ABSTRACT:
According to the present invention, the tube element includes a connecting portion for connecting the pair of core plates at an upstream air side, an extending portion extending from each of the connecting portions of the core plate at the upstream air side and having a fin connecting portion connected to the corrugated fin, and a further upstream end portion of the extending portion located at an upstream side of the fin connecting portion which is located away from the corrugated fin to form a predetermined gap with the corrugated fin so as to communicate with the air passage. The extending portion including the fin connecting portion closes the whole space between the tube elements and the adjacent corrugated fins at the more upstream air side of the refrigerant passage, so that the air entering between the tube elements and the adjacent corrugated fins can be substantially shut off.
