Abstract

A heat exchanger for using an evaporator of an automotive air conditioner comprises a plurality of tube units and a plurality of corrugated fins. A pair of plates are connected each other for forming the tube unit. The plate has an elongating portion at an outer peripheral of the connecting portion at which one plate is connected to another plate. The elongating portion elongates from the connecting portion to the corrugated fin, but there exists some gap between the elongating portion and the corrugated fin. So that a draining space is formed within the connecting portion and the elongating portion of the plate and the corrugate fin. Since no surface tension is occurred between the elongating portion and the corrugated fin, the condensed water introduced into the drawing space can be drained effectively.
