Summary

ADVANTAGE CAN BE TAKEN OF THE SELF-STABILIZATION EFFECT ON TEMPERATURE, DURING MELTING OF A PURE SUBSTANCE AT ITS TRIPLE POINT. SELECTING A SUITABLE RATIO BETWEEN THE HEAT OF MELTING OF THE MASS OF THE SUBSTANCE AND THE HEAT EXCHANGE REQUIREMENT WITH THIS HEAT SINK, A MELTING PLATEAU CAN BE MAINTAINED WEEKS OR MONTHS, KEEPING TEMPERATURE STABLE WITHIN A MILLIKELVIN WITHOUT ANY SPECIFIC ENERGY SUPPLY. PLATEAU CONDITIONS CAN BE RESTORED AS MANY TIMES AS REQUIRED AND IN A SHORT TIME, WITH A SENSIBLE USE OF STRAY HEAT FLOWS ALREADY AVAILABLE IN THE VEHICLE. SEVERAL FIXED TEMPERATURES BETWEEN 14 AND 90 K CAN BE REALIZED.
