<p>Refrigerant flow changing parts (13c, 13d), which guide the refrigerant in a first refrigerant convergence part (13a) to a second refrigerant distribution part (23b) and guide the refrigerant in a second refrigerant convergence part (13b) to a first refrigerant distribution part (23a), are provided inside a second downstream tank part (13) of a downstream evaporation part (10). The refrigerant flow changing parts (13c, 13d) are constructed such that the flow of the refrigerant guided from the first refrigerant convergence part (13a) to the second refrigerant distribution part (23b) and the flow of the refrigerant guided from the second refrigerant convergence part (13b) to the first refrigerant distribution part (23a) are in a nonintersecting state when viewed from the lengthwise direction of tubes (111, 222). Thus, the refrigerant flow can be switched in the width direction of core parts without increasing the filling amount of the refrigerant, and the cooling performance with respect to a fluid to be cooled can be improved.</p> |
