Abstract

Heat transfer enhancements available from expanding the cross section of a microchannel or microchannel system in flow boiling are presented, including recommendations appropriate for design and selection of expanding channel heat sinks. The principal relevant operating parameters of a boiling-channel heat sink are the attainable critical heat flux (CHF), which limits the practical heat flux permissible and the pressure drop across the channel, which may impose substantial pum** costs on the loop and is coupled to stability of flow in the channels.
