Low Flow Velocity,Fine-Screen Heat Exchangers and Vapor-Cooled Cryogenic Current Leads.

摘要

The design,construction,and testing of three compact,low temperature heat exchangers are reported. A method is given for the construction of a small (approximately = 20-cm exp 3volume) exchanger that can handle 6 g/s helium flow with low pressure drops (delta P/P = 10percent) and adequate heat transfer (N/sub tu/ = 3). The use of screen for simple,vapor-cooled current leads into cryogenic systems is also discussed. (ERA citation 04:016819)
