Fluid cooled diaphragms for diaphragm compressors are provided which utilize a multi-layer diaphragm with an upper or gas contacting later, and a bottom or lower layer, which has cooling grooves through which cooling fluid is circulated to reduce the diaphragm temperature. Additionally the upper surface of the diaphragm may be subjected to high loading to indent the surface and produce grooves for gas escape passageways. The gas contacting and grooved layer can be joined over part of the entire surface, or the grooved layer not connected to the other layer. Two or more layers may be used as required.

Fluid cooled diaphragms for diaphragm compressors

Solar energy collector assembly including a solar energy collector in an enclosed space housing with bottom closure member secured by a snap-fit spring channel and low thermal conductivity mating projection therefor, a collector member securing means comprising a plurality of stiff low thermal conductivity wire retainers and top cover securing and sealing means comprising a seal and clamp engaging the top cover just inward of its periphery, to prevent intrusion of condensate in the enclosed space of the housing.

Solar energy collector assembly and sub-assemblies thereof

Improved solar collector sub-assemblies and combinations thereof includes corner-locking piece sub-assemblies, top glazing clamping member sub-assembly, collector plate mounting member sub-assembly and collector assembly mounting means, all adapted to facilitate assembly and installation of collectors in accordance with the present invention and to permit thermal expansion of components thereof.

Solar energy collector sub-assemblies and combinations thereof

The invention relates to solar collectors which transfer thermal energy from a collector to a point of use by means of a heat exchange fluid. An array of collectors may be provided having a modified system to facilitate convenient assembly into an array and to provide balanced fluid flow across the array. The outlet conduit sized to insure the steady flow of fluid and air thus preventing the accumulation of air to the outlet to block fluid flow.

Solar collector with modified plumbing and array thereof

An improved solar energy collector assembly with a multiple glazed outer face, a flat collector member and an insulated bottom and side enclosure is provided with significantly enhanced thermal efficiency due to the mounting of the heat collector member and one or more inner glazing or transparent sheets in a manner to minimize conductive heat losses from this part of the assembly to the remainder of the assembly.
