摘要： A long continuous tube, strip or like material has a coating of brazing powders applied and formed thereon. It may be cut to sections of specific length when actually used. A uniform coating of brazing powders is applied in specific quantities and fixed onto the long continuous tube, strip or like material. A travel path has a tube made from aluminum or aluminum alloy running therealong. At least one spray gun section projects a coating mixture of brazing powders toward the travel path. A pressurized air supply section supplies pressurized air to the spray gun section, and a coating mixture supply section includes a coating mixture circulating arrangement and a feed line. A drying section is provided downstream of each respective spray gun section, and a rewinding section is provided at the end of the travel path. The tube runs at a constant speed along the travel path and passes through the first spray gun section, where a coating mixture of brazing powders is applied against one side of the tube, and the other goes through the first drying section, where the coating is dried and fixed. Then, the tube is reversed, running in the opposite direction and passing through the second spray gun section, where a coating mixture of brazing powders is applied against the opposite side of the tube. It then goes through the second drying section, where the coating is dried and fixed. The finished tube is finally would up in a coil at a rewinding section.

摘要： A heat exchanger, characterized in that Al or Al alloy tubes, each having a thermally Zn-sprayed layer formed on the surface of it, and having a brazing filler metal layer formed on said thermally Zn-sprayed layer using a powdery brazing filler Al alloy composed of 5 to 60 weight % of Si and the balance of Al and unavoidable impurities, are combined with and brazed to an Al or Al alloy header having a brazing filler metal layer formed using a powdery brazing filler Al alloy composed of 5 to 60 weight % of Si and the balance of Al and unavoidable impurities. The tubes and the header are strongly bonded to each other, and Zn is uniformly diffused and distributed. So, the heat exchanger shows good corrosion resistance.
