Abstract
The utility model relates to a safety energy-saving electric heater for laboratory use, which comprises an outer shell and an electric heating device arranged in the outer shell. The electric heating device has a ceramic membrane structure. The ceramic membrane structure is composed of a ceramic membrane made by an insulating substrate and the semiconductor material which is coated on the insulating substrate and a pair of electrodes which are arranged on the membrane surface of the insulating substrate. The ceramic membrane made from the semiconductor material is a novel electric heating material without fire, and the heating temperature can reach 600 DEG C. Compared with existing electric heating device, safety energy-saving electric heater for laboratory use is safer and can save more than 10% electric energy. The utility model can be widely used in various laboratories, in particular to the laboratory which forbids the fire severely.
Description
The utility model belongs to the laboratory heater, particularly a kind of electric heater.
Existing various laboratories are naked light with heater (electric furnace, alcolhol burner etc.), even in the strict chemical experiment of prohibiting fire, also are that the heating wire with glass fibre covering heats, so both dangerous during experimental implementation, consume energy again.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of electric heater of the flames of anger is provided, and this kind electric heater is safety not only, and energy-conservation.
The electric heater of realizing the utility model purpose comprises shell and installation electric calorifie installation in the enclosure, electric calorifie installation is the multiple membrane type structure of pottery, form at multiple film of the pottery that the semi-conducting material on the insulating body is made and the pair of electrodes that is arranged on the multiple film of insulating body by insulating body, coated, the multiple film of the pottery that semi-conducting material is made is a kind of novel flames of anger thermo electric material, and heating temp can reach about 600 ℃.
For easy to assembly, improve security and service life, shell of the present utility model is a fabricated structure, is made up of loam cake and base, the insulating body outer surface is topped protective cover.
The utlity model has following advantage:
1. make heater owing to adopt pottery to answer film, thereby the adstante febre flames of anger, thermal efficiency height is compared with the common electrical heated filament, under equal conditions can save energy more than 10%.
It is 2. simple in structure, easy to assembly,
3. the topped protective cover of insulating body outer surface can make electric calorifie installation be in full closeding state to help improving security and service life,
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof,
