Housing element having an integrated heat exchanger

Abstract

A device is provided, in particular an oil sump, for an engine and/or a transmission arrangement. The device includes a housing element for the formation of a side wall structure and for holding an operating fluid and a heat exchanger for heat exchange with the operating fluid, the heat exchanger configured to be supplied with temperature control fluid and having a heat exchange element. The heat exchange element forms at least one through-flow duct for the through flow of the operating fluid and at least one through-flow duct for the through flow of the temperature control fluid.

1 . A device for an engine, a piston machine and/or a transmission arrangement, comprising:
 a housing element for the formation of a side wall structure and for holding an operating fluid; and   a heat exchanger configured to exchange heat with the operating fluid, the heat exchanger configured to be supplied with temperature control fluid and having a heat exchange element that forms at least one through-flow duct for the through flow of the operating fluid and at least one through-flow duct for the through flow of the temperature control fluid.   
     
     
         2 . The device according to  claim 1 , wherein the heat exchange element is part of the housing element, with the result that the heat exchange element and the housing element are formed by one and the same component. 
     
     
         3 . The device according to  claim 1 , wherein the heat exchange element comprises a plurality of through-flow ducts for the operating fluid and a plurality of through-flow ducts for the temperature control fluid. 
     
     
         4 . The device according to  claim 1 , wherein the heat exchange element comprises a wave or up-and-down structure, with the result that the at least one through-flow duct for the operating fluid and the at least one through-flow duct for the temperature control fluid are formed. 
     
     
         5 . The device according to  claim 1 , wherein the through-flow ducts for the operating fluid extend adjacent and parallel to the through-flow ducts for the temperature control fluid. 
     
     
         6 . The device according to  claim 1 , wherein the through-flow ducts for the operating fluid and the through-flow ducts for the temperature control fluid overlap alternately. 
     
     
         7 . The device according to  claim 1 , wherein at least one opening via which the operating fluid can be fed to the at least one through-flow duct for the operating fluid, is formed within the housing element. 
     
     
         8 . The device according to  claim 1 , wherein a bottom element is arranged above the heat exchange element, between the side wall structure, within the housing element. 
     
     
         9 . The device according to  claim 8 , wherein the bottom element at least partially spans the at least one through-flow duct for the operating fluid. 
     
     
         10 . The device according to  claim 8 , wherein the bottom element is spaced apart at the end from the housing element in order to form the at least one opening. 
     
     
         11 . The device according to  claim 8 , wherein the at least one opening is formed in the bottom element. 
     
     
         12 . The device according to  claim 8 , wherein the bottom element is movable in order to close the at least one opening and/or in order to form a bypass opening, such that operating fluid can be discharged while bypassing the at least one through-flow duct for the operating fluid. 
     
     
         13 . The device according to  claim 1 , wherein the heat exchanger has a bottom closure element and the heat exchange element extends between the bottom closure element and the bottom element. 
     
     
         14 . The device according to  claim 8 , wherein the bottom element is cast or mounted onto the housing element. 
     
     
         15 . An engine comprising:
 a device comprising:
 a housing element for the formation of a side wall structure and for holding an operating fluid, and 
 a heat exchanger configured to exchange heat with the operating fluid, the heat exchanger configured to be supplied with temperature control fluid and having a heat exchange element that forms at least one through-flow duct for the through flow of the operating fluid and at least one through-flow duct for the through flow of the temperature control fluid. 
   
     
     
         16 . A commercial vehicle comprising:
 an engine including a device comprising:
 a housing element for the formation of a side wall structure and for holding an operating fluid, and 
 a heat exchanger configured to exchange heat with the operating fluid, the heat exchanger configured to be supplied with temperature control fluid and having a heat exchange element that forms at least one through-flow duct for the through flow of the operating fluid and at least one through-flow duct for the through flow of the temperature control fluid.
