Abstract

Abstract Methods and apparatus for transporting a heat-generating load through an environment affected by vibrations and pressure variations, employ a capillary structure for advancing that working fluid, when in a liquid state, from a condenser section at a heat-conducting supporting structure spaced from the load to an evaporator section at a heat-conducting load support at the load, for converting the advanced fluid to a vapor state with heat drawn from the load in the evaporator section. There is provided between the supporting structure and the load support a flexible enclosure encompassing around the capillary structure at least part of a space extending from the evaporator section back to the condenser section for returning the working fluid, when in its vapor state, in a heat-transfer cycle to the condenser section for reconversion to its liquid state upon removal of heat through the supporting structure and for reapplication of the working fluid in its liquid state through said capillary structure from the condenser section to the evaporator section for reevaporation thereat with more heat drawn from the load. Resilient means extended between the supporting structure and the load support are provided for effecting vibration damping of the load while removing heat therefrom in the evaporator section with the working fluid converting to its vapor state inside the flexible enclosure and the heat-transfer cycle in the flexible enclosure is protected against pressure variations occurring externally of that flexible enclosure.
