Heat Exchanger, Especially Oil/Coolant Cooler

Abstract

The invention relates to a heat exchanger, especially a stacked plate oil cooler ( 1 ) having a plate-type design. The heat exchanger is characterized in that two adjacent heat exchanger plates ( 2 ) define a space between them through which the heat exchange medium or a second medium that is to be cooled or heated flows. At one end of said heat exchanger, a base plate ( 3 ) lies substantially flat against the adjacent outmost heat exchanger plate ( 2 ) of the heat exchanger. Said base plate ( 3 ) is provided with a recess ( 5 ) whose contour follows that of the heat exchanger plate ( 2 ).

1 . A heat exchanger, especially a stacked plate oil cooler, having a plate-type design, with two adjacent heat exchanger plates defining an interspace through which a heat exchanger medium or a second medium to be cooled or to be heated flows, and at one end a base plate being provided which is in at least substantially flat contact with the adjacent outermost heat exchanger plate of the heat exchanger, wherein the base plate has a depression with a contour running in accordance with the heat exchanger plate. 
     
     
         2 . The heat exchanger as claimed in  claim 1 , wherein the flanks of the outermost heat exchanger plate bear, at least in their lower region, against the flanks of the contour of the base plate, which contour runs in a recessed manner. 
     
     
         3 . The heat exchanger as claimed in  claim 1 , wherein one edge of the outermost heat exchanger plate protrudes over the base plate. 
     
     
         4 . The heat exchanger as claimed in  claim 1  wherein the depression in the base plate is greater than the material thickness of the heat exchanger plate of the heat exchanger. 
     
     
         5 . The heat exchanger as claimed in  claim 1  wherein the depression in the base plate is at least as deep as the material thickness of the heat exchanger plate of the heat exchanger plus half of the clear height between the outermost heat exchanger plate, which bears against the base plate, and the second outermost heat exchanger plate. 
     
     
         6 . The heat exchanger as claimed in  claim 1  wherein the depression in the base plate is at least as deep as the material thickness of the heat exchanger plate of the heat exchanger plus the clear height between the outermost heat exchanger plate, which bears against the base plate, and the second outermost heat exchanger plate. 
     
     
         7 . The heat exchanger as claimed in  claim 1  wherein the contour in the base plate is produced by means of embossing, casting or machining. 
     
     
         8 . The heat exchanger as claimed in  claim 1  wherein the base plate has at least one supply opening for one of the media. 
     
     
         9 . The use of a heat exchanger as claimed in  claim 1  as a charge-air/coolant cooler, exhaust gas cooler, evaporator or oil cooler.
