ABSTRACT:
Known disk oil coolers, which are surrounded by a plastic covering, require high expenditures during manufacturing because the sealing-off with respect to the front-side connections of the covering must take place by soldering. A pot-shaped housing is disclosed with a lid made of plastic which is welded together and into which, on both sides, sealing devices are fitted for the sealing-off of the stack of disks, in which case the design is such that, after the welding-together, the sealing devices are each prestressed.
