The inner coil and outer coil are respectively arranged on the centre position of internal layer isolating cylinder and outer layer isolating cylinder, interior layer line
The area coverage of circle and outer coil accounts for the 1/2-2/3 of internal layer isolating cylinder and outer layer isolating cylinder area respectively.
The central axes of the outer layer isolating cylinder and the axis line overlap of internal layer isolating cylinder.
The inner coil and outer coil wind equal turn numbers, and winding direction is identical.
The outer layer isolating cylinder and internal layer isolating cylinder are hollow structure.
The tube outlet and line entry are respectively arranged at the both sides of internal layer isolating cylinder.
The outer layer isolating cylinder and internal layer isolating cylinder are insulation system.
The inner coil surface is equipped with heat-insulating flame-retardant layer.
Having the beneficial effect that compared to the prior art of the invention：
The present invention produces high-frequency alternating magnetic field by being passed through high frequency electric to inner coil and outer coil, in fever wicking surface shape
Into vortex, make the temperature rapid increase of heat generating core, be passed through cryogenic media to the inside of heat generating core and take away heat, add so as to reach
The purpose of thermal medium.Heat generating core, which is designed as helical form, can be significantly increased metal heat generating core and need the contact area of heat medium,
Increase the time of media contact heat generating core, fully exchanged beneficial to heat, so as to fulfill the lifting of heating efficiency；Due to inside and outside layer
Coil produces high frequency magnetic field at the same time, and spiral helicine heat generating core can also increase the heated area of heat generating core, simultaneously because coil twines
It is identical around direction, it can also increase the field strength of unit area, contribute to temperature fast lifting.Ring flange is set by inside and outside isolating cylinder
It is fixed, ensure that gap is reduced between heat generating core and ring flange, reduce the heat losses in isolating cylinder, further lift electric heating conversion
Efficiency.Since the winding direction of inner-outer coil is identical, the magnetic flux of pipeline outer surface contact portion, increase heating effect can be increased
Fruit.The contact area of pipeline and heat medium can be substantially improved in the present invention in the useful space, extend adding in unit distance
The hot time, lifts heating efficiency, improves temperature rise speed.
