Abstract
A process for cooling a heat generating component of a vehicle including pumping a coolant fluid from a pump having a first impeller and a second impeller, the pump switchable from a chilling mode, a heating mode, an isolated state, and a linked state; and while the pump is in the chilling mode and the isolated state, pumping the coolant fluid with the first impeller through a first loop of a heater module, and a cabin heat exchanger, and pumping the coolant fluid with the second impeller through a second loop of a component heat exchanger and a chiller module.

A process for cooling a heat generating component of a vehicle comprising:
- pumping a coolant fluid from a pump having a first impeller and a second impeller, the pump switchable from a chilling mode, a heating mode, an isolated state, and a linked state;
- and while the pump is in the chilling mode and the isolated state, pumping the coolant fluid with the first impeller through a first loop comprising a heater module, and a cabin heat exchanger, and pumping the coolant fluid with the second impeller through a second loop comprising a component heat exchanger and a chiller module.
An apparatus for cooling a heat generating component of a vehicle comprising:
- a first loop comprising a heater module and a cabin heat exchanger;
- a second loop comprising a component heat exchanger and a chiller module;
- a pump having a first impeller and a second impeller, the pump switchable from a chilling mode, a heating mode, an isolated state, and a linked state;
- and, wherein when the pump is in the linked state the second impeller is in direct downstream communication with the first impeller, and when the pump is in the isolated state the first impeller pumps a coolant fluid through the first loop.
