Definitions

  • the invention relates to a device for cooling a recirculated fluid according to the preamble of claim 1.
  • Such devices are used in particular in commercial vehicles, such as concrete mixers or the like, where they serve as an oil cooler cooling, for example, a fluid-forming transmission oil.
  • a associated collecting tank is provided, which on the one hand forms a depot for the oil and on the other hand, a receiving chamber for a filter through which the oil is guided and cleaned, before about a connected to the reservoir suction line is recycled into the circulation.
  • the collecting container of a known device is made of cast iron, in particular cast aluminum, and is arranged in the mounted position of the device on the heat exchanger, which is provided opposite feet, by means of which the entire device is attached to the example commercial vehicle.
  • the design of the collecting container as a casting is often disadvantageous, both with regard to the handling of the device and with respect to the production.
  • the formation of the casting sump also results in a relatively high weight, which results in a corresponding sizing of the heat exchanger (s) connected thereto, since, as mentioned, the sump is mounted on the heat exchanger.
  • the handling of the known device is also disadvantageous insofar as the filter placed in the collecting container must be removed laterally for inspection and cleaning. This requires draining the oil in the sump, at least into a region below a lateral insertion opening for the filter.
  • the known device is not suitable to meet the requirements for cost optimization both in terms of manufacturing and operation. This applies equally to functional reliability, which is not guaranteed to the desired extent.
  • the invention has for its object to further develop a device of the generic type so that it is easier and less expensive to manufacture and operable and their reliability is improved.
  • the new device is characterized first of all by the fact that their collection container, regardless of the required or required volume, can be produced in a simple manner.
  • the collecting container is also conceivable, however, to design the collecting container as a so-called extrusion profile, a plastic extruded profile which can likewise be made available in any desired length.
  • the jacket of the collecting container has a very smooth, non-porous inner surface, which significantly improves the functional reliability compared with a collecting container according to the prior art.
  • a lid is formed as a foot, with which the device is anchored stationary, as well as arranged with a heat exchanger on the same side another foot.
  • the shell frontally closing lid screw channels can be provided, which are introduced during extrusion of the profile tube and in the preferably self-tapping
  • Screws that are guided through the lid are screwed.
  • the filter can be inserted through the top lid, with a cover provided for this purpose is closed by a cap connected to the filter.
  • an outlet connection of the filter opens into a connecting piece, to which a return line acting as a suction line is connected.
  • this connection piece with the foot-side cover of the collection connected container and provided with an oil drain, through which a trouble oil change in the overall system is possible.
  • feet can be formed as sheet metal parts, which are made by forming. It is also conceivable, these feet also from one
  • FIG. 1 shows a device according to the invention in a front view
  • Figure 2 is a perspective view of the device.
  • a device for cooling a recirculated fluid which consists in its basic structure of a heat exchanger 1 and a collecting container 6 operatively connected thereto.
  • the heat exchanger 1 has a heat sink 2, preferably a tube cooler, to which a distributor tube 3 is connected to an inlet 5, via which the circulated oil in the heat sink 2 can be guided.
  • a drain 4 is connected to the heat sink 2, which in its configuration corresponds to the distributor tube 3 and via which the fluid guided through the heat sink 2 is fed into the collecting container 6. reached.
  • the flow direction of the fluid is indicated by arrows.
  • the collecting container 6 is arranged laterally adjacent to the heat exchanger 1 and connected thereto.
  • a jacket 7 enclosing the interior of the collecting container 6 consists of a section of an extruded profile tube, this jacket 7 being cuboid in the example.
  • the end of the jacket 7 is closed by a cover 8.
  • the fitting on the lower end face of the jacket 7 cover 8 is also designed as a foot 9 with two spaced apart extending legs 19 ( Figure 2). Another foot 9 is connected to the drain 4.
  • a filter 10 is arranged for cleaning the fluid which has been passed, which is then led to a connected connecting piece 13 to a return line 14, which is designed as a suction line and conveys the cleaned fluid to the lubricating point when the fluid For example, is used as transmission oil.
  • the connecting piece 13 is fastened to the rear side of the cover 8 facing away from the jacket 7 and connected to the filter 10 via a pipe socket 20.
  • screw 1 1 are screwed into the self-tapping screws 12, by means of which the cover 8 are fixed to the jacket 7.
  • other cross-sectional shapes of the collecting container 6 are conceivable, e.g. round or polygon.
  • a sight glass 17 is inserted into the jacket 7, via which the fill level of the fluid in the collecting container 6 can be seen.
  • the filter 10 can be pulled out through an unrecognizable opening of the upper lid 8, for example for cleaning.
  • a cap 21 is arranged on the filter 10, which is connectable to the associated lid 8.
  • the heat sink 2 in which pipes and fins through which the fluid flows, is permeable to air.
  • a fan 15 is arranged, with an electrical connection 16 which can be connected to an on-board electrical system.
  • a thermostat can be embedded in the jacket 7, with which the temperature of the fluid can be monitored.
  • the introduction of both the sight glass as well as the thermostat so far particularly simple, as in the wall of the shell 7 only a corresponding hole must be drilled.
  • the connecting piece 13 has an outlet 18, which is closed by a sealing screw and via which emptying of the collecting container 6 or of the entire system is possible.
