Patent number: 9827638Abstract: Each heat exchange tube of a condenser is formed of a first brazing sheet having a core material and a first brazing material covering the core material. The tank body of each header tank is formed of a second brazing sheet having a core material and a third brazing material covering the core material and being lower in flowability than the first brazing material. In a region of a surface of each protrusion portion facing the corresponding heat exchange tube, the region having a predetermined width as measured from the projecting end, the core materials of the two brazing sheets are brazed together by means of the first brazing material. In the region other than the brazed portion, the core materials of the two brazing sheets are brazed together by means of a fillet formed of a mixture of the first and third brazing materials.Type: GrantFiled: July 6, 2015Date of Patent: November 28, 2017Assignee: KEIHIN THERMAL TECHNOLOGY CORPORATIONInventors: Takahisa Saito, Kengo Chiba, Yoshinori Nakata
