DESIGN CONSIDERATIONS FOR MICROMINIATURE REFRIGERATORS USING LAMINAR FLOW HEAT EXCHANGERS.

Author(s) : LITTLE W. A.

Summary

CONVENTIONAL COUNTER FLOW HEAT EXCHANGERS ARE DESIGNED TO OPERATE WITH THE FLUID STREAMS IN TURBULENT FLOW. THE RESULTANT MIXING OF THE FLUID ALLOWS HEAT TO BE TRANSFERRED FROM THE WALLS OF THE EXCHANGER TO THE BODY OF THE FLUID. IF, HOWEVER, THE DIMENSIONS OF THE EXCHANGER ARE SUFFICIENTLY SMALL, ENOUGH HEAT MAY BE TRANSFERRED BY CONDUCTION ALONE THAT OPERATIONIN THE LAMINAR FLOW REGIME IS POSSIBLE. THE A. DISCUSSES THE DESIGN PARAMETERS OF A MICROMINIATURE JOULE-THOMSON CRYOGENIC REFRIGERATOR OPERATING IN THIS REGIME. SUCH OPERATION OFFERS THE ADVANTAGES OF SIMPLICITY OF DESIGN AND LOW NOISE. THE LATTER IS OF PARTICULAR ADVANTAGE FOR THE COOLING OF CRYOGENIC SENSORS.
