N2 - In present work, a parallel strip fin heat sink (PSFHS) with a Z-type inlet and outlet arrangement is proposed. Flow boiling experiments are conducted using R141b as the coolant at three different flow rates (75, 100 and 125 ml/min). Flow boiling heat transfer performance, including flow patterns, boiling curves and heat transfer coefficient, is discussed in detail. The total pressure drop of the heat sink is also evaluated. Results show that the discontinuous fin structure and the Z-typed inlet and outlet layout have a significant influence on the performance of the heat sink. It is also found that as the flow rate increases, the heat sink gradually exhibits excellent heat transfer performance, including a uniform temperature distribution and high heat transfer coefficient. However, the improvement in heat transfer with increased flow rates comes at the cost of increased total pressure drop.
