Information handling system including AC electromagnetic pump cooling apparatus

摘要

An information handling system (IHS) is provided which is cooled via an electromagnetic pump. The pump pushes a heat conducting liquid metal fluid in a heat conducting path away from a heat producing device such as a processor. The EM pump is driven by an AC electric current supplied to a transformer. The AC driven transformer supplies both a magnetic field and an electric current to the fluid in the pump. The system is configured such that the magnetic field and the electric current in the fluid are substantially orthogonal. Each time the AC electric current reverses polarity, the magnetic field and the electric current also each change polarity to force fluid out of the pump in the same direction during both the positive and negative going portions of the AC electric current cycle.
