HEAT EXCHANGER TUBE SUPPORT

A heat exchanger (20) for heat exchange between a first fluid (910) and a second fluid (912) has a plurality of tube sections (40), each having; an interior for passing the first fluid (910); an exterior for exposure to the second fluid (912); a first leg (46); a second leg (48); and a turn (49) joining the first leg (46) to the second leg (48). The heat exchanger also has a support having: fiber members (204, 206, 230, 232) passing between the legs (46, 48) of the tube sections (40); and an end plate (224, 226, 244, 246).
