WIND HEAT GENERATOR Russian patent published in 2003 - IPC

FIELD: wind power engineering. SUBSTANCE: invention can be used for carrying out low-temperature thermal processes and also in agriculture, for instance, for drying grain using wind energy. Proposed wind heat generator contains wind turbine, multiplicator vertical shaft, heat generator consisting of friction and heat chambers and friction elements. According to invention, friction elements are cantilever mounted on radial spring-loaded telescopic rods on vertical shaft and are secured in upper part of friction chamber. Spring tension inside rods is adjusted by nuts, and friction elements are arranged over entire height of friction chamber for cooling it with air flow sucked in by centrifugal fan installed inside friction chamber in horizontal position through vent holes made in cover of heat generator. Air flow gets heated in flat coil located between heat and friction chambers and is directed along discharge pipe to consumer. Perforated blades are installed in heat chamber and are secured by flexible rubber sleeves on elongated rods mounted on vertical shaft. Heat chamber is provided with inlet branch pipe at the bottom and outlet branch pipe at the top to pass working liquid-heat carrier. Invention improves heat effect of heat generator, converts low potential energy of wind with small velocities at reduction of power losses. EFFECT: improved efficiency of wind heat generator. 3 cl, 5 dwg
