Description

Technical Field

[0001] This utility model relates to the technical field of energy storage boxes, specifically an energy storage converter cabinet compatible with wall-mounted energy storage boxes. Background Technology

[0002] Household wall-mounted energy storage boxes are typically used as standalone low-power energy storage devices for home use. However, for most households, the utilization rate of wall-mounted energy storage boxes is low. To improve the utilization rate of wall-mounted energy storage boxes, it is considered to form a comprehensive energy storage system based on multiple low-power wall-mounted energy storage boxes in parallel. This can meet the low-power needs of home use while also meeting the needs of industrial high-power energy storage. However, directly connecting each wall-mounted energy storage box in parallel would occupy a large space. Therefore, the method of using wall-mounted devices to concentrate multiple wall-mounted energy storage boxes in the same cabinet to form an energy storage converter cabinet is becoming more popular.

[0003] According to Chinese Patent No. CN217241215U, an energy storage converter cabinet compatible with wall-mounted energy storage boxes includes a front-opening cabinet, multiple wall-mounted energy storage boxes, a power module, and a cooling fan. A cooling vent is located at the top of the rear wall of the cabinet. Multiple wall-mounted energy storage boxes are spaced vertically within the cabinet, with the rear ends of each box forming a cooling duct with the rear wall of the cabinet. Hot air exits from the rear ends of the wall-mounted energy storage boxes towards the cooling duct. The power module is located within the cabinet, below the lowest wall-mounted energy storage box. The cooling fan is located within the cabinet, directly in front of the power module, and blows air towards the power module, creating an upward airflow within the cooling duct. This airflow carries the hot air exiting from each wall-mounted energy storage box through the cooling vent.

[0004] In the above solution, the internal heat dissipation of the cabinet is achieved by exhaust fans and cooling fans, and the gap between the rear ends of two adjacent wall-mounted energy storage boxes is sealed by a sealing plate. This results in the following disadvantages: when the energy storage converter cabinet is in use, the area between each pair of adjacent wall-mounted energy storage boxes is blocked, causing heat to accumulate in these areas, which reduces the overall heat dissipation efficiency and service life. Utility Model Content

[0005] The purpose of this invention is to provide an energy storage converter cabinet compatible with wall-mounted energy storage boxes, in order to solve the problem that when the energy storage converter cabinet is in use, the area between each two adjacent wall-mounted energy storage boxes is blocked, causing heat to accumulate in these areas, which reduces the overall heat dissipation efficiency and service life.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an energy storage converter cabinet compatible with wall-mounted energy storage boxes, comprising a cabinet body, an air inlet on the right side of the outer wall of the cabinet body, a heat dissipation vent on the left side of the outer wall of the cabinet body, a PLC controller fixed on the front side of the outer wall of the cabinet body, a heat dissipation fan fixed inside the air inlet, the heat dissipation fan being electrically connected to the PLC controller, an exhaust fan fixed inside the heat dissipation vent, the exhaust fan being electrically connected to the PLC controller, a plurality of wall-mounted energy storage boxes fixed inside the cabinet body, a plurality of connecting frames fixed inside the cabinet body, the plurality of connecting frames being spaced apart from the plurality of wall-mounted energy storage boxes, a fixing groove being formed on the bottom surface of the inner wall of the cabinet body, a power module being fixed inside the fixing groove, the connecting frames forming a heat dissipation duct with the left side of the inner wall of the cabinet body, a diverter plate being fixed on the bottom surface of the lower wall-mounted energy storage box, and guide plates being fixed on the top surfaces of the two lower wall-mounted energy storage boxes respectively, with a plurality of through holes on one side of each of the two guide plates.

[0007] Preferably, an arc-shaped drainage plate is fixed to the left side of each of the connecting frames.

[0008] Preferably, a fixing hole is provided on the front side of the outer wall of the cabinet, and a temperature sensor is fixed inside the fixing hole. The temperature sensor is electrically connected to the PLC controller.

[0009] Preferably, a mounting frame is detachably provided on the right side of the outer wall of the cabinet, and a dustproof net is fixed inside the mounting frame.

[0010] Preferably, two connecting slots are provided on the right side of the outer wall of the cabinet, and a first magnet is fixed inside each of the two connecting slots. A second magnet is fixed on the front and rear sides of the outer wall of the mounting frame, and the two second magnets are magnetically attracted to the two first magnets respectively.

[0011] Preferably, the thickness of the dustproof net is 2cm.

[0012] Compared with existing technologies, an energy storage converter cabinet compatible with wall-mounted energy storage boxes, which adopts the above technical solution, has the following beneficial effects:

[0013] First, during use, the cooling fan and exhaust fan can dissipate heat from the inside of the cabinet. Then, the connecting frame, cooling duct, diversion plate and guide plate can divide and guide the airflow, which helps to dissipate the heat in the area between each two adjacent wall-mounted energy storage boxes, and helps to prevent heat accumulation, thereby improving the overall heat dissipation efficiency and service life.

[0014] Second, during use, the arc-shaped airflow guide plate effectively directs the hot air from the heat dissipation duct and between two adjacent wall-mounted energy storage boxes upwards, avoiding airflow turbulence and stagnation inside the cabinet and further improving heat dissipation efficiency. A temperature sensor allows for real-time monitoring of the cabinet's internal temperature. When the temperature exceeds a preset value, the temperature sensor transmits a signal to the PLC controller. The PLC controller automatically adjusts the speed of the cooling fan and exhaust fan based on the received signal to achieve optimal heat dissipation.

[0015] Thirdly, during use, the mounting frame and dustproof net effectively prevent dust and impurities from entering the cabinet, ensuring the cleanliness and efficient operation of the heat dissipation system. The first and second magnets facilitate easy assembly and disassembly of the mounting frame and dustproof net, making assembly and disassembly simpler and more convenient, improving efficiency and saving time and effort. The dustproof net is 2cm thick, ensuring sufficient dust protection while avoiding increased airflow resistance due to excessive thickness. This thickness effectively blocks dust and impurities while maintaining unobstructed airflow. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, an energy storage converter cabinet compatible with wall-mounted energy storage boxes includes a cabinet body 1. An air inlet 2 is located on the right side of the outer wall of the cabinet body 1, and a heat dissipation vent 3 is located on the left side of the outer wall of the cabinet body 1. A PLC controller is fixed to the front of the outer wall of the cabinet body 1. A cooling fan 4 is fixed inside the air inlet 2 and is electrically connected to the PLC controller. An exhaust fan 5 is fixed inside the heat dissipation vent 3 and is electrically connected to the PLC controller. Several wall-mounted energy storage boxes 6 are fixed inside the cabinet body 1. The cabinet 1 has several connecting brackets 7 fixed inside, and the connecting brackets 7 are arranged at intervals between several wall-mounted energy storage boxes 6. The bottom surface of the cabinet 1 has a fixing groove 8, and the power module 9 is fixed inside the fixing groove 8. The connecting brackets 7 and the left side of the inner wall of the cabinet 1 form a heat dissipation air duct 10. The bottom surface of the wall-mounted energy storage box 6 below is fixed with a diverter plate 11, and the top surfaces of the two wall-mounted energy storage boxes 6 below are respectively fixed with guide plates 12. Several through holes 13 are opened on one side of the two guide plates 12.

[0023] During use, when the heat inside the cabinet 1 accumulates to a certain level, the cooling fan 4 is activated to blow air into the interior of the cabinet 1. At this time, the airflow entering from the outside can be divided by the diversion plate 11, causing the airflow to split into two. One airflow blows directly onto the power module 9 to directly dissipate heat. Then, this airflow rises along the cooling duct 10 to provide secondary cooling to the left side of the wall-mounted energy storage box 6. The other airflow rises to the right side of the wall-mounted energy storage box 6 to dissipate heat. At this time, the upward airflow passes through the guide plate 12, allowing some airflow to penetrate through the through hole 13 into the space between two adjacent wall-mounted energy storage boxes 6, effectively dissipating the heat in these areas. The other part flows upward along the top of the guide plate 12, which can dissipate heat between each pair of adjacent wall-mounted energy storage boxes 6. Then, the exhaust fan 5 is activated to exhaust the two hot airflows.

[0024] The cooling fan 4 and exhaust fan 5 can dissipate heat from the inside of the cabinet 1. The airflow is then divided and guided by the connecting frame 7, cooling duct 10, diverter plate 11 and guide plate 12, which helps to dissipate the heat in the area between each two adjacent wall-mounted energy storage boxes 6 and prevent heat accumulation, thereby improving the overall heat dissipation efficiency and service life.

[0025] like Figure 2 and Figure 3 As shown, several connecting frames 7 are respectively fixed with arc-shaped diversion plates 14 on their left sides.

[0026] During use, the arc-shaped air intake plate 14 effectively guides the hot air between the heat dissipation duct 10 and the two adjacent wall-mounted energy storage boxes 6 to flow upward, avoiding airflow disturbance and stagnation inside the cabinet 1, and further improving heat dissipation efficiency.

[0027] like Figure 1 , Figure 2and Figure 4 As shown, a fixing hole 15 is provided on the front side of the outer wall of the cabinet 1. A temperature sensor 16 is fixed inside the fixing hole 15. The temperature sensor 16 is electrically connected to the PLC controller. A mounting frame 17 is detachably provided on the right side of the outer wall of the cabinet 1. A dustproof net 18 is fixed inside the mounting frame 17.

[0028] During use, the temperature sensor 16 facilitates real-time monitoring of the temperature inside the cabinet 1. When the temperature exceeds the preset value, the temperature sensor 16 transmits a signal to the PLC controller. The PLC controller automatically adjusts the speed of the cooling fan 4 and the exhaust fan 5 based on the received signal to achieve the best heat dissipation effect. The mounting frame 17 and dustproof net 18 effectively prevent dust and impurities in the air from entering the cabinet 1, ensuring the cleanliness and efficient operation of the heat dissipation system.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, two connecting slots 19 are opened on the right side of the outer wall of the cabinet 1. The first magnet 20 is fixed inside the two connecting slots 19 respectively. The second magnet 21 is fixed on the front and rear sides of the outer wall of the mounting frame 17 respectively. The two second magnets 21 are magnetically attracted to the two first magnets 20 respectively. The thickness of the dustproof net 18 is 2cm.

[0030] During use, the first magnet 20 and the second magnet 21 facilitate the assembly and disassembly of the mounting frame 17 and the dustproof net 18, making assembly and disassembly simpler and more convenient, improving efficiency, and saving time and effort. The thickness of the dustproof net 18 is set at 2cm, which ensures sufficient dustproof effect while avoiding increased airflow resistance due to excessive thickness. This thickness of dustproof net 18 can effectively block dust and impurities while maintaining unobstructed airflow.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
