Definitions
- the invention relates to an expansion tank for a cooling circuit of an internal combustion engine according to the preamble of claim 1.
- an expansion tank of a cooling circuit of an internal combustion engine in which measures for reducing the foaming of the cooling liquid introduced into the expansion tank are provided.
- the cooling liquid is introduced into a chamber of the container via a cooling water pipe and there first meets a U-shaped trough provided in the chamber, via which the cooling liquid can drain into the liquid supply after overcoming the overflow edges of the trough.
- the coolant flowing out of the cooling pipe initially impacts an end face of the trough, which creates the risk of additional foam formation.
- an expansion tank is shown, in which a cooling water pipe opens below the liquid level in the expansion tank.
- the invention is therefore based on the object of providing measures in a cooling water expansion tank in which the cooling water escaping from the cooling water pipes and enriched with gas bubbles is braked in all possible driving situations , the motor vehicle (e.g. ascending or descending, cornering with high lateral acceleration) that foam formation in the expansion tank is largely avoided.
- the cooling liquid flowing into the expansion tank is to be vented before it is fed back to the actual cooling circuit of the internal combustion engine.
- the arrangement of the cooling water pipes in the expansion tank are coordinated with the liquid level in the expansion tank so that the Open the cooling water pipes at the level or below the liquid level. Foaming is essentially prevented by the fact that the kinetic energy of the inflowing water / gas mixture is effectively reduced by the higher viscosity of the liquid in the expansion tank. However, especially when driving uphill or downhill, it is no longer ensured that the coolant emerging from the cooling water pipes still flows below or at the level of the liquid. In this case, the curved guide walls provided in the expansion tank ensure that the kinetic energy of the inflowing cooling water is continuously reduced, so that foam formation is largely avoided in these driving situations as well.
- a particularly effective connection of the inflowing cooling liquid is obtained if the cooling water pipe opening into the chamber with the guide wall is aligned with its outlet mouth in such a way that the outflowing cooling liquid strikes the arcuate guide wall approximately tangentially.
- the expansion tank which is advantageously made of plastic, consists of an upper and lower shell, the guide wall and the cooling water pipe being integrated in the upper shell.
- a chamber system is also formed in the upper shell, in which the walls of the individual chambers are connected to one another via openings for pressure equalization.
- openings are provided, through which the cooling water pipe is passed; these openings are dimensioned such that they are simultaneously available as openings connecting the chambers.
- two cooling water pipes opening into the chamber system are advantageously provided, in which the first cooling water pipe is connected to a cooler and the second cooling water pipe is connected to the water jacket of the cylinder head of the internal combustion engine.
- 1 is a surge tank in a longitudinal section
- Fig. 3 is an interior view of an upper shell of the expansion tank
- Fig. 4 is an inside view of a lower shell of the expansion tank.
- the expansion tank 2 integrated into the cooling circuit of an internal combustion engine consists of an upper shell 4 and a lower shell 6, both of which are joined together, for example, by vibration welding.
- the inlet for the cooling liquid into the expansion tank 2 takes place through two pipes integrated in the upper shell 4, hereinafter referred to as cooling water pipes 8 and 10.
- the return or outlet 12 is formed in the lower shell 6.
- a chamber system is formed, which is described in more detail below.
- the two cooling water pipes 8 and 10 introduced into the upper shell 4 are led up to the two rearmost chambers 14d and 141 through openings 17a to 17c and 17d to 17f provided in the transverse walls 15a to 15c and 15g to 15i.
- the openings 17a to 17c and 17d to 17f are larger than the outside diameter of the cooling water pipes 8 and 10, so that the chambers 14a to 14d and 14i to 141 are connected via the openings 17a to 17c and 17d to 17f.
- the two cooling water pipes 8, 10 are clamped over the plastic formed from the bottom of the upper shell 4 18a to 18e in the upper shell 4.
- Breakthroughs 17a to 17c and 17d to 17f are provided in the intersections 19a to 19e of the transverse and longitudinal walls 15a to 15i and 16a to 16h through openings 20a to 20e connecting the chambers 14b to 141.
- arcuate guide walls 21 and 22 are provided, the functioning of which will be explained in more detail later in connection with the cooling liquid emerging from the cooling water pipes 8, 10.
- the two guide walls 21, 22 are formed in one piece from the bottom of the upper shell 4 and additionally anchored to the walls of the chamber system.
- the upper shell 4 there is an opening 24 which is provided with an internal thread and which serves to receive a pressure or vacuum valve, not shown.
- the lower shell 6 is also divided into individual chambers 26a to 261, the size or dimensioning of which essentially corresponds to the chambers 14a to 141 provided in the upper shell 4.
- the chambers 26a to 261 are in turn divided by corresponding transverse walls 27a to 27i and longitudinal walls 28a to 28h. Openings 29a to 29i and 30a to 30g are provided both in the transverse walls 27a to 27i and in the longitudinal walls 28a to 28h (except 28b).
- the expansion tank 2 serves to cushion or maintain the pressure in the cooling system of the internal combustion engine; it also has the function of ensuring ventilation of the cooling system.
- the cooling water pipes 8, 10 connected to the cooler or to the water jacket of the cylinder head of the internal combustion engine direct the cooling water into the rearmost chambers 14d and 141, respectively, in relation to the outlet 12 provided in the lower shell 6.
- the vehicle is in the normal position , ie it is neither strongly inclined about the longitudinal and / or transverse axis and there are no high longitudinal or transverse accelerations, then the position of the cooling water pipes 8, 10 relative to the liquid level in the expansion tank 2 is adjusted so that the ends of the cooling water pipes 8, 10 in Open at height or below the liquid level. Foam formation is thus essentially prevented by the fact that the kinetic energy of the incoming cooling liquid or the water / gas mixture is effectively reduced by the higher viscosity of the liquid in the expansion tank.
- the approximately tangential impact of the outflowing cooling water on the two arcuate guide walls 21, 22 represents a further measure to reduce the kinetic energy and thus to reduce foam formation.
- the arcuate guide walls 21, 22 provided in the expansion tank 2 ensure that the kinetic energy of the cooling water flowing into the two chambers 26d and 261 does not abruptly, but through the spiraling flow of the cooling water is gradually reduced, so that foam formation is largely avoided even in these driving situations.
- the cooling water is guided through the openings 29, 30 provided in the transverse and longitudinal walls 27, 28 through a multiplicity of chambers before it is returned to the actual cooling circuit of the internal combustion engine via the outlet 12 ,
- the cooling water in each chamber has the possibility of separating foam, since the openings 29, 30 lie below the water surface.
- the openings 17 and 20 provided in the chamber system of the upper shell 4 serve to ensure the pressure equalization of the air in the upper shell 4.
- the chambers prevent the cooling water from sloshing back and forth when the motor vehicle or the engine is at an incline; at the same time, the chamber system contributes to the stiffening of the expansion tank as a whole.
- the horizontally oriented marking ribs 31, 32 shown in FIG. 2 serve to indicate the fill level of the cooling water, with the marking rib 31 representing the maximum cold filling volume V max and the marking rib 32 representing the minimum cold filling volume V m jn.
