Claims

[Scope of utility model registration request]

The headers arranged vertically opposite each other are communicated through a large number of heat exchange tubes, and the interior of one header is partitioned left and right to form an inflow chamber and an outflow chamber, and the inflow chamber and the outflow chamber of the tank of the header are divided into left and right sections. An inflow pipe and an outflow pipe are inserted and fixed into openings formed in the outflow chamber, so that hot water circulates, and at least one of the inflow pipe and the outflow pipe inserted into the inflow chamber and the outflow chamber is fixed. A heat exchanger for an automobile that has a plurality of notches provided along the circumferential direction at the tip.
