Fig. 1(a) shows a traditional microchannel heat sink which contains a single inlet, a bank of microchannels spanning the entire device length, and a single outlet; Fig. 1(b) shows a manifold microchannel heat sink design where the heated area is discretized into an array of multiple heat sinks, each with separate inlets and outlets fed in parallel.
We report an experimental investigation of a novel, high performance ultrathin manifold microchannel heat sink. The heat sink consists of impinging liquid slot-jets on a structured surface fed with liquid coolant by an overlying two-dimensional manifold.
Enhanced Design of Cross-Flow Microchannel Heat Exchanger Module for High-Performance Aircraft Gas. of the module design and the versatility of the analytical tools at designing complex heat exchangers for high-performance aircraft gas turbine engines. Issue Section: Heat. Manifold Microchannel Heat Sinks: Isothermal Analysis,”.
One of the earliest works on manifold-microchannel heat sinks for electronics cooling was reported by Harpole and Eninger in 1991. Following this work, Copeland et al. developed a silicon-base manifold-microchannel heat sink that used fluorocarbon (FX3250) as the heat exchanging medium. Since then, many studies have been reported in the literature that investigate the physics of the flow.

Numerical analysis of manifold microchannel (MMC) heat sinks are performed. The MMC differs from a traditional microchannel heat sink where the flow length is greatly reduced to a small fraction.
A manifold microchannel heat sink integrated with a high efficient copper heat spreader is presented. A series analysis of three-dimensional fluid flow and heat transfer performance in this mirochannel heat sink and conventional structure are performed by CFX commercial software package. The temperature difference along the flow direction in the new microchannel heat sink is less than that of.

Based on the analysis of the different cross-sectional stacked microchannel heat sink behaviour the following conclusions can be drawn From the results during the process of simulation it was observed that the base temperature of the heat sink is having a minimum temperature of 250 C to maximum of 68.390 C for rectangular microchannel heat sink when compared to other cross-sectional heat sinks.
Performance analysis of double-layer microchannel heat sinks was performed under non-uniform heating conditions having randomly distributed hotspots. Two parallel-channel (parallel-flow and counter-flow) and one cross-channel (transverse-flow) designs of double-layer heat sink were evaluated with three sets of heating schemes. Each set of heating scheme consisted of eleven randomly distributed.

It is crucial to control the temperature of solar cells for enhancing efficiency with the increasing power intensity of multiple photovoltaic systems. In order to improve the heat transfer efficiency, a microchannel heat sink (MCHS) with V-ribs using a water-based nanofluid as a coolant for micro solar cells was designed. Numerical simulations were carried out to investigate the flows and heat.
