Abstract: In a micro heat exchanger for the transfer of high area-specific amounts of heat from a heat source to a heat transfer medium, including a heat transfer structure with an inlet- and an outlet duct structure between which a plurality of passages extend through the heat transfer structure, the inlet and outlet duct structures are arranged in alternating order in the heat transfer area in close proximity to the heat source, with the inlet and outlet duct structure and the passages interconnecting the inlet and outlet structures covering the whole heat transfer area directly adjacent the heat source.

Abstract: In a microstructure apparatus for heating and atomizing a fluid with an inner body received in an outer tube, circumferential microstructure passages are formed into the inner surface of the outer tube or the outer surface of the inner body so as to form a flow passage which is provided with an inlet connector and heating means are incorporated into the inner body for heating the fluid conducted through the microstructure flow passages under pressure, the microstructure fluid passages extending spirally around the inner body so as to proved for a relatively long microstructure fluid flow passage which is open at the axial end thereof for discharging the fluid heated pressurized therein through the open axial end.

Abstract: A device for foaming around a transparent pane for a motor vehicle roof, including a top tool having a top shaping structure mounted on a top carrier, and a bottom tool having a bottom shaping structure mounted on a bottom carrier. The shaping structures act as a boundary for the area to be peripherally foamed, and the top tool and the bottom tool are made adjustable relative to one another for inserting or removing the pane and the interchangeable bottom shaping structure. The top shaping structure is also interchangeable to enable matching of the peripheral foaming device to different size and shape panes to be peripherally foamed.
