Definitions

  • the invention relates to an expansion tank for coolant according to the preamble of claim 1.
  • Expansion tanks for coolant are widely used in motor vehicles, especially passenger cars.
  • Such surge tank are usually formed from two halves produced by plastic injection molding, which are connected to each other, for. B. by welding. In this case, a horizontal weld is used in most cases in reservoirs for cooling liquid. Since the surge tank represents a pressure vessel, the total volume must be divided depending on the container shape for reasons of rigidity in several small chambers. These chambers also serve to calm and air separation of the cooling liquid / air mixture, which flows from the sampling points via the inlet connection in the expansion tank. The degassed liquid - cooling water - then flows back into a pump via an outlet connection and thus to the system.
  • the chambers are connected to each other both above, because of pressure equalization, as well as below, so that the cooling liquid / air mixture can pass from one chamber to another.
  • These Breakthroughs must be very laborious with slides in individual relatively small tool parts, which form the chambers are represented.
  • expansion tanks for cooling liquid have become known, which are divided vertically.
  • Such a vertically divided reservoir for cooling liquid of the type mentioned is from the DE-AS 24 37 502 known.
  • the container is made up of three parts, with the dividing wall being the central part to which the outer container halves connect.
  • the three container parts are connected to each other in the area of outer flanges of these three parts.
  • the partition is provided at the top and bottom with the openings. In this container thus two chambers are formed.
  • the inlet nozzle opens into one of the chambers, the outlet nozzle opens into the other of the chambers, ie it starts from this other chamber.
  • the dividing wall is arranged in the dividing plane, wherein the dividing wall separates the one chamber from the other chamber.
  • the expansion tank is structurally complex because, to form two chambers, the expansion tank is to be formed by three separate components, namely the two container halves and the partition, which are also to be connected to each other.
  • a vertically divided reservoir for cooling fluid is further from the DE 35 33 094 A1 known.
  • This surge tank has a refilling chamber for receiving the cooling liquid, an expansion chamber separated by a partition wall thereof, and a communication line connecting an upper portion of the refilling chamber to a lower portion of the expansion chamber.
  • the surge tank is composed of two shells with a vertical, passing through the connecting line dividing joint. Due to this vertical division of the entire container in two shells, it is possible to produce these two parts by means of a plastic injection molding and join together by means of appropriate connection methods.
  • the refilling chamber is normally filled to a certain level with coolant. With strong heating and thus volume expansion of the cooling liquid this runs from the refilling chamber via the line in the expansion chamber and is withdrawn with subsequent cooling of the cooling liquid back into the refilling chamber.
  • Another vertically divided reservoir for coolant is in the DE 80 15 573 U1 described.
  • This container also has an expansion chamber, a refilling chamber and a partition wall.
  • the object of the invention is to develop a compensating tank for coolant of the type mentioned so that it is simple and inexpensive to produce, with optimum efficiency regarding the reassurance and air separation of the cooling liquid / air mixture.
  • the object is achieved in that the container is divided so that the dividing plane of the container divides the respective chamber and in the region of the dividing plane, the openings are arranged.
  • the production cost for the expansion tank can be substantially reduced, because the breakthroughs can now be in the division.
  • the breakthroughs can thus be represented in the plastic injection molding process without slide.
  • the outlet nozzle opens through an opening in the bottom of the container in the outlet nozzle associated chamber.
  • Entry port opens adjacent the ceiling of the container through an opening in the side wall of the container into the inlet port associated chamber.
  • the container is provided with a filler neck, which opens through an opening in the ceiling of the container in one of the chambers.
  • the said plurality of chambers are formed in that the container has a further, substantially horizontally arranged partition wall, said partition being provided, in the dividing plane of the container, with apertures connecting superimposed chambers.
  • a particularly good efficiency when venting the cooling liquid is obtained when the cooling liquid / air mixture is not passed on the shortest route, but in a roundabout way through the expansion tank from the inlet nozzle to the outlet nozzle. This is done by the passage from one chamber to the other chamber, which can be accomplished by a clever arrangement of the apertures with respect to the division plane this deflection.
  • At least one breakthrough is formed by a recess in a container part, in particular a container half. Only this container part thus has the breakthrough, thus in the wall of this container part is laid while the container part adjacent this container part limits only one side of the opening.
  • each container part has a part of the respective breakthrough.
  • the expansion tank such that at least one opening is formed by a recess in a container part and a projection in the container part adjoining this container part.
  • the opening is laid very far in the one container part and the projection of the other container part, which partially projects into the recess of the former container part, forms the boundary edge of the opening.
  • This latter embodiment is to be seen in the aspect that the respective opening is arranged in the region of the dividing plane of the container.
  • the container such that an opening is formed by a recess in a container part and a tab connected to the other container part which partially covers the recess.
  • the container part provided with the tab does not have any part of this container part forming projection.
  • the said design is to be seen in particular as a function of the welding method and the representable tolerances used when connecting the container halves.
  • the surge tank in the region of the dividing plane of the two container halves on an outer welding edge for connecting the two container halves, which is very stiff and stable.
  • This welding edge can be used to accommodate means for securing the surge tank.
  • the vertical welding edge thus serves as a holder, in which the expansion tank can be inserted into a receptacle, for example from above. With horizontal attachment of the expansion tank, this can also be done by trained at the welding edge recordings.
  • the first embodiment according to the in the Fig. 1 to 3 shown compensating tank 1 for cooling liquid is vertically divided and has the two container halves 2 and 3. It illustrates breakthroughs in the division of the container and a graduated breakthrough.
  • the respective container half 2 or 3 is essentially formed as a cuboid hollow body, with respect to the orientation of the container 1, bottom 4, ceiling 5 and disposed between the bottom 4 and 5 ceiling side walls 6, 7.
  • the container half 2 is provided with a front wall 8
  • the container half 3 is provided with a rear wall 9.
  • four chambers 10, 11, 12, 13 are formed, which, due to the vertical division of the compensating container 1 in the two container halves 2 and 3, respective chamber halves 10 a, 11 a, 12 a , 13a of the container half 2 and chamber halves 10b, 11b, 12b, 13b of the container half 3 form.
  • the container half 3 is provided with a filling supports 19 for cooling liquid, an inlet connection 20 for bubble-enriched cooling liquid and an outlet connection 21 for bubble-free cooling liquid.
  • the outlet nozzle 21 opens through an opening 22 in the bottom 4 of the container half 3 in the chamber half 12b.
  • the inlet nozzle 20 opens, adjacent to the ceiling 5 of the container half 3 by an unillustrated breakthrough in the side wall 7 of the container half 3 in the chamber half 11b.
  • the filler neck 19 opens through an opening 23 in the ceiling 5 of the container half 3 in the chamber half 10b.
  • Each container half 2 or 3 is produced by plastic injection molding.
  • these recesses 24 form an unillustrated upper opening for blasenangereicherte coolant and pressure equalization of the chambers and a lower opening 25 for bubble-free coolant.
  • the horizontal partition half 15b is provided in the area between the chamber halves 10a and 13a with a protrusion 28 beyond the dividing plane of the container halves 2 and 3 and the other container half 3 in the region of the horizontal partition wall 15b in the transition from the chamber halves 10b and 13b with a recess 29 provided.
  • the length of the projection 28 is shorter than the depth of the recess 29, so that in an interconnected state of the two container halves 2 and 3 between the bottom of the recess 29 and the free front edge of the projection 28, a further opening 30 is formed between the Chambers 11 and 12.
  • the bubble-enriched cooling liquid flows through all four chambers 10 to 13, both with horizontal as well as with a vertical component, and this because of the lateral offset of openings to each other or to the inlet nozzle 20 and the outlet nozzle 21 with a component perpendicular to the parting plane of the two container halves 2 and 3.
  • the embodiment according to the 4 and 5 is compared to the embodiment of the Fig. 1 to 3 modified only in that instead of the projection 28 and the recess 29 between the chambers 10 and 13 each container half 2 and 3 a recess 26 in the sense of the embodiment of the Fig. 1 to 3 and thus having a breakthrough formed by these two recesses 26, which in its shape the opening 27 according to the embodiment of the Fig. 1 to 3 equivalent. All breakthroughs are thus in the division of the container.
  • the embodiment according to the FIGS. 6 to 8 is opposite to those after the FIGS. 1 to 3 modified in that, based on the opening 30 and thus the projection 28 which projects into the recess 29, a connected to the container half 5 tab 34 as far as the return 29 covers, as in the embodiment of the FIGS. 1 to 3 happens by means of the projection 28.
  • the container half 2 in the region of the opening 30 no protrusion 28, but it is in this area the tab 34, which is formed as a plate-shaped, rectangular body, connected to the partition half 15a and projects beyond this in the region of the end edge 18 addition.
  • FIGS. 9 and 10 show one over the embodiments according to the Fig. 1 to 5 simplified, not claimed embodiment.
  • the vertical partition 14 is provided, but not the horizontal partition 15.
  • there are only the recesses 24 in the upper and lower portions of the respective container half 2 and 3 are provided, which form the two openings 26.
  • only the two chambers 31 and 32 are formed.
