Zusammenfassung:	The invention relates to a heat exchanger for a battery unit, comprising coolant-conducting tubes (3b) which end at both sides in in each case one collector (3a, 3c), wherein each collector (3a, 3c) is connected to at least one tube (3b) and a potential equalization element for electrical potential equalization connects at least one collector (3a, 3c) to a housing (5) of the battery (2). To produce potential equalization between the heat exchanger and a battery housing in as inexpensive a manner as possible, the potential equalization element (14, 15, 17, 23, 24) and the collector (3a, 3c) are formed in one piece.
