Abstract
A forced convection heat transfer apparatus wherein a large quantity of heat can be efficiently transferred even when a temperature difference is small, by transmitting power to a magnet, which is rotatable along a circulation flow path of a magnetic fluid, and obtaining a magnetic fluid circulation speed in proportion to the rotating speed.
Claims6
A heat transfer apparatus of a forced convection type comprising a heat receiving section, a heat discharging section, a fluid flow path for circulating a magnetic fluid between said heat receiving and said heat discharging sections, and a rotatable magnet unit disposed alongside at least a portion of said fluid flow path in said heat receiving section, wherein said rotatable magnet unit applies a varying magnetic force to said magnetic fluid in said portion of the fluid flow path in said heat receiving section, wherein said fluid flow path in said heat receiving section has different inner volumes between the upstream side and the downstream side of the rotating area of said magnet unit, and wherein the inner volume of said fluid flow path on said upstream side is greater than the inner volume of said fluid flow path on said downstream side.
