Plate Cooler for Fluids

Abstract

A plate cooler for fluids, in particular hydraulic oil, having a parallelepiped packet of spaced-apart plate elements ( 1 ), which include vertical fluid channels ( 2 ) and air channels ( 3 ) disposed between the fluid channels and which at their ends communicate with a distributor box ( 4 ) disposed at their upper boundary and with a collection box ( 4′ ) disposed at their lower boundary, wherein the distributor box ( 4 ) can be made to communicate with at least one feed line leading away, and the collection box ( 4′ ) can be made to communicate with at least one discharge line leading away, and both boxes ( 4, 4′ ) are each embodied as a hollow extruded profile section of aluminum having a horizontal fluid channel ( 5 ) and have guide grooves ( 6 ), open toward the outside and T-shaped in cross section, for attaching connecting elements, and wherein the distributor box ( 4 ) and the collection box ( 4′ ) are closed off on both ends and have at least one upward- and downward-pointing horizontal opening ( 7 ) each, at which a respective connecting element, in the form of a closing plate ( 16 ) or an adapter piece ( 8; 19 ), is attachable to a horizontal opening ( 9 ) aligned with the horizontal opening ( 7 ) of the box ( 4, 4′ ) and to a connecting opening ( 11 ) for the feed line and discharge line that lead away and is fastenable to the guide grooves ( 6 ) of the box ( 4, 4′ ).

1 . A plate cooler for fluids, in particular hydraulic oil, having a parallelepiped packet of spaced-apart plate elements, which include vertical fluid channels and air channels disposed between the fluid channels and which at their ends communicate with a distributor box disposed at their upper boundary and with a collection box disposed at their lower boundary, wherein the distributor box can be made to communicate with at least one feed line leading away, and the collection box can be made to communicate with at least one discharge line leading away, and both boxes are each embodied as a hollow extruded profile section of aluminum having a horizontal fluid channel and have guide grooves, open toward the outside and T-shaped in cross section, for attaching connecting elements, and wherein the distributor box and the collection box are closed off on both ends and have at least one upward- and downward-pointing horizontal opening each, at which a respective connecting element, in the form of a closing plate or an adapter piece, is attachable to a horizontal opening aligned with the horizontal opening of the box and to a connecting opening for the feed line and discharge line that lead away and is fastenable to the guide grooves of the box. 
     
     
         2 . The plate cooler as defined by  claim 1 , characterized in that wherein the connecting opening of the adapter piece is disposed vertically. 
     
     
         3 . The plate cooler as defined by  claim 1 , wherein the guide grooves extend over the entire length of the respective box. 
     
     
         4 . The plate cooler as defined by  claim 1 , wherein the guide grooves on the upper and lower end, respectively, of the boxes are disposed on the edges thereof, and the adapter piece or the closing plate is fastenable by means of screws, which from above and below, respectively, engage nuts which are disposed in the guide grooves. 
     
     
         5 . The plate cooler as defined by  claim 4 , wherein the adapter piece and the closing plate have upright bores for the fastening screws. 
     
     
         6 . The plate cooler as defined by  claim 1 , wherein various adapter pieces with various connecting openings pointing in the desired direction are selectively usable. 
     
     
         7 . The plate cooler as defined by  claim 1 , wherein the plate elements are embodied as extruded profile sections of aluminum. 
     
     
         8 . The plate cooler as defined by  claim 1 , wherein the distributor box and the collection box are embodied mirror-symmetrically and are laterally aligned on both ends with the packet of plate elements. 
     
     
         9 . The plate cooler as defined by  claim 1 , wherein the adapter pieces are embodied as extruded profile sections of aluminum and have a vertical fluid channel, which adjoins the horizontal opening of the respective box, and also have a horizontal fluid channel, adjoining the vertical fluid channel, that adjoins the preferably vertical connecting opening for a line that leads away. 
     
     
         10 . The plate cooler as defined by  claim 1 , wherein the adapter pieces have grooves, open toward the outside and T-shaped in cross section, for attaching further connecting elements for the lines or pipes that lead away. 
     
     
         11 . The plate cooler as defined by  claim 1 , wherein further connecting elements in the form of feet serving to fasten the cooler are fastenable to the guide grooves of the collection box. 
     
     
         12 . A distributor box or collection box for a plate cooler for fluids, in particular hydraulic oil, wherein each box is fastenable on its ends on a parallelepiped packet of spaced-apart plate elements of the cooler, which include vertical fluid channels and air channels disposed between the fluid channels, wherein each box is embodied as a hollow extruded profile section of aluminum having a horizontal fluid channel, which is adapted to communicate with at least one line leading away, wherein each box is closed off on both ends and has guide grooves, open toward the outside and of T-shaped cross section, for attaching cooler connecting elements, and wherein each box has at least one horizontal opening, against which a connecting element in the form of a closing plate or an adapter piece can be placed. 
     
     
         13 . The distributor box or collection box as defined by  claim 12 , wherein each adapter piece is provided with a horizontal opening, which is placeable against the horizontal opening of the box, and with a connecting opening for the line leading away, and is fastenable to the guide grooves of the box.
