Example Embodiment

[0017] The present invention will be further described below with reference to the drawings and embodiments.
[0018] Such as figure 1 with figure 2 As shown, a thermal storage heat transfer oil heating system with a built-in electromagnetic heater of the present invention includes a thermal storage oil tank 1 with a thermal insulation layer 2, an electromagnetic heater, a heating device 12, and an electric control box, and is characterized by:
[0019] The electromagnetic heater is composed of a main electromagnetic heater 4 and an auxiliary electromagnetic heater 8.
[0020] The main electromagnetic heater 4 is arranged in a heat storage oil tank 1 with a heat insulation layer, and an oil-water heat exchanger 6 is also provided in the heat storage warm oil tank 1 with a heat insulation layer;
[0021] The main electromagnetic heater includes a magnetically conductive shell 4-2, a non-magnetically conductive support 4-1 and an electromagnetic induction coil 4-5 arranged at both ends of the magnetically conductive shell 4-2, and the electromagnetic induction coil 4 -5 is located in the sealed space formed by the magnetically permeable housing 4-2 and the non-magnetically permeable support 4-1, the terminal of the electromagnetic induction coil 4-5 extends out of the magnetically permeable housing 4-2 and has The outside of the heat storage temperature oil tank 1 of the thermal insulation layer is connected with the electric control box 9. A metal fin tube 4-3 is arranged outside the magnetic conductive shell 4-2, and the inner side wall of the magnetic conductive shell 4-2 is also coated There is an insulating film 4-4.
[0022] The magnetic conductive shell 4-2 is a cylindrical or square iron cylinder. The non-magnetically conductive support 4-1 is made of aluminum material and Teflon material, and other high-temperature plastic materials can also be used. The auxiliary electromagnetic heater 8 adopts an existing electromagnetic heater.
[0023] In the present invention, a water-cooled power tube radiator 10 is provided in the electric control box 9. The water inlet end of the water-cooled power tube radiator 10 is connected to the outlet pipe of the heating device 12, and the water-cooled power tube radiator The water outlet of 10 is connected with the water inlet of the auxiliary electromagnetic heater 8, the outlet of the auxiliary electromagnetic heater 8 is connected with the water inlet 7 of the oil-water heat exchanger 6, and the water inlet 13 of the heating device 12 is connected to the oil and water through the circulating water pump 14. The outlet pipe 15 of the heat exchanger 6 is connected. Use the heating device 12 to return to low temperature and return water to cool the power components in the control box through the water-cooled power tube radiator 10, remove the air-cooling system in the control box 10, and there is no fan noise during operation, which is environmentally friendly. The purpose of noise-free operation is to recover the heat generated when the power element is working and to the hot water supply system to further improve the overall conversion efficiency of electric heating.
[0024] The electromagnetic induction coil on the auxiliary electromagnetic heater 8 and the circulating water pump 14 are electrically connected to the electric control box 9 respectively.

[0026] The heat storage oil tank 1 with the heat preservation layer 2 of the present invention is provided with a fin-shaped metal heating element, and the heat storage oil tank 1 with the heat preservation layer 2 is filled with oil medium 3, and is placed in the heat storage oil tank 1 when the current passes through When the electromagnetic induction coil 4-5 of the electromagnetic heater is used, the electromagnetic induction coil 4-5 will generate a high-speed alternating magnetic field. Also, because there are multiple fin-shaped metal heating elements 4-3 on the outside of the electromagnetic heater, When the magnetic lines of force in the magnetic field pass through the magnetic shell and the metal fin tube 4-3, the magnetic shell and the metal fin tube 4-3 will generate countless small eddy currents, and the magnetic shell and the metal fin tube High-speed heat generation, so that the oil medium 3 in the heat storage oil tank 1 with the thermal insulation layer 2 uniformly and quickly stores and releases heat on both sides. This kind of heating electromagnetic heating not only has a fast heating speed; but also because the heating medium is oil, the heat dissipation speed is slow, and the peak shaving of the power grid can be used to fill the valley. During the trough period of the power grid, the electromagnetic heater will be activated to save the cheap trough electricity, wind power, Photoelectric and nuclear power are converted into thermal energy and stored, and the energy saving effect is very ideal. The hot oil is stored in a heat storage oil tank 1 with an insulation layer. It is possible to stop heating during peak electricity heating, heat oil during valley electricity, and then heat the water to the heating standard temperature through the oil-water heat exchanger 6, and then deliver it to the heating device of the heating user.
[0027] The thermal storage type thermal oil electromagnetic heating system of the present invention not only has fast heating speed, high thermal efficiency, but also has long service life, no pollution, and is safe and reliable.
