The PTC heater (203) comprises a first electrode plate (2), a second electrode plate (4), a third electrode plate (6), a first ceramic heating plate (3), a second ceramic heating plate (5) and an insulating layer (1); two ceramic heating plates are utilized, residual metal shielding layers are omitted, the heating speed is high, the heat conduction performance is improved, and the manufacture process is simple.
Description
Technical field
The invention belongs to PTC heater technical field, particularly relate to the faradic PTC heater device of a kind of elimination.
Background technology
Present stage, all ptc heaters all can produce induced electricity, and prior art mainly eliminates induced electricity by adding metal screen layer.Its method is that screen is connected with zero line, has insulating barrier to be separated by between screen and aluminium heat-delivery surface, makes screen electromotive force be approximately zero, thus eliminates the induced electricity on aluminium heat sink surface in heater external rings around a circle metal screen layer.
Realizing in process of the present invention, inventor finds that prior art at least exists following problem: but prior art is when making the metal screen layer of parcel heater, and poor thermal conductivity, failure rate is high, and manufacturability is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of firing rate and improves, and thermal conductivity increases, and manufacturing process simply eliminates faradic PTC heater device.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: the faradic PTC heater device of a kind of elimination, comprise PTC heater, described PTC heater comprises the first battery lead plate, the second battery lead plate, the first ceramic heating plate and insulating barrier, also comprise third electrode plate and the second ceramic heating plate, described first battery lead plate is connected with zero line with third electrode plate, and described second battery lead plate is connected with live wire.
Comprise aluminium heat sink, described aluminium heat sink is hollow structure, is inside provided with heat radiation inner chamber, is provided with PTC heater in heat radiation inner chamber.
Described second battery lead plate both sides are the first ceramic heating plate and the second ceramic heating plate, are the first battery lead plate outside described first ceramic heating plate, are third electrode plate outside described second ceramic heating plate,
Coated insulation layer outside described first battery lead plate and third electrode plate.
Described first battery lead plate, third electrode plate are connected with zero line, and 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 tool in technique scheme has the following advantages or beneficial effect, the battery lead plate of line of starting to exchange fire is clamped with two ceramic heating plates, the battery lead plate of another survey connecting to neutral line of two ceramic heating plates is close to, insulating barrier is had to be separated by between connecting to neutral line electrode plate and aluminium heat sink, such structure makes the electrode corresponding with aluminium heat sink shell be all zero line close to ground potential, reduce electrical potential difference between the two, thus eliminate the induced electricity of aluminothermy part.This structure two panels ceramic heating plate, and without excess metal screen, firing rate improves, thermal conductivity increases, and manufacturing process is simple.
Accompanying drawing explanation

Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
See Fig. 1, the faradic PTC heater device of a kind of elimination, comprise aluminium heat sink 201, aluminium heat sink is hollow structure, inside be provided with heat radiation inner chamber 202, PTC heater 203 is provided with in heat radiation inner chamber 202, PTC heater 203 comprises the first battery lead plate 2, second battery lead plate 4, third electrode plate 6, first ceramic heating plate 3, second ceramic heating plate 5 and insulating barrier 1, second battery lead plate 4 both sides are the first ceramic heating plate 3 and the second ceramic heating plate 5, it is the first battery lead plate 2 outside first ceramic heating plate 3, be third electrode plate 6 outside second ceramic heating plate 5
As shown in Figure 2, coated insulation layer 1 outside the first battery lead plate 2 and third electrode plate 6;
First battery lead plate 2, third electrode plate 6 are connected with zero line, and the second battery lead plate 4 is connected with live wire.
Fig. 2 is the cutaway view of PTC heater, and PTC heater comprises the first ceramic heating plate 3, second ceramic heating plate 5, first battery lead plate 2, second battery lead plate 4, third electrode plate 6 insulating barrier 1 forms.Second battery lead plate 4 is clamped by the first ceramic heating plate 3, second ceramic heating plate 5, the opposite side of the first ceramic heating plate 3, second ceramic heating plate 5 is close to by the first battery lead plate 2 and third electrode plate 6 respectively and is clamped, and has insulating barrier 1 to be separated by between the outside of the first battery lead plate 2 and third electrode plate 6 and aluminium heat sink 201.First battery lead plate 2, third electrode plate 6 are connected with zero line, and the second battery lead plate 4 is connected with live wire.The first battery lead plate 2 that such aluminium heat sink 201 shell is relative and third electrode plate 6 are all connecting to neutral lines, and electromotive force is similar to ground potential, reduce electrical potential difference, thus eliminate induced electricity.
After adopting above-mentioned structure, the battery lead plate of line of starting to exchange fire is clamped with two ceramic heating plates, the battery lead plate of another survey connecting to neutral line of two ceramic heating plates is close to, insulating barrier 1 is had to be separated by between connecting to neutral line electrode plate and aluminium heat sink 201, such structure makes the electrode corresponding with aluminium heat sink 201 shell be all zero line close to ground potential, reduce electrical potential difference between the two, thus eliminate the induced electricity of aluminothermy part.This structure two panels ceramic heating plate, and without excess metal screen, firing rate improves, thermal conductivity increases, and manufacturing process is simple.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
