From a viewpoint of global warming and heat island countermeasure, development of systems without high-temperature-heat release might be important. Facility development to aggressively utilize solar energy and waste heat under careful consideration on environmental load is important. In case that we make artifacts in place of nature, we should know the nature roles, and should artificially reproduce the necessary roles. Our group calls this kind of engineering procedure as Natural Engineering. Plant leaf doesn’t change solar energy into high-temperature heat, but keeps ambient temperature. It rather lowers ambient temperature because of transpiration. From this point, we are proceeding to develop high-efficiency heat-release system imitating plant transpiration. In this report, we made a new radiator with flat-tube and porous ceramics which has a possibility to discharge lower-temperature heat than the ambient temperature, and the heat-exchanger performance is compared with conventional one. As a result, we found a new flat-tube radiator with porous ceramics outperforms existing flat-tube radiator with corrugate fin.
