摘要：A heat exchanger which is constructed such that combustion gas passages 4 for passage of combustion gas and air passages 5 for passages of air are arranged alternately, and the heat exchanger is cut at one end side thereof in an unequal angle configuration to form combustion gas passage inlets 11 and air passage outlets 16, and cut at the other end side thereof in an unequal angle configuration to form combustion gas passage outlets 12 and air passage inlets 15. the combustion gas passage inlets 11 and combustion gas passage outlets 12, through which a combustion gas having a larger volume flow rate passes, are formed on a long side of an angle, and the air passage inlets 15 and air passage outlets 16, through which an air having a smaller volume flow rate passes, are formed on a short side of an angle. Accordingly, it is possible to avoid an increase in pressure loss caused by a volume flow rate difference between a high temperature fluid and a low temperature fluid to reduce pressure loss in the entire heat exchanger.
