<p>A brazed tube assembly and a joining method thereof using brazing, are disclosed. The tube assembly using brazing includes a pre brazed joint assembly method to form a fully pre assembled and locked component prior to brazing. This involves a metal tube with a binding bent portion which is disposed at a lower portion of the basic metal tube bound using brazing to be bent toward an outer periphery, a connecting part to form a binding installation portion with an installation bent portion which is disposed at an upper portion of the connection tube to be bent toward an outer periphery to install the binding basic metal part of the basic metal part, and to form a combining projection upward at an outer end portion of the binding installation portion, and a binding part to form a wetting space at an upper end portion of the binding bent portion of the basic metal part which is in surface contact with the combining projection, wherein filler metal is heated for wetting in a gap between the connecting part and the basic metal part in an installation state to form a filler metal layer which binds the basic metal part and the connecting part.</p> |
