The invention relates to a heat exchanger for a battery, in particular for a hybrid drive, with connections for the inflow and outflow of a heat exchange medium and with a frame which is connected on both sides with film walls to form a pouch through which a flow can pass, wherein the frame comprises flow guiding elements The invention is characterised in that the frame comprises a separating plate with two parallel lateral surfaces, wherein the separating plate divides the pouch into a first chamber and a second chamber which are delimited in a fluid-tight manner by the lateral surfaces and the respective film walls, wherein in each of the lateral surfaces a channel field of parallel flow channels is formed, the inflow side of which is fluidically connected via a distributor channel and the outflow side of which is fluidically connected via a collecting channel to the respective connections. The invention also relates to a battery with at least one heat exchanger, a vehicle with one such battery as well as a manufacturing method for the heat exchanger.
