<p><P>PROBLEM TO BE SOLVED: To provide a water-cooled heat exchanger having a sacrificial anode installation structure which offers ease of attachment/detachment and excellent sealing performance. <P>SOLUTION: The water-cooled heat exchanger includes: a shell (11) in which a refrigerant chamber and water chambers are dividingly formed; a heat transfer tube arranged in the refrigerant chamber of the shell (11), through which water flows; and a sacrificial anode (31) which is inserted into water chambers (S21, S22) from an opening (32) in the shell (11) and attached to a closing plate (34) closing the opening (32). Between a fixed seat face (33) formed at an outer peripheral portion of the opening (32) in the shell (11) and a closing surface (34a) of the closing plate (34), which faces the fixed seat face (33), a plate-like sealing member (35) in surface contact with the fixed seat face (33) and with the closing surface (34a) is disposed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
