Abstract:
1. A heat exchanger for warming fuel prior to introduction of the fuel to an engine, the heat exchanger comprising: a fuel inlet, a fuel outlet, and a fuel inlet cavity located therebetween; a heat exchange matrix having heat transfer components past which the fuel flows between the fuel inlet cavity and the fuel outlet and which are arranged to be heated, the heat transfer components comprising radially inner fuel tubes and radially outer fuel tubes, the fuel tubes being located between the fuel inlet cavity and the fuel outlet; and swirl inducing means arranged within the fuel inlet cavity between the fuel inlet and the fuel tubes, the swirl inducing means causing fuel from the fuel inlet to swirl about an axis which is substantially parallel to the main direction of fuel flow through said fuel tubes prior to entering the fuel tubes to such an extent that the entrained ice concentrates in the radially outer fuel tubes.
