<p>The invention relates to an electrical device. Supporting walls (46, 48) are connected with a separating plate (40) and a bottom wall (30) in a housing (26) at an interval. One end of cooling part (56) is arranged on the supporting wall (46), and the other end is connected with the supporting wall (48). The outer surface of the cooling part (56), the inner surface of the separating plate (40), the inner surfaces of the supporting walls (46, 48), and the inner surfaces of the side walls (32, 34) form a chamber (54). The outer surface of the cooling part (56) is provided with a semiconductor element (88). A control part installation plate (96) is arranged above the separating plate (40) and forms a chamber (44) of an electrical element (94) with the side walls (32, 34), end walls (36, 38), and a top wall (28), and forms a cooling path (97) with the separating plate (40). A fan (76) guides the air into the housing (26), and the air is discharged to the outside of the housing (26) via an air outlet (84) after passing a cooling path (68) of the cooling part (56). The air is guided into the cooling path (97) via a connecting hole (90), and then flows to the air outlets (84, 86) via a connecting hole (72).</p> |
