Embodiment Construction

[0021] Figure 1~6 The refrigeration system for infrared detectors shown in the present invention includes a gas storage bottle 6, which has two mutually independent first gas storage chambers 2 and second gas outlet chambers 12, the first gas storage chamber 2 and the second gas outlet chamber. The gas storage chamber 12 is respectively provided with an air inlet and an air outlet. The air inlets of the two gas storage chambers are respectively sealed and fixed with inflatable check valves 1 and 11, and the gas outlet of the first gas storage chamber 2 is fixedly installed. There is a first electric explosion opening valve 3 that controls the discharge of gas in the first gas storage chamber 2, and a valve that controls the discharge of gas in the second gas storage chamber 12 is fixedly installed at the gas outlet of the second gas storage chamber 12. The second electric explosion opens the valve 3, and a pressure relief valve 14 is communicated with the second electric expl...

Abstract

The invention relates to a refrigeration system used in an infrared receiver, which comprises a gas tank and a valve used for controlling the efflux of gas in the gas tank; wherein the gas tank is internally provided with a first gas storage cavity and a second storage cavity which are mutual independence and both provided with air inlets and air outlets; the two air inlets are both sealed and provided with a gas charging retaining valve; and the two air outlets are both provided with the valves used for controlling the efflux of the gas in the gas tank; the valves are electrical explosion opening valves which comprise a first electrical explosion opening valve and a second electrical explosion opening valve; the first electrical explosion opening valve is communicated with the first gas storage cavity; and the second electrical explosion opening valve is communicated with the second gas storage cavity; the air outlet of the second electrical explosion opening valve is communicated with a reducing valve, the air outlet of the reducing valve and the air outlet of the first electrical explosion opening valve are both communicated with different air inlets of a gas circuit diverter valve. The refrigeration system adopts bipolar refrigeration, has long refrigeration time and good refrigeration effect and meets the operating requirements for the infrared receiver with the high precision.

Description

technical field [0001] The invention relates to a refrigeration system for an infrared detector. Background technique [0002] High-performance infrared detectors require a low-temperature environment. Only in a low-temperature environment can their electronic devices or systems function normally, improve the sensitivity of electronic devices, shield or reduce thermal noise from the system itself or its surroundings, and make its signal noise has been substantially improved. At present, most of the infrared detector refrigeration systems known at home and abroad adopt a single-stage refrigeration mode, using a single refrigerant gas stored in a gas tank to cool the infrared detector. The existing refrigeration system has a small amount of gas storage, a single gas storage medium, a general cooling effect, a short cooling time, and a large volume and weight. For the new high-precision infrared detector, it cannot meet its application requirements. Contents of the invention...
