Abstract: The invention relates to an air-conditioner having a heat exchanger, such as an evaporator, for example, with a reservoir for a cold storage medium.

Abstract: The invention relates to an air-conditioner for a motor vehicle having a refrigerant circuit through which a refrigerant flows. The circuit includes a heat exchanger (1) through which the refrigerant circulates. A second internal refrigerant circuit exists in the heat exchanger (1) and operates when the first refrigerant circuit is at a standstill.

Abstract: Disclosed is a condenser and especially a tube therefor which is particularly suited for use in condensers that operate at operating pressures of approximately 20 bar. The condenser is a flat-tube condenser having tubes of substantially flat cross section extending between header tubes and cooling fins supported on the flat surfaces of the tubes. The tubes have a substantially flat cross section and a plurality of flow channels disposed side by side. The flow channels are substantially circular and have a hydraulic diameter of from 1.10 mm to 1.30 mm. Tubes of flat cross section and circular flow channels disposed in series operate with a particular advantageous effect in serpentine condensers.

Abstract: The application discloses a collection vessel 1 for a condenser of an air-conditioning system, preferably for motor vehicles. The collection vessel 1 holds in its interior a drier that can be exchanged via an opening which can be closed by means of a releasable lid. The lid is designed as a piston-like, cylindrical stopper 3, and be sealed and guided in an axially displaceable manner in a corresponding hole in the collection vessel 1, 2. The stopper 3 is pressed outwardly against a securing ring 9 by the internal pressure (pi) in the vessel, which securing ring is fixed in an annular groove 10 in the collection vessel 2 and is secured against release by a blocking shoulder 8 on the stopper 3. Due to this measure, the lid 3 of the collection vessel 2 cannot be removed when pressure is prevailing inside the vessel. Only when the vessel is depressurized can the securing ring and therefore also the stopper 3 be removed, so that a drier cartridge can be exchanged.

Abstract: A cooling apparatus is disclosed which includes a housing and a plurality of chambers which are arranged therein, sealed tightly and filled with a storage medium. The chambers have a substantially flat cross section and are arranged in at least one group. Passages extend between the chambers. The chambers of a group are combined to form a block, and at least one passage is provided between each pair of adjacent chambers. Each of the passages is connected to distribution and collection chambers formed in the housing, in the area of the distribution and collection chambers, with at least one feed port and a return port.

Abstract: A conditioned air unit for use in a motor vehicle providing heating or cooling to a plurality of regions having relatively independent temperature setting. The structure provides compact, flexible and convenient temperature conditioning for each region.

Abstract: A collecting box of a heat transfer device has a lengthwise partition in a collecting box between two rows of flat tubes. The tubes are designed as multichannel tubes that are divided by at least one lengthwise separating rib positioned at the level of the at least one lengthwise partition into a number of channels that corresponds to the number of collecting chambers. The at least one lengthwise partition is provided with its edge facing the tube ends with recesses with the spacing of the multichannel tubes. The recesses fit over the separating ribs of the multichannel tubes in a shapewise and flush manner and are connected tightly with the outside contours of the tube ends. In preferred embodiments the parts are made of metal and brazed together.
