Abstract: A refrigerant evaporator has an interchange part. The interchange part connects a first collecting part of a second downstream tank part, and a second distribution part of a second upstream tank part. The interchange part connects a second collecting part of a second downstream tank part, and a first distribution part of a second upstream tank part. The interchange part swaps a refrigerant about a width direction of a core. Refrigerant passages relevant to the interchange part are configured to improve refrigerant distribution. Providing a plurality of passages and/or twisting a passage improve distribution.

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.

Abstract translation: 制冷剂蒸发器包括四个芯部分。 制冷剂的一部分通过第一芯部和第四芯部。 制冷剂的另一部分通过第二芯部分和第三芯部分。 交换单元交换制冷剂流动的位置。 第二芯部与第三芯部连通的通道包括在中间罐单元中的节流通道。 中间罐单元的节流通道和端部将制冷剂流朝向分隔件反向。 由于通过节流通道调节液相制冷剂的分配，因此抑制了液相制冷剂在第三芯部的出口附近的位置的浓度。 因此，抑制位于制冷剂流下游的芯部的液相制冷剂的浓度。
