Heat exchanger having channels for damping liquid motions

Abstract

A heat exchanger for indirect heat transfer between a first medium and a second medium having a shell which has a shell space to accommodate a liquid phase of the first medium, and at least one heat-exchanger block having first heat-transfer passages to accommodate the first medium and second heat-transfer passages to accommodate the second medium, such that indirect heat can be transferred between the first medium and the second medium. The heat-exchanger block is arranged in the shell space so that it can be surrounded with a liquid phase of the first medium in the shell space. A plurality of cylindrical channels are provided in the shell space laterally to the heat-exchanger block and parallel to each other to conduct the liquid phase of the first medium.

 in that a plurality of cylindrical channels for conducting the liquid phase of the first medium that run parallel to one another are provided in the shell space laterally in relation to the at least one heat exchanger block. 
   
     
     
         2 . The heat exchanger as claimed in  claim 1 , characterized in that the channels are fixed to one another in such a way that they form an interlinked unit, which is in particular formed separately from the at least one heat exchanger block and/or the shell. 
     
     
         3 . The heat exchanger as claimed in  claim 1 , characterized in that the extent of the channels along the longitudinal axis of the respective channel is greater than the greatest inside diameter of the respective channel perpendicularly in relation to the respective longitudinal axis. 
     
     
         4 . The heat exchanger as claimed in  claim 3 , characterized in that—with respect to the longitudinal axes—the channels have the same length, or in that—with respect to the longitudinal axes—at least some channels have different lengths, in particular to adapt the unit to a curved region of an inner side of the shell. 
     
     
         5 . The heat exchanger as claimed in  claim 2 , characterized in that the respective channel is formed by a hollow profile, in particular the hollow profiles being connected to one another in such a way that the interlinked unit referred to is formed. 
     
     
         6 . The heat exchanger as claimed in  claim 1 , characterized in that the channels are formed by a plurality of interconnected plate-shaped elements, which are connected to one another. 
     
     
         7 . The heat exchanger as claimed in  claim 3 , characterized in that the longitudinal axes of the channels run parallel to the vertical. 
     
     
         8 . The beat exchanger as claimed in  claim 3 , characterized in that the longitudinal axes of the channels run parallel to the horizontal. 
     
     
         9 . The heat exchanger as claimed in  claim 8 , characterized in that at least some of the channels have a flow retarder or are closed. 
     
     
         10 . The heat exchanger as claimed in  claim 2 , characterized in that the unit has along the vertical a length that is at least greater than half the height of the at least one heat exchanger block along the vertical, preferably greater than or equal to the height of the at least one heat exchanger block along the vertical. 
     
     
         11 . The heat exchanger as claimed in  claim 2 , characterized in that the unit is arranged between the at least one heat exchanger block and a neighboring portion of the shell. 
     
     
         12 . The heat exchanger as claimed in  claim 1 , characterized in that the heat exchanger has a further heat exchanger block, which is arranged in the shell space and along the horizontal is arranged next to the one heat exchanger block 
     
     
         13 . The heat exchanger as claimed in  claim 2 , characterized in that the unit is arranged between the two heat exchanger blocks. 
     
     
         14 . The beat exchanger as claimed in  claim 2 , characterized in that the heat exchanger has a plurality of units which respectively have a plurality of cylindrical channels for conducting the liquid phase of the first medium that run parallel to one another, in particular the respective unit being arranged between one of the heat exchanger blocks and a neighboring portion of the shell or between two heat exchanger blocks.
