What is the symbol for car coolant?
1 Answers
The symbol for car coolant features two wavy lines at the bottom, representing water, with a thermometer in the middle of the wavy lines. Car coolant is also known as antifreeze, and its full name is antifreeze coolant. Coolant plays a crucial role in water-cooled engines. Functions of car coolant: Winter antifreeze: To prevent the coolant from freezing after the car is parked in winter, which could cause the radiator and engine block to crack, the freezing point of the coolant should be about 10 degrees lower than the lowest temperature in the region, in case of sudden weather changes. Anti-corrosion: If the engine is corroded and perforated, coolant leaking into the combustion chamber or crankcase can cause severe damage. When coolant or water mixes with engine oil, it can produce sludge and gum, weakening the lubrication effect and causing valves, hydraulic valve pushrods, and piston rings to stick. Therefore, a certain amount of anti-corrosion additives are added to the coolant to prevent corrosion of the cooling system. Anti-scaling: The coolant should minimize the formation of scale during circulation to avoid clogging the circulation pipes and affecting the heat dissipation function of the cooling system. High boiling point (anti-boiling): Coolant that meets national standards typically has a boiling point exceeding 105 degrees Celsius. Compared to water's boiling point of 100 degrees, coolant can withstand higher temperatures without boiling (overheating), to some extent meeting the cooling needs of high-load engines.
