<P>PROBLEM TO BE SOLVED: To provide a power conversion device which can easily be attached to and detached from a power module. <P>SOLUTION: The power conversion device 1 comprises: the power module 2 having a switching element 4 and a cooler 5 in which a coolant for cooling the switching element 4 flows; a conductive member 6 which supports the power module 2, is connected to an electrode terminal 41 of the switching element 4, and serves as a current passage of a driven current; and a supporting body 3 having a coolant passage 7 which makes a coolant fed to the cooler 5 and a coolant discharged from the cooler 5 flow, respectively. The power module 2 is connected to at least a cooling passage connecting part 11 connected with the cooler 5 and the coolant passage 7, and the supporting body 3 in an electric connection part 12 in which the electrode terminal 41 of the switching element 4 and the conductive member 6 are electrically connected to each other. When attaching and detaching either of the cooling passage connecting part 11 and the electric connection part 12, the other is also attached and detached. <P>COPYRIGHT: (C)2009,JPO&INPIT |
