<p>An installation for improving the performance of tubular heat exchangers (2), such as surface-type condensers and others, by reducing their flow losses, in which the heat exchanger has several tubes (3) through which a medium passes, and in which a cleaning device (4) is applied to each of these tubes, cleaning its internal surface in a discontinuous manner, in particular having the form of a brush which, at the end of the tube concerned, enters into collector sleeves (1) each having an annular collar (7) for its connection to the end of the tube (5) and another annular collar (6) at its projecting end, the latter collar (6) being inclined in relation to the longitudinal central axis (X) of the collector sleeve (1).</p> |
