ABSTRACT:
A heat exchanger having outer surfaces thereof coated with a hydrophilic coating layer. The hydrophilic coating layer essentially consists of a resin as a base, containing a colloidal silica. In the hydrophilic coating layer, part of silanol groups of the colloidal silica are chemically combined with part of hydroxyl groups of the resin. Due to this chemical combination, the colloidal silica undergoes change in its properties such that it has degraded adsorptivity, making smells less liable to attach to the colloidal silica.
