ABSTRACT:
In a heat exchanger, a liquid resin is applied to an outer surface of the heat exchanger, and then surplus liquid resin is removed from the outer surface. In removing the surplus liquid resin, before air having a first velocity is directed to the heat exchanger for blowing the surplus liquid resin off the heat exchanger, air having a second velocity lower than the first velocity is directed to the heat exchanger to remove the surplus liquid resin from the heat exchanger by moving the surplus liquid resin along the outer surface of the heat exchanger. The air at the second velocity is directed toward the heat exchanger by a second blower before the air at the first velocity is directed toward the heat exchanger by a first blower.
