Temperature control device, method and system

Abstract

The invention provides a temperature control device, method and system and relates to the technical field of temperature control. The device is arranged on the outer side of a pipeline in a winding manner through a heating assembly. The portion between the heating assembly and the pipeline is filled with a phase change heat storage material. A first temperature sensor is arranged on the inner wallof the pipeline and used for measuring the temperature of fluid in the pipeline. A second temperature sensor is arranged on the outer wall of the heating assembly and used for measuring the outside environment temperature of fluid outside the pipeline. A control circuit is electrically connected with the heating assembly, a heat dissipating assembly, the first temperature sensor and the second temperature sensor. After the fluid needing temperature control enters the pipeline, when temperature rising or temperature lowering is needed, according to the set temperature and the fluid temperaturemeasured by the first temperature sensor, the control circuit can drive the heating assembly or the heat dissipating assembly to work, and by means of the assisting function of the second temperaturesensor and the phase change heat storage material, in the fluid temperature control process, the phenomenon that the actual temperature surpasses the set temperature can be avoided.

Description

technical field

[0001] The present application relates to the technical field of temperature control, in particular to a temperature control device, method and system. Background technique

[0002] Temperature represents the degree of hot or cold of an object, and its definition is given by thermodynamics. It is closely related to human life, industrial and agricultural production, and scientific research. There are almost no production processes and scientific research that do not require temperature control. Therefore, temperature control devices are widely used. It is used in many fields such as metallurgical industry, chemical production, electric power engineering, paper industry, machinery manufacturing and food processing.

[0003] Existing temperature control devices are mainly based on a proportional-integral-derivative (Proportion Integral Differential, PID) circuit, and the temperature control device is controlled by the PID circuit to reach a preset temperature v...
