Claims

[Scope of utility model registration request]

A laminate is formed by alternately stacking two types of dish-shaped plates each having a peripheral flange around a bottom plate having a large number of protrusions and fitting each peripheral flange in sequence, and forming a layered cavity within the laminate. are connected to each other through a pair of communicating tubes in every other layer, an upper end plate and a lower end plate are fixed to the upper and lower end surfaces of the laminate, and two openings in each pair communicating with each pair of communicating tubes are connected to the A housingless heat exchanger provided on either an upper end plate or a lower end plate, characterized in that the number of protrusions on one of the plates is smaller than the number of protrusions on the other plate.
