air flow 10 the slurper section 3 is adjacent to the condenser section 1 and comprises slurper channels 8 being an extension of the water channels 6 of the condenser section 1 but being separated from the water channel 6 by spacer bars 13 in the slurper channel 8 slurper holes 7 are provided through which water from the air flow 10 can penetrate into the slurper channel 8 by applying an underpressure the slurper flow 9 in the slurper channel 8 containing separated water and air is oriented parallel to the coolant water flow 11 in the condenser section 1 fig2 shows a first embodiment of the capillary bridge according to the invention a plate 5 is arranged on either side of the air flow channel 4 to form a capillary bridge the plates 5 are mounted in close proximity to the internal surface of the air flow channel 4 in the slurper section 3 in the embodiment shown in fig2 the plates 5 are arranged parallel to the internal surface of the air flow channel 4 further the plates 5 are in direct contact with the ends of the air fins 2 of the condenser section 1 the distance between the plates 5 and the surface of the slurper section.
