A pedestal plate 18 forming both side surfaces of the heat exchanger 10 is disposed on both end surfaces of the core portion 12 in the stacking direction. The widths of the tubes 14, the fins 16 and the pedestal plate 18 (shown by a in FIGS. 7 and 8) are the same. Tanks 20 are provided at both ends of the tube 14 in the longitudinal direction. This tank part 20
Is a seat plate 24 having a U-shaped cross section and having an insertion hole 22 for inserting the tube 14 slightly larger than the width of the tube 14, and a tank capsule 26 covered from the outside of the seat plate 24. It is formed by and. As a result, the width of the core portion 12 (shown as a in FIGS. 7 and 8) is naturally smaller than the width of the tank portion 20 (shown as b in FIG. 8).

In such a heater core 10, by increasing the width of the tube 14 in the air flow direction as shown in FIG. 3, it is possible to maximize the cross-sectional area of the hot water passage in the tube 14 and reduce the water flow resistance. It will be possible. Further, the hot water heat transfer area and the air heat transfer area in the tube 14 are increased, and the heat exchange capacity can be significantly improved. Moreover, the thinner the wall thickness of the tube 14, the larger the cross-sectional area of the hot water passage can be.

実現できる。FIG. 4 shows the heater core 10 attached to the case 47. The heater core 10 has a substantially rectangular upper surface because the core portion 12 and the tank portion 20 have the same width. Then, a heater core insertion opening 32 (heat exchanger insertion opening) for taking in the heater core 10 is formed in a case 47 having an air passage and accommodating the heater core 10 so as to have the same shape as the upper surface of the heater core 10. When the heater core 10 is inserted from above in FIG. 4, the outer peripheral surface of the heater core 10 and the heater core insertion opening 32
And come into close contact. As a result, the packing for preventing wind leakage as in the past can be eliminated and the cost can be reduced.

The tank capsule 26 may be arranged inward. Further, as shown in FIG. 6, a plate member made of an aluminum alloy is bent so that the cross-sectional shape becomes a substantially square shape, and the tank portion 20 is formed.
To form. In addition, the maximum width of the tank portion 20 is set to the tube 1
Equivalent to 4. Then, the outer peripheral wall 70 may be cut out over the maximum width to form a contact surface that contacts the end surface 60 of the tube 14.
