Collecting tank, heat exchanger, and method for producing a collecting tank

Abstract

The invention relates to a collecting tank ( 11 ), especially a charge-air tank or a coolant tank, consisting of plastic and comprising at least one tie rod ( 12 ) which is integrated into the collecting tank ( 11 ) or is connected to the same in a fixed manner or in such a way that it forms a single component therewith. Said tie rod ( 12 ) comprises at least one insert ( 13 ).

1 . A collecting tank, in particular a charge-air tank or a coolant tank made of plastic, with at least one tie rod, which is integrated into the charge-air tank or coolant tank, formed in one piece with it or connected to it in a fixed manner, characterized in that the tie rod comprises at least one insert.  
   
   
       2 . The collecting tank as claimed in  claim 1 , wherein the insert is a reinforcing element and/or a cooling element.  
   
   
       3 . The collecting tank as claimed in  claim 1 , wherein the insert is a metal insert part, a metal strip, a metal tube, an insert part of fibrous material, a tape of fibrous material and/or a fiber.  
   
   
       4 . The collecting tank as claimed in  claim 3 , wherein the fibrous materials comprise carbon and/or glass fibers.  
   
   
       5 . The collecting tank as claimed in  claim 1 , wherein an encapsulation of the insert with a plastic is provided.  
   
   
       6 . The collecting tank as claimed in  claim 5 , wherein the encapsulating material is the same plastic as that of the remaining collecting tank.  
   
   
       7 . The collecting tank as claimed in  claim 1 , wherein the insert is formed in a hollow manner.  
   
   
       8 . The collecting tank as claimed in  claim 7 , wherein the insert is formed such that it can be flowed through by a fluid.  
   
   
       9 . The collecting tank as claimed in  claim 1 , wherein the insert consists of a material with good heat conduction.  
   
   
       10 . The collecting tank as claimed in  claim 1 , wherein the insert protrudes outward beyond the outer side of the collecting tank and/or ends in a projection of the collecting tank.  
   
   
       11 . A heat exchanger, in particular a charge-air cooler or a coolant cooler, in particular for a motor vehicle, with heat exchange tubes which open out into at least one collecting tank, wherein at least one collecting tank is formed as claimed in.  
   
   
       12 . A method for producing a collecting tank as claimed in  claim 1 , wherein the insert is directly molded in during the production of the collecting tank and/or is subsequently inserted and sealed into it with an integral bond.
