Abstract:
1. A countercurrent heat exchanger, comprising: a pair of heat exchanger cores having multiple tubes and fins which are arranged alternately, the heat changer cores being arranged next to each other in a depth direction thereof; a U-turn intermediate tank connected with one end sides of the tubes contained in the heat exchanger cores; an inflow-side tank connected with the other end sides of the tubes contained in one of the heat exchanger cores; and an outflow-side tank formed to be separated from the inflow-side tank, the outflow-side tank being connected with the other end sides of the tubes contained in the other of the heat exchanger cores, wherein the inflow-side tank, the outflow-side tank and the intermediate tank are attached to a vehicle body side, wherein the inflow-side tank and the outflow-side tank are attached to the vehicle body side through brackets and bolts which are set to allow a relative movement therebetween so that the both heat exchanger cores can expand and contract independently from each other with respect to the intermediate tank.
