What material is the car radiator made of?

Car radiators are made of plastic. The car radiator, also known as the heat exchanger, is a key component in the car's cooling system. Its function is to dissipate heat: the coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket in a continuous cycle. This achieves the effect of heat dissipation and temperature regulation. It is also an important part of the car engine. Below is relevant information about car radiators: 1. The radiator is a crucial component of water-cooled engines, serving as a major part of the engine's cooling circuit. It absorbs heat from the cylinder block to prevent engine overheating. Due to water's high specific heat capacity, the temperature rise after absorbing heat from the cylinder block is not significant. Thus, the engine's heat is transferred through the liquid cooling circuit, using water as the heat carrier, and then dissipated through large-area cooling fins via convection to maintain the engine's optimal operating temperature. 2. When the engine's water temperature is high, the water pump circulates the coolant repeatedly to lower the engine's temperature. 3. High-temperature coolant enters the radiator, is cooled by air, and then circulates back to the engine cylinder walls to protect the engine. In winter, if the water temperature is too low, the water circulation stops to prevent the engine from becoming too cold.
