Изобретение относитс к холодильной технике и предназначено преимущественно дл охлаждени приемников излучени .The invention relates to refrigeration engineering and is intended primarily for cooling radiation detectors.
Известен тv икpoxoлoдильник сш охлаждени приемников излучени , содержащий расположенный в корпусе трубчатый теплообменник с дроссельным отверхзтием на Холодном конце и подвижную иглу дл изменени площади проходного сечени , в котором регулирующа игла закреплена на планке, соединенной с корпусом при помощи т г fl.There is a known tv ice cell cooling module for cooling of radiation receivers, which contains a tubular heat exchanger located in a housing with a throttle upper end at the Cold end and a movable needle for changing the cross section area, in which the regulating needle is fixed on a bar connected to the housing using fl.
Недостатком известного микрохолодильника вл етс длительный период выхода на рабочий режим в результате наличи в холодильной зоне увеличенной охлаждаемой массы.A disadvantage of the known microcooler is the long period of reaching the operating mode as a result of the presence in the refrigerating zone of an increased cooled mass.
Цель изобретени - упрощение конструкции и сокращение времени выхода микрохолодильника на рабочий режим.The purpose of the invention is to simplify the design and reduce the time for the micro-refrigerator to reach the operating mode.
Это достигаетс тем, что холодный конец теплообменника выполнен в виде упругого элемента, прикрепленного к корпусу при помощи струны, а игла закреплена на сердечнике .This is achieved by the fact that the cold end of the heat exchanger is made in the form of an elastic element attached to the body by means of a string, and the needle is attached to the core.
При этом струна выполнена из материала с болыиим коэффициентом линейного расщцрени , чем материал иглы и сердечника.In this case, the string is made of a material with a higher linear rasterization coefficient than the material of the needle and core.
На чертеже представлен микрохолодильник. В корпусе 1 микрохолодильника, имеющем штуцер 2 дл подвода хладагента и щтуцер 3 дл отвода хладагента, закреплен криостат 4 с охлаждаемым объектом 5. Внутри криостата 4 размещен трубчатый теплообменник 6, навитый на сердечник 7.The drawing shows a microcooler. A cryostat 4 with a cooled object 5 is fixed in the case 1 of the microcooler with a fitting 2 for supplying the refrigerant and a brush 3 for discharging the refrigerant. Inside the cryostat 4 there is a tubular heat exchanger 6 wound on the core 7.
Холодный конец теплообменника 6 выполнен в виде упругого элемента 8, например спиральной пружины, и прикретшен струной 9 к корпусу 1, Игла 10, перекрывающа дрос- сельное отверстие 11, неподвижно прикреплена к внутренней стороне сердечника 7,The cold end of the heat exchanger 6 is made in the form of an elastic element 8, for example a coil spring, and is attached by the string 9 to the body 1, the Needle 10, blocking the throttle hole 11, is fixedly attached to the inner side of the core 7,
С целью повышени технологичности холодный конец теплообменника может быть выполнен из нескольких упругих элементов, соединенных между собой и с теплообменником через коллектор.In order to improve processability, the cold end of the heat exchanger can be made of several elastic elements connected to each other and to the heat exchanger through the manifold.
Микрохолодильник работает следующим образокиMicro-fridge works as follows
Хладагент под давлением подводитс че- рез щтуцер 2 в теплообменник 6, дросселиThe refrigerant under pressure is fed through shtutser 2 to heat exchanger 6, throttles
