The invention "relates to a water pipe cooler, in particular for internal combustion engines of motor vehicles, in which between water pipes inserted with their ends in end bottoms sickgackförraige gwlschenlanellen provided and with which on both sides one formed by pipes and larvae Kühlnetses arranged Seitenbleehe with the Bndboden through a Schraelresr connection are connected »As a fast connection a welded or brazed joint is preferred «

In known Wasaerrohrkühlern the side plates with a frame clamp part or lower water tank and an upper one Water tank connected The lower frame part and the side panels can be attached erefc * if the end floors with the Waseerkäster assigned to them. connected are »This is a thing a cumbersome and expensive manufacture.,

The invention is intended to achieve, that the two end = · bb'don are always arranged at the same distance and the water = pipe cooler has a great rigidity. This is invented

This results in a closed, riser Radiator association, which always has the same block height and which is _{very resistant to stresses "ZoB e} twisting force", because of the connection of the intermediate. lamellas with the side plates are adjacent to these plates.
