A method is disclosed for cleaning the shell side of the core of a heat exchanger formed of a set of tubes passing through transverse plates which include two end plates and at least one baffle plate. A hole is first formed in an end plate in a region between core tubes. A lance is next inserted into through the hole and used to jet the section of the core between the end plate and the first baffle plate. A boring tool inserted through the hole in the end plate is then used to drill a hole in the baffle, allowing the cleaning process to be repeated for further sections of the core. |
