Description

Technical Field

[0001] The present invention relates to the technical field of energy storage converter structures, and in particular to a novel energy storage converter structure. Background Art

[0002] Traditionally, the water-cooled and air-cooled heat dissipation structures of energy storage inverters with the same power have two different shells, with relatively large differences in structural size and appearance, and the internal structure layout is quite different. The cable connections are messy and complicated, which increases the system failure rate and maintenance difficulty. The structural parts have poor versatility, high manufacturing costs, and usually do not have flexible configuration and expansion capabilities. For example, if you need to produce water-cooled energy storage inverters, you need to allocate water-cooled related sheet metal shells, electrical parts, cable kits, water-cooled radiators, waterway-related connectors, etc.; if you need to produce air-cooled energy storage inverters, you also need to allocate sheet metal shells, electrical parts, cable kits, air-cooled radiators, etc. that match the air-cooled inverters. The different structural parts of the two increase manufacturing costs, inventory costs, and production costs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a new energy storage inverter structure with a simple structure and a modular internal structure. The inverter is divided into multiple functional modules, such as a heat dissipation drive component, a control module, a filter module, etc., to improve assembly efficiency, and improve system reliability and maintainability; a cable-less design reduces cable failure rate and maintenance costs, makes the internal structure of the product neat and orderly, enhances product image, and improves system reliability.

[0004] In order to solve the above technical problems, the present invention provides a new energy storage inverter structure, including a shell, in which a converter body is arranged, a control module is arranged at the front end of the upper layer of the converter body, a heat dissipation drive component is arranged at the rear end, and a DC module is arranged on the side of the control module; a filter module is arranged at the front end of the lower layer of the converter body, and a conductive part is arranged between the filter module and the heat dissipation drive component.

[0005] Furthermore, the converter body is an air-cooled energy storage converter or a water-cooled energy storage converter.

[0006] Furthermore, the heat dissipation drive component is an air-cooled drive component, which is connected to the air-cooled energy storage inverter and includes a first fixed plate, on which a first PCB drive board is arranged, an air-cooled radiator is arranged at the bottom of the first fixed plate, and a first IGBT module is arranged on the air-cooled radiator.

[0008] It comprises a water pipe kit, and the water pipe kit is arranged on both sides of the water cooling radiator.

[0009] Furthermore, an AC side conductive member is provided at a position of the filter module away from the heat dissipation drive component.

[0010] Furthermore, a front panel is provided on one side of the shell.

[0011] Furthermore, a fan module is provided at the rear end of the variable fluid body.

[0013] Furthermore, the DC module includes a DC terminal, a fuse, a contactor and a conductive bar.

[0014] Furthermore, the control module includes a PCB control board, a PCB power sampling board, a power box and a mounting plate.

[0015] The beneficial effects of the present invention are as follows: the structural design of the energy storage inverter with the same power is compatible with both air cooling and water cooling. Different heat dissipation methods can be replaced with different radiators, which can be flexibly installed and replaced. The appropriate heat dissipation method can be selected according to customer needs, thereby improving heat dissipation efficiency, improving the flexibility and expansion capability of product configuration, and meeting the needs of different application scenarios; the product shell structure of the air cooling and water cooling heat dissipation methods is shared, which improves the versatility of product parts, reduces product costs, shortens the processing cycle, and improves processing and manufacturing efficiency; the internal structure is modularly designed, and the interior of the inverter is divided into multiple functional modules, such as heat dissipation drive components, control modules, filter modules, etc., to improve assembly efficiency and improve system reliability and maintainability; the cable-less design reduces cable failure rate and maintenance costs, makes the internal structure of the product neat and orderly, enhances product image, and improves system reliability.
