  • Multi-tube heat exchanger and connectors therefor
    Patent number: 4832119
    Abstract: A heat exchanger particularly for solar water heating applications including a plurality of fluid conducting ducts separated by a plurality of webs which are spaced apart longitudinally to leave substantial regions of the ducts free of webs. The ducts are connected to supply and return manifolds via connectors, the connectors having recesses into which the ends of the ducts are inserted and retained when the connectors are inserted in apertures in the manifolds.

  • Solar water heating apparatus
    Patent number: 4606327
    Abstract: A clip is provided with first and second members to engage with opposing ends of a tile. The members are connected so as to be able to move relatively toward and away from each other so that detachable securement to the tile is possible. A constraint is provided to prevent substantial movement away from each other when attached to the tile.

  • Connection assemblies
    Patent number: 4597597
    Abstract: A connection assembly for connecting flexible tubes such as flexible tubes of a solar heat exchanger to a header pipe. The connection assembly includes a tubular spigot member which co-acts at one end with a sleeve to compress the tube and maintain the tube in sealing engagement with the spigot member. The opposite end of the spigot member is engaged with the header pipe by means of a hollow flexible plug which is located in an aperture in the header pipe and which expands radially outwardly on engagement with the spigot member to prevent withdrawal of the spigot member and ensure efficient sealing therearound.
