Description

Technical Field

[0001] This application relates to the field of energy storage system technology, and in particular to a chassis, liquid-cooled air conditioner and energy storage system. Background Technology

[0002] An energy storage system is a system used to store and release electrical energy, involving the conversion between electrical and chemical energy, as well as the conversion between different types of electrical energy. In related technologies, commonly used energy storage systems, such as box-type and cabinet-type energy storage systems, integrate battery packs, power conversion devices (such as inverters, converters, and power converters containing various power electronic devices), and controllers into a cabinet. Liquid-cooled air conditioners are typically configured for this type of energy storage system as the core device of the thermal management system. Liquid-cooled air conditioners usually have a chassis and an electrical control box installed inside the chassis, which houses the control components of the liquid-cooled air conditioner.

[0003] In the process of developing this application, the inventors discovered that when users need to repair or replace the control components, they often need to remove the entire control box from the chassis. As a result, during the process of removing the control box, other electronic components located inside the chassis are easily bumped and damaged, which is quite inconvenient. Utility Model Content

[0006] In one alternative embodiment, the housing is further provided with a first limiting baffle located at the edge of the mounting opening; a second limiting baffle is provided on the side of the mounting box near the first limiting baffle, and the second limiting baffle is detachably connected to the first limiting baffle.

[0007] In one alternative embodiment, the end of the mounting box near the mounting opening is detachably connected to the cover plate, and the end of the mounting box near the mounting opening is provided with a clearance groove; the end of the mounting box near the mounting opening is provided with a first connecting hole, which communicates with the clearance groove; the cover plate is provided with a second connecting hole, which is opposite to the first connecting hole; the housing is also provided with a connector, one end of which passes through the second connecting hole and connects to the first connecting hole, and a portion of the connector is located within the clearance groove.

[0008] In one alternative embodiment, the housing includes a top plate, a bottom plate, a first side plate, a second side plate, and a third side plate. The first side plate, the second side plate, and the third side plate are sequentially arranged around the bottom plate. The top plate covers the first side plate, the second side plate, and the third side plate. The top plate and the bottom plate are arranged opposite to each other. The top plate, the bottom plate, the first side plate, the second side plate, and the third side plate together form an open receiving cavity. The mounting opening is located on the first side plate.

[0009] In one alternative embodiment, the housing further includes a fourth side panel that covers the opening of the receiving cavity, and the fourth side panel is detachably connected to the top panel, bottom panel, first side panel, and third side panel.

[0010] In one alternative embodiment, a first heat dissipation hole is provided on the second side plate, and a second heat dissipation hole is provided on the fourth side plate. The second heat dissipation hole is disposed opposite to the first heat dissipation hole, and a heat dissipation channel is formed between the second heat dissipation hole and the first heat dissipation hole. One of the first heat dissipation hole and the second heat dissipation hole is an air inlet, and the other is an air outlet.

[0011] In an optional embodiment, the housing is further provided with a liquid injection port, a liquid inlet port, and a liquid outlet port, all of which are connected to the receiving cavity. The liquid injection port, liquid inlet port, and liquid outlet port are all located on the fourth side plate, and are spaced apart from each other.

[0012] In one alternative embodiment, the housing is further provided with multiple connection ports, which are connected to the mounting cavity of the mounting box.

[0013] According to another aspect of this application, a liquid-cooled air conditioner is provided, including the chassis as described above.

[0014] According to another aspect of this application, an energy storage system is provided, which includes a liquid-cooled air conditioner as described above.

[0015] The beneficial effects of this application embodiment are: unlike the prior art, this application embodiment is provided with a box, a mounting box and a cover. The enclosure includes a receiving cavity and a mounting port connecting to the receiving cavity. A mounting box is located at the mounting port and has a mounting cavity connecting to the receiving cavity.

[0025] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see Figure 1 and Figure 2 The chassis 1000 includes a housing 10, a mounting box 20, and a cover 30. The mounting box 20 is disposed on the housing 10 and is detachably connected to the housing 10. At least a portion of the mounting box 20 is located inside the housing 10. The cover 30 is disposed on the mounting box 20 and is detachably connected to the mounting box 20. The cover 30 can be used to open or close the mounting box 20. The housing 10, the mounting box 20, and the cover 30 are described in detail below.

[0027] For the aforementioned box 10, as Figure 1 and Figure 2 As shown, the housing 10 is provided with a receiving cavity 10a and a mounting port 10b communicating with the receiving cavity 10a. The receiving cavity 10a can be used to accommodate electronic components of the liquid-cooled air conditioner, and the mounting port 10b is used for mounting the mounting box 20. The housing 10 includes a top plate 11, a bottom plate 12, a first side plate 13, a second side plate 14, and a third side plate 15. The first side plate 13, the second side plate 14, and the third side plate 15 are sequentially surrounded on the bottom plate 12, and the top plate 11 covers the first side plate 13, the second side plate 14, and the third side plate 15. The top plate 11 and the bottom plate 12 are arranged opposite to each other. The top plate 11, the bottom plate 12, the first side plate 13, the second side plate 14, and the third side plate 15 enclose the receiving cavity 10a with an open opening. In some embodiments, the mounting port 10b is located on the first side plate 13. The housing 10 is basically rectangular. The electronic components of the liquid-cooled air conditioner can enter the receiving cavity 10a from the open opening.

[0028] It is understood that the connection methods between the top plate 11, bottom plate 12, first side plate 13, second side plate 14 and third side plate 15 include, but are not limited to, screw connection, snap-fit, welding, riveting, magnetic attraction, etc. As for the shape of the box 10, this application does not make specific limitations. The box 10 can be a cuboid, a cube or other shapes.

[0029] In some embodiments, the housing 10 further includes a fourth side plate 16, which covers the opening of the receiving cavity 10a. The fourth side plate 16 is detachably connected to the top plate 11, the bottom plate 12, the first side plate 13, and the third side plate 15. The fourth side plate 16 can be used to open or close the receiving cavity 10a, facilitating the repair or replacement of electronic devices located within the receiving cavity 10a.

[0030] In some embodiments, please refer to the following: Figure 3 and Figure 4 The second side plate 14 is provided with a first heat dissipation hole 101, and the fourth side plate 16 is provided with a second heat dissipation hole 102. The second heat dissipation hole 102 is arranged opposite to the first heat dissipation hole 101, and a heat dissipation channel (not shown) is formed between the second heat dissipation hole 102 and the first heat dissipation hole 101. One of the first heat dissipation hole 101 and the second heat dissipation hole 102 is an air inlet, and the other is an air outlet. External air can enter the heat dissipation channel through the air inlet and flow through the channel, transferring the heat generated by the electronic devices located in the heat dissipation channel to the air outlet for discharge from the receiving cavity 10a, thereby achieving heat dissipation for the electronic devices.

[0031] In some embodiments, please refer to the following: Figure 5 The housing 10 is also equipped with a liquid injection port 103, a liquid inlet port 104, and a liquid outlet port 105. All three ports are connected to the receiving cavity 10a and are located on the fourth side plate 16, with intervals between them. The liquid injection port 103 is typically used to connect to a liquid storage tank or external liquid storage tank in a liquid-cooled air conditioner, primarily for replenishing the system with coolant. The liquid inlet port 104 and the liquid outlet port 105 are used to connect to a liquid cooling plate or cooling channel. Coolant enters through the liquid inlet port 104, flows through the interior of the liquid cooling plate, and exits through the liquid outlet port 105, effectively carrying away heat generated by the heat-generating elements in contact with the liquid cooling plate, thus achieving heat dissipation for the heat-generating elements.

[0032] In some embodiments, such as Figure 2As shown, a first limiting baffle 106 is also provided on the housing 10. The first limiting baffle 106 is located at the edge of the mounting opening 10b. The first limiting baffle 106 can cooperate with the components on the mounting box 20 to achieve the limiting and fixing of the mounting box 20.

[0033] In some embodiments, the housing 10 is further provided with a connector 107, which is used to connect the mounting box 20 and the cover plate 30.

[0034] For the aforementioned mounting box 20 and cover plate 30, as Figure 2 As shown, the mounting box 20 is disposed at the mounting port 10b, and the mounting box 20 is provided with a mounting cavity 20a communicating with the receiving cavity 10a. The mounting box 20 is detachably connected to the housing 10. At least a portion of the mounting box 20 is located inside the receiving cavity 10a. A cover plate 30 is disposed on the mounting port 10b, and the cover plate 30 is detachably connected to the mounting box 20. The cover plate 30 can be used to open or close the mounting cavity 20a. The mounting box 20 is used for the installation of external control components. For example, the control components in a liquid-cooled air conditioner can be installed in the mounting cavity 20a. When users need to repair or replace the control components located inside the mounting box 20, they only need to open the cover 30 to directly repair or replace the control components. Simultaneously, during the installation process, the control components can be directly installed inside the mounting box 20, and then the cover 30 can be closed. Therefore, users do not need to remove the entire control box from the chassis when repairing or replacing the control components, thus reducing the risk of the control box colliding with other electronic components inside the chassis and causing damage. This is more convenient and also improves the installation efficiency of the control components, thereby increasing the assembly efficiency of the liquid-cooled air conditioner. It is understood that the detachable connection between the cover 30 and the mounting box 20 includes, but is not limited to, screw connections, snap-fit ​​connections, riveting, magnetic attraction, etc.

[0035] In some embodiments, a second limiting baffle 201 is provided on the side of the mounting box 20 near the first limiting baffle 106. The second limiting baffle 201 is detachably connected to the first limiting baffle 106. When the mounting box 20 is installed at the mounting opening 10b of the housing 10, the first limiting baffle 106 on it can cooperate with the second limiting baffle 201 to limit the mounting box 20. Afterward, the second limiting baffle 201 and the first limiting baffle 106 can be connected by screws or other fasteners to fix the mounting box 20 to the housing 10.

[0036] In some embodiments, please refer to the following: Figure 6The mounting box 20 is detachably connected to the cover plate 30 at one end near the mounting opening 10b. A clearance groove 20b is provided around the end of the mounting box 20 near the mounting opening 10b, and a first connecting hole 202 is provided at the same end, communicating with the clearance groove 20b. The cover plate 30 has a second connecting hole 301, which is opposite to the first connecting hole 202. One end of the connector 107 passes through the second connecting hole 301 and connects to the first connecting hole 202, with a portion of the connector 107 located within the clearance groove 20b. The connector 107 is provided to connect the cover plate 30 and the mounting box 20. The clearance groove 20b provides clearance space for the connector 107 to connect the cover plate 30 and the mounting box 20, reducing damage to the edges of the mounting box 20 caused by the connector 107. In some embodiments, the connector 107 can be a screw, rivet, etc.

[0037] In some embodiments, such as Figure 5 As shown, the enclosure 10 is also provided with multiple connection ports 108, which are connected to the mounting cavity 20a of the mounting box 20. The control component of the liquid-cooled air conditioner is installed in the mounting cavity 20a. The multiple connection ports 108 on the enclosure 10 can be used to electrically connect with the control component located in the mounting cavity 20a. External electrical equipment can be plugged into the connection ports 108 to realize the electrical connection between the external electrical equipment and the control component.

[0038] In this embodiment, a housing 10, a mounting box 20, and a cover 30 are provided. The housing 10 has a receiving cavity 10a and a mounting opening 10b communicating with the receiving cavity 10a. The mounting box 20 is located at the mounting opening 10b and has a mounting cavity 20a communicating with the receiving cavity 10a. The mounting box 20 is detachably connected to the housing 10, and at least a portion of the mounting box 20 is located within the receiving cavity 10a. The mounting box 20 is used for mounting external control components. The cover 30 covers the mounting opening 10b and is detachably connected to the mounting box 20. The cover 30 can be used to open or close the mounting cavity 20a, allowing the user to access the control components located within the mounting box 20. When repairing or replacing, simply open the cover 30 to directly repair or replace the control component. Simultaneously, during the installation of the control component, it can be directly installed inside the mounting box 20, and then the cover 30 can be closed. Therefore, when users need to repair or replace the control component, they do not need to remove the entire control box from the chassis, thus reducing the risk of the control box colliding with other electronic components inside the chassis and causing damage. This is more convenient and also improves the installation efficiency of the control component, thereby increasing the assembly efficiency of the liquid-cooled air conditioner.
