Abstract
The utility model discloses the faradic PTC heater device of a kind of elimination, comprise aluminium heat sink (1), aluminium heat sink (1) is hollow structure, inside be provided with heat radiation inner chamber (9), PTC heater (201) is provided with in heat radiation inner chamber (9), PTC heater comprises ceramic heating plate (6), first battery lead plate (5), second battery lead plate (7), first screen (2), secondary shielding layer (8), first insulating barrier (4) and the second insulating barrier (3), effectively eliminate induced electricity, because screen is not all wrap heater, both sides still can high efficiency and heat radiation, improve the efficiency of heating surface.
Description
Technical field
The utility model belongs to PTC heater technical field, particularly relates 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 encloses metal screen layer in heater external rings around one, separates between metal screen layer with heater and between heat radiation aluminum component with insulating material,
Realizing in process of the present utility model, inventor finds that prior art at least exists following problem: its structure and manufacturing process complexity, because screen wraps heater completely, can make thermal conductivity be deteriorated like this, reduce the efficiency of heating surface.
Summary of the invention
Technical problem to be solved in the utility model is to provide one can high efficiency and heat radiation, improves the faradic PTC heater device of elimination of the efficiency of heating surface.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: the faradic PTC heater device of a kind of elimination, comprise aluminium heat sink, described aluminium heat sink is hollow structure, inside be provided with heat radiation inner chamber, be provided with PTC heater in heat radiation inner chamber, described PTC heater comprises ceramic heating plate, the first battery lead plate, the second battery lead plate, the first screen, secondary shielding layer, the first insulating barrier and the second insulating barrier
Ceramic heating plate both sides are clamped by the first battery lead plate and the second battery lead plate, and wrapped up by the first insulating barrier outside the first battery lead plate and the second battery lead plate, the first screen and secondary shielding layer are positioned at fever tablet both sides and are close to outside the first insulating barrier; Wrapped up by the second insulating barrier outside first screen and secondary shielding layer;
Described first battery lead plate is connected with civil power live wire with the second battery lead plate, and described first screen is connected with zero line with secondary shielding layer.
A technical scheme tool in technique scheme has the following advantages or beneficial effect, and manufacturing process is simple, reduces cost, effectively eliminates induced electricity, and because screen is not all wrap heater, both sides still can high efficiency and heat radiation, improves the efficiency of heating surface.
Accompanying drawing explanation
The structural representation of elimination faradic PTC heater device of Fig. 1 for providing in the utility model embodiment;
Fig. 2 is the structural representation of the screen of Fig. 1;
Mark in above-mentioned figure is: 1, aluminium heat sink, the 2, first screen, the 3, second insulating barrier, the 4, first insulating barrier, the 5, first battery lead plate, and 6, ceramic heating plate, the 7, second battery lead plate, 8, secondary shielding layer, 9, inner chamber, 201, PTC heater.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
See Fig. 1, the faradic PTC heater device of a kind of elimination, comprise aluminium heat sink 1, aluminium heat sink 1 is hollow structure, inside be provided with heat radiation inner chamber 9, be provided with PTC heater 201, PTC heater in heat radiation inner chamber 9 and comprise ceramic heating plate 6, first battery lead plate 5, second battery lead plate 7, first screen 2, secondary shielding layer 8, first insulating barrier 4 and the second insulating barrier 3
As shown in Figure 2, ceramic heating plate 6 both sides are clamped by the first battery lead plate 5 and the second battery lead plate 7, wrapped up by the first insulating barrier 4 outside first battery lead plate 5 and the second battery lead plate 7, the first screen 2 and secondary shielding layer 8 are positioned at ceramic heating plate 6 both sides and are close to outside the first insulating barrier 4; Wrapped up by the second insulating barrier 3 outside first screen 2 and secondary shielding layer 8;
First battery lead plate 5 is connected with civil power live wire with the second battery lead plate 7, and the first screen 2 is connected with zero line with secondary shielding layer 8.
First screen 2 and secondary shielding layer 8 material are aluminium foil, copper sheet or other refractory metal thin slice.
Owing to there being the screen of nearly zero line electromotive force to shield between the battery lead plate and aluminium heat sink 1 of high potential, thus make aluminium heat sink 1 surface potential be approximately equal to ground potential, can induced electricity be eliminated.
After adopting above-mentioned structure, manufacturing process is simple, reduces cost, effectively eliminates induced electricity, and because screen is not all wrap heater, both sides still can high efficiency and heat radiation, improves the efficiency of heating surface.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection range of the present utility model without to improve.
