ABSTRACT:
A refrigerant evaporator has, at each of a downstream side and an upstream side with respect to a flow direction of air, a pair of upper and lower tanks and a tube connecting the tanks. A refrigerant flows from the pair of tanks and the tube at the downstream side to the pair of tanks and the tube at the upstream side to cool the air flowing outside the tubes. The tanks at the upstream side are formed in an elliptic shape in cross section and the tanks at the downstream side are formed in a circular shape in cross section. The shorter diameter of the elliptic shape lies in a longitudinal direction of the tubes and is the same as the diameter of the circular shape.
