Definitions

  • the invention relates to a cooling device for internal combustion engines of a type according to the features of the preamble of the claim.
  • 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. Furthermore, a relatively large volume of coolant in the heat exchanger and in the expansion space takes part in the heating process disadvantageously.
  • the object of the invention is to enable the use of such a cooling device with a thermostat integrated in the heat exchanger even with conventional air-flow heat exchangers, such as, in particular, for internal combustion engines for driving motor vehicles, and at the same time to improve the function and construction costs.
  • the invention solves this problem by the features according to the characterizing part of the patent claim.
  • the construction cost of such a cooling device is 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.
  • the heating process is favored because only the contents of the inlet and outlet lines and the mixing chamber of the thermostat take part.
  • a similar cooling device is described in the unpublished DE-A-31 17 543 and FR-A-2 481 791, in which the short circuit is arranged within the heat exchanger and connects the flow and return water boxes of the heat exchanger.
  • the thermostat housing is not suitable for the use of commercially available thermostat inserts.
  • 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.
  • An inlet connection 5 of a flow line (not shown), which conducts the coolant from the internal combustion engine into the heat exchanger 1 according to arrow 6, opens into the flow water box 3.
  • the cooler field 2 is flowed through horizontally by the coolant according to the arrows 7 and the heat to be dissipated from the coolant is also transferred to the coolant air 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 lid 9 containing pressure and vacuum valves.
  • the axis of the mutually 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 fastening flange 14 is sealed by a cover 18 against gradation of the 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 into an inlet chamber 23 arranged in the closure cover 18 form the housing 10.
  • the cutouts 22 are assigned window-like openings 24 in the partition of the housing 10 to the inside of the return water tank 4.
  • a narrow ventilation opening 25 also connects the inner cross section of the housing 10, which acts as a mixing chamber 26, to the interior of the return water tank 4 at a position lying above in the operating position formed 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 essential is lower and allows the use of inexpensive plastics.
