Description
Известна насадка дл регенераторов низкотемпературных холодильных газовых машин , изготовленна из тонкой медной проволоки диаметром до 0,03 мм или мелкой сетки. Применение такой насадки нрн температурах ниже 60°К неэффективно, так как теплоемкость медной проволоки или сетки с понил ением температуры резко падает. Увеличение количества насадки вызывает увеличение мертвого объема, что ухудшает работу машины .Known nozzle for regenerators of low-temperature refrigerating gas machines, made of thin copper wire with a diameter up to 0.03 mm or a fine mesh. The use of such a nozzle with a nrn temperature below 60 ° K is inefficient, since the heat capacity of a copper wire or mesh drops sharply with temperature decrease. Increasing the number of nozzles causes an increase in dead volume, which impairs the operation of the machine.
Предлагаема насадка отличаетс тем, что на металлическую сетку нанос т свинец, регенерируюш ,ий тепло. Это новышает эффективность холодильных машин.The proposed nozzle is characterized in that lead is applied to the metal mesh, regenerated, and heat. This boosts the efficiency of chillers.
При низких температурах теплоемкость свинца гораздо больше, чем меди. Например, при 15°К объемна теплоемкость свинца вAt low temperatures, the heat capacity of lead is much greater than that of copper. For example, at 15 ° K the bulk heat capacity of lead in
20 раз больше теплоемкости меди. Благодар этому насадка со свинцовым покрытием новышает эффективность холодильных газовых машин дл получени температуры ниже 60°К и уменьшает мертвый объем регенератора.20 times the heat capacity of copper. Due to this, the nozzle with a lead coating increases the efficiency of gas coolers for obtaining temperatures below 60 ° K and reduces the dead volume of the regenerator.
Насадку изготавл ют способом электролитического освннцевани стандартной металлической сетки. Экспериментальна проверка показал-а, что насадки содержат до 80% свинца .The nozzle is made by electrolytically refining a standard metal mesh. An experimental test showed that the nozzles contain up to 80% of lead.
