ABSTRACT:
This invention is directed to transferring heat from an extremely high temperature source to an electrically isolated lower temperature receiver. The invention is particularly concerned with supplying thermal power to a thermionic converter from a nuclear reactor with electric isolation.
Heat from a high temperature heat pipe (10) is transferred through a vacuum or a gap filled with electrically nonconducting gas (26) to a cooler heat pipe (18). The heat pipe (10) is used to cool the nuclear reactor while the heat pipe (18) is connected thermally and electrically to a thermionic converter (22).
If the receiver requires greater thermal power density, geometries are used with larger heat pipe areas for transmitting and receiving energy than the area for conducting the heat to the thermionic converter. In this way the heat pipe capability for increasing thermal power densities compensates for the comparatively low thermal power densities through the electrically non-conducting gap between the two heat pipes.
