HEAT EXCHANGING COIL ASSEMBLY AND COMBINED MEMBER

摘要

PURPOSE:To provide a heat exchanger capable of improving a heat exchanging capability without increasing the capacity of a body part. CONSTITUTION:A group of heat exchanging coils 8 are provided between an inlet side header 2 provided on an inlet pipe 4 and an outlet side header 3 disposed on an outlet pipe 5 so as to make both headers communicate and have a plurality of heat exchanging coils 9 whose winding diameters are different respectively and which are respectively surrounded by other heat exchanging coils 9 whose winding diameters are larger than those of the former.
