Description

Technical Field

[0001] The utility model belongs to the technical field of battery cabinets, and particularly relates to an air duct structure assembly for a power distribution bin of an energy storage battery cabinet. Background Technique

[0002] During the operation of an energy storage battery cabinet, as one of the core components, the inverter will generate a large amount of heat. If effective heat dissipation measures are not taken, it will seriously affect the working performance and service life of the inverter.

[0003] At present, most energy storage battery cabinets use natural cooling or simple forced ventilation for heat dissipation, but these methods often cannot meet the heat dissipation requirements of high-power density inverters, resulting in relatively serious heat generation of the inverter and unable to meet the usage requirements of customers. Summary of the Utility Model

[0004] Aiming at the above deficiencies existing in the prior art, the technical problem to be solved by the utility model is to provide an air duct structure assembly for a power distribution bin of an energy storage battery cabinet.

[0005] The technical solution adopted by the utility model to solve its technical problems is to provide an air duct structure assembly for a power distribution bin of an energy storage battery cabinet, including: a cabinet body configured with a receiving cavity, an air outlet and an air inlet are respectively arranged at the top end and the bottom end of the side wall of the cabinet body, and both the air outlet and the air inlet are communicated with the receiving cavity;

[0006] An inverter is installed in the receiving cavity. The inverter divides the receiving cavity into a first air guide area and a second air guide area. The first air guide area is communicated with the air inlet, the second air guide area is communicated with the air outlet, the gas flowing from the first air guide area to the second air guide area is used to take away the heat generated by the inverter, and the flowing direction of the gas in the receiving cavity is perpendicular to the normal direction of the air outlet or the air inlet;

[0007] An air duct and a cooling fan. One end of the air duct is opened towards the inverter, and the other end is opened towards the air outlet to converge the heat into the air duct; the cooling fan is installed between the air duct and the air outlet to take away the heat in the air duct to the outside of the cabinet body.

[0008] In the above air duct structure assembly for a power distribution bin of an energy storage battery cabinet, an inclined surface is formed on the outer wall of the air duct, a buckle is installed on the inclined surface, a fixing block is arranged on the inner wall of the receiving cavity, a clamping groove is formed in the fixing block, and the buckle is movably clamped in the clamping groove to fix the air duct in the first air guide area.

[0009] In the above-mentioned air duct structure assembly of the power distribution bin of the energy storage battery cabinet, a fixed bracket is connected to the inverter. Connecting parts extend outward from both side walls of the fixed bracket. Load-bearing blocks are arranged on the inner wall of the accommodation cavity. The connecting parts are movably abutted and snapped onto the load-bearing blocks.

[0010] In the above-mentioned air duct structure assembly of the power distribution bin of the energy storage battery cabinet, the air duct is made of sheet metal and is square in shape.

[0011] In the above-mentioned air duct structure assembly of the power distribution bin of the energy storage battery cabinet, flanges arranged in the vertical direction are formed on the connecting parts. Anti-disengagement grooves are formed in the load-bearing blocks. The flanges are movably snapped into the anti-disengagement grooves.

[0012] In the above-mentioned air duct structure assembly of the power distribution bin of the energy storage battery cabinet, a number of inclined air guiding vanes are arranged in both the air outlet and the air inlet.

[0013] In the above-mentioned air duct structure assembly of the power distribution bin of the energy storage battery cabinet, a dust-proof net is connected to the outer wall of the cabinet body. The dust-proof net covers the open ends of the air outlet and the air inlet away from the accommodation cavity.

[0014] Compared with the prior art, the advantage of the present utility model lies in that the gas flow direction in the accommodation cavity is perpendicular to the normal direction of the air outlet or the air inlet. After the heat dissipation fan is turned on, the gas entering the first air guiding area through the air inlet can drive the heat generated by the inverter while converging into the air duct in the second air guiding area, and finally the gas is discharged outside the cabinet through the heat dissipation fan. As a whole, it forms an open rectangular heat dissipation system, which can more efficiently take away the heat dissipated by the inverter and ensure the normal and stable operation of the energy storage battery cabinet.

[0023] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0024] As Figures 1 to 4 shown, a structural assembly of the air duct 3 of the power distribution bin of an energy storage battery cabinet of the present invention includes: a cabinet body 1 configured with a receiving cavity 10, an air outlet 11 and an air inlet 12 are respectively arranged at the top and bottom of the side wall of the cabinet body 1, and both the air outlet 11 and the air inlet 12 are communicated with the receiving cavity 10; an inverter 2 installed in the receiving cavity 10, the inverter 2 divides the receiving cavity 10 into a first air guiding area 13 and a second air guiding area 14, the first air guiding area 13 is communicated with the air inlet 12, the second air guiding area 14 is communicated with the air outlet 11, the gas flowing from the first air guiding area 13 into the second air guiding area 14 is used to take away the heat generated by the inverter 2, and the gas flow direction in the receiving cavity 10 is perpendicular to the normal direction of the air outlet 11 or the air inlet 12; an air duct 3 and a cooling fan 4, one end of the air duct 3 is opened towards the inverter 2, and the other end is opened towards the air outlet 11 to converge the heat into the air duct 3; the cooling fan 4 is installed between the air duct 3 and the air outlet 11 to take away the heat in the air duct 3 to the outside of the cabinet body 1.

[0025] This embodiment is mainly to achieve the heat dissipation of the inverter 2. Specifically, as Figure 1 shown, the air outlet 11 is above the right side wall of the cabinet body 1, and the air inlet 12 is below the right side wall of the cabinet body 1. When the device (i.e., the inverter 2) is running, the cooling fan 4 can be turned on. The external gas can enter the first air guiding area 13 from the air inlet 12 in advance. Because the cooling fan 4 is turned on, it promotes the circulation of the gas in the receiving cavity 10, so that the gas in the first air guiding area 13 flows into the second air guiding area 14. During this process, the gas flow can take away the heat generated by the inverter 2. As the heat converges into the air duct 3 in the second air guiding area 14, it can flow out along the direction of the air outlet 11 under the drive of the cooling fan 4. It should be noted that in this solution, the gas flow direction in the receiving cavity 10 is set perpendicular to the normal direction of the air outlet 11 or the air inlet 12, making the overall an open rectangular heat dissipation system, which can more efficiently take away the heat dissipated by the inverter 2 and ensure the normal and stable operation of the energy storage battery cabinet.

[0026] An inclined surface 30 is formed on the outer wall of the air duct 3, and a buckle 31 is installed on the inclined surface 30. A fixing block 15 is provided on the inner wall of the accommodating cavity 10, and a snap-fit ​​groove 150 is formed in the fixing block 15. The snap-fit ​​groove 150 is movably snapped in the snap-fit ​​groove 150 to fix the air duct 3 in the first air guide area 13.

[0027] like Figure 2 and Figure 3 As shown, the air duct 3 and the cabinet 1 in this solution are connected in a detachable manner, wherein the inclined surface 30 on the outer wall of the air duct 3 provides sufficient space for the workers' field of vision during installation, ensuring that the workers can smoothly engage the buckle 31 in the snap-fit ​​groove 150 to ensure the stability of the air duct 3.

[0028] Preferably, the design of the air duct 3 in this solution controls the direction of the airflow, such as Figure 2 and Figure 3 As shown, the opening at the bottom of the air duct 3 faces the top of the inverter 2, while the side opening faces the cooling fan 4. When the gas in the first air guide area 13 flows into the second air guide area 14, it not only drives the heat generated by the inverter 2, but also can completely gather the gas into the air duct 3, effectively improving the heat dissipation efficiency.

[0029] Preferably, the air duct 3 in this solution is made of sheet metal and is arranged in a square shape, which provides convenience for workers during manufacturing.

[0030] Continue to refer Figure 2 and Figure 3 In this scheme, the air outlet 11 and the air inlet 12 are both provided with a plurality of inclined air guide blades 17, and the directions of the plurality of air guide blades 17 in the air outlet 11 or the air inlet 12 are the same, which can not only play a guiding effect, but also effectively ensure that there will be no turbulence when the gas flows out or in.

[0031] Further, if Figure 3 As shown, the present solution also has a dustproof net 18 connected to the outer wall of the cabinet 1, and the dustproof net 18 covers the opening ends of the air outlet 11 and the air inlet 12 away from the accommodating cavity 10, so that the device can effectively prevent external dust and impurities from entering when performing heat dissipation operations, thereby playing a certain protective effect and extending the service life.

[0032] The inverter 2 is connected to a fixing bracket 20 , and both side walls of the fixing bracket 20 extend outward to form a connecting portion 200 . A load-bearing block 16 is provided on the inner wall of the accommodating cavity 10 , and the connecting portion 200 is movably abutted and the buckle 31 is on the load-bearing block 16 .

[0033] like Figure 1 and Figure 4As shown, during the installation of the inverter 2 in this solution, it is often necessary to use handling tools (such as forklifts) to lift the inverter 2 into the accommodation cavity 10. Before that, workers can pre-install the fixing bracket 20 on the inverter 2, so that when the inverter 2 is sent into the accommodation cavity 10, it can abut against the load-bearing block 16 through the connecting part 200, replacing the handling tool to provide a certain supporting effect for the inverter 2. At the same time, the movable buckle 31 between the connecting part 200 and the load-bearing block 16 plays a certain limiting effect, ensuring that without the support of the handling tool, workers can use screws to connect the connecting part 200 to the cabinet body 1. The overall operation is simple, bringing convenience for on-site installation by employees or customers.

[0034] A flanging 200a is formed on the connecting part 200 and is arranged in the vertical direction. An anti-disengagement groove 160 is formed in the load-bearing block 16, and the flanging 200a and the movable buckle 31 are in the anti-disengagement groove 160.

[0035] Furthermore, as Figure 4 shown, when the above-mentioned inverter 2 is transferred into the accommodation cavity 10 by the handling tool, at this time, the connecting part 200 is above the load-bearing block 16. As the handling tool lowers the inverter 2, the connecting part 200 can abut against the load-bearing block 16 while inserting the flanging 200a into the anti-disengagement groove 160, thus enabling workers to perform screw tightening operations. It should be noted that the load-bearing block 16 can be integrally die-cast with the cabinet body 1, which can bear the weight of the inverter 2 and is safer and more reliable.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, the directional indicators will also change accordingly.

[0037] In addition, in the present invention, descriptions such as "first", "second", and "one" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0038] In the present utility model, unless otherwise clearly stipulated and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model may be understood according to specific circumstances.

[0039] In addition, the technical solutions between various embodiments of the present utility model may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
