The cooling system in a car performs many important functions, without which it would be impossible to provide the drive unit with optimal operating conditions. One of its main components is the car radiator. What does a car radiator do, how does this part work and what are its most important tasks?
The cooling system in any internal combustion vehicle is started as soon as the engine is turned on. Its operation begins by setting the coolant pump in motion, which is responsible for transferring coolant to further parts of the system. It first circulates through a closed circuit without passing through the radiator. Only when it reaches the right temperature due to the extraction of energy from the heated engine does it enter the so-called “large circuit,” which includes the radiator. As a result, it is possible to maintain a stable operating temperature of the drive unit, as well as provide the necessary protection against overheating, which could have very serious consequences.
Cooling system vs air conditioning and electric cars Just keeping the temperature at the right level is not the only function of the cooling system. Other applications of the system are also worth noting. These include the transfer of heat via the heater to the passenger compartment. Thus, the operation of the car's air conditioning and cooling system is to some extent related, although the systems themselves work separately. It should also be noted that the use of air conditioning can put additional strain on the cooling system.
The issue of air conditioning and the temperature of the engine itself is somewhat different in the case of electric cars, where the drive unit does not generate heat. For this reason, such vehicles use specially designed heating and cooling systems. This also means that air conditioning in electric cars is different from the systems used in combustion cars. Its method of operation is mainly based on the use of a special fan heater, although other solutions are often used as well. Car radiator – construction and operation The cooling system in a car consists of several parts, the most important of which is the radiator. It is mounted at the front of the vehicle and is distinguished by a very characteristic structure, which consists primarily of a series of narrow channels – this is known as a water jacket. The fluid that flows through these channels takes excess heat away from the engine.
