Abstract
A liquid pump with a brushless motor constructed to be received within a liquid reservoir of a cooling system to deliver liquid coolant under pressure to a manifold assembly through which the coolant is discharged onto various electronic components to cool them. The pump has a pumping assembly, a rotor, a stator and an electronic control circuit which controls the operation of the pump and each of which is immersed in liquid coolant in the pump housing to cool them as the coolant flows through the pump. Further, because each component within the pump can be exposed to the liquid in the pump, no sealed enclosures are needed for the pump as a whole or for any component therein and the pump can be received directly in the reservoir.
