How much do you know about the long-life cooling oil of the Lions? Welcome everyone to the Lions small class to talk about the long-life cooling oils of the Lions.

1.0 Cooling material: water

The engine cooling system is crucial, and water has advantages and disadvantages

Advantages of water

1. Fast heat dissipation

2. Good liquidity

3. Low-cost configuration is relatively simple

Disadvantages of water

1. The freezing point is high. When the temperature is lower than o ℃, the water freezes to increase the volume. It is easy to cause expansion and cracking of the water tank or cooling system pipeline;

2. Low boiling point, high temperature in summer, when the engine is running under harsh conditions, it will cause the water temperature to rise, or even boil, which will affect the normal driving of the car;

3. The metal salts dissolved in the water form scale after being heated, which reduces the heat transfer efficiency;

2.0 Cooling material: antifreeze

As a cooling material of 2.0, what are the advantages of antifreeze compared to water?

1. It has anti-corrosion function. Since the cooling system of the engine includes several metals such as steel, aluminum alloy, cast iron, copper, and solder used in water tank welding, the antifreeze fluid has long-term contact with these metals, and it must be able to treat all these metals. Protection, the use of deionized water and appropriate additives can prevent all kinds of corrosion.

2. It can prevent the production of scale. Scale is caused by insoluble salts or oxide crystals attached to the inner surface of the cooling system. The main substances that produce scale are calcium sulfate, calcium carbonate, magnesium carbonate, etc. The high-quality antifreeze is made of distilled water and added with anti-scaling additives, which does not produce scales and also has the function of descaling.

3. It has antifreeze function and low freezing point. The freezing point of water is 0℃, and the freezing point of antifreeze can reach -25~-60℃. When parking in the cold winter, it can prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block, and at the same time, it can also ensure that the engine can be started at any time.

4. With anti-boiling function, the boiling point of antifreeze is higher than water. Under standard atmospheric pressure, the boiling point of water is 100°C, while the boiling point of antifreeze is higher than 106°C, which can effectively prevent the engine from boiling.

3.0 Cooling material: cooling oil

What are the major upgrades for cooling oil?

1. Cooling oil has a better freezing point and boiling point. If a small amount of water can be added in the absence of it, it can still maintain a suitable freezing point and boiling point.

2. Cooling oil has good lubricity, but antifreeze liquid does not. Good lubricity has a better protective effect on metal surfaces, water pumps and rubber.

3. The heating capacity of cooling oil and the stability of heat protection far exceed those of antifreeze

4. The long-lasting protection can reduce the frequency of maintenance, especially for the entire cooling system.

5. More luxury cars use cooling oil in the initial installation, such as Ferrari, Lamborghini, Mercedes-Benz AMG, etc.
