Abstract
A heat exchanger includes a pair of header pipes, each having an end closed by a header cap; a plurality of heat transfer tubes interconnecting the header pipes; a plurality of fins; a side fin disposed on the outer surface of at least one of the outermost heat transfer tubes; and a side plate disposed on the outer surface of the side fin. The header cap comprises a header pipe connecting portion and a portion extending toward the side fin and side plate and having a concave portion engaged with the side fin and side plate. The header pipe and the side fin and side plate are connected to each other by the header cap; in particular, by the extended portion of the header cap, when assembled and brazed. The rotational shifting of the header pipe and the positional shifting of the side fin and side plate in the brazing process are prevented by the structure of the header cap.
