COOLING MACHINE INCLUDING SEVERAL HEAT PIPES Russian patent published in 2008 - IPC F25B1/00 F25B27/00 

FIELD: cooling equipment, particularly to recover secondary heat energy resources and low-potential heat power from natural source.

SUBSTANCE: cooling machine comprises power unit and cooling unit. Power unit includes body receiving serially arranged evaporative chamber, working chamber and condensation chamber connected with each other. Working chamber is filled with wick. Condensation chamber is also provided with wick and is in contact with cold medium. Cooling unit has body receiving low-temperature evaporative chamber and compression condensation chamber. The receiving low-temperature evaporative chamber and compensation condensation chamber are separated one from another with case in steam space and are in liquid communication with each other through wick capillaries and in gas communication with each other through compressor. Compressor has rotor put on shaft. Pressure pipe is arranged in compression condensation chamber. Suction pipe is installed in low-temperature evaporation chamber. Evaporation chamber includes evaporation cases. Condensation chamber has condensation cases. End wall of low-temperature evaporation chamber is communicated with evaporation cases through orifices. Inner evaporation case surfaces are covered with porous strips, which define grooves. Wick strips are connected with wick core through lifting wicks. Lifting wick surfaces are cased from low-temperature evaporation chamber side to create throttling zone.

EFFECT: increased power and cooling efficiency.
