Abstract
Disclosed is a cryogenic fluid circulation pump that is capable of preventing heat from permeating into a cryogenic fluid by convection during the circulation of the cryogenic fluid by the pump and, at the same time, minimizing the transfer of heat to the cryogenic fluid circulating through a shaft rotating to rotate the pump. The cryogenic fluid circulation pump includes a magnet pump unit mounted in a vacuum chamber having an introduction channel and a discharge channel formed therein to prevent heat from permeating into the cryogenic fluid by convection for rotating by a magnetic force to circulate the cryogenic fluid, when a rotary force from a power source is transmitted to the magnet pump unit.
