A series-hybrid vehicle includes an internal combustion engine for electric power generation and a motor generator for travelling. The internal combustion engine is cooled by a second coolant water circuit that has a main radiator. A first coolant water circuit having a sub radiator is used to cool a front wheel-side power train cooling part, a rear wheel-side power train cooling part, a water-cooled condenser, and a low temperature-side intercooler. When the vehicle is accelerating, an electrical compressor for an air conditioner comes to a stop, and the circulation of refrigerant to the water-cooled condenser is brought to a halt.

A tube type heat exchanger includes a core includes multiple tubes, a header plate defining an array of apertures in which said tubes are received, and a coolant jacket arranged about said core. The header plate includes a body defining a central region and an edge region circumferential to said central region. The central region defines said array of apertures. The edge region includes a flange. The header plate is connected to the coolant jacket via first and second contact areas between the header plate and the coolant jacket. The flange is outboard of the coolant jacket. The first contact area is between the flange and the coolant jacket; and the second contact area is inboard of the first contact area.

A heat exchanger includes: flat tubes; a plate attached to the flat tubes; a medium tank configured to form a medium flow path by covering openings of flat tubes; and a reinforcing member to reinforce the openings. The reinforcing member includes a pair of leg portions and a connection portion that connects the leg portions. An insertion amount of the leg portions into the opening is larger than a sum of a gap between the connection portion and an inner surface and a length from the opening to a position corresponding to a brazed portion between the flat tube and the plate, or when a protruding portion protruding in a direction opposite an insertion direction is provided in the connection portion, larger than a sum of a gap between the protruding portion and the inner surface and a length from the opening to the position corresponding to the brazed portion.

An apparatus for removing condensed water of an intercooler includes a collecting portion for collecting condensed water, the collecting portion being provided at a lower end of the intercooler; and an ultrasonic wave vibrator provided in the collecting portion, the ultrasonic wave vibrator being operated to introduce the condensed water collected in the collecting portion toward an engine so that the condensed water is vaporized, thereby removing or significantly reducing an amount of condensed water in the intercooler. The apparatus for removing condensed water of the intercooler can prevent engine damage and ignition failure due to the presence of the condensed water in the intercooler.
