DC Centrifugal Fan

     Tell you how to choose a car conditioner cooling fan

  Most people who are familiar with cars know what a car cooling fan is. For the car conditioner, a cooling fan is required. Car conditioner cooling fans are very important. A good cooling fan makes the product reliable and durable. Here are some suggestions for choosing a car cooling fan.

  Choose from product details, a good double ball bearing can reduce friction, can effectively reduce the noise of the fan when it is running, and can improve the internal heat dissipation performance. Regarding the design, the cooling fan can be improved by adopting newer technologies and processes. To better meet the needs of customers, with dust-proof fans, long-term use will not be covered by thick dust and cause poor air circulation. Good materials are also the key, with protection, environmental protection, fire prevention, three-proof treatment, moisture-proof, anti-corrosion and waterproof, etc. Except the car conditioner, car MP3, GPS, car power supply, car air purifier, player, car temperature and humidity control, etc also need the cooling fan.

  The above is a brief introduction to how to choose a car cooling fan . And Xingdong recommend the 200*200*60mm with ball bearing and high CFM 595.00. Specification can be customized according to customer’s require, and also can add the function of dustproof, waterproof. Pls contact us for more detail.

  If you are someone who has always been curious about how car conditioner works, continue reading below for a deeper look

  The air-conditioning system in a car works by manipulating refrigerant between a liquid and a gaseous state. As the refrigerant changes states, it absorbs heat and humidity from the vehicle and allows the system to give off cool, dry air.

  To change the refrigerant between a liquid and a gaseous state, the air-conditioning system works to control pressure and temperature.

  Because automotive air-conditioning systems operate under pressure, they need to remain completely sealed from the surrounding environment. Anything that allows refrigerant to escape or contaminants to enter can cause a failure.

If a leak is present in any component, simply recharging the system with new refrigerant will be at best a temporary fix. Identify the leak, replace the faulty component, and then evacuate and recharge the system.

Not only will a system leak stop the AC system from cooling, it can damage the compressor. The compressor can overheat and damage itself by trying to run with too little refrigerant in the system. Compressors generally are not serviceable and are an expensive item to replace.

  To operate correctly, the AC condenser needs a steady flow of air through its fins. Road debris and dirt may reduce airflow, causing system malfunction. The condenser is mounted directly behind the vehicle grill, leaving it somewhat exposed and at risk for partial blockage.

  This product from Xing Dong company takes into account high quality and good price .

Automotive air-conditioning systems have a few key components. Listed below are the main parts and their roles:

Compressor
Power unit of the system that separates the low-pressure side from the high-pressure side
Takes in low-pressure gas and compresses it into high-temperature/high-pressure gas
Mounted to front of engine and driven by serpentine belt .

Development of industrial cooling fan for new energy passenger cars, brushless fan or standard configuration
In this era of environmental protection, new energy power is gradually becoming the mainstream of development. The operation of new energy buses needs the support of industrial cooling fans. There are different types of industrial cooling fans, so what is better for different types of industrial cooling fans? Brushless fan is becoming a leader
Thanks to the support of national policies, the new energy automobile industry has developed rapidly, which has also driven the product and technical innovation in the field of automobile cooling. As an essential part of automobile cooling system, the performance of automobile cooling fan has also been widely concerned. In terms of how to choose the cooling fan for new energy vehicles, more and more users no longer only value the price. The life, noise, speed, stability, etc. of the cooling fan have become factors that must be considered.
From the perspective of development history, the automobile cooling fan can be divided into three main stages. The first stage: mechanical cooling fan, directly driven by the engine or driven by the pulley; The second stage: clutch fan. The mechanical fan is equipped with a clutch, which can be divided into electromagnetic clutch and silicon oil clutch; The third stage: electronic fan, which controls the running state of the fan through sensors and relays. The three types of automobile cooling fans reflect the development of automobile cooling technology in different periods and the different requirements of users on vehicle performance.
Different types of vehicles have different requirements on the performance of the cooling fan, and their acceptance of the cooling fan technology is different. From the application practice of fans in the traditional fuel vehicle market, the heat dissipation technology of passenger vehicle engines is at the forefront. After 2000, the radiator of passenger car engine began to popularize the electronic fan for heat dissipation. At the same time, commercial vehicles and construction machinery were still belt fans or clutch fans. However, at that time, the radiator fan of the fuel passenger car was still in the brushed electronic fan stage.
Automobile cooling fans can be divided into brush electronic fans and brushless electronic fans. In the service life, the brushless fan is far more than the brush fan. For a long time in the past, due to the high requirements for design requirements, production process, technology research and development, the price of brushless fans was high, and they have not been widely used. However, with the rapid development of new energy vehicles, the gradual maturity of DC brushless motor technology, and the progress of production technology, brushless electronic fans began to “emerge”.
The new energy bus is a subdivision of new energy vehicles with the fastest development and the highest penetration rate. The particularity of urban public transport requires that new energy buses must have high safety, high performance stability, and simple maintenance, which are ultimately reflected in vehicle manufacturing and parts selection. In terms of heat dissipation of new energy bus power system, high-performance cooling fan becomes the first choice.
