ABSTRACT:
A coolant pump system driven initially by an electric motor in-line with the pump shaft to the pump housing incorporates a ram air-assisted cooling system. The ram air-assisted cooling system includes an electric motor whose rotating shaft drives the primary fan member. A second fan member is located about and connected to the periphery of the primary fan member and is rotated by high velocity air streams purposefully directed at the secondary fan blades. The air which drives the secondary fan member is preferably gathered by one or more air inlet funnels. Typically, two air inlet funnels are equiangularly disposed adjacent the periphery of the secondary fan blade members so that a balanced current of air is swept across the secondary fan blades. A shroud extends over the secondary fan blade members to force the inlet air over the fan blade members.
