ABSTRACT:
A heat transfer apparatus comprises an evaporating chamber having arranged in the interior thereof essentially coaxially therewith a vaporizer fabricated from capillary material permeable to a heat transfer fluid and adapted to maintain a thermal contact with a heat source, and a condenser chamber. The vaporizer is provided with vapor release passages communicable with a vapor header, and a longitudinal axial passage communicable with each of two end cavities. Each of the end cavities is defined by the end surface of the vaporizer and the walls of the chamber. A zone of the condenser chamber containing the heat transfer fluid in a vapor phase communicates with the vapor header of the vaporizer by way of a first pipe, while the zone thereof containing the heat transfer fluid in a liquid phase communicates by way of a second pipe with the evaporating chamber. The vapor release passages are defined by longitudinal recesses and a multiplicity of annular recesses intersecting with the longitudinal recesses, the recesses being arranged on the outer surface of the vaporizer between annular projections thereof and intended to prevent vapor passing from the vapor release passages to the end cavities.
