The difference between car radiator and car radiator is mainly reflected in the type, composition, working principle, diameter, price and applicable model. Let's discuss it together.
Type : The car engine cooling fan is already standard with an electronic fan, which is electrically driven with a temperature control switch. The truck engine cooling is still the traditional cooling fan, such as engine direct drive fan, belt fan, part of the clutch fan, these are not electronic fans.
Composition : Car engine cooling fan is composed of fan blade, fan hood and motor, the biggest difference is the motor. Truck engine cooling fan mainly consists of roller, fan blade, fan cover, clutch and other components, clutch only exists on the clutch fan.
How it works :
Basic working principle of truck radiator
Coolant cycle : After the coolant absorbs heat inside the engine, it is sent to the radiator through the pressure of the water pump. In the heat sink, the coolant exchanges heat with the outside air, transferring heat to the air, thus reducing the temperature.
Air flow : Radiators are often equipped with fans that speed up the release of heat by drawing in the surrounding air and blowing it towards the heat sink. This process of removing heat through air flow is the key to heat dissipation in a radiator.
Features of truck radiators
Larger heat dissipation area : To cope with the more heat generated by the truck engine, truck radiators often have a larger heat dissipation area to improve heat dissipation efficiency.
Greater durability : Since trucks can work in hardier environments, truck radiators need greater durability and adaptability.
Special coolant : Some special application scenarios may require the use of special coolant to adapt to high temperatures or extreme environments.
The basic working principle of automobile radiator
The function of the automotive cooling system is to keep the car in the proper temperature range under all working conditions. The cooling system of a car can be divided into air cooling and water cooling. Using air as cooling medium is called air cooling system, using coolant as cooling medium is called water cooling system. Usually, the water cooling system consists of water pump, radiator, cooling fan, thermostat, compensation bucket, engine body and water jacket in cylinder head and other auxiliary devices. Among them, the radiator is responsible for the cooling of the circulating water, its water pipe and heat sink are made of aluminum, aluminum water pipe is made into a flat shape, the heat sink is corrugated, pay attention to the heat dissipation performance, the installation direction is perpendicular to the direction of air flow, try to achieve small wind resistance, high cooling efficiency. The coolant flows inside the radiator core and the air passes outside the radiator core. The hot coolant cools because it dissipates heat to the air, and the cold air heats up because it absorbs the heat from the coolant, so the radiator is a heat exchanger.
Diameter : The electronic fan of a car is small in diameter, generally below 20cm. The engine cooling fan of the truck is large in diameter, generally more than 50cm, which is determined by different heat dissipation requirements.
Price : The electric fan of the car is relatively cheap, priced at less than 200 yuan. The price of truck engine fans is higher, including fan blades cheap hundreds of pieces, expensive thousands.
Applicable Model : Car radiators are mainly suitable for small vehicles, while truck radiators are suitable for large commercial vehicles, including all makes and models of trucks.
To sum up, the main differences between truck radiators and car radiators lie in aspects such as their type, composition, working principle, diameter, price, and applicable models
