Vacuum-insulated exhaust treatment device with phase change materials and thermal management system
摘要：
A thermally-activated exhaust treatment device, such as a catalytic converter (20) adapted to control exhaust emissions in a vehicle, includes a core having an inner housing (21) and a catalytic material (27) chosen to reduce undesirable emissions from the exhaust of a combustion engine. A jacket includes an outer housing (22) enclosing the inner housing (21) but characteristically not contacting the inner housing (21). The inner and outer housings (21, 22) include walls (30, 31) forming a vacuum-drawn sealed insulation cavity (26) around the inner housing (21). A chamber (60) positioned adjacent the inner housing (21) includes low melting point metal phase change material (61). A thermal management system is operably connected to the insulation cavity (26) that is constructed to control heat flow from the inner housing (21) to maximize the time the catalytic material (27) is within a predetermined optimum temperature operating range or limit catalyst maximum temperature.
摘要（中）：

一种热活化废气处理装置，例如适于控制车辆中废气排放的催化转化器（20），包括具有内壳体（21）和催化材料（27）的芯体，所述内壳体（21）和催化材料（27）被选择以减少排气的不期望的排放 的内燃机。 护套包括封闭内壳体（21）的外壳（22），但特征在于不与内壳体（21）接触。 内壳体和外壳体（21,22）包括形成围绕内壳体（21）的真空拉伸密封绝缘腔（26）的壁（30,31）。 邻近内壳（21）定位的室（60）包括低熔点金属相变材料（61）。 热管理系统可操作地连接到绝缘腔（26），其被构造成控制来自内壳体（21）的热流，以使催化材料（27）在预定的最佳温度操作范围内或者限制催化剂最大值 温度。
