The Einstein–Szilard or Einstein refrigerator is an absorption refrigerator which has no moving parts, operates at constant pressure, and requires only a heat source to operate. It was jointly invented in 1926 by Albert Einstein and his former student Leó Szilárd, who patented it in the U.S. on November 11, 1930 (U.S. patent 1,781,541).

Internally grooved copper tube. Internally grooved copper tubes, also known as "microfin tubes", are a small diameter coil technology for modern air conditioning and refrigeration systems. Grooved coils facilitate more efficient heat transfer than smooth coils. [1] [2] Small diameter coils have better rates of heat transfer than conventionally ...
The heat necessary for the dilution is the useful cooling power of the refrigerator, as the process of moving the 3 He through the phase boundary is endothermic and removes heat from the mixing chamber environment. The 3 He then leaves the mixing chamber in the dilute phase. On the dilute side and in the still the 3 He flows through superfluid ...
