Currently, containerized energy storage power stations are widely used in China and receive support from national and local policies. The technical solutions for containerized energy storage power stations are also constantly being explored and innovated.

[0003] Currently, the thermal management method for containerized energy storage power stations is mainly air cooling, which is similar to the principle of small household air conditioners. The core components of air-cooled air conditioners include compressors, condensers, fan motors, copper pipes, etc. However, the existing equipment has low cooling effect and cannot achieve precise temperature control. In addition, a large number of heat-generating devices in containerized energy storage power stations need to be cooled all year round. If the cooling is completely dependent on the air conditioning system, the air conditioning compressor needs to run for a long time, which consumes a lot of energy and reduces the service life of the cooling system.

[0008] Preferably, the mounting bracket is externally fixedly connected to a protective box that can protect the condenser, throttling device, compressor and the pipeline between them. The protective box is fitted over the outside of the condenser, throttling device, compressor and the pipeline between them and fixedly connected to the outside of the container body. The second temperature sensor is fixedly installed on the outer surface of the protective box.

[0009] Preferably, the first switching pipeline (8) is connected to the pipeline between the inlet and outlet ends of the compressor (1), and the second switching pipeline (9) is connected to the pipelines at both ends of the throttling component (3).

[0010] Preferably, a first three-way solenoid valve is installed at both ends of the first switching pipeline and at the connection points of the compressor inlet and outlet pipelines. The first three-way solenoid valve can control the opening and closing of the first switching pipeline and the compressor inlet and outlet.

[0011] Preferably, a second three-way solenoid valve is installed at the connection points between both ends of the second switching pipeline and the pipelines at both ends of the throttling component. The second three-way solenoid valve can control the opening and closing of the second switching pipeline and the pipelines at both ends of the throttling component.

[0012] Preferably, a first guide hood and a second guide hood are fixedly connected to the top of the inner sidewall of the container.

This operating mode does not require the participation of the compressor and can passively cool the interior of the containerized energy storage power station when the internal temperature is high. The switching between the two modes can reduce energy consumption and avoid the compressor from running continuously for a long time, thus extending the overall service life of the system; the liquid storage tank can adapt to the two loops, so that the working quality of the two modes is in the best state and better matches the corresponding modes, ensuring that the integrated active and passive heat conduction system can maintain the best operating state in both modes and achieve good cooling effect;

[0017] (2) The active and passive heat conduction integrated system for containerized energy storage power station can detect the temperature of each part of the container in real time by setting multiple first temperature sensors in different parts of the container.

Then, the active and passive heat conduction integrated system can achieve higher precision temperature control in the container. The setting of multiple guide hoods can make the cold air blown out by the evaporator blown to each part of the container through the guide hoods, thereby making the cold air diffusion range more uniform and effectively cooling each part of the container in a timely manner.

[0025] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 6 The embodiments are described in detail below.

[0026] This embodiment provides an integrated active and passive heat dissipation system for a containerized energy storage power station, as shown in the attached figure. Figure 1-6As shown, the system includes a compressor 1, a condenser 2, a throttling device 3, and an evaporator 4. The outlet of the compressor 1 is connected to the inlet of the condenser 2 via a pipeline. The outlet of the condenser 2 is connected to the inlet of the evaporator 4 via a pipeline. The throttling device 3 is connected in series in the pipeline between the condenser 2 and the evaporator 4 and can control the flow rate of the working fluid in the pipeline. The throttling device 3 is a throttling valve, and the working fluid in the pipeline is the refrigerant. The outlet of the evaporator 4 is connected to the inlet of the compressor 1 via a pipeline. The compressor 1, condenser 2, throttling device 3, and evaporator 4 are connected by a pipeline to form a loop. This loop is a compressor system driven by the compressor 1, which is in active refrigeration mode.

[0027] Driven by compressor 1, the working fluid output from evaporator 4 is a high-temperature gaseous state. After being compressed by compressor 1, the working fluid becomes a high-temperature liquid state and enters condenser 2. After heat exchange, the working fluid output from condenser 2 is a low-temperature high-pressure liquid state, and then flows through throttling component 3 into evaporator 4, thereby exchanging heat and cooling the container body 10 through evaporator 4.

[0028] It also includes a liquid storage tank 5, with an inlet pipe 6 and an outlet pipe 7 fixedly connected to the bottom of the liquid storage tank 5. The liquid storage tank 5 is connected in parallel to the pipeline at the outlet end of the condenser 2 through the inlet pipe 6 and the outlet pipe 7. A first one-way solenoid valve 20 and a second one-way solenoid valve 21, which can control their on / off state, are respectively fixedly installed in the middle of the inlet pipe 6 and the outlet pipe 7. The first one-way solenoid valve 20 can control the liquid in the pipeline at the outlet end of the condenser 2 to flow unidirectionally into the liquid storage tank 5 through the inlet pipe 6, and the second one-way solenoid valve 21 can control the liquid in the liquid storage tank 5 to flow unidirectionally into the pipeline at the outlet end of the condenser 2 through the outlet pipe 7.

[0029] When the cooling system is driven by compressor 1, since compressor 1 requires less refrigerant, the first one-way solenoid valve 20 can be opened by the control unit. The low-temperature, high-pressure liquid working fluid flowing out from the outlet of condenser 2 will flow into the liquid storage tank 5 through the liquid inlet pipe 6 under the action of pressure difference, thereby discharging the excess working fluid. When the working fluid content in the main pipeline is at the appropriate level for compressor operation mode, the first one-way valve 20 is closed. At this time, the working fluid content in the main pipeline is at the optimal level for compressor 1 operation mode, and the excess working fluid is temporarily stored in the liquid storage tank 5 and will not affect the main pipeline.

[0030] The refrigerant is compressed in compressor 1, at which point the refrigerant temperature and pressure rise. Then, the high-temperature, high-pressure gaseous refrigerant enters condenser 2 to release heat, thus becoming a low-temperature, high-pressure liquid refrigerant. Next, after being throttled by throttling device 3, the refrigerant becomes a low-temperature, low-pressure liquid or gas-liquid two-phase state. Finally, the refrigerant enters evaporator 4 to absorb heat and evaporate, thereby cooling the surrounding air or water and cooling the interior of container 10. The low-temperature, low-pressure liquid refrigerant that passes through evaporator 4 will become a high-temperature gas after absorbing heat, and then re-enter compressor 1, thus forming a cycle that can actively cool the interior of container 10.

[0031] It also includes a first switching pipeline 8 and a second switching pipeline 9. The first switching pipeline 8 is installed on the pipeline at the inlet and outlet of the compressor 1 and is connected in parallel with the compressor 1. The first switching pipeline 8 is connected to the pipeline between the inlet and outlet of the compressor 1. A first three-way solenoid valve 15 is installed at the connection points of the two ends of the first switching pipeline 8 with the pipeline at the inlet and outlet of the compressor 1. The first three-way solenoid valve 15 can control the opening and closing of the first switching pipeline 8 and the inlet and outlet of the compressor 1.

[0032] The second switching pipe 9 is installed on the pipe between the outlet end of the condenser 2 and the inlet end of the evaporator 4 and is connected in parallel with the throttling component. The second switching pipe 9 is connected to the pipes at both ends of the throttling component 3. A second three-way solenoid valve 16 is installed at the connection points between the two ends of the second switching pipe 9 and the pipes at both ends of the throttling component 3. The second three-way solenoid valve 16 can control the opening and closing of the pipes at both ends of the second switching pipe 9 and the throttling component 3. The evaporator 4, the first switching pipe 8, the condenser 2 and the second switching pipe 9 are connected by pipes to form another circulation loop. This circulation loop is a non-powered heat pipe system, which is a passive refrigeration mode.

[0033] When compressor 1 is not in use, the first three-way solenoid valve 15 and the second three-way solenoid valve 16 can be controlled by the control unit to connect the first switching pipeline 8 and the second switching pipeline 9 to the main pipeline, while the pipelines at both ends of compressor 1 and the pipelines at both ends of throttling component 3 are closed, forming another circulation loop connecting evaporator 4, first switching pipeline 8, condenser 2 and second switching pipeline 9. This switches the system from compressor 1-driven to passive operation. In this mode, more working fluid is required, so the second one-way valve 21 on the liquid outlet pipe 6 can be opened. Since compressor 1 is not involved in operation, the pressure at the outlet of condenser 2 decreases, and the high-pressure liquid working fluid stored in the liquid storage tank 5 will flow into the main pipeline under the action of pressure difference. When the working fluid content in the main pipeline is suitable for this operating mode, the second one-way solenoid valve 21 is closed. At this time, the liquid storage tank 5 no longer participates in the operation of the main pipeline and will not affect the main pipeline.

[0034] The high-pressure liquid refrigerant discharged from the liquid storage tank 5 flows through the second switching pipe 9 into the evaporator 4 under the pressure difference between the upper and lower parts of the main pipeline. The evaporator 4 absorbs heat from the container body 10 to cool its interior, and the working fluid is converted into a high-temperature gaseous state. The high-temperature gaseous working fluid has a lower pressure and, under its own buoyancy, continues to flow through the first switching pipe 8 into the condenser 2. The condenser 2 condenses the high-temperature gaseous working fluid back into a low-temperature liquid state and continues to circulate it to the evaporator 4, thus forming a passive heat dissipation system, which can reduce power consumption and extend the service life of the overall system.

[0035] It also includes a container body 10 equipped with an energy storage power station, a first temperature sensor 11 and a second temperature sensor 12. The compressor 1 and the condenser 2 are both located on one side of the top of the container body 10. A mounting bracket 13 is fixedly connected to the upper surface of the container body 10 to place the condenser 2 and raise its height. The condenser 2 is fixedly connected to the outside of the mounting bracket 13. The evaporator 4 is fixedly installed on the top of the inner wall of the container body 10, and the pipes at its inlet and outlet ends pass through the container body 10. The condenser 2 and the evaporator 4 have a certain positive height difference in the vertical direction. The mounting bracket 13 can make a certain positive height difference between the condenser 2 and the evaporator 4. When the passive heat dissipation mode is adopted, the heat dissipation of the integrated system will increase with the increase of the positive height difference between the absolute installation height of the condenser 2 and the evaporator 4. Therefore, the height of the condenser 4 can be set as high as possible higher than the height of the evaporator 4. Correspondingly, due to the increase in the length of the pipeline, the working mass in the entire integrated system will also change, which needs to be calculated and considered when charging the working mass.

[0036] The number of first temperature sensors 11 is several, and the several first temperature sensors 11 are evenly installed on the inner side wall of the container body 10. The actual temperature inside the container body 10 can be accurately measured by the several first temperature sensors 11, and then the system can be precisely controlled to ensure sufficient heat dissipation inside the container body 10.

[0037] The mounting bracket 13 is externally fixedly connected to a protective box 14 that protects the condenser 2, the throttling component 3, and the compressor 1 and the pipelines between them. The protective box 14 is fitted over the outside of the condenser 2, the throttling component 3, and the compressor 1 and the pipelines between them and is fixedly connected to the outside of the container body 10. The protective box 14 has an openable door on its side near the compressor 1, which allows the operator to open the door to add refrigerant to the compressor 1. The second temperature sensor 12 is fixedly installed on the outer surface of the protective box 14. The second temperature sensor 12 can measure the external temperature of the container body 10, thereby selecting the active cooling mode or the passive cooling mode based on the temperature difference between the external temperature and the internal temperature of the container body 10.

[0038] The first temperature sensor 11 and the second temperature sensor 12 are respectively connected to the control unit, which sends the collected internal and external temperatures of the container body 10 to the control unit. The control unit obtains the actual external and internal temperatures and calculates the temperature difference. After comparing it with a preset threshold in the control unit, it selects between active cooling mode and passive cooling mode. For example, when the external temperature or internal temperature of the container body 10 is high, the active cooling mode is run, and the compressor 1 actively cools the interior of the container body 10. When the external temperature or internal temperature of the container body 10 is low, the passive cooling mode can be used for energy conservation. The passive cooling mode only requires the operation of the condenser fan in the condenser 2 and the evaporator fan in the evaporator 4, so the energy utilization rate is high. Moreover, it starts when the indoor temperature difference is large, and at the same time avoids the possibility that the compressor 1 may exceed the safe operating range when the external ambient temperature of the container body 10 is low.

[0039] A first guide hood 17 and a second guide hood 18 are fixedly connected to the top of the inner wall of the container body 10. The first guide hood 17 is sleeved on the outside of the evaporator 4 and fixedly connected to the top of the inner wall of the container body 10. An air guide pipe 19 is fixedly connected to the outside of the first guide hood 17, and the air guide pipe 19 communicates with the inside of the first guide hood 17 and corresponds to the air outlet of the evaporator 4. There are four second guide hoods 18, and the four second guide hoods 18 are fixedly installed at equal intervals on the top of the inner wall of the container body 10. The four second guide hoods 18 are interconnected through the air guide pipes 19 and are all connected to the inside of the first guide hood 17, blowing out from the air outlet of the evaporator 4. A portion of the cold air will enter multiple second guide hoods 18 through the air duct 19. Both the first guide hood 17 and the second guide hood 18 are downward-opening fan-shaped structures that can guide the cold air, ensuring that the cold air is blown directly downwards by the first guide hood 17 and the second guide hood 18. This prevents the energy storage equipment from being directly exposed to cold air for a long time, which would generate moisture. At the same time, it can also ensure overall cooling inside the container 10. The multiple second guide hoods 18 can divert the cold air, allowing it to be blown to various parts inside the container 10, ensuring that the cold air blown into the container 10 is more dispersed and preventing large temperature differences between different parts inside.

[0040] The compressor 1, condenser 2, throttling component, evaporator 4, first temperature sensor 11, second temperature sensor 12, first three-way solenoid valve 15, second three-way solenoid valve 16, first one-way solenoid valve 20 and second one-way solenoid valve 21 are all electrically connected to the control unit.

[0041] In summary, the operating steps of this integrated active and passive heat dissipation system for containerized energy storage power stations are as follows:

[0042] 1. When the external temperature or internal temperature of the container body 10 is high, the active cooling mode is activated. The refrigerant is compressed in the compressor 1. At this time, the refrigerant temperature rises and the pressure increases. Then, the high temperature and high pressure gaseous refrigerant enters the condenser 2 to release heat, thus becoming a low temperature and high pressure liquid refrigerant. Excess refrigerant in the main pipeline can be stored in the liquid storage tank 5.

[0043] 2. Next, after being throttled by the throttling component 3, the refrigerant becomes a low-temperature, low-pressure liquid or gas-liquid two-phase state. Finally, the refrigerant enters the evaporator 4 to absorb heat and evaporate, thereby cooling the surrounding air or water and cooling the interior of the container body 10. The low-temperature, low-pressure liquid refrigerant that passes through the evaporator 4 will become a high-temperature gas after absorbing heat, and then re-enter the compressor 1, thus forming a cycle.

[0044] 3. When the external temperature of the container body 10 is low or the internal temperature is lower than the preset threshold, a passive refrigeration mode can be adopted. The first three-way solenoid valve 15 and the second three-way solenoid valve 16 can be controlled by the control unit to connect the first switching pipeline 8 and the second switching pipeline 9 to the main pipeline, while the pipelines at both ends of the compressor 1 and the pipelines at both ends of the throttling component 3 are closed, forming another circulation loop connecting the evaporator 4, the first switching pipeline 8, the condenser 2 and the second switching pipeline 9.

[0045] 4. The high-pressure liquid refrigerant discharged from the liquid storage tank 5 will flow through the second switching pipe 9 into the evaporator 4 under the action of the pressure difference between the upper and lower parts of the main pipeline. After the evaporator 4 absorbs heat from the container body 10 and cools its interior, the working fluid will be converted into a high-temperature gaseous state. The high-temperature gaseous working fluid has a lower pressure and, under the action of its own buoyancy, will continue to flow through the first switching pipe 8 into the condenser 2. The condenser 2 will condense the high-temperature gaseous working fluid back into a low-temperature liquid state and continue to circulate it to the evaporator 4, thus forming a passive heat dissipation system.

[0046] The above description is only for illustrating the present invention and should be understood as not being limited to the above embodiments. Various modifications that conform to the spirit of the present invention are within the protection scope of the present invention.
