Description
Technical field
The utility model relates to electricity field more particularly to ptc heater, especially a kind of aluminium pipe type high voltage P TC adds
Hot device.
Background technique
Traditional ptc heater is using cuboid PTC ceramic element as heater element.In the electrode of PTC ceramic element
Then upper covering power-on and power-off pole piece wraps up insulating materials or covering alumina ceramic substrate, compresses after filling in aluminum pipe.Finally in aluminium
Heat sink strip (or wearing fin on aluminum pipe) is bonded on pipe, distributes heat.This traditional structure, electrode is unilateral to radiate
Face.Electrode slice is located at the big plane of sheet PTC ceramic element or more.In order to be used under the high voltage of 300V or more, it is necessary to
The normal temperature resistance value of PTC ceramic element is improved, while needing to increase the thickness of PTC ceramic element, to bear higher voltage.One
As for, in use, the thickness of PTC ceramic element selects between 2~4mm under 300~900V voltage.But PTC ceramics
The increase of component thickness is not linearly increasing using voltage, this is because when the thickness of PTC ceramic element increases,
Heat among PTC ceramic element is just not easy to distribute, and leads to the raising of the center portion thereof position temperature, the raising of temperature, central part
Position resistance with regard to big, voltage centre partial pressure with regard to big, easily cause breakdown or the cracking of PTC ceramic element in this way.
So the thickness of PTC ceramic element is not more thicker better.
Due to this limitation of PTC ceramic element, in actual use, the short circuit of PTC ceramic element often occurs
Breakdown, while the use voltage of PTC ceramic element can not be made again high.
Utility model content
In view of the above technical problems, the purpose of this utility model is to provide a kind of PTC for solving above-mentioned technical problem to add
Hot device.
In order to solve the above technical problems, aluminium pipe type high voltage P TC heater provided by the utility model, comprising: PTC ceramics
Element, the PTC ceramic element is in cuboid, including a top surface, a bottom surface, two long side surfaces being parallel to each other and two
The short sides being parallel to each other, the area of top and bottom are respectively greater than any one long side surface or the face of any one short sides
Product；Electrode slice, the quantity of the electrode slice are two, and two electrode slices are respectively overlay in the length of the PTC ceramic element
On side；Insulating paper, the insulating paper are wrapped on the outside of the PTC ceramic element and the electrode slice；Aluminum pipe, the aluminium pipe sleeve
It is located on the outside of the insulating paper, after the aluminum pipe pressure pipe, the side wall of the aluminum pipe is inwardly recessed the side wall so that the aluminum pipe
The insulating paper, the electrode slice and the PTC ceramic element are in close contact.
Spacing between two electrode slices is 3 millimeters~30 millimeters.
The width of the electrode slice is 1 millimeter~5 millimeters.
The length of the electrode slice is 5 millimeters~50 millimeters.
The aluminium pipe type high voltage P TC heater of the utility model is in PTC ceramic element, using the design of side electrode,
Flow into electric current by side electrode, perpendicular to side electrode two big planes as radiating surface.This design, due to adopting
With side electrode, interelectrode thickness is increased, and pressure resistance can obtain very big raising, and PTC ceramic element centre
Heat be sufficiently radiated under the heat dissipation of two side radiators, will not because of PTC ceramic element thickness increase and cause to puncture.
So the design of this PTC ceramic element side electrode, can increase substantially PTC by increasing the thickness between electrode slice
Ceramic component uses voltage.Allow ptc heater to work to use under the even higher voltage of 900 ~ 1500V.
Detailed description of the invention

Fig. 2 is the planar structure schematic diagram of the aluminium pipe type high voltage P TC heater of the utility model;
Fig. 3 is the 3D structural schematic diagram of the aluminium pipe type high voltage P TC heater of the utility model.
Specific embodiment
The ptc heater of the utility model is described in further detail with reference to the accompanying drawing.
The side electrode of PTC ceramic element, i.e. thickness between power-on and power-off pole-face are greater than the width of electrode, in practical application
In, it is not the same face that electrode surface and radiating surface, which are vertical,.Then radiating surface is utilized, installation radiator realizes heat dissipation.Using
Side electrode increases interelectrode thickness, while ensuring the heat dissipation at position among PTC ceramics, and PTC can be greatly improved
The pressure resistance of heater, it is therefore prevented that short circuit breakdown.
As shown in Figure 2 to 3, aluminium pipe type high voltage P TC heater provided by the utility model, by PTC ceramic element 1,
It is interior after the lower planes of aluminum pipe 4 are compacted after electrode slice 2, insulating paper 3 etc. fill in side equipped with the aluminum pipe 4 of concave inward structure 5
Recessed structure 5 can further be recessed inwardly, and compress electrode slice 2, insulating paper 3 and PTC ceramic element 1 closely, and realization is reliably led
Conductance hot property.Then, it is bonded radiator (or putting on fin on aluminum pipe 4) on 4 surface of aluminum pipe, realizes heat dissipation.
Using the PTC ceramic element 1 of side electrode slice 2, the voltage that uses of ptc heater can be increased substantially, significantly
The pressure-resistant reliability for improving heater, the generation for avoiding short circuit from puncturing.
The originally heat of the PTC ceramic element 1 of structure needs to be transmitted to again by electrode slice 2, insulating paper 3, aluminum pipe 4
On radiator, after side electrode slice 2, the heat of PTC ceramic element 1, it is only necessary to be transmitted to by insulating paper 3, aluminum pipe 4 scattered
On hot device, thermal resistance is reduced, and the heat radiation power of heater can be promoted.
The preferred embodiment created to the utility model above is illustrated, but the utility model is created not
It is limited to embodiment, those skilled in the art can also make various under the premise of without prejudice to the utility model creative spirit
