[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following is for reference. Figures 1-9 The electrical control box 5 of the thermal management system 100 according to an embodiment of the present invention is described.

[0043] The thermal management system 100 in this application can be applied to energy storage equipment (such as energy storage battery cabinet). In the thermal management system 100, a refrigerant circulation path is provided, and the refrigerant circulation path is provided with components such as compressor 23, throttling device 22, and condenser 24. The electrical control box 5 is a control module in the thermal management system 100 used to control the operation of the equipment.

[0044] Among them, reference Figure 5 The electrical control box 5 includes a working module and a housing. The working module in the electrical control box 5 is used to control the operation of the equipment in the thermal management system 100, so as to adjust the operating status of the equipment in the thermal management system 100 according to the heat exchange requirements. For example, controlling the compressor 23 to start or stop.

[0045] Furthermore, the housing is provided with an installation cavity and a heat exchange channel. The working module is installed inside the installation cavity, and the heat exchange medium in the refrigerant circulation path can flow through the heat exchange channel. The heat exchange medium can exchange heat with the working module inside the installation cavity to reduce the temperature of the working module and prevent the working module from overheating.

[0046] It is understandable that the heat exchange medium circulates in the refrigerant circulation path, and the casing is equipped with heat exchange channels, which are part of the refrigerant circulation path. When the heat exchange medium flows through the heat exchange channels on the casing, it can exchange heat with the working module inside the mounting cavity to remove heat and reduce the temperature of the working module.

[0047] It should be noted that heat will be generated during the operation of the working module, which will raise the temperature inside the mounting cavity. The heat exchange channel is located on the casing, and the heat exchange medium in the heat exchange channel can exchange heat with the air inside the mounting cavity to remove the heat from the mounting cavity, thereby reducing the ambient temperature inside the mounting cavity and thus reducing the temperature of the working module.

[0048] In related technologies, electrical control boxes typically reduce internal temperature by using fans to vent air to the outside of the box. This necessitates the inclusion of an exhaust structure on the control box, compromising its airtightness and making it susceptible to contamination, thus increasing the risk of damage to the internal working modules. Furthermore, air-cooled heat exchange is inefficient and cannot meet the temperature regulation requirements of the control box's internal components.

[0049] In this application, the electrical control box 5 is equipped with a heat exchange channel. The heat exchange medium in the refrigerant circulation path can exchange heat with the working module inside the electrical control box 5 as it flows through the heat exchange channel, thereby reducing the temperature of the working module and preventing it from overheating. In this application, heat exchange between the working module and the heat exchange medium in the refrigerant circulation path eliminates the need for an air outlet structure on the box body, ensuring the box body's airtightness and providing good protection for the working module. Compared to air-cooled heat dissipation, this application achieves significantly higher heat exchange efficiency by using a heat exchange medium (i.e., refrigerant, such as fluoride) to exchange heat with the working module, fully meeting the heat dissipation requirements of the electrical control box 5 and maintaining its temperature within a suitable operating temperature threshold range (e.g., 55℃-60℃), thus improving the operational reliability of the electrical control box 5.

[0050] According to the embodiment of this application, the heat exchange medium in the refrigerant circulation path of the electrical control box 5 can flow through the heat exchange channel and exchange heat with the working module inside the electrical control box 5, thereby reducing the temperature inside the electrical control box 5, preventing the temperature of the electrical control box 5 from becoming too high, and the heat dissipation method of exchanging heat with the heat exchange medium is highly efficient and can meet the heat dissipation requirements of the electrical control box 5.

[0051] In some embodiments of this application, heat exchange channels are formed in the wall of the box, thereby integrating the heat exchange channels into the box, eliminating the need for separate heat exchange components, reducing the number of components in the electrical control box 5, and reducing the difficulty of arranging and installing the working modules in the electrical control box 5.

[0052] In some other embodiments of this application, the housing includes a housing body 52 and a heat exchanger. The housing body 52 forms the aforementioned mounting cavity, the heat exchanger is disposed within the mounting cavity, and a heat exchange flow channel is formed on the heat exchanger. This allows for heat exchange between the heat exchanger and the working module within the mounting cavity, reducing the manufacturing difficulty of the housing. Furthermore, the heat exchanger can be positioned at the high-power working module according to heat exchange requirements, effectively cooling the high-heat-generating working module.

[0053] It is understandable that the electrical control box 5 contains multiple working modules, such as: filter board module 513, main board module 515, compressor drive module 511, etc. Taking compressor drive module 511 and main board module 515 as examples, during operation, the heat generated by compressor drive module 511 is more than that generated by main board module 515, resulting in a higher temperature in the area where compressor drive module 511 is installed in the mounting cavity. Therefore, heat exchange components can be arranged near the installation position of compressor drive module 511 to improve the heat exchange efficiency of electrical control box 5 near compressor drive module 511.

[0054] In a further embodiment of this application, the heat exchanger is constructed as a heat exchange plate, which can be fitted and matched with the surface of the box to connect the heat exchange plate to the box, and a heat exchange flow channel is formed in the heat exchange plate.

[0055] The heat exchanger is constructed as a plate-like structure (i.e., a heat exchange plate). The heat exchange plate has a simple structure, is easy to process and form, and its regular structure facilitates its arrangement within the mounting cavity. Furthermore, the plate-like structure allows for easy alignment with the working module, thereby maximizing the heat exchange effect of the heat exchanger on the working module.

[0056] Optionally, the heat exchange plate can be made of aluminum alloy, which has good thermal conductivity and can ensure the heat exchange efficiency between the heat exchange medium and the internal components of the box body 52.

[0057] like Figure 5 As shown, in some embodiments of this application, the working module includes a compressor drive module 511. The compressor drive module 511 is used to drive the compressor 23 in the refrigerant circulation path to operate. The compressor drive module 511 can exchange heat with the heat exchange element to reduce the temperature at the compressor drive module 511, prevent the temperature of the compressor drive module 511 from being too high, and improve the working reliability and stability of the compressor drive module 511.

[0058] It is understood that a compressor 23 is provided in the refrigerant circulation path. The compressor 23 is used to compress and drive the heat exchange medium. The compressor 23 can draw the heat exchange medium from the low-pressure area and send it to the high-pressure area for cooling and condensation after compression. The heat is then dissipated into the air through the condenser 24, changing the heat exchange medium from a gaseous state to a liquid state. In this application, the compressor drive module 511 in the electrical control box 5 is used to control the operation of the compressor 23 to meet the refrigerant circulation requirements in the refrigerant circulation path.

[0059] Reference Figure 9 In some embodiments of this application, the thermal management system 100 is provided with multiple refrigerant circulation paths, and the working module includes multiple compressor drive modules 511. The multiple compressor drive modules 511 are configured one-to-one with the compressors 23 in the multiple refrigerant circulation paths, and the multiple compressor drive modules 511 are respectively used to drive the operation of their corresponding compressors 23.

[0060] Setting up multiple refrigerant circulation paths can improve the heat exchange efficiency of the thermal management system 100 and also enhance its operational stability. For example... Figure 9 As shown, the thermal management system 100 is equipped with two refrigerant circulation paths connected in parallel. The two refrigerant circulation paths can be operated independently, so that at least one of the two refrigerant circulation paths can be selectively controlled to operate according to heat exchange requirements.

[0061] Furthermore, it can be understood that the two refrigerant circulation paths are independent of each other. When the equipment in one refrigerant circulation path (such as compressor 23) fails, the other refrigerant circulation path can be controlled to ensure that the thermal management system 100 still has the heat exchange function and prevents it from affecting the operation of the energy storage equipment.

[0062] It should be noted that the thermal management system 100 is applied to energy storage devices, which also include battery systems. The battery system can store electrical energy, and the thermal management system 100 can adjust the operating temperature of the battery system to keep it within a suitable operating temperature threshold range, thereby ensuring the charging and discharging efficiency of the battery system.

[0063] In this application, when a device in the refrigerant circulation path malfunctions, the refrigerant circulation path should not be immediately shut down to ensure the stable operation of the battery system. The thermal management system 100 is equipped with multiple refrigerant circulation paths. Even if a device in one of these paths malfunctions, the cooling function of the thermal management system 100 can be achieved by controlling the operation of the remaining refrigerant circulation paths, thus ensuring the stable operation of the energy storage device.

[0064] In some embodiments of this application, there are multiple heat exchangers, and each heat exchanger is configured in a one-to-one correspondence with a multiple compressor drive module 511. Moreover, the heat exchange channel of each heat exchanger is connected in series in the refrigerant circulation path of the compressor 23 controlled by the compressor drive module 511 that cooperates with it in heat exchange.

[0065] Reference Figure 5 and Figure 9 Two compressor drive modules 511 are installed inside the mounting cavity. Two heat exchange components are installed between the two compressor drive modules 511 and the inner wall of the mounting cavity. The two heat exchange components are respectively installed corresponding to the two compressor drive modules 511, so that the electrical control box 5 can be cooled through the two compressor components.

[0066] The heat exchange channels in the two heat exchange components are connected in series in the refrigerant circulation path of the compressor 23 controlled by the compressor drive module 511, which is respectively set with them. This makes the heat exchange of the heat exchange components more targeted and can prevent the local temperature in the electrical control box 5 from being too high.

[0067] Specifically, taking the thermal management system 100 as an example, which has two refrigerant circulation paths and two compressor drive modules 511 installed in the installation cavity, the two compressor drive modules 511 are the first compressor drive module 511 and the second compressor drive module 511, and the two refrigerant circulation paths are the first refrigerant circulation path and the second refrigerant circulation path, respectively. The first compressor drive module 511 is used to drive the compressor 23 in the first refrigerant circulation path to operate, and the second compressor drive module 511 is used to drive the compressor 23 in the second refrigerant circulation path to operate.

[0068] The mounting cavity also includes a first heat exchanger and a second heat exchanger. The first heat exchanger is positioned opposite to the first compressor drive module, and the second heat exchanger is positioned opposite to the second compressor drive module. The heat exchange channel of the first heat exchanger is connected in series in the first refrigerant circulation path, and the heat exchange channel of the second heat exchanger is connected in series in the second refrigerant circulation path. When the first compressor drive module drives the compressor in the first refrigerant circulation path, the heat exchange medium circulates in the first refrigerant circulation path and flows through the first heat exchanger. The first heat exchanger can fully exchange heat with the first compressor drive module to prevent the temperature at the first compressor drive module from becoming too high. When the second compressor drive module drives the compressor in the second refrigerant circulation path, the heat exchange medium circulates in the second refrigerant circulation path and flows through the second heat exchanger. The second heat exchanger can fully exchange heat with the second compressor drive module to prevent the temperature at the second compressor drive module from becoming too high.

[0069] It is understandable that when the compressor drive module 511 controls the compressor 23 to run, the compressor drive module 511 will generate heat. By connecting the heat exchanger corresponding to the compressor drive module 511 in series in the refrigerant circulation path of the compressor 23 controlled by the compressor drive module 511, the heat exchange medium in the heat exchanger corresponding to the compressor drive module 511 can circulate when the compressor drive module 511 is working. This improves the heat exchange effect at the location of the compressor drive module 511, making the heat exchange of the heat exchanger more targeted and effectively preventing the local temperature in the electrical control box 5 from becoming too high.

[0070] It should be noted that the number of heat exchange components can be greater than the number of compressor drive modules 511. This satisfies the requirement of setting heat exchange components to correspond one-to-one with compressor drive modules 511, and also allows heat exchange components to correspond to other working modules in the electrical control box 5, thereby fully improving the heat exchange effect of the electrical control box 5.

[0071] like Figure 5 As shown, in some embodiments of this application, the working module further includes a fan power module 512, which is disposed in the mounting cavity and can be disposed opposite to the heat exchanger and exchange heat with the heat exchanger.

[0072] The thermal management system 100 is also equipped with an air outlet device (such as a fan). The air outlet device is set in correspondence with the condenser 24 in the refrigerant circulation path and is used to increase the flow rate in the area where the condenser 24 is set, thereby improving the condensation effect of the condenser 24 on the heat exchange medium. The aforementioned fan power module 512 is used to control the operation of the fan 54.

[0073] It should be noted that the fan power module 512 is a high-power module that will generate a lot of heat during operation. By setting the fan power module 512 in a corresponding manner with the heat exchange components, the heat exchange effect at the location of the fan power module 512 can be fully improved, and the local temperature of the electrical control box 5 at the fan power module 512 can be prevented from becoming too high.

[0074] The fan power module 512 and the compressor drive module 511 can be simultaneously configured to correspond to the first heat exchanger. The fan power module 512 and the compressor drive module 511 can be arranged on the same side of the heat exchanger (e.g., the side of the heat exchanger away from the inner wall of the cavity). Alternatively, the fan power module 512 and the compressor drive module 511 can be arranged on opposite sides of the heat exchanger to ensure proper correspondence with the heat exchanger.

[0075] Combination Figure 3 and Figure 6 A separate heat exchanger can also be installed in the installation cavity. The heat exchanger is configured in correspondence with the fan power module 512, and the heat exchange channel of the heat exchanger can be connected in series with the heat exchange channel of the heat exchanger corresponding to the compressor drive module 511.

[0076] Reference Figure 3 For example, the mounting cavity is equipped with three heat exchangers: a first heat exchanger 531, a second heat exchanger 532, and a third heat exchanger 533. The first and second heat exchangers 531 and 532 are respectively associated with two compressor drive modules 511, while the third heat exchanger 533 is associated with a fan power module 512. The heat exchange channels in all three heat exchangers are constructed as part of the refrigerant circulation path, and the connection method of their heat exchange channels can be designed according to heat exchange requirements. For example, the heat exchange channel of the third heat exchanger 533 can be connected in series with the heat exchange channel of the first heat exchanger 531, or the heat exchange channel of the third heat exchanger 533 can be connected in series with the heat exchange channel of the second heat exchanger 532.

[0077] It should be noted that the heat exchange channels of the first heat exchanger 531 and the second heat exchanger 532 are respectively connected in series on two independent refrigerant circulation paths. The arrangement of connecting one of the first heat exchanger 531 and the second heat exchanger 532 in series with the third heat exchanger 533 is simple and can reduce the difficulty of pipeline layout.

[0078] like Figure 2 As shown, in some embodiments of this application, the working module includes a fan power supply module 512 and a compressor drive module 511, and the mounting cavity forms a first mounting area 521 and a second mounting area 522 arranged sequentially along a first direction. In the accompanying drawings of this application, the "first direction" refers to the length direction of the electrical control box 5.

[0079] The fan power module 512 is located in the first mounting area 521, and the compressor drive module 511 is located in the second mounting area 522. Multiple heat exchangers are located in both the first and second mounting areas. The heat exchangers in the first mounting area 521 can exchange heat with the fan power module 512, and the heat exchangers in the second mounting area 522 can exchange heat with the compressor drive module 511. Thus, the multiple heat exchangers cool the multiple working modules within the mounting cavity.

[0080] like Figure 2 As shown, the mounting cavity forms a first mounting area 521 and a second mounting area 522 along the first direction. The first mounting area 521 and the second mounting area 522 are respectively used to arrange different working modules, thereby dividing the multiple modules in the electrical control box 5 into zones, making the working modules arranged neatly and reducing the assembly difficulty of the modules in the electrical control box 5.

[0081] Meanwhile, multiple heat exchange components are installed in the installation cavity. These heat exchange components are used to exchange heat with the fan power module 512 and the compressor drive module 511, respectively. This allows the heat exchange components to correspond to the high-power modules (i.e., modules that generate a lot of heat during operation) in the electrical control box 5, thereby specifically improving the heat dissipation capacity of the area in the electrical control box 5 where the high-power modules are located and preventing the local temperature inside the electrical control box 5 from becoming too high.

[0082] In some embodiments of this application, there are multiple compressor drive modules 511, and multiple heat exchange components are provided in the second installation area 522. The multiple heat exchange components are respectively arranged in a one-to-one correspondence with the multiple compressor drive modules 511, and the heat exchange flow channel of the heat exchange component that exchanges heat with the fan power module 512 is connected in series with at least one of the multiple heat exchange components provided in the second installation area 522.

[0083] Specifically, in combination Figure 3 and Figure 6 When two compressor drive modules 511 are provided in the second installation area 522, two heat exchangers are also provided in the second installation area 522, and the heat exchanger arranged in the first installation area 521 can be connected in series with one of the two heat exchangers.

[0084] Further integration Figure 1The electrical control box 5 is also equipped with multiple refrigerant connection pipes 56. One end of the refrigerant connection pipe 56 is connected to the heat exchanger, and the other end of the refrigerant connection pipe 56 is connected to the refrigerant circulation path, so that the heat exchange medium in the refrigerant circulation path can flow into the heat exchanger through the refrigerant connection pipe 56.

[0085] like Figure 4 As shown, the refrigerant connection pipe 56 is installed through the wall of the box body 52, which reduces the difficulty of connecting the heat exchanger in series in the refrigerant circulation path. It can be understood that when the heat exchanger is constructed as a heat exchange plate, the heat exchange plate can be arranged parallel to the wall of the box body 52, which facilitates the arrangement of the heat exchange plate inside the box body 52.

[0086] A sealing sleeve 57 can be provided at the position where the refrigerant connection pipe 56 passes through the box body 52. ​​The sealing sleeve 57 is fitted on the refrigerant connection pipe 56 to improve the sealing effect between the refrigerant connection pipe 56 and the box body 52, thereby improving the sealing performance of the electrical control box 5 and forming a closed electrical control box 5. This protects the working module in the electrical control box 5 and meets the requirements for the use of the electrical control box 5 in harsh environments, such as environments with high humidity and a lot of dust.

[0087] Reference Figure 3 In some embodiments of this application, the communication port between the heat exchanger and the refrigerant connection pipe 56 is formed on the same side of the heat exchange plate. Of course, the location of the communication port between the heat exchanger and the refrigerant connection pipe 56 is not limited to this, and can be designed according to the arrangement of the heat exchanger in the mounting cavity.

[0088] Reference Figure 4 The refrigerant connection pipe 56 in this application is L-shaped. One end of the L-shaped pipe extends vertically (e.g., coplanar with the heat exchange plate), and the other end extends horizontally, so as to facilitate the refrigerant connection pipe 56 being led out from the side of the box body 52.

[0089] Understandably, when it is necessary to connect two heat exchangers in series, the refrigerant connection pipes 56 connected to the two heat exchangers can be connected in series. The connection method is simple and can save the installation space occupied by the connection structure in the box body 52, reduce the number of components arranged in the installation cavity, and reduce the difficulty of installing and arranging the working module in the box body 52.

[0090] Furthermore, the refrigerant connection pipe 56 can be constructed as a waterproof joint, which can meet the IP55 protection level and improve the waterproof effect at the refrigerant connection pipe 56.

[0091] like Figure 5As shown, in some embodiments of this application, the electrical control box 5 further includes a fan 54, which is located in the first installation area 521. The fan power module 512 and the heat exchange components are arranged sequentially in the first installation area 521 along the second direction. The fan 54 can deliver air to the fan power module 512, and the air delivery direction of the fan 54 is perpendicular to the second direction.

[0092] The second direction is perpendicular to the first direction. In the accompanying drawings of this application, the "second direction" refers to the thickness direction of the electrical control box 5. When the fan power module 512 and the heat exchanger are stacked in the thickness direction, the fan power module 512 and the heat exchanger can be fully aligned. That is, the heat exchange area corresponding to the heat exchanger and the fan power module 512 is large, which can ensure the heat exchange effect between the heat exchanger and the fan power module 512. Moreover, the arrangement is compact, so as to make reasonable use of the space in the installation cavity.

[0093] Furthermore, a fan 54 is also provided inside the mounting cavity, which can supply air to the fan power module 512 to increase the air flow speed at the fan power module 512, so that the gas can flow inside the mounting cavity (i.e., generate airflow inside the mounting cavity), improve the heat exchange efficiency of the heat exchanger, and enhance the heat exchange effect of the heat exchanger on the working module in the mounting cavity.

[0094] Understandably, when the heat exchanger is in close contact with the working module, it can directly exchange heat with the working module to reduce the temperature of the working module. When the heat exchanger is opposite to and spaced apart from the working module, it can exchange heat with the air in the mounting cavity to reduce the gas temperature in the mounting cavity, and further exchange heat with the working module through the low-temperature gas. That is, it indirectly exchanges heat with the working module by reducing the ambient temperature of the working module, thereby reducing the temperature of the working module. In particular, the air blown by the fan 54 to the fan power module 512 can form a flow of cool air in the mounting cavity, effectively preventing local heat accumulation in the electrical control box 5, and further improving the heat exchange effect between the heat exchanger and the working module.

[0095] In some embodiments of this application, the electrical control box 5 further includes a heating element 58, which is located at the air outlet of the fan 54. When the heating element 58 is turned on, it can raise the temperature at the air outlet. When the fan 54 is turned on, it will send air to the heating element 58, which can raise the air temperature sent by the fan 54, thereby forming a warm airflow within the mounting cavity, thus raising the ambient temperature within the mounting cavity and meeting the operating requirements of the electrical control box 5 in low-temperature environments.

[0096] It is understandable that when the electrical control box 5 is working in a low-temperature environment, the operation of the working modules can generate heat. However, the power of some working modules is low, resulting in temperature differences in different areas of the installation cavity. By cooperating with the fan 54 and the heating component 58, a warm airflow can be formed in the installation cavity. The flow of the warm airflow raises the ambient temperature of the installation cavity, reduces the local temperature difference in the installation cavity, and ensures the reliability and stability of the operation of the electrical control box 5.

[0097] In some embodiments of this application, the working module further includes a filter plate module 513, which is disposed in the first installation area 521 and located on the side of the fan power module 512 away from the heat exchanger. Thus, the filter plate module 513 and the fan power module 512 are arranged in two layers in the first installation area 521, and the arrangement is compact.

[0098] It is understandable that the filter board module 513 is used to eliminate power signals of a specific frequency and belongs to the low-power module in the electrical control box 5. Therefore, the filter board module 513 can be arranged on the side of the fan power module 512 away from the heat exchanger.

[0099] The filter board module 513 can be arranged along the second direction with the fan 54 and the air outlet of the fan 54 can be avoided, so that the fan power module 512 and the fan 54 are arranged on the same layer to prevent interference with the air supply of the fan 54.

[0100] In some embodiments of this application, the working module further includes a motherboard module 515, which is located in the second mounting area 522 and is situated on the side of the compressor drive module 511 away from the heat exchanger. Thus, the motherboard module 515 and the compressor drive module 511 are arranged in two layers in the second mounting area 522, resulting in a compact arrangement.

[0101] like Figure 2 As shown, in some embodiments of this application, a mounting bracket 55 is provided inside the box. The mounting bracket 55 is located at the boundary between the first mounting area 521 and the second mounting area 522. The mounting bracket 55 is provided with a first mounting part 551 and a second mounting part 552 on both sides in the first direction. The first mounting part 551 is used to connect with the filter board module 513, and the second mounting part 552 is used to connect with the main board module 515.

[0102] The mounting bracket 55 provides mounting points for the filter board module 513 and the mainboard module 515 to secure them. (See reference...) Figure 3 and Figure 5In this application, the fan power module 512 and the filter plate module 513, as well as the compressor drive module 511 and the main board module 515, are arranged in a double-layer configuration. The fan power module 512 and the compressor drive module 511 can be connected to their corresponding heat exchange components. During the assembly of the filter plate module 513 and the main board module 515, a certain gap usually needs to be reserved between the inner walls of the main body 52 to prevent interference. Therefore, an installation structure for mounting the filter plate module 513 and the main board module 515 needs to be provided in the mounting cavity.

[0103] Furthermore, a mounting structure can be formed on the inner wall of the box body 52, through which the filter board module 513 and the main board module 515 are mounted. Combined with Figure 3 and Figure 5 The length direction of the filter board module 513 and the motherboard module 515 is the same as the arrangement direction of the first mounting area 521 and the second mounting area 522. Therefore, the filter board module 513 and the motherboard module 515 can be installed and fixed by setting mounting structures on both sides of the first direction.

[0104] Reference Figure 5 It should be noted that the distance between the filter board module 513 and the main board module 515 and the side wall of the box body 52 in the third direction is relatively large. If the mounting structure is set on the two opposite inner side walls of the box body 52 in the third direction (i.e., the vertical direction of the electrical control box 5), the installation structure will be difficult to set.

[0105] In this application, by providing a mounting structure between the two opposing mounting brackets of the box body 52, the assembly requirements of the filter board module 513 and the main board module 515 can be met. Combined with... Figure 3 and Figure 5 Taking the installation of a filter board as an example, a filter board mounting part is provided on the side wall of the box body 52 opposite to the mounting bracket 55. A first mounting part 551 is provided on the left side of the mounting bracket 55. Both the first mounting part 551 and the filter board mounting part are used to install and fix the filter board module 513, so as to fix the filter board module 513 to the box body 52. ​​Taking the installation of a motherboard as an example, a motherboard mounting part is provided on the side wall of the box body 52 opposite to the mounting bracket 55. A second mounting part 552 is provided on the right side of the mounting bracket 55. Both the second mounting part 552 and the motherboard mounting part are used to install and fix the motherboard module 515, so as to fix the motherboard module 515 to the box body 52.

[0106] It should be noted that the mounting structure can be constructed as a plate structure, with mounting holes formed on the plate structure to fix the filter board module 513 or the main board module 515 through the cooperation of the mounting holes and the connectors. However, the mounting structure is not limited to a plate structure, and can also be a hinge, hinge, or other structure. The specific construction of the mounting structure can be designed according to the assembly requirements.

[0107] Understandably, a reversible installation structure reduces the difficulty of inspecting and maintaining the electrical control box 5. Combined with... Figure 1 , Figure 5 It is known that since the refrigerant connection pipe 56 is formed on one side wall of the electrical control box 5 in the second direction, maintenance on the side with the refrigerant connection pipe 56 is more difficult. Inspection and maintenance can be performed from the other side surface of the electrical control box 5 in the second direction. Taking the filter board module 513 as an example, when the filter board module 513 is rotatably connected to the mounting bracket 55 (or in the box body 52), the fan power module 512 can be exposed by flipping the filter board module 513. This simple operation improves the efficiency of disassembly and assembly of the electrical control box 5 during inspection and maintenance.

[0108] In some embodiments of this application, the mounting bracket 55 and the wall of the box body 52 used for mounting heat exchange components are spaced apart to form a clearance area. The clearance area can be cleared by the airflow blown out by the fan 54 to ensure the circulation effect of the airflow in the mounting cavity.

[0109] In some embodiments of this application, a fan 5151 is integrated in the motherboard module 515. The fan 5151 is adapted to deliver air along a second direction to the compressor drive module 511 to increase the airflow rate at the compressor drive module 511.

[0110] In some embodiments of this application, the working module further includes a frequency converter module 514. The frequency converter module 514 and the fan 54 are respectively located on opposite sides of the fan power module 512 in a third direction. The fan 54 can supply air to the fan power module 512 and the frequency converter module. The frequency converter module 514 integrates a fan assembly, and the fan assembly can supply air to the second mounting area 522. At this time, multiple air supply structures (i.e., the fan 54 and the fan assembly) are formed in the mounting cavity. Through the cooperation between the multiple air supply structures, the airflow in the mounting cavity can be well guided, thereby realizing the circulation of airflow in the mounting cavity and further improving the heat exchange effect in the electrical control box 5.

[0111] Among them, the first direction, the second direction, and the third direction are all perpendicular to each other. The "third direction" shown in the accompanying drawings of this application refers to the height direction of the electrical control box 5. In this application, the electrical control box 5 can be arranged in a vertical position in the thermal management system 100.

[0112] Reference Figure 5The fan 54 delivers air to the inverter module 514 along the third direction. The air blown out by the fan 54 can flow through the fan power module 512 and the heat exchanger. The inverter module 514 can further deliver air to the second installation area 522, thereby guiding the airflow to the right along the second direction to form a circulating airflow in the installation cavity.

[0113] In some embodiments of this application, the box body 52 is provided with a wire passage hole for routing wires so that the wire bundle can pass through. Preferably, the wire passage hole is formed on the bottom wall (i.e., the lower wall in the third direction) of the box body 52, which can effectively prevent dust accumulation at the wire passage hole.

[0114] The wiring holes are sealed to ensure the sealing effect of the electrical control box 5, making it a fully enclosed structure that can withstand various harsh environments.

[0115] In some embodiments of this application, the working module further includes a reactor module 516, which is arranged within the second mounting area 522, and the reactor module 516 and the compressor drive module 511 are arranged sequentially along a third direction. (Refer to...) Figure 5 The frequency converter module 514 and the reactor module 516 are respectively arranged in the first direction. The frequency converter can send air to the reactor side to exchange heat with the reactor through the circulating airflow.

[0116] The thermal management system 100 according to an embodiment of this application includes the aforementioned electrical control box 5. The electrical control box 5 is used to control the equipment in the thermal management system 100 to control the operating state of the thermal management system 100. The working modules in the electrical control box 5 can be used to control the operation of the equipment in the thermal management system 100, such as controlling the heating device 13 to heat, controlling the valve to open, controlling the compressor 23 to run, controlling the fan 54 to rotate, controlling the drive device 12 to run, etc. It can also be used to communicate with the sensor devices in the thermal management system 100 to obtain signals transmitted by the sensors, and control the operation of the equipment based on the signals and corresponding control logic.

[0117] In the embodiments of this application, the thermal management system 100 includes a first heat exchange system 1 and a second heat exchange system 2. The first heat exchange system 1 includes a first heat exchange flow path 11, a driving device 12 and a heating device 13. A first heat exchange medium is provided in the first heat exchange flow path 11, which can be water. The driving device 12 is used to drive the first heat exchange medium to flow in the first heat exchange flow path 11. The heating device 13 can be used to heat the first heat exchange medium to increase its temperature.

[0118] The thermal management system 100 is applied to an energy storage device, which also includes a battery system. The first heat exchange flow path 11 in the first heat exchange system 1 has an inlet 111 and an outlet 112 communicating with the battery system. The first heat exchange medium can flow into the battery system through the outlet 112 and then flow back into the first heat exchange flow path through the inlet 111. In other words, the first heat exchange medium can flow into the battery system and exchange heat with the energy storage components (such as batteries) within the battery system. The driving device 12 can be configured as a water pump, and the heating device 13 can heat the first heat exchange medium by energizing a heating wire.

[0119] It should be noted that after entering the battery system, the first heat exchange medium can flow as a heat exchange medium in the battery system, and the first heat exchange medium can exchange heat with the energy storage component directly or indirectly, thereby regulating the operating temperature of the energy storage component.

[0120] Furthermore, the second heat exchange system 2 is a refrigerant heat exchange system, that is, the second heat exchange system 2 includes a second heat exchange flow path 21 (i.e., the aforementioned refrigerant circulation flow path). The refrigerant circulation flow path is equipped with a throttling device 22, a compressor 23, a condenser 24, and other equipment. In addition, the heat exchange components integrated in the electrical control box 5 of this application are connected in series in the refrigerant circulation flow path so as to cool down the working module in the electrical control box 5 with low-temperature refrigerant and keep the temperature of the electrical control box 5 within a suitable operating temperature threshold range.

[0121] In some embodiments of this application, the thermal management system 100 further includes a heat exchanger 3, through which the first heat exchange medium and the second heat exchange medium can flow and exchange heat, thereby meeting the different heat exchange requirements of the thermal management system 100.

[0122] In this application, when it is necessary to raise the temperature of the battery system, the heating device 13 is turned on to heat the first heat exchange medium, thereby raising the temperature of the first heat exchange medium in the first heat exchange flow path 11. After the temperature is raised, the first heat exchange medium flows into the battery system from the outlet 112 and exchanges heat with the energy storage component, thereby meeting the temperature regulation requirement of raising the battery system temperature. At this time, the temperature regulation of the battery system can be achieved simply by running the first heat exchange system 1. When it is necessary to lower the temperature of the battery system, the heating device 13 is not turned on, and the refrigeration module such as the compressor 23 in the refrigerant circulation path is operated to lower the temperature of the second heat exchange medium. The first heat exchange medium and the second heat exchange medium exchange heat at the heat exchanger 3 to lower the temperature of the first heat exchange medium. After the temperature is lowered, the first heat exchange medium flows into the battery system from the outlet 112 and exchanges heat with the energy storage component, thereby meeting the temperature regulation requirement of lowering the battery system temperature. At this time, the temperature regulation of the battery system requires the simultaneous operation of the first heat exchange system 1 and the second heat exchange system 2, and during the regulation process, the first heat exchange medium and the second heat exchange medium need to exchange heat at the heat exchanger 3.

[0123] Therefore, the temperature regulation of the battery system is achieved through heat exchange with the first heat exchange medium. Specifically, the temperature of the first heat exchange medium can be increased by the heating device 13, and the temperature of the first heat exchange medium can be decreased by heat exchange with the second heat exchange medium, thereby meeting the temperature regulation requirements of the battery system for heating or cooling.

[0124] In some embodiments of this application, the first heat exchange system 1 further includes an expansion tank 14, which is connected to the first heat exchange flow path 11 to improve the reliability and stability of the first heat exchange system 1 during operation. The expansion tank 14 is used to balance the pressure in the pipeline (i.e., the first heat exchange flow path 11). The expansion tank 14 can absorb water hammer impacts caused by the opening and closing of valves and pump structures in the first heat exchange system 1, thereby improving the operational stability of the first heat exchange system 1 and extending the service life of the pipeline components and pump structures.

[0125] In some embodiments of this application, the first heat exchange system 1 further includes a drain valve 192, which is connected in series in the first heat exchange flow path 11 and is used to filter foreign matter in the flow path, thereby improving the operational stability of the first heat exchange system 1. The drain valve 192 is connected in series between the expansion tank 14 and the heating device 13, and is also between the liquid inlet of the first heat exchange flow path 11 and the heating device 13, thereby filtering the first heat exchange medium that is about to flow into the heating device 13.

[0126] It is understandable that particulate matter such as welding slag may be present in the pipeline structure supplying the first heat exchange medium. If these particles flow into the drive device 12 and the heating device 13, they will affect the equipment and pose a risk of damage. In this application, the drain valve 192 can filter the particulate matter in the first heat exchange flow path 11 to prevent the particulate matter from affecting the operation of the equipment in the first heat exchange system 1.

[0127] The drain valve 192 has a filtering function for the medium in the first heat exchange flow path 11. The size of the particles that the drain valve 192 can filter is not specifically limited here. The filter 191 in the drain valve 192 can be selected according to the requirements, such as: filter 191 20 mesh.

[0128] In some embodiments of this application, a water inlet is provided in the first heat exchange flow path 11, so that the first heat exchange medium can be added to the first heat exchange flow path 11 through the water inlet, so as to ensure that the first heat exchange medium in the first heat exchange flow path 11 is sufficient and improve the reliability and stability of the operation of the first heat exchange system 1.

[0129] Furthermore, the water inlet can be connected to the replenishment tank 15, which stores the first heat exchange medium, so that the first heat exchange medium can be replenished into the first heat exchange flow path 11 through the replenishment tank 15. When the first heat exchange medium is water, the water inlet can also be connected to a water source (such as a faucet, water tank, or other water supply equipment) to supply water to the water inlet.

[0130] In some embodiments of this application, the thermal management system 100 further includes a frame 4, which has a first mounting platform 41, a second mounting platform 42 and a third mounting platform 43 arranged sequentially from top to bottom in a vertical direction.

[0131] The second heat exchange system 2 is installed on the first mounting platform 41, the heat exchanger 3 is installed on the second mounting platform 42, and the first heat exchange system 1 is installed on the third mounting platform 43, thereby zoning the equipment in the heat management system 100 to facilitate the connection and coordination between the various devices in the heat management system 100.

[0132] Specifically, the second heat exchange system 2 is a fluorine circuit system, which can realize the cooling function of the second heat exchange system 2 through the cooperation of the refrigeration module and the second heat exchange medium (such as fluoride); the first heat exchange system 1 is a water circuit system, which can realize the heating function of the first heat exchange system 1 through the cooperation of the heating device 13 and the first heat exchange medium; the heat exchanger 3 is a device for heat exchange between the first heat exchange medium and the second heat exchange medium. When the heat exchanger 3 is arranged on the second mounting platform 42 located in the middle, the area where the first heat exchange medium and the second heat exchange medium exchange heat can be arranged between the two, thereby reasonably shortening the path length of the first heat exchange flow path 11 and the second heat exchange flow path 21, which facilitates the pipeline layout in the thermal management system 100.

[0133] It is understood that frame 4 serves as the mounting carrier for the first heat exchange system 1, the second heat exchange system 2, and the heat exchanger 3, and is used to mount and support the heat exchanger 3, the first heat exchange system 1, and the second heat exchange system 2. In this application, the first heat exchange system 1, the second heat exchange system 2, and the heat exchanger 3 are arranged on mounting platforms at different heights, allowing the water system (i.e., the first heat exchange system 1) and the refrigerant system (i.e., the second heat exchange system 2) in the heat management system 100 to be arranged in layers, facilitating the installation and maintenance of the heat management system 100. For example, when the second heat exchange system 2 malfunctions, only the baffle in the upper part of frame 4 needs to be removed to fully expose the equipment in the second heat exchange system 2, making the operating area for maintenance personnel clearer, without the need to disassemble other areas of frame 4.

[0134] In some embodiments of the present invention, the electrical control box 5 is mounted on the second mounting platform 42, thereby reducing the difficulty of arranging the electrical control box 5.

[0135] The energy storage device according to the embodiments of this application includes the above-described thermal management system, which regulates the temperature of the battery system to keep the battery system within a temperature range suitable for operation (charging and discharging).
