Working principle of automobile radiator Working principle of automobile cooling system

Car radiator, as the name suggests, "heat dissipation" is its most critical function. As the heat transfer and heat conduction parts inside the car, the car radiator plays a crucial role in the car. The key material of the automobile radiator is aluminum or copper, and the radiator core is its key component, which contains antifreeze. Generally speaking, car radiators are heat exchangers. Next, let's take a look at the working principle of the car radiator with the car editor at this station.
The working principle of car radiator 3354 radiator introduction

A radiator is a car cooling system. The radiator in the engine water cooling system consists of three parts: inlet chamber, outlet chamber, motherboard and radiator core. The antifreeze flows into the radiator core, and the air flows out of the radiator core. Hot antifreeze becomes cold because it radiates heat to the air, and cold air becomes hot because it absorbs the heat of the antifreeze, so the radiator is a heat exchanger.

Working principle of automobile radiator - radiator principle

To prevent the engine from overheating, parts around the combustion chamber (cylinder liner, cylinder head, valve, etc.) Must be properly cooled. In order to ensure the cooling effect, the automotive cooling system is mostly composed of radiator, thermostat, water pump, cylinder water channel, cylinder head water channel, fan and so on. The radiator cools the circulating water. Its pipes and heat sinks are mostly aluminum. The aluminum pipe is flat and the fins are corrugated. It focuses on heat dissipation. The installation direction is perpendicular to the airflow direction, so that the wind resistance needs to be small, and the cooling efficiency needs to be maximum high.

The antifreeze flows into the radiator core, and the air flows out of the radiator core. Hot antifreeze becomes cold because it radiates heat to the air, and cold air becomes hot because it absorbs the heat of the antifreeze, so the radiator is a heat exchanger.

Automobile radiator is an indispensable component in automobile water-cooled engine cooling system. Now, it is moving in the direction of lightweight, high efficiency and economy. The structure of car radiators may not necessarily adapt to new developments. The most common structural forms of automotive radiators can be divided into two types: direct flow and cross flow.

The core structure of the radiator generally has two kinds of tube and tube. The core of the tubular radiator is composed of many thin cooling tubes and fins, and the cooling tubes mostly adopt oblate cross sections to reduce air resistance and increase the heat transfer area. The radiator core should have enough circulation area to allow the antifreeze to pass, and there should also be enough air circulation area to allow enough air to pass and take away the heat transferred to the radiator by the antifreeze.

Radiators play an irreplaceable and vital role in auto parts, and maintenance is essential. At the same time, there must be sufficient heat dissipation area to complete the heat exchange between antifreeze, air and fins. The tubular radiator is made of corrugated cooling strips and cooling pipes welded alternately. Compared with the tubular radiator, the tubular radiator can increase the heat dissipation area by about 12% under the same conditions. In addition, the dispersion zone is provided with turbulent louver holes, which destroy the adhesion layer of flowing air on the surface of the dispersion zone and improve the heat dissipation capacity.
