Description
Technical field
The utility model is related to thick film heating Manifold technology field, more particularly to a kind of anti-Local Dry sintering of thick film heating pipe
Structure.
Background technology
Used as a kind of new-type heating mode of heating, thick film heating technique is just little by little applied to electrical heating miscellaneous
In device.For thick film heating body, it is to be powered to producing heat by thick-film resistor paste, and then realizes heating function.
Thick film heating technique is quick because of it, efficiently, is used more and more extensively in actual life, and exist in the prior art
The thick film water heater being in various forms, such as thick film heating pipe etc..
It should further be noted that for thick film heating pipe, because of the difference of production process, there is local temperature in thick film heating pipe
The higher phenomenon of degree（As local dry burning）, this life-span that can directly affect heat-generating pipe and security；However, prior art is difficult
Detection such case, particularly user when in use, can not just detect at all.
Utility model content
The purpose of this utility model is in view of the shortcomings of the prior art and provides a kind of anti-local dry burning of thick film heating pipe
Structure, the anti-local dry burning structure of the thick film heating pipe can quickly and easily detect that thick film heating pipe whether there is local dry burning
Problem, is on the one hand conducive to conveniently choosing defective work in production, on the other hand can in time break when there is local dry burning
Electricity, to ensure security when using.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions.
A kind of anti-local dry burning structure of thick film heating pipe, includes in the metal base body of hollow circular tube shape, metal
The outer circumference surface of base material body is provided with the insulating barrier that resistance value is varied with temperature, and the outer circumference surface of insulating barrier is provided with by thick film
The heater of resistance slurry printing；
The anti-local dry burning structure of the thick film heating pipe also includes controller, controller respectively with metal base body, hair
Hot body electrical connection.
Wherein, the metal base body is stainless steel body.
Wherein, the metal base body is aluminium alloy body.
The beneficial effects of the utility model are：The anti-local dry burning structure of a kind of thick film heating pipe described in the utility model,
Its metal base body outer circumference surface is provided with the insulating barrier that resistance value is varied with temperature, and insulating barrier outer circumference surface is provided with by thickness
The heater of film resistance slurry printing；The anti-local dry burning structure of the thick film heating pipe also includes controller, controller difference
Electrically connected with metal base body, heater.The anti-local dry burning structure of the thick film heating pipe can quickly and easily detect thickness
Film heat-generating pipe whether there is local dry burning problem, on the one hand be conducive to conveniently choosing defective work, another aspect energy in production
It is enough to be powered off in time when there is local dry burning, to ensure security when using.
Brief description of the drawings
The utility model is further detailed below with accompanying drawing, but the embodiment in accompanying drawing do not constitute it is right
Any limitation of the present utility model.
Fig. 1 is structural representation of the present utility model.
Include in Fig. 1：
1 --- metal base body
2 --- insulating barrier
3 --- heater
4 --- controller.
Specific embodiment
The utility model is illustrated with reference to specific embodiment.
As shown in figure 1, a kind of anti-local dry burning structure of thick film heating pipe, includes the metal base in hollow circular tube shape
Body 1, the outer circumference surface of metal base body 1 is provided with the insulating barrier 2 that resistance value is varied with temperature, the excircle of insulating barrier 2
Face is provided with the heater 3 printed by thick-film resistor paste.
Further, the anti-local dry burning structure of the thick film heating pipe also includes controller 4, controller 4 respectively with metal
Base material body 1, heater 3 are electrically connected.
Wherein, metal base body 1 of the present utility model can be prepared from using stainless steel or aluminum alloy materials, i.e.,
Metal base body 1 is stainless steel body or aluminium alloy body；Certainly, above-mentioned metal material is not constituted to the utility model
Limitation, i.e., metal base body 1 of the present utility model can also be prepared from using other metal materials, such as copper material
Deng.
During utility model works, the utility model connects heater 3, metal base body by controller 4
1, controller 4 first gather insulating barrier 2 by electric current, the current signal that then controller 4 pairs is gathered carries out Treatment Analysis simultaneously
The temperature of insulating barrier 2 is judged, when the current value by insulating barrier 2 is less than 0.5 MAH, then it represents that the temperature of insulating barrier 2 is less than
250 degree；When the current value by insulating barrier 2 close to 5 MAHs, then it represents that the temperature value of insulating barrier 2 is 250 degree of -300 degree；When
10 MAHs are more than by the current value of insulating barrier 2, then it represents that the temperature value of insulating barrier 2 is more than 350 degree；Wherein, when insulating barrier 2
Temperature when being more than 300 degree, controller 4 stops powering for heater 3, and heater 3 is stopped.
Summary situation understands that, by said structure design, the utility model can quickly and easily detect thick film
Heat-generating pipe whether there is local dry burning problem, on the one hand be conducive to conveniently choosing defective work in production, on the other hand can
Powered off in time when there is local dry burning, to ensure security when using.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, will change in specific embodiments and applications, this specification content should not be construed as
To limitation of the present utility model.
