一、序言我们采用非常规材料和古典式热泵的运行参数制造了一种新型低温冷却器。其运行速度低、输入功率低、制冷量只有几毫瓦,其冷部件大部分使用塑料和非金属合成材料,构造简单。由于制冷量是如此的低,若不采取特别措施来缩短起动过程,那末从室温开始它们的起动过程就需要许多小时。这些低温冷却器的主要用途是冷却小型超导器件,如超导量子干涉仪
First, the preamble We use unconventional materials and classical heat pump operating parameters to create a new type of low temperature cooler. Its low operating speed, low input power, cooling capacity of only a few milliwatts, most of its cold parts using plastic and non-metallic synthetic materials, the structure is simple. Because of the low cooling capacity, many hours are required to start their process from room temperature unless special measures are taken to shorten the starting process. The main purpose of these cryogenic coolers is to cool small superconducting devices such as superconducting quantum interferometers
