EVAPORATOR

摘要

Disclosed is an evaporator (100) wherein heat is exchanged between cooling water and a cooling medium. The evaporator (100) is provided with: a cooling medium channel (17f), which has a cooling medium inflow port (17c) and a cooling medium outflow port (17d), and has the cooling medium circulated therein; and a heating medium channel (18f), which is provided such that the heating medium channel can exchange heat with the cooling medium channel (17f), and which has a heating medium inflow port (18c), and a heating medium outflow port (18d), and has the cooling water circulated therein. The heating medium inflow port (18c) is disposed at a position that corresponds to a region of the cooling medium that has been brought into the vapor state from the liquid state by means of the heat exchange with the cooling water in the cooling medium channel (17f). The heating medium channel (18f) has a partition wall (18w) that guides the cooling water such that the cooling water flowed in from the heating medium inflow port (18c) flows along the region of the cooling medium that has been brought into the vapor state.
