What is the role of car pumps?
In the cylinder block of the automobile engine, there is a water channel for circulating cooling water, and a radiator (commonly called a water tank) placed at the front of the automobile is connected through a water pipe to form a large water circulation system, which is installed at the upper water outlet of the engine. There is a water pump that is driven by the fan skin to pump out the heat in the engine block water channel and pump the cold water. There is also a thermostat next to the water pump. When the car is just started (cold car), it does not open, so that the cooling water does not pass through the water tank and only circulates inside the engine (commonly known as small cycle). When the temperature of the engine reaches 80 degrees or higher. When it is turned on, the hot water in the engine is pumped into the water tank, and the cold wind when the car goes forward blows through the water tank and takes away the heat.
