The invention relates to cooling systems. A cooler unit for receiver of radiant energy of optoelectronic device comprises power source of cryogen 1, this is connected in sequence by pipelines 2 to electro-pneumatic valve (EPV) 3 and micro-refrigerator 4. The receiver of radiant energy (RRE) is connected in sequence to current-voltage transducer 6, buffer 7, fixation circuit for coming to mode RRE 8, circuit for one-time supply of cryogen 9, circuit for cyclic supply of cryogen 10, first input ofpower amplifier 11, and its output is connected to winding of EPV drive. The output of circuit of impulse supply of cryogen 9 is in sequence connected to the first input of circuit for start of cyclic supply of cryogen 12, and its output - to the second output of the power amplifier 11. This makes it possible to solve the problems of economy, reliability, and to increase time given for adjustment of optoelectronic device at operation with cryogen.
