METHOD FOR MANUFACTURING HEAT EXCHANGER

WIPO Patent Application WO/2020/031780

A1

This method for manufacturing a heat exchanger includes a molding step in which a raw material composition containing silicon carbide particles is used to form a molded body which is provided with first flow passages R1 and a plurality of second flow passages R2. This molding step includes: a first molding step for forming a sheet-like first molded body which forms the first flow passages R1 in the molded body, and which has on the surface thereof a plurality of protrusions 25 scattered in the flow direction of a first fluid and in a direction crossing said flow direction; a second molding step for forming a sheet-like second molded body which forms the second flow passages R2 in the molded body; and a stacking step for stacking the first molded body and the second molded body together.
