Types of engine cooling fans

When the engine to burn fuel generated high temperature (2200 ° C). Benefiting the engine of about 35% of this heat to move the car. The rest must get rid of him redundant as heat (because they lead to the engine) damage, as well as when to get rid of excess heat more than required plus the engine cooling occurs and leads to an increase in fuel consumption and engine capability and the erosion of the engine parts.
The engine cooling system functions:

1 – maintaining the operating temperature of the engine.
2 – get rid of excess engine heat.
3 – quick access to the operating temperature of the engine.
4 – contribute to the process of heating car.
Types of engine cooling system:
Engine cooling system, engine cooling water

1 – air cooling system
2 – Water Cooling System
Work for cooling water system theory
It works by force of coolant around the cylinders and areas of friction. The move heat from the hot parts of the coolant which applies to the radiator, where the air that passes through the radiator fluid to carry heat and disposal works. And then back again to the liquid flow around cylinders, and so on.
Parts of the engine cooling water system
1 – coolant Coolant

Coolant features (water)
1. available and cheap
2 – glides easily
3 – absorbs heat well
4 – There is no seriousness in dealing with him

Defects coolant (water)
1 – freezes at zero degrees Celsius
2 – leads to steel metal parts
3 – evaporates
4 – left engine deposits

To reduce the disadvantages of the use of water is added to liquid water to prevent freezing Ethylene glycol 50% of the composition of the coolant.
And it advised to use contraceptive freezing in the summer, where he was working to raise the boiling point of the water temperature as it prevents rust and corrosion.

2 – Shirt Water Water Jacket

A passes within a block and cylinder head surrounded near the cylinders and combustion chambers places cavity, pass out water to absorb heat from the hot parts.

3 – irradiated (radiator) Radiator
Which is the main part of the cooling system with water, a place in which you get rid of the heat from the coolant to the air. It also works for the coolant reservoir.
And prove irradiated often in front of the car in front of the engine in the face of outside air to assist in the cooling process.
Irradiated parts
1 – duct cooling pipes (middle part): Made of pipes and cooling fins.
2 – reservoirs (top and bottom): used to store the liquid.
3 – filling neck is the upper reservoir is used for radiocarbon full and closes the radiator cover and has a place to install the overflow pipe.
4 – Exchange valve: is the lower reservoir of the radiator to dump radioactive liquid.
5 – Oil cooler: heat exchanger in one of the radiator tanks and cars that started the gears Automatic Fund.
Theory irradiated work or Ridatir
Explain Ridatir, exits Ridatir, engine cooling system, engine cooling water

Irradiated heat Kmpadl works where heat moves from hot part (coolant) to the cold portion (air). During the engine left the hot coolant from the engine to the tanks radiator made of copper or aluminum tubing run a fast heat conduction metals and transmitted heat from the liquid to the pipes and cooling fins and into the turbulent flow as it passes through the tubes, where reduced temperature of the liquid before he returned again and fins to the engine to get rid of another amount of heat.
Different types of radiant
There Tsamaman rife for radiant by way of entry into force of the liquid inside them

1 – vertical flow
2 – horizontal flow
4 – the radiator cap Radiator Cap
Functions radiator cover
1 – cover the neck of the radiator fill hole to prevent coolant leaks.
2 – Raise the system pressure to increase the temperature of the boiling liquid.
3 – to allow the discharge of excess pressure and dislocations system.
4 – closed system allows the fluid in the radiator to move in and out of the surplus tank (Bagpipes).
Radiator cover components

1 – interlace Sticky rubber or metal cover for your love liquid and air pressure
2 – pressed by the valve disc Baay loader to close the neck is full to increase pressure system to raise the boiling point of the liquid temperature.
3 – Valve dislocations, a small valve allows the bottom of the cover of the liquid return from the additional reservoir

to the radiator when the cooler coolant temperature mid.
Action radiator cover theory
Riding on the neck of the radiator is full of slot cover where Alahabk works to love the pressure and the fluid within the system, work pressure valve cover to raise the pressure as that would lead to the lifting of coolant temperature to 125 ° C. When you continue to increase the temperature fluid pressure rises from the LED pressure value and lead to open the valve and then pressing to push the liquid through a tube surplus surplus tank, and that radioactive fillings and mechanisms to protect it from damage.
When the low temperature of the liquid below the liquid and the air system size and therefore arent here dislocations valve opens to allow the liquid reference of the surplus to the radiator tank composed. This protects the system from collapsing under atmospheric pressure effect.

5 – tank surplus or Bagpipes Overflow tank
Overflow tank connects Palmha surplus through a tube and is made of clear plastic reservoir and has external signs to determine the liquid level. And that’s where the cooling system is closed, the lack of air entry increases the cooling efficiency, it also helps not to be rust and reduces the corrosion rate.
When the hottest rushes engine coolant from the radiator to the overflow tank when the liquid cools down once again to the radiator. And it can detect the coolant level by observing the liquid level Balqrbh. And compensate for the lack of liquid Basafh liquid directly to the bagpipes.

6 – Water Pump Water Pump

Water pumps, engine cooling system, engine cooling water

Water pump to pump cooling by means of centrifugal force, and the engine fitted with an introduction and working through the course of taking the movement from the pulley mounted on the crankshaft.
The installation of a water pump

1 – the pump blades: a disk of metal with feathers or fins to push the liquid.
2 – the pump column: a column of iron up the movement of the blades to the hub of the pump the pump.
3 – interlace the pump: prevents coolant leakage between the pump shaft and the pump housing.
4 – bearings: bushing wear or pomegranate helps to pump shaft rotation to stay overnight.
5 – Hub pump: provide a place to install a hoop pump and fan.
6 – The pump housing: Made of cast iron or aluminum and represents the pump body.
And installing filler between the engine and the pump housing to prevent coolant leaks.
7 – mechanisms Hoses

Lei transporting radioactive coolant from the engine to the radiator, and be flexible to withstand vibrations. Mechanisms relevant links to prove their own through Alagafiz.
Elly Upper: up between the radiator and thermostat housing complex located clouds or head of cylinder
Lower Elly: up between the entrance to the water pump and radiator, and Inside the Lower Elly Yai prevents adhesion where it is exposed to this who is shaken by the withdrawal of the pump.

8 – lei heating system
Thermostat, thermostat in a circle cooling
It has a diameter smaller than the other mechanisms and up coolant to warmer

9 – thermostat or a thermostat Thermostat

Valve is working heat and controls the validity of the coolant to the radiator to maintain the heat of the engine. There is often the bed thermostat thermostat, which is located between the engine and the radiator upper Elly.
Installing the thermostat
Consists of a cylinder filled with a waxy substance with a piston In normal mode LED will be closed under the influence Yai pressing the plunger.
Action thermostat theory
When heated coolant expands waxy material inside the cylinder and it pushes the piston against the forces of Elá opening the valve. At low temperature shrink waxy material within the cylinder, leading to the expansion of Elá to close the valve. When closing the valve left coolant through the Affiliate Link, and without this link there will be no homogeneity in the coolant temperature thermostat will not be able to sense the rise in the temperature of the liquid.
This link can either be internal (within the water shirt of the engine) or external through my private specifications to withstand the heat and high pressure.
Values ​​run Thermostat
Thermostat works when the temperature of the Code of him and be in the range of 82-91 ° C.
10 – Cooling Fan Cooling Fan
The fan works to draw air through the radiator fins air and pass the tubes on the engine to get rid of excess heat. The fan lead to increasing the volume of air flowing through the radiator to assist in the speed and efficiency of heat exchange. And it shows the importance of the work of the fan when the rotation of the engine while the vehicle is stopped, as well as at high engine temperature.
The engine does not need to be refrigerated at a rate high at the beginning of the operation, where the engine temperature is still low. It is also at high speeds can be sufficient to quickly rush of air as a result of the speed of the car, and the propeller need to be bigger to run at high speeds energy as a result of air resistance to the movement of the fan blades.
Types of propeller

Divided by mode of management:
1 – mechanically operated fan: to take the movement of the crankshaft through the fan belt, proving the fan hub on the water pump pulley. In some cases, placed between the pump and the fan and keep the link to bring the fan of the radiator.
2 – electrically operated fan: to take their movement through the electric motor takes the necessary energy by electrical wires connected to a battery. This type user in the engines used in the payment front of the browser engine.
Replacing the Fan

1. propeller blades: Blades solid fixed angle blades and a soft carrying angle with speed.
2 – clutch of the fan (speed-sensitive): Works with fluid and often rides the mechanical fan is where the task of the fan blades with soft feathers.
3 – clutch fan thermal (heat-sensitive): often riding on the mechanical fan with a double metal is sensitive to heat Yai. And controls this Elá in oil into force within the clutch. When the slow-speed sliding clutch does not spin the fan, and at the hottest engine loves clutch revolves fan.
4 – Electric motor: operates the car battery Sticky Composite cage on the radiator is used with electric fan. And it controls the work of the electric motor thermal switch when the engine is cold be the key non-conductive do not operate the fan, and at high temperature becomes a key in the operating mode and operating the fan.
Fan air Radiator Shroud prompt
Made of plastic or sheet helps the fan to draw air through the radiator. Sticky irradiated so that the rear surrounds the space surrounding the fan.

11 – Sir pump Belt
Water pump rotates through a flexible workflow and who is at the same time transfer of traffic to many special engine accessories.

Types of belts:
1 – Sir shaped V: Sir allocates one transmission to one extension of the engine accessories.
2 – the conduct of his ribs problem-shaped V: Sir dearly used one to move to the privacy of all engine accessories. This is common in modern cars where he needs to place less and transmits traffic more efficiently.
12 – Heat shown Temperature Indicator
Heat is shown Bthbloh car to alert the driver in the event of overheating.
It consists of
1 – heat or bulb warning or heat meter and a warning lamp counter.
2 – sensor (sensor) thermal prove Baklawoz jerseys water of the engine.
13 – heating system Heater System
It is considered part of the cooling system drive. Hot coolant passes through the mechanisms and control valve to the radiant heating small slot located inside the board itself, which separates between inside the car and the engine. Air rushes into the car through the radiant heating where heat gain is working on passenger heating, and there is a mobile portals can be controlled air for mixing cold Balsachen to control the temperature inside the car.
