Analysis Of The Effectiveness Of The Shell And Tube Type Heat Exchanger As An Oil Cooler With Water As A Cooling Medium
Introduction
The heat exchanger is a crucial device in various industrial applications, including oil cooling systems. In this context, the Shell and Tube type heat exchanger is used to keep the oil temperature within a safe limit. This study aims to analyze the effectiveness of the shell and tube heat exchanger that has been designed, as well as comparing the actual heat transfer rate with the maximum rate that can be achieved.
Background and Literature Review
A heat exchanger is a device that functions to move heat from one fluid to another. In the case of the Shell and Tube type heat exchanger, oil to be cooled flows through the tube, while water acts as a cooling medium that flows through the shell. The method used to calculate effectiveness is NTU -É› (Number of Transfer Units - Effectiveness), combined with experimental testing. This study involves variations in flow and temperature discharge to get accurate results.
Methodology
The research conducted in this study used the NTU-ɛ method to calculate the effectiveness of the shell and tube heat exchanger. The experimental testing involved variations in flow and temperature discharge to get accurate results. The maximum effectiveness value obtained using the NTU-ɛ method is 89.27% in 1.5 liter oil discharge conditions per minute (LPM) with an oil temperature in 60 ° C, 7 LPM water discharge, and temperature Entry water is 27 ° C.
Results and Discussion
The experimental result shows the maximum effectiveness value of 76.79% on the same oil discharge, but with oil temperature entering slightly higher, 61.70 ° C, and water enters at a temperature of 28.39 ° C. From this analysis, it can be concluded that the shell and tube heat exchange device is very effectively used for oil cooling. The oil output temperature obtained from theoretical calculations is 30.54 ° C, while experimental testing shows the output temperature of 36.12 ° C.
Additional Analysis
Analyzing the effectiveness of this heat exchange device is important, especially in industries that rely on oil or lubricants in the engine operational process. An increase in oil temperature can cause a decrease in lubricant capability, which in turn can affect the performance of the engine and the age of the equipment. Therefore, the use of efficient heat exchange devices is very important to keep the oil temperature within the appropriate limit.
Importance of Cooling Media Selection
The selection of appropriate cooling media also affects the performance of this tool. In this study, water is used as a cooling medium. The excess water is its good thermal conductivity and abundant availability. However, factors such as initial temperature, flow discharge, and temperature difference between cooling fluid and cooled fluid play an important role in determining the effectiveness of the system as a whole.
Benefits of Efficient Heat Exchange Devices
Success in designing and operating heat exchange devices can contribute to reducing operational costs and increasing energy efficiency in industrial activities. The implementation of this technology can not only improve engine performance, but also supports sustainability aspects by reducing emissions and hot waste.
Conclusion
In conclusion, the shell and tube type heat exchange device is an effective solution to improve the oil cooling system, providing great benefits for various industries that rely on optimal engine performance.
