摘要
A plurality of heat transfer plates having openings at the four corners are laminated, a part of each of the heat transfer plates is brazed and joined, and the first flow path through which the first fluid flows and the second flow path through which the second fluid flows are each It is formed alternately with the heat transfer plate as a boundary, and each of the openings at the four corners is connected to form a first header for flowing in and out of the first fluid and a second header for flowing in and out of the second fluid. In the plate-type heat exchanger, at least one of the heat transfer plates sandwiching the first flow path or the second flow path is configured by overlapping two metal plates, and two metal plates Of the plates, the metal plate located on the second flow path side is thinner than the metal plate located on the first flow path side.
