What is the function of car radiator?
The function of the car radiator is to store water and dissipate heat. The radiator is the main part of the cooling system, the purpose is to protect the engine from damage caused by overheating. The principle of the radiator is to use cold air to reduce the temperature of the coolant from the engine in the radiator. The radiator belongs to the automobile cooling system. The radiator in the engine water cooling system is composed of three parts: the water inlet chamber, the water outlet chamber, the main fin and the radiator core. The radiator cools the coolant that has reached a high temperature. When the tubes and fins of the radiator are exposed to the airflow generated by the cooling fan and the airflow generated by the movement of the vehicle, the coolant in the radiator becomes cold.
In order to avoid overheating of the engine, the parts around the combustion chamber (cylinder liner, cylinder head, valve, etc.) must be properly cooled. In order to ensure the cooling effect, the automobile cooling system generally consists of a radiator, a thermostat, a water pump, a cylinder water channel, a cylinder head water channel, and a fan. The radiator is responsible for the cooling of the circulating water. Its water pipes and radiating fins are mostly made of aluminum. The aluminum water pipes are made of flat shape and the radiating fins are corrugated. Pay attention to the heat dissipation performance. The installation direction is perpendicular to the direction of air flow. The wind resistance should be small and the cooling efficiency should be high. The coolant flows in the radiator core, and the air passes outside the radiator core. The hot coolant becomes cold by dissipating heat to the air, and the cold air heats up by absorbing the heat radiated by the coolant, so the radiator is a heat exchanger.
Car radiator installation location
Most car radiators are installed in front of the engine and the fan. Its function is to increase the heat dissipation area and accelerate the cooling of the coolant. In order to take away the heat from the radiator as soon as possible, a fan is installed behind the radiator to work with the radiator.
Working principle of car radiator
The working principle of the car radiator is based on the water temperature, engine load, and the signal is transmitted to the computer. The engine computer controls the fan high and low speed relays. At the same time, it is also affected by the air conditioning pressure. The air conditioning computer receives the air conditioning pressure switch, indoor and outdoor temperature, and other signals, and then passes the bus Send the air conditioner signal to the engine computer, the engine receives the signal that can be turned on, controls the compressor, and at the same time controls the fan relay to pull in. When the air conditioner pressure is increased by the environment and its own influence, the engine computer receives the air conditioner computer signal to control the fan's high speed The relay is closed and the fan runs at high speed.
The heat generated when driving a car is enough to destroy the car itself. Therefore, a cooling system is installed on the car to protect it from damage and keep the engine in an appropriate temperature range. The radiator is the main part of the cooling system, the purpose is to protect the engine from damage caused by overheating. The principle of the radiator is to use cold air to reduce the temperature of the coolant from the engine in the radiator. The radiator has two main components, the radiator fin composed of small flat tubes, and the overflow tank (on the upper, bottom, or both sides of the radiator fin).
Car radiators should be cleaned regularly
The role of car radiators in car devices is more than just heat dissipation. Here is a reminder to everyone, when cleaning the condenser cover of the water tank with a high-pressure water gun, do not rush to the engine, because nowadays cars are equipped with an electronic control fuel injection system, and the engine compartment is equipped with an engine computer, a gearbox computer, and an ignition computer. And various sensors and actuators. If it is flushed with a high-pressure water gun, there may be a short circuit, which may damage the engine computer.
