PROBLEM TO BE SOLVED: To provide a plate-type heat exchanger capable of changing a temperature of a heat-exchanged medium of which heat is exchanged by a heat exchanging medium, to different temperature, and more efficiently exchanging heat by suppressing pressure loss generated on the heat-exchanged medium.SOLUTION: A plate type heat exchanger includes first heat transfer plates 101 and second heat transfer plates 102 alternately forming first circulation spaces 10 and second circulation spaces 30. Partitioning portions 103 are formed on at least the first heat transfer plates 101 or the second heat transfer plates 102. The partitioning portions 103 partition the first circulation spaces 10 into first areas 11 for circulating a first refrigerant 1, and second areas 12 for circulating a second refrigerant 2. |
