摘要
An coating apparatus, wherein the apparatus applies a coating, onto a surface of an aluminum alloy member for a heat exchanger to be assembled by brazing, with a top-feed-type roll transfer system having at least three rolls, the coating being obtained by mixing into an organic binder a metal powder, a flux powder, a powder mixture thereof, or a compound containing a metal component and a flux component, wherein rotation directions of transfer rolls of the apparatus arranged above a surface to be coated of an aluminum alloy extruded member that moves in a horizontal direction, satisfy a relationship in which a rotation direction of a coated-metal roll for coating, which rotates in a direction opposite to a moving direction of the extruded member, and a rotation direction of a metal roll for adjusting an adhesion amount of the coating by contacting with the above roll, are opposite to each other; and a method of producing an aluminum alloy heat exchanger member using the apparatus; and an aluminum alloy heat exchanger member.
