Abstract

The main purpose of this study is focused on experimental investigation of cooling performance of various minichannel designs. The hydraulic dimension of one of the heat sink is 3 mm while that of the other is 2 mm. Deionised water was used as the coolant for studies conducted in both the heat sinks. Tests were done for a wide range of flow rates (0.7 l–9 l h−1) and heat inputs (5–40 kW/m2). Irrespective of the hydraulic diameter and the geometric configuration, profits and boundaries of each channel shape are analyzed and discussed in the clarity of experimental data. The total thermal resistance and the average heat transfer coefficient are compared for the various channels inspected.
