ABSTRACT:
A water separating apparatus for a fuel system comprises a reservoir and a heat exchanger disposed inside the reservoir. Through a heat exchange process, fuel flowing through the reservoir is heated to melt ice crystals in the fuel and to cause water contaminants in the fuel to precipitate from the fuel. The reservoir includes a coolant inlet, a coolant outlet, a fuel inlet and a fuel outlet, and has a flat side for mounting onto a flat mounting surface. Coolant lines connect the coolant inlet and the coolant outlet to a source of fluid bearing waste heat. The heat exchanger includes at least one tube running between the coolant inlet and the coolant outlet. The heat exchanger also includes an enclosure disposed so as to enclose a portion of the tube and define a pre-heat chamber. Openings in the enclosure provide communication between the fuel inlet and the pre-heat chamber, and between the pre-heat chamber and the fuel outlet. The outer dimensions of the reservoir are chosen such that the apparatus fits within a desired space in an engin compartment.
