(54) РАБОЧАЯ СМЕСЬ ДЛЯ ДРОССЕЛЬНОГО МИ КРО ХОЛОДИ ЛЬНИ К А(54) WORKING MIXTURE FOR THROTTLE MI KRO COLD CUT TO A

Изобретение относитс  к технике низких температур, а именно, к рабочим телам дл  дроссельных микрохолодильников, работающих по разомкнутым циклам в диапазоне 14О-17О К. Микрохолодильники такого типа ваход т применение дл  кратковременно гО охлаждени  объектов с небольшими тепловыми выделени ми, например приемников инфракрасного излучени . Известны рабочие тела дл  дроссельных микрохолодильвЕков, преоставл юшие собой либо чистые вещестыа (азот, аргон), либо многокомпонентные смеси (например, азоч фреоноаые ). Указанные вещества н смеси используютс  в микрохолокильвиках ОЛЯ по- лучевн  температур в диапазоне 65-1ОО°К. jЗл  получени  более высоких температур (145°К) примен етс  фреон-14 ( С Р). При использовании фреона-14 в дросселк ных микрохолоаш1ьнюсах, работа1йшнх с накоплеввем рабочего тела после просселнровавв ,. в накопителе вынуждены примен ть раалвчвые пористые ваЬадки дл  уоержавнЗ жвдасоста, Е1следств11в..того, что объем на копсггел  заполнев васадкой, значительно уменьшаетс  количество жидкости в нем, а, следовательно, в врем  автономной работы микрохолодильввка после прекращени  поовчв газа. Целью изобретени   вл етс  разработка новой рабочей смеси дл  увелнченн  продолжительности автон лвого режима и расшвреви  получеввых температур. Это достигаетс  тем, что в состав смеси пополвнтельво введевы аргон в углекислота в ее комповевты вз ты в следуюшвх соотношени х, моль %:,- Фреов-1460-8О Аргон15-ЗО Углекислота5-1О Варьиру  коваевтрапии компонентов в указаввых пределах, можно получить требуемую температуру охлаждени  в диапазоне 14О-170К. Критическве температуры прв этом ввже 223К. Рабоча  смесь после дросселировани  образует в вакопителе прв атмосферном давлевви твердую сублимирующую фазу, .котора  удерживаетс  в его обьеме без специальной васадкв. При исполь зовании рабочей смеси увеличиваетс  вре м  автономной работы накопител .The invention relates to a low temperature technique, namely, working bodies for choke micro coolers operating in open-loop cycles in the range of 14O-17O K. Micro-coolers of this type are used for short-term cooling of objects with small thermal emissions, for example, infrared radiation receivers. Working bodies are known for choke microcooles, which are either pure substances (nitrogen, argon), or multicomponent mixtures (for example, freonoy hydrogen). These substances and mixtures are used in the microholies of the OLA at temperatures in the range of 65-1OO ° K. З Freon-14 (C P) is used to obtain higher temperatures (145 ° K). When using freon-14 in the Drossel microholochies, it works with the accumulation of the working fluid after it has been distributed. in the accumulator, we have to use real porous va- ces for wagons, because of the fact that the volume on the copshel is filled up with the packing, the amount of liquid in it is significantly reduced, and, consequently, during the autonomous operation of the microcooler after the gas has stopped. The aim of the invention is to develop a new working mixture for increasing the duration of the autonomous mode and diluting the obtained temperatures. This is achieved by the fact that the composition of the mixture by introducing argon into carbon dioxide into its composites is taken in the following ratios, mol%: - Freov-1460-8O Argon15-ZO Carbonic acid5-1O Varya Kovarayarapii components within specified limits, you can get the required temperature cooling range 14O-170K. The critical temperature for this is 223K. The working mixture, after throttling, forms a solid subliming phase in the evaporator ppv of the atmospheric pressure, which is kept in its volume without a special vasadq. When using the working mixture, the battery autonomy is increased.
