The invention relates to a condenser, in particular a condenser cooled by a coolant, said condenser consisting of at least one tube/fin block having several flat tubes, each flat tube having a plurality of flow channels that extend adjacent to one another in the tube transverse direction and define a refrigerant-side hydraulic diameter (Dh refrigerant). At least one respective intermediate element defining a coolant-side hydraulic diameter (Dh coolant) is arranged in the region of the flat tubes. The condenser is characterized in that the ratio of the two hydraulic diameters (Dh coolant) to (Dh refrigerant) is greater than (>) 1.3.

This application relates to a coolant condenser assembly for an air conditioning system for a motor vehicle. In a supercooling region, at least two cooling pipes, as the first supercooling parallel section, are acted upon in parallel by the coolant in a fluid-conducting manner, the coolant which flows out of the first supercooling parallel section flows into a first supercooling intermediate flow duct, and the first supercooling intermediate flow duct opens into at least two cooling pipes as the second supercooling parallel section, and the second supercooling parallel section opens into a second supercooling intermediate flow duct and the second supercooling intermediate flow duct opens into at least two cooling pipes as the third supercooling parallel section, such that the outlet opening is disposed on a second longitudinal side of the coolant condenser assembly.

A vaporizer for a cooling circuit, particularly for a motor vehicle, is provided that includes a vaporization region, wherein a coolant flowing through the vaporization region takes up heat from an outside region, wherein the vaporization region is downstream of a first expansion element on the inlet side in the direction of flow of the coolant, wherein an exchanger member is provided between the vaporization region and the first expansion element, and wherein heat can be transferred from the coolant upstream of the vaporization region to the coolant downstream of the vaporization region.

A heat exchanger is provided, particularly for a heating or air conditioning system for motor vehicles, comprising at least one inlet channel and at least one outlet channel and at least one collector, which has at least two metal sheets or plates abutting each other, and a flow device, through which a first medium can flow, while a second medium can flow around said flow device. The first medium is distributed by an inlet channel to the collector and to the flow device and can be conducted to an outlet channel, whereby at least one further channel for distributing the coolant is provided, which is connected in a communicating manner via at least one opening to the inlet channel.

The invention relates to a heat exchanger, particularly a radiator for a heating or air conditioning unit in motor vehicles, which cools a coolant. Said heat exchanger (1) is penetrated by air, comprises collector pipes (S1, S2, S2, S4) and several essentially horizontally disposed pipes (5), and is divided into several partial blocks (T1, T2, T3, T4). The surfaces of the inventive partial blocks are selected according to the dimensions of structural space-related zones having different air temperatures inside the assembly space of the heat exchanger, the partial block which is first penetrated by the coolant being arranged within a structural space-related zone having a higher air temperature, preferably within the zone having the highest air temperature.

The invention relates to a heat exchanger, in particular, an evaporator (1), in particular for a motor vehicle air-conditioner, with a number of closely arranged refrigerant tubes and at least one cold reservoir (4), in which a refrigerant medium is provided. The evaporator (1) comprises two parallel regions (1′ and 1″) running across the total width, the first region (1′) corresponding to a conventional evaporator in design, the cold reservoir (4) being arranged in a separate second region (1″), through which at least a partial flow of refrigerant can flow which also flows through at least a part of the first region (1′) and the first and the second region are connected to each other by at least one overflow opening (13).

The invention related to a flat tube (1) comprising a return bend section (3), inside of which the flat tube (1) is bent back in such a manner that both planar tube sections (2a, 2b) thereof, which are connect to the return bend section, extend in a longitudinal direction with opposite flow-through directions (4a, 4b) and with longitudinal axes (5a, 5b) that are offset with regard to one another at least in the transverse direction (y). The invention provides that the return bend section (3) is formed in such a manner that a main bending axis (A) extends parallel to the flat tube to be plane and at a predeterminable angle to the tube longitudinal extension, whereby the flat tube plane is determined by the longitudinal and width extension of the flat tube (1).
