Abstract
A multiblock heat-transfer system including a first heat-transfer unit and at least a second heat transfer unit mounted onto the first heat-transfer unit. The first heat transfer unit contains a first heat-transfer tubular block with at least a first collecting chamber at the side. The second heat-transfer unit contains a second heat-transfer tubular block with at least a second collecting chamber at the side. The first and second collecting chamber each consist of their own collecting pipe, and both collecting pipes are inserted into each other at their front faces and are connected in a fluid-tight manner. In the pipe connection area, the external diameter of one of the collecting pipes approximately matches the internal diameter of the other collecting pipe, and a transverse partition is provided for separating the two collecting chambers.
