Abstract

Heat is defined as any spontaneous flow of energy from one object to another, caused by a difference in temperature between the objects. Sunlight heats the sheet metal of the car, and it streams in through the windows to heat the interior. It can be affected the air inside the car become very hot and stuffy. Hence, its take times for an air-conditioner to effectively start cooling the passenger compartment on vehicle start-up. Besides, excessive heat can also damage an automobile's interior as well as personal property kept in the passenger compartment. So, a study is conducted to measure the temperature inside of the cars that all directly exposed to the sun, with no major shadows on any of them and activities to choose the suitable apparatus that will be use to develop a device for dissipating heat from a car. The selected car was parked facing sun rise on the free space area (field) with no major shadows on it. Eight different points were measured throughout the four to five hour long experiment. Method of the experiment was to collect temperature every 15 minutes by using a data logger which is connected to a laptop. The data logger used is type USB TC-08 and 8 thermocouple wires were connected to the data logger to collect the temperature rise. Then the experiment was repeated with the device was attached to the car and the result of the experiment was recorded in graph. As a conclusion, this device for heat removal inside a car has been designed so that its function is able help to cooling down the temperature in the car and reduce the excessive heat felt by the passenger of the car on vehicle start-up, besides reduce the damage an automobile's interior as well as personal property kept in the passenger compartment was achieved and successful.
