Car radiator is the main parts of the car cooling system; its function is to distribute heat, cooling water in the water jacket to absorb heat, flow to the heat sink after the heat dispersed, and then back to the water jacket and the cycle continued. So as to achieve the effect of cooling thermostat. It is also an important part of the car engine.
Radiator is a car cooling system, the engine water cooling system in the radiator from the water chamber, the water chamber and the radiator core and other three parts. The coolant flows in the radiator core and the air passes through the radiator core. The hot coolant is cooled by cooling the air and the cold air heats up by absorbing the heat dissipated by the coolant, so the radiator is a heat exchanger.
Use and maintenance
1, the radiator should not be in contact with any acid, alkali or other corrosive properties.
2, the proposed use of soft and hard water to be softened after use, to avoid the internal heat block and scale generation.
3, in the use of antifreeze, in order to avoid corrosion of the radiator, be sure to use regular manufacturers and in line with national standards of long-term anti-rust antifreeze.
4, in the installation of radiator process, please do not damage the radiator (film) and bumps radiator to ensure the cooling capacity and sealing.
5, the radiator completely re-water and then water, the first engine block to open the water switch twist open, when the water out, and then closed, so as to avoid blisters.
6, in daily use should always check the water level, to stop cooling after the water. Add water, the water tank cover slowly open, the operating staff should be as far as possible away from the water nozzle, to prevent high pressure steam oil spout caused by burns.
7, in the winter to prevent freezing caused by the phenomenon of core, such as long-term parking or indirect parking, the water tank cover and the water switch, the water will be released.
8, spare radiator effective environment should be kept ventilated, dry.
9, depending on the actual situation the user should be 1 to 3 months on the radiator for a complete cleaning of the core. When cleaning, rinse with water to the side.
10, the water level gauge should be cleaned every 3 months or depending on the actual situation, the parts removed with warm water plus non-corrosive detergent cleaning.
Automotive radiators are generally divided into water-cooled and air-cooled. Air-cooled engine cooling is to rely on the flow of air to take away the heat in order to achieve the effect of cooling. The outside of the cylinder of the air-cooled engine is designed to form a dense sheet-like structure, thereby increasing the heat dissipation area to meet the cooling requirements of the engine. Air-cooled engine compared to the use of the most water-cooled engine is light weight, easy maintenance and so on.
Water cooling is the tank radiator is responsible for cooling the coolant with the engine temperature; the task of the pump is to allow the coolant in the entire cooling system circulation; fan operation using the ambient temperature directly blown to the radiator, making the radiator high temperature The coolant is cooled; the thermostat controls the coolant cycle to store the coolant.
When the vehicle is running, dust, leaves, debris is easy to remain on the surface of the radiator, blocking the heat sink results in the radiator performance. In this case, we can use the brush to clean up, you can also use high-pressure air pump blow away the debris on the radiator can be.
