The invention relates to a replaceable thermal heating or cooling (RTHC) device for aircraft meal boxes and compartments. In embodiments, the RTHC device includes a housing enclosing a forward control section attachable to a rear thermal section. The housing is slotted for removable installation into rails in the interior walls of a galley food compartment. The thermal section includes gel packs of a heatable/chillable temperature storage medium (e.g., polymer gel) enclosed in a membrane for controlled dissipation and air channels to admit circulating air over or through the gel packs to be chilled or heated by the temperature storage medium. The control section includes scroll fans for drawing air into the RTHC device through air intakes for chilling/heating, exhaust vents for returning the chilled/heated air to the compartment, control switches for the scroll fans, and visual/auditory status indicators, e.g., for fan speed, battery charge, or the interior temperature of the compartment.

    本发明涉及一种用于飞机餐盒和隔间的可更换加热或冷却设备。在实施例中,可更换的加热或冷却(RTHC)设备包括壳体,其包围可附接到后部热部分的前部控制部分。壳体上开有槽,用于可拆卸地安装到厨房食物隔间的内壁中的导轨中。热部分包括可加热/可冷却的温度存储介质(例如,聚合物凝胶)的凝胶包,其包封在膜中以用于受控的消散;和空气通道,以允许循环空气进入或通过所述凝胶包,以被温度存储介质冷却或加热。控制部分包括:涡旋风扇,用于通过进气口将空气吸入RTHC设备以用于冷却/加热;排气口,用于将冷却/加热的空气返回至隔间;用于涡旋风扇的控制开关;和视觉/听觉状态指示器,例如用于风扇速度、电池电量或隔间内部温度。
