I do not know if dear riders have discovered that there is a very regular horizontal line on the rear window glass of many vehicles. When we touch these horizontally, we will find that this is a sticker that is attached to the rear window glass of the car.
Many riders do not understand the role of this layer of film, in fact, this film is not a trademark of the vehicle, nor is it a vehicle decoration, this layer of film is for the defrost of the vehicle's rear window glass.
In winter, the temperature difference between the inside and outside of the car is generally relatively large. Dear riders in the car will become warmer when they turn on the air conditioner, but outside it will be relatively cold, so it is easy to The car window condenses into a layer of frost, so that the riders can not see the scene outside the car while sitting in the car, but we need to learn about the situation behind the car at any time during the reversing or the course of some driving.
Therefore, when the vehicle is designed, the rear window glass of the vehicle is made into two layers, and with the resistance wire, the frost on the window glass melts and evaporates through the heating of the resistance wire. In this way, dear riders can see very clearly when they look out of the glass behind the car.
These resistance wires consume the electric power in the vehicle's battery when they are heating. Therefore, dear riders must first open the vehicle and then turn on the defogging switch in the rear window glass of the vehicle.
Normally, the defroster will automatically shut down after about 10 to 15 minutes of operation. Dear riders need to pay attention, do not forget to turn off the vehicle defroster. In order to avoid causing damage to our window glass.
In the age of mechanization, we saved physical labor and aggravated mental work.
