Abstract
By virtue of their compatibility with conventional packaging schemes, channel flows are well suited for cooling planar, multi-chip arrays. For example, chips may be mounted on one (or more) walls of a rectangular channel, while cooling is provided by flow of a liquid through the channel. Alternatively, cooling may be provided by microchannels manufactured in the chip itself. This paper focuses primarily on hydrodynamic and thermal conditions associated with liquid flow through a rectangular channel for which one wall houses an array of chips. Both single-phase mixed and forced convection cooling are considered, as are the benefits to be derived from using extended surfaces for heat transfer enhancement. Existing results provide a useful knowledge base for cooling system design, and depending on the Reynolds number, single-phase channel flows may be used to dissipate chip heat fluxes over a range from approximately 2 to 100 W/cm2. Consideration is also given to flow conditions associated with microchannels and their applicability to electronic cooling.
