Abstract

The invention relates to the technical field of temperature control, and discloses a constant temperature device based on a phase-change material. The constant temperature device comprises a constanttemperature container, a heater, temperature sensors and a controller; the body of the constant temperature container is of a double-layer structure, and the double-layer structure is filled with thephase-change material; the heater is packaged in the double-layer structure and can heat the phase-change material; the temperature sensors are packaged in the double-layer structure and can detect the temperature of the phase-change material in real time; and the controller is electrically connected with the heater and the temperature sensors, wherein the according to the temperature of the phase-change material detected by the temperature sensors , the controller compares the temperature of the phase-change material with the preset temperature of the phase-change material, and the heater iscontrolled to start and stop according to a comparison result. The constant temperature device has the advantages that the constant temperature environment precision is high, the structure is simple,the device is easy to operate, energy consumption is reduced, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a constant temperature device based on a phase change material. Background technique [0002] In the process of scientific experiments, analysis and testing, etc., the more stable the temperature of the sample, the more accurate data and measurement results can be obtained. With the advancement of science and technology and the improvement of testing standards, the requirements for the temperature stability of the sample space are getting higher and higher. For example, the temperature accuracy is usually ±0.1°C, ±0.01°C, or even a high temperature control of ±0.001°C. precision. However, temperature is a nonlinear control object with large inertia and pure hysteresis, and the parameters of the temperature control system are not easy to determine, making high-precision temperature control very difficult. Traditional high-precision temperature control is mainly based...
