Definitions

  • the present invention relates to an expansion tank according to the preamble of claim 1 which is intended to be included in a cooling system of a motor vehicle.
  • the invention also relates to a cooling system for a motor vehicle provided with such an expansion tank.
  • a combustion engine of a motor vehicle is cooled by means of coolant which is circulated in a cooling system.
  • coolant which is circulated in a cooling system.
  • the cooling system is provided with an expansion tank which can accommodate the surplus coolant generated in connection with the expansion of the coolant.
  • the boiling point of the coolant rises with increasing pressure, and it is therefore desirable to maintain a certain positive pressure in the cooling system when the engine is in operation to thereby prevent coolant boiling.
  • the expansion tank is provided with a pressure relief valve which ensures that the pressure in the expansion tank cannot exceed a predetermined pressure level.
  • an expansion tank of the above-mentioned type Another important function of an expansion tank of the above-mentioned type is that it should be possible for the coolant received in the expansion tank to be deaerated in the expansion tank before leaving the expansion tank.
  • the air which has been absorbed by the coolant when circulating through the cooling circuit of the cooling system and which therefore accompanies the coolant to the expansion tank is intended to rise to the surface of the coolant volume received in the expansion tank in order to accumulate in an air-filled space at an upper part of the expansion tank.
  • the coolant in the expansion tank is deaerated.
  • Some cast components included in a combustion engine of a motor vehicle have a very complex construction with narrow ducts and grooves and it is therefore difficult to completely clean such engine components from all foundry sand particles and metallic particles.
  • Such remaining particles and other particulate contaminants may be mixed with the coolant when the coolant flows through the coolant ducts in the combustion engine and through other parts of the cooling system.
  • Narrow ducts in different components included in the cooling circuit of the cooling system such as for instance ducts in heat exchangers, valves or thermostats, may become clogged by particulate contaminants flowing through the cooling circuit together with the coolant. Such clogging may damage the components and/or impair the functioning thereof.
  • the particulate contaminants may cause increased wear of the components included in the cooling circuit. It is previously known to catch such particulate contaminants by means of a particulate filter arranged in the combustion engine. However, a disadvantage with such a particulate filter is that it may become clogged and therefore requires recurrent maintenance.
  • the object of the present invention is to achieve a new and advantageous manner of removing particulate contaminants from coolant circulating through a cooling circuit of a cooling system.
  • the expansion tank of the present invention comprises:
  • the first inlet basin is configured to receive the coolant which flows into the expansion chamber via said first inlet opening.
  • the first inlet basin is connected to the settling basin by a flow passage, via which coolant may flow from an upper part of the first inlet basin and down into the settling basin, wherein particulate contaminants contained in the coolant received in the settling basin is allowed to settle at the bottom of the settling basin under the effect of gravity.
  • the settling basin is provided with an outlet, via which coolant may flow from an upper part of settling basin and further on towards said lower part of the expansion chamber.
  • the coolant flowing into the expansion tank via the first inlet opening is initially accumulated and spread out in the first inlet basin before flowing from an upper part of the first inlet basin and down into the settling basin.
  • Particulate contaminants contained in the coolant entering the expansion chamber via the first inlet opening cannot settle in the first inlet basin due to the fact that the flow of coolant in the first inlet basin is too turbulent.
  • the flow of coolant in the settling basin is sufficiently calm to enable a settling of particulate contaminants at the bottom of the settling basin under the effect of gravity.
  • particulate contaminants may be removed from the coolant in a simple and cost-efficient manner without having to use any particulate filter that may become clogged.
  • a second inlet opening is arranged in the casing and intended to be connected to a vent conduit of said cooling system in order to allow coolant and air to flow into the expansion chamber via this second inlet opening, wherein the expansion tank is so configured that the coolant entering the expansion chamber via the second inlet opening is allowed to flow to said lower part of the expansion chamber without passing the first inlet basin and the settling basin.
  • the flow passage between the first inlet basin and the settling basin comprises a guide member, here denominated first guide member, which extends between the first inlet basin and the settling basin and along which the coolant is to flow when passing from the first inlet basin to the settling basin, wherein this guide member slopes downwards towards the settling basin.
  • the coolant flowing into the expansion chamber via the first inlet opening is subjected to an initial deaeration in the first inlet basin in that air bubbles rise to the surface of the coolant accumulated in the inlet basin and join the air in the air-filled upper part of the expansion chamber.
  • the coolant is then subjected to a further deaeration when flowing over the first guide member.
  • the layer of coolant formed on the first guide member will be so thin that the air bubbles accompanying the coolant flowing along the first guide member very easily can join the air above the first guide member.
  • the coolant is thereafter subjected to a further deaeration in the settling basin in that air bubbles rise to the surface of the coolant accumulated in the settling basin and join the air in the air-filled upper part of the expansion chamber.
  • the first guide member is flat and slopes downwards towards the settling basin at an angle of 5-15°, preferably 5-10°, in relation to the horizontal plane.
  • the first guide member slopes gently downwards and the flow velocity of the coolant along the first guide member is thereby limited, which is advantageous with respect to the deaeration.
  • the coolant flowing into the expansion chamber via the second inlet opening is subjected to an initial deaeration in the second inlet basin in that air bubbles rise to the surface of the coolant accumulated in the second inlet basin and join the air in the air-filled upper part of the expansion chamber.
  • the coolant is then subjected to a further deaeration when flowing over the second guide member.
  • the second guide member is undulated and has at least one crest which extends perpendicularly to the longitudinal direction of the second guide member.
  • the coolant which flows into the upper part of the expansion chamber via the first and second inlet openings will be directed by the third guide member down into the coolant accumulated in the lower part of the expansion chamber and may thereby slide down into the coolant accumulated in the lower part of the expansion chamber in a rather gentle manner.
