Oil cooler as heat exchanger plates uses one pipe per disk as conical collar to one side arranged so collars on adjoining disks face one another after half turn round center.

摘要

One pipe of each of the bowl-shaped disks (2) forms a conically expanding collar (16) to one side of the disk bottom and the other disk pipe is designed as a conically tapered collar (17) to the other side of the disk. The two pipes in collar form (16,17) are arranged over the surface of the disk bottom so that after turning 180 deg round the center axis the two collars face one another and their specifically angled cones engage. When each disk has four collars (16,17), these pair up symmetric to the center plane and center transverse plane. The prefered cone angle lies between 8 and 9 deg and the disks have encircling edges (2a) so set back to each side as to partly overlap the edge of the adjoining disk.
