碩士 === 國立交通大學 === 工學院精密與自動化工程學程 === 101 === The purpose of this proposal is to investigate the influence of the materials of radiators on heat translation. A radiator is one style of heat exchangers, which can be affected by the shapes, the intervals, and the materials of fins. This study adopts the simplest methods to compare the heat translating efficiency of two radiators made of different materials. Sorted by the materials of fins, the experimental radiators can be classified into copper radiators and aluminum radiators. To compare these two materials, pure water, with no ethylene glycol (also known as radiator rust inhibitor), is used as the coolant. Mitsubishi Automobile 1.2 L on the shelf engine is used to eliminate the interference of air convection. The original fans, which are controlled by ECU and negative temperature coefficient coolant temperature sensor, are changed into manual paced electric fans to reduce variables. In conclusion, by diverse experimental methods, this research evaluates the translating efficiency of different radiators using the same equipment.
