Abstract
The spray cooling technology has great advantage in high heat flux removal. Because the heat transfer of spray cooling has much to do with the heater surface temperature, it is important to ensure that the entire heating surface temperature is in an effective operating range. Otherwise, excessive local temperature may threaten the normal operation of spray cooling. In this paper, experimental method was used to investigate the effect of installation angle of spray cooling on the heat transfer performance. The five installation angles tested in this study were 0°, 45°, 90°, 135° and 180°. Other experimental parameters remain constant, such as the flow rate, the spray height and the spray pressure. The results show the heat flux as a function of surface temperature with various installation angles in a graphical format.
