Patent ID: 8240048

Claim:
A method of manufacturing an adsorption heat exchanger by dipping a heat exchanger main body, the heat exchanger main body being provided with a plurality of plate-like fins arrayed in an extension direction of a heat transfer tube, into a slurry source liquid prepared by dispersion of an adsorbent in a liquid binder, to thereby form an adsorption layer on the surface of the heat exchanger main body, the method comprising: a dipping step in which the heat exchanger main body is dipped into the source liquid; a scattering step in which the heat exchanger main body after having undergone the dipping step is rotated in the air around a rotary shaft extending along the direction in which the plurality of fins are arranged; and a drying step in which the heat exchanger main body after having undergone the scattering step is dried, wherein the plurality of fins are formed in a rectangular plate shape; and wherein in the scattering step the heat exchanger main body is rotated in such a position that one of the long edges of each of the plurality of fins points towards the rotary shaft.
