Abstract
The utility model provides a combined tubular electrothermal film heater, which adopts electrothermal films to heat a flowing air medium, and the combined tubular electrothermal film heater has the advantages of high calorific efficiency and long service life. The combined tubular electrothermal film heater is in a combined tubular structure, the combined tubular electrothermal film heater comprises a plurality of concentric circular tubes with different diameters, a connecting rid plate is provided between the circular tubes, the surfaces of all the circular tubes and the connecting rid plates are covered with an electrothermal film, and the electrothermal films at the two end faces of the tubular heater are coated with a conductive electrode used to connect an external power source. The circular tubes and the connecting rid plates adopt ceramic materials, quartz materials, carbofrax materials, nucleated glass materials and other bisilicate materials. When the combined tubular electrothermal film heater is used, the power source is switched on, and the electrothermal films can generate heat; meanwhile, the air flowing from the axial gap of the tubular heater is heated. The utility model has the advantages of high calorific efficiency, long service life, fluent air passage, simple structure, convenient manufacture, etc. The combined tubular electrothermal film heater is suitable to small household electric appliances such as electric hair blowers, etc. The combined tubular electrothermal film heater is also suitable to the industrial application.
Description
Technical field:
The utility model relates to a kind of device with the moving air dielectric heating of Electric radiant Heating Film convection current, relates in particular to a kind of combined type tubulose electrothermal film heater.
Background technology:
Existing moving air electric heater unit has a variety of, as: metal tube heater, strip heater, PTC ripple heating element, PTC honeycomb heating element etc., but they exist following different shortcoming: thermal efficiency ratio is lower, and heating area is little, and the life-span is short.Also have a kind of PTC ripple heating element, PTC honeycomb heating element, its power stability is bad, uses the phenomenon that a period of time can the emergent power decay, medium by the time the resistance windage big.
The utility model content:
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of heating efficiency height, life-span long, adopts the combined type tubulose electrothermal film heater of Electric radiant Heating Film to the air dielectric heating of flowing.
The technical solution of the utility model is such:
A kind of combined type tubulose electrothermal film heater, it is a kind of combined type tubular structure with multiple pipe, it comprises N the pipe of Different Diameter with one heart, the dowel batten is arranged between the described pipe, surface and end face at all pipes and dowel batten are covered with Electric radiant Heating Film, are coated with the conductive electrode that is used to connect external power source on the Electric radiant Heating Film of two end faces of tubular heater.
The quantity N of described pipe and dowel batten is 〉=2 integer.
Described pipe and dowel batten adopt silicates materials such as pottery, quartz, carborundum, devitrified glass.
It is Electric radiant Heating Film or resistance heating film that described Electric radiant Heating Film can adopt semiconductor thermoelectric film, ceramic glaze Electric radiant Heating Film, carbon, and available immersion plating, barrel plating or process for chemical vapor deposition of materials with via are made.
Described electrode is formed by electrocondution slurries such as silver, silver-colored palladium, silver-colored platinum, gold sintering after dipping, brushing.
The external diameter of described combined type tubular heater is generally: 20mm-1000mm.
