ABSTRACT:
A heat or material exchanger is provided which comprises a cylindrical housing having a first fluid inlet and a first fluid outlet, an assembly of heat or material-exchange tubes in the housing, partitions securing the opposed ends of the assembly to the housing in a fluid tight seal to partition the housing interior into a first fluid chamber in fluid communication with the first fluid inlet and the first fluid outlet and a second fluid chamber defined in the assembly, a second fluid inlet and a second fluid outlet in fluid communication with the second fluid chamber, an independent spaced defined by the inner wall of the housing and one partition and extending the entire circumference of the housing, but not in fluid communication with the first and second fluid chambers, and a vent in the housing for communicating the space to the ambient atmosphere. When the partition is separated away from the housing, the second fluid enters the space through the gap between the partition and the housing and drains outside through the vent without entering the first fluid chamber. Drainage of second fluid indicates the separation between the partition and the housing.
