Abstract
A liquid cooling system contained completely on a circuit board assembly. The liquid cooling system uses microchannels etched within the circuit board, those microchannels being filled with electrically conductive fluid that is pumped by a non-mechanical, magnetic pump. The pump can be separate from the device on the circuit board which is to be cooled or it can be integrated with the device that is to be cooled. In the latter circumstance, the same current which flows through the electronic device is the current which generates the Lorentz force that pumps the electrically conductive fluid through the microchannel.
