Currently there are many online food delivery services. Customers simply order food via smartphone, the food will be delivered by the service provider. Long delivery times, or when the weather is cold can result in food not being fresh. Recently several studies had been carried out on food delivery boxes that utilize the heat generated from the combustion of motorbikes, where the exhaust gas was channeled directly into the heating chamber inside the box. This design allows gas leaks which can poison food. Therefore, in this research a food delivery box will be developed that utilizes motorcycle exhaust heat with additional fluid. The flue gas does not come into direct contact with the box, making it safer for use in food delivery. The research was carried out by designing two types of prototypes, CFD simulations to analyze heat transfer, to testing. The main difference between the two designs lies in the location of the inlet and outlet. Testing of both designs was carried out at three speed variations, including 10 kph, 20 kph and 30 kph. The experimental results that had been carried out on the first design show that the prototype can work well in keeping the food temperature warm. The simulation results performed on both designs also show good performance. But when compared, the second design is much better than the first design, because it has a better flow distribution.
