Each of tanks of a heat exchanger includes a tube joint portion and a tank body portion which define an internal space of the tank. The tube joint portions of the tanks constitute a single core plate. The tank body portions each have a claw protruding toward a core portion. The core plate is provided with a hole that fits with the claw. In a state in which the claw is fitted into the hole, the tank body portions are fixed to the core plate.

Heat exchanger

A heat exchanger includes left and right header tanks disposed in parallel; top and bottom side plates that couple respectively both ends of the pair of the header tanks; a first plurality of tubes connected between the pair of the header tanks at both ends that are disposed in a region nearer the bottom side plate as a condenser; and a second plurality of tubes that are disposed in a region nearer the top side plate as an oil cooler. Each tube in the second tubes has a cross-sectional shape identical to that of each tube in the first tubes and the top side plate is formed to have a squared U-shaped cross section so that a return pipe communicating with the second tubes can be disposed along a groove having the squared U-shaped cross section of the top side plate.

A cooler cools a plurality of electric parts from both sides thereof. The cooler includes a plurality of cooling units including a pair of cooling tubes for flowing coolant therethrough. A pair of cooling tubes having a flat shape is disposed to sandwich the electric part so that both sides of the electric part are cooled by a pair of cooling tubes. The cooling units are disposed to align in a stacking direction. A clearance is disposed between the neighboring cooling units in the stacking direction.
