• the known fluid cooling device can only be sold as a complete structural unit, consisting of the combination of filter, pump, cooling and tank unit, and in particular retrofitting to existing oil tanks or tank units with the other unit is hardly possible. Since these tank and oil tank units often come from other manufacturers and are already on site, it would be desirable, depending on the respective application, to retrofit such units with a unit consisting of a filter, a pump and a cooling unit, or if necessary, carry out conversions such that the one fluid cooling device is replaced by a new one, for example with a higher output, and the respective container or tank unit remains at the place of use.
• the known solution relates to a fluid cooling device with a cooling, filter and pump device combined in one structural unit, in which fluid conveyed by the pump device in a fluid circuit can be filtered by the filter device and cooled by the cooling device, and wherein the filter device has at least one when contaminated interchangeable filter element.

• the solution according to the invention has a compact structure and can be easily replaced by a new one, for example such a unit with greater performance, should this become necessary.
• An energetically favorable operation of the overall assembly also benefits from the fact that the cooling unit opens into the interior of the medium of the tank unit to be cooled, so that the medium cooled down can be passed on to the tank unit directly via the cooling unit. In this way, there is also a homogeneous temperature situation inside the tank unit, which enables a defined fluid removal via the pump unit.
