Abstract
An apparatus and coolant pump for use in a thermal management system includes a pump housing having an inlet for receiving coolant from the thermal management system and at least first and second outlets extending from the pump housing for directing coolant to at least a first and a second coolant loop. An impeller coupled to an electrical pump motor drives the coolant from the inlet to the first or the second outlet. A valve mounted between the impeller and the first and second outlets selectively directs the flow of coolant through the first or the second outlet. A temperature sensor installed on the pump housing inlet measures the temperature of the coolant entering the coolant pump.
Claims10
An apparatus for cooling a heat generating component of a vehicle, comprising:
- a first loop comprising a component heat exchanger and a chiller module;
- a second loop comprising a heater module and a cabin heat exchanger;
- a first pump arranged to provide adjustable flow rates having an inlet attached to the heat exchanger configured to receive coolant from the heat exchanger;
- a valve located in the first pump configured to switch between a chiller mode and a recirculation mode, the first pump pumping the coolant from the inlet to the first loop in the chiller mode or between the inlet and the second loop in the recirculation mode;
- and
- a second pump arranged to provide adjustable flow rates;
- a valve located in the second pump configured to switch between an isolated mode and a linked mode, the second loop in downstream communication with the second pump while in the isolated mode, and the first loop in downstream communication with the second pump while in the linked mode;
- and
- a first temperature sensor installed on the first pump inlet that measures the temperature of the coolant entering the first pump, wherein the first temperature sensor signals a controller that operates the valve into the chiller mode or the recirculation mode and adjusts the flow rate of the first pump.
