Abstract (en)
[origin: EP0881452A2] The heat exchanger is made of bundled pipes (1) with their ends mounted in bases. Cleaning springs (8) extend along the interiors of the pipes. One end (9) of each spring is taken out of each pipe and secured to a limit plate (10) at the housing of the heat exchanger (3). It also acts as a mounting for the piston and cylinder units (11) integrated into the housing at the base (4) of a pipe.
