Definitions
- the invention relates to a fluid cooling device as a structural unit with a drive motor which drives a fan wheel which can be rotated in a fan housing, at least one fluid being able to be conveyed from a storage tank into a hydraulic working circuit which basically heats the fluid during operation and leads to an associated heat exchanger from which the fluid returns cooled to the storage tank.
- EP 0 968 371 B1 discloses a generic fluid cooling device, the storage tank of which is trough-shaped in the manner of an oil container and partially includes the drive motor and the associated fluid pump with raised trough edges in the manner of a half-shell. Between the raised tub edges of the storage tank, a housing part made of sheet metal is arranged, which receives the fan wheel and forms an air duct for the heat exchanger, through which the fluid is guided.
- an extension of the housing part has a foot part arranged below the storage tank, which is designed in the manner of a shoe serving to fasten the device, the sole of which has fastening webs at least partially beyond the length of the sole.
- a relatively large-volume storage tank is provided as an oil container, which nevertheless saves space in a compact design as part of the unit designed fluid cooling device is in that it includes parts of the same at least partially to save space.
- good accessibility of the motor and fluid pump unit is also guaranteed for assembly and maintenance purposes. Because of the foot part mentioned, a secure, space-saving fastening of the entire fluid cooling device to fixed components and housing walls is also possible.
- the housing part composed of sheet metal, which forms the fan housing for the fan wheel that can be driven by means of the drive motor, is costly to manufacture on the one hand due to the variety of parts and, on the other hand, vibrations can be introduced into the sheet metal housing part during operation of the fan wheel with undesired resonance effects.
- the sheet metal housing part is also hardly suitable for damping the fan noise during operation, so that the operation of the known fluid cooling device is relatively loud. Due to the sheet metal part construction of the housing part, there are also sometimes sharp transitions and shoulders within the air duct, so that the free air flow in the area of the fan wheel is impaired due to turbulence, which in turn has an unfavorable effect on the cooling capacity of the respective heat exchanger.
- the object of the invention is to further improve the known solution while maintaining its advantages in such a way that a further reduction in the manufacturing and operating costs can be achieved while at the same time reducing noise.

- the fan housing which is preferably made of a plastic material, also allows improved damping for the fan wheel noise, which is particularly true in the case that the storage tank is filled with fluid with the fan housing, which further improves the damping behavior. Due to the design of the fan housing made of plastic material, the design options within the scope of conventional plastic product manufacturing processes are broader and increased, whereby sharp transitions in the area of the air ducting can be avoided and a stepless, continuous air ducting prevents turbulence and flow losses, which is energetically favorable and the overall Lowers operating costs with the fluid cooling device according to the invention.
- the drive motor drives at least one fluid pump, which is arranged together on a shaft train with the rotatable fan wheel, and / or that the respective fluid pump, provided with its own drive, is part of the fluid cooling device elsewhere.

- the bottom-side trough part serves in particular to securely and functionally fix the entire fluid cooling device on machine parts;
- the fluid cooling device in a self-supporting manner directly on the floor, on a machine frame or the like.
- stator-side trough part forms a receiving option for the fan wheel, which can be integrated into the storage tank in a space-saving manner, and starting from the stator-side trough part, a holding possibility is created for the drive motor, for the fan wheel together with the respective fluid pump and assignable piping.
- the hollow ring delimits a first opening cross-section, which is covered by the respective heat exchanger, and has a second opening cross-section, which faces the drive motor for the fan wheel.
- the cross-section of the opening of the hollow ring facing the respective heat exchanger is selected to be larger in cross-section than the cross-section of the opening cross-section facing the drive motor, the cross-section change in question being continuous in particular by means of conical air guiding surfaces.

- Fluid pump 14, 16 is assigned an independent hydraulic circuit.
- the fluid in the respective hydraulic working circuit then regularly heats up accordingly and is then recooled by the fluid cooling device to a predeterminable temperature value.
- a heat exchanger 24 (cooler) of conventional design is used for each of the two circuits, from which the fluid supplied via connection points (not shown) can be returned to the storage tank 20 via discharge lines 26.
- the fan wheel 12 with the electric motor 10 is designed in the manner of an axial suction fan, in which the air passes through the fins of the respective heat exchanger, which are not shown in detail. shear 24 is sucked via the fan wheel in the direction of the electric motor 10, which is additionally cooled along its cooling fins by the air flow. 1, the air flow flows from the right to the left through the fan wheel 12.
- the storage tank 20 consists of a plastic material, preferably a polyethylene plastic material (LLDPE) and is preferably produced in one piece using the rotational molding process. As shown in FIGS.
- parts of the storage tank 20 form the fan housing 28, which, as shown in the prior art, is not formed from sheet metal parts but from the plastic materials mentioned, the fan housing 28 as part of the storage tank 20 forms a hollow chamber which encloses the fan wheel 12 on the outer circumference side with a predeterminable radial distance and otherwise has a box-shaped structure towards the outside.
- the aforementioned storage tank 20 has a bottom-side tub part 30, on which a stator-side tub part 32 is placed and connected in one piece to the bottom-side tub part 30.
- the two tub parts 30, 32 mentioned form a type of hollow ring 34 in which the fan wheel 12 is rotatably arranged.
- the bottom-side tub part 30 has a square bottom surface 36 and a rear side surface 38 facing the viewer in the direction of view of FIG. An upper one extends between the two mentioned steps 42
- Bottom plate of the bottom-side trough part 30 parallel to the bottom surface 36 of the same.
- a kind of hollow plate-shaped basic structure is created for the bottom-side tub part 30, on which the two steps 42 are placed on the edge side, as is the stator-side tub part 32 at a free end region of the bottom-side tub part 30, which lies opposite the rear side surface 38.
- the upper base plate 46 there are two inclined incisions 48, each provided with a marking 50, which make it possible to read the maximum and minimum fill level in the storage tank 20, specifically as viewed from above, with the drive motor 10 located above between the extends in both incisions 48 and thus does not impair readability.
- stator-side trough part 32 is also to be provided with fluid, it is advisable to provide the level markings 50 laterally and again in a readily accessible manner on the two lateral boundary surfaces 44 in the upper region. Furthermore, there are reversion openings provided in the upper base plate 46 with end plugs 52, which facilitate cleaning of the tank or container from the outside after its removal.
- the hollow ring 34 mentioned has a first opening cross section 54, which is covered by the respective heat exchanger 24. In the illustration according to FIG. 2, the relevant heat exchangers 24 are not shown for the sake of better illustration.
- the heat exchangers 24 in question are supported in the assembled state on the front or front side 56 of the storage tank 20 and thus cover the first opening cross-section 54 of the fan housing 28 designed in the manner of a hollow ring.
- the hollow ring 24 has a further, the first opening cross-section 54 opposite second opening cross-section 58, which otherwise faces the drive motor 10 for the fan wheel 12.
- the second opening cross-section 58 In the area of the second opening cross-section 58, the latter is designed in the manner of a hollow cylinder and the wall thickness area of the hollow cylinder is such that the blades of the fan wheel 12 move circumferentially by means of the drive motor 10 at a predeterminable radial distance along the hollow cylindrical second opening cross-sectional shape.
- the opening cross section 54 of the hollow ring 34, which faces the respective heat exchanger 24, is chosen to be larger in diameter than the diameter of the opening cross section 58, which faces the drive motor 10.
- the relevant change in cross-section takes place continuously, in particular by means of conical air guiding surfaces 60. Because of these air guiding surfaces 60, there is a continuous change from the rectangular cooler shape of the heat exchangers 24 to the circular shape of the fan wheel 12. This, on the one hand, makes the alignment the air flow is improved and it is ensured in such a way that the corners and edge regions of the heat exchangers 24 are also flowed through with the full air flow.
- the change in cross-section need not be present over the entire area of the hollow ring 34 in the front area of the inflow direction, rather straight-line transitions may also be present here, in particular in the area of the lateral boundary surfaces 44; however, it is important that a quasi-continuous air flow is achieved between the first opening cross section 54 and the second opening cross section 58.
- the storage tank 20 forms the fan housing 28 with its bottom-side tray part 30 and with its stator-side tray part 32, the sound propagation of the fan wheel 12 is greatly damped and the usual fan noise is thus significantly reduced.
- the damping effect in this regard can be further improved if the storage tank 20 is also filled with fluid in the region of the tub part 32 on the stand.
- the area of the air duct between the first opening cross section 54 and the second opening cross section 58 can be used with the air guiding surfaces 60 as a cooling surface, since it is in direct contact with the fluid medium.
- the tank solution to be stored also becomes a result of this solution significantly increased, since the fan housing 28 can now be used as an additional tank volume.
- the stator-side trough part 32 is arranged in the area of the one free end of the bottom-side trough part 30 standing vertically thereon and the length of the bottom-side trough part 30 is such that it corresponds at least to the installation length of the respective fluid pump 14, 16 together with the drive motor 10 (cf. .1).
- a holding plate 62 extends transversely over it in the region of the second opening cross-section 58 and is firmly connected to the rear of the stand-side wall part 32, for example via a screw connection, and to increase the safety there is between the holding plate 62 and a fan grille 64 is arranged on the actual fan wheel 12, which indeed allows air to pass through, but otherwise ensures that an operator does not inadvertently intervene in the high-speed rotating fan wheel 12, provided the fluid cooling device is in operation.
- the longitudinal axis of the electric motor 10 and of the first and second fluid pumps 14, 16 takes place parallel to the upper base plate 46 of the base-side trough part 30 and the rotary bearing for the fan wheel 12 is integrated in the holding plate 62.
- the angular arrangement of the storage tank 20 with the freely projecting electric motor 10 has proven to be very vibration-stable in practical tests and also allows the electric motor 10 to be optimally cooled in the axial suction air mode of the fan wheel 12.
- the holding plate 62 has corresponding cutouts 66 by as little as possible to impair the free passage of air through the opening cross sections 54, 58.
- the storage tank 20 can be separated by a single or double separator.
- wall 68 which in the present exemplary embodiment, however, only extends along the bottom-side trough part 30, is divided into two separate tank chambers 70, 72.
- each of the two tank chambers 70, 72 there is a predeterminable amount of fluid of an assignable fluid, for example in the form of hydraulic medium; but there is also the possibility of filling one tank chamber with one type of fluid, for example in the form of hydraulic medium, and the other tank chamber with another type of fluid, for example with a coolant in the form of a water-glycol-containing emulsion or the like Accordingly, it is possible to use the two fluid pumps 14, 16 to deliver a fluid of the same type separately or two fluids of a different type. Depending on the respective pump output for the two fluid pumps 14, 16, a faster cooling circuit can also be achieved and the cooling capacity can also be adjusted by a suitable choice of a heat exchanger 24 and its size. Thus, with the fluid cooling device, cooling and possibly also heating tasks can be solved in a wide range when starting up systems with a fluid, such as hydraulic medium.
- the number of tank chambers can also be increased further, in which case one fluid pump would preferably be assigned to one or more interconnected tank chambers and a corresponding heat exchanger or cooler 24 in the associated circuit each have a separate chamber volume, the partition 68 mentioned would also have to be carried out accordingly in the relevant stand-side trough part 32. If the partition 68 is designed as a double-chamber partition, which optionally forms a recess that can be filled with ambient air to the bottom surface 36 of the bottom-side tub part 30, In this way, particularly good thermal insulation and reliable media separation between the two chambers 70, 72 can be achieved.
- the hollow ring 34 as the fan housing 28 has on its side 74 facing away from the bottom-side trough part 30 two tank openings 76, through which the fluid medium can be introduced into the storage tank 20.
- the arrangement of the filling openings 76 on the top of the fluid cooling device is very easy to service due to the good accessibility.
- the relevant service-friendly arrangement results because the fan housing 28 is designed as a tank construction. It has also proven to be particularly advantageous to use a milky, cloudy plastic in order to enable an operator or maintenance person to visually check the level indicator without any further measures (level meter).
- the milky clouding of the plastic also protects the respective fluid medium from aging, for example from ambient light.
- the storage tank 20 can be produced from polyethylene material in a rotational molding process in a particularly cost-effective manner.
