Abstract:
A core plate of header tanks in a heat exchanger includes a tube joint portion on which a plurality of tube insertion holes is formed, a receiving portion surrounding the tube joint portion and housing a tip part adjacent to the core plate in the tank body portion, and a inclined portion connecting between the receiving portion and the tube joint portion and inclined with respect to a longitudinal direction of the tube. The inclined portion is provided on the core plate such that a first virtual line extending linearly along the inclined portion from the receiving portion toward the tube joint portion and a second virtual line extending linearly along the tube joint portion in a direction of a long diameter in a cross section of the tube are intersected outside of the tube in the width direction of the tube.

Claim (Index 1):
A heat exchanger, comprising:\n a core portion having a plurality of tubes formed as a flat shape and stacked with each other; and header tanks provided on an end part of the tube in a longitudinal direction of the tube and communicating with the plural tubes, wherein the header tanks comprises:\n a core plate brazed and joined to the plural tubes in a state that the end parts of the tubes in the longitudinal direction of the tubes are inserted in a plurality of tube insertion holes, and \n a tank body portion fixed to the core plate and forming a space communicating with the plural tubes together with the core plate, wherein\n the core plate comprises:\n a tube joint portion in which the plural tube insertion holes are formed, \n a receiving portion surrounding the tube joint portion and housing a tip part which is close to the core plate in the tank body portion, and \n an inclined portion connected between the receiving portion and the tube joint portion, and inclined with respect to the longitudinal direction of the tube, wherein \n \u2003a first virtual line is defined as extending linearly along the inclined portion from the receiving portion toward the tube joint portion, \n \u2003a second virtual line is defined as extending linearly along the tube joint portion in a direction of a long diameter in a cross section of the tube, and \n \u2003the inclined portion is provided on the core plate such that an intersection between the first virtual line and the second virtual line is positioned outside of the tube in the width direction of the tube.
