Flow grid for influencing flow of fluid medium e.g. air, in flow pipe of sensor arrangement in internal combustion engine of motor vehicle, has passages arranged such that eddies with direction parallel to flow direction are produced

摘要

The grid (124) has passages (126) comprising an inlet opening (128) at an end and an outlet opening (130) at an opposite end, where fluid medium flows through the passages in a main flow direction (114). The passages are arranged in such a manner that eddies with a rotational direction parallel to the main flow direction are produced, where the eddies are distributed over a cross-section of the grid. Non-planar conducting surfaces are formed in an inner side of the passages and arranged parallel to the main flow direction. A blocking element is arranged at the outlet opening. An independent claim is also included for a sensor arrangement comprising a sensor and a flow grid.
