how solar- vehicle ventilators work - solar powered car air freshener

Solar mechanics-
The most striking aspect of a solar car ventilator is the way they use solar energy to operate on their own.
Their power supply is free and will never go away forever-
In any case, in our lifetime.
In order to utilize the energy of the sun, these devices rely on a series of photovoltaic (PV)cells.
Photovoltaic cells work through photoelectric action. What's that?
Light particles from the sun or other bright sources--
Called photon. -
Peel the electrons out of the photovoltaic medium (usually silicon) of the solar cell.
Some of these loose, energetic electrons power the device through the circuit.
On their return trip through the circuit, these are now canceled
Electricity-powered electrons can do one of two things: they can repeat the process if there is a strong sun;
Alternatively, if the sun disappears and stops supplying photons as fuel, they can precipitate into available silicon molecules [1 [

In typical solar car ventilation, a set of solar cells is connected to a small, lowvoltage fan.
This fan moves the air while the tiny vents send out the hotter air and guide the colder air into your car.
Normally, the entire exhaust unit is suspended on a long gasket
Just like the material hanging from the top edge of the window during installation.
The micro solar panels and fans themselves fit very well with the interior window glass
Away from the elements and curious passers-.
A standard measure of the potential cooling capacity of the fan is the amount of air it can move over a given time period, usually expressed as cubic feet per minute (CFM).
A solar car ventilation equipment manufacturer claims its products exchange air in the car about every 20 minutes.
If we take a typical car like Toyota Camry, it has an internal passenger space of 101 cubic feet, which is about 5 cubic feet for a solar fan.
In contrast, a pluginin, three-speed, 16-
The diameter of the Oscillating desktop fan is inches and moves between 1,300 and 1,700 CFM.
With these solar energy
Electric gadgets, it's a little unrealistic to expect to return to the Ice House
90-cool car interior onPlus degree day;
However, it is reasonable to expect a cabin that is not as hot as it was.
Also, as some suppliers have mentioned, fans can keep enough air flowing to evacuate the bad smell that often thrive in the hot and humid environment of sealed cars.
If you're the kind of person who forgets to take smelly sneakers or uneaten fast food from the car, one of these devices may save you from a bit of embarrassment when a friend comes for a ride.
Of course, the technology is not perfect.
It does have its weaknesses.
