Abstract: A cooling attachment can be releasably fastened to a work machine, which has a shaft in which a rod-like tool is guided with a rotary or hammering action and exits the shaft at a free end. The cooling attachment has a housing that encloses the work machine and in particular the shaft thereof and the tool that exits it, the latter only partially. Formed within the housing is a first cooling channel for conducting a coolant from an inlet opening to the tool exiting the free end of the housing shaft.

Abstract: Disclosed herein is a novel stepped segmental baffle for an electric process heater. This baffle includes a plurality of stepped segments, wherein each of the stepped segments is a flat structure having a plurality of perforations through which elongated heating elements extend. The stepped segments are disposed orthogonally relative to the central axis and the stepped segments are spaced apart from each other by an axial distance. This baffle is easier to manufacture as a stepped segmental baffle than prior-art helical or spiral baffles. The stepped segmental baffle provides better performance of the electric process heater by increasing the heat transfer rate by forcing fluid flow over the heating elements. An electric process heater incorporating the stepped segmental baffles provides improved performance for the same heater size or provides the same performance in a smaller and more compact heater as compared to the prior art.
