热管是高效的传热元件,它在我国工业上的应用越来越广泛。热管的经济性可以通过热管的热断(火用)效率来评价。热管吸收的热量和放出的热量相对环境温度都有一定的热(火用)数值。把热管吸收的热(火用)看作是:投入的热(火用),输出的热(火用)看作是受益的热(火用),那么受益的热(火用)与投入的热(火用)的比值就是热管的热(火用)效率。热管的热(火用)效率越高,说明热管的经济性就越好。根据需要的参数设计出来的热管也可以通过热(火用)效率来检查热管的传热性能。
Heat pipe is an efficient heat transfer element, it is more widely used in our country’s industry. The heat pipe economy can be evaluated by the thermal cut-off of the heat pipe. Heat pipe heat and release of heat relative to the ambient temperature has a certain heat (exergy) values. Consider the heat exergy absorbed by a heat pipe as: exergy exergy, exergy exergy as exergy gain, exergy exergy exergy, The exergy ratio is the thermal exergy efficiency of the heat pipe. The higher the heat (exergy) efficiency of a heat pipe, the better the economy of the heat pipe. The heat pipe designed according to the required parameters can also check the heat transfer performance of the heat pipe by exergy efficiency.
