    • In an engine cooling system, an upper coolant chamber (31) and a lower coolant chamber (24) of a typical engine (10), such as an internal combustion engine or fuel cell, are formed adjacent to the heat-emitting components of the engine (14, 27), and a substantially anhydrous, boilable liquid coolant having a saturation temperature higher than that of water is received within the engine coolant chambers (24, 31). A coolant expansion reservoir (76) defining an expansion chamber (80) is coupled in fluid communication between the engine coolant chambers (24, 31) and the engine's ambient atmosphere for receiving coolant from the engine coolant chambers and permitting coolant flow between the expansion chamber and engine coolant chambers with thermal expansion and contraction of the coolant. The expansion reservoir (76) is mounted within a desorption environment (90) formed within the vehicle's engine bay on the exhaust side of the radiator (54) for heating the coolant within the expansion chamber (80) to a temperature at or above a predetermined temperature during a substantial period of engine operation in order to vaporize substantially all water from the coolant and thereby maintain the coolant in a substantially anhydrous state.
    • 在发动机冷却系统中,与诸如内燃机或燃料电池的典型发动机(10)的上部冷却剂室(31)和下部冷却剂室(24)形成为邻近发热部件 发动机(14,27)和具有高于水的饱和温度的基本上无水的,可蒸发的液体冷却剂被接纳在发动机冷却剂室(24,31)内。 限定膨胀室(80)的冷却剂膨胀容器(76)在发动机冷却剂室(24,31)和发动机的环境大气之间流体连通地联接,用于接收来自发动机冷却剂室的冷却剂,并允许冷却剂在膨胀室 以及具有冷却剂热膨胀和收缩的发动机冷却剂室。 膨胀容器(76)安装在形成在散热器(54)的排气侧的车辆的发动机舱内的解吸环境(90)内,用于将膨胀室(80)内的冷却剂加热到等于或高于预定的温度 在大部分发动机运转期间,为了使来自冷却剂的所有水基本蒸发,从而将冷却剂保持在基本无水状态。
