Description
Technical field
The utility model relates to ptc heater technical field, refers in particular to a kind of novel low-voltage PTC thermistor safe heating device.
Background technology
PTC thermistor is the semiconductor resistor that a kind of typical case has temperature sensitivity, when exceeding certain temperature, its resistance value along with the rising of temperature be increasing of step evolution, its resistance value of semistor presents the increase of step evolution along with the rising of PTC thermistor body temperature, temperature is higher, resistance value is larger, PTC thermistor heating power is descending after powered up, finally stablize, firm power is relevant with service condition, same PTC heater, service condition is different, then power may differ several times.The faster then firm power that dispels the heat is larger, the higher then power of surface temperature of PTC is higher, and the reliability of existing PTC thermistor own is not high, useful life is very short, if assemble in addition improper, product there will be the situation such as power and temperature instability, makes in use there is potential safety hazard.Therefore, for overcoming the deficiency of above-mentioned technology and to design thermal-stable effective, use safety, can ensure a kind of novel low-voltage PTC thermistor safe heating device of the serviceability of heater, just inventor's problem to be solved.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel low-voltage PTC thermistor safe heating device, and its heating effect is stable and effective, and long service life, has good heat dispersion simultaneously, has extraordinary practical value.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of novel low-voltage PTC thermistor safe heating device, it is characterized in that: PTC fever tablet, metal electrode film that device comprises shell and arranges in the enclosure, described PTC fever tablet both sides are respectively arranged with metal electrode film, metal electrode film one end is connected with wire, wire outer setting has sleeve pipe, and metal electrode film outer setting has shell, and described wire one end is connected with metal electrode film, wire is through shell, and the wire outer wrap through housing parts has sleeve pipe.
Further, described shell can be the one in metal material or ceramic material.
Further, described metal electrode film material is aluminium, and described sleeve pipe material is silica gel.
Further, described outer casing bottom can include notch, is provided with spring in notch.
Further, outside described metal electrode film, Packed dielectric film can be set.
The utility model is compared in prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution: shell of the present utility model adopts ceramic or that metal substitute is traditional insulating tape, adopt the shell of pottery or metal, pottery or metal shell are slightly large, and heat radiation evenly, the useful life of heater can be ensured simultaneously, pottery or metal shell increase the contact area with PTC fever tablet simultaneously, can ensure good heat radiation, ensure that the thermal-stable of heater.
In the utility model on shell increase have notch design, notch indoor design has spring, the fever tablet of PTC can be made operationally to wait, can adjust position, make produce heating effect evenly.
