Metal materials show poor lifetime behavior under high‐temperature conditions and aggressive atmospheres. An alternative solution is the use of ceramic material, e.g., silicon carbide ceramics. These ceramics cannot be processed and joined like metal materials. For this reason, the simple geometry of a heat pipe can be used as a basic design for ceramic heat exchanger systems in the high‐temperature process technology for industrial and power plant applications. Heat pipes are hermetically sealed tubes filled with a working fluid. By transferring heat to one side and by releasing heat from the other side a two‐phase cycle is set up. For these apparatuses a numerical calculation model for a more exact determination of the working behavior of large units under high‐temperature conditions is introduced, considering both convective and radiative heat transfer.

高温应用陶瓷热管换热器的计算方法

金属材料在高温条件下和侵蚀性气氛下表现出较差的使用寿命。另一种解决方案是使用陶瓷材料，例如碳化硅陶瓷。这些陶瓷不能像金属材料一样进行加工和连接。因此，在工业和发电厂应用的高温工艺技术中，热管的简单几何形状可用作陶瓷热交换器系统的基本设计。热管是充满工作流体的密封管。通过将热量传递到一侧并从另一侧释放热量，可以建立一个两相循环。对于这些设备，引入了用于更精确地确定大型设备在高温条件下的工作行为的数值计算模型，
