Thermal radiation system for soil stabilizer

Claim 1

A thermal stabilizer assembly comprising an elongated heatconductive liquid convection casing adapted to be positioned upright in a body of matter with its upper portion projecting therefrom into the atmosphere, said casing containing fluid in which convection currents can be generated responsive to differences in temperature between the top and bottom portions of the casing, and a heat-transmitting assembly secured around the upper portion of said casing, said heat-transmitting assembly comprising a plurality of elongated heat-conductive fin elements disposed parallel and outwardly adjacent to the upper portion of the casing, means securing said fin elements to the casing, and means on the fin elements defining laterally closed air ducts leading from the bottom to the top ends of the fin elements, whereby convection atmospheric air currents may flow upwardly through said ducts and transfer heat from the upper portion of the casing to the atmosphere, wherein said fin elements are provided with lateral abutting portions held in abutting contact by said securing means, wherein said securing means comprises a plurality of heat-conductive clamping bands surrounding and clampingly engaging spaced portions of said fin elements, wherein said fin elements include metal tubes, wherein said fin elements comprise relatively large tubes disposed around and engaging the casing and relatively smaller tubes inside the large tubes and disposed against and engaging the inner wall portions of the large tubes, and wherein the lower ends of the smaller tubes are spaced above the lower ends of the large tubes.
