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.
