Definitions
- the invention relates to a fluid cooling device as a structural unit with a Motor that drives a fan wheel and a fluid pump that draw fluid from one Takes the oil tank and pumps it into a hydraulic working group that holds the fluid heated, and leads to a heat exchanger from which the fluid is cooled in the oil tank returns according to the features of the preamble of claim 1.
- Related fluid cooling devices also referred to as oil air coolers can be used as compact structural units (DE 44 00 487 A1) in hydraulic or install liquid circuits in systems or machines.
- the Liquid cooling is usually based on the inlet temperature difference between liquid and ambient air, volume flow and air flow dependent. Thermal problems caused by multi-shift operation and higher air temperatures can also be prevented.
- the oil tank must be appropriately large Have volume.
- the object of the invention to further improve the known fluid cooling devices, that they are still compact and still have one have relatively large volume liquid or oil containers as well as maintenance and are easy to assemble.
- a fluid cooling device solves this problem with the features of claim 1.
- the fluid cooling device is between the raised tub edges of the oil tank Arranged housing part that receives the fan wheel and an air duct forms for the heat exchanger through which the fluid is guided.
- the sole side at least partially over the Sole length also has fastening webs. Because of that The foot section is a space-saving, secure attachment of the entire fluid cooling device possible on fixed components and housing walls.
- the fluid cooling device has an electric motor 10, which has a fan wheel 12 and drives a fluid pump 14.
- the fluid pump 14 takes fluid from one Oil container 16 and pumps it into a hydraulic working group 18, of which 5 with the usual short names, the connections for the Hydraulic lines are shown.
- the fluid heats up accordingly and is to be heated up by the fluid cooling device a predeterminable temperature value can be cooled.
- a heat exchanger is used for this 20, from which the fluid returns cooled to the oil container 16.
- the drive direction of the fluid pump 14 is in the viewing direction of FIG. 2 seen there indicated by an arrow 22.
- the oil container 16 is trough-shaped and with raised tub edges 24 in the manner of a half-shell educated. This includes at least partially from the bottom the motor 10 and the fluid pump 14. Between the raised tub edges 24 of the oil container 16, a housing part 26 is arranged, which Fan wheel 12 receives and an air duct 28 for the heat exchanger 20 forms through which the fluid is guided.
- the fastening shoe 32 in question is, as is particularly the case in FIGS. 1 and 3 show, hollow box-shaped and the toe 38 points in the direction of the engine 10.
- the mounting shoe 32 is thus in its hollow box-like Shell arrangement transversely to the longitudinal orientation of the trough-shaped oil container 16 arranged and in operative connection with this. Initiated vibrations in operation of the fluid cooling device can thus be safely via the Fixing shoe 32 in the respective stand device or the underground derived.
- the fastening shoe 32 is bulge-resistant and allows especially through the sloping fastening part between the toe 38 and the horizontal support surface for the underside of the oil tank pan 16 a safe, low-vibration introduction of force into the fluid cooling device detachable area.
- the oil reservoir 16 is in the region of the engine 10 in a trough-like cross section below it dimensioned smaller than the comparable cross-sectional area of the oil container 16, which is arranged below the fluid pump 14. This results in a chamber system of the oil container 16 with different ones Cross-sectional areas.
- the fan wheel 12 is from a drive shaft 40 penetrated or firmly connected to this on impact, in the manner of a Hollow shaft includes the output shaft 42 of the motor 10 and the drive shaft 44 drives the fluid pump 14.
- the relevant axis and shaft arrangement is oriented coaxially to a longitudinal axis 46 of the fluid cooling device. The exact relationships result in particular from the sectional view according to Fig.3.
- the hydraulic working circuit 18 with a hydraulic accumulator 48 for example in the form of a membrane accumulator, the cooling device fluid-carrying in connection with a protection of the printing or working group against Pressure fluctuations allowed and fluid volume losses can compensate.
- the relevant hydraulic accumulator 48 is shown in FIG Fig.3 omitted.
- the supply line opening into the hydraulic accumulator 48 50 of the heat exchanger 20 also opens into the part of the oil container 16 which is arranged below the motor 10, one leading to the fluid pump 14 Feed line 52 into the oil container 16 arranged below it empties.
- the fluid cooling device for pressure monitoring a conventional manometer 54, for filtering the fluid at least one filter unit 56 and for a level control of the oil container 16 at least a relevant display device 58. Otherwise, the oil tank 16 provided with a filling filter 60 for the fluid.
- the circuit diagram after the 5 explains the function of the fluid cooling device in more detail.
- the fluid pump 14 removes fluid, in particular hydraulic oil, via the feed line 52, out of the oil tank 16 and conveys this via the filter unit 56 in Direction of connection P of the hydraulic circuit 18.
- the pressure gauge 54 monitors the pressure in the hydraulic working group 18 and Hydraulic accumulator 48 compensates for pressure fluctuations in the system. That is in the hydraulic Working group 18 heated fluid returns via the connection point T back into the fluid cooling device and passes through the supply line 50 in the heat exchanger 20 and from there appropriately cooled in return in the oil tank 16 for a new circulation.
- Both the air cooler as well as the hydraulic working group can with further useful connections A, B, M, MS, T1 and P1 may be provided. restrictors as well as pressure relief valves of conventional design secure the hydraulic Circle against overload.
