Abstract
This study proposed a new type of printed circuit heat exchanger with rectangular microchannels and established a test platform with supercritical carbon dioxide as working fluid. The heat transfer and pressure drop of the test sample were tested, and the experiments considered inlet temperature ranges of 335.0–338.9 K and 316.1–339.1 K for the hot and cold sides, respectively. The results revealed that hot-side inlet temperature had the most significant effect on the heat transfer rate and thermal performance. With a 10.3% increase in the hot-side inlet temperature, the heat transfer rate increased by 89.0%, and the thermal performance decreased by 17.7%. The test sample effectiveness was most significantly affected by the cold-side inlet temperature, and it increased by 23.3% as the cold-side inlet temperature increased by 5.9%. The effectiveness increased to 0.96 with an increase in the cold-side inlet temperature to 339.1 K.
