摘要: A multichannel flat tube for a heat exchanger has a plurality of parallel flow channels aligned in a row, side by side, along a transverse axis of the tube. At least the inner flow channels have oval cross-sections, and major semiaxes of the inner flow channels are inclined relative to the transverse axis of the tube at an acute angle. The flat tube can be designed for high operating pressures with relatively low weight and relatively high heat exchange capability. The construction may be used, for example, in CO2 air conditioners in motor vehicles.

摘要: An integrated modular collector—heat exchanger unit for motor vehicle air conditioners and the like has a collector housing in which a collecting space and a heat exchanger unit are disposed. The heat exchanger unit includes two separate heat exchanger ducts which are in a thermal contact. One heat exchanger duct has a helical course and is part of a first flow duct which extends from a housing inlet to a housing outlet in the collector housing. The other heat exchanger duct is part of a second flow duct extending between the collecting space and a housing connection. This other heat exchanger duct also has a helical course, its coils in each case being in a thermal contact with at least one adjoining coil of the first of the first heat exchanger duct.

摘要: The invention relates to a collector tube (1) for a heat transfer unit. The tube comprises one or several slits (3d) on the periphery thereof, whereby said slits are formed by a punch press without an inner die or by high-pressure shaping for inserting a respective flat tube. The invention also relates to a method for producing said collector tube (1). According to the invention, a collector tube (1) is provided with an outer radius (D/2) to tube wall thickness (s) ratio of less than 5. The slits (3d) are introduced preferably parallel to, or at an acute 2 angle to the longitudinal axis of the tube. The collection tube can be produced by bending a flat material and subsequently sealing the longitudinal slits arising from the bending process by soldering or welding. Said collector tube can be used, e.g. for gas coolers and evaporators for CO2 air conditioning systems in motor vehicles.

摘要: An air-conditioning system operated with CO2 for a vehicle has a high-pressure section that is connected to the output of a compressor and includes a gas cooler, a low-pressure section that is connected to the suction side of the compressor and includes an evaporator, and an expansion member connecting the high-pressure section and the low-pressure section. The expansion member has a fixed restrictor with a throttle opening of predetermined length and diameter connected between an inlet from the high-pressure section and an outlet to the low-pressure section whereby under all operating conditions of the system, a pressure of refrigerant in the high-pressure section of the system is limited to values of less than 14 MPa. The restrictor can be connected in parallel with a pressure limiting valve and can include two or more different throttle openings that can be selectively connected for refrigerant flow.

摘要: An optimized CO2 air-conditioning system for a vehicle has individual components designed and/or matched to one another in such a way that if the high pressures in the high-pressure section deviate by up to ±30% from the optimum high pressures, the associated optimum performance figures are reduced by no more than 20%. The individual components include a controllable compressor, a gas cooler, an internal heat exchanger, an evaporator and an accumulator. As a result, a fixed throttle expansion member can be used between the high-pressure and low-pressure sections of the system.
