[0060] Unless otherwise defined, all technical terms used in the embodiments of this utility model have the same meaning as commonly understood by those skilled in the art.

[0061] To make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings. Figure 1

[0062] Combination Figure 2 As shown, this embodiment provides a heat recovery system, which includes: a heat generation component 1 and a heat recovery component 2;

[0063] The outlet of the heat energy generating component 1 is connected to the inlet of the heat energy recovery component 2; the first outlet of the heat energy recovery component 2 is connected to the outlet of the heat energy recovery component 2, and the second outlet of the heat energy recovery component 2 is connected to at least one electrical outlet 33, which is used to output the system working electrical energy converted from the working heat energy of the component.

[0064] The heat generation component 1 includes at least one of a battery component and an electrical component. The heat generation component 1 is used to generate working heat energy of the component during operation. The heat recovery component 2 is used to collect the working heat energy of the component and convert it into working electrical energy of the system.

[0065] Indicatively, at least one power outlet 33 corresponds one-to-one with at least one power quality level. The power quality level is used to characterize the quality level of the system's working power energy converted from the working heat energy of the component. The working heat energy of the component is the energy that causes the temperature of the heat-generating component to rise during operation.

[0066] In this embodiment, the heat recovery system may generate working heat energy that causes the temperature of the heat generating component 1 to rise during operation.

[0067] When the component generates working heat, the heat energy recovery component 2 collects the working heat generated by the heat energy generating component 1 during operation, which causes the temperature of the heat energy generating component to rise, and converts the working heat energy of the component into the working electrical energy of the system, so as to realize the conversion of heat energy into electrical energy.

[0068] Combination Figure 3 As shown, this embodiment provides a heat recovery system, which includes a heat generation component 1 and a heat recovery component 2. The heat recovery component 2 includes an expander 3 and a plate heat exchanger 4.

[0069] The outlet of the heat generating component 1 is connected to the first inlet of the plate heat exchanger 4, the first outlet of the plate heat exchanger 4 is connected to the inlet of the expander 3, the first outlet of the expander 3 is connected to the second inlet of the plate heat exchanger 4, the second outlet of the plate heat exchanger 4 is connected to the inlet of the heat generating component 1, and the second outlet of the expander 3 is connected to at least one electrical outlet 33.

[0070] Optionally, the second outlet of the plate heat exchanger is connected to the heat generation component, and at least one electrical outlet 33 corresponds one-to-one with at least one electrical quality level. The electrical quality level is used to characterize the quality level of the system working electrical energy converted from the working heat energy of the component. The working heat energy of the component is the energy that causes the temperature of the heat generation component to rise during operation.

[0071] In this embodiment, the heat recovery system may generate working heat energy that causes the temperature of the heat generating component 1 to rise during operation.

[0072] When the component generates working heat energy, the component working heat energy is collected by plate heat exchanger 4, and the component working heat energy collected by plate heat exchanger 4 causes the expander 3 to do mechanical work, thereby converting the component working heat energy into system working electrical energy, so as to realize the conversion of heat energy into electrical energy.

[0073] In the heat recovery process, a thermodynamic circulation loop exists between the plate heat exchanger 4 and the expander 3. This loop transfers and converts heat energy through the flow of a medium. When the medium flows through the expander 3, it transfers its internal energy (including the working heat energy of the components) to the expander 3, causing it to perform mechanical work and lowering the medium's temperature. The cooled medium then continues to circulate through the plate heat exchanger 4, further absorbing the working heat energy of the subsequent components. Thus, energy transfer and conversion can be achieved through the corresponding physical processes of each component within the thermodynamic circulation loop.

[0074] The expander 3 is connected to at least one power outlet 33, and each power outlet 33 corresponds to a power quality level. Therefore, different power outlets 33 can correspond to different power quality levels. The power quality level is used to characterize the quality level of the system's working electrical energy converted from the working heat energy of the component. By using at least one power outlet 33, the system's working electrical energy obtained from the mechanical work of the expander is enriched, so as to adapt to more diverse and flexible electrical energy application scenarios.

[0075] Schematic illustration: Each power outlet 33 is connected to at least one device, which includes a first device operating a heat-generating component 1, such as a battery component or a mobile phone with the battery component deployed in the first device. Power of a corresponding power quality level output through the power outlet 33 enables the device connected to the power outlet 33 to operate. Connecting devices with high power demand to power outlets 33 with higher power quality levels provides a more stable power supply for these devices; connecting devices with low power demand to power outlets 33 with lower power quality levels provides a more efficient power supply for these devices, improving energy recovery and utilization rates, and enhancing power supply flexibility.

[0076] Combination Figure 4As shown, this embodiment provides a heat recovery system, which includes a heat generation component 1 and a heat recovery component 2; the heat recovery component 2 includes a plate heat exchanger 4, a first condenser 5, an evaporator 6 and an expander 3.

[0077] The outlet of the heat generating component 1 is connected to the first inlet of the plate heat exchanger 4. The first outlet of the plate heat exchanger 4 is connected to the first inlet of the first condenser 5. The first outlet of the first condenser 5 is connected to the first inlet of the evaporator 6. The first outlet of the evaporator 6 is connected to the inlet of the expander 3. The outlet of the expander 3 is connected to the second inlet of the evaporator 6. The second outlet of the evaporator 6 is connected to the second inlet of the first condenser 5. The second outlet of the first condenser 5 is connected to the second inlet of the plate heat exchanger 4. The circuit formed by the heat generating component 1 and the plate heat exchanger 4 is filled with a heat transfer medium. The circuit formed by the first condenser 5 and the plate heat exchanger 4 is filled with a refrigerant medium.

[0078] The expander 3 is connected to at least one power outlet 33, which is connected to at least one device. The at least one device includes a first device that operates the heat-generating component 1. The at least one power outlet 33 is used to output the system working power converted from the working heat energy of the component.

[0079] Optionally, the second outlet of the plate heat exchanger is connected to the heat generation component, and at least one electrical outlet 33 corresponds one-to-one with at least one electrical quality level. The electrical quality level is used to characterize the quality level of the system working electrical energy converted from the working heat energy of the component. The working heat energy of the component is the energy that causes the temperature of the heat generation component to rise during operation.

[0080] In this embodiment, the heat recovery system may generate working heat energy that causes the temperature of the heat generating component 1 to rise during operation.

[0081] When the component generates operating heat, the plate heat exchanger 4 collects the operating heat and transfers it to the first condenser 5, which releases the operating heat. Due to the connection between the evaporator 6 and the first condenser 5, the operating heat released by the first condenser 5 is absorbed by the evaporator 6.

[0082] After absorbing the working heat energy of the components, the evaporator 6 causes the expander 3 to do mechanical work, thereby converting the working heat energy of the components into the working electrical energy of the system, so as to realize the conversion of heat energy into electrical energy.

[0083] In the heat recovery process, the first condenser 5, evaporator 6, and expander 3 form a thermodynamic cycle. Heat energy is transferred and converted through the flow of a medium within this cycle. When the medium flows through expander 3, its internal energy (including the heat energy from component operation) causes expander 3 to perform mechanical work, thus lowering the medium's temperature. The cooled medium continues to flow through evaporator 6 and the first condenser 5, further absorbing the heat energy from subsequent component operation. Therefore, energy transfer and conversion are achieved through the corresponding physical processes of each component within the thermodynamic cycle.

[0084] The expander 3 is connected to at least one power outlet 33, and each power outlet 33 corresponds to a power quality level. Therefore, different power outlets 33 can correspond to different power quality levels. The power quality level is used to characterize the quality level of the system's working electrical energy converted from the working heat energy of the component. By using at least one power outlet 33, the system's working electrical energy obtained from the mechanical work of the expander is enriched, so as to adapt to more diverse and flexible electrical energy application scenarios.

[0085] Schematic illustration: Each power outlet 33 is connected to at least one device, which includes a first device operating a heat-generating component 1, such as a battery component or a mobile phone with the battery component deployed in the first device. Power of a corresponding power quality level output through the power outlet 33 enables the device connected to the power outlet 33 to operate. Connecting devices with high power demand to power outlets 33 with higher power quality levels provides a more stable power supply for these devices; connecting devices with low power demand to power outlets 33 with lower power quality levels provides a more efficient power supply for these devices, improving energy recovery and utilization rates, and enhancing power supply flexibility.

[0086] In an alternative embodiment, the plate heat exchanger includes a first heat exchange channel and a second heat exchange channel separated by heat exchange plates.

[0087] The inlet of the first heat exchange channel is connected to the inlet of the heat generation component 1, and the outlet of the first heat exchange channel is connected to the inlet of the heat generation component 1; the outlet of the second heat exchange channel is connected to the first inlet of the first condenser 5, and the inlet of the second heat exchange channel is connected to the second outlet of the first condenser 5.

[0088] Schematic diagram: the inlet of the first heat exchange channel is the first inlet of the plate heat exchanger, and the outlet of the first heat exchange channel is the second outlet of the plate heat exchanger; the outlet of the second heat exchange channel is the first outlet of the plate heat exchanger, and the inlet of the second heat exchange channel is the second inlet of the plate heat exchanger.

[0089] The first heat recovery loop, formed by the heat generation component 1 and the first heat exchange channel, is filled with a heat transfer medium; the second heat recovery loop, formed by the second heat exchange channel and the first condenser 5, is filled with a refrigerant medium; heat exchange occurs between the heat transfer medium flowing through the first heat exchange channel and the refrigerant medium flowing through the second heat exchange channel.

[0090] Indicatively, a plate heat exchanger is a component used for energy exchange in heat exchange. In a plate heat exchanger, at least two different media flow through it. The different media are separated by heat exchange plates, that is, the heat exchange plates separate the different media to obtain different channels. The media in the different channels flow in parallel and achieve heat exchange through the heat exchange plates. Typically, heat energy is transferred on the surface of the heat exchange plates.

[0091] Optionally, at least two different media include a heat transfer medium and a cooling medium, with the heat transfer medium flowing through a first heat exchange channel and the cooling medium flowing through a second heat exchange channel.

[0092] A heat transfer medium is a substance used to store and transfer heat energy during heat exchange, helping to achieve efficient energy utilization. Examples of heat transfer media include antifreeze, water, oil, and salt solutions.

[0093] Refrigerants are typically liquids or gases used to absorb or release heat energy during heat exchange. For example, in a refrigeration system, the refrigerant absorbs heat energy through evaporation and releases it during condensation. Examples of refrigerants include gaseous refrigerants (Freon, ammonia, carbon dioxide) and liquid refrigerants.

[0094] In a schematic manner, the heat generation component 1, which generates working heat during operation, together with the first heat exchange channel forms a first heat recovery loop, which is filled with a heat transfer medium. Therefore, the heat transfer medium can transfer the working heat generated by the heat generation component to the first heat exchange channel of the plate heat exchanger through the first heat recovery loop.

[0095] Because the heat transfer medium flowing through the first heat exchange channel in the plate heat exchanger exchanges heat energy with the refrigeration medium flowing through the second heat exchange channel, after the energy storage system transfers the working heat energy of the components to the first heat exchange channel, the heat exchange plate transfers the working heat energy of the components carried by the heat transfer medium in the first heat exchange channel to the refrigeration medium in the second heat exchange channel. This causes the temperature of the heat transfer medium in the first heat exchange channel to decrease and the temperature of the refrigeration medium in the second heat exchange channel to increase, thus achieving the purpose of transferring the working heat energy of the components to the second heat exchange channel.

[0096] Indicatively, the second heat exchange channel and the first condenser 5 form a second heat recovery loop, which is filled with a refrigerant. Therefore, the refrigerant flows from the second heat exchange channel through the second heat recovery loop to the first condenser 5, thereby transferring the working heat energy absorbed from the second heat exchange channel to the first condenser 5 through the second heat recovery loop.

[0097] In an optional embodiment, such as Figure 1 As shown, with Figure 5 Based on this, the heat recovery system also includes: a compressor 7, a four-way solenoid valve 8, and the heat recovery component 2 includes a plate heat exchanger 4 and a first condenser 5.

[0098] The discharge port 71 of the compressor 7 is connected to the first valve end 81 of the four-way solenoid valve 8; the suction port 72 of the compressor 7 is connected to the second valve end 82 of the four-way solenoid valve 8; the third valve end 83 of the four-way solenoid valve 8 is connected to the first inlet of the first condenser 5; and the first outlet of the plate heat exchanger 4 is connected to the fourth valve end 84 of the four-way solenoid valve 8.

[0099] Indicatively, compressor 7 is a device responsible for compressing low-pressure, low-temperature refrigerant (such as Freon, ammonia, etc.; refrigerant can also be called a coolant) into high-pressure, high-temperature gas; this process is an important step in the thermodynamic cycle, and compressor 7 provides the necessary energy for the subsequent condensation process by increasing the pressure and temperature of the refrigerant.

[0100] Indicatively, the four-way solenoid valve 8 is a valve used to change the flow direction of the refrigerant. Its working principle is to reverse the cooling and heating modes by changing the direction of the refrigerant flow. The four-way solenoid valve 8 is typically controlled by an electromagnetic coil, enabling it to change the airflow direction and adapt to different operating conditions.

[0101] The first valve end 81 and the third valve end 83 form the first passage of the four-way solenoid valve 8.

[0102] Therefore, the compressor 7 compresses the low-pressure, low-temperature refrigerant into a high-temperature, high-pressure gas (such as a high-temperature gaseous refrigerant, i.e., a high-temperature gaseous refrigerant) through the exhaust port; based on the first passage of the four-way solenoid valve 8 formed by the first valve end 81 and the third valve end 83, and the third valve end 83 being connected to the first inlet of the first condenser 5, the high-temperature gaseous refrigerant can be sent into the first condenser 5 through the first passage.

[0103] The second valve end 82 and the fourth valve end 84 form the second passage of the four-way solenoid valve 8. The first passage and the second passage determine the flow of the refrigerant, that is, the first passage and the second passage characterize the function of the four-way solenoid valve 8.

[0104] Since the first outlet of the plate heat exchanger 4 is connected to the fourth valve end 84 of the four-way solenoid valve 8, and the first outlet of the plate heat exchanger 4 represents the outlet of the second heat exchange channel, the fourth valve end 84 of the four-way solenoid valve 8 will receive the refrigerant carrying the working heat energy of the component transferred by the second heat exchange channel based on the flow process of the refrigerant. In addition, based on the second passage formed by the second valve end 82 and the fourth valve end 84, and the connection between the second valve end 82 and the suction port 72 of the compressor 7, the refrigerant flows from the fourth valve end 84 through the second valve end 82 to the compressor 7 (in gaseous or liquid form).

[0105] Considering that the work done by the compressor 7 is a cyclic process, the heat energy collected by the plate heat exchanger 4 flows into the compressor 7 through the refrigerant, so as to improve the energy level and realize energy cycle through the work done by the compressor 7. The collected heat energy is not directly released to be wasted, but participates in the thermodynamic cycle process based on the compressor's work and the collection of heat energy from the components to achieve more efficient energy utilization and improve energy efficiency.

[0106] In an optional embodiment, such as Figure 6 As shown, the heat recovery system also includes a fan 9; the heat recovery component 2 includes a first condenser 5 and an evaporator 6; a heat collection channel is established between the first outlet of the first condenser 5 and the first inlet of the evaporator 6; the fan 9 transfers the heat energy collected by the refrigerant flowing through the first condenser 5 to the evaporator 6 through the heat collection channel.

[0107] Schematic diagram: The refrigerant forms a circulating flow loop between the second heat exchange channel of the plate heat exchanger 4, the compressor, the four-way solenoid valve, and the condenser. The second heat exchange channel collects the working heat energy of the components transferred by the first heat exchange channel. When the compressor 7 is working, the refrigerant flowing through the first condenser 5 also includes the energy generated by the work done by the compressor 7. Therefore, the heat energy collected by the refrigerant flowing through the first condenser 5 includes the energy generated by the work done by the compressor 7 and the collected working heat energy of the components.

[0108] Optionally, the refrigerant temperature at the outlet of the first condenser 5 is usually higher (e.g., 40-60°C), while the refrigerant temperature at the inlet of the evaporator 6 is usually lower (e.g., 5-15°C); a capillary tube is provided between the first condenser 5 and the evaporator 6 as a heat collection channel, thereby reducing the refrigerant pressure and temperature.

[0109] Furthermore, to facilitate efficient heat exchange, fan 9 guides the cooling air from the first condenser 5 to the evaporator 6, allowing the evaporator 6 to collect the heat energy from the refrigerant flowing through the first condenser 5. Considering the involvement of the compressor 7, the heat energy collected by the evaporator 6 includes the operating heat energy and working energy generated by the aforementioned heat-generating component 1, which are typically expressed as heat energy in the refrigerant.

[0110] In an optional embodiment, such as Figure 7 As shown, the heat recovery system also includes a second condenser 10 and a working fluid pump 11; the heat recovery component 2 also includes a first condenser 5, an evaporator 6 and an expander 3; the outlet of the expander 3 is connected to the inlet of the second condenser 10, the outlet of the second condenser 10 is connected to the inlet of the working fluid pump 11, and the outlet of the working fluid pump 11 is connected to the second inlet of the evaporator 6; a heat transfer medium flows in the third heat recovery loop formed by the evaporator 6, the expander 3, the second condenser 10 and the working fluid pump 11.

[0111] Schematic illustration: the third heat recovery loop formed by evaporator 6, expander 3, second condenser 10, and working fluid pump 11 can also be called an Organic Rankine Cycle power generation system. The heat transfer medium is the medium that transfers heat energy, typically implemented as an organic working fluid. The working fluid has a relatively low boiling point and good thermodynamic properties, enabling it to efficiently convert heat energy at relatively low heat source temperatures. Heat transfer media include hydrocarbon compounds, fluorinated hydrocarbons, ketone compounds, water-glycol solutions, etc., and are not limited here.

[0112] In this process, after the expander 3 converts the heat energy in the heat transfer medium into electrical energy, the temperature of the heat transfer medium decreases and it flows through the second condenser 10. That is, the temperature of the heat transfer medium flowing through the second condenser 10 is lower than the temperature of the heat transfer medium flowing through the expander 3.

[0113] Subsequently, the second condenser 10 further reduces the temperature of the heat transfer medium flowing through it, such as obtaining a low-temperature liquid working fluid (i.e., a liquid heat transfer medium after the temperature has been reduced); then, the condensed low-pressure liquid working fluid is pressurized by the working fluid pump 11 and pushed to the evaporator 6, thereby maintaining the circulation of the working fluid in the third heat recovery loop and providing sufficient pressure for the next step of heat absorption and evaporation.

[0114] In an optional embodiment, the heat recovery system further includes a generator; the expander 3 is connected to the generator via a mechanical shaft; the generator includes at least one electrical outlet 33.

[0115] Indicatively, the evaporator 6 increases the temperature of the heat transfer medium based on the received heat energy (e.g., vaporizes into a high-temperature gaseous working fluid). The evaporator 6 then transfers the high-temperature heat transfer medium to the expander 3. Due to the expansion process of the high-temperature gaseous working fluid, the expander 3 performs work and drives the generator to generate electricity through the mechanical shaft.

[0116] The working principle of the expander 3 is that when the working medium (i.e., the heat transfer medium) expands, it releases energy, which is transferred through the mechanical motion of the expander. The expander converts the thermal energy of the working medium into mechanical energy; the generator is the key device that converts the mechanical energy provided by the expander into electrical energy. It is connected to the expander through a mechanical shaft and uses the rotational power provided by the expander to generate electrical energy.

[0117] Optionally, the generator includes at least one power outlet 33, each power outlet 33 delivering generated power of different power quality levels to external devices (loads, etc.), or inputting it into the power grid to provide power.

[0118] In an optional embodiment, such as Figure 8 As shown, the heat recovery system also includes a first three-way component 12, a second three-way component 13, a first three-way solenoid valve 14, and a first one-way valve 15; the heat recovery component 2 includes an expander 3, a plate heat exchanger 4, and a first condenser 5.

[0119] The first component end 121 of the first three-way component 12 is connected to the second outlet of the first condenser 5; the second component end 122 of the first three-way component 12 is connected to the first valve end of the first three-way solenoid valve 14; and the third component end 123 of the first three-way component 12 is connected to the inlet of the first one-way valve 15.

[0136] In an optional embodiment, such as Figure 1 to Figure 9 As shown, taking the application of a heat recovery system to heat recovery in an energy storage system as an example, the heat generation component 1 in the heat recovery system, which generates the working heat of the components, includes an electrical component 102; the electrical component 102 is a component in the energy storage system used to store electrical energy.

[0137] The second outlet of the plate heat exchanger 4 is connected to the inlet of the electrical component 102, and the outlet of the electrical component 102 is connected to the first inlet of the plate heat exchanger 4.

[0138] Indicatively, electrical component 102 transfers heat energy to plate heat exchanger 4 through an outlet; plate heat exchanger 4 transfers the working heat energy of the component through a heat exchange process.

[0139] Optionally, a heat transfer medium flows between the electrical component 102 and the plate heat exchanger 4. The heat transfer medium transfers heat energy to the plate heat exchanger 4 through the outlet of the electrical component 102. The plate heat exchanger 4 transfers the working heat energy of the component to the cooling medium through the heat exchange process and discharges the cooling medium from the second outlet of the plate heat exchanger 4.

[0140] In some embodiments, the system further includes: a third three-way solenoid valve 22, a high-pressure box 28, a manifold 29, and a second flow switch 31.

[0141] The second outlet of the plate heat exchanger 4 is connected to the first valve end of the third three-way solenoid valve 22, the second valve end of the third three-way solenoid valve 22 is connected to the first inlet of the plate heat exchanger 4, and the third valve end of the third three-way solenoid valve 22 is connected to the inlet of the high-pressure box 28; the outlet of the high-pressure box 28 is connected to the inlet of the electrical component 102; the outlet of the electrical component 102 is connected to the inlet of the manifold 29, and the outlet of the manifold 29 is connected to the inlet of the second water pump 30; the outlet of the second water pump 30 is connected to the inlet of the second flow switch 31, and the outlet of the second flow switch 31 is connected to the first inlet of the plate heat exchanger 4.

[0142] In some embodiments, the system further includes: a fourth three-way solenoid valve 27; the first valve end of the fourth three-way solenoid valve 27 is connected to the first inlet of the plate heat exchanger 4; the second valve end of the fourth three-way solenoid valve 27 is connected to the second valve end of the third three-way solenoid valve 22; and the third valve end of the fourth three-way solenoid valve 27 is connected to the outlet of the second flow switch 31.

[0143] In an optional embodiment, taking the application of the heat recovery system to the heat recovery of the energy storage system as an example, if the heat energy generating component 1 used to generate the working heat energy of the component in the heat recovery system includes a battery component 101 and an electrical component 102, the purpose of flexibly collecting the working energy of the component can be achieved through the third three-way solenoid valve 22.

[0144] In combination with the above Figure 10 Get as ​ The diagram shown illustrates the overall architecture and operation flow of the heat recovery system. Once the heat recovery system is started, the operation flow is as follows.

[0145] (1) Battery thermal management flow path: Third three-way solenoid valve 22 (ab) → low temperature antifreeze → battery component 101 → high temperature antifreeze → water tank 23 → first water pump 24 → first flow switch 25 → positive temperature coefficient (PTC) element 26 (not open) → fourth three-way solenoid valve 27 (ba) → plate heat exchanger 4 → low temperature antifreeze → third three-way solenoid valve 22 (ab).

[0146] The water tank 23 is used to store antifreeze and other coolants (i.e., heat transfer medium) and to provide a liquid source for the heat recovery system, ensuring that there is enough heat transfer medium for flow and heat exchange in the heat recovery system.

[0147] The first water pump 24 is used to extract the heat transfer medium from the water tank 23 and send it to downstream components through pipelines. The water pump circulates the liquid, maintaining the circulation of the heat transfer medium and ensuring the normal operation of the heat recovery system.

[0148] The first flow switch 25 detects the flow status of the heat transfer medium. When the heat transfer medium flows through the first flow switch 25, the first flow switch 25 monitors the flow rate to ensure that the heat transfer medium flows at a predetermined flow rate. If the flow rate is too low (which may mean that the first water pump 24 has malfunctioned or the pipeline is blocked), the first flow switch 25 will trigger an alarm or cut off the system circuit to prevent damage to the heat recovery system.

[0149] The positive temperature coefficient (PTC) element 26 is a temperature-sensitive element whose resistance increases with increasing temperature. When off, the PTC element 26 has a high resistance. When the temperature exceeds a set threshold, the resistance of the PTC element 26 increases rapidly, limiting current flow and providing temperature protection to prevent overheating damage to the heat recovery system.

[0150] Both the third three-way solenoid valve 22 and the fourth three-way solenoid valve 27 are three-way solenoid valves used to control the flow direction of the heat transfer medium. They can typically switch between different flow paths or operating modes. When a three-way solenoid valve receives a control signal, it opens or closes different channels, thereby changing the flow path of the heat transfer medium to regulate the system temperature or start / stop a certain cycle.

[0151] In the third three-way solenoid valve 22, end a represents the first valve end, end b represents the second valve end, and end c represents the third valve end; in the fourth three-way solenoid valve 27, end a represents the first valve end, end b represents the second valve end, and end c represents the third valve end.

[0152] That is: the low-temperature antifreeze (a heat transfer medium with a lower temperature) carries away the working heat energy of the battery component 101 and becomes high-temperature antifreeze (a heat transfer medium with a higher temperature, which absorbs the working heat energy released by the battery component 101); then the high-temperature antifreeze flows through the plate heat exchanger 4 and carries away the working heat energy of the component, thus becoming low-temperature antifreeze.

[0153] (2) Thermal management flow path of electrical components: Third three-way solenoid valve 22(ac) → low temperature antifreeze → high pressure box 28 → electrical component 102 → junction box 29 → second water pump 30 → second flow switch 31 → fourth three-way solenoid valve 27(ca) → plate heat exchanger 4 → low temperature antifreeze → third three-way solenoid valve 22(ac).

[0154] The high-pressure box 28 is a container for storing or managing high-pressure liquids or gases. The manifold 29 is used for centralized management of the heat transfer medium flowing through it. The second water pump 30 is used to extract the heat transfer medium from the manifold 29 and send it to downstream components through pipelines.

[0155] The second flow switch 31 detects the flow state of the heat transfer medium; when the heat transfer medium flows through the second flow switch 31, the second flow switch 31 monitors the flow rate to ensure that the heat transfer medium flows at a predetermined flow rate.

[0156] The third three-way solenoid valve 22 has end a representing the first valve end, end b representing the second valve end, and end c representing the third valve end; the circuit formed by ends a and b is used to dissipate heat from the battery component 101; the circuit formed by ends a and c is used to dissipate heat from the electrical component 102.

[0157] The fourth three-way solenoid valve 27 has end a representing the first valve end, end b representing the second valve end, and end c representing the third valve end; the circuit formed by ends a and b is used to dissipate heat from the battery component 101; the circuit formed by ends a and c is used to dissipate heat from the electrical component 102.

[0158] That is: the low-temperature antifreeze (a heat transfer medium with a lower temperature) carries away the working heat energy of the electrical component 102 and becomes high-temperature antifreeze (a heat transfer medium with a higher temperature, which absorbs the working heat energy of the electrical component 102); then the high-temperature antifreeze flows through the plate heat exchanger 4 and carries away the working heat energy of the component, thus becoming low-temperature antifreeze.

[0159] (3) Refrigerant flow path: Compressor 7 → High temperature gaseous refrigerant → Four-way solenoid valve 8 (ac) → First condenser 5 → Medium temperature liquid refrigerant → First three-way solenoid valve 14 → First check valve 15 → Second three-way solenoid valve 18 → Liquid receiver 20 → Expansion valve 21 → Low temperature gas-liquid two-state refrigerant → First three-way solenoid valve 14 → Second check valve 16 → Second three-way solenoid valve 18 → Plate heat exchanger 4 → Low temperature gaseous refrigerant → Four-way solenoid valve 8 (db) → Compressor.

[0160] The liquid storage tank 20 is a container used to store and maintain liquid media (such as coolant, antifreeze, refrigerant, etc.), which can help the heat recovery system maintain a certain liquid volume during operation and regulate the liquid changes in the system.

[0161] An expansion valve 21 is a device used to regulate the flow rate of liquids, commonly used in refrigeration systems, air conditioning systems, and certain heat exchange systems. The expansion valve 21 is typically located at the outlet of the liquid refrigerant and can precisely control the flow rate and temperature of the refrigerant.

[0162] That is: the compressor 7 compresses the refrigerant (refrigeration medium) into a high-temperature gaseous form, and then flows through the four-way solenoid valve 8 to the first condenser 5 to cool down and transform into a medium-temperature liquid refrigerant (the refrigerant in a liquid form with a lower temperature after liquefaction); then it flows through the first three-way solenoid valve 14, the first one-way valve 15, the second three-way solenoid valve 18, the liquid receiver 20, and the expansion valve 21 to transform into a low-temperature gas-liquid dual-state refrigerant (a refrigerant in both low-temperature gaseous and liquid forms); then it absorbs the working heat energy of the components through the plate heat exchanger 4 and obtains a low-temperature gaseous refrigerant.

[0163] (4) ORC power generation system flow path: low temperature liquid working fluid → working fluid pump 11 → evaporator 6 → high temperature gaseous working fluid → expander 3 → low temperature gaseous working fluid → second condenser 10 → low temperature liquid working fluid.

[0164] That is, the low-temperature liquid working fluid absorbs heat through the working fluid pump 11 and the evaporator 6 to obtain a high-temperature gaseous working fluid (thermal energy conversion medium), and then does work through the expander 3 to obtain a low-temperature gaseous working fluid, and then cools down through the second condenser 10 to obtain a low-temperature liquid working fluid (a working fluid in a liquid form with a lower temperature).

[0165] Indicatively, when the battery component 101 is in cooling mode, the above-mentioned flow paths (1), (3), and (4) are run. The waste heat of the battery is transferred to the plate heat exchanger 4 through the antifreeze. The heat energy of the plate heat exchanger 4 is then transferred to the first condenser 5 through the refrigerant. The heat energy of the first condenser 5 is further transferred to the expander 3 through the evaporator 6. The mechanical work of the expander 3 is converted into electrical energy.

[0166] When the electrical component 102 is in cooling mode, the above-mentioned flow paths (2), (3), and (4) are run. The waste heat of the electrical component 102 is transferred to the plate heat exchanger 4 through the antifreeze. The heat energy of the plate heat exchanger 4 is then transferred to the first condenser 5 through the refrigerant. The heat energy of the first condenser 5 is further transferred to the expander 3 through the evaporator 6. The mechanical work of the expander 3 is converted into electrical energy.

[0167] Through the energy management mode of the above-mentioned heat recovery system, on the one hand, the battery component 101 and electrical component 102 are cooled, and on the other hand, the waste heat generated by the battery component 101 and electrical component 102 is recovered and managed.

[0168] In an optional embodiment, when any one of the following three cooling modes is reached, the above-mentioned heat recovery system is activated to achieve the purpose of recovering the working heat energy of the system components in the energy storage system.

[0169] 1. Acquire real-time data of battery temperature and battery state of charge (SOC) of the energy storage system, and when the real-time data of battery temperature and SOC meet the preset battery cooling strategy, determine to start the corresponding battery cooling mode to achieve battery cooling.

[0170] 2. Acquire real-time data on battery temperature and battery temperature rise rate of the energy storage system. When the real-time data on battery temperature and battery temperature rise rate meet the preset threshold, determine to activate the battery thermal runaway rapid cooling mode. At this time, the control system operates at full load to achieve the most powerful battery cooling.

[0171] 3. Obtain real-time temperature data of electrical components in the energy storage system, and when the real-time temperature data of electrical components meets the preset threshold, determine to activate the corresponding electrical component cooling mode, thereby achieving cooling of the electrical components.

[0172] It is worth noting that the above are merely illustrative examples, and the embodiments of this application are not limited thereto.

[0173] In summary, by using a heat recovery system, energy waste is avoided by directly releasing the working heat of components into the external environment. At the same time, by recovering the working heat of components and converting it into the working electrical energy of the system, the system can supply the working electrical energy to at least one device through at least one electrical outlet to achieve the purpose of electrical energy utilization. This enables flexible conversion and coordinated control between heat energy and electrical energy, thereby improving energy utilization efficiency.

[0174] In an optional embodiment, the above-mentioned heat recovery system is applied to the energy utilization scenario during the operation of the energy storage system. The energy storage system includes multiple system components. During the operation of the energy storage system, the system components act as heat generation components that generate the working heat energy of the components. Based on the component operation data of the system components, it is determined whether to run the above-mentioned heat recovery system to recover the working heat energy of the components. The recovery of the working heat energy of the components includes the following steps.

[0175] 1. Obtain component operation data of system components in the energy storage system, including at least one of battery components and electrical components.

[0176] As an illustration, an energy storage system, as a complex integrated system, is typically composed of multiple system components. System components are the parts that make up a complex energy storage system; among them, system components include at least one of battery components and electrical components.

[0177] To illustrate, battery components are the core energy storage units in an energy storage system, responsible for directly storing and releasing electrical energy, such as battery cells, battery modules, and battery clusters.

[0178] Illustratively, electrical components are the parts of an energy storage system related to the conversion, transmission, and control of electrical energy, such as converters, transformers, switchgear, distribution cabinets, detection and communication components, etc.

[0179] Optionally, the component operation data includes battery operation data corresponding to the battery component, and the battery operation data includes at least one of various data such as battery temperature data, battery energy data, battery capacity data, and battery running time data.

[0180] This is illustrative of the operational data of electrical components. The operational data of electrical components can be obtained through specialized electrical detection components and / or sensors, such as detecting the temperature of electrical components through temperature sensors to obtain electrical component temperature data, and detecting the power distribution through current and voltage sensors to obtain power distribution data, etc. There are no limitations here.

[0181] 2. If the component operating data meets the heat recovery conditions, obtain the component operating heat energy corresponding to the system component in the energy storage system.

[0182] When at least one system component in an energy storage system generates component operating heat energy, the component operating heat energy generated by at least one system component is collected as the system operating heat energy.

[0183] Indicatively, heat recovery conditions are used to measure whether heat energy is recovered during the operation of an energy storage system. After collecting the component operation data corresponding to the battery components in the energy storage system, the component operation data is compared with the heat recovery conditions. If the component operation data meets the heat recovery conditions, it is considered that the heat energy generated during the operation of the energy storage system needs to be recovered, that is, the system working heat energy corresponding to the energy storage system is obtained.

[0184] Among them, component operating heat energy is the energy that causes the temperature of system components to rise during the operation of the energy storage system. Illustratively, during the operation of an energy storage system, in addition to converting electrical energy into at least one of the forms of energy such as kinetic energy, mechanical energy, chemical energy, and pressure energy, some electrical energy may also be converted into heat energy. For example, during charging and discharging, some electrical energy may be converted into heat energy due to chemical reactions or current flow; furthermore, overcharging and discharging or excessively high ambient temperatures may also cause the energy storage system to generate a large amount of heat energy, even leading to high battery temperatures.

[0185] 3. Convert the system's thermal energy into system electrical energy of at least one power quality level, which is used to provide power for the operation of at least one device, including a first device that operates an energy storage system.

[0186] In a illustrative way, compared to directly releasing the heat energy of components into the external environment, the heat energy of components is recovered and converted into electrical energy for system operation, thus achieving the goal of recycling electrical energy-heat energy-electricity energy.

[0187] Optionally, the heat recovery system described above can be used to recover the heat generated by the system components during the operation of the energy storage system, so as to obtain the system's operating electrical energy.

[0188] In some embodiments, when converting the thermal energy of a component into electrical energy of the system, the thermal energy of the component is converted into electrical energy of the system with at least one power quality level; that is, when converting electrical energy of the system with multiple power quality levels, it is possible to obtain electrical energy of high power quality level and electrical energy of low power quality level, so as to adapt to different power application scenarios through different power quality levels.

[0189] The system operating power is used to provide power for the operation of at least one device.

[0190] In illustrative terms, the system's operating electrical energy, converted from the heat energy recovered from the component's operation, can provide power for the operation of at least one device, such as charging a small mobile device using the converted system operating electrical energy; and / or, store the converted system operating electrical energy to meet the subsequent possible power needs of at least one device (such as using system operating electrical energy during power outages), etc.

[0191] Optionally, when multiple power quality levels are obtained, corresponding to different system operating power, different utilization methods are adopted for the system operating power of different power quality levels. For example, high power quality level system operating power can be used to provide power to equipment 1 with a higher equipment level (such as security equipment, emergency equipment, etc.), while low power quality level system operating power can be used to provide power to equipment 2 with a lower equipment level (such as small mobile devices, etc.), thereby quantifying the use of different power quality levels and improving power utilization efficiency and power supply stability.

[0192] At least one of the devices includes a first device for operating an energy storage system.

[0193] In illustrative terms, the operation of an energy storage system typically depends on the equipment that deploys the energy storage system. The equipment that operates the energy storage system is referred to as the first equipment. For example, the first equipment is an electric vehicle, and the energy storage system is an electric vehicle battery; or, the first equipment is a mobile phone terminal, and the energy storage system is a mobile phone battery; or, the first equipment is factory equipment, and the energy storage system is an industrial energy storage battery; or, the first equipment is a wind turbine, and the energy storage system is a wind energy storage battery system; or, the first equipment is a solar panel, and the energy storage system is a solar energy storage battery, etc., without limitation.

[0194] Optionally, during the process of utilizing the system's operating electrical energy, the system's operating electrical energy can usually be fed back to the first device, thereby realizing an energy recycling mechanism based on the first device's electrical energy-heat energy-electrical energy.

[0195] It is worth noting that the above are merely illustrative examples, and the embodiments of this application are not limited thereto.

The network providing these resources is called the "cloud." From the user's perspective, resources in the "cloud" are infinitely scalable, readily available, on-demand, expandable, and pay-as-you-go. As a provider of basic cloud computing capabilities, a cloud computing resource pool (referred to as a cloud platform, generally called an IaaS (Infrastructure as a Service) platform) is established, deploying various types of virtual resources within the pool for external customers to choose from. The cloud computing resource pool mainly includes: computing devices (virtualized machines containing operating systems), storage devices, and network devices.

[0198] The aforementioned servers can be independent physical servers, server clusters or distributed systems composed of multiple physical servers, or cloud servers providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.
