Centrifugal fluid separator
A vehicle system is provided. The system may include a first coolant loop, including a radiator, a second coolant loop including a battery chiller, and a centrifugal coolant separator. The centrifugal coolant separator may include a frustoconical hollow body having a base defining a drain and a ceiling defining a spout, and a pair of coolant lines arranged orthogonal to and on opposite sides of the body such that coolant exiting the lines travels along the inner surface and collects at the base to separate gas from the coolant, wherein the spout vents the gas and the coolant exits the drain.
1. A vehicle system comprising:
a first coolant loop including a radiator;
a second coolant loop including a battery chiller; and
a centrifugal coolant separator including:
a frustoconical hollow body having a base defining a drain and a ceiling defining a spout, and
a pair of coolant lines associated with the loops and arranged on opposite sides of the body such that coolant exiting the lines travels along an inner surface of the body and collects at the base for exit via the drain to separate gas from the coolant for venting via the spout.
2. The vehicle system of claim 1 further comprising a battery heat exchanger fluidly connected to the battery chiller and configured to receive coolant from the drain and provide coolant to the battery chiller.
3. The vehicle system of claim 1 further comprising a degas bottle configured to receive gas from the spout.
4. The vehicle system of claim 1 , wherein the pair of coolant lines are tangentially arranged to the inner surface.
5. The vehicle system of claim 1 , wherein the first coolant loop is disposed within a front-engine compartment and wherein the second coolant loop is disposed beneath a rear-trunk compartment.
6. The vehicle system of claim 1 , wherein the frustoconical hollow body includes a curved corner portion circumferentially extending around the base and extending between the base and a sidewall defining the inner surface.
7. A vehicle coolant system comprising:
a frustoconical hollow body having a base defining a drain and a ceiling defining a spout; and
a pair of coolant inlets arranged tangentially to an inner surface of the body such that coolant entering the inlets travels along the inner surface and collects at the base to separate gas from the coolant, wherein the pair of coolant inlets are connected to coolant lines within a battery coolant loop including a battery chiller that provides coolant to one of the coolant inlets, wherein the spout vents the gas and the coolant exits the drain.
8. The vehicle coolant system of claim 7 , wherein the frustoconical hollow body includes a curved corner portion circumferentially extending around the base and extending between the base and a sidewall defining the inner surface.
9. The vehicle coolant system of claim 7 , wherein the pair of coolant inlets are spaced away from the ceiling by a first distance and spaced away from the drain by a second distance less than the first distance such that a space within the body, extending along the first distance, accommodates the gas.
10. The vehicle coolant system of claim 9 , further comprising a pump disposed between the drain and battery chiller configured to move coolant from the drain to the battery chiller.
11. The vehicle coolant system of claim 7 , further comprising a radiator fluidly connected to the battery chiller and the other of the coolant inlets.
12. The vehicle coolant system of claim 7 , further comprising an electronics coolant loop including a degas bottle fluidly connected to the spout.
13. The vehicle coolant system of claim 12 , further comprising a radiator fluidly connected to an inverter system controller configured to provide coolant to one of the coolant inlets.
