Abstract:
A system to cool a plurality of electronic components comprising:a reservoir containing a supply of a coolant; a pump having a brushless motor driving a pumping assembly constructed and arranged to draw the coolant from the reservoir into the pump and to discharge the coolant therefrom under pressure, the brushless motor having a stator, a rotor received in the stator and connected to the pump, and an annular space between the rotor and stator, an electronic control circuit electrically connected to the pump motor and responsive to a control signal to drive the motor and thereby drive the pumping assembly to discharge the coolant under pressure to flow through the annular space in direct contact with the stator and rotor and over the control circuit in contact therewith; and at least one manifold receiving the coolant under pressure downstream of the pump, stator, rotor, and control circuit and supplying the coolant under pressure to a plurality of outlets through which the coolant is discharged onto the electronic components.
