A heat radiation fin(21) is installed in a horizontal direction. An inlet and an outlet are formed in both ends of the heat radiation fin. A cooling fan(24) is installed in the outlet side of the heat radiation fin and induces a cooling wind from an inlet to an outlet. A heat sink(20) is installed in the bottom of the heat radiation fin. A power module for the DC/DC converter is attached to the bottom of the heat sink. A case(23) is installed in the bottom of the heat radiation fin to block the power module from the external air. A cooling channel(25a,25b) is slantingly formed in both sides of the heat sink to connect the cooling wind of the heat radiation fin into the inner side of a case. An overall surface of the power module is exposed to the cooling wind inputted to the inner side of the case.

Abstract: PURPOSE: A method for controlling an output voltage of a DC-DC converter for a hybrid vehicle is provided to increase an output voltage of the DC-DC converter when the temperature of external air is low, thereby increasing charging performance of a sub battery. CONSTITUTION: If the starting of a vehicle is turned on, it is determined whether the temperature(Tx) of external air is lower than a boundary temperature(Tx1). If the temperature of external air is higher than the boundary temperature, a DC-DC converter normally operates. If the temperature of external air is lower than the boundary temperature, a voltage of an output terminal or a sub battery of the DC-DC converter is measured to select a driving mode of the vehicle. If a voltage of the output terminal of the DC-DC converter or a voltage of a 12V sub battery is lower than a fixed voltage, the vehicle operates in a strong charging mode. If a voltage of the output terminal of the DC-DC converter or a voltage of the 12V sub battery is higher than a fixed voltage, the vehicle operates in a weak charging mode.
