Claims

[Scope of utility model registration request]

This is a ceramic heat exchanger manufactured by laminating thin unfired ceramic plates and firing them together, and includes high-temperature fluid passages 3 and low-temperature fluid passages 4 formed at every other stage through ceramic partition plates 1. In each case, a plurality of rows 8a of a large number of long holes 8 arranged at equal pitches in the fluid flow direction form a plurality of rows in the horizontal direction on the plate surface 7', and the positions of the long holes 8 in these plural rows are arranged at different positions. They are shifted back and forth in each row, with the long holes at the front cutting out the fluid inlet end of the plate surface in 9 rows, and the long holes at the rear cutting out the fluid outlet end of the plate surface in 10 rows. By overlapping two ceramic plates 7 of the same shape, which are formed so that they are alternately formed, with the front and back positions of the ceramic plates reversed, the elongated holes 8 of the two stacked ceramic plates 7 are partially aligned with each other. A heat exchanger made of ceramics, characterized in that it is formed into wave-shaped fluid passages that overlap each other and allow fluid to flow in a wave-like manner.
