1. A frequency converter for driving a motor, comprising:

  • a circuit board, having at least one first heat-generating element mounted thereon;

    at least one second heat-generating element having a main body protruding from the circuit board;

    a separating member for separating the at least one portion of the main body of the at least one second heat-generating element from the circuit board, so as to prevent cooling air guided to the at least one second heat-generating element from flowing to the circuit board;

    a heat sink, connected to the at least one first heat-generating element;

    a fan, facing the heat sink; and

    a bracket, for positioning the at least one first heat-generating element relative to the heat sink and the circuit board;
