Reversible cooling loop using magnetohydrodynamic pump for systems with variable heat distribution

Abstract

An apparatus comprises: electric circuits including a first circuit and a second circuit to operate in multiple modes including a first mode in which the first circuit dissipates more heat than the second circuit and in a second mode in which the second circuit dissipates more heat; and a coolant loop along which the first circuit and the second circuit are thermally coupled at spaced-apart locations, wherein the coolant loop includes a reversible magnetohydrodynamic (MHD) pump to pump a cold liquid metal through the coolant loop in reversible coolant-flow directions responsive to reversible current directions of a current applied to the MHD pump, such that when the first mode is active, the cold liquid metal initially encounters the first circuit and then encounters the second circuit, and when the second mode is active, the cold liquid metal initially encounters the second circuit and then encounters the first circuit.
