Solar Powered Exhaust Fan for Automobiles

Long exposure of a vehicle to hot weather at an open space parking will cause an
extreme heat build-up in the car cabin. This extreme heat build-up will increase the
interior temperature of vehicle's cabin which cause uncomfortable situation to most
people, especially when they get into their car. The effect that most of us do not realize
is that this situation will be hazardous to human health and is one of the major causes of
heat illnesses. In order to reduce the high temperature to at least near the ambient
temperature before driver gets into their vehicle, this project will utilize solar energy that
is converted to electrical energy to initiate the fan inside the system. The system also
includes rechargrable battery to activate the fan if there is insufficient energy from solar
f
panel. A relay. concept is used for the switching process and the fan will only activate if
the thermostat detect certain level of temperature. The project scope involved are
' (
studying the negative impact of extreme heat build-up to human health, conducting a
survey to 100 of Universiti Teknologi PETRONAS (UTP) students, analyzing current
product's strengths and weaknesses, designing and fabricating operating exhaust fan and
lastly, validate product by comparing result between sample car with Solar Powered
Exhaust Fan for Automobiles and sample car without the product. The project is
conducted by do the literature review and research, collect data for temperature
distribution in three different volume of cars, produce engineering design specifications,
generate conceptual design, analyze and evaluate alternatives design, finalized design by
producing technical drawing and specifications, construct the prototype and finally,
validate the final product. This solar powered exhaust fan ensures that the engine is not
overburdened and increases its service life, conserving energy, protecting the
environment while creating a comfortable traveling environment.
