What is the purpose of an automotive air conditioning blower?
2 Answers
The function of an automotive blower is to distribute the cold air from the air conditioning evaporator or the hot air from the heater core into the vehicle interior. Below are some details about automotive blowers: 1. The blower primarily consists of the following six components: motor, air filter, blower body, air chamber, base (also serving as an oil tank), and oil drip nozzle. 2. The blower operates via an eccentrically mounted rotor inside the cylinder, where the changing volume between the vanes in the rotor slots draws in, compresses, and expels air. 3. During operation, the pressure difference within the blower automatically delivers lubrication to the oil drip nozzle, which drips into the cylinder to reduce friction and noise while preventing gas backflow. This type of blower is also known as a sliding vane blower.
As a car enthusiast who has tinkered with cars for years, I think the car's AC blower is truly crucial. This thing is essentially a fan installed in the air conditioning system, with its main job being to push air flow: when you want to cool down, it blows air over the cooling component, letting the cold air rush in; in winter when warmth is needed, it helps push hot air through the heater core. It's not just about temperature regulation—it's also super important for safety, like quickly defogging the windshield on foggy days for clearer visibility. I remember once on a long trip when the blower broke down, the AC completely failed, and the car became as stuffy as a steamer, significantly increasing driving risks. During regular maintenance, pay attention to blower noise or weak airflow—it might be due to dust blockage or motor aging. Periodic cleaning can keep it running smoothly.
