Patent ID: 8787018

Claim:
A power converting apparatus configured to convert alternating current power into direct current power or convert direct current power into alternating current power, the power converting apparatus comprising: a housing comprising: a housing base having a first surface and a second surface; a main body comprising a plurality of electronic components on the first surface of the housing base; and an air duct through which cooling air flows on the second surface of the housing base; a cylindrical capacitor penetrating through the housing base so that a part of the capacitor is disposed in the main body while a rest part of the capacitor is disposed in the air duct; and a cylindrical capacitor cover on the housing base, the capacitor cover covering the rest part of the capacitor, the capacitor cover comprising: an elastic material; a cylindrical capacitor cover body being closed at one end and open at another end; an inner surface defining an inner diameter approximately equal to an outer diameter of the capacitor such that the inner surface of the capacitor cover is in close contact with an outer surface of the capacitor when the capacitor cover is provided over the rest part of the capacitor; at least one groove, on the inner surface, extending in an axial direction of the capacitor cover; and an annular flange directly connected to and extending in a radially outward direction from the another end that is open, wherein the one end of the capacitor cover that is closed being provided within the air duct, and the annular flange directly abuts and is secured to the first surface of the housing base.
