Description

The present invention relates to an evaporator / condenser arrangement according to the preamble of claim 1.

A generic evaporator / condenser arrangement is, for example, from WO 2015/076927 A1 famous. Such evaporator / condenser arrangements are used, for example, for cooling or cooling / heating, in particular as heat pumps in electric vehicles.

Such evaporator / condenser arrangements usually have two separate circuits for the passage of a cooling medium and a cooling medium as well as several lamellar layers for air to flow through.

The disadvantage of the evaporator / condenser arrangements known from the prior art is the relatively large structure of such arrangements. So are from the WO 2015/076927 A1 known heat exchangers, the flat tubes for the passage of the refrigerant are arranged separately from the flat pipes for the passage of the coolant one behind the other.

The object of the present invention is to provide an evaporator / condenser arrangement with a compact design.

This object is achieved by an evaporator / condenser arrangement having the features of claim 1.

The evaporator / condenser arrangement according to the invention has at least a first flat tube for the passage of a first medium and a second flat pipe for the passage of a second medium. A lamellar layer for a third medium to flow through is arranged between the flat tubes.

An inlet for the supply and an outlet for the removal of the first medium are connected to the at least one first flat tube.

Correspondingly, at least one inlet for the supply and one outlet for the removal of the second medium are connected to the at least one second flat tube.

The lamellar layer serving to control the temperature of the first flat tube and the second flat tube is arranged between a first flat tube serving to convey the first medium and a second flat tube serving to convey the second medium.

The flat tubes are formed in a connection area to the inlet and / or outlet from a plane aligned between the lamellar layers parallel to the contact surface of the lamellar layers and twisted into a plane perpendicular to this plane.

The arrangement of the at least one first flat tube and the at least one second flat tube and a lamellar layer arranged between these now ensure a compact design of such an evaporator / condenser arrangement with still good performance of such an evaporator / condenser arrangement.

The twisted design of the flat tubes enables a simple connection to the inlet or outlet for the respective flat tube.

Advantageous variant embodiments of the invention are the subject of the subclaims.

According to an advantageous development, a block of first and second flat tubes stacked one on top of the other with lamellar layers in between is stacked in such a way that a first or second flat tube follows a lamellar layer and a lamellar layer follows a flat tube, with first and second flat tubes alternating between the lamellar layers.

According to a further preferred embodiment variant, at least two first or second flat tubes are arranged one behind the other in the direction of flow of the third medium in a plane of the block.

This enables a further increase in throughput capacity.

According to an alternative embodiment variant, first or second flat tubes arranged in a plane of the block are connected to one another in an area outside the block to form a meander.

This makes it possible to arrange the inlet and outlet of the flat tube in question on the same side of the block.

According to a further advantageous embodiment variant, the inlets and outlets are tubular, in particular cylindrical tubular.

According to a further preferred embodiment variant, the flat tubes are connected to the inlets and outlets in such a way that a large diameter of the flat tubes is aligned parallel to the longitudinal axis of the inlets and outlets.

This enables the inlets and outlets, which are preferably tubular or cylindrical tubular, to be designed with a relatively small diameter.

According to a further advantageous embodiment variant, several first or second flat tubes are connected to a single inlet or outlet.
