Where is the car radiator fan installed?

Basically, the car at home will be equipped with a cooling fan, which is a device to adjust and solve the internal cooling of the car. Want to know how the radiator fan works? Today, its car editor will briefly introduce the car radiator fan to friends. Let's have a look with the car editor.

Brief introduction of radiator working principle: brief introduction

According to the water temperature and engine load, the signal is transmitted to the computer, and the engine computer adjusts the high and low speed relay of the fan, and also adjusts the relationship through air pressure. The principle is as follows: the air conditioning pressure computer receives signals such as air conditioning pressure switch, indoor and outdoor temperature, and then adjusts the air signal through the bus. At the same time, adjust the pull-in of fan relay. When the air-conditioning pressure is affected by the environment and its relationship with itself increases, the engine computer receives the air-conditioning computer signal, adjusts the suction of the fan high-speed relay, and the fan rotates at high speed.

Brief introduction of automobile cooling fan function: principle

In order to prevent the engine from overheating and ensure the cooling effect, the parts around the combustion chamber (cylinder liner, cylinder head, valve, etc. ) must be properly cooled. The automobile cooling system consists of radiator, thermostat, water pump, cylinder water channel, cylinder head water channel and fan. The radiator is responsible for cooling the circulating water. Most of its water pipes and fins are made of aluminum. The aluminum water pipe is flat and the fins are corrugated. Face up to the heat dissipation performance. The installation target strategy is perpendicular to the target strategy of air activities. Try to achieve low wind resistance and high cooling efficiency.

The antifreeze flows in the radiator core, and the air flows outside the radiator core. Hot antifreeze cools down because it radiates heat to the air, and cold air warms up because it receives heat from antifreeze, so the radiator is a heat exchanger.

(1) Radiator is an automobile cooling system. The radiator in the engine water cooling system consists of three parts: water inlet chamber, water outlet chamber, main board and radiator core. The antifreeze flows in the radiator core, and the air flows outside the radiator core. Hot antifreeze cools down because it radiates heat to the air, and cold air warms up because it receives heat from antifreeze, so the radiator is a heat exchanger.

Ok, that's all for today's car series. As can be seen from the above article, the working principle of radiator fan is still very large. I hope today's brief introduction to Bianxiao Automobile can help my friends.
