Definitions

  • the invention relates to an oil cooler in a disk design with at least one disk package provided with an inlet and an outlet, which can be flowed through, which is arranged in a housing provided with an inlet and an outlet and through which flow can flow in the longitudinal direction thereof, and with between the sides of the disk package and the opposite walls of the housing arranged transversely to the longitudinal direction of the housing sealing strips.
  • an oil cooler of the type mentioned in that in the case of flow of cooling water through the disk package and oil through the housing, the disk package is accommodated in an outer cage at least on the two sides running in the longitudinal direction of the housing, which has at least two to the disk package pointing, transverse to the longitudinal direction of the housing has grooves which engage in corresponding recesses in the side edges of the discs of the disc package, that the sealing strips are arranged between the outer cage and the housing, that in the pairs a disc Forming half-shells touching knobs are stamped, and in the interconnecting openings in the disks which enable the flow of the cooling water through the disk pack, baffles are provided which reduce or prevent direct flow through the disks from the inlet opening to the outlet opening.
  • the side of the window package is understood to mean the outer boundary surfaces of the window package that do not face the cover of the housing to which the window package is attached and extend in the longitudinal direction of the housing.
  • an oil cooler of smaller size is sufficient for a given cooling capacity because the liquid with poorer thermal conductivity, namely the oil, has a larger heat transfer surface on the outside of the panes than the cooling water inside the panes.
  • the pills in the outer cage, which engage in recesses in the side edges of the disks, also simplify the assembly of the disk package.
  • the baffles in the disks improve the heat transfer to the cooling water. This effect is also supported by the shape of the knobs in the half-shells forming the disks; the knobs also serve to increase the rigidity of the half-shells.
  • the manufacture of the oil cooler can also be simplified in that the sealing strips are received in the grooves on the outside of the outer cage.
  • the measure that the guide plates in the disks have approximately the shape of a circular cylinder segment whose central axis coincides approximately with the central axis of the inlet opening / outlet opening can serve to further improve the heat transfer to the cooling water.
  • the rigidity of the disks can be further improved by soldering knobs facing one another to the half-shells forming a disk.
  • the outer cage can expediently consist of solderable metal sheet, which results in the possibility that the outer cage is soldered to the disk package.
  • oil baffles can be arranged between the disks.
  • the disks, the guide plates provided therein, the outer cage and the oil guide plates are made of the same aluminum alloy, so that electrochemical voltages which could have a corrosive effect cannot arise as a result of different materials.
  • the housing of the oil cooler can be part of a housing block of an oil filter which is produced by die casting.
  • a housing 1 of the oil cooler is provided, which is closed by a screwed-on cover 2 and sealed by means of a seal 3.
  • a disk package 4 with an outer cage 5 is attached to the cover 2.
  • Grooves 6 are formed in the outer cage 5, which face the disk package 4 and which engage in corresponding recesses 7 in the disks of the disk package 4.
  • This arrangement of grooves 6 and recesses 7 ensures the correct position of the disks consisting of half-shells 12 in the course of the assembly of the disk package 4 in the outer cage 5, which at the same time simplifies assembly and prevents incorrect half-shells 12 from being inserted.
  • On the outer sides of the outer cage 5 6 molded seals 8 are inserted into the grooves, which engage in corresponding recesses 9 in the inner walls of the housing 1.
  • nozzles 10 and 11 for the inlet and outlet of cooling water are attached, which establish the connections with the corresponding inlet openings and outlet openings in the panes of the pane package 4.
  • the - not shown in the drawing connections of the interior of the housing 1 with the oil filter for the inlet and the outlet of the oil are made in the housing block.
  • Half-shells 12 which each form a disc of the disc package 4 in pairs, have mutually facing knobs 13 which touch one another in the assembled state of a disc and are connected to one another.
  • 12 guide plates 14 are formed on the half-shells, which partially enclose the inlet openings / outlet openings of the disks and have approximately the shape of a circular cylinder segment, the central axis of which coincides approximately with the central axis of the inlet opening / outlet opening.
