Abstract
The utility model provides an electric direct heater. A resistance belt 4 made of the spiral nickel-chromium alloy of the utility model is coiled on the outer surface of a ceramic insulation core 5. Each spiral ring of the resistance belt is separated by the side teeth of the ceramic insulation core. A stainless steel bracket 1 penetrates through the through hole of the center of the ceramic insulation core. Two ends of the resistance are power supply connection ends. The resistance belt is switched, the electric energy is converted to the heat energy and the heat energy directly heats the ambient air, so the utility model has the high thermal efficiency. The utility model has the characteristics of electric energy saving, no easy short circuit, convenient overhauling, long service lift, etc.
Description
What the utility model provided is a kind of Electric direct heater.Belong to the electric heating appliance technical field.
Existing electric heater structure is that resistance wire is contained in the hollow metal tube.Fill insulant between resistance wire and the tube wall.The tube wall appearance is wound with the spiral metal fin, can increase area of dissipation.After the energising, the heat that resistance wire produces is delivered to tube wall and fin by insulating material, again the air of circumference.Mode of heating is indirect.Its heat efficiency is low, and heating wire is normal off also, and useful life is short.
The purpose of this utility model is the defective at above-mentioned existence, proposes the Electric direct heater of a kind of heat efficiency height, long service life.
Technical solution of the present utility model: structure as shown in drawings.Spiral nichrome resistive band 4 is to be coiled on the outer surface of ceramic insulation core 5, separated by the side tooth 2 of ceramic insulation core between each spiral coil of resistive band, through hole in the middle of the ceramic insulation core penetrates stainless steel stent 1, and two end points of resistive band are supply terminalss.
Owing to adopted direct mode of heating, and the spiral shape surface of resistive band can play the effect with fin, thereby the characteristics that the utlity model has heat efficiency height, save electric energy.In addition, the utility model also has the advantage that is difficult for short circuit, maintenance convenience, long service life.
Accompanying drawing 1,2 is respectively that master of the present utility model looks, the side-looking structural representation.
Among the figure 1 is stainless steel stent, the 2nd, and side tooth, the 3rd, power supply terminal, the 4th, nichrome resistive band, the 5th, ceramic insulation core.
Spiral nichrome resistive band is coiled in ceramic insulation core outside.Separated by the side tooth of ceramic insulation core between the resistive band, can avoid short circuit current.Through hole in the middle of the ceramic insulation core penetrates stainless steel stent, is used for the installation of electric heater.After the resistive band energising, convert electric energy to heat energy, directly the air of circumference.
