Definitions

  • the invention relates to a cooling device for internal combustion engines of a type according to the features of the preamble of claim 1.
  • the cooling device is provided and possible exclusively for liquid-cooled internal combustion engines with combined cooling by an engine coolant and an external coolant, in particular for watercraft drives.
  • the object of the invention is to enable the use of such a cooling device with a thermostat integrated in the heat exchanger also in all other conventional liquid-cooled internal combustion engines, such as in particular in internal combustion engines for driving motor vehicles.
  • the invention achieves this purpose by the features according to the characterizing part of patent claim 1.
  • This also enables general use in all liquid-cooled internal combustion engines.
  • the claims 2 to 5 contain features that enable the use of the invention in conventional coolers with heat exchange between the ambient air and the machine coolant particularly advantageous and the construction cost keep such a cooling device particularly low, since the return water tank of the cooler with the housing of the thermostat, apart from its cover, can be produced in one piece and as an easily molded plastic injection-molded part.
  • a heat exchanger 1 for air and coolant which is designed as a cooler for internal combustion engines of motor vehicles, such as, in particular, automobiles and motorcycles, is designed as a cross-flow cooler. It has a flow water box 3 and a return water box 4 on both sides of its cooler field 2.
  • the cooler field 2 is flowed through horizontally by the coolant according to the arrows 7 and the heat to be dissipated is thereby transferred from the coolant to the cool air also flowing through the cooler field - perpendicular to the plane of the drawing.
  • the return water tank 4 has on its top a filler neck 8, which is equipped at its filler opening with a conventional cover 9 containing pressure and vacuum valves.
  • a housing 10 of a thermostat 10 ', a short-circuit connecting piece 11 and an outlet piece 12 is formed in one piece in a substantially multi-cylindrical internal cross section.
  • the axis of the concentric cylinder sections of the housing 10 and the short-circuit connecting piece 11 is arranged in the direction of the air flow directed from the plane of the drawing.
  • the outlet nozzle 12 extends radially downward, or possibly to the side or possibly also obliquely to the side and down, depending on the continuation of a return line, not shown, to the internal combustion engine.
  • the housing 10 of the thermostat 10 'contains a conventional thermostat insert 13 with a mounting flange 14 with a radiator valve opening, an expansion element 15, a radiator valve plate 16 and a short-circuit valve plate 17.
  • the mounting flange 14 is sealed by a cover 18 against a gradation of Clamped internal cross section of the housing 10.
  • the closure cover 18 has a flange connection (not shown) with a sealing ring 19 at the end region 20 of the housing 10 and axial projections 21 arranged in a crown, the end faces of which abut the fastening flange 14 and whose window-like recesses 22 have inlet openings for the cooling liquid in an inlet chamber arranged in the closure cover 18 23 of the housing 10 form.
  • the cutouts 22 are assigned window-like openings 24 in the partition of the housing 10 to the interior of the return water tank 4.
  • a narrow ventilation opening 25 connects the inner cross section of the housing 10, which acts as a mixing chamber 26 at an upper position in the operating position also with the inside of the return water tank 4.
  • the gradation of the inner cross section of the housing 10 from the mixing chamber 26 to the short-circuit connecting piece 11 is designed as a valve seat 27 for the associated inlet opening 28 to the mixing chamber 26.
  • the return water tank 4 is formed with the housing 10 of the thermostat 10 'in one piece from metal or in particular from plastic in die casting or injection molding, so that both the manufacturing costs and the weight of the cooling device according to the invention are low. This is also favored by the fact that the housing 10 of the thermostat 10 ', in contrast to its usual arrangement on the housing of internal combustion engines, is not exposed to its maximum temperature, but rather to the maximum temperature of the coolant, which is much lower and enables the use of inexpensive plastics.
