A dual combination self-control thermostatic type electric heater includes a heating part which is connected with the two electrodes and includes a heating ceramic chip and a heating wire. One electrode is connected with one end of the heating ceramic chip, the other end of the heating ceramic chip is connected with one end of the heating wire via a conductor, and the other end of the heating wire is connected with the other electrode. Because of the adoption of the above technical scheme, the dual combination self-control thermostatic type electric heater not only has the advantages of stable performance, high efficiency, long service lifetime, and bent shaping of a metal PTC electric heater, but also has the advantages of the current limitation and the temperature limitation of a ceramic PTC electric heater.
Description
Technical field
The utility model relates to the air-conditioning technical field of heating, is specifically related to a kind of electric heater.
Background technology
Electric heater is divided into two kinds usually, traditional ceramic PTC electric heater and up-to-date metal PTC electric heater.Pottery PTC electrical heated appliance has the advantage of current limliting and limiting temperature, but it has the shortcoming of power attenuation.
The metal PTC electrical heated appliance has advantages such as stable performance, efficient height, life-span be long, but the metal PTC electric heater adds that to pine for surface temperature higher in that small size is high-power.
The utility model content
The purpose of the utility model is, a kind of two combination self-control thermostatic type electric heater is provided, and solves above technical problem.
The technical problem that the utility model solved can adopt following technical scheme to realize:
Two combination self-control thermostatic type electric heaters comprise a heat generating components, and said heat generating components is connected with two electrodes, it is characterized in that, said heat generating components comprises heating ceramic sheet and heater strip; Said heater strip adopts the metal PTC heater strip.
One said electrode connects heating ceramic sheet one end, and the other end of said heating ceramic sheet connects said metal PTC heater strip one end through conductor, and the said metal PTC heater strip other end connects another said electrode.
The utility model is after electric current flows into an electrode, and through the heating ceramic sheet, through conductor, the metal PTC heater strip of flowing through flow to another electrode at last, accomplishes whole loop then.
The heating ceramic sheet that is adopted in traditional ceramic PTC electric heater has the advantage to current limitation and limiting temperature, can play the self feed back effect to the current temperature of electric heater.The heater strip of metal PTC electric heater then has advantages such as stable performance, efficient height, life-span length.
Through above-mentioned design; Ceramic PTC electric heater heating parts and metal PTC electric heater heating parts are organically combined; Making the utility model both have the metal PTC electrical heated appliance has advantages such as stable performance, efficient height, life-span length, has the current limliting of ceramic PTC electric heater and the advantage of limiting temperature again.In addition, arbitrarily bending, the moulding of heating part by the metal PTC heater strip constitutes can better adapt to installation environment.
Said conductor adopts the conducting strip of a strip, a said electrodes use pellet electrode; Said pellet electrode is attached to said heating ceramic sheet one end, and conducting strip one end of said strip is attached to the said heating ceramic sheet other end, and the conducting strip other end of said strip connects said heater strip one end;
The conducting strip both sides of said strip are provided with insulating barrier; Said metal PTC heater strip is wound on the said insulating barrier outside on the conducting strip of said strip with spirality; Through the conducting strip insulation of said insulating barrier and said strip, the said metal PTC heater strip other end connects said another electrode.Above-mentioned design, the metal PTC heater strip is wound on outside the insulating barrier with spirality, and firing rate is fast, and homogeneous heating is reliable.
The mica insulation sheet that said insulating barrier preferably adopts mica sheet to process.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 and strip as insulating barrier, avoids short circuit.
Beneficial effect: owing to adopt technique scheme, the utility model 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 the current limliting of ceramic PTC electric heater and the advantage of limiting temperature again.
