1. A ceramic heat exchanger made of a ceramic, for forcing a first medium and a second medium, different in temperature, to flow in opposite directions to transfer heat between the first and second media, comprising:
a body having first channels for the first medium to flow and second channels for the second medium to flow disposed axially in the body with second channels defined in top, middle and bottom portions of the body, and lids each having openings, joined to axially opposite ends of the body with the openings connected to the first channels, wherein: the body further having inlet channels formed in a first channel outlet-side end portion to allow the second medium to enter the body at a side thereof and flow into the second channels, and outlet channels formed in a first channel inlet-side end portion to allow the second medium to flow out of the second channels and leave the body at the side thereof, the inlet channels as well as the outlet channels being grooves formed in the body and delimited by an inner side of the lid, the grooves extending transversely across the body and connecting to respective second channels in the top, bottom and middle portions of the body, and the grooves connecting the second channels in the middle portion of the body have greater dimensions in the axial direction of the body than the grooves connecting the second channels in the top and bottom portions of the body. |
