[0002] The housing of a rack-mounted inverter is usually made of metal materials, such as aluminum alloy. Aluminum alloy has good thermal conductivity, corrosion resistance and mechanical strength, making it very suitable for making the housing of an inverter. The aluminum alloy housing can not only effectively protect the internal circuits and components from the influence of the external environment, but also quickly dissipate the internal heat through its good thermal conductivity, ensuring the stable operation of the inverter.

[0003] Both ends of the existing rack-mounted inverter power supply housing are usually provided with hanging ears. Since the connection method between the hanging ears and the housing is relatively fixed, it is inconvenient to adjust the direction of the hanging ears. The housing on which the inverter power supply needs to be installed can only be installed along the fixed direction of the hanging ears, which is inconvenient to adjust the overall direction of the inverter power supply housing. The installation method has certain limitations, and the cover plate of the existing inverter power supply housing and the housing are generally fixed by multiple bolts. When the components inside the housing need to be maintained, it is troublesome to disassemble and inconvenient to use. Therefore, it is necessary to propose a rack-mounted inverter power supply housing to solve the above-mentioned problems. Utility Model Content
