Two new integrated models with heat source–heat sink are established, in which isothermal liquid cooling channels triangle or square sections are, respectively, embedded a cylindrical heating body uniform production. Based on constructal theory, under the conditions of fixed cylinder cross-sectional area and proportion channels, taking dimensionless maximum temperature entransy equivalent therm...

To improve energy efficiency and to recover energy, various mathematical models, such as pinch analysis, entropy exergy entransy have been established analyze heat transfer networks. In this study, these methods were applied the energy-saving effect of epichlorohydrin unit in a certain enterprise. The results showed that when minimum temperature difference (ΔTmin) was 10K, 15K, 20K, efficiencie...
