Abstract
The invention relates to a novel heater of an icing detector. The heater is composed of a heating section (1), an insulation layer (2), a housing (3) and a cooling end (4). The heating section (1) is in serial connection to the cooling end (4), and is separated from the housing (3) through the insulation layer (2), which can guarantee insulation resistance and anti-electric strength of the heater. According to the invention, the heater has simple structure and theory which is easy to understand, can better realize sectional heating after the introduction of the cooling end, avoids extra loss of electric power upon heating, and at the same time can effectively increase working stability and service life of the heater.
Description
Technical field
The invention belongs to heater design field, relate to a kind of novel icing detector heater.
Background technology
Heater technology uses field quite varied and important, especially in aircraft icing detection field
In.Icing detector probe needs deicing when freezing to continue icing detection, and heater is to remove
The key of ice, heater is the part needing heating with the position of probe contacts, and other parts are outstanding
Dummy status need not heating, and existing heater is owing to persistently heating frequently, it is not necessary to heating
Partially due to radiating condition is poor, during heating, temperature is the highest, strong influence use longevity of heater
Order and be lost the electric energy of aircraft.
Summary of the invention
It is an object of the invention to: provide one can realize zone heating, hot cold shut from, not only may be used
To improve the service life of heater, unnecessary electric energy loss can also be reduced.
The technical scheme is that the heater of a kind of novel ice detector, including bringing-up section 1,
Insulating barrier 2, shell 3 and cold end 4, bringing-up section 1 is connected in series with cold end 4, and by insulating barrier 2
Keeping apart with shell 3, bringing-up section 1 is high resistivity material, and cold end 4 is low resistivity material,
And ring set is on bringing-up section 1 surface, it is welded and fixed in the one end near bringing-up section 1, cold end 4 resistance
Rate is less than 1:5 with the ratio of bringing-up section 1 resistivity.
Further, above-mentioned bringing-up section 1 material is Cr20Ni80.
Further, above-mentioned bringing-up section 2 material is pure nickel.
Because bringing-up section 1 and the cold end 4 of heater are connected in series, energising time, heating power P with
Resistance value R is directly proportional.Bringing-up section 1 is high resistivity material through whole heater length scope,
Cold end 4 be low resistivity material ring set on bringing-up section 1 surface, and near the one of bringing-up section 1
End welding, cold end 4 is distributed in heater and need not the region of heating.
The present invention has the advantage that and provides the benefit that: can realize segmentation add by arranging cold end
Cold shut hot, hot from, be possible not only to improve heater service life, unnecessary electricity can also be reduced
Can loss.
Accompanying drawing explanation
Fig. 1 is the structure chart of this novel ice detector heater；
Wherein: 1. bringing-up section, 2. insulating barrier, 3. shell, the coldest end.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in further details.
A kind of heater of novel ice detector, including bringing-up section 1, insulating barrier 2, shell 3 and
Cold end 4, bringing-up section 1 is connected in series with cold end 4, and is kept apart with shell 3 by insulating barrier 2,
Ensureing insulation resistance and the dielectric strength of heater, bringing-up section 1 is high resistivity material, cold end 4
For low resistivity material, and ring set is on bringing-up section 1 surface, near one end of bringing-up section 1 welding
Fixing, cold end 4 electricalresistivityρ2With bringing-up section 1 electricalresistivityρ1Relation is ρ2＜ 0.2 ρ1。
Because bringing-up section 1 and the cold end 4 of heater are connected in series, energising time, heating power P with
Resistance value R is directly proportional.Such as heater structure in accompanying drawing, bringing-up section 1 is high resistivity material, can
To select Cr20Ni80 etc., and through whole heater length scope, cold end 4 is low-resistivity material
Material, can select pure nickel etc., and ring set is on bringing-up section 1 surface, and near the one of bringing-up section 1
End welding.
Cold end 4 is distributed in heater and need not the region of heating, in the situation using 28VDC heating
Under, normal temperature condition issues the temperature at hot arc 1 and is about 120 DEG C, and cold junction temperature is about 30 DEG C, this
Sample achieves zone heating, low in the local temperature that need not heating, needs heating interval temperature high,
And decrease electricity loss, and improve the service life of heater.
