This report summarizes analyses of the effects of heat conduction in a copper block on the heat flux to a coolant flowing axially in the block. Heat is assumed to be added through one side of the block corresponding to conditions that may arise in fusion reactors or particle accelerator targets. It is found that three dimensional analysis of the heat transport will be required to accurately describe the heat flux at the wall of the coolant channel. The effects of axial and azimuthal heat conduction in the copper block depend on the block width to channel diameter ratio and the BIOT number of the channel.
