Abstract
Provided is a high temperature electrothermal film device belonging to the electrothermal technology field especially to a plate shaped electrothermal device. The utility model comprises an insulation vector an electrothermal film attached to the insulation vector, an electrode and a conductor connected on the electrothermal film. The utility model is characterized in that the insulation vector is divided into an upper insulation vector layer and a lower insulation vector layer. The eletrothermal film is arranged between the two layers of insulation vectors. The utility model is a closed integral structure the outer shell of which is insulated with no potential electric safety hazard at all. Also, the utility model can be combined with heated articles at will. Meanwhile, the utility model with a small volume, a fast thermal response, an intense thermal amount and a relatively little thermal dissipation can be used safely and reliably and can be widely used in all types of apparatus which need the thermal function.
Description
Technical field:
The utility model relates to a kind of high-temperature electric heat membrane module, and it belongs to the electric-heating technology field, particularly a kind of plate electric heater.
Technical background:
At present, use metal in the prior art, the Electric radiant Heating Film that semiconductor or other composite material are made is a lot.Electric radiant Heating Film is because easy to use, and heat transfer rate is fast, and thermal capacitance is little, and electric heating changes the efficient height and obtained extensive use.Particularly it can be made on the various carrier, and shape and size can random variation, becomes its main advantage.But Electric radiant Heating Film can not lasting stability ground high temperature resistant, particularly under oxidizing atmosphere and wet environment, lost efficacy easily.In addition, also there is hidden danger in the electric fail safe on Electric radiant Heating Film is used.Provide a kind of device for heating electric heating membrane in the technical scheme that No. the 95101735.7th, China Patent No., its concrete structure is to be made of insulating carrier that scribbles Electric radiant Heating Film and Electric radiant Heating Film power circuit.Scribble the electrothermal membrane insulative carrier back side and be used for heating, such structure is not accomplished heater totally-enclosed, can only partly solve the electric safety problem of Electric radiant Heating Film, still has potential safety hazard and problem that can not lasting stability work.
Technology contents:
The purpose of this utility model is to provide a kind of volume is less, thermal response is fast, caloric value is big, heat is loose less, the safe and reliable high-temperature electric heat membrane module of consumption.
The purpose of this utility model is achieved in that
A kind of high-temperature electric heat membrane module, it comprises insulating carrier, attached to the Electric radiant Heating Film on the insulating carrier be connected electrode, lead on the Electric radiant Heating Film, described insulating carrier is divided into insulating carrier layer and following insulating carrier layer, is provided with Electric radiant Heating Film between described two-layer insulating carrier.
Described insulating carrier is provided with electrode interface.
Between described insulating carrier and Electric radiant Heating Film, be provided with one deck glass glaze bed of material.
Described Electric radiant Heating Film is the pectination thick film.
Described insulating carrier is a thermal conductive ceramic.
Because the utility model is a sealed whole body structure, there is not electric fail safe hidden danger fully in casing insulation, can combine with heating object is random.And the utility model volume is less, thermal response is fast, caloric value is big, heat is loose, and consumption is less, safe and reliable, can be applied in widely among the various electrical equipment that need heating function.
Description of drawings:
Accompanying drawing 1 is the structural representation of insulating carrier, pectination electric heating thick film and electrode down of the present utility model
Accompanying drawing 2 is the A-A cutaway view of the utility model accompanying drawing 1
Accompanying drawing 3 is the insulating carrier structural representation of going up of the present utility model
Embodiment:
Be embodiment of the present utility model with accompanying drawing 1,2,3 below, the utility model be further detailed:
In the present embodiment, the utility model is by insulating carrier, constitute attached to the Electric radiant Heating Film on the insulating carrier and the electrode 2, the lead 1 that are connected on the Electric radiant Heating Film, insulating carrier is divided into insulating carrier layer 4 and following insulating carrier layer 3, is provided with Electric radiant Heating Film 5 between described two-layer insulating carrier; Described insulating carrier is provided with electrode interface 6; Be provided with a glass glaze bed of material 7 between insulating carrier 4 and the Electric radiant Heating Film 5 on described.Described Electric radiant Heating Film is selected the pectination thick film for use; Described insulating carrier uses alumina ceramic plate or other thermostable heat-conductive material, selects alumina ceramic plate in the present embodiment for use.At first Electric radiant Heating Film 5 is coated in down insulating carrier 3, promptly forms pectination power circuit thick film on the aluminium oxide ceramics, apply glass glaze 7 after high temperature burns till again and lump together high temperature with last insulating carrier 4 and burn till as a whole.On last insulating carrier 4, leave electrode interface 6, connect together, and combine with the formation of methods such as welding or crimping with external power supply with pectination thick film 5.Because the utility model is a sealed whole body, there is not electric fail safe hidden danger fully in casing insulation, can combine with heating object is random.Pectination thick film 5 can be processed into different shape, and main feature is to leave the gap between the thick film, is beneficial to heat radiation and conducts heat, and can provide electric conversion efficiency high device.
