在第11部分中，描述了电加热器和电冷却器在航天器系统中的使用。 电热控制是获得和维持温度的有效和可靠的方法。固态系统为热调节的控制提供了灵活性，它们能够抵抗冲击和振动，并能在极端物理条件下运行，如高重力和零重力水平。它们也很容易集成到航天器子系统中。购买本文件时可获得的所有当前修订均包含在购买本文件中。

In this Part 11, the use of electrical heaters and electrical coolers in spacecraft systems are described. Electrical thermal control is an efficient and reliable method for attaining and maintaining temperatures. Solid state systems provide for flexibility in control of thermal regulation, they are resistant to shock and vibration and can operate in extreme physical conditions such as high and zero gravity levels. They are also easy to integrate into spacecraft subsystems.All current amendments available at time of purchase are included with the purchase of this document.
