Eliminate faradic PTC heater device
Technical field
The invention belongs to PTC heater technical field, particularly relate to the faradic PTC heater of a kind of elimination
Device.
Background technology
Present stage all ptc heaters all can produce faradism, and prior art is mainly by adding metal screen layer
Eliminate faradism.Its method is that screen layer is connected with zero line around a circle metal screen layer in heater external rings,
There is insulating barrier to be separated by between screen layer and aluminum heat-delivery surface, make screen layer electromotive force be approximately zero, thus eliminate aluminum
The faradism on radiating piece surface.
During realizing the present invention, inventor finds that prior art at least there is problems in that but existing
Technology is when making the metal screen layer of parcel heater, and poor thermal conductivity, fault rate is high, and manufacturability is low.
Summary of the invention
The technical problem to be solved is to provide a kind of firing rate and improves, and heat conductivity increases, and manufactures
Technique simply eliminates faradic PTC heater device.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of elimination is faradic
PTC heater device, including PTC heater, described PTC heater includes the first battery lead plate, the second electricity
Pole plate, the first ceramic heating plate and insulating barrier, also include the 3rd battery lead plate and the second ceramic heating plate, described
First battery lead plate and the 3rd battery lead plate are connected with zero line, and described second battery lead plate is connected with live wire.
Including aluminum radiating piece, described aluminum radiating piece is hollow structure, is inside provided with heat radiation inner chamber, intracavity in heat radiation
It is provided with PTC heater.
Described second battery lead plate both sides are the first ceramic heating plate and the second ceramic heating plate, described first pottery
It is the first battery lead plate outside fever tablet, is the 3rd battery lead plate outside described second ceramic heating plate,
Coated insulation layer outside described first battery lead plate and the 3rd battery lead plate.
Being connected with zero line on described first battery lead plate, the 3rd battery lead plate, described second battery lead plate is connected with live wire.
Described PTC heater has two, lays respectively at water pipe both sides.
A technical scheme in technique scheme has the advantage that or beneficial effect, sends out with two potteries
Backing clamps the battery lead plate of line of starting to exchange fire, and the battery lead plate of another survey connecting to neutral line of two ceramic heating plates is close to,
Having insulating barrier to be separated by between connecting to neutral line electrode plate and aluminum radiating piece, such structure makes and aluminum radiating piece shell pair
The electrode answered is all the zero line close to ground potential, reduces electric potential difference between the two, thus eliminates aluminothermy part
Faradism.This structure two panels ceramic heating plate, and without excess metal screen layer, firing rate carries
Height, heat conductivity increases, and manufacturing process is simple.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to the present invention
Embodiment is described in further detail.
Seeing Fig. 1, the faradic PTC heater device of a kind of elimination, including aluminum radiating piece 201, aluminum dispels the heat
Part is hollow structure, is inside provided with heat radiation inner chamber 202, is provided with PTC heater 203, PTC in heat radiation inner chamber 202
Heater 203 includes first battery lead plate the 2, second battery lead plate the 4, the 3rd battery lead plate the 6, first ceramic heating plate
3, the second ceramic heating plate 5 and insulating barrier 1, the second battery lead plate 4 both sides are the first ceramic heating plate 3 and
Two ceramic heating plates 5, are the first battery lead plate 2 outside the first ceramic heating plate 3, outside the second ceramic heating plate 5
Side is the 3rd battery lead plate 6,
As in figure 2 it is shown, coated insulation layer 1 outside the first battery lead plate 2 and the 3rd battery lead plate 6;
First battery lead plate the 2, the 3rd battery lead plate 6 is connected with zero line, and the second battery lead plate 4 is connected with live wire.
Fig. 2 is the sectional view of PTC heater, and PTC heater comprises the first ceramic heating plate 3, second and makes pottery
Porcelain fever tablet the 5, first battery lead plate the 2, second battery lead plate the 4, the 3rd battery lead plate 6 insulating barrier 1 forms.Second
Battery lead plate 4 is clamped by first ceramic heating plate the 3, second ceramic heating plate 5, the first ceramic heating plate 3,
The opposite side of two ceramic heating plates 5 is close to clamp by the first battery lead plate 2 and the 3rd battery lead plate 6 respectively, and first
Insulating barrier 1 is had to be separated by between battery lead plate 2 and the outside of the 3rd battery lead plate 6 and aluminum radiating piece 201.First electricity
Pole plate the 2, the 3rd battery lead plate 6 is connected with zero line, and the second battery lead plate 4 is connected with live wire.So aluminum radiating piece
The first battery lead plate 2 and the 3rd battery lead plate 6 that 201 shells are relative are all connecting to neutral lines, electromotive force approximation ground potential,
Reduce electric potential difference, thus eliminate faradism.
After using above-mentioned structure, the battery lead plate of line of starting to exchange fire with two ceramic heating plate clampings, two potteries are sent out
The battery lead plate of another survey connecting to neutral line of backing is close to, and has absolutely between connecting to neutral line electrode plate and aluminum radiating piece 201
Edge layer 1 is separated by, and such structure makes the electrode corresponding with aluminum radiating piece 201 shell be all close to ground potential
Zero line, reduce electric potential difference between the two, thus eliminate the faradism of aluminothermy part.This structure has used two
Sheet ceramic heating plate, and without excess metal screen layer, firing rate improves, and heat conductivity increases, manufacturing process
Simply.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by upper
State the restriction of mode, if the various unsubstantialities that the method design that have employed the present invention is carried out with technical scheme
Improvement, or the most improved design by the present invention and technical scheme directly apply to other occasion, all exists
Within protection scope of the present invention.
