表面型PTC加热器热阻的研究和应用

Study and Application of Surface PTC Heater's Thermal Resistance

相同PTC元件,高的发热功率及高的加热器表面温度,极大程度取决于加热器的热阻.表面发热的方式使PTC发热元件及其它表面型加热器低热阻化.表面型PTC加热器具有许多优点,其应用与开发具有一定的意义.

For the same PTC element, the high thermal power and the surface temperature of the heater are determined, for the most part, by the thermal resistance of the heater. The fashion of surface heating allows the PTC heating element and other surface heater lower thermal resistance, there are many merits for surface PTC heater, and its applications and developments are significant.
