Abstract

The heat transfer from the surface of high-temperature superconductors to liquid nitrogen is studied. The effect of the heat flux density and heat-release surface orientation in the gravitational field on heat exchange characteristics is studied. It is shown that the heat transfer coefficient in the region of developed bubble boiling on a double-side cooled tape has a minimum at tilt angles close to 45°. The relations describing the dependence of the heat transfer coefficient on the heat-release surface orientation are derived.
