Abstract
The invention discloses a heating device eliminating induced electricity. The device comprises an aluminum radiating member (201) in a hollow structure; the aluminum radiating member (201) is provided with a radiating cavity (202) inside; the radiating cavity (202) is provided with a PTC heater (203) inside. The PTC heater (203) comprises a ceramic heating sheet (4), a first electrode plate (3), a second electrode plate (2) and an insulating layer (1); the electrode plates connected to the zero line serve as shielding layers directly, the number of heat insulation layers is reduced, 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 electro-heat equipment 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 that a kind of thermal conductivity improves, and manufacturing process simply eliminates faradic PTC electro-heat equipment.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: the faradic PTC electro-heat equipment of a kind of elimination, comprise PTC heater, described PTC heater comprises ceramic heating plate, the first battery lead plate, the second battery lead plate and insulating barrier, described first battery lead plate is connected with live wire, and described second battery lead plate is connected with zero line.
Comprise aluminium heat sink, described aluminium heat sink is hollow structure, is inside provided with heat radiation inner chamber, in heat radiation inner chamber
Be provided with PTC heater.
Described second battery lead plate is trench structure, and described fever tablet stretches in the groove of the second battery lead plate;
In the groove that described first battery lead plate stretches into the second battery lead plate and between the second battery lead plate and fever tablet;
In the groove that the second battery lead plate is stretched in described insulating barrier one end and between the first battery lead plate and the second battery lead plate, the other end is wound around and covers the outside of the second battery lead plate.
Described first battery lead plate is connected with live wire; Described second battery lead plate is connected with zero line.
Described first battery lead plate is provided with draw-in groove, and one end of described insulating barrier snaps in described draw-in groove.
A technical scheme tool in technique scheme has the following advantages or beneficial effect, using the battery lead plate of connecting to neutral line directly as screen, which reduces the heat insulation number of plies, and thermal conductivity improves, and manufacturing process is simple.
Accompanying drawing explanation
The structural representation of elimination faradic PTC electro-heat equipment of Fig. 1 for providing in the embodiment of the present invention;
Fig. 2 is the structural representation of the PTC heater of Fig. 1;
Mark in above-mentioned figure is: 1, insulating barrier, the 2, second battery lead plate, the 3, first battery lead plate, and 4, ceramic heating plate, 201, aluminium heat sink, 202, heat radiation inner chamber, 203, 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 electro-heat equipment of a kind of elimination, comprise aluminium heat sink 201, aluminium heat sink 201 is hollow structure, inside be provided with heat radiation inner chamber 202, be provided with PTC heater 203, PTC heater 203 in heat radiation inner chamber 202 and comprise ceramic heating plate 4, first battery lead plate 3, second battery lead plate 2 and insulating barrier 1, second battery lead plate 2 is trench structure, and ceramic heating plate 4 stretches in the groove of the second battery lead plate 2;
As shown in Figure 2, the first battery lead plate 3 stretch into the second battery lead plate 2 groove in and between the second battery lead plate 2 and ceramic heating plate 4;
In the groove that the second battery lead plate 2 is stretched in insulating barrier 1 one end and between the first battery lead plate 3 and the second battery lead plate 2, the other end is wound around and covers the outside of the second battery lead plate 2; First battery lead plate 3 is provided with draw-in groove, and one end of insulating barrier 1 snaps in draw-in groove.
First battery lead plate 3 is connected with live wire; Second battery lead plate 2 is connected with zero line.
Ceramic heating plate 4 is close to by the first battery lead plate 3 and the second battery lead plate 2 and is clamped, and first battery lead plate 3 one end kills insulating barrier 1; Second battery lead plate 2 is while be close to ceramic heating plate 4, and another side wraps up the first battery lead plate 3.Insulating barrier 1 is all had to be separated by between first battery lead plate 3, second battery lead plate 2, aluminium heat sink 201.First battery lead plate 3 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 zero line, and parcel the first electrode slice, between have insulating barrier 1 to be separated by, therefore have electromotive force to be approximately equal to ground potential between the first battery lead plate 3 of high potential and aluminium heat sink 201 and be separated by, aluminium heat sink 201 induced electricity can be eliminated.
After adopting above-mentioned structure, using the battery lead plate of connecting to neutral line directly as screen, which reduce the heat insulation number of plies, thermal conductivity improves, and manufacturing process is simple.Reduce failure rate, convenient operation, be easy to manufacture.
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.
