ABSTRACT:
A demountable connector assembly for a modular heat exchanger permits individual modules to be removed and replaced without replacement of the entire heat exchanger core. As applied to heat exchanger modules of conventional tube and header construction, an end chamber on each end of the module has a thin flexible wall which allows axial extension of the module when it is installed between parallel inlet and outlet header surfaces to obviate the imposition of damaging stresses on the soldered connection joints between the heat exchanger tubes and the header plates. The mounting assembly also allows the headers to be temporarily sealed while a module is removed to allow continued operation of the heat exchanger until a replacement module can be installed.
