Abstract

An eddy-current heater operates by moving a permanent magnet (1) past an iron cylinder (5) of a given thickness. The generated eddy currents will dissipate their energy completely into heat which is transmitted to the surrounding water jacket (6) by conduction. The rotating shaft (2) carrying the magnet (1) is wind driven. The dimensions of the heater is determined by the shaft speed for a given magnetic flux density in the air gap between the magnet and the iron cylinder. This heater can be used for supplementing the work of solar heaters of domestic and general heating purposes. <IMAGE>

Description

Wind- Driven Eddy Current Heater.
This inveritiori relates fb wind-power heat 1 rig system.
Wind-power heating syst.ems is riow being seriously investigated where it is est@mated that 40 percent of a typical home's @nergy use is for water and space heatang.
Water churn, a device that relies on mechanically produced friction to raise water temperature, is tr@ed as a heating unit. Regulated and unregulated wind-power electric generator is another well-knowrl technique. Such system, however, are either bulky or relatively complex arid expensive.
The present invention is a simple wind-powered eddy-current heater which is a substitute to the wlnd- powered electric generator. Ihe electric generator, used for heating purposes operates by moving magnet past coils of wire then the generated electric energy Is dissipated as a heat I in ari electric resistance. While this proposed eddy-current heater operates by moving a magnet past a solid iron cylinder. Ihis method eleminates the need for coils, electric resistance and other components of the electric generator which iriturri reduces the cost of the system and increases its effieiency. The wind-driven magnet produces electric currents (eddy) in the conductive iron cylinder according to Faraday's law.These eddy currents will dissipate their energy completely as a heat in the iron cylinder where it is transmitted to the surrounding water through conduction. The amount of heat generated i ri the irori cylinder is a functi ori of the rotor shaft spied, magnetic flux density iri the air gap arid the dimensions of the iron cylinder. A lowcost device car be designed by trading off. the above factors and by choosing the appropriate electric and magnetic characteristics (resistivity and pereamability) of the iron of the cylinder.
The invention will row be described with reference to the accompanying drawings. Fig. 1 shows the winddriven eddy current heater supplementing the solar pariels for the heating of a house. Fig. 2-a,b show the three dimensional and the side view of the eddy current heater.
The heater comprises a magnet (1) mounted on the rotating shaft (2) which is drive by cross-wind axis rotor. The magnet could be a permanent magnet or an iron alloy which can be magnatized periodically. As the magnet rotates inside the solid iron cylinder (5) all the available wind energy is converted to heat in the cylinder due to the generated eddy currents.
The water to be heated enters the water jacket (6) throngh the inlet (7) which is located at the lower side of casing (8) and leaves from the outlet (9) located at the upper side of the casing The two covers (10) arid (11) are used to support the rotating shaft by mraris of ball bearing (3) arid thrust bearing (4) also the covers allow the alogmeiit of -magnet I inside the iron cylinder.

Claims (2)

1) The wind-driverl eddy current heater consists of a magnet mourited on a rotating shaft inside an iron cylinder of a given thickness. Due to the rotation of the magnet ari electric currents (eddy) in the conductive iron cylinder is produce@ according to Faraday's law. these eddy currents will dissipate their energy completely as a heat in the iron cylinder where it is transmitted to the surrounding water through conduction.
2) The heater claimed in 1 can be connected in parallel with solar heater for heating purposes.
