Embodiment Construction
[0021] The existing electromagnetic heating technology of the induction cooker has been developed very maturely, and this technology is to heat the ferromagnetic heated body above through the insulating and high-temperature resistant flat plate through the disc-shaped electromagnetic coil. The electromagnetic heating heater made of electromagnetic heating technology, some structures welded on the surface of the heated body lead to a large heat loss between the disc electromagnetic coil and the ferromagnetic heated body, which affects the overall heat transfer of the electromagnetic heating heater. Thermal efficiency; moreover, since the disc-shaped electromagnetic coil and the heated body are respectively located on both sides of the insulated high-temperature-resistant flat plate, the magnetic field lines must pass through the insulated high-temperature-resistant flat plate to heat the heated body, so there must be electromagnetic leakage, and part of the electromagnetic energy...

The invention discloses an electromagnetic heating warmer, comprising a heat-transfer pipe made of a ferromagnetic material, an insulated isolating support frame and an electromagnetic coil, wherein the heat-transfer pipe is closed on the two ends and is vacuumized; liquid medium is filled inside the heat-transfer pipe and has the volume less than that of the heat-transfer pipe; the insulated isolating support frame is cylindrically sleeved on the outer wall at one end of the heat-transfer pipe; and the electromagnetic coil is cylindrically wound on the insulated isolating support frame. By using the heat-transfer pipe, the cylindrical electromagnetic coil wound at one end of the heat-transfer pipe and the insulated isolating support frame as core structural members, the electromagnetic heating warmer has simple structure and is easy to assemble; by adopting a tightly heating mode, the electromagnetic coil and the heat-transfer pipe have high electrothermal conversion and heat transfer efficiencies; and the whole warmer has the characteristics of compact structure, light weight and small size.
Description
technical field [0001] The invention relates to the field of heating equipment, in particular to an electromagnetic heating heater. Background technique [0002] The climate in the north is cold in winter, and people can use heaters to increase the indoor temperature. Common heaters include heaters such as resistance wire type, quartz type, and oil heater type, and the electrothermal conversion efficiency is below 70%. The low electrothermal conversion efficiency leads to high power consumption of these heaters, and there are also safety hazards such as electric leakage. [0003] Because the electromagnetic heating technology of the induction cooker has been developed very maturely, the electrothermal conversion efficiency of the electromagnetic heating can reach more than 85%, and the energy saving effect is obvious, so the existing electromagnetic heating heater continues to use the heating technology of the induction cooker. The current electromagnetic heating heater is...
