Description
Technical field
The utility model relates to a kind of semiconductor heat booster, particularly relates to a kind of microheater.
Background technology
Low-voltage PTC constent temperature heater only needs 3-24V voltage to get final product constant temp. warming, its principle be PTC thermistor power up rear self-heating heat up make resistance enter transition district, low-voltage PTC constent temperature heater surface temperature will keep steady state value, this temperature is only relevant with applied voltage with the Curie temperature of PTC thermistor, and substantially irrelevant with ambient temperature.
Ptc heater is exactly the heater element utilizing low-voltage PTC constent temperature heater constant temp. warming characteristics design.In middle low power heating occasion, the advantage that ptc heater tool conventional heating element is incomparable, the application in electric heating appliance is more and more subject to the favor of researching and developing engineer.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, constant temp. warming, the flames of anger, thermal conversion rate is high, minimum by power supply voltage influence, natural life-span is long microheater.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of microheater; comprise heating main body; described heating main body front end is provided with connection wire; inside is provided with PTC fever tablet; described PTC fever tablet comprises shell, and described shell up and down inner side is provided with symmetry electrode sheet, is provided with PTC thermistor between described electrode slice; described PTC fever tablet front end is connected with high temperature protection pipe, and described high temperature protection pipe is connected with high temperature wire.
Described PTC thermistor powers up intensification and enters transition district maintenance constant temperature, and spread out of by heat by high temperature wire, described high temperature protection pipe is used for the protection in delivered heat process, prevents the loss of heat in temperature transmitting procedure.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described heating main body is insulating ceramic materials, and described insulating ceramic materials has insulation, the characteristic such as high temperature resistant, for the insulation of PTC fever tablet and the protection of heating-up temperature.
Further, described electrode slice is aluminium electrode slice, and described aluminium electrode slice resistivity, conduction band are all lower, is conducive to exciting PTC thermistor to enter transition district, keeps constant temp. warming.
Further, described high temperature protection pipe is silica gel sleeve pipe, and high temperature wire closely wraps up by described silica gel sleeve pipe, because silica gel material has better insulating properties, flexibility, heat-resisting quantity, therefore effectively can prevent the loss of heat in transmittance process.
Further, described some heaters are connected in parallel by heater top lead wire terminal, effectively can increase heating power.
The beneficial effects of the utility model are: structure is simple, constant temp. warming, the flames of anger, thermal conversion rate is high, minimum by power supply voltage influence, natural life-span is long.
