Abstract (en)

[origin: DE19711591A1] The invention relates to a fluid cooling device in the form of a modular unit having a motor (10) which drives a ventilator wheel (2) and a hydraulic pump (14) which takes fluid from an oil reservoir (16) and delivers it to a hydraulic work circuit (18) which heats the fluid and sends it to a heat exchanger (20), from whic h the fluid returns, cooled, to the oil reservoir (16). The coil reservoir (16), being shaped like a trough and surrounding at least part of the motor (10) and the hydraulic pump (14), and having high walls (24) in the manner of a half-shell, results in a relatively high-volume oil reservoir which is nonetheless a part o f the fluid cooling device with a compact, space-saving structure, due to the fact that it at least partially contains parts of said fluid cooling device, thus saving space.
