Abstract

This research investigates the effect of a silica (SiO2) nanofluid flow system on the radiator performance function. The initial preparation is to take SEM photos to find out the microstructure. Next, mix the silica nanoparticles with water using a variation of 0.1%, 0.3%, and 0.5%, using a magnetic stirrer, to disperse the mixture, an ultrasound device is used. The liquid that has been separated from the sediment is tested using a series of test equipment consisting of a radiator, flow meter, pump, heater, water tank, and term reader. Data taken is the temperature of the liquid entering and leaving the radiator and the walls entering and leaving the radiator. This research uses 3 variations of fluid flow velocity, namely 2.5, 4.5, and 6 LPM. The result is a decrease in temperature at a fluid flow rate of 6 LPM which is able to release heat to the environment properly. The temperature drop that occurred was 2.5%. then the lowest average radiator effectiveness value at the lowest speed of 6 LPM is 0.905, the highest is at a fluid flow rate of 4.5 of 0.930.

将二氧化硅纳米流体用于汽车散热器冷却系统

本研究探讨了二氧化硅（SiO2）纳米流体流动系统对散热器性能功能的影响。最初的准备工作是拍摄 SEM 照片，以了解微观结构。接着，使用磁力搅拌器将纳米二氧化硅颗粒与水混合，浓度分别为 0.1%、0.3% 和 0.5%，为了分散混合物，使用了超声波装置。从沉淀物中分离出来的液体使用一系列测试设备进行测试，这些设备包括散热器、流量计、泵、加热器、水箱和术语读取器。采集的数据包括进出散热器的液体温度和进出散热器的壁温。这项研究使用了 3 种不同的液体流速，即 2.5、4.5 和 6 LPM。结果表明，当液体流速为 6 LPM 时，温度有所下降，能够适当地向环境释放热量。温度下降幅度为 2.5%。最低流速为 6 LPM 时，散热器的平均效能值最低，为 0.905，最高流速为 4.5 时，为 0.930。
