Abstract
A process and apparatus for cooling a heat generating component of a vehicle comprises a first pump switchable between a normal demand mode and a high demand mode. Coolant is pumped from the first pump through a cooling loop between a heat dissipating device and the heat generating component at a normal demand flowrate in the normal demand mode. Switching the first pump to the high demand mode diverts the coolant to a second pump. The second pump pumping the coolant through the cooling loop at a high demand flowrate.
Claims20
A process for cooling at least one first heat generating component of a vehicle comprising:
- providing a first pump switchable between a normal demand mode and a high demand mode;
- pumping coolant from the first pump through a first cooling loop between a heat dissipating device and the first heat generating component at a first flowrate in the normal demand mode;
- switching the first pump to divert the coolant to a second pump in the high demand mode;
- and
- pumping coolant from the second pump through the cooling loop between the heat dissipating device and the at least heat generating component at a second flowrate that is greater than the first flowrate.
An apparatus for cooling a heat generating component of a vehicle comprising:
- a first coolant loop containing a heat dissipating device and at least one first heat generating component;
- a first pump for circulating a coolant through the first coolant loop between the heat dissipating device and the first heat generating component at a first flowrate;
- and
- a second pump fluidically connected to the first pump, the first pump switchable to divert the coolant from the coolant loop to the second pump,
- wherein the second pump circulates the coolant through the first coolant loop between the heat dissipating device and the first heat generating component at a second flowrate that is greater than the first flowrate.
The apparatus of 19, wherein in the second valve second position the second impeller pumps the coolant in the inlet chamber to the second pump outlet at the second flowrate.
