tube cooler

基本解釋

Using single stage version PTC to reach the temperature below 30 K is a difficult task for high frequency pulse tube cooler.
采用單級(jí)高頻脈沖管制冷機(jī)獲得低于30 K的制冷溫度是脈沖管應(yīng)用的一個(gè)新方向。
A lowest no-load temperature of 13.8 K has been obtained for the first stage without thermal connector, which is a new record for the single-stage pulse tube cooler.
在沒有熱橋連接的情況下，單獨(dú)測(cè)試第一級(jí)最低制冷溫度達(dá)到13.8 K，這是單級(jí)脈管制冷機(jī)獲得的最低制冷溫度新紀(jì)錄。
Use single stage version to reach the temperature of 20 K is a difficulty for high frequency pulse tube cooler(PTC). Multi-stage version is a popular method to reach the low temperature.
單級(jí)高頻脈沖管制冷機(jī)直接降低到20 K以下溫區(qū)存在很大困難，采用多級(jí)方案是高頻脈沖管制冷機(jī)獲得更低溫度的主要方法。
