Cooling Delta For A Dry Cooling System

Abstract

The invention is a cooling delta for cooling liquids, gases or vapours, said cooling delta comprising cooling panels arranged at an angle relative to one another, in which cooling panels cooling tubes are arranged, the cooling tubes extend horizontally or substantially horizontally, and the cooling delta further comprising a first media flow header being connected to the cooling tubes at a junction of the cooling panels, and providing a flow communication space for the cooling tubes, and second media flow headers being connected to opposite ends of the cooling panels with respect to the first media flow header, and providing a flow communication space for the cooling tubes.

1 . A cooling delta for cooling liquid, gaseous or steam media, said cooling delta comprising cooling panels arranged at an angle relative to one another, in which cooling panels cooling tubes are arranged, characterised in that
 the cooling tubes extend horizontally or substantially horizontally, and   the cooling delta further comprises   a first media flow header being connected to the cooling tubes at a junction of the cooling panels, and providing a flow communication space for the cooling tubes, and   second media flow headers being connected to respective opposite ends of the cooling panels with respect to the first media flow header, and providing a flow communication space for the cooling tubes.   
     
     
         2 . The cooling delta according to  claim 1 , characterised in that the first media flow header and/or the second media flow headers are formed as columns. 
     
     
         3 . The cooling delta according to  claim 1 , characterised by having a reinforcing steel structure comprising the first media flow header as an inside support column and the second media flow headers as outside support columns, and by comprising fixed and/or loose tube bundle sheets adapted for holding together the cooling tubes. 
     
     
         4 . The cooling delta according to  claim 3 , characterised in that the tube bundle sheet receiving the cooling tubes is formed in the support column, and the cooling tubes are welded or roll-pressed in the bores of the support columns. 
     
     
         5 . The cooling delta according to  claim 3 , characterised in that chambers adapted for media inlet and media outlet are connected to the cooling tubes extending through the bores or openings of the support columns supporting the cooling tubes, the chambers being disposed separately from the structures of the support columns. 
     
     
         6 . The cooling delta according to  claim 3 , characterised in that the cooling tubes are arranged in cooling columns, and the cooling tubes are held together in the cooling columns by one or more fixed or loose tube bundle sheets structurally separated from the support columns, and the cooling columns, thereby forming separate assembly units, are secured to the outside and inside support columns, and flexible sealing material is disposed between respective flat, bored surfaces formed on the support columns and the tube bundle sheets holding together the cooling tubes. 
     
     
         7 . The cooling delta according to  claim 6 , characterised in that the tube bundle sheets, seals of resilient material, bracing screws and optionally transition pieces are arranged at both ends of the cooling columns, and that the cooling tubes disposed in the cooling columns are removable together with the fixed and/or loose tube bundle sheets holding them together without dismantling the outside or inside support columns by displacing the cooling tubes in a direction perpendicular to the tubes. 
     
     
         8 . The cooling delta according to  claim 6 , characterised in that
 resilient rubber sealing rings are arranged between
 tube bundle sheets being arranged at both ends of the cooling columns, and being loose and—at least at one end of the cooling columns—fixed, 
 connecting screws, 
 transition pieces, and 
 sealing surfaces of the outside and inside support columns, and 
   the cooling column is displaceable either in the direction of the support column or in a direction opposite to that by removing
 a loose tube bundle sheet being arranged between the fixed tube bundle sheet and the flat surface of the support column, and 
 a transition piece being removable sideways after loosening the attachment screws, and 
   thus the cooling column is removable, without dismantling the outside and inside support columns, by displacing it first in a direction perpendicular to the cooling tubes at the side opposite the fixed tube bundle sheet and then at the side near the fixed tube bundle sheet.   
     
     
         9 . The cooling delta according to  claim 1 , characterised in that means adapted for draining the cooling delta are connected to the bottommost part of the inlet support column, and the cooling tubes are arranged ascending from the support column adapted for inletting the media towards the outlet support column. 
     
     
         10 . The cooling delta according to  claim 1 , characterised in that means adapted for draining the cooling delta are connected to the bottommost part of the inlet support column, and the cooling tubes ( 2 ) are arranged descending from the support column adapted for inletting the media towards the outlet support column, and the resistance of the cooling tubes ( 2 ) is chosen to be larger than the hydrostatic pressure difference resulting from the height difference between both ends of a cooling tube ( 2 ). 
     
     
         11 . The cooling delta according to  claim 1 , characterized in that a degassing means is connected to the uppermost part of the outlet support column.
