F28D 1/00 - Heat-exchange apparatus having stationary conduit assemblies for one heat-exchange medium only, the media being in contact with different sides of the conduit wall, in which the other heat-exchange medium is a large body of fluid, e.g. domestic or motor car radiators
F25B 1/00 - Compression machines, plants or systems with non-reversible cycle
A system of spacecraft radiators comprising pre-formed thermal-transfer modules joined together by at least one solid-state welding process. Critical failure points are eliminated by forming the thermal-transfer modules as a single unitary piece, preferably by an extrusion process. The thermal-transfer modules allow the formation of larger radiator assemblies, which may comprise a wide range of sizes and physical geometries.
F24D 3/14 - Tube and panel arrangements for ceiling, wall, or underfloor heating incorporated in a ceiling, wall or floor
F28D 15/00 - Heat-exchange apparatus with the intermediate heat-transfer medium in closed tubes passing into or through the conduit walls
B64G 1/50 - Arrangements or adaptations of devices for control of environment or living conditions for temperature control
F28D 1/053 - Heat-exchange apparatus having stationary conduit assemblies for one heat-exchange medium only, the media being in contact with different sides of the conduit wall, in which the other heat-exchange medium is a large body of fluid, e.g. domestic or motor car radiators with the heat-exchange conduits immersed in the body of fluid with tubular conduits the conduits being straight
F28F 1/22 - Tubular elements or assemblies thereof with means for increasing heat-transfer area, e.g. with fins, with projections, with recesses the means being only outside the tubular element and extending longitudinally the means having portions engaging further tubular elements
F28F 1/20 - Tubular elements or assemblies thereof with means for increasing heat-transfer area, e.g. with fins, with projections, with recesses the means being only outside the tubular element and extending longitudinally the means being attachable to the element
F28D 21/00 - Heat-exchange apparatus not covered by any of the groups
A system designed to increase diver safety in high-risk environments containing one or more hazardous materials. The system comprises one or more retrofittable kits enabling the upgrading of contaminate- vulnerable materials of an existing dive helmet to provide full environment isolation for the diver. The system preferably utilizes fluoroelastomeric replacement materials and components to convert an open circuit dive system to a closed circuit dive system. Methods of system development are also disclosed.
