Effects of Using Nitrile Rubber Foam and Solar Panels on Cover for Cooling Outdoor Sparking Car

摘要

In the summer, the cars are exposed to strong sun when it is parked outdoor without the sunscreen, it has had accelerated the auto parts, interior aging and damage. In order to prevent that exposure, the solutions showed such as car awning, car sunshade and car sunscreen etc…, the above devices showed low effectivity for car sun protection. This paper will study effects of cooling system for outdoor sparking car using solar panels cover. A new covering car with multi-layers structure attaching flexible solar panels were designed to increase effectively sun protection, the nitrile rubber foam divided the light and heat radiation of the sun, the flexible solar panel converted solar energy into electric energy and supplied for the air conditioner to regulate inside car temperature. The results showed that, at nitrile rubber foam layer thickness of 4mm, the car maximum temperature of 41.5°C was observed for solar panel-awning-nitrile rubber cover which is much lower than it is exposed directly by sun radiation and commercial cover. The six solar panels (100W) were adapted on car cover, the solar electric energy supplied enough for a mini air conditioner of 340W. Performance of cooling system using solar panels was also investigated and it showed that the temperature inside car could be down to 24°C.
