Abstract (en)
[origin: EP1978322A2] A header (1010) for a heat exchanger comprising an inflow side (1018), an outflow side (1020), a bypass chamber (1052) therebetween, and a pressure-sensitive flapper valve (1146) proximal the bypass port. As pressure increases at the inflow side of the header, the flapper valve (1146) opens proportionally, and, as pressure decreases at the inflow side, the flapper valve (1146) closes proportionally. A tube-in-tube heat exchanger (2020) including a helical tube-in-tube assembly (2046) adapted for-flow therethrough of a plurality of fluids for heat transfer therebetween. A heat system including an embodiment of the header and an embodiment of the tube-in-tube heat exchanger, so as to provide a bypass of the tube-in-tube heat exchanger under a pressure condition.
