1 Claim

1. A supercritical cooling regulator (SuCCoR): comprising of a plurality of sub-systems, including:

a sealed fluid tank with the cooling fluid, which is a refrigerant, maintained at a pressure in a vicinity of the supercritical pressure (P_C) of the cooling fluid, wherein the cooling fluid is in a supercritical state at a temperature to which a device is exposed to;

the device includes one or more of battery pack(s), a smart-grid, a transformer, and/or some heat generating mechanical, electrical, and/or electronic device that needs to be cooled;

the cooling fluid in its supercritical state is an electrical non-conductor but a good heat conductor, which prevents electric short-circuit of the device, which is immersed in the cooling fluid;

the cooling fluid in the supercritical state is distinct from having liquid and gas phases;

the cooling fluid in the supercritical state will not undergo evaporation or condensation;

an optional pressurization valve to raise the fluid pressure to above the critical pressure P_Cof the cooling fluid if necessary;

an optional pressure safety valve to release excess fluid pressure and maintain safe pressure levels during operation;

optional sensors to monitor the pressure and temperatures of the cooling fluids in the inner sealed fluid tank and outer jacketed vessel;

an optional heater to heat the cooling fluid during cold weathers to keep the device at optimal operating temperatures;

an outer jacketed vessel around the cooling fluid tank to hold a high thermal conductivity and high specific heat fluid to enhance the cooling ability by holding the heat removed by the supercritical fluid in the sealed fluid tank, at a lower overall temperature because of its high specific heat capacity;

an optional network of cooling fins and thermally conducting pipes to carry cooling fluids in the sealed inner fluid tank and the outer jacketed vessel;

an optional fluid mixer to stir the fluid;

for which cooling fluid pressure in the sealed tank remains stable for many months of time;

for which there is no limitation and/or constraint on the dimensions and geometry of the device that can be cooled; and

for which heat generated by the device, which is immersed in the cooling fluid, is transported towards cooler tank walls via efficient molecular level conduction and convection processes.
