An air-liquid heat exchanger assembly (100) for an environmental control system (10) of an aircraft is provided including a heat exchanger configured to transfer heat between air (B) and a liquid (L). The heat exchanger includes a first chamber (110) and a second chamber (120) arranged generally in series relative to a flow of the liquid (L). A movable bypass valve (130) is operably coupled to a controller (140). The bypass valve (130) is positioned between and coupled to the first chamber (110) and the second chamber (120). The bypass valve (130) is configured to control the flow of the liquid (L) through the second chamber (120) and a bypass conduit (146) in response to measured operating conditions of the assembly.
