The design and construction of simple Linde hydrogen and helium liquefiers

摘要: Summary High Vacuum and low temperature techniques are closely related but the latter not widely used. In particular general methods for calculating efficiencies of heat exchangers used with small liquefiers seem to be usual stumbling block. These have been summarised. The advantages a resistance path gas discussed construction simple variation Hampson exchanger is given. By using Linde hydrogen helium experiments in corresponding ranges can carried out on limited scale without great expense or highly skilled workshop effort.
