Summary of the invention
The object of the invention is to, a kind of Tao Jin mixed type PTC fast electric heater is provided, solve above technical problem.
Technical problem solved by the invention can realize by the following technical solutions:
Tao Jin mixed type PTC fast electric heater comprises a heat generating components, and described heat generating components is connected with two electrodes, it is characterized in that, described heat generating components comprises heating ceramic sheet and metal PTC heater strip or band.
One described electrode connects heating ceramic sheet one end, and the other end of described heating ceramic sheet connects described metal PTC heater strip or is with an end by conductor, and described metal PTC heater strip or the band other end connect another described electrode.
The present invention is after electric current flows into an electrode place, and through the heating ceramic sheet, then by conductor, flow through metal PTC heater strip or band flow to another electrode at last, finish whole loop.
The heating ceramic sheet that adopts in traditional ceramic PTC electric heater has the advantage to current limitation and limiting temperature, can play to the current temperature of electric heater the self feed back effect.The metal PTC heater strip of metal PTC electric heater or band then have the advantages such as stable performance, efficient height, life-span length.In addition, arbitrarily crooked, the moulding of heating part by metal PTC heater strip or band consist of can better adapt to installation environment.
By above-mentioned design, ceramic PTC electric heater heat generating components and metal PTC electric heater heating parts are carried out organic combination, making the present invention both have the metal PTC electrical heated appliance has the advantages such as stable performance, efficient height, life-span length, has again the current limliting of ceramic PTC electric heater and the advantage of limiting temperature.
Described conductor adopts the conducting strip of a strip, and a described electrode adopts pellet electrode; Described pellet electrode is attached to described heating ceramic sheet one end, and conducting strip one end of described strip is attached to the described heating ceramic sheet other end, and the conducting strip other end of described strip connects described metal PTC heater strip or is with an end;
The conducting strip both sides of described strip are provided with insulating barrier, described metal PTC heater strip or band are wound on the described insulating barrier outside on the conducting strip of described strip with spirality, by the conducting strip insulation of described insulating barrier and described strip, described metal PTC heater strip or the band other end connect described another electrode.Above-mentioned design, metal PTC heater strip or band are wound on outside the insulating barrier with spirality, and firing rate is fast, and homogeneous heating is reliable.
Crossing the coating technique filler between adjacent two described heating ceramic sheets connects.So that adjacent two heating ceramic sheets connect close and firm.
The mica insulation sheet that described insulating barrier preferably adopts mica sheet to make.The insulating capacity of mica material is strong, wear resistence and resistance to wear are good, can effectively prevent the contacting of conducting strip of metal PTC heater strip or band and strip as insulating barrier, avoids short circuit.
The length of the conducting strip of described strip is at least 3 times of length of described heating ceramic sheet.
Described metal PTC heater strip or be with equidistant being wound on outside the described insulating barrier.So that homogeneous heating.
Described metal PTC heater strip or strip length are at least 3 times of conducting strip of described strip.
Beneficial effect: owing to adopt technique scheme, the present invention had both had the metal PTC electrical heated appliance advantages such as stable performance, efficient height, life-span length, suitable for foldable forming had been arranged, and had again the current limliting of ceramic PTC electric heater and the advantage of limiting temperature.
