Definitions
- the invention relates to a cylinder head of an internal combustion engine having a Coolant jacket, comprising a one-piece cooling jacket core and at least one Ventilation strip.
- the liquid cooling requires the equipment of the internal combustion engine or the cylinder head with a coolant jacket d. H. the arrangement of that Coolant through the cylinder head leading coolant channels, resulting in a extremely complex structure of the cylinder head construction leads. It is the mechanically and thermally highly loaded cylinder head by introducing the Coolant channels weakened on the one hand in its strength.
- the Heat is not sent to the cylinder head surface as in air cooling to be dissipated. The heat is already inside the Cylinder head to the coolant, water usually mixed with additives, issued.
- the coolant is arranged by means of a cooling circuit Promoted pump so that it circulates in the coolant jacket. The to the coolant Heat released in this way from the interior of the cylinder head dissipated and removed from the coolant in a heat exchanger again.
- liquid cooling or a cylinder head with a Coolant jacket comprising a one-piece cooling jacket core and at least one Vent strip, subject of the present invention.
- the cooling jacket core should be integrally formed in distinction to the two or multi-part cooling jacket cores, in which the coolant space through the Arrangement of an intermediate wall in a first and a second Coolant space and, where appropriate, in other coolant spaces, which together in Can be connected, is divided.
- Multi-part cooling jacket cores have tends to have a larger volume of coolant, which is why the warm-up phase of Internal combustion engine takes more time after a cold start, causing the Engine reaches its operating temperature later and emissions, in particular the unburned hydrocarbons, and the fuel consumption are higher.
- a ventilation device or vent strip is an essential and indispensable component of the coolant jacket. Responsible for this are in the essentially two reasons.
- air can enter the coolant circuit from the outside.
- air can enter the coolant circuit from the outside.
- the coolant circuit can when filling the coolant circuit with coolant or admixing of additives for lowering the freezing point of the coolant, which in the Usually, to make the internal combustion engine suitable for winter, unwanted air in penetrate the cooling circuit. But even with leaky cooling circuits, For example, in porous coolant hoses, air can penetrate.
- air in the cooling circuit can cause engine damage d. H. lead to the destruction of the entire internal combustion engine, namely when a Air bubble in the coolant pump, which provide for the promotion of the coolant is, and the coolant pump begins to promote air, d. H. no more coolant is pumped through the cooling circuit.
- the coolant pump stops in a sense, the promotion, so that the coolant circulation to a halt comes and the coolant and ultimately the engine lack of Heat dissipation is overheated and thermally overloaded.
- air Due to their low heat capacity, air can be essential absorb smaller amounts of heat than a liquid d. H. as the coolant. On the other hand, the heat absorbed within the air bubbles due to the poor thermal conduction properties of air are insufficiently forwarded. In addition, air has a lower heat transfer coefficient than one Liquid, which is why the air forms a kind of barrier through which the Heat transfer from the cylinder head or cylinder block to the cooling jacket is worsened. The air that collects at local maxima, the at this Lingering over long periods of time can lead to local overheating at these locations - so-called hot spots - lead. In addition to the low heat capacity, the low heat transfer coefficient and the bad Heat conduction properties of air is mainly due to the lack of Flow is not responsible for convection.
- a venting device is not just for those in the system invaded air, but also for those forming in the system Coolant vapor bubbles or their removal required. Partially evaporated the superheated coolant, which during the boiling process at thedemantelwandung first, the heat transfer from the cylinder head to the Coolant increases before the heat transfer then due to the lower Heat transfer coefficient and the lower heat capacity of the steam reduces d. H. deteriorated. At locations of local cooling channel maxima often form Dead water from areas in which the coolant flow comes to a standstill, thus no heat transfer by convection is given more and evaporation of the Coolant overheating of the cylinder head - so-called hot spots - too are afraid.
- the coolant vapor bubbles can fall below the Vapor pressure implode again and damage to thedemantelwandung lead, which is why you endeavored in principle, the Prevent evaporation of coolant or already formed Dissipate coolant vapor bubbles through a vent before they implode again, thus reducing the risk of damage due to to eliminate pressure waves caused by the implosion.
- the local maxima in the cooling circuit are both in terms of in the circuit Air present as well as in view of the forming vapor bubbles exceed to consider critically, since the bubbles collecting here due to the missing or too weak coolant flow can not be removed.
- the Coolant jacket (2) comprises a cooling jacket core (3), the actual Coolant circuit for heat absorption and removal from the cylinder head, and a Ventilation strip (4) for the removal of air and vapor bubbles from the Coolant circuit.
