Research Abstract

The wire-type microcooler developed in this work consists of a concentric counterflow heat exchanger and a capillary. The primary cooling process of the microcooler is the isenthalpic Joule-Thomson expansion at the capillary. The effects of refrigerant conditions, and dimensions and materials of the microcooler on the performance were examined by experiments and numerical analysis. The numerical analysis model represents the temperature drop and mass flow rate obtained in the experiments within 20% and 10%, respectively. A cooling power of 550 mW at an evaporator temperature of 271 K was attained by using carbon dioxide as a refrigerant at the inlet pressure of 3.0 MPa.
