Abstract

See full text

Microextruded tubes each having two side surfaces, front and trailing edge surfaces and two ends are provided for insertion into aligned slots in headers to complete a heat exchanger assembly. The tubes each include a first coating composition containing an adhesive binder vehicle, flux material and brazing alloy deposited on the side surfaces adjacent the ends of the tube. The first coating composition is structurally arranged and applied to engage the aligned slots in the headers upon the insertion of the ends of the tubes into the header. The side surfaces of the microextruded tube include a second surface coating containing an adhesive binder vehicle, flux material, zinc and silicon extending the length of side tube between the deposited first coatings. The front and trailing edge surfaces of the tube include a third surface coating composition containing adhesive binder vehicle, flux material and zinc. A method of manufacturing parallel flow-type heat exchangers is disclosed.
