The invention belongs to the design fields of heater, and in particular to a kind of PTC ceramics heater.Common heater is fixed resistance heater, and heating rate is slow, generally temperature sensor is needed to control temperature.Heater life is low, and heating system is complicated, and reliability is low.PTC ceramics heater of the invention, be successively fixed on the inside of the cover board insulated thermal insulating layer, the conductive sheet on top, certain thickness PTC ceramics heating sheet and lower part conductive sheet, around the PTC ceramics heating sheet be coated with thermal plastic insulation.Heating rate is fast, and heating efficiency is high, long working life, high reliablity, and has self-regulated temperature characteristics, is suitble to promote in dual-use field, has biggish practical application value.
Description
Technical field
The invention belongs to the design fields of heater, and in particular to a kind of PTC ceramics heater.
Background technique
Low in the operating ambient temperature of aviation field, aircraft, there is the possibility to freeze in exposed equipment, influence its normal work
Make, heater need to be set and heated, is used for anti-icing and deicing.In addition, some devices cannot be normal under high-altitude low temperature environment
Work also needs setting to be heated, improves the operating ambient temperature around the device.
Common heater is fixed resistance heater, and heating power is certain.When start-up operation, since heating power has
Limit, heating rate is slow, and with the progress of heating, heated member constant temperature rises, need to generally increase on being heated component
Temperature sensor controls temperature.When heater works, internal temperature is high, and heater life is low, in addition, heating system
Complexity, reliability are low.
Summary of the invention
The object of the present invention is to provide a kind of PTC ceramics heater, for solving complicated heating system, efficiency and reliable
The low problem of property.
PTC ceramics heater of the invention is successively fixed with insulated thermal insulating layer, the conduction on top on the inside of the cover board
The conductive sheet of piece, certain thickness PTC ceramics heating sheet and lower part is coated with insulation around the PTC ceramics heating sheet and leads
Hot glue.
The PTC ceramics heater is embedded in the base interior being heated and by thermally conductive glue sticking, and adds to pedestal orientation
Heat.
The conductive sheet is bonded in PTC ceramics heating sheet upper and lower surfaces by thin conducting resinl respectively.
The insulated thermal insulating layer is consistent with the size of cover board.
The invention has the advantages that making to contact reliable, heat transfer efficiency height, heating effect between heater assembly and the pedestal being heated
Fruit is good；Insulated thermal insulating layer is filled between cover board and heater assembly, and the heat for reducing heater assembly is conducted to cover board, is improved
Heater efficiency.
PTC ceramics heater structure of the present invention is simple, and heating rate is fast, and heating efficiency is high, long working life, reliability
Height, and there are self-regulated temperature characteristics, it is suitble to promote in dual-use field, there is biggish practical application value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of PTC ceramics heater of the present invention.
Specific embodiment
The present invention is described in further details below.
With reference to Fig. 1.PTC ceramics heater structure of the present invention includes cover board 1, insulated thermal insulating layer 2, conductive sheet 3, PTC ceramics
Heating sheet 4 and thermal plastic insulation 5.The conductive sheet 3 is bonded in PTC ceramics heating sheet 4 above and below by one layer of thin conducting resinl respectively
Surface is bonded in pedestal 6 by heat-conducting glue, and surrounding fills thermal plastic insulation 5, and insulated thermal insulating layer 2 is filled in cover board 1 and heating
Between device assembly.
Conductive sheet 3 forms the two poles of the earth of heating power supply, is face contact with PTC ceramics heating sheet 4, and contact is reliable；Heater group
Part is bonded in pedestal 6 by heat-conducting glue, and surrounding fills thermal plastic insulation 5, and the pedestal 6 for making heater assembly and being heated is indirect
Touching is reliable, and heat transfer efficiency is high, and heating effect is good；Insulated thermal insulating layer 2 is filled between cover board 1 and heater assembly, reduces heating
The heat of device assembly is conducted to cover board 1, improves heater efficiency.
