[0031] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0032] Please refer to Figure 1 as well as Figure 2 A horizontal air-cooled energy storage converter comprises a horizontal cabinet, wherein the front and rear sides of the horizontal cabinet are respectively provided with a detachable front door sealing plate and a detachable rear door sealing plate;

[0033] The front space of the horizontal cabinet is provided with a control compartment, a fire module box, an AC input module, a power control unit and a DC output module. The fire module box is located in the control compartment. The front space is the side of the interior of the horizontal cabinet close to the front door cover.

[0034] An air conditioner, an auxiliary power transformer, a filter module, and a power module are arranged in the rear space of the horizontal cabinet. The power module includes an air cooling device. The rear space is a side of the interior of the horizontal cabinet close to the rear door cover.

[0035] The front door cover is provided with several front air inlet louvers corresponding to the AC input module and the DC output module; the rear door cover is provided with a cooling fan corresponding to the auxiliary power supply transformer and the filter module, and air outlet louvers and rear air inlet louvers are provided at the power module and the air cooling device respectively.

[0036] As can be seen from the above description, the beneficial effects of the present invention are as follows: components that require operation during use are placed at the front of the cabinet, making daily operation more convenient; components that do not require operation and require less frequent maintenance are placed at the rear, which can be removed from the rear door cover for maintenance; the removable cover panels on the front and rear doors facilitate component installation during the manufacturing process; components inside the cabinet are arranged horizontally, reducing the height space occupied. The cabinet height is minimized while meeting the installation height requirement, allowing the cabinet to meet specific installation requirements in height-restricted environments.

[0037] Furthermore, an opening is provided at one end of the horizontal cabinet, and a high-voltage connector is provided at the opening.

[0038] As can be seen from the above description, a high-voltage connector is provided at an opening at one end of the horizontal cabinet to realize the function of supplying power to the outside or connecting to other devices.

[0039] Furthermore, the DC output module is arranged in front of the high-voltage connector; the DC output module is electrically connected to the high-voltage connector;

[0040] The power module and the air cooling device are provided in the rear space at a position corresponding to the DC output module.

[0041] As can be seen from the preceding description, the DC power output by the DC output module is transmitted to external cables through a high-voltage connector. The power module converts and regulates electrical energy, converting AC input into DC output. At the same time, the power module's built-in fan draws in external air through the air inlet louvers on the rear door cover, which enters the module for cooling, ensuring normal operation.

[0042] Furthermore, the power control unit is arranged at a position close to the DC output module, and a filter module is provided in the rear space corresponding to the position of the power control unit.

[0043] From the above description, it can be seen that the power control unit is set close to the DC output module, which is conducive to more efficient power control and conversion, reducing energy loss and interference; the AC component in the pulsating DC can be filtered out by the filtering module, reducing the AC component and increasing the DC component.

[0044] Furthermore, the AC input module is arranged at a position close to the power control unit, and an auxiliary power supply transformer is provided in the rear space at a position corresponding to the AC input module.

[0045] From the above description, it can be seen that the auxiliary power supply transformer, which requires no operation and has a low maintenance frequency, is placed in the rear space to provide 220V auxiliary power supply for the electrical appliances inside the cabinet.

[0046] Furthermore, the control compartment is arranged at a position close to the AC input module, and an air conditioner is provided in the rear space corresponding to the position of the control compartment.

[0047] As can be seen from the above description, the control compartment is equipped with an air conditioner to cool down the components in the control compartment and ensure their operating temperature.

[0048] Furthermore, the rear door sealing plate is provided with a bracket for supporting the air conditioner, and the air conditioner is arranged on the bracket.

[0049] From the above description, it can be seen that installing the air conditioner on the bracket of the rear door cover facilitates heat exchange between the air conditioner and the external environment, thereby ensuring the cooling effect of the air conditioner.

[0050] Furthermore, filter cotton is provided inside the front air inlet louvers, the rear air inlet louvers and the air outlet louvers.

[0051] From the above description, it can be seen that the filter cotton arranged inside the louver filters the dust and other impurities in the air entering and leaving the cabinet to ensure the cleanliness of the cabinet.

[0052] Furthermore, a partition is provided between the power module and the air cooling device.

[0053] As can be seen from the above description, the partition between the power module and the air cooling system allows for a circulation of air in and out of the power module. Specifically, the power module's built-in fan draws in external air through the air inlet louvers on the rear door cover, which then enters the module for cooling. The air is then discharged from the top left side of the module into the cabinet. The warmer air inside the cabinet is then discharged outside the cabinet through the air outlet louvers. The partition ensures an effective circulation path between the inlet and outlet air, improving cooling efficiency and ensuring the normal operation of the power module.

[0054] Furthermore, a plurality of mounting back panels parallel to the front door sealing plate are provided inside the horizontal cabinet.

[0055] From the above description, it can be seen that installing a back panel facilitates the orderly arrangement and installation of components and can also separate different functional areas; it helps to form an air duct, cooperate with louvers and cooling fans to promote air circulation and improve the cooling effect; it plays a certain supporting and fixing role for the components and enhances the structural stability of the cabinet.
