Abstract
Abstract A device for dissipating heat from a cylindrical object includes a heat dissipating element of thermally conductive material and at least a first spring for releasably and resiliently holding the heat dissipating element against the exterior of the object, in particular an automotive oil filter. In the disclosed examples, there are a plurality of like elongated heat dissipating elements each of which has a hole therethrough, and the spring is a coil spring which passes through the holes and its ends are fastened to each other. Each heat dissipating element has an inner flange providing the element with an inner face for fitting against the cylindrical object and a central portion projecting outwardly from a central location relative to the inner flange, and the spring-containing holes are located in the central portions of the heat dissipating elements. In one example, each heat dissipating element has substantially the shape of a T-bar and in another example, each heat dissipating element has substantially the shape of an I-beam. In combination with the object, the inner faces of the heat dissipating elements fit against the cylindrical object with the spring or springs under resilient tension and surrounding the cylindrical object.
