Abstract
Official abstract text for this publication.
The invention relates to an apparatus for supplying a coolant to a closed fluid circuit, preferably for an exhaust gas cooler of an internal combustion engine of a motor vehicle, comprising a connecting stub, wherein the connecting stub is designed for insertion into a coolant connection, wherein a flow-directing device, which is of projection-like design, for the coolant is integrated in the interior of the connecting stub.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for supplying a coolant to a heat exchanger comprising a connecting stub, wherein the connecting stub is designed for insertion into a coolant connection, wherein a projection-like flow-directing device for the coolant is integrated in an interior of the connecting stub, wherein the flow-directing device is formed approximately centrally on an inner wall, in a manner projecting into an interior of the connecting stub, and a contour of the flow-directing device runs in a direction of longitudinal extent of the connecting stub in a manner rising in a direction of the heat exchanger, wherein the contour of the flow-directing device is of mirror-symmetrical design in a radial direction of the connecting stub, wherein a respective curvature adjoins the inner wall of the connecting stub on both sides with respect to a centrally formed maximum. 2. The apparatus according to claim 1 , wherein the connecting stub is designed as a plug and seal element. 3. The apparatus according to claim 1 , wherein an axial rise of the contour of the flow-directing device runs linearly in the direction of the heat exchanger. 4. The apparatus according to claim 1 , wherein an axial rise of the contour of the flow-directing device in the direction of the heat exchanger runs at least in accordance with a power function. 5. The apparatus according to claim 4 , wherein the axial rise of the contour of the flow-directing device runs parabolically. 6. The apparatus according to claim 1 , wherein the respective curvature runs concavely from the maximum of the flow-directing device to the inner wall of the connecting stub. 7. The apparatus according to claim 1 , wherein a radial orientation of the contour of the flow-directing device is determined depending on a width of a block of the heat exchanger. 8. The apparatus according to claim 1 , wherein the connecting stub has a circular or round cross section and is inserted in the coolant connection.
