Definitions
- the invention relates to a cooling system of a motor vehicle according to the preamble of Claim 1.
- cooling systems of motor vehicles are known in which a cooling module is used an expansion tank can be filled with coolant.
- the coolant is a Filling pipe in the lowest possible position in the cooling system in a pipe area fed into a water pump, which supplies the internal combustion engine with coolant. This lowest point is usually a connecting line between a radiator outlet of the cooling module and an intake of the water pump.
- the internal combustion engine flows, for example, that of the internal combustion engine incoming coolant via corresponding supply lines via an expansion tank on the one hand and, if necessary, via further devices, such as, for example Heating heat exchanger on the other hand in the connecting line between the radiator outlet of the cooling module and the suction system of the water pump.
- a cooling module on the one hand and the opening arrangement of an end section this inlet line into a radiator outlet (outlet side) of the cooling module on the other hand can advantageously be avoided that the if necessary, higher temperature coolant with that in the cooling module, if necessary lower temperature coolant mixed immediately. This can otherwise losses in heating output and a cooling of the internal combustion engine during this Low load operation can be effectively avoided.
- Other advantages include short ones and easier to move cable connections that are integrated in the cooling module can.
- the cooling system 1 schematically shows a cooling circuit of a cooling system 1 of a motor vehicle.
- the cooling system 1 essentially has a cooling module (coolant cooler) 2, from which via connecting lines 18, 19 by means of a water pump 13 and a thermostat 14 an internal combustion engine 5 can be supplied with coolant. In doing so, the funding of coolant via the water pump 13 to the cooling module (coolant cooler) 2 by means of the thermostat 14 only from a defined temperature.
- Parallel to Cooling module (coolant cooler) 2 which comes from the internal combustion engine 5 Coolant flows through the inlet line 19, the expansion tank 6 in turn can Coolant via an engine ventilation line 9 coming from the internal combustion engine (5) or Take up via a water cooler ventilation line 8 coming from the cooling module 2.
- a heating heat exchanger 7 via a combustion engine 5 coming heating flow line 10 are supplied with coolant.
- the cooling module 2 can be on the top Drain coolant through the radiator ventilation line 8 to the expansion tank 6. about a short-circuit line 15 (bypass line) can reverse coolant if necessary Direction from the Thermosat 14 into the water pump 13.
- additional lines of further, here not mentioned coolant-carrying devices through the water box 17 of the Cooling module 2 are passed.
- additional lines of further, here not mentioned coolant-carrying devices through the water box 17 of the Cooling module 2 are passed.
- According to an embodiment variant not shown here can be introduced at the front of the cooling module 2 and passed directly through it Filling line 11 and heating return line 12 combined into a single line his.
- FIG. 2 schematically shows an excerpt of a detail of the one shown in FIG. 1 Cooling system 1 shown.
- the coming from the expansion tank 6 are simplified Filling line 11 and the heating return line coming from the heating heat exchanger 7 12 combined into a common inlet line 11, 12, which on the vehicle front of the cooling module (coolant cooler) 2 directly through its water tank 17 passed in a lower area and in the end area of the radiator outlet 4 arranged at the mouth.
- this end area of the radiator outlet 4 is one any mixing of possibly higher temperature coolant from at least one an inlet line 11, 12 with possibly lower temperature coolant from the cooling module 2 without an adverse effect.
- Is located above the water tank 17 a cooling network 16 of the cooling module 2.
- the one which is guided through the water tank 17 can be Section of the at least one inlet line 11, 12 either a part of this inlet line 11, 12 itself or, alternatively, by a separate one, at least an inlet pipe 11, 12 connected pipe 20 may be given.
- the tube 20 can either be an integral part of the water box 17 or alternatively as a separate one Component inserted in the water tank 17 and soldered, welded or glued to it his.
- This can cause the otherwise existing disadvantage of heat loss in the low-load range of the internal combustion engine or when operating a vehicle heater be prevented.
