There are two types of a cooling system in internal combustion engines:
Air Cooling System:
In air kinds of a cooling system, heat that the engine’s outside components reflected is radiated and expelled by the airflow. This airstream is drawn from the atmosphere and is successfully directed by the fins to the engine’s internals. The size of the metallic ridges that make up the fins influences how much heat will always be blown during the procedure.
The overall area of the fin surfaces, the cooling air’s velocity, and the temperatures of the fins and the air being cooled are all factors in air cooling systems. The cooling system is appropriate for engines in small aircraft, cars, motorbikes, scooters, and tractors with less horsepower. Air cooling systems are also used in some small industrial engines.
Benefits of Engines with Air Cooling System:
The advantages of engines with air cooling system are as follows:
- Manufacturing the system is less expensive.
- Due to the lack of water jackets, radiators, circulating pumps, and actual water in the design, it is less in weight.
- little maintenance is necessary.
- There will be no chance of frost damage, such as cylinder jackets cracking or radiator water tubes burst.
- Engines that cool using air are simpler.
Water Cooling System:
Due to their widespread use in car engines, water cooling systems have received most of our discussion thus far. Well, they provide two functions in an engine’s operation, including dissipating extra heat and preventing overheating. Additionally, it keeps the engine at a cost-effective working temperature.
There are four different types of water cooling systems, including:
- Direct or Non-return System
- Thermo-Syphon System
- Hopper System
- Pump/Forced Circulation System
There are two types of vehicle cooling systems, as was already established. The operation of the water cooling system will be covered in this explanation. The system circulates coolant through passageways in the engine block and heads and a water pump. Additionally, it has a thermostat to regulate the coolant’s temperature and a radiator cap to regulate the system’s pressure. Through a network of connected hoses, coolant travels to each of these locations.
Through passageways in the engine block and heads, liquid coolant is transferred through a water cooling system. To counteract the excessive heat produced by combustion, coolant flows from the radiator. A rubber hose transfers the heat from the coolant to the radiator once it has first reached the coolant. Cooling starts as soon as the heated coolant enters the radiator. The air stream entering the engine compartment from the front side of the vehicle provides cooling.
The coolant returns to the engine to complete the same procedure after cooling. The water pump facilitates the flow of coolant into the secret tunnels. To guarantee that the coolant is heated to a specific preset temperature before entering the radiator, there is a thermostat situated between the engine and the radiator. If the thermostat detects cooled coolant, it continues to be close; as a result, the circulation process continues, bypassing the radiator and going back to the engine.
A pressurizing valve is incorporated into the cooling system’s design to stop the coolant from boiling. The radiator cap is made to release pressure if it rises above a certain point because pressure causes the coolant to boil more quickly. If not, too much pressure will destroy the system components like hoses and other parts.
