    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: A flat tube for use in a heat exchanger includes a reversal bend section connected between parallel extending tube sections. The reversal bend section extends from a plane of the tube sections by a distance less than a width of the tube sections. The tube sections can be straight or serpentine. A plurality of the flat tubes can be stacked and connected to collector tubes to form a heat exchanger for use as an evaporator in a vehicle air conditioning system. Corrugated ribs are positioned between adjacent flat tubes for increased heat conduction.

    摘要: A heat exchanger block includes a plurality of block units, located one behind the other, each having a plurality of stacked tube units with tube ducts extending transverse to the block depth and height. The tube ducts are connected at ends to associated collector ducts extending in the block height direction. The tube units can be formed from a multichamber flat tube. At least one collector-duct connection is provided between adjacent block units to form a meandering flow path through the heat exchanger block. The heat exchanger block can be used as an evaporator in a motor vehicle air-conditioning system.
