Abstract
The utility model discloses an electromagnetic heater including a support pipe and a heating assembly. The heating assembly is tightly sleeved on the support pipe, one end of the support pipe is provided with a fixing disc, a heating disc is arranged at the outer layer of the heating assembly, the interlayer is an electromagnetic induction coil, and a heat insulation sheet is arranged between the heating disc and the electromagnetic induction coil. Guiding by the heating principle of high-frequency electromagnetic induction coils, the electromagnetic coil is fixed on the support pipe and is directly placed into a heating medium, the electromagnetic induction coil enables the heating disc to vibrate under the effect of alternating current, the two sides of the heating disc generate an alternate magnetic field which is subjected to repeated cutting and changing, and then a circular current, namely, an eddy current is generated on the two sides of the heating disc; moreover, the heat generated by a small-resistance heavy-current short circuit heat effect directly makes the heating disc heating rapidly. Therefore, the electromagnetic heater provided is fast in heating speed, high in heat exchange efficiency, and energy-saving.
Description
Technical field
The utility model relates to a kind of liquid heating apparatus, is specifically related to a kind of electromagnetic heater.
Background technology
High-power electrical appliances of heating up water such as existing boiler, rice steaming car on the market, mostly adopt traditional resistance-type electric heater, its structure is that electric heating tube bank is arranged in the cylindrical shell, formed by electrothermal tube, protecting pipe and holder, resistance wire is arranged in the electrothermal tube, fill silica flour between resistance wire and electric heating tube wall, electrothermal tube places in the protecting pipe, protecting pipe is sealed at both ends, and the two ends with resistance wire in the end socket hole of cylindrical shell are connected with the cylindrical shell external power.Its principle of heating is to utilize the resistance of resistance wire to produce heat to heat, because electric current passes through conductor, conductor is to the inhibition of electric current, and will overcoming the resistance of conductor, electric current to do work, because transformation of energy is measured by acting, so how many merits electric current does, just there are how many electric energy conversions to become heat energy.
Utilizing electromagnetic induction principle to convert electrical energy into the kitchen appliance of heat energy modal is exactly electromagnetic oven, when electromagnetic oven in when normal operation, by rectification circuit the alternating voltage of 50Hz is become direct voltage, convert direct voltage to high frequency voltage that frequency is 20-40KHz through control circuit again, will produce alternating magnetic field on the coil disc of electric stove in the repeatedly cutting variation of pan bottom, making the pan bottom produce cyclic currents is eddy current, and utilize the short circuit thermal effect generation heat of the large electric current of small resistor that the bottom of a pan is generated heat rapidly, and then the thing in the heating appliances.The mode of heating of heat is given birth in this vibration, can reduce the intermediate link that heat transmits, and greatly improves heating efficiency.
But electromagnetic oven can not directly be immersed in the water and heat, could heat after needing to use container dress water, be inconvenient to be similar to the electrical equipment such as boiler, rice steaming car and directly contact water source heating and use, and resistance-type heat-generating pipe heating efficiency is low, energy consumption is high, the life-span is short, poor safety performance, easily produce incrustation scale.
The utility model content
The utility model provides a kind of can directly contact the water source, the electromagnetic heater that firing rate is fast, heat exchange efficiency is high, fail safe is reliable, the life-span is long.
The technical solution of the utility model: a kind of electromagnetic heater, comprise stay pipe and heat generating component, described heat generating component closely is socketed on the stay pipe; Described stay pipe one end is provided with fixed disk.
Described heat generating component skin is heat-generating disc, and the intermediate layer is electromagnetic induction coil, is the partiting thermal insulation sheet between heat-generating disc and the electromagnetic induction coil.
Described electromagnetic induction coil is that the high temperature lacquer envelope curve of multiply parallel connection holds and forms.
Described stay pipe is the straight pipe that stainless steel or ferroalloy are made.
Coil lead is drawn at described stay pipe two ends.
Technique effect of the present utility model: the utility model uses high-frequency electromagnetic induction coil heating principle, solenoid is fixed on the support tubes, directly insert in the heat medium, electromagnetic induction coil makes heat-generating disc produce vibration under the alternating current effect, the heat-generating disc two sides produces the alternating magnetic field that repeatedly cutting changes, making the heat-generating disc two sides produce cyclic currents is eddy current, and utilize the short circuit thermal effect generation heat of the large electric current of small resistor that heat-generating disc is generated heat rapidly, firing rate is fast, heat exchange efficiency is high, energy-conservation, the mode of heating of heat is given birth in simultaneously this vibration, can reduce the intermediate link that heat transmits, greatly improve heating efficiency, incrustation scale particulate and dust are difficult for being accumulated in the heat-generating disc outer wall.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, electromagnetic heater comprises stay pipe 1 and heat generating component 2 that the metal materials such as stainless steel or ferroalloy are made, and heat generating component 2 closely is socketed on the stay pipe 1, and stay pipe 1 one ends are provided with fixed disk 3; Heat generating component 2 skins are heat-generating disc 5, and the intermediate layer is that the high temperature lacquer envelope curve of multiply parallel connection holds and forms electromagnetic induction coil 7, is partiting thermal insulation sheet 6 between heat-generating disc 5 and the electromagnetic induction coil 7; Coil lead 4 is drawn at stay pipe 1 two ends.
Electromagnetic heater is to utilize electromagnetic induction principle to convert electrical energy into the heating electrical appliance of heat energy, electromagnetic heater is installed in to be filled with water maybe to be needed in the container of the liquid that heats, electromagnetic heater is when normal operation, by rectification circuit the alternating voltage of 50Hz is become direct voltage, convert direct voltage to high frequency voltage that frequency is 5-500KHz through control circuit again, will produce alternating magnetic field on the electromagnetic heater heat-generating disc 5 and repeatedly cut variation on heat-generating disc 5 two sides, making heat-generating disc 5 two sides produce cyclic currents is eddy current, and utilize the short circuit thermal effect generation heat of the large electric current of small resistor that heat-generating disc 5 is generated heat rapidly, and then the water in the heating container or liquid.
Heat-generating disc 5 can be according to watt level, and the serial or parallel connection wiring is installed, and the power of electromagnetic heater is larger, and the quantity of heat-generating disc 5 can be more, and area can be larger, and the wire diameter of electromagnetic induction coil 7 can be thicker, coil turn can be more; Power is less, otherwise then.
