Heat exchanger having heat-exchanging core portion divided into plural core portions

A heat exchanger a width dimension of which is much larger than a height dimension, in which an heat-exchanging medium flow resistance in a heat exchanging core portion is suppressed from increasing, and discharged air temperature is made uniform in the width direction of the heat-exchanging core po...

Beschreibung
Zusammenfassung:	A heat exchanger a width dimension of which is much larger than a height dimension, in which an heat-exchanging medium flow resistance in a heat exchanging core portion is suppressed from increasing, and discharged air temperature is made uniform in the width direction of the heat-exchanging core portion. The heat-exchanging core portion is divided into a first core portion and a second core portion. The hot water in the first core portion and hot water in the second core portion flow in an opposite direction to each other. Thus, even when the heating heat exchanger, the width dimension of which is much larger than the height dimension, is used, the air temperature is prevented from varying in the width direction. Further, as the heat-exchanging medium flows in the first and second core portions in parallel, the heat-exchanging medium flow resistance is suppressed from increasing.
