<p>A protective wrapping device (100) adapted for shielding a condenser tube (200) of a heat exchanger includes two shell walls (11,12) configured to complementarily mate with each other and to wrap around the tube (200) for heat removal and for preventing formation of water scales on the tube (200). A plurality of tightening members (20,20') are disposed to secure the shell walls (11,12) to the tube (200). When the tightening members (20,20') are released from the shell walls (11,12), the shell walls (11,12) can be detached from the tube (200) for cleaning. <IMAGE></p> |
