Abstract

A control cabinet cooling device ( 1 ) includes a housing ( 2 ) which comprises a hot air inlet ( 3 ) and a cooling air outlet ( 4 ), wherein the air to be cooled is suctioned by means of at least one fan ( 5 ) in the housing ( 2 ) via the hot air inlet ( 3 ) into the housing ( 2 ), led through an air-refrigerant heat exchanger ( 6 ) in the housing ( 2 ) and blown out as cooled air via the cooling air outlet ( 4 ), wherein a droplet separator ( 7 ) is arranged downstream of the air-refrigerant heat exchanger ( 6 ) in the air flow direction through the housing ( 2 ), wherein at least one lower end ( 8 ) of the droplet separator ( 7 ) in vertical direction is enclosed by an encapsulation ( 9 ) which, on the side thereof facing the droplet separator ( 7 ), comprises a condensate collection reservoir ( 10 ), into which a condensate discharge ( 11 ) of the droplet separator ( 7 ) leads.

First claim

What is claimed:

1. A control cabinet cooling device with a housing which comprises a hot air inlet and a cooling air outlet, wherein the air to be cooled is suctioned by means of at least one fan in the housing via the hot air inlet into the housing, led through an air-refrigerant heat exchanger in the housing and blown out as cooled air via the cooling air outlet, wherein a droplet separator is arranged downstream of the air-refrigerant heat exchanger in the air flow direction through the housing, characterized in that at least one lower end of the droplet separator in vertical direction is enclosed by an encapsulation which, on the side thereof facing the droplet separator, comprises a condensate collection reservoir, into which a condensate discharge of the droplet separator leads, and wherein
the encapsulation covers half or more of the surface of two vertical side walls of the droplet separator, which face one another in parallel, and which in each case connect an air inlet side of the droplet separator to an air outlet side of the droplet separator.

2. The control cabinet cooling device according to claim 1 , in which the condensate discharge comprises a condensate line which leads into the condensate collection reservoir and out of the housing.

3. The control cabinet cooling device according to claim 1 , in which the encapsulation includes at least one lower front side of the droplet separator in vertical direction as well as a lower end of an air outlet side of the droplet separator.

4. The control cabinet cooling device according to claim 1 , in which the encapsulation is formed from a foamed thermal insulation material.

5. The control cabinet cooling device according to claim 1 , in which the encapsulation is formed from a plastic foam.

6. The control cabinet cooling device according to claim 1 , in which the air-refrigerant heat exchanger and the droplet separator are accommodated, spaced apart from one another or immediately adjoining one another, in the encapsulation, wherein an air inlet side of the air-refrigerant heat exchanger leads into an air inlet of the encapsulation, and an air outlet side of the droplet separator leads into an air outlet of the encapsulation.

7. The control cabinet cooling device according to claim 1 , in which an air inlet of the encapsulation is formed as a nozzle, and an air outlet of the encapsulation is formed as a diffuser.

8. The control cabinet cooling device according to claim 1 , in which the encapsulation has a modular structure, with at least one bottom tray in which the droplet separator is inserted via the lower front side thereof, and with at least one side panel which is connected via a plug-in connector to the bottom tray.

9. The control cabinet cooling device according to claim 8 , in which the side panel comprises several panel tiles which are connected to one another via a plug-in connector.

10. The control cabinet cooling device according to claim 8 , in which the side panel comprises several panel tiles which are connected to one another via a plug-in connector and bonded to one another.

11. The control cabinet cooling device according to claim 1 , in which the encapsulation has a modular structure, with at least one bottom tray in which the droplet separator is inserted via the lower front side thereof, and with at least one side panel which is connected via a plug-in connector to the bottom tray and bonded thereto.

12. The control cabinet cooling device according to claim 1 , in which the housing comprises a rack with a rectangular bottom group and a rectangular roof group each consisting of four horizontal struts, wherein the encapsulation is fixed via fastening recesses in the horizontal struts on the bottom group and/or on the roof group.

13. A control cabinet cooling device with a housing which comprises a hot air inlet and a cooling air outlet, wherein the air to be cooled is suctioned by means of at least one fan in the housing via the hot air inlet into the housing, led through an air-refrigerant heat exchanger in the housing and blown out as cooled air via the cooling air outlet, wherein a droplet separator is arranged downstream of the air-refrigerant heat exchanger in the air flow direction through the housing, characterized in that at least one lower end of the droplet separator in vertical direction is enclosed by an encapsulation which, on the side thereof facing the droplet separator, comprises a condensate collection reservoir, into which a condensate discharge of the droplet separator leads, wherein
the encapsulation has a modular structure, with at least one bottom tray in which the droplet separator is inserted via the lower front side thereof, and with at least one side panel which is connected via a plug-in connector to the bottom tray; and
the side panel comprises several panel tiles which are connected to one another via a plug-in connector.

14. A control cabinet cooling device with a housing which comprises a hot air inlet and a cooling air outlet, wherein the air to be cooled is suctioned by means of at least one fan in the housing via the hot air inlet into the housing, led through an air-refrigerant heat exchanger in the housing and blown out as cooled air via the cooling air outlet, wherein a droplet separator is arranged downstream of the air-refrigerant heat exchanger in the air flow direction through the housing, characterized in that at least one lower end of the droplet separator in vertical direction is enclosed by an encapsulation which, on the side thereof facing the droplet separator, comprises a condensate collection reservoir, into which a condensate discharge of the droplet separator leads; wherein
the encapsulation has a modular structure, with at least one bottom tray in which the droplet separator is inserted via the lower front side thereof, and with at least one side panel which is connected via a plug-in connector to the bottom tray; and
the side panel comprises several panel tiles which are connected to one another via a plug-in connector and bonded to one another.
