Definitions

  • the invention relates to a device for cooling or heating an internal combustion engine of a vehicle with a heat conductively connected to the engine cooling circuit having a cooling circuit pump, which is arranged for circulating coolant in the cooling circuit, and with a preheating branch, which is arranged parallel to the cooling circuit pump and is connected to the cooling circuit and has a Vormérmheizer and a preheating, the output side communicates with an output side of the cooling circuit pump and the input side with an input side of the cooling circuit pump, wherein in the Vordozensrmzweig a check valve is provided.
  • Such a device is already known from the prior art.
  • Vehicles with large internal combustion engines such as diesel-electric locomotives, can not be started in the cold state of the internal combustion engine.
  • a vehicle has a preheating system for the internal combustion engine, which operates either electrically, but usually operated fuel.
  • the preheating system heats up a cooling liquid circulated by a preheating pump via the internal combustion engine.
  • the cooling liquid which provides for the cooling of the internal combustion engine in later operation, serves as a heat source when cold. If the cooling water in the engine has reached a certain temperature, the preheater is switched off and the internal combustion engine can be started.
  • FIG. 1 shows an internal combustion engine 1 of a railcar, not shown figuratively a rail vehicle, which is cooled during operation of the internal combustion engine 1 via a cooling circuit 2.
  • the refrigeration cycle 2 has a refrigeration cycle pump 3, which circulates cooling fluid through the cooling passages of the cylinder heads and bushings 4, which conducts heat to the engine 1, and an external radiator 5.
  • a switching element such as a thermostat 6.
  • Parallel to the cooling circuit pump 3, a preheating branch 7 is arranged.
  • the preheating branch 7 has a preheating pump 8 and a preheating heater 9, which is followed by a check valve 10 in the pumping direction of the preheating pump.
  • the preheating branch 7 is connected to the cooling circuit 2 via a first preheating branch connection 11 and a second preheating branch connection 12.
  • a preheating circuit is provided by the preheating branch 7 as a parallel circuit to the cooling circuit 2. This means that during operation of the internal combustion engine 1, the cooling circuit pump 3 without the check valve 10 would continuously promote cooling fluid through the inactive preheating branch 7. However, this is rejected by some manufacturers of rail vehicles in the rail sector, so that the directions of circulation of Vormérm Vietnamese and cooling circuit 2 are opposite. In the opposite direction of rotation, it is possible through the check valve 10 to prevent the flow through the Vordozensrmzweiges 7 in engine operation of the vehicle.
  • FIG. 2 shows the device according to FIG. 1 in preheat mode.
  • the cooling circuit pump 3 is turned off.
  • the cooling liquid is therefore circulated solely by the preheating pump 8.
  • the cooling liquid enters the preheat heater 9 and the check valve 10 and The first preheating 11 in the cooling circuit 2.
  • the heat generated by the preheat heater 9 is supplied to the internal combustion engine 1, which is heated by means of its cooling channels in the cylinder heads and in the liners 4.
  • the external cooler 5 is separated from the cooling circuit 2 due to the thermostat 6, so that the cooling liquid flows back directly to the preheating pump 8.
  • FIG. 2 recognizable that due to the parked cooling circuit pump 3 coolant against the pumping direction of the cooling circuit pump 3 flows through it.
  • FIG. 3 shows the device according to FIG. 1 in engine operation.
  • the preheating pump 8 and the preheating heater 9 are turned off.
  • the cooling circuit pump 3 is switched on, which ensures circulation of coolant in the cooling circuit 2, wherein the thermostat 6 provides for a connection of the external cooler 5 with the cooling circuit 2.
  • the heat generated by the internal combustion engine 1 is thus discharged from the cooling liquid to the external cooler 5 and from this, for example, to the atmospheric air flowing through it.
  • Due to the check valve 10 is formed between the first preheating 11 and the check valve 10 in Voreriermzweig 7 a dead zone in which a flow of cooling liquid is prevented.
  • the object of the invention is therefore to provide a device of the type mentioned, which allows a cost-effective removal of heat from the coolant both in advance and in engine operation.
  • the invention solves this problem by a bypass branch with a bypass heat exchanger and a bypass pump, wherein the bypass branch by means of a first bypass connection with the Preheating branch and connected by means of a second bypass connection with the cooling circuit.
  • a bypass branch which has two bypass connections, wherein a first bypass connection is connected to the preheating branch and a second bypass connection opens into the cooling circuit.
  • a bypass pump is set, which is advantageously controlled independently of the preheating and the cooling circuit pump.
  • activation of the bypass pump causes heated liquid from the preheat heater to flow over the bypass branch. Since the bypass tap in the preheating branch is, for example, directly behind the preheating heater, heat is available to an external consumer, which is connected to the bypass heat exchanger, relatively quickly. At the same time it comes to heating of the internal combustion engine. During engine operation, the preheating pump and preheating heater are switched off.
  • the cooling circuit pump circulates the coolant through the engine and the external radiator.
  • stopped bypass pump is formed between the connection of the preheating branch and the check valve, as in the prior art, a dead zone in which a circulation of cooling liquid is suppressed.
  • the cooling fluid By switching on the bypass pump, however, the cooling fluid also flows through the bypass branch during engine operation, so that heat is again provided for one or more external consumers via the bypass heat exchanger.
  • the bypass connections are arranged relative to one another such that, during operation of the device, the lowest possible pressure drop occurs between them via the preheating branch and the cooling circuit.
  • the bypass connections are arranged in close proximity to each other. This ensures that no unwanted flow through the bypass branch occurs in both the preheat mode and during engine operation when the bypass pump is switched off.
  • the pressure drop between the bypass ports via the Vormérmzweig and the cooling circuit is substantially lower than the pressure drop across the bypass branch itself.
  • the low pressure drop between the bypass ports outside the bypass branch also has advantages in preheating.
  • bypass circuit Since only a very small pressure loss occurs between the bypass connections, the bypass circuit does not influence the preheating circuit, because no circulation in the bypass occurs when the bypass pump is stationary. Hydrodynamic influences on the circulation system during preheating are essentially eliminated in this way. Also, the flow profile of the cooling circuit is not or insignificantly influenced by the bypass circulation, ie by the flow of cooling fluid through the bypass branch. This feature of the device is desirable both by the manufacturers of the preheaters and in the manufacturers of internal combustion engines, since the theoretical flow calculations of the respective heat or cooling circuits remain virtually unchanged.
  • bypass connections are connected by a freely permeable pipe connection.
  • the freely permeable pipe connection are sections of the preheating branch or of the cooling circuit. According to this embodiment of the invention, it is possible to provide a very small pressure drop between the bypass ports.
  • the preheating branch is connected on the output side of the preheating pump to the first bypass connection as a bypass input, the cooling circuit on the output side of the cooling circuit pump being connected to the second bypass connection as a bypass output.
  • the cooling liquid heated by the preheating unit passes directly into the bypass branch, so that thermal energy, for example in the driver's cab, can be made available particularly quickly.
  • the preheating branch is connected on the input side of the preheating pump to the second bypass connection as a bypass output, the cooling circuit on the input side of the cooling circuit pump being connected to the first bypass connection as a bypass input.
  • the preheating of the preheated cooling fluid first passes into the engine, ensures its heating and only then in the bypass branch. In this way, a faster preheating of the engine is possible.
  • bypass heat exchanger of the bypass pump is connected downstream in the flow direction of the bypass branch.
  • the check valve is expediently arranged on the output side of the preheating pump in the preheating branch.
  • the first bypass connection is expediently a bypass input, which is connected between the check valve and the connection of the preheating branch to the cooling circuit.
  • the cooling circuit can be connected via a controllable valve to a cooler which is set up to cool the cooling liquid circulated in the cooling circuit.
  • the controllable valve is for example a simple thermostat. Deviating from this, however, a controllable check valve is used.
  • FIGS. 1 to 3 have already been described in connection with the prior art.
  • FIG. 4 shows an embodiment of the device 12 according to the invention, in addition to those associated with the FIGS. 1 and 3 components mentioned a bypass branch 13 which is connected to a first bypass port 14 as a bypass input to the preheating branch 7 and opens via a second bypass port 15 as a bypass outlet in the cooling circuit 2.
  • a bypass pump 16 and a bypass heat exchanger 17 are arranged, wherein the bypass heat exchanger 17 of the bypass pump 16 in the pumping direction of the bypass pump 16 is connected downstream.
  • the pumping direction of the cooling circuit pump 3, the preheating pump 8 and the bypass pump 16 is indicated in each case by an arrowhead which points into the respective pumping direction.
  • FIG. 5 shows the device according to FIG. 4 in preheat mode.
  • the preheat pump 8 in the preheating the preheat pump 8 is turned on, where is switched off against the cooling circuit pump 3.
  • the preheating pump 8 conveys the cooling liquid via the preheating heater 9, the check valve 10 to the first port 11 of the Vormérmzweiges 7 to the cooling circuit 2.
  • the bypass pump 16 is also switched on, so that cooling liquid heated by the preheating heater 9 is tapped from the bypass branch 13, guided via the bypass heat exchanger 17 and finally reaches the cooling circuit 2.
  • the bypass heat exchanger 17 it is therefore possible to supply external consumers, for example a heater of a driver's cab, with heat.
  • bypass input 14 and the bypass output 15 are connected via a direct connection, which are sections of the preheating branch 7 and the cooling circuit 2, respectively.
  • This direct connection can be flowed through freely. In this way, outside the bypass branch 13, a small pressure drop is provided between the bypass port 14 as a bypass port and the bypass port 15 as a bypass port.
  • the bypass pump 16 is turned off, the pressure drop for the coolant flowing over the bypass branch 13 is substantially greater than when it flows through the direct connection.
  • the circulation of the cooling liquid in the preheating operation is little influenced by the small hydraulic pressure difference between the bypass input 14 and the bypass outlet 15.
  • FIG. 6 shows the device 12 according to FIG. 4 in engine operation.
  • the bypass pump 16 is turned on.
  • cooling liquid is thus conveyed via the bypass branch 13 and thus via the bypass heat exchanger 17.
  • external consumers can be supplied with heat energy from the cooling liquid in engine operation.
  • FIG. 7 shows a further embodiment of the inventive device 12.
  • the bypass input 14 is connected to the cooling circuit 2.
  • the first bypass connection is arranged on the input side of the cooling circuit pump.
  • the bypass outlet 15 is connected to the preheating branch 7 and, on the input side, to the preheating pump 8. According to this arrangement, therefore, the cooling liquid is initially over the internal combustion engine 1, wherein this then reaches the bypass branch 13 in preheating.
  • the bypass heat exchanger 17 of the bypass pump 16 upstream in the direction of circulation.
  • a check valve 18, which can be actuated, for example, from the driver's cab, serves to reliably prevent a circulation of cooling fluid via the bypass branch 13.
