Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a cabinet for an integrated energy storage converter. Background Technology

[0002] With the rapid development of energy storage technology, the demand for compact, high-power-density energy storage converters is increasing. The converter cabinet integrates a large number of heat-generating electronic components, and high heat can affect the normal operation and lifespan of these components. Therefore, heat dissipation is a crucial consideration when using converters. Traditional heat dissipation methods typically involve creating ventilation holes on the side walls of the cabinet. While this method can dissipate heat, the amount of heat dissipation is limited, and the airflow is not smooth. This is especially true for outdoor converters, where the number and area of ​​ventilation holes are limited due to the need for rain protection, thus restricting the effectiveness of heat dissipation. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a cabinet for an integrated energy storage converter.

[0004] The technical solution of this utility model is as follows: A cabinet for an integrated energy storage converter includes a housing, a cabinet top located above the housing, and a cabinet bottom located below the housing. A heat dissipation vent is provided between the top of the front and rear side walls of the housing and the bottom of the cabinet top. A mounting plate is vertically installed inside the housing, and a vertically extending cooling channel is provided inside the mounting plate. The cabinet top is a cavity structure extending to the left and right, with a rhomboid cross section. The middle of the bottom wall of the cabinet top is connected to the top of the cooling channel. A water collection tank is provided on the front and / or rear side of the cabinet top, and a water inlet is provided at the corresponding position of the water collection tank. The water collection tank is connected to the internal cavity of the cabinet top through the water inlet, and the water in it can flow into the cabinet top through the water inlet. Multiple auxiliary heat dissipation holes are opened on the bottom wall of the cabinet top, and water-blocking parts protrude from the edge of the auxiliary heat dissipation holes in the cavity of the cabinet top. The bottom of the cabinet is equipped with a drainage channel that connects to the bottom of the cooling channel.

[0005] Furthermore, the water-blocking part is a tubular structure.

[0006] Furthermore, the height of the water inlet is lower than the protrusion height of the water-blocking part.

[0007] Furthermore, the top of the water-retaining part bends and extends towards the middle of the bottom wall of the cabinet top.

[0008] Furthermore, the auxiliary heat dissipation holes are concentrated on the front and rear sides of the bottom wall near the top of the cabinet.

[0009] Furthermore, water collection troughs are provided on both the front and back sides of the top of the cabinet.

[0010] Furthermore, the water collection trough protrudes outward from the front and rear sides of the top of the cabinet.

[0011] Furthermore, the bottom surface of the water collection tank is a sloping surface that slopes downwards from the inside out.

[0012] Furthermore, a filter screen is installed at the water inlet. Furthermore, the drainage channel extends downwards from the connection point with the cooling channel towards the front and rear sides of the cabinet bottom.

[0013] This utility model provides a cabinet for an integrated energy storage converter. When it rains, rainwater is channeled into the cooling channels of the mounting plate to directly remove heat from the core heat-generating components. When it is not raining, an additional heat dissipation channel is provided through the connection between the water inlet, the inner cavity of the cabinet top, and the auxiliary heat dissipation holes. This structural design improves the heat dissipation efficiency of the cabinet and more effectively meets the heat dissipation requirements of integrated converters. Attached Figure Description

[0016] This utility model embodiment provides a cabinet for an integrated energy storage converter. The cabinet is mainly used as a cabinet for outdoor converters and utilizes natural rainwater and rainwater channels to improve heat dissipation efficiency.

[0017] like Figure 1 As shown, the cabinet of this utility model includes a box body 1, a cabinet top 2 located above the box body 1, and a cabinet bottom 3 located below the box body 1. The box body 1 constitutes the main body of the cabinet, and its internal space is used to install various electronic components of the energy storage converter, such as power modules, control boards, reactors, and other heat-generating components.

[0018] A ventilation opening 11 is provided between the top of the front and rear side walls of the cabinet 1 and the bottom of the cabinet top 2. This ventilation opening 11 extends along the left-right direction (i.e., the length direction of the cabinet) and is elongated. The width of the ventilation opening 11 can be designed according to the heat dissipation requirements, typically within the range of 5-15 cm, allowing hot air inside the cabinet 1 to escape smoothly. The ventilation opening 11 can be equipped with a mesh panel or designed as a grille to prevent birds from entering.

[0019] A mounting plate 12 is vertically installed inside the housing 1. This mounting plate 12 is preferably made of a metal material with good thermal conductivity, such as aluminum alloy or stainless steel. The mounting plate 12 is fixed inside the housing 1 by a detachable connection method (e.g., bolt connection). The front and rear surfaces of the mounting plate 12 are used to mount various electronic components of the converter. Specifically, vertically extending cooling channels 121 are pre-embedded or machined inside the mounting plate 12. Multiple cooling channels 121 are preferably provided, evenly spaced side-by-side, and their number can be determined according to heat dissipation requirements, typically 4-8. The cooling channels 121 are preferably circular pipes, each extending from the top to the bottom of the mounting plate 12, forming a continuous liquid flow path.

[0020] The cabinet top 2 is a cavity structure extending in the left-right direction, with a rhomboid cross-sectional shape. Specifically, the cabinet top 2 has an inverted V-shaped top plate and a regular V-shaped bottom plate. The edges of the two inclined plates of the top and bottom plates meet at the front and rear sides of the cabinet, forming a rhomboid hollow cavity. This rhomboid cross-section design not only provides rain protection for the cabinet 1 through the inverted V-shaped top plate, but also works with the water collection trough 21 to collect rainwater (described in detail later). Furthermore, the regular V-shaped bottom plate guides the hot air inside the cabinet 1 towards the heat dissipation vent 11.

[0021] The middle of the bottom wall (i.e., the bottom plate) of the cabinet top 2, at the intersection of the two inclined bottom walls, is connected to the top of the cooling channel 121 of the mounting plate 12. In this embodiment, a downward connecting pipe is provided in the middle of the bottom wall of the cabinet top 2. This connecting pipe is connected to the top inlet of the cooling channel 121 of the mounting plate 12 by means of flange connection or sealing ring crimping. The connection is sealed to prevent rainwater leakage.

[0022] A water collection trough 21 is provided on the front and / or rear sides of the cabinet top 2 to collect rainwater flowing down from the top plate of the cabinet top 2. A water inlet 22 is provided on the cabinet top 2 corresponding to the water collection trough 21, so that the water collection trough 21 is connected to the internal cavity of the cabinet top 2. The water inlet 22 is located on the side of the water collection trough 21, and the rainwater in the water collection trough 21 can flow into the cabinet top 2 through the water inlet 22, and then into the cooling channel 121 of the mounting plate 12.

[0023] In this embodiment, water collection troughs 21 are provided on both the front and rear sides of the cabinet top 2. The water collection troughs 21 protrude outwards from the front and rear sides of the cabinet top 2, forming outwardly extending water-receiving containers. The cross-section of the water collection troughs 21 can be U-shaped or V-shaped. Rainwater flowing down from the top plate of the cabinet top 2 will enter the water collection troughs 21. Specifically, the bottom surface of the water collection troughs 21 is designed as a downward sloping surface from the inside out. That is, the bottom surface of the water collection troughs 21 gradually decreases from the side closest to the cabinet side wall to the side furthest from the cabinet side wall. This sloping design acts as an "eaves," preventing rainwater from flowing into the cabinet 1 along the outer walls of the water collection troughs 21 and the bottom plate.

[0024] A removable filter screen can be installed at the water inlet 22. The filter screen is used to effectively filter out debris such as leaves and branches without affecting the water flow.

[0025] Multiple auxiliary heat dissipation holes 23 are provided on the bottom wall of the cabinet top 2 (i.e., the two lower sloping surfaces of the rhombus). These auxiliary heat dissipation holes 23 are preferably concentrated on the front and rear sides of the bottom wall of the cabinet top 2, that is, in the area on the sloping bottom wall relatively close to the heat dissipation vent 11. This is to shorten the distance between the auxiliary heat dissipation holes 23 and the water inlet 22, making it easier for hot air to escape, and to reduce the probability of water accidentally accumulating in the middle of the bottom wall of the cabinet top 2, causing water to enter the cabinet 1 through the auxiliary heat dissipation holes 23. The auxiliary heat dissipation holes 23 are evenly distributed in an array.

[0026] The edge of each auxiliary heat dissipation hole 23 protrudes into the cavity of the cabinet top 2 to form a water-blocking part 24. In this embodiment, the water-blocking part 24 is a tubular structure.

[0027] To prevent rainwater entering the cabinet top 2 from overflowing the water baffle 24, the height dimension (i.e., vertical width dimension) of the water inlet 22 is designed to be lower than the protrusion height of the water baffle 24. This height difference ensures that the water level of the rainwater entering the cabinet top 2 cavity will not exceed the height of the pipe opening of the water baffle 24, thereby preventing rainwater from overflowing from the auxiliary heat dissipation hole 23.

[0028] In this embodiment, the top of the water-blocking part 24 is further bent and extended towards the middle of the bottom wall of the cabinet top 2 to form a water-blocking eave, further preventing rainwater from entering the auxiliary heat dissipation hole 23. The bending angle is preferably 30-60 degrees.

[0029] The top plate of the cabinet top 2 is designed to be detachable, and it can be fixed and removed with screws to facilitate cleaning of the cavity. The cabinet top 2 is detachably connected to the housing 1 by flanges and bolts, and a waterproof sealing strip is provided at the connection to facilitate the docking and installation of the cabinet top 2 with the cooling channel 121 on the mounting plate 12.

[0030] A drainage channel 31 is provided on the bottom of the cabinet 3, which is connected to the bottom outlet of the cooling channel 121 of the mounting plate 12. The drainage channel 31 starts from the connection with the cooling channel 121 and extends downwards towards the front and rear sides of the bottom of the cabinet 3. A mesh panel is provided at the outlet of the drainage channel 31 to prevent small animals from entering.

[0031] The cabinet provided by this utility model allows hot air inside the cabinet 1 to rise naturally when there is no rain. Part of the air flows upward along the sloping bottom wall of the cabinet top 2 and is eventually discharged from the heat dissipation vent 11. The other part enters the cavity of the cabinet top 2 through the auxiliary heat dissipation holes 23 and then exits from the water inlet 22. When the hot air rises and flows out of the water inlet 22 inside the cabinet top 2 cavity, it creates a negative pressure within the cavity. This pressure draws cool air from the lower part of the cabinet bottom 3 into the cooling channel 121 through the drainage channel 31, carrying away heat from the mounting plate 12 and enhancing heat dissipation efficiency and effect.

[0032] In rainy conditions, rainwater flows into the collection tank 21, then enters the cabinet top 2 through the inlet 22, and flows downwards along the sloping bottom wall of the cabinet top 2 into the cooling channel 121. As the rainwater flows downwards within the cooling channel 121, it undergoes thorough heat exchange with the heated mounting plate 12, directly cooling the mounting plate 12 and the electronic components mounted on it. The heat-absorbing rainwater continues to flow downwards and is discharged outside the cabinet through the drainage channel 31 at the bottom 3. Using water for heat dissipation, compared to air-only heat dissipation, improves the heat dissipation effect, and utilizes natural rainwater, making it energy-saving and environmentally friendly.
