The invention relates to a heat exchanger for temperature controlling and fastening of battery units of the battery of a vehicle. The heat exchanger includes flat tubes that are passable by a heat carrier and a collecting tube and distributing tube for conducting the heat carrier. The flat tubes are established as multi-channel flat tubes. The collecting tube and the distributing tube are connected to each other over the flat tubes so that a holding frame is established that provides a structure forming spaces. The spaces are provided as chambers for accommodating the battery units.
