Beschreibung
Zusammenfassung:	A heat exchanger (22, 18) includes a heat exchanger shell (36) formed from a first metal material, and a plurality of heat exchanger tubes (38) extending through a plurality of tube openings (46) in the heat exchanger shell (36). The plurality of heat exchanger tubes (38) are formed from a second metal material different from the first metal material. A galvanic isolator (48) is located at each tube opening of the plurality of tube openings (46), radially between the tube opening (46) and the corresponding heat exchanger tube (38) of the plurality of heat exchanger tubes (38). The galvanic isolator (48) is configured to mitigate a galvanic reaction between the heat exchanger shell (36) and the plurality of heat exchanger tubes (38).
