Description
Technical field
The present invention relates to a kind of electric heating element, especially a kind of high heat-conducting ceramic film heating pipe.
Background technology
Public heater, most is uses heating wire to directly heat, or makes and have the immerging metal tube heater of insulating barrier and heat；Also have and use ceramic material to make film heater；The service life using heating wire in these heaters is the longest, owing to heating wire operationally temperature is the highest, there is certain risk, use the film heater that general ceramic material is made, unstable properties, is ensureing that long-time stable service condition power density heated below is difficult to break through 30W/cm2。
Summary of the invention
It is an object of the invention to improve the characteristic of this heater so that heater has the thermal conduction characteristic of more than 100W/m.k, dramatically increases heat-transfer rate, allow heater have the less temperature difference between heating surface and heating surface, the most more can increase the stability of heater.
The technical scheme is that and be achieved in that: the high-purity carborundum material at high temperature sintering using purity higher than 95% does base material, use the technology of high-temperature metallic oxide gaseous phase deposition, do the film heater that ag paste electrode is made simultaneously, owing to this high-purity carborundum material has the thermal conduction characteristic of more than 100W/m.k, the most high temperature resistant, acid-alkali-corrosive-resisting, nontoxic characteristic, the heater so made has working stability, power density is higher (readily exceeds very much 30W/cm2Above), high temperature resistant, acid-alkali-corrosive-resisting, nontoxic characteristic.Have been widely used at food, industry, civil area tool.
