Car water tank.
Automobile water tank, also known as radiator, is the main part of automobile cooling system; The function is to dissipate heat, the cooling water absorbs heat in the water jacket, and the heat dissipates after the flow to the radiator, and then returns to the water jacket for circulation to achieve temperature control. It is a component of a car engine.
Working principle
Water tank is an important part of the water-cooled engine, as an important component of the water-cooled engine cooling circuit, can absorb the heat of the cylinder block, prevent the engine from overheating because the specific heat capacity of water is larger, the temperature rise after absorbing the heat of the cylinder block is not much, so the heat of the engine through the cooling water liquid circuit, the use of water as a heat carrier heat conduction, Then through a large area of heat sink in the way of convection heat dissipation, in order to maintain the appropriate working temperature of the engine.
When the water temperature of the engine is high, the pump pumps the water repeatedly to reduce the temperature of the engine, (The water tank is composed of hollow copper tubes. High temperature water into the water tank through the air cooling and circulation to the engine cylinder wall) to protect the engine, if the winter water temperature is too low, this time will stop the water circulation, to avoid the engine temperature is too low.
Main use
The function of the cooling system is to dissipate the excess and useless heat in the engine from the engine, so that the engine can maintain normal temperature operation under various speeds or driving conditions.
The water tank is the heat exchanger of the water-cooled engine, which maintains the normal working temperature of the engine by means of air convection cooling. Once the engine cooling water in the tank boils and vaporizes due to high temperature, when the pressure exceeds the set value, the tank cover (A) overflows the pressure relief, causing the cooling water to decrease and preventing the cooling system pipeline from bursting. Usually driving should pay attention to the engine cooling water temperature gauge pointer on the dashboard is normal. For example, the engine cooling fan failure may cause the engine cooling water temperature to rise or the cooling system pipeline leakage may also cause the cooling water to decrease. Please pay attention to the amount and period of cooling water reduction before adding distilled water.
Operation and maintenance
1, the radiator should not be in contact with any acid, alkali or other corrosive properties. 2, it is recommended to use soft water, hard water should be softened after use, to avoid causing internal blockage of the radiator and the generation of scale.
3, in the use of antifreeze, in order to avoid the corrosion of the radiator, please be sure to use a regular manufacturer and meet the national standards of long-term anti-rust antifreeze.
4, in the process of installing the heat sink, please do not damage the heat sink (sheet) and damage the heat sink, to ensure the heat dissipation capacity and sealing.
5. When the radiator is completely drained and then injected with water, the water switch of the engine block should be turned on first, and when there is water flowing out, it should be closed again to avoid blisters.
6, in daily use should always check the water level, to shut down after cooling water. When adding water, the water tank cover should be slowly opened, and the body of the operator should be far away from the water inlet as far as possible to prevent the high pressure steam from the water inlet to cause burns.
7, in the winter to prevent icing caused by the core rupture phenomenon, such as long-term parking or indirect parking, should be the water tank cover and drain switch, the water all out.
8. The effective environment of the spare radiator should be kept ventilated and dry.
9, depending on the actual situation, the user should completely clean the core of the radiator within 1 to 3 months. When cleaning, rinse with clean water along the reverse inlet wind side. Regular and complete cleaning can prevent the radiator core from being blocked by dirt and affect the heat dissipation performance, and affect the service life of the radiator.
10, the water level meter should be cleaned once every 3 months or depending on the actual situation; Remove all parts and clean with warm water and non-corrosive detergent.
Cleaning tank
Rust and sludge that doesn't form in your engine - can also harm your cooling system. That's why flushing your tank regularly is another important element of vehicle maintenance - something that many hands-on owners often overlook. Your vehicle's cooling system protects itself from heat damage generated by the engine and keeps the engine itself operating within the proper temperature range. Keeping the cooling system free of rust, buildup and contamination will keep it and the engine in good working condition. Fortunately, you don't need to flush your tank as often as an oil change (every 2 years should be enough), and it's very easy to do. Follow the expert step-by-step instructions!
