The cooling fan is used to force the air supply to the electronic radiator through the wind speed

The first brand of cooling fans, Chengda Electronics is a professional electronic high-tech enterprise integrating R&D, manufacturing, sales and service of brushless cooling fans. The company's production management personnel have eleven years of production technology management experience. The main products are Brushless cooling fan, cooling fan, micro fan, DC fan, AC fan, DC blower

The cooling fan is used to force air supply to the radiator through the wind speed to meet the needs of the engine for moderate heat dissipation. From the perspective of the working form of the cooling fan, there are three control methods for the cooling fan. Which three are they? Let's take a look at it together Let's go:

One is the mechanical drive control method suitable for large vehicles and heavy vehicles;

The second is the self-control electric control method that has nothing to do with the engine ECU and independently monitors the environmental parameters;

The third is a comprehensive intelligent control method that integrates various parameter information such as engine, air conditioner, compressor, and vehicle speed.

The former mainly uses the principle of mechanical transmission. Either directly driven by the engine crankshaft, or driven by the engine belt to drive the cooling fan; the latter two only reflect the real engine cooling fan control technology.

From the cooling fan drive control module, the cooling fan control technology can be divided into two categories:

One is the centralized control that focuses on the control of the engine power system control module;

The second is a split control that is independent of the engine or has a communication connection with the engine. Centralized control means that the control of the cooling fan is performed by the engine powertrain control module that has various control functions such as fuel injection, ignition, emission, air conditioning, and cooling fan of the engine. It is coordinated and dispatched by it to ensure the good power, economy and emission of the engine.

Split control means that it is separated from the engine, and the external electronic control module is used to drive the fan, so as to achieve the purpose of the cooling system to make the engine moderately dissipate heat. This external electronic control module is what we call the engine cooling fan controller. Various fan control types and control technologies have their own characteristics. Large car manufacturers take what they need according to different situations, so various control technologies coexist at present.

Chengda takes the high standards in the industry as the starting point, takes quality as the market, takes the market as the guide, relies on talents, and takes service as the win-win" idea - is becoming a new star in the cooling fan supply industry, and is constantly developing and growing. , equipment investment continues to increase, and it is our responsibility to meet the development needs of the cooling fan industry. Welcome new and old customers to call, visit, guide and negotiate, we will adhere to quality, firm integrity, adhere to service and work together with people from all walks of life to create a new era of Chengda Electronics!
