The cavity for regulating the gas temperature is a pipeline for wrapping gas so as to regulate the temperature of the gas flowing through the cavity. The gas flow line is a component that makes up the chamber, for example: the chamber may be divided into at least two sections uniformly in a direction perpendicular to the direction of gas movement, and each section may be used as a gas flow line. The temperature adjusting device 101 is disposed in the gas temperature adjusting cavity, and specifically, may be disposed in each gas flow line respectively, and is configured to adjust a temperature of the gas flowing through each gas flow line. The central processor 102 may be in electrical communication with the temperature regulating device 101 for controlling the temperature regulating device 101 to measure and regulate the temperature of the gas in each of the gas flow lines. The target preset temperature is a preset temperature value or temperature range of the gas that finally flows out of the cavity.
Optionally, each of the at least two temperature adjustment devices 102 is configured to adjust the temperature of the gas flowing through the corresponding gas flow pipeline to the pipe flow temperature corresponding to the gas flow pipeline, so that the temperature of the gas output through the cavity reaches the target preset temperature.
Wherein the tube flow temperature is a preset gas temperature value or temperature range within each gas flow line.
Specifically, the central processing unit 102 may determine the pipe flow temperature in each gas flow pipeline and send the pipe flow temperature to the corresponding temperature control device 101, so that the temperature control device 101 compares the measured gas temperature with the pipe flow temperature set in each gas flow pipeline after measuring the gas temperature in each gas flow pipeline. If the measured gas temperature does not match the pipe flow temperature, the temperature adjustment device 101 may adjust the gas temperature in the gas flow pipes to make the gas temperature in each gas flow pipe match the pipe flow temperature, and further make the temperature of the gas finally flowing out of the chamber reach the target preset temperature.

The benefits of this are: if the temperature in the gas flow line does not match the pipe flow temperature, there is sufficient time to adjust the gas temperature in the gas flow line. The first temperature sensor 10131 at the inlet of the chamber measures the gas temperature at the inlet of the chamber and sends this temperature to the cpu 102 via the temperature controller 1011. The cpu 102 determines the pipe flow temperature of each gas flow pipeline according to the received gas temperature at the inlet of the cavity and the flowing time of the gas flowing through the cavity, and sends the pipe flow temperature of each gas flow pipeline to the temperature controller 1011 corresponding to the pipe flow temperature, so as to ensure that the temperature of the gas flowing through the cavity can match the target preset temperature. When the temperature controller 1011 receives the pipe flow temperature corresponding to the current gas flow pipeline, the inlet temperature of the current gas flow pipeline measured by the first temperature sensor 10131 of the current gas flow pipeline is obtained, if the inlet temperature of the current gas flow pipeline does not accord with the pipe flow temperature, a control signal is generated and sent to the temperature adjustment actuator 1012 to adjust the gas temperature in the current gas flow pipeline. When the temperature adjustment actuator 1012 receives the control signal, the temperature of the gas in the gas flow line is adjusted, which may be temperature rise adjustment or temperature drop adjustment.

The temperature rapid-decrease curve comprises temperature information corresponding to each moment and is used for representing the change situation of the temperature along with the time.
Specifically, a temperature decrease curve can be determined by using a solution of the steepest decrease line problem according to the inlet gas temperature of the cavity, the target preset temperature and the flowing time of the gas flowing through the cavity, so as to determine the temperature to which the gas in the cavity needs to reach at each moment.

Optionally, when the gas temperature is higher than the pipe flow temperature, the gas temperature can be reduced by using compression refrigeration, and when the gas temperature is lower than the pipe flow temperature, the gas temperature can be increased by using a resistance wire. And then, the temperature of the gas output by the cavity reaches the target preset temperature.
Through using central controller, temperature controller and steepest speed reduction curve, can carry out quick accurate regulation to the gas temperature to make the gas temperature of cavity exit invariable predetermines the temperature at the target. The method has the advantages that: when the gas temperature at the inlet is changed frequently and obviously, the method still has the characteristics of strong robustness and quick response, and can accurately control the gas temperature at the outlet of the cavity to be at the target preset temperature.
