DETAILED DESCRIPTION

[0026] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0027] like Figure 1-Figure 7 As shown, the PCS installation structure provided in this embodiment is installed on the top of the energy storage cabinet body 5. The PCS installation structure includes: a support member 1 and a fastener 2 for forming a clamping space 21. The clamping space 21 is located on the top of the energy storage cabinet body 5, and an energy storage inverter 3 is installed therein. The clamping space 21 can fix the position of the energy storage inverter 3.

[0028] The front end of the clamping space 21 is provided with an air outlet component 4, which includes a first channel 401, which is used to receive the airflow from the direction of the energy storage converter 3 and guide it out of the energy storage cabinet body 5. Here, external cold air can be blown toward the energy storage converter 3, so that the hot air generated by the energy storage converter 3 is guided out from the first channel 401.

[0029] As an independent ventilation structure, the air outlet component 4 is mainly responsible for effectively directing the hot air flow outward from the energy storage inverter 3, ensuring that the air flow around the energy storage inverter 3 can flow in a preset direction, thereby helping to dissipate the heat generated by the energy storage inverter 3 during operation.

[0030] In this embodiment, two support members 1 are provided and are distributed at opposite positions. The fastener 2 and the two support members 1 are enclosed together to form the above-mentioned clamping space 21 .

[0031] The energy storage inverter 3 is placed on two support parts 102 and pressed by the fastener 2 at the same time. This fixing method can effectively fix the position of the energy storage inverter 3, and it is also convenient to disassemble and assemble the energy storage inverter 3 when needed, which is beneficial to the subsequent maintenance and repair of the energy storage inverter 3 separately, and will not affect the normal operation of other components inside the energy storage cabinet body 5.

[0032] In this embodiment, the support member 1 includes: a fixing portion 101 , a supporting portion 102 disposed on the top of the fixing portion 101 , and the energy storage converter 3 is mounted on the supporting portion 102 .

[0033] The fixing part 101 is installed on the top of the energy storage cabinet body 5 . The main function of the fixing part 101 is to fix the energy storage cabinet body 5 while supporting the supporting part 102 , so that there is space between the supporting part 102 and the energy storage cabinet body 5 .

[0034] There is space between the support portion 102 and the energy storage cabinet body 5, which can ensure that when the energy storage inverter 3 is installed on the support portion 102, there is also space between its bottom surface and the top of the energy storage cabinet body 5, which is conducive to air circulation, thereby facilitating the heat dissipation of the energy storage inverter 3. At the same time, with the assistance of the air outlet component 4, the heat dissipation effect of the energy storage inverter 3 is better.

[0035] In this embodiment, the support portion 102 includes: a bottom plate 1021 and a side plate 1022 which are vertically connected to each other, wherein the bottom plate 1021 holds up the energy storage converter 3 and the side plate 1022 limits the energy storage converter 3 in the horizontal direction.

[0036] The two side plates 1022 are respectively connected and fixed to the corresponding ends of the fasteners 2 to clamp and fix the energy storage converter 3 to ensure that the movement of the energy storage converter 3 is completely restricted.

[0037] In this embodiment, the fastener 2 includes: a connecting horizontal piece 203 , and opposite ends of the connecting horizontal piece 203 are respectively provided with a first vertical piece 201 and a second vertical piece 202 , and the first vertical piece 201 and the second vertical piece 202 are oppositely distributed and parallel to each other.

[0038] The first vertical piece 201 and the second vertical piece 202 are arranged vertically, and the connecting cross piece 203 is arranged horizontally. The first vertical piece 201 is connected and fixed to one side plate 1022, and the second vertical piece 202 is connected and fixed to the other side plate 1022, thereby forming a clamping space 21.

[0039] In this embodiment, the first vertical piece 201, the second vertical piece 2 and the connecting horizontal piece 203 are all rod-shaped structures, that is, the fastener 2 is relatively narrow as a whole. While being able to effectively clamp the energy storage inverter, it will not fit too much with the surface of the energy storage inverter 3, which is beneficial to the heat dissipation of the energy storage inverter 3.

[0040] In this embodiment, an inlet 402 and an outlet 403 are respectively provided at opposite ends of the air outlet assembly 4 , wherein the inlet 402 faces the energy storage converter 3 located in the clamping space 21 , and the outlet 403 faces the outside of the energy storage cabinet body 5 .

[0041] The caliber of the outlet 403 is larger than that of the inlet 402 , and the inlet 402 and the outlet 403 are connected through the first channel 401 , forming an airflow derivation structure from small to large, thereby optimizing the airflow guidance around the energy storage converter 3 .

[0042] The inlet 402 is arranged toward the energy storage inverter 3 so that after the external cold air flows along the energy storage inverter 3, it can directly carry the hot air to flow out of the energy storage cabinet body 5 through the airflow derivation structure composed of the inlet 402, the first channel 401 and the outlet 403. This design helps the cold air (airflow) to more smoothly leave the energy storage cabinet body 5 through the enlarged outlet 403 after absorbing heat through the energy storage inverter 3. The airflow path design from small to large can reduce the resistance of the airflow, so that the hot air can be discharged out of the energy storage cabinet body 5 more quickly, thereby improving the heat dissipation efficiency.

[0043] In this embodiment, the air outlet assembly 4 is an integrally formed shell structure, and the opposite ends of the shell 4 are connected to form a first channel 401, and the opposite ends of the first channel 401 are respectively defined as an inlet 402 and an outlet 403. The shell 4 is divided into a first shell part 41 and a second shell part 42 according to its length direction, the inlet 402 is provided at one end of the first shell part 41 close to the energy storage converter 3, and the outlet 403 is provided at one end of the second shell part 42 away from the energy storage converter 3.

[0044] The bottom surface of the first shell portion 41 is horizontal and higher than the bottom surface of the second shell portion 42 . A cable accommodating space is reserved between the bottom surface of the first shell portion 41 and the top surface of the mounting panel 6 . The cable accommodating space is the second channel 404 .

[0045] The horizontal design of the bottom surface of the first part 41 of the shell not only takes into account the small-diameter design of the inlet 402, but also takes into account the management of cables.

[0046] In this embodiment, an energy storage cabinet is further provided. The energy storage cabinet includes: an energy storage cabinet body 5 , and a PCS installation structure installed on the top of the energy storage cabinet body 5 .

[0047] Among them, the air outlet component 4 and the clamping space 21 of the PCS installation structure are arranged in a front-to-back manner, and an installation panel 6 is arranged between the PCS installation structure and the energy storage cabinet body 5. A top cover 7 is hinged on one side of the installation panel 6. The top cover 7 is used to cover the installation panel 6 and the PCS installation structure thereon to protect the PCS installation structure.

[0048] During the assembly process of the energy storage cabinet, the PCS installation structure can be fixed on the installation panel 6, and then the installation panel 6 can be installed on the top of the energy storage cabinet body 5. In this way, there is no need to apply too many steps on the top of the energy storage cabinet body 5, which can simplify the assembly process of the energy storage cabinet.

[0049] The clamping space 21 enclosed by the support 1 and the fastener 2 is responsible for fixing the energy storage inverter 3 on the top of the energy storage cabinet body 5, ensuring that it will not produce relative displacement relative to the energy storage cabinet body 5 or other components when the energy storage cabinet is used or transported, thereby ensuring the reliability of the energy storage cabinet.

[0050] The energy storage converter 3 is fixed on the top of the energy storage cabinet body 5 by the clamping space 21 , which not only solves the stability problem of the installation of the energy storage converter 3 , but also provides a spatial layout for the air outlet component 4 to optimize the heat dissipation of the energy storage converter 3 .

[0051] In this embodiment, a cable outlet hole 502 is formed through the top surface of the energy storage cabinet body 5, and cables on the energy storage cabinet body 5 can extend outward or inward through the cable outlet hole 502. After the cables of the energy storage batteries in the energy storage cabinet body 5 extend outward from the cable outlet hole 502, they can be connected to the energy storage converter 3 on the top of the energy storage cabinet body 5 to realize the conversion and storage of electric energy.

[0052] In this embodiment, the support member 1, the fastener 2, the air outlet assembly 4 and the energy storage inverter 3 in the clamping space 21 work together to ensure better thermal management on the top of the energy storage cabinet body 5 through optimized spatial layout and airflow derivation path, thereby ensuring stable and safe operation of the energy storage system.

[0053] In this embodiment, a driving assembly 8 is provided between the installation panel 6 and the top cover 7 , and the driving assembly 8 can control the opening and closing of the top cover 7 on the installation panel 6 .

[0054] In this embodiment, the driving assembly 8 is a gas spring. The gas spring is used mainly to facilitate the control of the flipping of the top cover 7 to improve safety and convenience during maintenance.

[0055] In this embodiment, the partition design of the air outlet component 4 not only optimizes the air circulation, but also integrates the cable management function. Such a design fully considers the effective use of space, so that the second channel 404 can provide a layout path for the cables on the top of the energy storage cabinet body 5 without affecting the main heat dissipation function of the air outlet component 4.

[0056] Through this partition design, the air outlet assembly 4 not only realizes effective heat dissipation of the energy storage converter 3, but also optimizes the use of the top space of the energy storage cabinet body 5, avoiding additional structural complexity that may be introduced due to cable layout.

[0057] In this embodiment, the cables inside and outside the energy storage cabinet body 5 can extend outward or inward through the cable channel 701 on the top cover 7 .

[0058] In this embodiment, a cavity 501 is provided inside the energy storage cabinet body 5. A refrigeration assembly 9 is provided outside the energy storage cabinet body 5, and the refrigeration assembly 9 is used to deliver cooling gas to the cavity 501 to cool the energy storage battery and other components in the cavity 501.

[0059] A ventilation component 10 is provided at the top of the cavity 501, and the ventilation component 10 is used to absorb the hot air in the cavity 501 and transport it to the refrigeration component 9, so that the refrigeration component 9 converts the hot air into cold air and then blows it into the cavity 501, thereby cooling the energy storage battery and other components in the cavity 501.

[0060] In this embodiment, two cavities 501 are provided, and they are arranged adjacent to each other. A ventilation assembly 10 is provided on the top of each cavity 501, and the ventilation assembly 10 includes: an air outlet shell 1001, and an exhaust fan 1002 is provided at the inlet of the air outlet shell 1001. Each cavity is exhausted independently without affecting each other, so as to meet the needs of different users and application scenarios.

[0061] In this embodiment, a plurality of ventilation and dust prevention components 11 are provided on the top of the energy storage cabinet body 5, and the plurality of ventilation and dust prevention components 11 are respectively arranged on the front and rear sides of the PCS installation structure.

[0062] In this embodiment, the ventilation and dust prevention component 11 can be a shutter, which can effectively block the entry of floating objects from the external environment while not affecting the ventilation effect of the air outlet component 4.

[0063] In summary, in this embodiment, the design of the air outlet assembly 4 provided in this embodiment optimizes the air flow path around the energy storage inverter 3, and directly guides the airflow from the energy storage inverter 3 to the outside of the energy storage cabinet body 4 through the first channel and with the help of external cold air, thereby enhancing the heat dissipation effect. At the same time, the design of the support member 1 and the fastener 2 ensures that there is enough space between the energy storage inverter 3 and the top of the energy storage cabinet body 5, which promotes air circulation and further improves the heat dissipation efficiency.

[0064] The PCS installation structure provided in this embodiment is installed on the top of the energy storage cabinet body, thereby improving the utilization rate of the space inside the energy storage cabinet body 5.

[0065] This embodiment improves the stability and reliability of the energy storage cabinet during transportation and use by optimizing the heat dissipation design and structural stability (such as the fixing method of the energy storage converter 3). Effective heat dissipation management also helps to extend the service life of key components such as the energy storage converter 3.

[0066] The design of the mounting panel 6 and the top cover 7 provided in this embodiment not only facilitates the integration and protection of the components, but also enables the energy storage cabinet to be quickly adjusted according to different configuration requirements.
