Abstract :
The theme of this paper is an investigation of the hydrodynamic performance of liquid pumps for electronics cooling applications, considered in conjunction with a range of primary heat exchangers. Pressure-flow characteristics of a set of geometrically- similar, miniature-scale centrifugal pumps are measured, and reductions in hydrodynamic efficiency are seen to occur below a critical Reynolds number. Six primary heat exchangers are characterised in terms of thermal resistance, pressure drop and hydrodynamic power consumption. Thermal resistance is formulated as a function of power consumption in order to facilitate the optimisation of a primary heat exchanger and pump combination for optimum energy efficiency.
