The role of the cooling fan under the hood of a car
During the operation of a gas, gasoline or diesel engine, it generates a large amount of heat. Not all of it is converted into kinetic energy of movement. Some of it disperses into the environment. To prevent the engine from overheating, its design includes a system for removing excess heat and engine cooling system fan . A properly tuned system maintains the engine temperature only within a strictly permissible range so that the engine demonstrates maximum efficiency.
Role of the fan in cooling
The water jacket in the design of the cooling system effectively removes excess heat from the cylinder block and directs it to a special heat exchanger. Here, the fluid passes through the radiator honeycomb, coming into contact with air masses, getting rid of excess heat, returning cooled fluid to the engine to restart the cooling cycle. Forced flow is necessary for the following purposes:
- It is idle until the heating exceeds the norm.
- It is practically not involved in the active operation of the motor.
- It turns on automatically from a special temperature sensor.
- Creates a forced air flow through the radiator.
- Does not allow overheating that is dangerous for the power unit.
Unlike fans with permanent mechanical drive from a belt, electric analogues ensure more uniform operation of the motor in a strictly defined temperature range. Coming into operation only when necessary, they do not create a load on the generator or vehicle battery, more details at https://bestauto.com.ua/.
Causes of fan failure
The cooling system of a modern car or truck operates automatically and requires virtually no driver intervention. Breakdowns occur extremely rarely. But, they must be urgently eliminated so that this does not lead to overheating and complete failure of the power unit. The main causes of breakdowns are:
- prolonged operation of the fan with its overheating;
- mechanical damage from foreign objects;
- consequences of a collision during an accident;
- consequences of a collision during an accident;
- li>
- supply of too much voltage to the fan;
- problems with the on/off temperature sensor.
If you correctly select a new cooling fan from a fairly wide range https ://bestauto.com.ua/ventilyator, you can completely restore the car’s reliability and reliable operation of the power unit. Traveling without an electric fan is an unjustified risk that will lead to serious damage to the engine as a whole.
