<p><P>PROBLEM TO BE SOLVED: To provide a heat exchanger that can fix a fin and a heat transfer tube using adhesive while maintaining adhesiveness of an initial stage of assembling a heat release fin and the heat transfer tube, and to provide a fin for the heat exchanger and a method for manufacturing of the heat exchanger. <P>SOLUTION: The heat exchanger 100 includes: the heat transfer tube 2 and a fin 3 for exchanging heat between medium passed through the heat transfer tube 2 which is perpendicularly attached to the axis direction of the heat transfer tube 2. The fin 3 has an opening 32 to attach the heat transfer tube 2, and a part surrounding the heat transfer tube 2 of an edge of the opening 32 has a fin collar 33 projecting to the axis direction of the heat transfer tube 2. The fin collar 33 and the heat transfer tube 2 are temporary fastened by welding. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
