Abstract:
1. A fuel conveying device for conveying fuel to an engine, comprising: a filter housing having a fuel inlet and a fuel outlet; a metal cap attached to the filter housing wherein the metal cap is made of a material having a high thermal conductivity of at least about 100 W/mk; a lid attached to the metal cap, the lid having at least one cooling fin which has a cooling surface exposed to an exterior of the filter housing; an annular fuel filter disposed wholly within the filter housing; a casing received within the filter housing, the casing enclosing an electronically commutated brushless motor and a fuel pump, the casing also having a fuel inlet port and a fuel outlet port, the fuel inlet port communicating with the fuel inlet of the filter housing, wherein fuel passes into the fuel inlet port before passing through the annular fuel filter; and control electronics for the electronically commutated brushless motor received within the metal cap in direct conductive heat transfer relationship with the at least one cooling fin, wherein the control electronics are enclosed at least in part by the metal cap to isolate the control electronics from exposure to fuel.
