How to cool your car rapidly after long-time exposure?

After exposure for several hours in the hot sun, many people will immediately open their air conditioner inside the car not knowing that a lot of energy is wasted. Are there other ways to quickly cool your car? We collected several methods widely circulated online, carried on some experiments for each to compare the effect. Here are our experiment results.

To spray the car: ineffective

After exposure, the car can not be cooled by "showers" immediately like a man after strenuous exercise should not take a cold shower immediately. Automotive metal parts have the same thermal expansion and contraction characteristics of the vehicle after exposure, the paint surface temperature will be up to 70 degrees or even higher. When spray the vehicle, it can easily lead to damaging of the paint, the paint chips and other parts. Besides, after high-speed driving, pouring cold water to cool the engine and the tire will directly affect the life of the engine and the tire since their temperature is too high.

Using the sun visor: the most convenient

When the vehicle is parked, placing windshield visors at the front and rear, so sunlight can be prevented that the inside temperature rises slower to achieve the cooling effect. The principle of which is that: the visor usually made of tin foil, its material has a good reflection effect, can block 80% of the solar light. The windshield film at the front and rear can also be considered, its prices are generally over hundreds of dollars.
