The invention relates to a heat exchanger (), in particular for a motor vehicle. The heat exchanger () includes a plurality of tubular bodies () stacked onto one another along a stack direction (S), which in each case delimit a first fluid path () for being flowed through by a refrigerant (K). The individual tubular bodies () are arranged along the stack direction (S) spaced apart from one another, so that between intermediate spaces () formed between the tubular bodies () that are adjacent in the stack direction (S), each form a second fluid path () fluidically separated from the first fluid paths () for being flowed through by air. The individual tubular bodies () extend transversely, preferentially perpendicularly to the stack direction (S) along a longitudinal direction (L). On a, with respect to the longitudinal direction (L), first longitudinal end () of the tubular bodies () a vessel () which extends in the stack direction (S) and fluidically communicates with the tubular bodies () is arranged. At least one inlet/outlet connector () at least partially delimiting a connector interior () projects from the vessel () to the outside for introducing the refrigerant into a vessel interior () surrounded by the vessel (). The connector interior () opens into the vessel interior (), so that refrigerant can be introduced into the connector interior and via the same conducted on into the vessel interior. The heat exchanger () comprises at least one connecting line () that can be flowed through by the refrigerant, by means of which the connector interior () fluidically communicates with the vessel interior ().

Heat exchanger and motor vehicle

A heat exchanger that can be flowed through in the x-direction based on the heat exchanger, By way of this, a homogenous temperature distribution can be achieved.

Heat exchanger

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 (D). At least one respective intermediate element defining a coolant-side hydraulic diameter (D) is arranged in the region of the flat tubes. The condenser is characterized in that the ratio of the two hydraulic diameters (D) to (D) is greater than (&#x3e;) 1.3.

Condenser

The invention relates to a condenser of stacked-plate design, having a first flow duct for a refrigerant and having a second flow duct for a coolant.

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.

Coolant condenser assembly

In a coolant condenser assembly for a motor vehicle air conditioning system, comprising cooling pipes for conducting a coolant through, two collecting pipes for fluidically connecting the cooling pipes, a collecting container with an upper cover wall and a lower bottom wall and a side wall as well as with an inlet opening for conducting the coolant into the collecting container and an outlet opening for conducting the coolant out of the collecting container, with the result that through the inlet and outlet openings the collecting container is fluidically connected to the collecting pipe and/or the cooling pipes, the collecting container comprises an outlet chamber and a riser pipe, and the outlet opening opens into the outlet chamber, and the outlet chamber is connected to the riser pipe and a storage chamber for the coolant is formed within the collecting container and outside the outlet chamber and outside the riser pipe, the collecting container preferably has an inlet chamber and a downpipe, and the inlet opening opens into the inlet chamber and the inlet chamber is connected to the downpipe and the storage chamber is formed outside the inlet chamber and outside the downpipe, the cooling pipes have a superheating region for cooling the vaporous coolant, a condensation region for condensing the coolant and a supercooling region for cooling the liquid coolant, wherein the supercooling region is formed above the superheating region and above the condensation region, the intention is that little coolant will be present in flow spaces in the collecting container. This object is achieved in that the height of the storage chamber is greater than the distance between the lower floor wall and the inlet and/or outlet openings.

The invention relates to an insert for a collector of a condenser, having a main body with a sealing lip for abutment against the inner wall of the collector axially between the two flow transfer openings of the collector, having a filter element for the fluid to flow through, having a fluid diverting element, and having a fluid duct such that the fluid diverting element diverts the radially inflowing fluid stream into an axially flowing fluid stream, and the fluid duct conducts the diverted fluid flow to the filter.

The invention relates to a heat exchanger (), in particular, a gas cooler for a vehicle air-conditioning unit, comprising several flat tubes () arranged in two or more parallel rows, a collector tube (), with one or more longitudinal separating walls (), running along the longitudinal axis of the collector tube (), dividing the collector tube () into two or more collector channels, whereby the collector tube () is embodied from two metal sheets () and openings () are provided in at least one of the metal sheets (), for accommodating the ends of the flat tubes (). Each longitudinal separating wall () is provided with tongue-like projections (), arranged in grooves () in at least one of the metal sheets () and fixed on the outer side of the metal sheet ().

The invention relates to a condenser for an air-conditioning system, particularly for a motor vehicle, with vertically arranged tubes, through which a coolant can flow and which are connected to an upper and a lower horizontally arranged manifold whereby permitting the flow of coolant. The inventive condenser also comprises a collector parallelly arranged underneath the lower manifold and, via an inflow opening and an outflow opening, between which a separating device is placed, is connected to the manifold in a manner that permits the flow of coolant. The collector accommodates a filtering and/or drying device. The separating device has a suction device for, in essence, liquid coolant.
