Аннотация

Jet cooling is one of the effective and active methods for thermal control of electronic devices. The paper presents experimental data of the study of heat transfer during multi-jet cooling of a LED module at a power of 100 - 300 W. The influence of the coolant temperature at the inlet on the heat transfer enhancement is investigated. It is shown that with increasing power, the temperature inhomogeneity along the LED surface increases. A significant effect of the coolant inlet temperature on the heat transfer enhancement is shown. Water is used as a coolant. The surface temperature of the LED module is shown to be by 10 C lower for the coolant inlet temperature of 10 C in comparison with the coolant inlet temperature of 25 C at a LED power of 300 W.
