Abstract:

To provide a low-cost and high-reliability heat exchanger having a very easy-to-produce structure while holding very excellent heat exchange performance.

This heat exchanger has: first base plates 10 nearly parallel formed with long slits 40 and short slits 30; and second base plates 20 formed with slits 50 each having the same shape as the short slit 30, and each having a full length shorter than the long slit 40. The plurality of first base plates 10 and the plurality of second base plates 20 are laminated such that the short slits 30 of the first base plates and the slits 50 of the second base plates communicate with each other, an extra-pipe flow passage 60 is configured by the short slits 30 of the first base plates and the slits 50 of the second base plates, and an in-pipe flow passage 70 is configured by the long slits 40 of the first base plates and the second base plates 20. Thereby, a heat exchange part configured by only a pipe can be configured from the base plates formed with the slits, and production can be easily performed to provide the heat exchanger at low cost.
