Definitions

  • the present invention relates to a cooling system in a motor vehicle with a cooling circuit in which at least one internal combustion engine, a pump and a cooling device are arranged.
  • the present invention addresses the problem of providing a cooling system in a motor vehicle, which has a significantly lower energy consumption compared to previously known cooling systems.
  • the present invention is based on the general idea, in a cooling system with a cooling circuit in which at least one consumer to be cooled, for example an internal combustion engine, a pump and a cooling device are arranged, a pressure side and a suction side of the pump via a short-circuit line, that is to connect via a bypass line, which is opened in the event of unnecessary cooling and thereby no longer conducts an at least predominant part of a coolant flow through the internal combustion engine and the entire cooling circuit, but diverts it into a much less resistant short circuit ( DE 102 44 829 A1 and DE 101 55 337 A1 ).
  • valve device For deflecting or splitting the coolant flow to the internal combustion engine or to the short circuit line bypassing the pump while a valve device is used, which requires significantly reduced actuating forces due to the now existing short-circuit and thus both smaller and more economical in terms of energy consumption can be formed.
  • the valve device according to the invention is arranged in the region of the short-circuit line, for example in the region of a branch of the short-circuit line from the cooling circuit or in the region of a junction of the short-circuit line in the cooling circuit.
  • valve device is adjustable between at least two positions, wherein in the first position, at least a majority of the coolant flow through the short-circuit line and in the second position flows at least a majority of the coolant flow through the engine and not through the short-circuit line.
  • first position at least a majority of the coolant flow through the short-circuit line
  • second position flows at least a majority of the coolant flow through the engine and not through the short-circuit line.
  • any intermediate positions which allow any division of the coolant flow between the actual cooling circuit and the short circuit. If, for example, no cooling effect is required in the internal combustion engine or another consumer to be cooled, the valve device can be transferred to its first position and thereby the cooling medium can be pumped through the short circuit relatively comparatively little resistance.
  • valve device With the valve device according to the invention and arranged in the region of the short-circuit line, it is thus possible to control the cooling requirement in the internal combustion engine and thus also the power of the coolant pump relatively flexibly. If the internal combustion engine does not require cooling power, then the valve device is simply adjusted to its first position, so that at least a predominant part of the Coolant flow through the short-circuit line and no longer flows through the engine or the cooling device.
  • the valve device is designed as a proportional valve.
  • a proportional valve Compared to a valve device which can be switched back and forth only between two positions, such a proportional valve has the great advantage that it can be switched to any desired intermediate position, whereby an almost freely selectable division of the coolant flow flowing through the internal combustion engine and the short-circuit line is possible.
  • An activation of the valve device according to the invention can be carried out, for example, by means of an already existing engine control device, which also detects a temperature of the cooling medium in addition to the respectively occurring operating state of the internal combustion engine, for example full load or partial load.
  • a cooling system 1 which can be arranged, for example, in a motor vehicle, has a cooling circuit in which at least one internal combustion engine 2, a pump 3 and a cooling device 4 are arranged.
  • a short-circuit line 5 bypassing the pump 3 is now provided which connects a pressure side of the pump 3 to a suction side thereof.
  • a valve device 6 is provided which is adjustable at least between two positions.
  • the valve device 6 can be used as a so-called multi-way valve, in particular as 3-2-way valve, be trained and in the first position, as these according to the Fig. 1 and 4 is shown, at least a majority of the coolant flow, preferably the entire coolant flow through the short-circuit line 5, while in the second position, as shown in the FIGS. 2 and 3 is shown, at least a majority of the coolant flow, preferably the entire coolant flow through the internal combustion engine 2 and not through the short-circuit line 5 passes.
  • the respective coolant flow is represented by corresponding flow arrows.
  • a bypass line 7 bypassing the cooling device 4 may preferably be provided in the cooling system 1 according to the invention, it being conceivable that the short-circuit line 5, as shown in FIG Fig. 1 is shown, also opens into the bypass line 7.
  • the valve device 6 according to the invention in particular in the case in which the internal combustion engine 2 requires no or only a smaller cooling, a switching of the same possible, whereby the coolant flow exclusively or at least partially by the much lower-resistance short circuit, as shown in the Fig. 1 is pumped, so that in this case, the pump 3 can be operated at a much lower power.
  • the according to the Fig. 1 shown state is, for example.
  • the valve device 6 requires significantly reduced actuating forces and can thus be both smaller and more economical in terms of energy consumption. Without the presence of the short-circuit line 5 significantly larger actuating forces for adjusting the valve device 6 would be required, which means a higher energy consumption.
  • valve device 6 itself would have to be made larger and thus heavier, which also means an increased energy requirement.
  • valve device 6 is arranged downstream of the pump 3 in the cooling circuit, while these according to the Fig. 2 is arranged upstream of the same in the cooling circuit.
  • the valve device 6 may, for example, be designed as a throttle device and / or pneumatically, electrically or hydraulically controlled.
  • an engine control unit 8 can be used in particular to control this, which detects, for example, an operating state of the internal combustion engine 2, in particular a partial load or full load operation, and / or a temperature of the cooling medium.
  • Fig. 1 can also be used in the cooling systems 1 according to the FIGS. 2 and 3 to be available.
  • a thermostat 9 may be provided in the junction region of the bypass line 7 in the cooling circuit.
  • the valve device 6 is designed as a poppet valve or as an annular slide valve, wherein due to a so-called “fail-save” -Pinzips the valve device 6 is always designed so that they in unconfirmed, that is in Vietnamese anêtem state, in their second position remains, thereby ensuring sufficient cooling of the engine 2 in any case.
  • the valve device 6 according to the invention is designed as a proportional valve, whereby any division of the coolant flow through the engine 2 and the short-circuit line 5 can be effected.
  • valve device 6 is arranged in the junction region of the short-circuit line 5 in the bypass line 7, wherein also in this case at a transfer of the valve device 6 in its first position an at least predominant part of the coolant flow through the short-circuit line 5 flows, since these compared to the leading through the engine 2 and the cooling device 4 cooling circuit has a significantly lower flow resistance.
  • bypass line 7 is purely optional, so that these - as in Fig. 5 is shown - can also be omitted.
  • the valve device 6 makes it possible to regulate a volume flow in the cooling circuit through the internal combustion engine 2 with the possibility of reducing this volume flow to zero, if necessary. If the valve device 6 is actuated, the pump 3 conveys the cooling medium in the low-resistance short circuit and not by other consumers to be cooled, such as the internal combustion engine 2. If, however, a low cooling capacity in the engine 2 is required, the thermostat 9 or a so coupled valve device 10 prevent a flow of coolant through the cooling device 4 and this pass through the bypass line 7 (see. Fig. 3 ).
  • the valve device 10 coupled to the thermostat 9 can be switched such that the coolant flow is no longer through the bypass line 7, but rather flows through the cooling device 4 (see. Fig. 2 ).
  • the valve device 10 coupled to the thermostat 9 can be designed in the same way as the valve device 6.
  • any intermediate cooling stages can furthermore be set.
  • a small actuating force is at least the valve device 6 possible.
  • An intervention in the main coolant flow of the internal combustion engine 2 is also not required.
  • Fig. 6 is a possible prototype of the valve device 6 shown with a solenoid 11 which moves a valve stem 12 by generating a spatially constant magnetic field as possible.
  • the valve device shown has two inlets 13, 13 'and an outlet 14, whereby any mixing of the input streams into a common output stream is possible.
  • the valve device 6 not according to the invention has two valve disks 15, 15 'arranged on the valve tappet 12, the valve disk 15 preferably being formed integrally with the valve tappet 12.
  • the valve disk 15 ' is made in the example shown as a separate component and secured by means of a securing element 16 on the valve stem 12 in the axial direction 17.
  • valve device 6 Between the valve plate 15 'and a valve seat ring 18, a spring 19 is provided which biases the valve disk 15 against the valve seat ring 18 and thus in its closed position.
  • a spring 19 is provided which biases the valve disk 15 against the valve seat ring 18 and thus in its closed position.
  • a combined valve plate 15 "and two springs 19 'and 19" are provided.
  • the spring 19 ' is designed as a safety spring, while an overpressure function can be ensured by means of the spring 19.
  • the combined valve disk 15 has two valve disks 20 and 20' which, depending on the switching position, fit snugly against associated valve seats 21 and 21 '.
  • the 10a and 10b show the two extremal switching positions of the valve device 6, wherein in Fig. 10a the bypass line 7 closed and in Fig. 10b the bypass line 7 is open, such as during a cold start.
  • the individual parts of the valve device 6, in particular the valve plate 15, 15 can be made of metal or plastic.
