  • the invention relates to a heat exchanger for liquid heat exchangers, especially for different liquids in separate circuits, especially in internal combustion engines, which according to the generic features of Claim 1 on the inlet side with differently tempered streams of the first Liquid for alternately heating or cooling the second liquid is acted upon by valve control, with a valve device arranged on the inlet side controlled depending on a discharge-side temperature of one of the liquids is.
  • the intermediate temperature range is the inner cooling circuit and the outer cooling circuit the internal combustion engine is coupled to one another via a further valve, that this valve designed as a three-way valve depending on the temperature of the lubricating oil flowing out of the water / lubricating oil heat exchanger is controlled to achieve one of a cold and a warm proportion of cooling water mixed inlet of the water / lubricating oil heat exchanger.
  • An electrical temperature sensor can be used to record the lubricating oil temperature serve, the signals of the control one with the three-way valve in drive connection serve servomotor.
  • the lubricating oil can be in a drive connection with the three-way valve be supplied thermostatic device, the main danger there is that if such an arrangement is damaged, the liquids in the other circuit of the internal combustion engine and fail the internal combustion engine. Both arrangements are otherwise complex.
  • the set operating temperature of the only thermostat is for the heating of one or more oils by means of the water / oil heat exchanger disadvantageously low, so that the internal combustion engine from the water / oil heat exchanger when it heats up a relatively cold cooling water that in the warm-up phase effective internal cooling circuit is supplied with the disadvantage of a delayed Heating of the internal combustion engine.
  • the invention is based, for a generic heat exchanger the task the coolant control in particular for the phase of heating such to design that the temperature of the flowing coolant in the temperature level the temperatures of other devices connected to the cooling circuit is inexpensively adaptable.
  • the inventive arrangement of a temperature sensor in the course of Heat exchanger is advantageously of an optimally mixed Coolant is applied, which means significantly lower temperature fluctuations are connected.
  • the operating opening point can advantageously opposite a heat exchanger input control can be set significantly higher with the advantage of a higher temperature coolant in the drain of the water / oil heat exchanger, so that the temperature level of the outlet from the heat exchanger Coolant in the heating phase advantageous to the temperature level of the im inner coolant circulating coolant can be raised. Of the Warm-up of the internal combustion engine is thus significantly shortened.
  • a is used as the temperature sensor wax-filled expansion element provided with a rod-like piston, wherein the piston carries valve plates arranged at such a distance that at Every maximum stroke of the piston one valve plate in the open position and the other Valve plate is in the closed position.
  • This is an advantageously simple construction Valve device achieved.
  • this is preferably a separate one Component formed with a drain arranged between the valves, via which the valve device can be tightly connected to the inlet of the heat exchanger is, where appropriate a coupling of two sections Piston the valve device with the arranged in the heat exchanger outlet Expansion element connects.
  • This configuration according to the invention enables easy assembly and avoids jamming in the actuation of the valves.
  • the heat exchanger according to the invention is preferably used alternately Heating and cooling an oil for a drive unit using the Cooling water of an internal combustion engine equipped with a cooling water thermostat, the hot inlet of the valve device with a cooling water short circuit the internal combustion engine and the cold inlet of the valve device with a low-temperature cooler arranged in the cooling water circuit of the internal combustion engine communicates.
  • the invention is preferably used for heating and cooling the Fuel oil of the drive unit.
  • the internal combustion engine arranged temperature sensor Signals an electrical heating element arranged in the wax of the expansion element can be controlled to a higher operating opening temperature as well as a higher control temperature set expansion element depending to quickly control the oil temperature reached in the gearbox sump.
  • this Arrangement can advantageously be the temperature level of the heating phase coolant flowing from the water / oil heat exchanger almost have the temperature of the coolant circulating in the short circuit.
  • valves of the valve device with a servomotor individually or together in drive connection, the / the controlled via amplified signals from an electrical / electronic temperature sensor is or are.
  • the invention is based on an exemplary embodiment shown schematically in the drawing described.
  • the cooling water of the internal combustion engine 1 is warmed up via a Thermostats 4 circulated in the short circuit for rapid heating of the internal combustion engine 1 at operating temperature.
  • Cooling water of the internal combustion engine 1 is acted on in a valve-controlled manner at an early stage Heating the internal combustion engine oil 1.
  • This is represented by a cooling water inlet 5 of the heat exchanger 2 via its outlet 6 in connection standing valve device 3 with its hot inlet 7 via a line 8 a connecting the internal combustion engine 1 with an air / water heat exchanger 9 Lead 10 in connection.
  • Via a cooling water outlet 11 of the water / oil heat exchanger 2 is the cooling water via a line 12 and one Pump 13 supplied to the short circuit of the internal combustion engine 1.
  • the Valve device 3 also has a cold inlet 14, which is connected via a line 15 connected to a low-temperature cooler 9 'of the air / water heat exchanger 9 is.
  • valve device To control the differently tempered cooling water flows via the hot inlet 7 and the cold inlet 14, the valve device comprises 3 valves 16 and 17. These valves 16 and 17 can each be controlled separately, for example, in a map-controlled manner can be operated by a separate servomotor (not shown).
  • valves 16 and 17 are in one another fixed distance arranged operated together. As from the drawing further is the valve 16 controlling the hot inlet 7 in the open position and the cold inlet 14 controlling valve 17 controlled in the closed position.
