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.

A battery cell assembly is provided. The battery cell assembly includes a battery cell and a heat exchanger disposed adjacent the battery cell configured to cool the battery cell. The heat exchanger has an outer housing. The outer housing defines an interior region and first and second flow guide members. The first and second flow guide members define a serpentine flow path in the interior region. The first and second flow guide members are tilted generally upwardly in the interior region. The serpentine flow path extends from an inlet aperture in the outer housing to another flow path in the outer housing. The another flow path extends from the serpentine flow path to an outlet aperture. The another flow path has a smaller cross-sectional area than a cross-sectional area of each portion of the serpentine flow path such that air bubbles in fluid entering the inlet aperture are urged upwardly through the serpentine flow path and accelerated through the another flow path to exit the outer housing at the outlet aperture.
