Plate 11 is fixed with cavity pedestal 13 by screw 10.
Further, 11 outer surface of heater cover board is coated with heat insulating coat 16, ensures unidirectional nonstorage calorifier
15 have the function of one-way heating.
The utility model has the beneficial effects that：The utility model is used for aviation surface pressure sensor by sense 14 pressure measurement of face
Hole position is heated, and has the characteristics that starting current is smaller, easy for assemble or unload, one-way heating, heating device is made to become one
A function module compensates for previous heating device dismounting inconvenience, causes by the defect that sense face 14 is scrapped and prevent interiors of products
The excessively high influence to component of temperature, simple in structure, maintainability is good, application easy to spread, has larger practical value.This reality
Aviation field is can be widely applied to novel, marketing has a extensive future.Specifically, haing the following advantages：
(1) the utility model uses single layer precision incense coil winding structure, heater fire end 9 to use square structure, have
Effect increases also contacts area, ensures to reach within 1.5 minutes entire heating surface heating, temperature controlling range is 180 DEG C~200 DEG C；
(2) the molding heater of incense coil coiling 12 is mounted in cavity pedestal 13 by the utility model, by heater
As Implement of Function Module Fast Installation, dismounting；
(3) heating module has fire end (rectangular protective case 7) and heat-insulated end (heater cover board 11 carries heat insulating coat 16),
Both reach anti-icing, deicing requirement, and can also meet the requirement of interiors of products element temperature in use.
