The Cooling System Of The Engine

Let's start with the condenser on the far left, as hot coolant passes through the condenser, the temperature becomes lower. The cooling of the condenser is to increase the contact area with the air to cool down, so the condenser looks dense.

After the cooling forehead coolant flows around the engine cylinder under the action of the pump, at this time, the piston in the cylinder is constantly doing piston movement, friction heat, gasoline combustion heat. When the coolant flows through the cylinder, the cylinder temperature decreases, but the coolant itself rises and the coolant becomes hot.

While the pump is still working, the coolant is being pushed into the condenser as it gets hot, and in the process, the coolant meets the thermostat, which controls the flow. If the flow rate is low, then the coolant needs to be "baked" around the cylinder for a little longer. If the flow is high, the coolant can pass through quickly, but it will get slightly hotter.

After passing through the thermostat, the hot coolant enters the condenser and the coolant becomes cool again.

It's a cycle that doesn't seem to stop.

The pump is constantly moving the coolant in one direction. When the coolant enters the inside of the engine and sees the cylinders, it becomes hot, flows out of the engine, and enters the condenser and becomes cold.

Through such a cycle, the coolant makes the hot engine less hot. Therefore, the engine is cooled by coolant.

Of course, this is a well-designed, complexly manufactured system.

The main components of the fan, pump, thermostat, condenser, wind, and the void outside the engine cylinder make up the cooling system and support the coolant to transfer heat inside and outside the engine.

The earliest coolant was water

But because water tends to freeze in winter and tends to boil when it is overheated.

So most of them are using coolant now. Coolant does not freeze in winter, and it is less likely to boil than water, although it will always boil.

If there is no coolant in the cooling system, the cylinder will become hotter and hotter, just like if you put the pot on the stove and keep burning, the cylinder will deform, the piston movement will be blocked, and eventually either the piston will die or the cylinder will die.
