Definitions

  • the invention relates to an oil cooler.
  • a lubricating oil heat exchanger for an internal combustion engine which is designed with a housing made of light metal casting.
  • the housing is provided with cooling fins running parallel to the water flow direction.
  • This heat exchanger is arranged on the end face of the cylinder block of the internal combustion engine and thus disadvantageously leads to an increase in the overall length of the machine.
  • the plate covering the outer side of the central part can be made completely flat. Furthermore, the inwardly open channels are also covered by a flat plate, which forms a transverse channel for the oil adjacent to one transverse side at the edge of the central part and has an oil outlet opening there, and a distance from the edge on the opposite transverse side to form an oil inlet of the middle part.
  • the oil cooler is so small that it can replace the oil pan of an internal combustion engine, for example.
  • the oil cooler does not require more installation space than a previously installed conventional oil pan, so that an exchange is possible without any problems.
  • the manufacture of the oil cooler is due to the design of the central part as a die-cast part and the extremely simple shape of the flat plates, which, for. B. sheet metal can be very simple and inexpensive.
  • the oil cooler offers large heat exchange surfaces for the countercurrent media oil and cooling water.
  • the plate for forming the transverse channel for the oil has a raised end region.
  • the plate can be brought into the specified shape simply by folding, which represents a very low processing effort.
  • the walls of the oil channels and / or the water channels have ribs running transversely to the direction of flow. These ribs swirl the media flowing through the channels and thus intensify the heat exchange.
  • the illustrated embodiment of the oil cooler 1 essentially consists of a middle part 2, which has meandering walls 3, is closed on the long sides 21 and each has an upper and lower projecting edge 81 and 82.
  • the walls 3 alternately form upwardly open channels 4 for the oil and downwardly open channels 4 'for the coolant, generally cooling water.
  • the middle part 2 is covered at the top by an upper end plate 61 and at the bottom by a lower end plate 62.
  • the lower end plate 62 lies sealingly on the projecting edge 82 of the central part 2. No absolute tightness is required between the walls 3 and the lower end plate 62, since a leak would only create a connection between two channels 4 'for the cooling water, which has no negative consequences.
  • the upper end plate 61 even has a purely guiding function, since here the sealing of the oil cooler 1 via the upper edge 81 against the underside of the engine block (not shown) ) he follows.
  • the channels 4 and 4 ' run parallel to one another in the longitudinal direction in the oil cooler 1.
  • transverse channels 15 and 25 for the oil and transverse channels 15 'and 25' for the cooling water are arranged. which serve the distribution of the two media on adjacent channels 4 and 4 '.
  • Inlet openings 51 for the oil which here by simple Shortening the upper end plate 61 in the region of the ends 14 of the oil channels 4 and an outlet opening 52 'for the cooling water are provided in the upper side of the transverse channels 15 and 25' on the end face 22, while an outlet opening 52 for the oil and an inlet opening 51 'for the cooling water on the opposite end face 22'.
  • ribs 7 are arranged on the walls 3 of the oil channels 4, the function of which is to swirl the oil flowing vertically over them in order to achieve good heat distribution in the oil with a minimal increase in pressure and thus an intensive one To ensure heat exchange.
  • an oil cooler 1 without such ribs 7 or with ribs 7 is of course also conceivable in the water channels 4 '.
  • the longitudinal section shown in FIG. 3 through the oil filter 1 along the line AA in FIG. 2 runs through one of the oil passages 4 with ribs 7 arranged on the wall 3.
  • the end transverse passages 25 ', 15, 25 and 15' with the associated inlet and outlet Outlet openings 52 ', 51, 52, 51' for oil and cooling water can be clearly seen, as can the opposite flow profiles of the two media.
  • Figure 4 finally shows part of the oil cooler 1 also in longitudinal section, but here along the line B-B of Figure 2, which runs in a channel 4 'for the cooling water.
  • the channel 4 ' is closed at the bottom by the lower end plate 62, is smooth-walled and connected to the outlet opening 52' via the transverse channel 25 '.
