According to the present invention, plural downstream side evaporation passages (21) in a downstream side heat exchanging unit (2) are divided into two groups substantially at the middle of the width by a separator (27), plural upstream side evaporation passages (31) in an upstream side heat exchanging unit (3) are divided into two groups substantially at the middle of the width by a separator (36), and a downstream side lower tank (23) and an upstream side upper tank (32) are communicated by a communication passage (44) so that inefficient heat exchanging areas of the downstream side heat exchanging unit (2) and the upstream side heat exchanging unit (3) disposed one after the other with respect to the flowing direction of air may not overlap with each other. Since the inefficient heat exchanging area in the downstream side heat exchanging unit (2) and the inefficient area in the upstream side heat exchanging unit (3) are disposed symmetrically with each other, the temperature distribution of air blown out from the refrigerant evaporator (1) is prevented from being biased, and air having a uniform temperature distribution can be produced by the refrigerant evaporator (1). <IMAGE> |
