Definitions

  • the invention relates to a reciprocating piston internal combustion engine, the heat-loaded components of which are cooled by a cooling liquid, in particular according to the preamble of claim 1.
  • Liquid-cooled internal combustion engines usually have a liquid-air heat exchanger for the coolant, which is arranged in the longitudinal direction in front of the internal combustion engine and whose cooling air is conveyed by a fan which is driven by the internal combustion engine, the internal combustion engine and liquid-air heat exchanger being in a vehicle or, in the case of a stationary one Application, stored separately on a frame.
  • the liquid air heat exchanger With increasing power density and compactness of the internal combustion engine, the liquid air heat exchanger is becoming increasingly voluminous, so that it is becoming increasingly difficult to accommodate it, particularly in the vehicle.
  • the space conditions are exacerbated when hydraulic units are used, whose cooling capacity requirement can reach 50% of the cooling capacity requirement of the internal combustion engine.
  • the object of the invention is therefore to create a cooling system for liquid-cooled internal combustion engines that is as compact as possible and easy to install.
  • the cooling fan with a stator causes an increased cooling air pressure.
  • This enables the overall depth of the liquid-air heat exchanger to be increased or its flow resistance on the cooling air side to be increased by highly effective cooling fins.
  • the cooling air is heated up more and thus better utilized, which leads to a lower cooling air requirement and thus to a smaller size of the liquid-air heat exchanger.
  • the temperature difference between the cooling medium and ambient air is increased by the features according to the invention, which likewise increases the heating of the cooling air and reduces the dimensions of the liquid-air heat exchanger.
  • the cooling heat is reduced by reducing the cooled surfaces and thus a further reduction in the dimensions of the liquid-air heat exchanger is achieved.
  • the advantages of a compact liquid-air heat exchanger are used in a cooling unit which is separate from the engine. Whose arrangement can be chosen completely freely due to the chosen fan drive and can be optimally adapted to the respective installation conditions in vehicles or units.
  • An advantageous embodiment of the invention allows the cooling fan to be driven directly from the engine and thus creates the conditions for a compact engine heat exchanger unit.
  • the idler wheel has the advantage of protection against accidental contact for the impeller of the cooling fan, while the idler wheel fan is characterized by particularly low noise emissions and, since the distance between the idler wheel and the crankcase, cylinder and cylinder head may be very small, a shorter axial overall length of the Rotors allowed.
  • the design as a pressure blower has the advantage of a low blower power requirement, since the cooling blower conveys unheated cooling air.
  • the suction fan offers the advantage of uniform cooling air admission to the heat exchangers and simple guidance of the warm exhaust air.
  • the liquid-air heat exchanger is accommodated in a particularly space-saving manner and allows the warm cooling air to be advantageously removed. It may be advantageous to mount the liquid / air heat exchanger (s) separately from the engine and thus protected from its vibrations.
  • the connection between the motor-fixed cooling air blower and the air guiding scoop is advantageously designed so that a relative movement between the liquid air heat exchanger and the blower or motor is possible.
  • DE-AS 11 94 202 describes a reciprocating piston internal combustion engine, the cylinders of which are arranged in series and whose liquid-air heat exchanger is attached to the side of the reciprocating piston internal combustion engine.
  • a cooling air blower driven by the reciprocating piston internal combustion engine conveys the cooling air into a cooling air collecting space between the reciprocating piston internal combustion engine and the liquid-air heat exchanger.
  • this reciprocating piston internal combustion engine is a relatively low-load naturally aspirated engine, the coolant-air heat exchanger of which takes up the entire engine length despite the low cooling heat.
  • the coolant-air heat exchanger In modern, highly loaded and compact engines, especially supercharged engines, it is difficult to accommodate the liquid-air heat exchanger in the construction described, especially if additional space has to be created for an oil cooler on the device side of cooling systems with mechanical, hydrostatic and hydrodynamic gears or retarders with high cooling capacity.
  • liquid / air heat exchanger With a large number of production pieces, it is advantageous to manufacture the liquid / air heat exchanger (s) from only one element at a time. However, if engines of different outputs with smaller numbers are required, it is advantageous to assemble the individual heat exchangers in the manner of a modular system from several elements. This can be done by connecting the individual cooler elements in parallel and in series. In this way, a large variety of variants with few components is made possible.
  • An advantageous embodiment of the invention is directed to the recooling of coolant and working fluid, as they occur in particular with units with hydrodynamic or hydrostatic transmissions or with retarders.
  • the compact unit according to the invention offers the possibility of dissipating not only the heat loss from the engine but also the heat loss from auxiliary units.
  • FIG. 1 shows the arrangement of the reciprocating piston internal combustion engine 10, the cooling fan 2, the cooling liquid air heat exchanger 1 and the cooling air collecting space 6.
  • the arrangement of the reciprocating piston internal combustion engine 10 of the coolant heat exchanger 1, which are fastened to the carrying device 7 and of the cooling fan 2 with the scoop 8, which are connected by means of an elastic element 9, can be seen from FIG.
  • the very compact design of the units is shown in both figures recognizable and, in the arrangement according to FIG. 1, the complete absence of hose connections between the engine and heat exchanger.
