Abstract: A device for exchanging thermal energy with ambient air including a heat exchanger, a fan arranged downstream for conveying air flow through the heat exchanger, and an air supply unit with at least one air inlet opening and an air discharge unit with an air outlet opening for discharging the air flow out of the fan into the environment. The air inlet opening and the air outlet opening are arranged on the same side of the device. The air supply unit has a supply air channel feeding into the heat exchanger, which extends along an inlet surface of the heat exchanger and continuously tapers along the inlet surface, and the outflow cross-section, defining the outlet speed of the air flow, of the air outlet opening is smaller than the inflow cross-section, defining the inlet speed of the air flow, of the at least one air inlet opening.

Abstract: The invention relates to a device for exchanging thermal energy with ambient air, comprising at least one heat exchanger (12; 162, 164; 202) through which an air flow can flow and which is assigned an axial fan (16; 166, 168; 208) for conveying the air flow through the heat exchanger and an outflow housing (40; 170, 172; 210) receiving the air flow, wherein the outflow housing has an air outlet opening (46) for discharging the air flow into the environment.

Abstract: The invention relates to a device for exchanging thermal energy with ambient air, comprising a heat exchanger (14; 206; 254) through which an air flow can flow, at least one fan (20; 268) arranged downstream of the heat exchanger for conveying the air flow through the heat exchanger, and an air supply unit (24) with at least one air inlet opening (38) for supplying the air flow from the environment to the heat exchanger and an air discharge unit (26) with at least one air outlet opening (62) for discharging the air flow out of the at least one fan into the environment, wherein the at least one air inlet opening (38) and the at least one air outlet opening (62) are arranged on the same side of the device.

Abstract: A suction unit comprising a suction apparatus, a dirt collection container, a filter device, wherein the dirt collection container is connected in terms of flow via the filter device to the suction apparatus, and a cleaning device for the filter device, which cleaning device comprises an external-air valve device, and at least one guide duct for air, which at least one guide duct has a first port which is connected in terms of fluid action to the cleaning device for the provision of external air from the at least one guide duct, a second port for the coupling of exhaust air of the suction apparatus into the at least one guide duct, and a third port which is connected in terms of fluid action to the surroundings of the suction unit, wherein air from the surroundings is configured to flow into the at least one guide duct via the third port.

Abstract: A drying apparatus for motor vehicles is provided, which is movable in a treatment direction relative to the surface of a motor vehicle to be dried. The drying apparatus includes a plurality of nozzles suppliable with drying air, a nozzle support device, and a holding device holding the nozzle support device. The nozzle support device includes at least two nozzle supporting parts, each holding at least one nozzle, arranged side by side transversely to the treatment direction. The drying apparatus includes an adjusting device for transferring the nozzle supporting parts relative to one another between at least two relative positions in which the parts are oriented at different angles to one another. The relative positions include an angular position in which air flows exiting the nozzles have or form an apex region on the leading side with respect to the treatment direction. A vehicle wash installation is also provided.

Abstract: The invention relates to a vehicle wash facility, including a drying apparatus for drying a motor vehicle which is held to a holding device of the vehicle wash facility and includes a nozzle support device, at least one blower and a plurality of nozzles which are arranged at a distance relative to one another at the nozzle support device and which can be supplied with drying air by the at least one blower, wherein the nozzles are flat jet nozzles, each providing a flow of air that spreads out in a fan shape.
