Abstract

The invention discloses a universal split type linear stirling refrigerator driving method and driving circuit. The universal split type linear stirling refrigerator driving method comprises the steps that the temperature of a temperature diode is collected through a digital signal processing (DSP) chip; a corresponding control signal is determined according to the temperature; and a refrigerator is controlled through the control signal to conduct refrigeration. It is proved through actual measurement that the temperature control precision is higher than that of an existing analog circuit driver by one magnitude order, and the high-temperature and low-temperature adaptability of the driving method and driving circuit is excellent; a set point changes within + / -2.0 mV when the environment temperature ranges from -40 DEG C to +71 DEG C; under a steady-state condition, the fluctuation of a temperature control point is smaller than 5 mV in a short interval of one second, and the fluctuation of a temperature control point is smaller than 0.15 mV in a long interval of ten minutes.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a driving method and a driving circuit of a general split linear Stirling refrigerator. Background technique [0002] The infrared photosensitive device used in the infrared detector is very sensitive to the working temperature. After the infrared detector is cooled at a low temperature, the response time is shortened, the sensitivity is improved, the response wavelength is broadened, the limited background noise is reduced, and the infrared imaging effect is greatly improved. The working performance of the refrigerator directly restricts the imaging effect of the cooled infrared detector. With the rapid development of infrared technology, high-resolution, large field of view, and large area array infrared detectors have gradually become the mainstream, and infrared detectors are more widely used in portable devices and aerospace fields. The current refrigerator controller...
