  • Patent number: 9222492
    Abstract: A fluid cooling device (1) as a structural unit has a drive motor (2) driving a rotatable fan impeller (3) and has a storage tank (4) with a filling opening (6) and a fill-level indicator (7). Fluid can be conveyed from the tank into a hydraulic working circuit. In the hydraulic working circuit, the fluid is heated and is cooled via a heat exchanger (5) of the structural unit, and returned into the storage tank (4). The structural unit is designed as a turning assembly in which the filling opening (6) for fluid and the fill-level indicator (7) are disposed on the storage tank (4) such that they can be used and read in a first vertical installation direction (X, Y) of the structural unit, and in a second installation direction (Y, X) inclined with respect to the first installation direction (X, Y), preferably at a right angle.
