Oct 01, 2020 For low heat power liquid metal heat transfer, especially in the heat dissipation field of electronic devices, direct-current electromagnetic pump DC-EMP is a suitable option for transporting coolant, which has a rather simple structure and small volume.
A small electromagnetic induction pump for liquid Ga was built to test this cooling method. The development of an induction electromagnetic pump is expected in that process because, in maintainability and durability, elec- tromagnetic induction pumps are superior to mechanical pumps and electromagnetic dc pumps.
The object of the invention is therefore firstly an electromagnetic pumping method suitable for liquid or molten metals having low electrical conductivity, consisting in using an electromagnetic pump comprising a pumping duct in which the liquid or molten metal flows, at least a section of the said duct being crossed simultaneously by an ...
May 19, 2005 Sapphire Turns To Liquid Metal Cooling. Sapphire is releasing its next generation of graphic card coolers based on. liquid metal which is even more efficient than water cooling. The liquid metal. will flow through the copper pipes circled with electromagnetic phenomenon to. cool down the card. Some early testing showed that prototype cooled Radeon.
Electromagnetic pumps are not noted for their efficiency - values on the order of 15 are not unusual. However, the Energy Systems Group of Rockwell International, under contract to the Department of Energy, has recently designed, built, and tested for the Clinch River
Aug 01, 2010 Compact, Lightweight Electromagnetic Pump for Liquid Metal Marshall Space Flight Center, Alabama A proposed direct-current electromagnetic pump for circulating a molten alkali metal alloy would be smaller and lighter and would demand less input power, relative to currently available pumps of this type.

A pump that operates on the principle that a force is exerted on a current-carrying conductor in a magnetic field. The high electrical conductivity of the liquid metals pumped liquid metals are used as the heat-transfer media in some nuclear reactors and magnetohydrodynamic systems allows a pumping force to be developed within the metals when they are confined in a duct or channel and ...
Electromagnetic pumps can be used to liquid metal fluid flow control in cooling circuits. The operation of electromagnetic pumps used to flow control is based on Lorentz force. This force can be achieved by magnetic field and electric current interaction, controlled by external independent power supplies.
