<![CDATA[Radiator hoses are generally round and made of polymer rubber. Utilization of this modified hose aims to distribute heat in the coolant to the environment in the hose using a finned pipe so that the heat of the cooling liquid can be wasted with the fins when it is passed, so that when entering the radiator the liquid has a lower temperature. The simulation was carried out using the CAE Ansys Student 2021 R2 software. In this study, water was used as a fluid with an inlet temperature of 360 K, 20 fins, 3 types of fins, namely square, circular, helical and 2 materials, namely aluminum and low carbon steel. The results show that the lowest outlet temperature is in the circular fin with low carbon steel material with a temperature of 348.4 K, and the finned pipe that has a high temperature is the aluminum square fin pipe with a temperature of 359.9 K. There is a change in temperature in each type of fin and material. indicates a decrease in temperature in the flow, this will be very useful and will make the radiator work better because the incoming temperature is lower.]]>
