Does the car's cooling fan blow in or out? Do you know? Today, I would like to introduce to you what are the starting conditions of the car cooling fan?
Most of the cooling fans installed on the car are electronically controlled in order to quickly cool the engine. In other words, if the temperature of the engine is high, the electronic control system will start to detect, and then the fan will be turned off. Turn it up and wait for the temperature of the engine to drop, and the electronic control system will stop the operation of the cooling fan.
At the same time, the cooling fan also has high-speed and low-speed distinctions during operation, so as to adapt to a series of different situations that may occur in the engine, so as to ensure the normal operation of the engine.
Since the current cooling fans are all electronically controlled, what are the conditions for starting the cooling fans? How much do you know about the working principle of the cooling fan?
There are two conditions for the cooling fan to start, one is the temperature of the car engine, and the other is the pressure of the air conditioner refrigerant.
The working principle of the cooling fan in the car is: the water temperature sensor in the car engine will monitor the temperature of the engine in real time. When the water temperature of the engine exceeds a certain threshold, the control element will send a start signal to the cooling fan. The same principle is used for air conditioners and refrigerators. The same is that the temperature of the engine is too high to trigger the start.
All in all, the role of the cooling fan is to help the engine to dissipate heat and cool down. According to the body structure of most cars, we found that the cooling fan is behind the front bumper of the engine. This position is easy to use the front bumper brought by the thrust of the car when the car is running. The wind saves the operating power of the cooling fan.
Of course, the cooling fan in the car blows inward, because the car is generally pushed forward, and the air is also passed from front to back. If the electronic fan blows outward, it is not contradictory. The key is that the engine is behind the electronic fan. , without blowing backwards, where else can you blow.
As the technology of cooling fans becomes more and more mature and developed, the requirements for cooling fans will become higher and higher.
