    Title: Cooling device
    Description
    The invention relates to a cooling device
    Traditionally, an already known cooling device has a heat exchanger provided with a pump provided with a supply line and a return line, as well as an electronics unit, to provide a cooling medium with a predetermined temperature.
    The object of the invention is to provide a cooling device which is distinguished by efficient handling in the case of variable use.
    This object is achieved with a cooling device according to the invention with the features of claim 1.
    Because in the cooling device according to the invention at least two pumps, a heat exchanger connected to at least two pumps and associated electronic units are arranged horizontally next to each other in a single housing, the cooling device according to the invention can provide cooling media set at different temperatures and at the same time a supporting surface with a relatively large surface area for, for example, a container can be made available for placing directly on the cooling device firmly, for example with the various modules to be brought to the correct temperature.
    Additional effective designs of the invention are the subject of the sub-claims.
    Additional more efficient designs and advantages of the invention follow from the following description of an exemplary embodiment with respect to the figures of the drawing.
    Shown is:
    FIG. 1 is a perspective view of an exemplary embodiment of a cooling device according to the invention with a drip tray placed thereon and
    FIG. 2 is a perspective view of the exemplary embodiment according to FIG. 2 with the drip tray removed and looking into a housing.
    FIG. 1 shows a perspective view of an exemplary embodiment of a cowing device 1 according to the invention. The cooling device 1 has as its housing a device housing 2 of, for example, sheet steel, the front wall 3 of which enclose side walls 4, 5, rear wall 6 and bottom wall 7 thereof in the device according to Fig. 1 by a drip tray 8 covered as a tray. A number of at least partially rotatable running rollers 9 are arranged on the bottom wall 7, on which the cooling device 1 can be moved.
    From the representation according to Fig. 1, it can be seen that a forward-looking control console 10 is provided on the front wall 3, which in this exemplary embodiment carries a first switch 11 and a second switch 12, wherein each of them operates a cooling circuit in its operation. can be activated or switched off. Each cooling cycle is associated with a first temperature controller 13 or a second temperature controller 14, via which the relevant temperature of a cooling medium of the relevant cooling cycle can be set independently of the or any other cooling cycle. Each cooling circuit can be [filled] via a first filler connection piece 15 or via a second filler connection piece 16, which are arranged on the front wall 3, preferably with water as a heat dissipation medium, the level of which is each via a first level display 17 or via a second level display. level display 18, which are also arranged on the front wall 3, is visible.
    The drip tray 8 shown in Fig. 1 has a tray bottom 19 which closes with the circumferential outer edge of the housing 2 and which is surrounded by a circumferential edge 20. The bucket edge 20 extends away from the device housing 2 pointing substantially rectangularly away from the tray bottom 19.
    The drip tray 8 is releasably connected to the device housing 2 with a number of fastening elements 21. In the exemplary embodiment according to Fig. 1, an overflow opening 22 is introduced on the side running along the rear wall 6 of the housing 2, in order to discharge liquid collected in the drip tray 8 from a certain filling height. Furthermore, it can be seen from the representation according to Fig. 1 that on the side of the frying edge 20 opposite the overflow opening 22 and adjacent to the front wall 3 of the housing 2, a frying handle 23 is provided with which the drip tray 8 after loosening the fastening elements 21 can be easily removed from the device housing 2.
    FIG. 2 shows in perspective view the exemplary embodiment of a cow device 1 according to FIG. 1 with drip tray 8 removed from the device housing 2 and therefore not shown in FIG. 2, with an view of an inner volume enclosed by the device housing 2. It follows from Fig. 2 that two housing handles 24 are provided on the side walls 4, 5 on the side remote from the bottom wall 7, by means of which the cooling device 1 can be easily handled, in particular can be rolled, but can also be lifted. Furthermore, it can be seen from the representation according to Fig. 2 that on the rear wall 6 for a first cooling circuit a first supply line 25 and a first return line 26 and for a second cooling circuit a second supply line 27 and a second return line 28 are provided. The first cooling circuit has a first pump 29 and a first cooling hose 30, while the second cooling circuit is correspondingly equipped with a second pump 31 and with a second cooling hose. The first cooling circuit further has a first cooling compressor 33, while the second cooling circuit is equipped with a second cooling compressor 34.
    The first pump 29 and the first cooling hose 30 are arranged in a first inner housing 35 arranged inside the device housing 2, while the second pump 31 and the second cooling hose 32 lie correspondingly in a second inner housing 36.
    For controlling the two cooling cycles, a first electronics unit 37 and a first electronics unit 38 are each provided, which in the exemplary embodiment according to FIG. 2 are at a safe operating distance from the inner housings 35, 36 in the region of the sensor. facing side wall 5 lie between the first inner housing 35 and the front wall 3. On the other side wall 4, opposite the electronics units 37, 38, the cooling device 1 has a heat exchanger 39 for both cooling circuits.
    The cooling compressors 33, 34 as well as the inner housing 35, 36 with the pumps 29, 31 and with the cooling hose 30, 32 are arranged horizontally next to each other when the cooling device 1 is arranged according to the regulations.
    For the rest, the supply lines 25, 27, the return lines 26, 28, the pumps 29, 31, the cooling hose 30, 32, the cooling compressors 33, 34 and the heat exchanger 39 are similarly known known cooling devices with a single cooling circuit and connected to each other. additional components required for operation, such as valves, switches, refrigerant collection devices, refrigerant dryers and sight glasses, which are not further specified in Fig. 2 for reference reasons.
    Finally, it can be seen from the representation according to Fig. 2 that the side walls 4, 5 at their parts adjacent to the front wall 3 are provided with openings which are each covered by removable ventilation grilles 40, in particular in the inner volume enclosed by the device housing 2. obtain a flow of air in the area of the heat exchanger 39.
    From the display according to hg. 2, it can be seen that by arranging the inner housing 33, 34, of the electronic units 37, 38 and of the heat exchanger 39 when the cooling device 1 is arranged in accordance with the instructions with the rollers 9 downwards in the horizontal plane to a relatively large space-occupying device housing 2, which results in a comparatively large surface area of the drip tray 8 of the drip tray 8 which, compared to the individual components of the cooling device 1, now has a large surface area as well as indivisible and therefore uniformly manageable bearing surface. can serve for modules provided by the cooling circuits. As a result, a relatively complex structure such as, for example, test devices to be maintained at different temperatures can be produced.
    An additional characteristic of the exemplary cooling device 1 according to Fig. 1 and Fig. 2 is a temperature control by means of preferably two solenoid valves 41, 42, 43, 44 per cooling circuit for fuel gas and coolant inflow into the cooling hose 30, 32. The solenoid valves 41, 42, 43, 44 switch on and on with the constant switching of the electronic units 37, 38, through which a mixed refrigerant gas flows into the cooling hose 30, 32 and thus a constant temperature of the water to be cooled or other liquids are also obtained. This mixed refrigerant gas is preferably introduced in front of refrigerant injection valves 45, 46 to ensure trouble-free control of the refrigerant injection valves 45, 46.
