✦ Synopsis

Heat transfer characteristics of a copper plate (18 mm x 76 mm) to liquid helium have been measured by changing the heat surface orientation and the channel width of liquid helium. We observed that the critical heat flux depends on the heat surface orientation, and the critical heat flux has the maximum at the angle of 15 Β° -30 Β°, where the angle is taken from the horizontal axis. On the other hand, the minimum heat flux has less dependence on the heat surface orientation. The channel tends to degrade the heat transfer characteristics compared with the open surface at all surface orientations, especially at 0 Β°.

Heat transfer characteristics of a copper plate (18 mm x 76 mm) to liquid helium have been measured by changing the orientation and treatment of the heat transfer surface. The treated heat transfer surfaces were (a) the polished Cu surface, (b) the oxidized Cu surface and (cl, (d) the Cu surface oxi
