Electricity-magnetic energy conversion
The present invention adopts the annular magnet of high permeability to produce magnetic field, and because the magnet permeability adopted is high, little number of turn can obtain very high inductance value, so main energetic is all converted into magnetic field energy in whole electricity-magnet ring energy, the copper loss of coil is minimum.In structural design of the present invention, the closed magnetic field formed by the carbon steel of better magnetization characteristic is defined around solenoid, because the permeability of carbon steel is far above the liquid medium of surrounding, so almost magnetic field energy is compressed among the closed magnetic field that carbon steel formed.Therefore in electricity of the present invention-magnetic energy transfer process, there is very high conversion efficiency, hardly off-energy.Even if coil copper loss, caloric value is also limited in heater inside, and the heat produced is also by the utilization that can't harm.
Meanwhile, owing to adopting the Electromagnetic Design of low copper loss, the caloric value of coil inside is very little, so very little by the temperature difference of heating liquid in coil and calandria, coil is in lower operating temperature always, overcomes the calandria life problems of direct electro heating, possesses higher reliability.
And due to the coil turn of inside few, internal resistance is low, and inductance value equiva lent impedance is main reactance parameter, and the current/voltage phase difference of generation is fixed, power factor up to more than 0.97, without the need to allocating power factor comparatively equipment.
Magnetic energy thermal power transfer
The present invention is based on magnetic field in intrametallic eddy-current heating principle, the magnetic field of electromagnetic inductance generation is closed among the toroidal magnetic field of carbon steel formation, the magnetic field be coupled in carbon steel body causes carbon steel inside to produce eddy current, utilizes the eddy-current heating of carbon steel, produces heat heating liquid.
In conjunction with technology such as Optimizing design, fluid flow control, flow path of the liquid control, magnetic energy conversions in the present invention, carry out magnetic Circuit Design, ensure that magnetic energy is not lost in outside heater, the heat energy of heater conversion simultaneously can be delivered in liquid by efficient transmission.
Metal-liquid heat transmits
Liquid, after entrance enters, first absorbs the heat transmitted from inside to outside at preheating channel 2, be also the effect serving heat-insulation layer simultaneously, fully absorbed in liquid by heater institute conversion heat, prevent heat loss; Liquid through preheating completes heating by the thermal treatment zone.Overall heater is bathed among liquid substantially, both ensure that heater heat is break-even and has exchanged by among heating liquid, and liquid is also for heater has carried out abundant cooling simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
