Abstract
The utility model relates to a PTC heater comprising a PTC heating assembly and heat radiation assemblies bonded to the outer surface of the PTC heating assembly. The PTC heating assembly includes an aluminium tube, a PTC heating sheet arranged inside the aluminium tube, and a piece of insulation paper covering the PTC heating sheet. Besides, a glue line or glue lines is/are coated on one surface or two surfaces of the insulation paper; and the surface or surfaces with the glue of the insulation paper is/are contacted with the inner wall of the aluminium tube. Disclosed in the utility model is the PTC heater. Because of the low friction coefficient of the surface or surfaces with the glue of the insulation paper, when the heater is electrified, no friction is caused between the insulation paper and the aluminium tube due to the extension of the aluminium tube, thereby eliminating the abnormal sound generated by the electrification of the heater.
Description
Technical field
The utility model relates to a kind of electric heater, is specifically related to a kind of ptc heater for the air-conditioning auxiliary heating.
Background technology
The PTC heating element that uses on the market is widely used in the civilian electric heating equipment.Along with growth in the living standard, the consumer also constantly improves the requirement of electric heating equipment, such as more attractive in appearance, more efficient, safer, requires also more and more higher to the muting function of electric heating equipment simultaneously.In the PTC heating element of existing extensive use, the insulating paper of parcel PTC sheet and electrode slice all is the light film, and when heater was switched on, aluminum pipe was inner because the effect of expanding with heat and contract with cold can produce abnormal sound with the insulating paper friction.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of PTC heating element, the Abnormal Sound that produces in the time of can eliminating the heater energising.
For achieving the above object, the technical solution of the utility model is as follows: a kind of ptc heater, comprise PTC heat generating component and the radiating subassembly that is adhered to described PTC heat generating component outer surface, described PTC heat generating component comprises aluminum pipe, be arranged at the PTC fever tablet of described aluminum pipe inside and coat the insulating paper of described PTC fever tablet, the one or both sides of described insulating paper are coated with glue-line, and the surface with glue of described insulating paper contacts with the aluminum pipe inwall.
Preferably, described glue-line is poly-perfluoro second propylene glue-line.
Preferably, described aluminum pipe is flat tube.
Preferably, described radiating subassembly comprises top board, base plate and is connected the aluminium ripple that is connected with described top board lead welding with described base plate, and described base plate and described aluminum pipe are bonding, and described top board is provided with window.
Preferably, described top board and described base plate are aluminium sheet.
Preferably, described window is that triangle or rectangle are square or circular.
Preferably, the quantity of described window is at least one.
Adopt the beneficial effect of above technical scheme to be: because the coefficient of friction of insulating paper surface with glue is less, during the heater energising, insulating paper just not can and aluminum pipe between because the extension of aluminum pipe produces very large friction, the Abnormal Sound that has produced when having eliminated the heater energising.

Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of ptc heater, comprise PTC heat generating component and the radiating subassembly that is adhered to described PTC heat generating component outer surface, described PTC heat generating component comprises aluminum pipe, be arranged at the PTC fever tablet of described aluminum pipe inside and coat the insulating paper of described PTC fever tablet, the one or both sides of described insulating paper are coated with glue-line, and the surface with glue of described insulating paper contacts with the aluminum pipe inwall.
Embodiment 1:
As shown in Figure 1, PTC heater is comprised of PTC heat generating component 11 and the radiating subassembly 12 that is fixed in PTC heat generating component both sides, and PTC heat generating component 11 and radiating subassembly 12 usefulness silica gel are bonding.As shown in Figure 2, PTC heat generating component 11 comprises aluminum pipe 1, insulating paper 3, PTC fever tablet 5 and electrode slice 4, electrode slice 4 usefulness silica gel are adhered to upper surface and the lower surface of PTC fever tablet 5, be positioned in the aluminum pipe 1 behind the PTC fever tablet 5 that insulating paper 3 coatings are bonded as one and the electrode slice 4, aluminum pipe 1 is flat tube.As shown in Figure 3, a face of insulating paper 3 is coated with a strata perfluoro second propylene glue-line 2, and after insulating paper 3 coated PTC fever tablet 5 and electrode slice 4, the surface with glue of insulating paper 3 contacted with the inner surface of aluminum pipe 1.Radiating subassembly 12 is the frame structures that formed by aluminium ripple, top board 6 and base plate 7 lead weldings, and wherein top board 6 and base plate 7 are aluminium sheet, and base plate 7 is bonded on the outer surface of aluminum pipe 1 by silica gel.As shown in Figure 4, also offer a plurality of windows 8 on the top board, window 8 be shaped as the U-shaped window.
Behind the poly-perfluoro second propylene glue-line of the surface-coated of insulating paper, coefficient of friction can reduce greatly, ptc heater adopts the insulating paper of surface band glue, after coating PTC fever tablet and electrode slice, surface with glue contacts with the aluminum pipe inwall, because the surface with glue coefficient of friction is little, and is little with aluminum pipe inwall contact resistance, the Abnormal Sound in the time of can avoiding switching on.
Ptc heater adopts insulating paper to coat the structure of PTC fever tablet and electrode slice, and the aluminum tube surfaces of PTC heat generating component is not charged, has improved the fail safe of ptc heater.
The PTC heater is because its special resistance-temperature characteristic, must be with dispelling the heat, radiating subassembly is formed by aluminium ripple and aluminium flake lead welding, the wing of aluminium ripple is apart from very little, during work, air-conditioning fan blows the PTC heater, and less wing so that windage strengthens, occurs howling apart from meeting through radiating subassembly the time.Ptc heater of the present utility model is opened window or the hole of certain area at the top board of radiating subassembly, so that wind has reduced windage when blowing over heater, just howling can not occur in actual the use.
