Abstract

The research aims to evaluate the engine rotation (rpm) against changes in radiator temperature. Radiator used is compact heat exchanger tube and fins type. The study was conducted using an experimental method on a BMW E.36 car with a stop state. The research scheme we use consists of radiator water reservoir tanks, water pumps, and radiators. Measuring instruments used are anemometer, thermocople, stopwatch and reader. Data retrieval is carried out at the radiator entrance temperature, radiator exit temperature and the temperature on the radiator wall that hits the fan. In this study we did variations of engine rotation (rpm) of 1000, 1500, 2000, 2500 and 3000 rpm. The results showed that in the use of fans at a speed of 6.5 m / s able to throw heat into the environment well, this proved to be obtained the highest temperature value at the 10th minute of 57.5 oC at a fan speed of 3.5 m / s. Meanwhile, in the 10th minute the lowest temperature was obtained from a speed of 6.5 m/s of 40 oC.

Abstract

This study aims to evaluate the effect of fluid flow rate on the effectiveness of radiator performance by using nanofluid consisting of a mixture of raw water with nano silica (SiO2) particles. The research was initiated by testing the silica material morphologically using a Scanning Electron Microscope (SEM) with the aim of knowing its microstructure. Next, mix the silica nanoparticles (SiO2) with water using a ratio of 0.5%, processed using a magnetic stirrer for 8 hours and precipitated for 24 hours. After being separated from the sediment, the nanofluid was tested for performance using a series of cooling system performance test equipment. A series of test equipment consisting of a radiator, flowmeter, water pump, pipe installation, heater and reservoir tank. Research data collection was carried out at the inlet and outlet temperatures as well as the radiator wall. In this study, variations in fluid flow velocity of 2.5, 4.5, and 6 LPM were carried out. The results showed that the decrease in temperature with the use of a fluid flow rate of 6 LPM was able to dissipate heat well to the environment. The decrease in temperature that occurs is 2.5%. Meanwhile, the lowest average radiator effectiveness value at the lowest speed of 6 LPM is 0.905, the highest at a fluid flow rate of 4.5 is 0.930.

Abstract

This paper reports on community service activities carried out by the Politechnic Indonusa of Surakarta team foreign exchange reserves. Devotion is focused on the members of the cadet reef who have graduated from school that aim to provide knowledge and skill regarding repairs and maintenance of air conditioning (ac) cars. Through this program, it is expected that participants will be better prepared to open jobs in the service areas. This devotion begins with theoretical delivery, consisting of basic component materials and an automobile - conditioned mechanical system. Materials are delivered by methods of speech, discussion and question-and-answer. Participants are given understanding on how the components work, unloading the tides, checking damage, cleaning and trouble shooting on car ac units. The training was followed by 22 participants. The results of this training, being able to provide skill and understanding in the repair of car air conditioning, make it possible for participants to start their own businesses especially in the proper and proper areas of care and car ac repair.
