Abstract

A heat exchanger comprises concentric annular arrays of parallel feeder tubes and receiver tubes which are interconnected by generally circumferentially extending heat exchanger tubes. Each heat exchanger tube interconnects one feeder tube with a corresponding receiver tube which is angularly spaced apart therefrom. In operation a first fluid flows over the heat exchanger tubes while a second fluid flows through the heat exchanger tubes. The heat exchanger tubes are so arranged that the fluid flowing through them has a component which is opposite to that of the fluid flowing over them.
