Abstract
A cover assembly and a power conversion device comprising the same are disclosed. The cover assembly according to an embodiment of the present disclosure is detachably coupled to an inverter device. The cover assembly communicates with the inside of the inverter device, and is coupled to the inverter device while covering a blower fan. Therefore, the blower fan is not exposed to the outside, and thus the blower fan can be prevented from being arbitrarily damaged, and introduction of dust and the like residing outside the inverter device into the inverter device can be prevented.
