In order to avoid overheating to ensure the cooling effect, parts of the combustion chamber (cylinder liner, cylinder head, valve, etc.) must be properly cooled. Car cooling system with the individual by the radiator, thermostat, water pump, cylinder waterway, cylinder head waterways, fans and other components. The radiator is responsible for the cooling of the circulating water. Its water pipes and heat sinks are made of aluminum. The aluminum pipes are made of flat shape. The heat sinks are corrugated and face the heat dissipation. The installation of the standard is perpendicular to the standard of air. May be able to do a small wind resistance, cooling efficiency is higher.
Coolant activity in the radiator core, the air in the radiator core through the process. The hot coolant is cooled by cooling the air and the cold air heats up due to the heat dissipated by the coolant, so the radiator is a heat exchanger.
The role of car radiator
Radiator is a car cooling system, the engine water cooling system in the radiator from the water room, the water chamber, the main film and radiator core composed of three parts. Coolant activity in the radiator core, the air in the radiator core through the process. The hot coolant is cooled by cooling the air and the cold air heats up due to the heat dissipated by the coolant, so the radiator is a heat exchanger.
The radiator also serves as a water vapor and heat dissipation, with an air vapor valve on the car radiator cover and a common air hole connected to the atmosphere. When the water temperature rises, the cooling air in the car radiator expands and the water vapor pressure rises, and the steam valve is hit. When the water temperature drops, the pressure drops and the air valve opens, and the outside air from the public Stomatal into the radiator, so as to ensure that the radiator pressure unchanged.
In the operation should ensure that the public stomatal smooth, can not plug or lose its function, otherwise it will affect the radiator and engine cooling performance. The radiator inside the cooling water is not pure water, but by the water, antifreeze and a variety of specialized use of preservatives composed of assimilates, also known as coolant. The coolant in these coolant content of 30% to 50%, forward the boiling point of the liquid, under the working pressure, the car coolant agreed to the working temperature of up to 120 degrees Celsius, beyond the boiling point of water and not easy to evaporate The
Zhenjiang New District Leisure Electronic Radiator Factory developed and manufactured radiator series products, widely used in AC and DC, regulator switch, communication, purification, frequency, inverter and other power areas, and fluorescent electronic ballasts, audio equipment , Power amplifier circuit, knot knives, automatic control instruments, electronic products.
Reasonable selection and proper use of profiles Radiator components are designed to meet the requirements of electronic product design and are also part of improving the life of the power devices.
With the rapid development of science and technology, making the power of components continue to increase, the volume gradually reduced, rapid increase in heat flux density. So it is extremely important to solve its cooling problem, the rational choice and proper use of the insulator radiator components, is to improve the life of the power device to improve the assembly of the machine shows a great advantage.
