Experimental Investigation of Heat Transfer Rates and Pressure Drops through Compact Heat Exchangers
Paper i proceeding, 2014

This paper presents pressure drops and heat transfer rates for compact heat exchangers, where the heat exchangers are angled 90°, 60°, 30° and 10° relative to the incoming airflow. The investigation is based on two heat exchangers with different thicknesses. The experiments were performed for five airflow rates and five coolant flow rates, where the inlet temperature of the coolant was defined to two temperatures; ambient temperature and 90°C. The investigation showed that the 30° angled heat exchanger resulted in the lowest pressure drop and at the same time achieved the highest heat transfer rate, for a specific mass airflow rate.
