Abstract
A low-cost gas passage system capable of controlling temperature comprises a power supply, a temperature controlling instrument, a semiconductor heating module, a K thermocouple and a heating band. The heating band is formed by a heating core, an insulating layer and an outermost-layer woven mesh-shaped sheath. The K thermocouple is pressed against one side of a pipe and is wrapped in the heating band. The K thermocouple detects the temperature of the pipe wall of a gas passage at all times and converts a temperature signal to an electric signal and the electric signal is transmitted to the input end of the temperature controlling instrument; the temperature control system is started; a preset temperature is input on the temperature controlling instrument and the temperature controlling instrument compares the preset temperature with the practical temperature; if the preset temperature is greater than the practical temperature, the temperature controlling instrument outputs a control signal to trigger the semiconductor heating module; the semiconductor heating module obtains the control signal, the output end is conducted, the semiconductor heating module is powered on for supplying power to the heating band until the practical temperature is greater than the preset temperature; and then the temperature controlling instrument stops outputting an control signal, the output end of the semiconductor heating module is non-conducted again, the heating band is in a power-off state and the temperature rise stops.
