Abstract
The microchannel cooling technique appears to be a viable solution to high heat rejection requirements of today’s high-power electronic devices. The thermal design of the small electronics cooling devices is a key issue that needs to be optimized in order to keep the system temperatures at certain levels. Thus the need of microchannel became vital. This present work investigates the experimental work conducted in a rectangular microchannel heat sink of hydraulic diameter of 0.763 mm for a flow rate of 24 to 42 kg/hr with water to study the flow maldistribution with a rectangular header of three inlet condition viz. side inlet, centre inlet and double inlet condition. The header plays a significant role in distributing the water in to the channels. The uniform distribution of water leads to uniform heat transfer in microchannels. From the experimental results carried with a rectangular header of three inlet condition arrangements, it was found that rectangular microchannel with double inlet condition gives better uniform flow distribution than to other inlet conditions.
