Abstract:

The Interface Heat Exchanger Coldplate, Part Number 58A831057, is a two-circuit coldplate for the Gemini B coolant system. The purpose of the test was to determine the heat transfer coefficient from the interface surface of the coldplate to the coolant fluid in each circuit for the nominal environmental control system operating conditions. The heat transfer coefficient UA for the primary circuit, at 140 lbshr coolant flow, was 131 BtuhrF. For the secondary circuit at 140 lbshr the UA was 100 BtuhrF. Author
