PROBLEM TO BE SOLVED: To reduce occurrence of dead water of the first fluid near a communication part at a heat exchanger.SOLUTION: A heat exchanger has a flowing path where the first fluid flows and is provided with a plurality of plates arranged to be adjacent to each other. Each of a plurality of plates comprises a main body part having a general flow passage acting as a flow passage where the first fluid flows in the plate and a communicating part having a communicating flow passage acting as a flow passage from the plate to another plate. The communicating part is formed in such a way that a representative length of the communicating part in the communicating passage is longer than a representative length of a connecting part to the communicating flow passage in the general flow passage of the main body.SELECTED DRAWING: Figure 3 |
