Abstract

The invention relates to a wind heating device based on a magnetorheological effect and a heating method thereof. The wind heating device comprises a transmission shaft, rolling bearings, a bearing pedestal, a heating barrel cover, a heating barrel body, a heat exchange part, a heating rotor, electromagnetic coils and a magnetorheological intelligent material and is characterized in that a closedheating barrel is full of the magnetorheological intelligent material, the electromagnetic coils are installed on the outer all of the heating barrel, when weak currents are introduced into the electromagnetic coils, the yield stress of the magnetorheological intelligent material proportionally changes according to the intensity of exciting currents, and a hindering effect is achieved on rotationof the heating rotor. The wind heating device has the advantages that conversion from mechanical energy to heat energy is achieved through the magnetorheological effect; the yield stress of the magnetorheological intelligent material is linearly changed by changing the exciting currents, and then the heating efficiency and the heating rate of the wind heating device are easy to control and convenient to improve; and when the exciting currents reach a certain threshold value, the wind heating device is converted into a brake, and overspeed protection on a whole wind heating system can be achieved.

Description

technical field [0001] The invention relates to a wind heating device, in particular to a wind heating device based on magneto-rheological effect and a heating method thereof. Background technique [0002] In areas with higher latitudes, wind energy resources are relatively abundant in autumn, winter, and early spring. Wind energy can be converted into heat energy and used for indoor heating, heating of livestock and poultry houses, greenhouses, aquatic product breeding rooms, cleaning and maintenance of milking equipment. Disinfection, drying of agricultural products and other occasions can help save conventional energy consumption, and it is one of the effective ways to solve the shortage of production and living energy. [0003] In the past 35 years, Japan, the United States, the Netherlands, the United Kingdom, Denmark, Germany, Finland and other countries have successively carried out research on wind heating, and some wind heating technologies have entered the practica...
