Design and development of sucking fan to reduce the temperature inside the car

Abstract

Sucking Fan is a project is that is made for solving heat problems in a vehicle. Objective this project is to design and development Sucking Fan to reduce the temperature inside the car with CAD software, CATIA or Solidwork. Another objective is to study and analysis the temperature inside the car by using Heat Transfer Theory. Besides that to fabricate the prototype system of Sucking Fan. By using this device, heat in the vehicle can be reducing automatically. Sucking fan is function to inhale the warm air in the car when heat sensor detected the high temperature. When the temperature reaches the setting point, the control circuit will activate and the cooling fan will operate to remove the warm air out of the car through a hose that is located below the bonnet of a car. Based on selection have to be done, the good obtained result for design of fan and box body. The design selection for fan is design concept C, the fan have 6 of blades more curve and make it to more sucking heat. For box body of Sucking Fan has been selected because look more ergonomic to located in car cabin. Experiment for testing Sucking Fan to do in 3 days with 2 cars, the cars as a constant to get the heat in car cabin. For the first experiment is to get the heat data inside car without fan for the both car. The second experiment is to get the differences heat data inside car without fan and with 1 fan, for the third experiment is to get the differences heat data inside car without fan and with 2 fans. The result have to be get from the experiment is Sucking Fan can get reduce heat inside car cabin, where in third experiment with use 2 fan operate is more reduce heat inside car compared with 1 fan experiment. The average of differences temperature in car cabin between without Sucking Fan and with one Sucking Fan is 2.05°C. The average of differences temperature in car cabin between without Sucking Fan and with two Sucking Fans is 4.2°C. This average is proving the Sucking Fan function to reduce temperature in car cabin.
