要約

This paper describes the application of Heat Transfer Technology with Phase Change Inhibited (HTTPCI) to a new kind of Integrated Heat Deriving And Radiating Devices (IHDARD). IHDARD presented in this paper is a unique, thin plate type, foldable, rib-free structure with inner mini-channels in network. An infra-red thermal imager and thermocouples are used to measure and examine the temperature distribution on the device surface and the heat transfer performance of the device. From its temperature characteristics to its excellent performance of heat transfer, including high heat flux and high heat transmitting rate, all exhibits obvious advantages of IHDARD compared with traditional heat radiating devices. The innovative design philosophy for IHDARD is briefly described, which overturns some traditional concepts on heat radiator design. The preliminary theoretical thinking of the authors on the mechanism of heat transfer behind the Heat Transfer Technology with Phase Change Inhibited is presented. Its successful application to the heat radiation of high-power LED has demonstrated that it has potential to provide excellent solutions for tough problems of heat transfer. Finally, it is indicated that the discovery of the new heat transfer mode corresponding to Heat Transfer Technology with Phase Change Inhibited has enlightenment to both the development of next generation of heat transfer devices and the research of heat transfer as a science discipline.
