an environmentally adaptive intelligent control device and control method for outdoor energy storage prefabricated cabins are proposed. Summary of the Invention

[0004] The purpose of this application is to address the technical problem of existing outdoor energy storage prefabricated cabins having a single heat dissipation method and poor heat dissipation adaptability. Compared with the existing technology, this application provides an environmentally adaptive intelligent control device for outdoor energy storage prefabricated cabins, including: The prefabricated power distribution cabinet has a built-in flywheel compartment. Several battery isolation compartments are arranged side by side on one side of the flywheel compartment. The battery isolation compartment is a horizontal through-slot. The prefabricated power distribution cabinet has a negative pressure interlayer on the upper side and a positive pressure interlayer on the lower side. A heat dissipation side cabinet is detachably installed on one side of a prefabricated power distribution cabinet. The heat dissipation side cabinet is equipped with a negative pressure fan, a positive pressure fan and a circulating pump. The input end of the negative pressure fan is connected to the negative pressure interlayer, and the output end of the positive pressure fan is connected to the positive pressure interlayer. The battery energy storage module consists of energy storage cells arranged at intervals. Two sets of battery energy storage modules are inserted into each other in the same battery isolation compartment, and the energy storage cells of the two sets of battery energy storage modules are arranged alternately. The flywheel energy storage module is located inside the flywheel compartment; The conductive heat pipe is snake-shaped and interspersed between adjacent energy storage cells on the same horizontal plane. Several air guide grooves are formed at equal intervals on the conductive heat pipe. A docking air vent groove is provided in the same battery isolation compartment, and the docking air vent groove connects to the corresponding upper and lower air guide grooves. The uppermost air guide groove connects to the negative pressure interlayer input end, and the lowermost air guide groove connects to the positive pressure interlayer output end. The conductive heat pipe has strip-shaped channels on both sides of the air guide groove, and upper liquid channels and lower liquid channels are respectively opened on the upper and lower sides of the strip channels. The liquid cooling circulation module is located inside the heat dissipation cabinet and is used to supply circulating coolant to the upper and lower liquid channels. The control unit is located on one side of the outer wall of the flywheel compartment.

[0005] Furthermore, the number of air guide slots is equal to the number of battery isolation chambers arranged in the horizontal direction, and the number of heat conduction tubes is equal to the number of battery isolation chambers arranged in the vertical direction. The inner wall of the air guide trough is fixed with several heat dissipation fins arranged at equal intervals.

[0006] Furthermore, the liquid cooling circulation module includes an annular air guide seat, on which several spiral liquid storage tanks are assembled, and several heat dissipation fins are fixed to the outer wall of the spiral liquid storage tanks. The number of spiral storage tanks is twice the number of conductive heat lines.

[0007] Furthermore, a three-position three-way valve is installed at the output end of the negative pressure fan. The first passage of the three-position three-way valve is connected to the negative pressure jacket, the second passage is connected to the top of the liquid cooling circulation module, and the third passage is connected to both the negative pressure jacket and the top of the liquid cooling circulation module. The output end of the positive pressure fan is equipped with a lower three-way valve. The first passage of the lower three-way valve is connected to the positive pressure jacket, the second passage is connected to the bottom of the liquid cooling circulation module, and the third passage is connected to both the positive pressure jacket and the bottom of the liquid cooling circulation module. The upper three-position three-way valve and the lower three-position three-way valve can switch between three working modes: independent air-cooled passage, air-cooled auxiliary liquid-cooled heat dissipation passage, and independent liquid-cooled passage.

[0008] Furthermore, the strip-shaped channel is located between the upper liquid channel and the lower liquid channel; two sets of beryllium copper spring plates are symmetrically fixed inside the strip-shaped channel. At room temperature, the two sets of beryllium copper spring plates move closer together and close, so that the strip-shaped channel is closed and separates the upper liquid channel and the lower liquid channel on the same side. After being heated, the elasticity of the beryllium copper spring plates decreases and they move away from each other, so that the strip-shaped channel opens and connects the upper liquid channel and the lower liquid channel on the same side. The beryllium copper spring plate and the inner wall of the strip channel form a liquid storage chamber, which is filled with phase change liquid. When the beryllium copper spring plate is heated, the phase change liquid becomes liquid, which absorbs heat and provides space for the deformation of the beryllium copper spring plate. When the temperature drops, the beryllium copper spring plate returns to its original elasticity and squeezes against each other, and the phase change liquid turns into solid, providing the compressive support force for the beryllium copper spring plate.

[0009] Furthermore, a flow regulating valve is installed at the end of the heat conduction cable away from the circulating pump. The flow regulating valve includes a flow regulating valve chamber fixed to the end of the heat conduction cable. The strip-shaped channel, upper liquid channel, and lower liquid channel at the end of the heat conduction cable all extend into the interior of the flow regulating valve chamber. The flow direction valve core is rotatably assembled in the flow direction valve chamber; the flow direction valve core is provided with symmetrically arranged upper and lower flow direction holes on one side, and a flow direction channel is opened inside the valve core to connect the upper and lower flow direction holes on the same side. The upper and lower flow direction holes on the same side are respectively aligned and connected to the corresponding upper and lower liquid channels. A parallel flow valve groove is opened on the other side of the valve core, and the width of the parallel flow valve groove is adapted to the center distance between the two strip channels; The rotary flow valve core can switch between two paths. When the temperature is ≤35℃, the upper and lower flow holes connect to the upper and lower liquid channels, and the upper and lower liquid channels on the same side are connected through the flow channel to realize small-flow independent circulation of the upper and lower liquid channels on the same side. When the temperature is greater than 35℃, the strip channel is fully opened and connected to the upper and lower liquid channels on the same side. At this time, the parallel flow valve groove flowing to the valve core connects to the strip channels on both sides of the heat conduction cable, realizing a large-flow independent circulation with the strip channels on both sides connected.

[0010] Furthermore, a circulation regulating valve is installed at one end of the heat conduction tape near the circulation pump. The circulation regulating valve includes a circulation valve chamber fixed to the end of the heat conduction tape, and the strip-shaped channel, upper liquid channel, and lower liquid channel at the other end of the heat conduction tape extend into the circulation valve chamber. The circulating valve core is rotatably installed inside the circulating valve chamber. The upper and lower parts of the circulating valve core are respectively formed as a return liquid chamber and a supply liquid chamber. The top of the circulating valve core has a return liquid interface that connects to the return liquid chamber, and the bottom has a supply liquid interface that connects to the supply liquid chamber. The circulating valve core has a return liquid upper parallel flow port and a supply liquid lower parallel flow port arranged vertically on one side. The return liquid upper parallel flow port is connected to the return liquid chamber, and the supply liquid lower parallel flow port is connected to the supply liquid chamber. The width of the return liquid upper parallel flow port matches the spacing between the two sets of upper liquid channels, and the width of the supply liquid lower parallel flow port matches the spacing between the two sets of lower liquid channels. The other side of the circulation valve core is provided with symmetrically arranged return side valve slots and supply side valve slots, and the distance between the two valve slots is adapted to the distance between the two strip channels; the return side valve slot is connected to the return liquid chamber, and the supply side valve slot is connected to the supply liquid chamber.

[0011] Furthermore, the liquid supply interface input is connected to the circulation pump output, and the circulation pump input is connected to the bottom of the spiral liquid storage tank; the liquid return interface output is connected to the top of the spiral liquid storage tank, forming a closed coolant circulation loop.

[0012] Furthermore, the flow valve core and the circulation valve core are driven to rotate by servo motors; a temperature sensor for collecting the temperature inside the battery isolation chamber is installed inside the chamber; the servo motor, temperature sensor, negative pressure fan, upper three-way valve, positive pressure fan, lower three-way valve, and circulation pump are all electrically connected to the control unit, and the control unit adaptively switches between air cooling, water cooling, and air-liquid composite heat dissipation modes according to the collected temperature.

[0013] An environmentally adaptive intelligent control method for outdoor energy storage prefabricated cabins includes the following steps: S1. Real-time monitoring: The temperature signal inside the battery isolation compartment is collected in real time by a temperature sensor and transmitted to the control unit in real time; S2, Intelligent Matching: The control unit combines the instantaneous pulse heating characteristics of the flywheel energy storage module with the steady-state continuous heating characteristics of the battery energy storage module to determine the real-time temperature conditions inside the cabin; S3, Coordinated Control: The control unit coordinates the start-stop and gear adjustment of the servo motor, upper three-position three-way valve, lower three-position three-way valve, negative pressure fan, positive pressure fan and circulation pump, and adaptively switches between three heat dissipation working modes: air cooling, liquid cooling and air-liquid hybrid. S4. Adaptive flow regulation: While switching the heat dissipation mode, the linkage flow direction regulating valve and circulation regulating valve adaptively adjust the coolant circulation flow to match the real-time heat dissipation requirements and realize intelligent constant temperature control of the prefabricated cabin in all outdoor working conditions.

[0014] Compared to existing technologies, the advantages of this application are: This invention forms a full-area air-cooled air duct through positive and negative pressure interlayers, a serpentine interlacing air guide groove between energy storage cells, and a multi-channel liquid cooling structure heat conduction tape. It is equipped with a three-position three-way valve to switch between three heat dissipation modes: pure air cooling, air-liquid hybrid cooling, and pure liquid cooling. Passive temperature control is achieved through beryllium copper spring plates and phase change fluid. Combined with double-ended flow direction regulating valves and circulation regulating valves, it can adaptively switch between large and small flow liquid cooling circulation loops. It can achieve differentiated adaptive heat dissipation control according to different extreme outdoor environmental temperatures, and is suitable for all outdoor working conditions such as high cold, high temperature, and high altitude. Meanwhile, the modular and split structure of this invention has convenient installation and transportation capabilities as well as fault-tolerant operation and maintenance capabilities. The heat dissipation side cabinet is independently detachable, and the assembly and transportation of the whole machine does not require large hoisting equipment, making it suitable for complex outdoor construction sites. Each heat dissipation circuit and energy storage module is independent of each other. When a single component such as the negative pressure fan, positive pressure fan, circulating pump, flow direction regulating valve, circulation regulating valve, or single set of heat conduction cable is damaged, the remaining heat dissipation circuits and energy storage units can operate normally and independently without causing the whole machine to shut down. It has strong fault-tolerant operation capabilities, convenient maintenance and replacement, and significantly reduces operation and maintenance costs. Attached Figure Description

Detailed Implementation

[0017] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0018] Example 1: This invention provides an environmentally adaptive intelligent control device for outdoor energy storage prefabricated cabins. Please refer to [link / reference]. Figure 1 - Figure 20 It includes a prefabricated power distribution cabinet 1, with an independent flywheel compartment 14 inside the prefabricated power distribution cabinet 1. Several battery isolation compartments 13 are arranged side by side on the side of the flywheel compartment 14. The battery isolation compartments 13 adopt a horizontal through-slot structure to provide assembly space for energy storage components.

[0019] Please refer to this first. Figure 1 The prefabricated power distribution cabinet 1 adopts a layered heat dissipation structure, with a negative pressure interlayer 11 at the top and a positive pressure interlayer 12 at the bottom, forming the basic structure of the cabin's full-area air-cooled duct. The prefabricated power distribution cabinet 1 has a detachable heat dissipation side cabinet 2 on one side. The detachable structure design allows the heat dissipation side cabinet 2 to be transported, disassembled, and repaired independently without the need to hoist the prefabricated power distribution cabinet 1 as a whole, greatly reducing the difficulty of transporting outdoor equipment and installing it on site. At the same time, if a single component is damaged, it can be replaced individually without affecting the operation of the whole machine, and the fault-tolerant operation and maintenance performance is excellent.

[0020] The heat dissipation cabinet 2 integrates a negative pressure fan 21, a positive pressure fan 22, and a circulation pump 23. The input end of the negative pressure fan 21 is connected to the negative pressure interlayer 11 of the prefabricated power distribution cabinet 1, and the output end of the positive pressure fan 22 is connected to the positive pressure interlayer 12. Through the start and stop of the fans and the air volume regulation, the forced convection air cooling circulation of the entire area inside the prefabricated power distribution cabinet 1 is realized.

[0021] Please refer to this first. Figure 3 - Figure 6The battery isolation compartment 13 is equipped with a battery energy storage module 3. The battery energy storage module 3 is composed of multiple sets of spaced energy storage cells 31. Two sets of battery energy storage modules 3 are inserted into each other inside the same battery isolation compartment 13, and the energy storage cells 31 of the two sets of battery energy storage modules 3 are arranged in an alternating manner to make the heat exchange gap of the cells uniform and regular.

[0022] Please refer to this first. Figure 3 The flywheel compartment 14 is equipped with a flywheel energy storage module 4. The whole machine forms a flywheel-electrochemical hybrid energy storage architecture in which the flywheel energy storage module 4 undertakes instantaneous peak loads and the battery energy storage module 3 ensures continuous output. Relying on the millisecond-level attenuation-free high-frequency response characteristics of the flywheel and the long-term stable output advantage of the battery, it can achieve efficient collaborative work in grid frequency regulation and new energy consumption scenarios, effectively reduce the battery charge and discharge rate and frequency, and extend the battery life.

[0023] Please refer to this first. Figure 3 - Figure 6 A serpentine heat exchange channel 6 is arranged between adjacent energy storage cells 31, allowing it to directly contact the heat-generating area of ​​the energy storage cells 31 and absorb working heat. Several equidistant air ducts 61 are formed on the heat exchange channel 6, and a docking air vent 131 is opened inside the battery isolation chamber 13. The docking air vent 131 is interconnected with the corresponding air ducts 61 above and below. The uppermost air duct 61 connects to the input end of the negative pressure interlayer 11, and the lowermost air duct 61 connects to the output end of the positive pressure interlayer 12, thus forming a vertically continuous air-cooled heat exchange channel from the positive pressure interlayer 12, the docking air vent 131, the air ducts 61 to the negative pressure interlayer 11. Strip channels 64 are respectively set on the left and right sides of the air ducts 61 on the heat exchange channel 6. An upper liquid channel 62 is opened on the upper side of the strip channel 64, and a lower liquid channel 63 is opened on the lower side, forming an independent liquid cooling circulation channel. The heat dissipation cabinet 2 houses a liquid cooling circulation module 5, which supplies circulating coolant to the upper and lower liquid channels 62 and 63 of all heat transfer cables 6. A control unit 8 is fixedly installed on one side of the outer wall of the flywheel compartment 14 for intelligent control of the entire machine.

[0024] Furthermore, the number of air ducts 61 is consistent with the number of horizontally arranged battery isolation compartments 13, and the number of heat conduction cables 6 is consistent with the number of vertically arranged battery isolation compartments 13, ensuring that each layer and each row of battery energy storage modules 3 has a dedicated heat dissipation structure, eliminating any dead angles in heat dissipation. Simultaneously, several equidistantly arranged heat dissipation fins 611 are fixed to the inner wall of the air ducts 61, effectively increasing the air-cooled heat exchange contact area, improving normal air-cooled heat dissipation efficiency, and ensuring sufficient heat dissipation and lower energy consumption under both normal and low-temperature operating conditions.

[0025] Please refer to this first. Figure 5The liquid cooling circulation module 5 includes an annular air guide seat 53, on which several spiral liquid storage tanks 51 are mounted. Several heat dissipation fins 52 are fixed to the outer wall of the spiral liquid storage tanks 51, which can passively dissipate heat and cool the coolant inside the tank, improving the stability of the circulating heat exchange. The number of spiral liquid storage tanks 51 is twice the number of heat conduction cables 6, ensuring that each set of heat conduction cables 6 has sufficient coolant reserves and circulation supply capacity to meet the synchronous heat dissipation needs of multiple battery energy storage modules 3.

[0026] Please refer to this first. Figure 9 - Figure 11 The output end of the negative pressure fan 21 is equipped with an upper three-way valve 211, and the output end of the positive pressure fan 22 is equipped with a lower three-way valve 221. The first passage of the upper three-way valve 211 connects to the negative pressure jacket 11, the second passage connects to the top of the liquid cooling circulation module 5, and the third passage connects both the negative pressure jacket 11 and the top of the liquid cooling circulation module 5. The first passage of the lower three-way valve 221 connects to the positive pressure jacket 12, the second passage connects to the bottom of the liquid cooling circulation module 5, and the third passage connects both the positive pressure jacket 12 and the bottom of the liquid cooling circulation module 5. By switching the positions of the upper three-way valve 211 and the lower three-way valve 221, three working modes can be precisely switched: independent air-cooled passage, air-cooled auxiliary liquid cooling heat dissipation passage, and independent liquid cooling passage, adapting to the heat dissipation needs of the entire temperature range.

[0027] Please refer to this first. Figure 12 - Figure 20 A strip-shaped channel 64 is located between the upper liquid channel 62 and the lower liquid channel 63. Two sets of beryllium copper spring plates 65 are symmetrically fixed inside the strip-shaped channel 64. Under normal temperature conditions, the two sets of beryllium copper spring plates 65 have sufficient elasticity and close together to seal the strip-shaped channel 64, separating the upper liquid channel 62 and the lower liquid channel 63 on the same side, realizing independent small-flow circulation of the upper and lower liquid channels. When the equipment heats up and the temperature inside the chamber rises, the elasticity of the beryllium copper spring plates 65 decreases due to heat and they move away from each other. The strip-shaped channel 64 opens, connecting the upper liquid channel 62 and the lower liquid channel 63 on the same side, widening the cross-section of the coolant flow. The beryllium copper spring plate 65 and the inner wall of the strip channel 64 enclose a liquid storage chamber 66, which is filled with a phase change liquid. When heated, the phase change liquid changes from solid to liquid, absorbing a large amount of residual heat and providing a buffer space for the deformation of the beryllium copper spring plate 65. When the temperature drops, the beryllium copper spring plate 65 springs back to its original position and squeezes against each other, causing the phase change liquid to solidify again, providing stable compression support for the spring plate and realizing passive adaptive reciprocating temperature control.

[0028] Please refer to this first. Figures 14-16A flow regulating valve 7 is installed at the end of the heat conductor 6 furthest from the circulating pump 23. The flow regulating valve 7 includes a flow valve chamber 71 fixed to the end of the heat conductor 6. The strip-shaped channel 64, upper liquid channel 62, and lower liquid channel 63 at the end of the heat conductor 6 all extend into the flow valve chamber 71 to ensure complete connection of the passage. A flow valve core 72 is rotatably installed inside the flow valve chamber 71. Symmetrically arranged upper diversion holes 722 and lower diversion holes 723 are provided on one side of the flow valve core 72. A diversion channel 724 is opened inside the valve core to connect the upper diversion holes 722 and lower diversion holes 723 on the same side. The upper diversion holes 722 and lower diversion holes 723 on the same side are aligned and connected to the corresponding upper liquid channel 62 and lower liquid channel 63, respectively. A parallel flow valve groove 721 adapted to the center distance of the two strip-shaped channels 64 is opened on the other side of the flow valve core 72. Under low-temperature conditions, the flow-directing valve core 72, through the upper diversion hole 722 and the lower diversion hole 723, in conjunction with the diversion channel 724, achieves a small-flow independent circulation by connecting the upper liquid channel 62 and the lower liquid channel 63 on the same side, thereby reducing heat dissipation energy consumption. Under high-temperature conditions, the strip channel 64 is fully opened, and the parallel flow valve groove 721 of the flow-directing valve core 72 connects to the two strip channels 64, thereby achieving a large-flow circulation by connecting the two strip channels 64, which greatly improves the liquid cooling heat dissipation efficiency.

[0029] Please refer to this first. Figure 18 - Figure 20 A circulation regulating valve 9 is installed at one end of the heat conduction cable 6 near the circulation pump 23. The circulation regulating valve 9 includes a circulation valve chamber 91 fixed to the end of the heat conduction cable 6. The strip-shaped channel 64, upper liquid channel 62, and lower liquid channel 63 at the end of the heat conduction cable 6 extend into the circulation valve chamber 91. A circulation valve core 92 is rotatably installed inside the circulation valve chamber 91. A return liquid chamber 903 and a supply liquid chamber 904 are respectively formed inside the circulation valve core 92. A return liquid interface 901 communicating with the return liquid chamber 903 is opened at the top, and a supply liquid interface 902 communicating with the supply liquid chamber 904 is opened at the bottom. The circulating valve core 92 has a return liquid upper parallel flow port 921 and a supply liquid lower parallel flow port 922 arranged vertically on one side. The return liquid upper parallel flow port 921 is connected to the return liquid chamber 903 and its width matches the spacing between the two sets of upper liquid channels 62. The supply liquid lower parallel flow port 922 is connected to the supply liquid chamber 904 and its width matches the spacing between the two sets of lower liquid channels 63. The other side has a symmetrical return liquid side valve groove 923 and a supply liquid side valve groove 924. The spacing between the return liquid side valve groove 923 and the supply liquid side valve groove 924 is adapted to the spacing between the two strip channels 64. It can be used in conjunction with the flow direction regulating valve 7 to synchronously switch the loop flow mode and realize graded and precise flow control.

[0030] The input end of the liquid supply port 902 of the circulation regulating valve 9 is connected to the output end of the circulation pump 23, and the input end of the circulation pump 23 is connected to the bottom of the spiral liquid storage tank 51; the output end of the return port 901 is connected to the top of the spiral liquid storage tank 51. The whole system forms a complete closed-loop coolant circulation loop with liquid outlet at the bottom of the spiral liquid storage tank 51, circulation pump 23, liquid supply port 902, heat exchange through the liquid channel of the heat transfer cable 6, return port 901, and liquid return at the top of the spiral liquid storage tank 51. The circulation is well sealed, with no risk of leakage, and the heat exchange operation is stable.

[0031] Both the flow valve core 72 and the circulation valve core 92 are driven to rotate by servo motors. Temperature sensors 132 are installed inside the battery isolation chamber 13 to collect the chamber's temperature. All servo motors, temperature sensors 132, negative pressure fans 21, upper three-way valves 211, positive pressure fans 22, lower three-way valves 221, and circulation pumps 23 are electrically connected to the control unit 8. During operation, temperature sensors 132 collect the chamber's temperature signal in real time and transmit it to the control unit 8. The control unit 8 adaptively adjusts each actuator based on the real-time temperature data, intelligently switching between three operating modes: independent air cooling, combined air-liquid cooling, and independent liquid cooling, achieving seamless adaptive temperature control under all operating conditions.

[0032] This invention can achieve differentiated adaptive heat dissipation control according to different extreme outdoor environmental temperatures, adapting to all outdoor working conditions such as high cold, high temperature, and high altitude. Please refer to this first. Figure 9 Under low-temperature and high-altitude operating conditions, the overall heat generation inside the cabin is low. The control unit 8 adjusts the upper three-way valve 211 and the lower three-way valve 221 to switch to a pure air-cooled independent passage, and the circulation pump 23 goes into hibernation or stands by extremely low power. At this time, the beryllium copper spring plate 65 is closed at room temperature, the strip channel 64 is closed, the upper liquid channel 62 and the lower liquid channel 63 are independently set to a small flow rate, and the flow direction valve core 72 maintains a small flow rate circulation setting. The heat dissipation needs can be met by relying solely on the positive pressure fan 22 and the negative pressure fan 21 to drive the full-area air-cooled circulation, avoiding excessive heat dissipation at low temperatures that could lead to equipment failure, while also significantly reducing the overall energy consumption of the machine.

[0033] Please refer to this first. Figure 10 and Figure 12 Under normal temperature and medium load conditions, i.e., when the temperature is ≤35℃, the battery energy storage module 3 continuously outputs power in a steady state, while the flywheel energy storage module 4 adjusts at low frequency, generating stable residual heat inside the chamber. The control unit 8 switches to a combined air-cooled and liquid-cooled heat dissipation mode, with the air-cooling system continuously engaging in convective heat exchange, and the liquid-cooled circulation module 5 initiating micro-circulation. At this time, the temperature inside the chamber rises slightly, the beryllium copper spring plate 65 deforms slightly, the strip channel 64 opens slightly, and the phase change liquid inside the liquid storage tank 66 undergoes a small phase change to absorb heat, working in conjunction with the air-liquid heat exchange to balance the temperature inside the chamber, eliminating the temperature fluctuation problem of a single heat dissipation mode, ensuring uniform temperature difference of the energy storage cell 31 and stable equipment operation.

[0034] Please refer to this first. Figure 11 and Figure 13 Under extreme conditions of high temperature and heavy load, i.e., temperature > 35℃, the flywheel energy storage module 4 generates pulsed high heat due to high frequency instantaneous charging and discharging, and the battery energy storage module 3 generates a large amount of steady-state heat due to full-load long-term output. After the temperature inside the chamber rises rapidly, the elastic force of the beryllium copper spring plate 65 decreases significantly due to heat, the strip channel 64 is fully opened, connecting the upper liquid channel 62 and the lower liquid channel 63, and the phase change liquid in the liquid storage tank 66 fully absorbs heat through phase change, quickly adsorbing local high-temperature heat; at the same time, the control unit 8 switches to full-load pure liquid cooling mode, the flow direction valve core 72 and the circulation valve core 92 switch to high-flow path, and the circulation pump 23 drives the coolant to circulate in a closed loop at full load. The heat accumulated in the energy storage cell 31 is carried away from all directions by multiple sets of heat conduction tapes 6, and with the all-area air cooling for rapid heat dissipation, the temperature is rapidly reduced, making it suitable for harsh conditions such as desert high temperature and extreme summer high temperature.

[0035] Meanwhile, the modular and split structure of this invention has convenient installation and transportation capabilities as well as fault-tolerant operation and maintenance capabilities. The heat dissipation side cabinet 2 is independently detachable, and the assembly and transportation of the whole unit does not require large hoisting equipment, making it suitable for complex outdoor construction sites. Each heat dissipation circuit and energy storage module is independent of each other. When a single component such as the negative pressure fan 21, positive pressure fan 22, circulation pump 23, flow direction regulating valve 7, circulation regulating valve 9, or single set of heat conduction cable 6 is damaged, the remaining heat dissipation circuits and energy storage units can operate normally and independently without causing the whole unit to shut down. It has strong fault-tolerant operation capabilities, convenient maintenance and replacement, significantly reduces operation and maintenance costs, improves the stability and overall cost-effectiveness of the hybrid energy storage system in grid frequency regulation and new energy consumption scenarios, and has strong adaptability to extreme environments.

[0036] Example 2: This invention also provides an environmental adaptive intelligent control method for outdoor energy storage prefabricated cabins, comprising the following steps: S1. Real-time monitoring: The temperature signal inside the battery isolation compartment 13 is collected in real time by the temperature sensor 132 and transmitted to the control unit 8 in real time. S2, Intelligent Matching: The control unit 8 combines the instantaneous pulse heating characteristics of the flywheel energy storage module 4 with the steady-state continuous heating characteristics of the battery energy storage module 3 to determine the real-time temperature conditions inside the cabin. S3. Coordinated Control: The control unit 8 coordinates the start-stop and gear adjustment of the servo motor, the upper three-position three-way valve 211, the lower three-position three-way valve 221, the negative pressure fan 21, the positive pressure fan 22 and the circulating pump 23, and adaptively switches between three heat dissipation working modes: air cooling, liquid cooling and air-liquid composite. S4. Adaptive flow regulation: While switching the heat dissipation mode, the linkage flow direction regulating valve 7 and circulation regulating valve 9 adaptively adjust the coolant circulation flow to match the real-time heat dissipation requirements and realize intelligent constant temperature control of the prefabricated cabin under all outdoor working conditions.

[0037] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
