Abstract
A supercharger cooling system provides a path for coolant from an air/coolant heat exchanger to a supercharger intercooler and then loops around the supercharger housing proximal to a hot outlet end of the supercharger and back to the heat exchanger. The heat exchanger may be a dedicated air/coolant heat exchanger or be a vehicle radiator. The intercooler is sandwiched between the supercharger and intake manifold and cools the flow of hot compressed air from the supercharger into the intake manifold. The supercharger cooling loop cools the bearings and seals, the forward ends of the male and female rotors, and the male and female rotor gears. The cooling loop is preferably located between the supercharger rotors and the rotor drive gears to form a barrier to heat. A dedicated pump cycles the coolant flow and restrictions control the flow of coolant to the supercharger.
