Description
(54) УСТРОЙСТВО ДЛЯ ПОЛУЧЕНИЯ НИЗКИХ (54) DEVICE TO RECEIVE LOW
Изобретение относитс к криогенной технике , а именно к устройствам дл получени температур в диапазоне от сверхнизких до гелиевых.The invention relates to a cryogenic technique, namely, devices for producing temperatures in the range from ultra low to helium.
Известно устройство дл получени низких температур растворением гели -3 в гелии-4) содержащее соединенные посредством теплообменников камеры испарени и растворени и проход щий через камеру испарени и перекрытый пробкой канал дл ввода охлаждаемого образца в камеру растворени 1 .A device for obtaining low temperatures by dissolving helium-3 in helium-4 is known. It contains evaporation and dissolution chambers connected by means of heat exchangers and passing through the evaporation chamber and blocked by a stopper channel for introducing the sample to be cooled into the dissolution chamber 1.
Недостатком данного устройства вл етс относительно низка холодопроизводительность.The disadvantage of this device is the relatively low cooling capacity.
Цель изобретени - повышение холодопроизводительности .The purpose of the invention is to increase the cooling capacity.
Указанна цель достигаетс тем, гго в канале над пробкой дополнительно установлен радиационный экран, а камера растворени имеет тепловой контакт со стенками канала.This goal is achieved by the fact that a radiation screen is additionally installed in the channel above the plug, and the dissolution chamber has thermal contact with the channel walls.
На чертеже приведена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство содержит теплообменники 1, камеру 2 испарени и камеру 3 растворени , пробку 4, канал 5, охлаждаемый образец 6, ТЕМПЕРАТУРThe device contains heat exchangers 1, evaporation chamber 2 and dissolution chamber 3, plug 4, channel 5, sample 6 to be cooled, TEMPERATURE
радиационный зкран 7, дроссель 8, тракт 9 откачки камеры испарени , дополнителы&ш тракт 10 откачки,штангу 11, уплотнение 12, теплообменник 13 и линию 14 конденсации.radiation screen 7, choke 8, path 9 for pumping evaporation chamber, additional & pump path 10, rod 11, seal 12, heat exchanger 13 and condensation line 14.
Устройство работает следующим образом.The device works as follows.
Штанга 11с укрепленными на ней образцом 6, пробкой 4 и радиационным зкраном 7 загружаетс в тракт 10 либо при комнатной температуре, либо после охлаждени устройства до температуры кипени жидкого азота. The rod 11c with the specimen 6 fixed on it, the stopper 4 and the radiation screen 7 is loaded into the path 10 either at room temperature or after cooling the device to the boiling point of liquid nitrogen.
П После загрузки образца пробка 4 привинчиваетс винтами к верхней части камеры 3 растворени ее полной герметизации, например индиевым уплотнением 12. Ниже пробки расположена камера 3 растворени , выше - канал After loading the sample, the stopper 4 is screwed to the upper part of the dissolution chamber 3, it is completely sealed, for example with an indium seal 12. The dissolution chamber 3 is located below the stopper, the channel is above
II 5, где собираетс моноизотопиый гелий . Между камерой 3 расвторени и каналом 5 есть тепловой контакт благодар теплообменнику 13, который имеет большую поверхность контакта с хладагентом. В простейшем случае таким теплообменником могут служить стенки камеры расгворени и сборника, выполненные из Материала с высоким значением коэффициента теплопроводности. В канал 5, незапиII 5 where monoisotopic helium is collected. Between the chamber 3 and the channel 5 there is a thermal contact due to the heat exchanger 13, which has a large contact surface with the refrigerant. In the simplest case, such walls can be the walls of the opening and collection chambers made of a Material with a high value of thermal conductivity. In channel 5, nepi
