This paper focuses on a new-type rotating ribbed radiator. Compared with the traditional heat pipe radiator, the device will make fan and fin integrative, which will weaken the thermal boundary layer attached on the fins. Thus, it could avoid the accumulation of dust, then the total thermal resistance of the whole process is reduced and the cooling effect is strengthened, so as to achieve the purpose of energy conservation and emission reduction. 1. Brief introduction of the radiator To solve the problem of the air cooling—the weaken in the thermal boundary layer, we put forward a new-type heat radiating device innovative, that is to say make fan and fin integrative. Through this method, the volume of the radiator could be reduced and the thermal boundary layer is able to be weakened effectively through the optimization design of the blade shape. In the market, the primary wind cooling method is guide heat to fins to increase the heat transfer area, at the same time realize the forced convection heat transfer in the cooling end with fan. In this way, there exists the formation of thicker thermal boundary layer at the end of the fins, which is the main resistance during the cooling process. And the existing wind cooling design own a weaker ability to dent thermal boundary layer, therefore the heat radiating capacity is far behind the theoretical value. Based on the above consideration, the heat transfer process is improved. The heat transfer area is expanded by the phase transformation process on the plate whose heat distribution is even, and it is put in a vacuum cavity. And then the heat is transferred through the lubricating oil, revolving fins, finally the heat is dissipated into air by fins driven by the high-speed rotational motor. The key of the radiator is that all of the thermal resistances are in series, so we can minimize the thermal resistances of each part and the total thermal resistance. The energy saving property could be measured by power consumption, and we can reduce costs through the reasonable selection of materials and structure design. The innovation lies in the combination of fan and fins to reduce the thermal resistance and enhance heat transfer. By modeling and experimental verification, we draw a conclusion that fewer power will be consumed to cool CPU to the same temperature by using the new-type radiator. And the design of rotating blades makes it possible to reduce the ash and to increase the service life.
