COOLING PLANT WITH OPPOSITE STIRLING THERMAL ENGINE Russian patent published in 2012 - IPC F25B9/14 

FIELD: instrument making.

SUBSTANCE: cooling plant with opposite Stirling thermal engine includes cavities for heat removal from cooling chamber, which are formed on heat-removing side of the plant, and heat transfer cavities on heat-transferring side of the plant. Cooling plant is equipped with four sealed capsules and two counter-flow gas heat exchangers with two connecting pipelines in each flow. Each of the capsules encloses cavities for heat removal from cooling plant, which are formed with cylinders and pistons on heat-removing side of the plant. Heat transfer cavities to cooling radiator, which are formed with cylinders and pistons on heat-transferring side of the plant, are located in capsules opposite to heat removal cavities. Also, each of the capsules encloses linear electric motors with movable element in the form of a through stock that rigidly attaches opposite pistons of heat-transferring and heat-removing sides of the plant. Cavities for heat removal from cooling chamber are connected via pipelines of heat exchangers flows, chambers of heat exchangers flows to heat transfer cavities on heat-transferring side of the plant. Inner space of chambers is filled with gas the composition of which is identical to gaseous working medium under pressure, which corresponds to average pressure value of working medium in thermodynamic cycle.

EFFECT: simplifying the design, reducing working medium losses and increasing the efficiency.
