Abstract
A thermal management unit for a vehicle powertrain component. The thermal management unit is designed to maintain the operating temperature of the vehicle component within a relatively small, ideal temperature range. The thermal management unit includes a three-way valve and temperature sensor that uses the temperature of a lubricant used by the component itself to configure the valve such that lubricant having the desired temperature is passed to the component.
Claims21
A thermal management unit for a vehicle powertrain component, said thermal management unit comprising:
- a temperature controlled multi-port valve having a sensor adapted to sense a temperature of a lubricant used by the powertrain component, said valve having at least a first configuration during a first state whereby heated lubricant is passed to the powertrain component and a second configuration during a second state whereby cooled lubricant is passed to the powertrain component based on the sensed temperature;
- and
- means for heating and cooling the lubricant.
An engine cooling system comprising:
- a radiator;
- a pump adapted to input engine coolant from the radiator and to pump the coolant to an engine;
- and
- a thermal management unit for managing the temperature of a vehicle powertrain component, said thermal management unit comprising:
- a temperature controlled multi-port valve having a sensor adapted to sense a temperature of a lubricant used by the powertrain component, said valve having at least a first configuration during a first state whereby heated lubricant is passed to the powertrain component and a second configuration during a second state whereby cooled lubricant is passed to the powertrain component based on the sensed temperature;
- and
- means for heating and cooling the lubricant.
