Description
Technical field
The invention belongs to PTC heater technical field, particularly relate to the faradic PTC heater 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: 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 thermal conductivity, manufacturing process is simple and reliable, and the height of failure rate is low eliminates faradic PTC heater.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: the faradic PTC heater of a kind of elimination, comprise aluminium heat sink, described aluminium heat sink is hollow structure, inside be provided with heat radiation inner chamber, described PTC heater is placed in heat radiation inner chamber, and described PTC heater comprises ceramic heating plate, the first battery lead plate, the second battery lead plate, the first insulating barrier, the second insulating barrier and screen, described first battery lead plate and the second battery lead plate are positioned at ceramic heating plate both sides
Described second battery lead plate is provided with clamping part, and described first insulating barrier and screen insert clamping part and wrap up the first battery lead plate and the second battery lead plate;
Be the first insulating barrier and screen successively outside second battery lead plate, the screen stretching into clamping part contacts with the second battery lead plate upper surface;
Described second insulating barrier wraps up described screen;
Described second battery lead plate is connected with zero line, and described first battery lead plate is connected with live wire.
Polymeric barrier layer materials is refractory metal thin slice.
A technical scheme tool in technique scheme has the following advantages or beneficial effect, screen and the first insulating barrier are pushed down in battery lead plate one end of connecting to neutral line, and then screen is wrapped up together with the first insulating barrier the battery lead plate of line of starting to exchange fire, which reduce the heat insulation number of plies, thermal conductivity improves; Battery lead plate kills screen and the such manufacturing process of the first insulating barrier is simple and reliable, failure rate is low, and can eliminate induced electricity.

Mark in above-mentioned figure is: 1, the first battery lead plate, the 2, second battery lead plate, the 3, first insulating barrier, and 4, screen, the 5, second insulating barrier, 8, ceramic heating plate, 201, aluminium heat sink, 202, inner chamber, 204, PTC heater.
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 of a kind of elimination, comprise aluminium heat sink 201, aluminium heat sink 201 is hollow structure, is provided with heat radiation inner chamber 202, is provided with PTC heater 204 in heat radiation inner chamber 202.
As shown in Figure 2, PTC heater 204 comprises ceramic heating plate 8, first battery lead plate 1, second battery lead plate 2, first insulating barrier 3, second insulating barrier 5 and screen 4, first battery lead plate 1 and the second battery lead plate 2 and is positioned at ceramic heating plate 8 both sides,
Second battery lead plate 2 is provided with clamping part, and the first insulating barrier 3 and screen 4 insert clamping part and wrap up the first battery lead plate 1 and the second battery lead plate 2;
Be the first insulating barrier 3 and screen 4 successively outside second battery lead plate 2, the screen 4 stretching into clamping part contacts with the second battery lead plate 2 upper surface;
Second insulating barrier 5 wraps up screen 4;
Second battery lead plate 2 is connected with zero line, and the first battery lead plate 1 is connected with live wire.
Ceramic heating plate 8 is close to by the first battery lead plate 1 and the second battery lead plate 2 and is clamped, the clamping part of second battery lead plate 2 one end kills screen 4 and the first insulating barrier 3, the upper surface of the second battery lead plate 2 contacts with screen 4, and then screen 4 and the first insulating barrier 3 remove parcel first battery lead plate 1.First battery lead plate 1 is connected with live wire, and the second battery lead plate 2 is connected with zero line.Because the second battery lead plate 2 is connected with screen 4, so the electromotive force of screen 4 and zero line equipotential, and between screen 4 and the second electrode slice, have the first insulating barrier 3 to be separated by, screen 4 and aluminium heat sink 201 have secondary shielding layer 4 to be separated by, make aluminium heat sink 201 surface potential be approximately equal to ground potential, can induced electricity be eliminated.
Screen 4 material is aluminium foil, copper sheet or other refractory metal thin slice.
Fig. 3 is the structural representation of the another kind of execution mode eliminating faradic PTC heater, for screen 4 and the first insulating barrier 3 wrap up the structure of the first battery lead plate 1 counterclockwise, is protected equally.
After adopting above-mentioned structure, battery lead plate one end of connecting to neutral line is pushed down screen 4 and the first insulating barrier 3, and then screen 4 is wrapped up the battery lead plate of line of starting to exchange fire together with the first insulating barrier 3, which reduce the heat insulation number of plies, thermal conductivity improves; Battery lead plate kills screen 4 and the such manufacturing process of the first insulating barrier 3 is simple and reliable, failure rate is low, and can eliminate induced electricity.
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.
