Abstract

The utility model discloses a PTC heater which comprises a heating conducting pipe and a PTC heating plate arranged in the heat conducting pipe. An elastic pad is arranged between the inner wall of heat conducting pipe and the PTC heating plate. Since the elastic pad has elasticity, the elastic pad can be fully combined with a PTC heating plate electrode, the contact resistance is small, so while the PTC heater has a heating function of a common PTC heater, a problem of electrode spark burning can be overcome, thus the security of the PTC heater is improved, and the service life of the PTC heater is prolonged.

Description

PTC heater
Technical field
The utility model belongs to the electric heater unit field, particularly a kind of PTC heater.
Background technology
The PTC heating technique has been widely used in the household electric appliances such as warm-air drier, air conditioner at present very much.Its principle of heating is that metal electrode (as copper electrode, aluminium electrode, stainless steel electrode etc.) is superimposed with the aluminum-spraying electrode of PTC fever tablet, and with being placed in aluminum pipe after polyimide laminated film parcel.This metal electrode draws that aluminum pipe is outer makes the heating of PTC fever tablet by energising, thereby and by being arranged on fin on aluminum pipe, carrying out the heat transmission and reach the heating purpose.Because contacting between the aluminum-spraying electrode of metal electrode and PTC fever tablet is that metal surface contacts firmly, its contact resistance is large, thus electrode easily sparking burn, affected safety and the useful life of PTC heater.
Therefore, need a kind of PTC heater, when possessing common PTC heater heating function, can overcome the problem that the electrode sparking is burnt, thereby improve the fail safe of PTC heater and extend its useful life.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of PTC heater, when possessing common PTC heater heating function, can overcome the problem that the electrode sparking is burnt, thereby improves the fail safe of PTC heater and extend its useful life.
For solving the problems of the technologies described above, PTC heater of the present utility model comprises the heat conduction pipe fitting and is arranged at the interior PTC fever tablet of heat conduction pipe fitting, it is characterized in that: between heat conduction pipe fitting inner wall and PTC fever tablet, cushion is set.
Further, described cushion is provided with metal forming with the surface that the PTC fever tablet contacts, and is electrically connected in the mode that directly contacts between this metal forming and PTC fever tablet.
Further, be electrically connected to described metal forming the electrode that is provided with for electric connection of power supply.
Further, described PTC fever tablet be set up in parallel on along its length in the heat conduction pipe fitting and the PTC fever tablet between potsherd is set.
Further, described heat conduction outer surface of pipe fittings is provided with fin.
Further, described heat conduction inside pipe fitting arranges fixed cover, on this fixed cover, hole is set, and described PTC fever tablet and potsherd are arranged in this hole.
Further, described heat conduction pipe fitting is aluminum pipe, and described aluminum pipe and fin are the integral type structure.
Further, the material of described cushion and fixed cover is the silica gel Compound Fabric, and described metal forming is aluminium foil.
Can learn by above technical scheme, the beneficial effects of the utility model are: PTC heater of the present utility model arranges cushion between heat conduction pipe fitting inner wall and PTC fever tablet, when possessing common PTC heater heating function, can overcome the problem that the electrode sparking is burnt, thereby improve the fail safe of PTC heater and extend its useful life.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Embodiment
Fig. 1 is the vertical section structure schematic diagram of the utility model embodiment, Fig. 2 is the cross section structure schematic diagram of the utility model embodiment A-A direction, as shown in the figure: the PTC heater of the present embodiment, its heat conduction pipe fitting 1 is aluminum pipe and with fin 2, is the integral type structure, and fin 2 is processed to form at the aluminum tube surfaces shovel by machining tool.This structure efficiently solve conventional P TC heating element adopt the bonding and bonding agent that bring of aluminum pipe and fin aging with the problem of peculiar smell is arranged, and improved heat exchange efficiency.The inner up and down of aluminum pipe tube wall is respectively placed a cushion 6, on these cushion 6 inwalls, metal forming 7 is set.This metal forming 7 is aluminium foil.Between two metal formings 7 in up and down along being set up in parallel PTC fever tablet 4 on the PTC heater length direction.This metal forming 7 directly with between PTC fever tablet 4 is electrically connected to by the mode that directly contacts.Simultaneously, be electrically connected to the electrode 3 that is provided with for electric connection of power supply with described metal forming, make PTC fever tablet heating power by metal forming after connecting power supply.Between each PTC fever tablet 4, potsherd 5 is set, can arrives the effect of filling insulant and strengthening PTC heater intensity.4 of potsherd 5 and PTC fever tablets can be gapped, but also gapless and directly the contact.Simultaneously,, for the position of fixing PTC fever tablet 4 with potsherd 5, also in heat conduction pipe fitting 1 inside, fixed cover 8 is set.The thickness of this fixed cover is identical with the thickness of PTC fever tablet 4, also can be less than its thickness.
Fig. 3 is the planar structure schematic diagram of the utility model embodiment cushion, and as shown in the figure: described cushion 6 is the silica gel Compound Fabric., because silica gel Compound Fabric surface has viscosity, therefore can be sidelong and put metal forming 7 at cushion 6 one.Because cushion 6 and metal forming 7 all have elasticity, so the electrode of PTC fever tablet 4 can fully fit with cushion 6 and metal forming 7, thereby contact resistance both is little, and electrode can not struck sparks and burn out, and has improved the fail safe of PTC heater and has extended its useful life.
Fig. 4 is the planar structure schematic diagram of the utility model embodiment fixed cover, and as shown in the figure: described fixed cover 8 is the silica gel Compound Fabric.The planar dimension of this fixed cover 8 is identical with cushion 6, and is provided with the hole 9 corresponding with PTC fever tablet 4, potsherd 5 positions and size thereon.During installation, fixed cover is positioned between two cushions 6, PTC fever tablet 4, potsherd 5 are placed in corresponding hole, thereby play the fixedly effect of PTC fever tablet 4, potsherd 5.
Cushion in above embodiment, fixed cover all adopt the silica gel Compound Fabric to be illustrated, and metal forming adopts aluminium foil to be illustrated.In fact, cushion, fixed cover are not limited to the silica gel Compound Fabric, can also be other materials that have elasticity and insulating properties is arranged.Metal forming also is not limited to aluminium foil, can also be the metal forming of other types, as Copper Foil etc.
Explanation is finally, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
