Abstract

A cooling system with a heat exchanger, which is designed or configured for through-flow of a coolant and a fluid to be cooled, a fluid line, which is designed or configured for through-flow of fluid emerging from the heat exchanger, and a conveying device, which is designed or configured to convey the fluid through the heat exchanger and the fluid line. A control device is designed or configured to control the conveying device in such a manner that the fluid flows through the heat exchanger and the fluid line in the same direction when the cooling system is in a normal mode and when in a de-icing mode. In addition, there is a water separator disposed in the fluid line.

First claim

1 . A cooling system, comprising:
a heat exchanger for through-flow of a coolant and a fluid to be cooled; a fluid line for through-flow of fluid emerging from the heat exchanger; a conveying device to convey the fluid through the heat exchanger and the fluid line; a control device to control the conveying device such that the fluid flows through the heat exchanger and the fluid line in the same direction when the cooling system is in a normal mode and when in a de-icing mode; and a water separator disposed in the fluid line.

2 . The cooling system according to claim 1 , wherein the control device is configured to control the conveying device such that the fluid flows through the fluid line in the direction of gravity when the cooling system is in the normal mode and when in the de-icing mode.

3 . The cooling system according to claim 1 , wherein the fluid line comprises a fluid outlet opening for removing the fluid from the fluid line.

4 . The cooling system according to claim 3 , wherein the fluid outlet opening is disposed in a downstream end region of the fluid line.

5 . The cooling system according to claim 3 , wherein the fluid outlet opening is disposed in a first side wall of the fluid line.

6 . The cooling system according to claim 1 , wherein the water separator comprises a water separating grating, disposed in the fluid line and extending over at least a portion of a cross-section of the fluid line through which flow can be effected, the water separating grating comprising a plurality of openings, the number and size of which are selected such that drops of water contained in the fluid stream flowing through the fluid line are able to pass through the water separating grating, but a gaseous component of the fluid stream flowing through the fluid line is deflected, at least partially, at the water separating grating.

7 . The cooling system according to claim 6 , wherein the water separating grating is disposed in the fluid line such that the gaseous component of the fluid stream flowing through the fluid line is deflected at the water separating grating, at least partially, in the direction of the fluid outlet opening for removing the fluid from the fluid line.

8 . The cooling system according to claim 6 , wherein the water separating grating is disposed in the fluid line such that it is aligned at an angle of approximately 30 to 60°, in particular at an angle of approximately 40 to 50°, and particularly preferably at an angle of approximately 45°, in relation to the direction of flow of the fluid stream flowing through the fluid line.

9 . The cooling system according to claim 6 , wherein the water separating grating comprises a curved contour and extending, in a concavely curved manner, from a second side wall of the fluid line that is opposite the first side wall of the fluid line, in the direction of the first side wall of the fluid line.

10 . The cooling system according to claim 6 , wherein the water separator comprises a flow deflecting device, which is configured to deflect the fluid stream, flowing through the fluid line, in the direction of a surface of the water separating grating.

11 . The cooling system according to claim 10 , wherein the flow deflecting device comprises a flow deflecting element, which extends from the first side wall of the fluid line in the direction of the surface of the water separating grating.

12 . The cooling system according to claim 1 , wherein the water separator comprises a catching device for catching drops of water settled on an inner face of the fluid line.

13 . The cooling system according to claim 12 , wherein the catching device comprises a catching element, which extends, along an inner circumference of the fluid line, from the inner circumference of the fluid line in the direction of an interior of the fluid line.

14 . The cooling system according to claim 13 , wherein the catching element is disposed in the fluid line such that drops of water caught by the catching element flow, by the action of gravity, in the direction of the water separating grating.

15 . The cooling system according to claim 13 , wherein the catching element is inclined, about an axis extending in the direction of the fluid flow through the fluid line, in the direction of the water separating grating, and additionally about an axis extending perpendicularly in relation to the direction of the fluid flow through the fluid line.

16 . The cooling system according to claim 1 , wherein the water separator comprises a collecting device, for collecting drops of water separated out from the fluid stream flowing through the fluid line, which is disposed in a downstream end region of the fluid line.

17 . A method for operating a cooling system, comprising:
routing a coolant and a fluid to be cooled through a heat exchanger; routing fluid, emerging from the heat exchanger, through a fluid line; conveying the fluid through the heat exchanger and the fluid line by a conveying device; controlling the conveying device such that the fluid flows through the heat exchanger and the fluid line in the same direction when the cooling system is in a normal mode and when in a de-icing mode; and separating drops of water, contained in the fluid stream flowing through the fluid line, out of the fluid stream by a water separator disposed in the fluid line.

18 . The method according to claim 17 , wherein the conveying device is controlled such that the fluid flows through the fluid line in the direction of gravity when the cooling system is in the normal mode and when in the de-icing mode.
