Abstract
The utility model relates to a kind of high-frequency electromagnetic and adds hot air device, metal inner pipe inwall adds one deck fin, make to increase with the contact area of air, temperature transmission is faster, make the air heat in metal inner pipe in a short period of time, also heat-insulation layer is provided with in the outside of coil, too much the leaving of the temperature preventing coil from giving out, also increase crust in outside in addition, warm air more than also existing is imported air blast by recovery tube, recycle, short by the frequency converter Electromagnetic Heating heating-up time, efficiency is high, add the effect of insulation, the utility model structure is simple, reasonable in design, workable, be worthy to be popularized.
Description
Technical field
The utility model relates to heating system technical field, and a kind of high-frequency electromagnetic particularly relating to dryer field adds hot air device.
Background technology
Existing dryer, about adding in hot-air prior art, has electrical heating and combustion heating two kinds of modes, and combustion heating needs could obtain clean hot-air with heat exchanger, and the thermic load that heat exchanger bears is comparatively large, and easily burn, the life-span is short, and the thermal efficiency is low; And the resistance heated efficiency of transmission is low, the life-span is short, and the heating-up time is long, have impact on the effect of drying insulation, is unfavorable for the popularization of product.
Utility model content
In order to solve the technical problem of above-mentioned existence, the utility model provides a kind of high-frequency electromagnetic and adds hot air device, and concrete technical scheme is:
A kind of high-frequency electromagnetic adds hot air device, comprise air blast, metal inner pipe, described metal inner pipe comprises import, outlet, pipe entrance point in described blower outlet connection metal, it is characterized in that: described metal inner pipe inwall is welded with fin, described metal inner pipe external rings is wound with coil, described coil is connected with controller, one layer of heat preservation layer is also provided with at coil skin, described heat-insulation layer skin is also provided with crust, space is had between shell and heat-insulation layer, louvered air inlet is had above described shell, below is offered openning and is connected recovery tube, described recovery tube is connected with blower inlet.
Described fin is welded on the inwall of metal inner pipe along the axial linearly shape of metal inner pipe.
Described fin is welded on the inwall of metal inner pipe along the axial helically shape of metal inner pipe.
The utility model compared with prior art has following technique effect: on metal inner pipe inwall, add one deck fin, heat exchange area is increased, heat up faster, also heat-insulation layer is provided with in the outside of coil, prevent thermal losses, also increase crust in outside in addition, make the air entering blower fan first by carrying out preheating between heat-insulation layer and shell, realize heat recovery, by in high-frequency electromagnetic heating process, coil itself can not generate heat, life-span is long, heating-up time is short, add the effect of insulation, the thermal efficiency is high, the utility model structure is simple, reasonable in design, workable, be worthy to be popularized.

Detailed description of the invention
Below by specific embodiment, and by reference to the accompanying drawings 1,2,3, the technical solution of the utility model is described in further detail.
A kind of high-frequency electromagnetic adds hot air device, comprises air blast 1, metal inner pipe 2, and described metal inner pipe 2 comprises import 9, outlet 8, the entrance point 9 of pipe 2 in the air outlet connection metal of described air blast 1.
Described metal inner pipe 2 inwall is welded with fin, described fin can have two kinds of forms in the shape of metal inner pipe 2 inwall, fin 7 as described in Figure 1, along metal inner pipe 2 axially linearly shape be welded on the inwall of metal inner pipe 2, also can as described in accompanying drawing 3 in fin 8 along metal inner pipe axially helically shape be welded on the inwall of metal inner pipe.
Described metal inner pipe 2 external rings is wound with coil 3, described coil 3 is connected with controller (not marking in figure), one layer of heat preservation layer 4 is also provided with at coil 3 skin, described heat-insulation layer 4 skin is also provided with crust 5, space is had between shell 5 and heat-insulation layer 4, have louvered air inlet above described shell 5, below is offered openning and is connected recovery tube 6, and described recovery tube 6 is connected with the air inlet of air blast 1.
In this structure, metal inner pipe inwall is provided with fin, adds heat exchange area, programming rate is faster, is also provided with heat-insulation layer in the outside of coil, reduces heat and distributes, also increase crust in outside in addition, making the air entering blower fan first by carrying out preheating between heat-insulation layer and shell, realizing heat recovery, by in high-frequency electromagnetic heating process, coil itself does not generate heat, and the life-span is long, and the heating-up time is short, add the effect of insulation, the thermal efficiency is high.
The above; be only this practicality preferably detailed description of the invention; but the utility model protection domain is not limited thereto, is equal to according to the technical solution of the utility model and inventive concept thereof and replaces or change, all should be encompassed within protection domain of the present utility model.
