Working principle of car radiator

The working principle of a car radiator is that coolant flows inside the radiator core, while air passes outside the radiator.

The hot coolant cools down by dissipating heat into the air, while the cold air heats up by absorbing the heat released by the coolant.

When the engine water temperature is high, the water pump repeatedly circulates to lower the engine temperature, achieving the purpose of protecting the engine.‌
