Since there is no need to provide a temperature sensor outside the housing 5, the present invention is not affected by animal movements, and can prevent animals from damaging the temperature sensor or the signal transmission path.
According to the law of conservation of energy, the temperature rise value of the temperature inside the temperature controller relative to the environment is in direct proportion to the power consumption of the temperature controller; the temperature rise value relative to the environment in the temperature control range is in direct proportion to the working power of the heating element; it is known from Joule's law that the temperature of the power amplifying unit 9 and the two temperature sensors 10 immediately adjacent to the periphery is proportional to the average current passing through the power amplifying unit 9.
