Heat exchanger tube supports

Claim 1

In a heat exchanger a number of heat exchange tubes having a tube support comprising: a plurality of strips, each of said strips having a plurality of equidistant first contact locations in one plane, a plurality of first portions extending in a given direction away from said plane from an adjacent first contact location to one of a plurality of second contact locations, a plurality of second portions, each extending in another direction from an adjacent second contact location and toward said one plane to one of a plurality of third contact locations, a plurality of third portions, each extending in said direction from an adjacent third contact location to one of a plurality of fourth contact locations; a plurality of fourth portions, each extending from an adjacent fourth contact location in said other direction and toward said plane to one of a plurality of fifth contact locations, a plurality of fifth portions each extending from one of said fifth contact locations in said direction and away from said plane to one of a plurality of sixth contact locations, a plurality of sixth portions each extending away from an adjacent sixth contact location in said other direction to another of said first locations, said fourth contact locations lying equidistant along another plane and joined to the first locations of an adjacent strip; the second contact location engaging over the width of the surface of said strip the surface of a tube extending through said other plane; the third and fifth contact locations engaging over the width of the surface of said strip a tube extending through said one plane and the sixth contact location engaging over the width of the surface of said strip the surface of another tube extending through the other plane.
