Abstract
The electromagnetic inductive air heater belongs to tube shape heating device. The supporting board is concentric parallel mounted in the insulated magnetic outer heating canister, and conducting magnetic inner heating tube is cross-under between the supporting boards, and the over current hole is arranged on the supporting boards for solving the problems of low heat efficiency of resistance wire type tube shape heating device and poor safe reliability. The periphery of the outer heating canister is provided with the thermal insulation layer, the inductance coil supporter and the inductance coil in turn. And the heat efficiency is larger than 80%. The surface temperature of the inner heating tube can obtain 800 DEG C, and the insulation property is high.
Description
Technical field
The electromagnetic induction air heating apparatus belongs to tubular heating device.
Background technology
Common tubular heating device generally is to place resistance wire to do calandria in steel pipe, and fill appropriate amount of quartz sand and do transmitting medium, because quartz sand is that a lot of air-gaps appear in loose arrangement, will could pass to air by the metal tube shell of heating at last simultaneously as conduction heat medium.Heat efficiency less than 60%, heat pipe surface temperature are generally 450 ℃～550 ℃.Also exist poor reliability, often have resistance wire to open circuit or ground short circuit, the outer casing electrification personal safety is endangered.
Summary of the invention
Low for solving the resistance wire formula tubular heating device heat efficiency, the deficiency of security reliability difference provides a kind of novel electromagnetic induction air heating apparatus.Technical scheme is: according to electromagnetic inductive heating principle, and concentric parallel installation supporting bracket in the cartridge heater outside non-magnetic, the interior heating tube of cross-under magnetic conduction between the supporting bracket, supporting bracket is provided with flowing hole.Outer cartridge heater periphery is equipped with thermal insulation layer, inductance coil bracing frame, inductance coil successively.Alternating current produces the alternating flux of same frequency by inductance coil during work in interior heating tube, and alternating flux produces induced potential again in interior heating tube, cause electric current make in the heating tube heating, realize induction heating.Outer cartridge heater is a kind of non-magnetic metal, heats when inductance coil forms short circuit current in the cartridge heater during by alternating current outside, thereby has possessed the efficiency of heating surface of inside and outside concord.The a large amount of losses of heat energy in medium in the energy conduction have been reduced.The heat efficiency is greater than 80%, and interior heating tube surface temperature can reach 800 ℃, the insulation property height.
