There is provided it is a kind of by the variable-frequency electromagnetic heating device for heating with reasonable winding mode, thus further increase heating effect
Rate improves the service life of heating device.
To achieve the above object, the utility model uses following technical scheme:
A kind of variable-frequency electromagnetic heating device for heating, comprising: including interior pipe fitting and outer tube member, the outer tube member suit
It on said inner tube part, is connected between said inner tube part and the outer tube member by partition, is wound with electromagnetic wire on the outer tube member
Circle, the electromagnetic coil are connect with frequency-variable controller, and outer plastic is located at outside the electromagnetic coil, and both ends and the outer tube member connect
It connects, the outer tube member is made of epoxy resin, and the electromagnetic coil is arranged in outer tube member in a manner of multiple coil units
On outer surface.
Further, the wire circle of each coil unit is 10 circles.
Further, the gap length of adjacent coil unit is 10mm~20mm.
The utility model has the beneficial effects that making the greatly pyromagnetic of an entirety using the coil canoe of the present apparatus
Field becomes several small magnetic fields, forms small vortex, so as to greatly reduce the self-heating amount of coiled wire-wound coil, especially may be used
The self-heating amount for greatly reducing coiled wire-wound coil in the middle part of outer tube member improves heating device to further increase heating efficiency
Service life.
