The invention relates to a heat exchanger block having a row of heat exchanger walls ( ) which are arranged at a distance from one another and define intervening heat-exchange medium flow chambers ( ) for a first and a second heat-exchange medium, and a plurality of spaced thermally conductive rods ( ) which extend all the way through the row of heat exchanger walls ( ) and the intervening heat-exchange medium flow chambers ( ). The heat exchanger walls are formed by flat-tube sections ( ) which are arranged at a distance from one another in the direction of the row and the interiors ( ) of which form first heat-exchange medium flow chambers, and the flat-tube interspaces ( ) of which form second heat-exchange medium flow chambers.

A method for controlling a motor vehicle air conditioning system is described. The motor vehicle air conditioning system comprises a refrigeration circuit including a refrigerant compressor, a condenser, an evaporator and a throttle device arranged upstream of the evaporator. The condenser is associated with a ventilating fan and the evaporator is associated with a blower. The compressor capacity, the condenser capacity and the evaporator capacity are directly or indirectly sensed by sensor means and supplied as electrical variables to an electronic control circuit which logically combines these input signals and generates output signals in dependence on at least two of these capacity values and including further parameters. The control circuit acts on electrically controllable acturators for influencing the compressor capacity, the condenser capacity and/or the evaporator capacity.

A heat exchanger is described that is constructed of several flat tubes arranged in parallel and at a distance to one another which, at their two front sides, are each closed off tightly. The end areas of the tubes are provided with connecting openings extending transversely to their longitudinal axis and leading to the adjacent flat tube or to the adjacent group of tubes. An advantage of the invention is its ease of manufacture.

An arrangement is disclosed for joining the tubes of a heat exchanger core to a connecting box, wherein the tubes are fastened to the connecting box and sealed, said tubes being secured to the connecting box by means of a friction joint and at least one space being provided for each tube surrounding the end of the tube; each said space comprising a cavity bounded by the connecting box and the tube or a corresponding recess, and being filled and sealed with adhesive material.

Disclosed is an evaporator comprising a connector member, a Venturi distributor connected to the connector member for receiving and distributing a coolant, wherein the Venturi distributor divides the coolant into a plurality of streams, a plurality of channels formed in the connector member for conducting the coolant streams from the Venturi distributor, the channels corresponding in number to the streams with each channel being positioned to receive one of the streams from the Venturi distributor, a plurality of evaporator pipes connected to the connector member in parallel flow arrangement, the pipes corresponding in number to the channels with each pipe being connected to one of the channels, thereby forming a continuous coolant flow path from the Venturi distributor via the channels to the evaporator pipes, and a collection chamber formed in the connector member for receiving the coolant from the pipes. Also disclosed is the use of the evaporator in air conditioners, particularly those of automotive vehicles.
