Definitions

  • the invention relates to a liquid-cooled cylinder tube of an internal combustion engine, in particular a diesel internal combustion engine according to the preamble of claim 1.
  • the invention has for its object to provide a cost-effective, helical coolant guide around the cylinder barrel of an internal combustion engine with simple means.
  • a helical coolant channel is formed by the helical spring inserted into the cooling gap between the housing and the cylinder tube and fixed in the cooling gap under radial tension.
  • Such a coil spring can be used in any internal combustion engine, the pitch of the turns and the number of turns of the coil spring being easily adaptable to the respective cooling requirements.
  • the coil spring is designed according to the desired heat transfer coefficient.
  • the coil spring lies largely tightly against one wall of the cooling gap and is at a short distance from the other wall. In this way it is ensured that, in addition to the helical flow, an axial partial flow along the cylinder can also be achieved, as a result of which a further increase in the heat transfer coefficient is achieved.
  • the outer diameter of the helical spring is preferably larger than the inner diameter of the receiving bore in the housing, so that the helical spring rests on the housing wall under radial tension. Since the coil spring also has a gap with the cylinder tube, the cylinder tube can be used without hindrance after the coil spring has been inserted.
  • the cross section of the helical spring wire is preferably rectangular, in particular square, with a side wall of the cross section abutting a wall of the cooling gap and thus giving a relatively large contact surface.
  • This cylindrical housing part has a circumferential shoulder 6 in the upper edge for receiving a radially outward-pointing ring flange 4 of the cylinder tube 2.
  • the flange 4 has such a radial extension that between the cylindrical inner wall 8 of the housing 1 and the cylindrical outer wall 7 of the cylinder tube 2 a cooling gap 5 is formed.
  • a helical spring 3 is inserted, the spring wire of which has a rectangular, preferably the square cross section shown in the exemplary embodiment.
  • the coil spring 3 is under radial tension with its turns largely close to the cylindrical inner wall 8 of the housing 1.
  • the sides of the cross section are aligned parallel or at right angles to the side wall 8.
  • the inner surface of the coil spring or its windings is at a distance s from the cylindrical outer wall of the cylinder tube, as a result of which there is an axial partial flow along the cylinder tube.
  • This axial partial flow builds up in addition to the helical flow in the cooling channel between the individual turns of the coil spring 3, which have a distance d from one another, which determines the height of the cooling channel.
  • the convection forced in this way serves the increased heat transfer from the cylinder tube to the flow through Coolant. This increase in heat transfer is particularly advantageous in the case of cooling liquids which have a poorer heat transfer property than water.
  • FIG. 1 has the advantage that the coil spring 3 can be inserted into the cylindrical housing part 1 of the internal combustion engine before the cylinder tube 2 is inserted, and the cylinder tube can be pushed into the center of the coil spring 3 without hindrance, since the inside diameter of the coil spring is larger than is the outer diameter of the cylinder tube 2.
  • the basic design of the exemplary embodiment according to FIG. 2 corresponds to that according to FIG. 1, the same reference numerals being used.
  • the coil spring used in Fig. 2 is under radial tension on the cylinder tube 2 and has a distance s to the cylindrical inner wall 8 of the housing 1.
  • the helical spring in the unloaded state has an outer diameter that is larger than the inner diameter of the cylindrical wall 8 of the housing part 1. 2, the inner diameter of the coil spring in the unloaded state is smaller than the outer diameter of the cylinder tube 2.
  • the distance d between adjacent turns of the coil spring 3 may be expedient to provide the distance d between adjacent turns of the coil spring 3 differently.
  • the distance d in the upper part of the cylinder tube (in the area of the combustion chamber) could be smaller than in the lower area.
  • a helical spring with a progressive pitch, for example, has this course. Through this out education takes into account the greater incidence of heat from the combustion chamber. A greater heat dissipation is thus achieved at the end of the cylinder tube 2 facing the combustion chamber.
