[0037] like Figures 1 to 4As shown, according to the implementation mode of the utility model, the first aspect of the utility model proposes a unit shell, the unit shell includes a shell body 10 and a support assembly 20, the shell body 10 includes a first side plate 11 and a second side plate 12 arranged opposite to each other, and a storage space 13 for accommodating a condenser is defined between the first side plate 11 and the second side plate 12, the support assembly 20 is arranged in the storage space 13 and connected to at least one of the first side plate 11 and the second side plate 12, and the support assembly 20 is used to support the condenser.

[0038] It is understandable that the energy storage device generates heat during operation. In order to reduce the impact of high temperature on the energy storage device, it is necessary to perform thermal management on the energy storage device through an air-cooled unit, and take away the heat generated by the energy storage device through air cooling to cool it down. The unit housing is the outer shell of the air-cooled unit, which can be a sheet metal splicing structure in a cubic shape. The interior of the housing body 10 is used to accommodate various components for installing the air-cooled unit. The first side plate 11 and the second side plate 12 can be a metal plate structure, and there is a bending portion at the edge, and the bending portion is used to connect with the front and rear plates. The first side plate 11 and the second side plate 12 are respectively located on the left and right sides of the condenser. The first side plate 11 is arranged in parallel with the second side plate 12, and the space in the middle is used to accommodate the cavity condenser and other components of the air-cooled unit. The first support member 21 can be fixed to the inner side of the first side plate 11 by welding. To ensure accurate position, a welding mark can be set on the first side plate 11 before welding, and the position of the first support member 21 is positioned according to the welding mark. Similarly, the second support member 22 is also fixed to the inner side of the second side plate 12 by welding. The support assembly 20 can be a sheet metal block or sheet metal strip welded or fixed to the shell body 10 by bolts. The support assembly 20 has an upward supporting surface, and the condenser can be placed directly on the support assembly 20 to complete the installation and fixation of the condenser. The support assembly 20 can be set to multiple supporting positions, for example, one corresponding to the left and right sides of the condenser, or one corresponding to each of the four corners of the outer shell of the condenser, so that the installation of the condenser is more stable.

[0039] The utility model arranges the support assembly 20 in the unit shell, so that the condenser can be directly placed on the support assembly 20 to achieve positioning and fixing. The installation and disassembly of the condenser can be completed by one person, the operation is convenient, and the disassembly efficiency is high.

[0040] In some embodiments of the present invention, the support assembly 20 includes a first support member 21 connected to the first side plate 11 , and an escape space 14 for escaping the pipes of the condenser is formed between the first support member 21 and the first side plate 11 .

[0041] It can be understood that the first support member 21 can be a bent structure such as an S-shape or L-shape. One end of the first support member 21 is welded or clamped to the first side panel 11, and the other end extends toward the accommodating space 13. Since the heat exchange pipelines, inlet and outlet liquid pipelines and other pipelines of the condenser are partially exposed outside the condenser shell 30, it is necessary to bypass the above-mentioned pipelines when setting the first support member 21. At this time, the first support member 21 can be set to a bent sheet metal structure, so that an avoidance space 14 for avoiding the pipelines of the condenser is formed between the first support member 21 and the first side panel 11, and there will be no interference with the above-mentioned pipelines when the condenser is installed, thereby facilitating the installation of the condenser.

[0042] In some embodiments of the present invention, the first support member 21 includes a first support portion 211 and a second support portion 212, the first end of the first support portion 211 is connected to the first side panel 11, the second end of the first support portion 211 extends in a direction away from the first side panel 11, the second support portion 212 is connected to the second end of the first support portion 211 at an angle, and the second support portion 212 is spaced apart from the first side panel 11 to form an avoidance space 14.

[0043] It can be understood that the first support portion 211 and the second support portion 212 can be structural parts such as L-shaped steel or angle steel. The first end of the first support portion 211 can be connected to the shell body 10 by welding, bolts or clamping. The first support portion 211 can be vertically arranged with the inner wall of the shell body 10, so that the other end of the first support portion 211 extends toward the accommodating space 13. The second support portion 212 can be parallel to and spaced from the inner wall of the shell body 10, and is welded to the first support portion 211. The upper surfaces of the first support portion 211 and the second support portion 212 can support the condenser, and the condenser can be further connected and fixed to the first support member 21 by bolts. One person can place the condenser on the first support member 21 to complete the installation and fixation of the condenser.

[0044] In some embodiments of the present invention, the support assembly 20 further includes a second support member 22 , which is connected to the second side plate 12 , and the first support member 21 and the second support member 22 are spaced apart from each other along the direction from the first side plate 11 toward the second side plate 12 .

[0045] It can be understood that in order to improve the support and fixing strength of the condenser, a plurality of support members can be provided. The second support member 22 can be spaced apart from the first support member 21 in the length direction of the shell body 10, or can be spaced apart from the first support member 21 in the height direction or the width direction. The second support member 22 can be a sheet metal strip structure or a sheet metal block structure, which is fixed to the inner wall of the shell body 10 by welding or bolts. The second support member 22 has an upper surface for supporting the condenser, and the condenser can be directly placed on the first support member 21 and the second support member 22 to complete the installation of the condenser into the unit shell.

[0046] In some embodiments of the present invention, along the height direction of the housing body 10 , the top surface of the second support member 22 is arranged parallel to the top surface of the first support member 21 .

[0047] It can be understood that the top surface of the second support member 22 and the top surface of the first support member 21 jointly support the condenser, and the two top surfaces are arranged in parallel, which can provide better support for the condenser when the bottom end of the condenser is a plane.

[0048] In some embodiments of the present invention, the cross section of the second support member 22 is triangular along the height direction of the shell body 10, so that the structural strength of the second support member 22 is higher to accommodate a heavier condenser.

[0049] In some embodiments of the present invention, a bolt hole 213 is further provided on the first support member 21 , and a bolt passing through the bolt hole 213 can be used to connect one end of the first support member 21 away from the first side plate 11 to the other side plate to improve the structural strength.

[0050] The second aspect of the present invention proposes a thermal management system for energy storage equipment, including an air-cooled unit, the air-cooled unit including a unit shell and a condenser, the unit shell is the unit shell proposed according to the first aspect of the present invention, and the condenser is installed on the support assembly 20.

[0051] The thermal management system proposed in the second aspect of the utility model has the same beneficial effects as the unit housing proposed in the first aspect of the utility model. The energy storage device can be a battery energy storage system, which stores the power generated by the battery and discharges it for use at an appropriate time. The energy storage device will generate heat during operation, so it needs to be thermally managed to reduce the adverse effects of high temperature on the energy storage device. The thermal management system may include an integrated air-cooled air conditioner, that is, an air-cooled unit, which cools the energy storage device by air cooling to thermally manage the energy storage device when the temperature is high. The unit housing is the outer shell of the air-cooled unit. Since the structure of the integrated air-cooled unit is compact and complex, it is inconvenient to install the condenser. The utility model sets a support assembly 20 on the inner side of the unit housing. During installation, the condenser can be directly placed on the support assembly 20 to achieve installation and fixation, which is convenient to operate.

[0052] In some embodiments of the present invention, the condenser includes a condenser housing 30 , and the bottom end of the condenser housing 30 is connected to the support assembly 20 along the height direction of the unit shell.

[0053] It can be understood that the condenser shell 30 can be a cube-shaped and is made by sheet metal technology. The bottom end of the condenser shell 30 is a plane. The bottom end of the condenser shell 30 can be directly in contact with the support assembly 20, and the condenser is placed on the support assembly 20 for installation. The operation is easy and can be completed by one person.

[0054] In some embodiments of the present invention, the thermal management system further includes a fastener 31, a first connection hole is provided on the unit housing, a second connection hole is provided on the condenser housing 30, and the fastener 31 is respectively passed through the first connection hole and the second connection hole.

[0055] It is understandable that the condenser housing 30 can be further fixed to the unit housing by bolts to improve the installation reliability of the condenser.
