Abstract: A fluid/air heat exchanging device (2) has fluid-conducting outside collecting chambers (6, 10) having an inlet (8) or outlet (12) and being connected to one another via duct-shaped fluid guides (14) that control the temperature of a fluid flow by an air flow. The air flows in duct-shaped air guides separated from the fluid guides (14). A further collecting chamber (18; 20, 22) is inserted between outside collecting chambers (6, 10). The further collecting chamber (18; 20, 22) is arranged parallel to the outside collecting chambers (6, 10). All the fluid guides (14) are connected to the further collecting chamber and one of the outside collecting chambers (6, 10).
Abstract: A temperature control device has a flow line (15) for supplying a consumer, connected to the flow line (15), with a liquid medium at a predetermined temperature. A return line (17) is connected to the consumer for returning at least one part of the liquid medium from the consumer to a mixing device (41). In a predefinable ratio, the liquid medium of the return line (17) is mixed in the mixing device with a storage medium provided in a tank (25). The mixing device has a mixing chamber (41) arranged below the filling level of the tank (25) with the storage medium.
Abstract: A liquid-air cooling system (1) has at least one fan device (2) including at least one variable-speed fan motor (3) driving a fan impeller (4) to create a cooling power for a fluid (5) in a fluid cycle (6). To regulate the speed of the fan motor (3) by a control and/or regulation device (24), at least one actual value (Ta) downstream of a segmented heat exchanger (19) is compared to a predefined desired value (Tb). The control and/or regulation device (24) adjusts the cooling power according to the current power values of the respective machine unit (9).
Abstract: A cooling device for an electric energy supply (2) has at least one first heat-dissipating part (3). The power components (4) of the first heat-dissipating part are connected to the cooling device (1) in a thermally conductive manner. A fluid-conducting connection (5) conducts liquid coolant (6) from a pump (7) to a cooler (8) over the first heat-dissipating part (3). One shut-off unit (9?, 9) each is arranged in the fluid-conducting connection (5) at least between the first heat-dissipating part (3) and the cooler (8) and between the pump (7) and the first heat-dissipating part (3). To avoid an overpressure in at least one part (3, 14) to be cooled, at least one pressure-limiting valve (17, 28) is provided.
Abstract: A heat exchanger, in particular for fluid cooling devices, has a package of plane-parallel plates (1) with flow regions (3, 5) for a hot medium and for a cooling medium alternatively between pairs of plates (1) lying on top of one another. Each region is laterally bordered by profile strips (7, 11) keeping the plates (1) at a distance and forming solder surfaces (25) adjoining the plates (1). The profile strips (7, 11) on the flow regions (3, 5) extend along edges of the plates (1) and abut one another at an angle. The profile strips (11) of the flow regions (5) of the cooling medium having a base body (13), two legs (17) extending from the base body along the solder surfaces (25), and a recess (15) between the legs open toward the adjacent flow region (5). The recess (15) at least in the region adjacent to its inner end segment (23) is bordered by planar wall parts (29).
