Systems and methods for managing the heating of thermal fluids

A thermal management system comprising:

• a first fluid pump and a second fluid pump, the first fluid pump positioned for at least partial submersion in a first thermal fluid in a thermal fluid tank of a first thermal circuit, the second fluid pump positioned for at least partial submersion in a second thermal fluid in a first pressurized reservoir of a second fluid circuit;
• a first drive shaft coupled to a driver and the first fluid pump, the first fluid pump being operated by a rotational displacement of the first drive shaft by the driver, the first fluid pump being configured to provide a first force to circulate the first thermal fluid through the first fluid circuit, a second portion of the first drive shaft positioned in an interior area of the first thermal fluid tank, a first portion of the first drive shaft being positioned outside of the thermal fluid tank and not directly physically attached to the second portion of the first drive shaft;
• a second drive shaft coupled to the second fluid pump and coupled to the first portion of the first drive shaft by a clutch, the second fluid pump being operated by a rotational displacement of the second drive shaft to provide a second force to circulate a second thermal fluid at least through a heat exchanger of the second fluid circuit positioned in the thermal fluid tank;
• and
• a magnetic coupling having a first portion and a second portion, the first portion of the magnetic coupling attached to the first portion of the first drive shaft and positioned outside of the thermal fluid tank, the second portion of the magnetic coupling coupled to the second portion of the first drive shaft and positioned in the interior area of the thermal fluid tank;
• wherein the magnetic coupling transfers a force between the first and second portions of the magnetic coupling to rotatably displace the first portion of the magnetic coupling, and thereby rotate the second portion of the second drive shaft, with the rotational displacement of the first portion of the magnetic coupling as the first portion of the first drive shaft is rotably displaced by operation of the driver, and
• wherein the clutch is selectively displaceable from an engaged position at which the rotational displacement of the first portion of the first drive shaft is transmitted by the clutch to facilitate the rotational displacement of the second drive shaft, and a disengaged position at which the rotational displacement of the first portion of the first drive shaft is not transmitted by the clutch to facilitate the rotational displacement of the second drive shaft.
