Abstract
A refrigerant evaporator includes four core portions. A part of the refrigerant passes through a first core portion and a fourth core portion. The other part of the refrigerant passes through a second core portion and a third core portion. An exchanging unit exchanges the positions where the refrigerant flows. A passage through which the second core portion communicates with the third core portion includes a throttle passage in the intermediate tank unit. The throttle passage and the end portion of the intermediate tank unit reverse the refrigerant flow toward a partitioning member. Since the distribution of a liquid-phase refrigerant is adjusted by the throttle passage, a concentration of the liquid-phase refrigerant on a position in the vicinity of an outlet of the third core portion is suppressed. Accordingly, the concentration of the liquid-phase refrigerant in the core portions located downstream of the refrigerant flow is suppressed.
