Abstract

A device for the exchange of heat between a first and a second medium with pairs of trays stacked one on top of the other in a stacking direction is provided, wherein a first flow chamber that can be flowed through by a first medium is provided between the two trays of at least one pair of trays or several pairs of trays and a second flow chamber that can be flowed through by a second medium is provided between two pairs of trays adjacent to one another, wherein the first flow chamber has first flow path with flow path sections that can be flowed through consecutively in opposite directions for the first medium, which are separated from one another by a division wall arranged between the at least two trays of the at least one pair of trays, and wherein the second flow chamber has a second flow path for the second medium.

First claim

What is claimed is:

1. A device for an exchange of heat between a first and a second medium, the device comprising
a plurality of pairs of trays stacked one on top of the other in a stacking direction;
a first flow chamber through which a first medium is flowable is provided between two trays of at least one pair of trays; and
a second flow chamber through which a second medium is flowable is provided between two pairs of trays adjacent to one another,
wherein the first flow chamber has a first flow path with flow path sections that are configured to be flowed through consecutively in opposite directions for the first medium, and which are separated from one another by a division wall arranged between the two trays of the at least one pair of trays, and
wherein the second flow chamber has a second flow path for the second medium,
wherein at least one surface of a tray of the at least one pair of trays is an etched, milled or embossed surface, the etched, milled or embossed surface defining the first flow path and/or at least a portion of the flow path sections,
wherein a medium outlet has a larger cross section than a medium inlet,
wherein the first flow path is composed of two separate channels running parallel, each separate channel having flow path sections that are configured to be flowed through consecutively in opposite directions, the two channels being separated from one another by a web, wherein all of the flow path sections of each separate channel of the first flow path, except for curved portions of the flow path sections, extend perpendicular to a longitudinal direction of the device,
wherein the web has at least one interruption, the at least one interruption comprised of an opening to permit an exchange of fluid between the two separate channels,
wherein the medium inlet connects to a start of the flow path sections via inlet paths that run perpendicular to the two parallel separate channels and the medium outlet connects to an end of the flow path sections via outlet paths that run perpendicular to the two parallel separate channels, wherein the inlet paths and the outlet paths extend parallel to the longitudinal direction of the device,
wherein, except for a position of the at least one interruption, the web extends continuously along the flow path sections and has a constant width from the medium inlet to the medium outlet, and
wherein the medium inlet and the medium outlet are arranged laterally at the tray center of the plurality of pairs of trays, the medium inlet and the medium outlet forming a center fixed bearing that fixes the plurality of pairs of trays, such that the plurality of pairs of trays have a center fixed bearing and loose ends extending therefrom.

2. The device according to claim 1 , wherein two opposite surfaces of the two trays of the at least one pair of trays are etched, milled or embossed surfaces, the etched, milled or embossed surfaces defining the first flow path and/or at least some of the flow path sections.

3. The device according to claim 1 , wherein a medium inlet and outlet are arranged at a same height in a cooler longitudinal direction.

4. The device according to claim 1 , wherein the first flow path has at least one element that is configured to produce an increased pressure loss and is configured as a nozzle, an orifice plate or a labyrinth.

5. The device according to claim 1 , wherein the plurality of pairs of trays is formed by three or more pairs of trays lying one on top of the other and connected to one another by an adhesive force, wherein two outer pairs of trays and at least one center pair of trays is provided.

6. The device according to claim 1 , wherein the inlet paths and the outlet paths are disposed in a same plane as the flow path sections of the two parallel separate channels.

7. The device according to claim 1 , wherein the web extends continuously along the flow path sections such that the web includes straight sections and curved sections and wherein the at least one interruption is provided as a single interruption in each straight section of the web.

8. The device according to claim 1 , wherein the medium inlet is provided on an opposing lateral side of the device as the medium outlet.
