Abstract

PURPOSE:To obtain a smooth flow passage which prevents an abrupt change in the moving direction of a fluid by laying out a plurality of heat transfer plates provided with distribution ports which let a fluid A and a fluid B having a differential temperature to flow respective in such a manner that the relative positions of said distribution ports may be phase-deviated. CONSTITUTION:A passage 10A of a fluid A runs along the surface of adjacent heat transfer plates 4, passing by a distribution port 11A. The passage 10A is spiral-shaped on the laminated layer of the heat transfer plates 4. In a similar manner, a flow passage of a fluid B runs on the surface of the heat transfer plates 4 and a distribution port 11B and turns into a spiral-shaped flow passage 10B. At that time, heat-exchange take places because it faces a fluid having a differential temperature with the heat transfer plates 4 placed between. This construction makes it possible to allow the fluid to flow smoothly with a minimum change, preventing its abrupt change in its flow direction.
