US Patent 7827969 Fuel supply device

The present invention provides a fuel supply device that can suppress the excessive heating of a fuel supplied from a fuel pump into an internal combustion engine even if a control module is cooled. The fuel supply device (1) comprises a set plate (10) attached to a mounting hole (34a) of a fuel tank (34), an electric fuel pump (30) attached to an inner surface of the set plate (10), a control module (14) attached to an outer surface of the set plate (10), the control module driving the fuel pump (30) using electric power supplied from the exterior, and a heat radiating member (32) for radiating heat generated in the control module. One end of the heat radiating member (32) is thermally connected to the control module (14), and the other end of the heat radiating member (32) protrudes downward from the inner surface of the set plate (10).
