This paper reviews supercritical helium gas cooling methods. The thermal transport properties of supercritical helium near 4.2°K are collected.Cryogenic helium pump or bellow pump for forced supercritical circulation is adequate to the laboratory-scale cooling system.The superconducting composite configurations with hollow conductors are used for supercritical channel forced cooling.
