Natural circulation type variable-frequency electromagnetic heating device

Abstract

The invention discloses a natural circulation type variable-frequency electromagnetic heating device. The natural circulation type variable-frequency electromagnetic heating device comprises a heat source generating device, a heat exchanging device, temperature sensing probes and a control system, wherein the temperature sensing probes are arranged on the heat source generating device and the heatexchange device respectively, the heat source generating device is connected with the heat exchange device by a circulating pipe with a heat conduction oil, and the heat source generating device, theheat exchanging device and the temperature sensing probes are electrically connected with the control system. According to the natural circulation type variable-frequency electromagnetic heating device, a variable-frequency electromagnetic heating pot body is heated by utilizing a variable-frequency electromagnetic induction principle, and the heated heat conduction oil can be circulated in a heat preservation tank body by combining the atmospheric pressure in the natural process, so that not only is energy saved greatly, but also the heat conduction area is increased, and the heat conductionefficiency is improved.

Description

technical field [0001] The invention relates to the technical field of frequency conversion electromagnetic heating devices, and more specifically relates to a natural circulation type frequency conversion electromagnetic heating device. Background technique [0002] At present, the known heaters include electric heaters, fuel oil, gas and steam heaters, but the electric heaters are directly heated by resistance, which not only has a slow heating speed, but also has high energy consumption and low thermal efficiency; Finally, it provides heat energy for the heater, but it needs to continuously replenish fuel to continue to provide heat, resulting in the consumption of a large amount of fuel resources, high energy consumption and production costs; gas heaters, like fuel heaters, need continuous replenishment Only gas can continuously provide heat, which leads to the consumption of a large amount of gas resources, and the energy consumption and production cost are also high; t...
