Free Essays on High Efficiency Cooling Fan For An Automobile

High Efficiency Cooling Fan for an Automobile A cooling fan for a standard automobile provides cooling to the radiator when the forward motion of the automobile isn’t sufficient to do the job. The fan will be connected to the drive shaft of the engine by a belt. There is a bearing in the fan to allow the fan to spin freely during sudden speed changes from the engine. The combustion engine runs more efficiently at higher temperatures, but if the engine gets too hot you run the risk of damaging the engine. The fan helps control the temperature so that the engine stays at a good operating temperature of 190-200 degrees F. The purpose of this report is described below in the design objectives. Design Objectives: 1. Determine the basic design of the cooling fan and all of the factors it will experience during usage. This includes the forces on the fan, usage, the environment, and the maximum and minimum operating conditions. 2. Study and select at least 5 materials for fan manufacture. At the end of the study, select the best material from the five. 3. Consider all factors of each material, including cost, strength, durability, ease of manufacture, and aesthetics. Basic Design of the Cooling Fan The purpose of identifying the basic design of the cooling fan is so that I can determine what materials would have the best characteristics for that design. Depending upon what type of engine and vehicle you are trying to cool, the design may vary from blade size and the number of blades required to cool the radiator. To sufficiently cool the radiator properly the fan must be able to provide a flow of air to the entire radiator. The size of most radiators varies, depending upon the size of the engine and how much coolant has to be passed through the engine. Typically, the bigger the engine, the bigger the radiator. For this report I will assume that we are trying to cool a radiator for a V8 engine. A common radiator...
