Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to an energy storage converter. Background Technology

[0002] Energy storage converters mainly consist of components such as gold-film capacitor boards, power boards, and inductors. Because energy storage converters generate significant heat internally, water-cooled heat sinks are required for heat dissipation. Existing energy storage converters typically have their internal components laid flat, with inductors located on the outside. This results in a less compact overall structure, larger size, and lower power density. Due to the flat component layout, larger water-cooled heat sinks are needed to achieve better heat dissipation, leading to higher costs and further increasing the size of the energy storage converter.

[0003] Therefore, there is an urgent need to develop an energy storage converter that is compact in structure, small in size, has high power density, and good heat dissipation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an energy storage converter with a compact structure, small size, high power density, and good heat dissipation, thereby solving the above-mentioned technical problems.

The power distribution components are disposed at the front left of the base plate, the detection plate is disposed at the front right of the base plate, the water-cooled plate is horizontally disposed at the rear of the base plate, the power board and the inverter inductor are attached adjacent to each other on the water-cooled plate, the gold film capacitor plate is attached to the power board, a first horizontal partition is disposed above the gold film capacitor plate, a second horizontal partition is disposed above the detection plate, the energy storage converter also includes a first support device supporting the first horizontal partition and a second support device supporting the second horizontal partition, the electrolytic capacitor plate is disposed on the first horizontal partition, and the relay plate is disposed on the second horizontal partition.

[0011] Preferably, a turbulence fan is provided on one side of the aforementioned water-cooled radiator.

[0012] Preferably, an aerosol fire extinguisher is provided between the detection board and the inverter inductor.

[0015] Power distribution devices are components used to control, protect, and distribute electrical energy. They can be circuit breakers, disconnect switches, contactors, relays, fuses, etc., and can ensure the safe, reliable, and efficient transmission of electrical energy.

[0016] This utility model discloses an energy storage converter. An external DC power supply is connected to a power distribution device, which is electrically connected to a gold-film capacitor board via cables or busbars. The gold-film capacitor board is electrically connected to a power board, which is electrically connected to an inverter inductor via busbars. The inverter inductor is connected to a relay board via busbars. The electrolytic capacitor board is electrically connected to other components, primarily for storing energy and providing large-capacity charge, while also performing multiple functions such as filtering, decoupling, energy storage, and coupling. The detection board is mainly used to detect parameters such as current, voltage, and communication status of other components.

[0017] External DC power enters the gold film capacitor board through the power distribution device, and the gold film capacitor board provides the instantaneous large current required for DC commutation; then it flows from the gold film capacitor board into the power board, where the power board performs AC-DC power conversion; finally, it flows from the power board into the inverter inductor and relay board, where the inverter inductor and relay board achieve LCL filtering output.

[0018] This utility model's energy storage converter incorporates a water-cooled plate within the housing.

This installation method offers excellent heat dissipation, a compact structure, and saves space. Gold-film capacitors are stacked on top of the power boards, significantly reducing internal space compared to the flat arrangement of existing technologies. Furthermore, since the gold-film capacitors are electrically connected to the power boards, placing them together is scientifically sound and facilitates their electrical connection. A first horizontal partition is positioned above the gold-film capacitors, upon which an electrolytic capacitor is mounted. A second horizontal partition is positioned above the detection board, upon which a relay board is mounted. This effectively utilizes the space above the gold-film capacitors and detection board, further saving internal space and resulting in a very compact structure. This reduces the overall size of the energy storage converter, increases power density, and facilitates connections between components, making the layout highly efficient. The power distribution components are located on the front left side of the base plate, which facilitates the connection between the power distribution components and external cables. Similarly, the placement of the water-cooled plate, power distribution components, power board, gold film capacitor board, inverter inductor, relay board, electrolytic capacitor board and detection board all facilitate the connection between components and are rationally laid out.

[0019] As can be seen from the above, the energy storage converter of this utility model has the advantages of compact structure, small size, high power density, good heat dissipation effect and convenient wiring. Attached Figure Description

It can be a circuit breaker, disconnector, contactor, relay, fuse, etc., and can ensure the safe, reliable, and efficient transmission of electrical energy. Specifically, each component can be fixed by a structure of screws and threaded holes.

[0028] The water-cooled plate 12 can dissipate heat through water or other coolants. The coolant enters from the inlet 13, flows through the water-cooled plate 12 to absorb the heat from the power board 16 and the inverter inductor 18, and finally flows out from the outlet 14.

[0029] In this energy storage converter, an external DC power supply is connected to a power distribution device 15. The power distribution device 15 is electrically connected to a gold film capacitor board 17 via cables or busbars. The gold film capacitor board 17 is electrically connected to a power board 16. The power board 16 is electrically connected to an inverter inductor 18 via busbars. The inverter inductor 18 is connected to a relay board 19 via busbars. The electrolytic capacitor board 20 mainly stores energy and provides a large capacity of charge, while also having multiple functions such as filtering, decoupling, energy storage, and coupling. The detection board 21 is mainly used to detect parameters such as current, voltage, and communication status of other components.

[0030] External DC power enters the gold film capacitor board 17 through the power distribution device 15, and the gold film capacitor board 17 provides the instantaneous large current required for DC commutation; then it flows from the gold film capacitor board 17 into the power board 16, and the power board 16 performs AC-DC power conversion; finally, it flows from the power board 16 into the inverter inductor 18 and the relay board 19, and the inverter inductor 18 and the relay board 19 realize LCL filtering output.

[0031] The energy storage converter of this utility model has a water-cooled plate 12 installed inside the housing 10. The power board 16, which generates significant heat, and the inverter inductor 18 are attached adjacent to each other on the water-cooled plate 12. This installation method provides good heat dissipation, a compact structure, and saves space. The gold film capacitor board 17 is attached to the power board 16 in a stacked arrangement, which significantly saves space within the housing 10 compared to the flat arrangement in existing technologies.

The power distribution device 15 is located at the front left of the base plate 11, facilitating connection between it and external cables. Similarly, the placement of the water-cooled plate 12, power distribution device 15, power plate 16, gold film capacitor plate 17, inverter inductor 18, relay plate 19, electrolytic capacitor plate 20, and detection plate 21 all contribute to the connection between components and a rational layout.

[0033] Better, such as Figure 1 and Figure 2 As shown, the energy storage converter is also equipped with a communication board 26, and a third horizontal partition 27 is provided above the power distribution device 15. The energy storage converter is also equipped with a third support device 28 that supports the third horizontal partition 27, and the communication board 26 is provided on the third horizontal partition 27.

[0034] The energy storage converter of this invention has a communication board 26 installed inside the housing 10. The main function of the communication board 26 is to transmit signals between devices and realize effective information exchange. Compared with the prior art that places the communication board 26 outside the housing 10, the energy storage converter of this invention places the communication board 26 above the power distribution device 15, making good use of the space above the power distribution device 15. The structure is very compact and reasonable, and information exchange function is added on the basis of the original size.

External DC power first passes through the DC filter board 34 before being connected to the power distribution device 15, which can better protect the components inside the enclosure 10. Installing the DC filter board 34 in front of the power distribution device 15 facilitates wiring and has a reasonable structure.
