Abstract
A set of interchangeable adapters for coupling an evaporation head of a pipe freezer apparatus with pipes of different diameters is described. Each adapter includes a thermally conductive body having a first surface defining a first channel shaped and sized to securely and releasably receive the evaporation head. The body of each adapter also has at least one pipe-engaging surface defining a substantially semicircular pipe channel conforming to a selected standard pipe diameter. In a preferred embodiment, the set includes a plurality of adapter pairs, each adapter of a pair having pipe channels of the same radii as its mate and each pair having pipe channels of different radii than those of the other pairs. Thus, the set of interchangeable adapters is well suited for holding a pair of evaporation heads in thermal communication with pipes of several different diameters.
