  • Hydronic radiant heat distribution panel and system
    Patent number: 5454428
    Abstract: An extruded aluminum radiant heat transfer plate includes an integral elongated receptacle for holding and confining a plastic tubing. The aluminum radiant heat transfer plate is extruded to provide heat transfer side edges in the form of thin-walled fins running the length of the extrusion. Between the fins, the extrusion provides the elongated receptacle for the plastic tubing. The receptacle can take the form of a "C" (as it appears in cross section) that stands above the plane of the heat transfer fins. The receptacle, alternately, can take the form of a "U" (as it appears in cross section), the legs of which integrally connect to the fins.
