Abstract
For cooling the working face of mechanical working elements, such as bearings, rotary seals and friction devices, the cooling fluid flows through a passage which is located behind the working face and contains a porous thermally-conductive mass having interconnecting pores. The conductive material of the porous mass is in intimate thermal contact with the wall behind the working face and acts as a heat exchanger having an extended heat transfer surface. The porous mass preferably comprises a sintered highly-conductive material.
