Abstract:
A heat exchanger includes tubes and a header tank. The header tank includes a core plate and a tank body. The core plate includes a tube connection surface and a receiving portion that houses an end portion of the tank body. The receiving portion includes a bottom wall and an inner wall that connects the bottom wall to the tube connection surface. The tube connection surface and the inner wall are connected to a rib. The rib is located between adjacent two tubes and inclined with respect to a longitudinal direction of the tubes. The rib includes one end connected to the tube connection surface and an other end connected to the inner wall. The tubes includes lateral ends in the width direction, and a clearance, which has a specified dimension, is defined between the inner wall and the lateral ends in the width direction.

Claim (Index 1):
A heat exchanger comprising:\n a plurality of tubes that are stacked and have a flat shape; and a header tank that is positioned on a side of the plurality of tubes in a longitudinal direction of the plurality of tubes, the header tank being in communication with the plurality of tubes, wherein the header tank includes\n a core plate that is coupled with longitudinal ends of the plurality of tubes and \n a tank body that is fixed to the core plate, the core plate includes \n a tube connection surface that includes a plurality of tube insertion holes corresponding to the plurality of tubes, the plurality of tubes being inserted into the plurality of tube insertion holes and brazed to the tube connection surface and \n a receiving portion that surrounds the tube connection surface and houses an end portion of the tank body which is located adjacent to the core plate, \n the receiving portion includes\n a bottom wall that faces the tank body across a sealing member and \n an inner wall that connects the bottom wall to the tube connection surface, \n the tube connection surface and the inner wall are connected to a rib, which is located between adjacent two tubes of the plurality of tubes and inclined with respect to the longitudinal direction, the rib includes one end and an other end facing each other in a width direction of the plurality of tubes, the one end being connected to the tube connection surface, the other end being connected to the inner wall, and the plurality of tubes include lateral ends in the width direction, and a clearance, which has a specified dimension, is defined between the inner wall and the lateral ends in the width direction.
