[0038] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0039] In the description of this utility model, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications will also change accordingly.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] The supercharging host in this supercharging container converts the input 380V AC power into approximately 1000V DC power for output to the charging pile, thus enabling rapid, high-power charging of electric vehicles. Converting AC to DC is called rectification, but rectification inevitably results in some energy loss as heat. Assuming a current conversion efficiency of 95% for a 600kW supercharging host, 5% of that is heat loss, meaning the supercharging host dissipates approximately 30kW of power as heat. This heat loss not only raises the internal temperature, reducing the efficiency of electronic components, but also significantly increases the risk of thermal runaway and potential hazards.

[0042] Based on this, please see Figure 1 and Figure 2As shown, the supercharged container provided in this embodiment of the present invention includes a container body 101 and a heat dissipation system, wherein the heat dissipation system is used to ventilate and dissipate heat from the interior space of the supercharged container 10.

[0043] For example, such as Figure 1 As shown, the supercharged container 10 may include a container body 101 that is generally rectangular in shape. The container body 101 may be formed by an upper container wall 11, a lower container wall 12, a front container wall 13, a rear container wall 14, a left container wall 15, and a right container wall 16. It is understood that the container body 101 may also have other shapes, and this utility model does not specifically limit them.

[0044] See Figure 3 and Figure 4 As shown, the interior of the supercharging container 10 is divided into a supercharging host compartment 17, a battery compartment 18, and an equipment compartment 19 using partition walls 102. The supercharging host compartment 17 is mainly used to house the supercharging host. The battery compartment 18 is mainly used to house the energy storage battery clusters. The equipment compartment 19 is mainly used to house the power distribution cabinet, energy storage combiner cabinet, energy storage converter, etc. The cooling system provides ventilation and heat dissipation for each compartment.

[0045] See Figure 1 , Figure 2 and Figure 5 As shown, the heat dissipation system of this embodiment includes at least one first air inlet 20, at least one first air outlet 21, at least one cooling fan 22, a detection unit 30, and a control unit 40. Specifically, each first air inlet 20 and each first air outlet 21 is respectively disposed on the wall of the supercharger compartment 17. Each first air inlet 20 is used to allow external air to enter the interior of the supercharger compartment 17. Each first air outlet 21 is used to allow air inside the supercharger compartment 17 to flow outward. The cooling fan 22 is disposed at the first air outlet 21. Each cooling fan 22 is used to accelerate the airflow speed and improve the heat dissipation effect.

[0046] For example, such as Figure 4 and Figure 5 As shown, the walls of the supercharger compartment 17 can be the front wall 13, the front half of the left wall 15, and the front half of the right wall 16. Therefore, each first air inlet 20 can be located on at least one of the front wall 13, the front half of the left wall 15, and the front half of the right wall 16. Each first air outlet 21 can be located on at least one of the front wall 13, the front half of the left wall 15, and the front half of the right wall 16.

[0047] In one embodiment, the first air inlet 20 and the first air outlet 21 may be respectively located on opposite side walls of the supercharger main unit compartment 17. For example, the supercharger container has side doors on both sides in the width direction, and the first air inlet 20 and the first air outlet 21 are respectively located on opposite side doors. For instance, the front half of the right wall 16 and the front half of the left wall 15 may each be formed as a side door structure, and the first air inlet 20 and the first air outlet 21 may be respectively located on the left and right side doors.

[0048] In this embodiment, the first air inlet 20 and the first air outlet 21 are positioned opposite each other, allowing air to circulate within the supercharger compartment 17, thereby accelerating airflow and improving heat dissipation. It is understood that in other embodiments, the positions of the first air inlet 20 and the first air outlet 21 may be interchanged.

[0049] Furthermore, the first air inlet 20 and the first air outlet 21 are located in the upper part of the side-opening door, and each cooling fan 22 is correspondingly arranged with each first air outlet 31. For example... Figure 5 As shown, there can be multiple first air inlets 20, and each first air inlet 20 can be equipped with a louver. The louvers at each first air inlet 20 can be equipped with a filter to filter dust in the air and ensure the cleanliness of the air entering the supercharger compartment 17.

[0050] There can be multiple first air outlets 21. Each first air outlet 21 is equipped with a cooling fan 22. When multiple cooling fans 22 are activated, they can quickly expel hot air from the supercharger main unit compartment 17.

[0051] In an embodiment of this invention, the detection unit 30 is disposed within the supercharger compartment 17, and is used to detect the temperature inside the supercharger compartment 17 and / or the output power of the supercharger. For example, as... Figure 1 As shown, the detection unit 30 may include a temperature sensor 31, which may be disposed inside the supercharger compartment 17. The temperature sensor 31 is used to detect the temperature inside the supercharger compartment 17.

[0052] For example, the detection unit 30 includes a power detection sensor 32, which can be located on the output circuit of the supercharger and is used to detect the output power of the supercharger. Specifically, the power detection sensor 32 can be a multimeter or power meter, etc. The power detection sensor 32 can be integrated into the supercharger.

[0053] For example, the detection unit 30 is also used to detect the humidity inside the supercharger compartment 17. For instance, the detection unit 30 includes a humidity sensor 33, which may be disposed within the supercharger compartment 17. The humidity sensor 33 is used to detect the humidity inside the supercharger compartment 17. For example, the humidity sensor 33 may be integrated into a dehumidifier.

[0054] In other embodiments, the detection unit 30 may also include a temperature and humidity sensor capable of detecting the temperature and humidity of the air inside the supercharger compartment 17. However, the present invention is not limited to this. It is understood that the detection unit 30 may also include an air quality sensor capable of detecting values ​​such as temperature, humidity, and PM2.5 in the air, as well as the concentrations of gases such as oxygen, carbon dioxide, carbon monoxide, and formaldehyde. That is, the selection of the detection unit 30 can be determined as needed.

[0055] In this embodiment of the invention, the control unit 40 is electrically connected to the detection unit 30. The control unit 40 is used to receive the detection signal from the detection unit 30 and control the start or stop of the cooling fan 22 according to the detection signal. The control unit 40 can be an Energy Management System (EMS) or a PLC controller.

[0056] Specifically, see Figure 1 The control unit 40 is electrically connected to the aforementioned temperature sensor 31, power detection sensor 32, and humidity sensor 33. The temperature sensor 31, power detection sensor 32, and humidity sensor 33 can respectively send temperature signals, power signals, and humidity signals to the control unit 40. After receiving the temperature signal, power signal, and humidity signal, the control unit 40 compares them with preset temperature thresholds, power thresholds, and humidity thresholds. Then, the control unit 40 can control the start or stop of the cooling fan 22 based on the comparison results.

[0057] For example, when the temperature signal received by the control unit 40 indicates that the temperature inside the supercharger compartment 17 is high, the control unit 40 can control the cooling fan 22 to start in order to achieve the purpose of ventilation and heat dissipation.

[0058] When the power signal received by the control unit 40 indicates that the supercharger has no output power or the output power is low, the control unit 40 can control the cooling fan 22 to stop. Conversely, when the power signal received by the control unit 40 indicates that the supercharger has a high output power, the control unit 40 can control the cooling fan 22 to start.

[0059] It is worth noting that the control unit 40 can combine temperature and power signals to ultimately control the cooling fan 22 to start or stop. For example, when the supercharger is in standby mode, or when the output power is low and the temperature inside the supercharger compartment 17 does not rise significantly, the control unit 40 will control the cooling fan 22 to stop. Conversely, when the supercharger power exceeds a certain parameter, or when the temperature inside the supercharger compartment 17 shows a significant upward trend, the control unit 40 will control the cooling fan 22 to start.

[0060] See Figure 5 In one embodiment of this utility model, the heat dissipation system of the supercharging container further includes a first air conditioner 23, which is fixedly installed on the wall of the supercharging main unit compartment 17. For example, the first air conditioner 23 may be fixedly installed on the front wall 13.

[0061] The first air conditioner 23 is connected to the interior of the supercharger compartment 17. The first air conditioner 23 is used to dehumidify and / or cool the supercharger compartment 17. For example, the air outlet of the first air conditioner 23 may be connected to the interior of the supercharger compartment 17 via a duct assembly 24. The duct assembly 24 may have multiple outlets. The duct assembly 24 allows the air outlet of the first air conditioner 23 to cover a greater portion of the interior space of the supercharger compartment 17, improving the cooling or dehumidification effect of the first air conditioner 23 on the interior space of the supercharger compartment 17.

[0062] In some embodiments, the humidity sensor 33 may be installed inside the first air conditioner 23. That is, the first air conditioner 23 may have a built-in humidity detection function. When the humidity sensor 33 inside the first air conditioner 23 detects that the humidity exceeds the standard, the first air conditioner 23 can be automatically started to dehumidify the supercharger compartment 17.

[0063] In some other embodiments, the first air conditioner 23 may also be electrically connected to the control unit 40 to dehumidify and / or cool the supercharger compartment 17 under the control of the control unit 40. For example, when the temperature signal received by the control unit 40 indicates that the temperature inside the supercharger compartment 17 is high, the control unit 40 may control the first air conditioner 23 to start to cool the supercharger compartment 17. When the humidity signal received by the control unit 40 indicates that the humidity inside the supercharger compartment 17 is high, the control unit 40 may control the first air conditioner 23 to start to dehumidify the supercharger compartment 17.

[0064] It is worth noting that the control unit 40 can also control the cooling fan 22 to start or stop by combining the detection signal from the detection unit 30 and the operating mode of the first air conditioner 23. For example, when the humidity inside the supercharger compartment 10 is high and the first air conditioner 23 is in dehumidification mode, the control unit 40 can control the cooling fan 22 to stop. This can prevent a large amount of humid air from entering the supercharger compartment 17 and reduce the impact of the cooling fan 22's operation on the dehumidification effect.

[0065] When the temperature inside the supercharger compartment 17 shows a significant upward trend and the first air conditioner 23 is in cooling mode, the control unit 40 can control the cooling fan 22 to start, so as to accelerate heat dissipation and improve the cooling effect.

[0066] See Figure 1 In one embodiment, the equipment compartment 19 is equipped with a power distribution cabinet, which is electrically connected to the cooling fan 22. The cooling system also includes a control circuit for controlling the on / off state of the power supply circuit of the cooling fan 22, the control circuit including an intermediate relay 41 and an AC contactor 42.

[0067] Specifically, the coil of the intermediate relay 41 is electrically connected to the control unit 40, forming a primary control circuit. The contacts of the intermediate relay 41 are electrically connected to the coil of the AC contactor 42, forming a secondary control circuit. The contacts of the AC contactor 42 are electrically connected to the cooling fan 22.

[0068] When the control unit 40 controls the cooling fan 22 to start, the control unit 40 sends an energizing signal to the intermediate relay 41. The coil of the intermediate relay 41 is energized and the contacts of the intermediate relay 41 are closed. Therefore, the coil of the AC contactor 42 is energized and the contacts of the AC contactor 42 can be closed, thereby starting the cooling fan 22.

[0069] When the control unit 40 stops the cooling fan 22, the control unit 40 sends a power-off signal to the intermediate relay 41. The coil of the intermediate relay 41 is de-energized and the contacts of the intermediate relay 41 open. As a result, the coil of the AC contactor 42 is de-energized and the contacts of the AC contactor 42 open, thereby stopping the cooling fan 22.

[0070] In this embodiment, the intermediate relay 41 and the AC contactor 42 enable the control unit 40 to control the start and stop of each cooling fan 22 more safely and reliably, which is beneficial to improving the operating efficiency of the cooling system.

[0071] To ensure the supercharger operates safely in an environment of approximately 10℃-25℃, and considering that 5% of its operating power is lost as heat (i.e., when the supercharger dissipates electrical energy as heat at a power of 30KW), and taking into account external environmental factors such as season and humidity, in this embodiment of the invention, the first air conditioner 23 can be a 2KW industrial air conditioner. The cooling fans 22 can be 127W axial flow fans, and the number of cooling fans 22 can be 24. This effectively removes the heat generated by the supercharger during operation from inside the container, ensuring the supercharger operates in a suitable temperature and humidity environment.

[0072] See Figure 4 and Figure 5 In one embodiment of this utility model, the heat dissipation system of the supercharging container further includes a second air inlet 50 and a second air outlet 51, which are respectively disposed on the container wall of the battery compartment 18. For example, the second air inlet 50 may be disposed on the rear container wall 14 of the supercharging container 10. The second air outlet 51 may be disposed at the rear end of the right container wall 16 of the supercharging container 10. It is understood that in other embodiments, the positions of the second air inlet 50 and the second air outlet 51 may be interchanged.

[0073] Furthermore, the cooling system of the supercharging container also includes a second air conditioner 52, which is fixedly installed on the wall of the battery compartment 18. For example, the second air conditioner 52 can be fixedly installed on the rear wall 14 of the supercharging container 10. The second air conditioner 52 communicates with the interior of the battery compartment 18. Specifically, the air vents of the second air conditioner 52 can face the interior of the battery compartment 18, and the second air conditioner 52 can cool and / or dehumidify the interior space of the battery compartment 18.

[0074] In one embodiment, the second air conditioner 52 can be electrically connected to the control unit 40 to dehumidify or cool the battery compartment 18 under the control of the control unit 40. By controlling the operation of the second air conditioner 52 through the control unit 40, the second air conditioner 52 can operate as needed, thereby facilitating intelligent management, saving energy consumption, and reducing operating costs.

[0075] Furthermore, a detection element may be installed inside the battery compartment 18. The detection element is electrically connected to the control unit 40 and is used to detect the temperature and humidity inside the battery compartment 18. The detection element may include a temperature sensor and a humidity sensor, or a temperature and humidity sensor, or an air quality sensor, etc.

[0076] In this embodiment, when the detection element detects a high temperature inside the battery compartment 18, the control unit 40 will control the second air conditioner 52 to enter the cooling mode. When the detection element detects a high humidity inside the battery compartment 18, the control unit 40 will control the second air conditioner 52 to enter the dehumidification mode. Thus, through the detection element and the control unit 40, the second air conditioner 52 can be activated and enter different operating modes according to actual needs, thereby facilitating intelligent management of the heat dissipation system and effectively ensuring that the battery compartment 18 is in a suitable temperature and humidity environment.

[0077] like Figure 5 As shown, preferably, the second air outlet 51 can be located at a higher position on the casing wall to facilitate the exhaust of hot air. It is understood that in other embodiments, a fan can be installed at the second air outlet 51 to achieve ventilation and heat dissipation for the battery compartment 18.

[0078] See Figure 4 and Figure 5 In one embodiment of this utility model, the heat dissipation system of the supercharged container further includes a third air inlet 60 and a third air outlet 61, which are respectively disposed on the container wall of the equipment compartment 19. For example, the third air inlet 60 may be disposed in the middle of the right container wall 16 of the supercharged container 10. The third air outlet 61 may be disposed in the middle of the left container wall 15 of the supercharged container 10. It is understood that in other embodiments, the positions of the third air inlet 60 and the third air outlet 61 may be interchanged.

[0079] An exhaust fan 62 may be installed at the third air outlet 61. For example, the exhaust fan 62 may be electrically connected to the control unit 40, and can be started or stopped by the control unit 40. By installing the exhaust fan 62, the ventilation and heat dissipation effect of the equipment compartment 19 can be improved.

[0080] In one embodiment, the lower half of the equipment compartment 19 is equipped with a liquid-cooled main unit, an energy storage converter, and a fire suppression control unit. The liquid-cooled main unit primarily controls the liquid-cooled piping system to exchange heat with the battery clusters within the battery compartment 18. The energy storage converter mainly performs the power conversion function for the battery clusters within the battery compartment 18, and is electrically connected to the battery clusters. The fire suppression control unit is mainly used to control the operation of the fire detection system and the automatic fire extinguishing system.

[0081] Preferably, the third air inlet 60 and the third air outlet 61 can be respectively located on the lower half of the wall of the equipment compartment 19. This facilitates convection within the equipment compartment 19 and improves the ventilation and heat dissipation effect for the equipment within the equipment compartment 19.

[0082] Optionally, a detection element may be installed inside the equipment compartment 19. The detection element is electrically connected to the control unit 40 and is used to detect the temperature and humidity inside the equipment compartment 19. The detection element may be a temperature sensor, a temperature and humidity sensor, or an air quality sensor, etc.

[0083] In this embodiment, when the detection element detects a high temperature inside the equipment compartment 19, the control unit 40 will control the exhaust fan 62 to start. In this way, through the detection element and the control unit 40, the exhaust fan 62 can be started as needed, thereby effectively ensuring that the equipment compartment 19 is in a suitable temperature and humidity environment.

[0084] The heat dissipation system of the supercharging container in this embodiment of the utility model introduces air into the supercharging host compartment 17 through the first air inlet 20, while the heat dissipation fan 22 at the first air outlet 21 can blow air out, thereby achieving the purpose of ventilation and heat dissipation of the supercharging host compartment 17, ensuring that the air inside the compartment is in a suitable temperature environment, which is conducive to the efficient and reliable operation of the supercharging host.

[0085] The detection unit 30 and control unit 40 can control the start and stop of the cooling fan 22, preventing the cooling fan 22 from running continuously, thereby reducing the power consumption of the cooling fan 22, which is conducive to energy conservation and emission reduction of the supercharged container, reducing operating costs; it can also help extend the service life of the cooling fan 22, reduce the frequency of replacing the cooling fan 22, and reduce the equipment use cost of the supercharged container.

[0086] The heat dissipation system of the supercharger container in this embodiment of the invention can achieve intelligent control of the cooling fan 22 through the detection unit 30 and the control unit 40. When the supercharger is in standby mode, or when the output power is low and the temperature inside the supercharger compartment 17 does not rise significantly, the control unit 40 will control the cooling fan 22 to stop, thereby helping to reduce energy consumption and extend the service life of the cooling fan 22.

[0087] When the humidity inside the supercharger main unit compartment 10 is high and the first air conditioner 23 is in dehumidification mode, the control unit 40 can control the cooling fan 22 to stop, thereby preventing a large amount of humid air from entering the supercharger main unit compartment 17, reducing the impact of the cooling fan 22 on the humidity inside the container, and making it more conducive to ensuring that the supercharger main unit compartment 17 is in a suitable temperature and humidity environment, thus ensuring the efficient and reliable operation of the supercharger main unit.
