[0002] A converter is an electronic circuit device used to change the type of voltage and current. During operation, converters generate heat. If heat is not dissipated in time, the converter may burn out. Currently, converters are cooled by top-mounted exhaust fans. However, during this process, dust is also drawn in, which can damage the converter, reduce its lifespan, and affect production efficiency. Therefore, dust filters are usually installed inside the cooling duct to protect the converter. However, in dusty environments, frequent maintenance of these dust filters is required. Existing converter dust filter structures are cumbersome to install and remove, making filter replacement inefficient and time-consuming. Therefore, we need to propose a converter with a quick-change dust filter function. Utility Model Content
