Abstract
A large-power tubular PTC heater belongs to the field of heating apparatus of air conditioner or heat radiator, comprising a heating unit, heat radiating strips and plugs arranged on both ends of the heating unit. The heating unit contains a heating inner core and aluminum tubes, wherein, the heating inner core consists of a central PTC sheet group, insulating rubber layers arranged on upper and lower surfaces of the PTC sheet group and electrode plates externally arranged on the insulating rubber layers. The utility model is characterized in that one or both surfaces of each electrode plate are respectively provided with an insulating ceramic sheet. The heating unit comprises the central PTC sheet group, the insulating rubber layers arranged on upper and lower surfaces of the PTC sheet group, the electrode plates externally arranged on the insulating rubber layers, the insulating ceramic sheet and the aluminum tubes, beside, the left and right sides at both front and back of the heating unit are provided with insulating interlayer. The utility model has the advantages of simple structure, good effect that the surface is uncharged, good heat radiating ability, large heating power, safe and reliable usage in addition to long service life.
Description
Technical field:
The utility model relates to a kind of full closed pipe type PTC heater, and it belongs to a kind of heater members that is mainly used on air-conditioning or the warm-air drier.
Background technology:
The insulation mode that existing High-Power PTC heating element is adopted mainly is to utilize insulation film, promptly at outer wrap one deck insulating paper of the heating inner core of heating element, to reach the heart of heating element and the insulation purpose between the aluminum pipe.But this insulating paper film so it is easy in use be damaged, causes punch-through owing to be flexible material.Under the situation that the insulation film parcel is arranged, the insulation film conductive coefficient is low, can have influence on the radiating effect of heating element in addition.
Technology contents:
The purpose of this utility model is to provide a kind of have good insulation performance and radiating effect, and is safe and reliable, the high-power tubular type PTC heater of long service life.
The purpose of this utility model is achieved in that
A kind of high-power tubular type PTC heater, it is made up of heater members, heat sink strip and the chock plug that is located at the heater members two ends, described heater members is made up of heating inner core and aluminum pipe, it is characterized in that being provided with insulating barrier at the one or both sides of the battery lead plate of described heating inner core; Be equipped with the insulation interlayer in the described both sides, all around that have the heating inner core of insulating barrier.Described insulating barrier is an insulating ceramic film.Described insulation interlayer is insulating ceramic film, electro-insulating rubber or mica.
The utility model is simple in structure, promptly has the not charged effect of surface of good, also has good heat-sinking capability, can realize powerful heating, and is safe and reliable, long service life.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is an internal structure schematic diagram of the present utility model
Accompanying drawing 3 is the A-A cutaway view of the utility model accompanying drawing 1
Accompanying drawing 4 is the vertical view of accompanying drawing 1 of the present utility model
Embodiment:
Be embodiment of the present utility model with accompanying drawing 1,2,3,4 below, the utility model be further detailed:
The utility model is by three most of compositions, and both heater members 1, heat sink strip 4,5 and be located at chock plug 2,3 compositions at heater members two ends; Heat sink strip 4,5 is located at respectively on two end faces up and down of heater members.Described heat sink strip 4,5 can use adhesive bonding or directly be welded in the groove of aluminum pipe 6 of heater members, and described aluminum pipe 6 is the external form of one flat " H " type, and heat sink strip 4,5 is under the situation of radiating fin, can directly be inserted in the groove of aluminum pipe 6.Described heat sink strip 4,5 can be the soldering bar, also can be the ripple bar, or radiating fin.Described heater members 1 is one group of structure that is superimposed, it is made up of heating inner core and insulating barrier 7,8, the heating inner core is located at the insulation glue-line 11,12 of PTC sheet group top and bottom by the PTC sheet group 13 that is positioned at the bosom, is located at insulation glue-line 11,12 outer battery lead plates 9,10 and forms; PTC sheet group 13, the insulation glue-line 11,12 that is located at PTC group sheet top and bottom and the battery lead plates 9,10 that are located at outside the insulation glue-line 11,12 all are wrapped in the aluminum pipe 6.In order to have good insulation performance between the heating inner core that guarantees aluminum pipe 6 and be wrapped, be provided with insulating barrier 7,8 on the one or both sides surface of battery lead plate 9,10.Described insulating barrier can be bonded in the surface of battery lead plate 9,10, makes between insulating barrier and the battery lead plate structure very close to each other, such help the heat radiation of heater members and avoids electricity sparking.In order to make insulating barrier 7,8 that certain durability be arranged, described insulating barrier 7,8 has adopted insulating ceramic film, has guaranteed the insulation effect of insulating barrier.Described insulation interlayer 14 is insulating ceramic film, electro-insulating rubber or mica.
