1. Cooling fan size

The size of the cooling fan must be consistent with that of the device. Otherwise, the fan cannot be installed. Any equipment design needs to find a professional fan manufacturer consulting information, choose the mainstream size, in addition, such as charging piles, chassis cabinets, energy storage power, cars, security monitoring and other equipment, the size of the use is not the same, according to their own equipment selection, other equipment to use the fan intelligence as a reference

2. Cooling fan noise

The noise of the cooling fan should be as low as possible, otherwise it will affect the user experience.

3. Cooling fan speed

The higher the speed of the cooling fan, the better the heat dissipation effect, but at the same time, it will also produce greater noise. Choose a larger air volume can increase the speed, or choose a thicker, larger cooling fan, strict noise requirements need to mute the case, you can choose multiple fans for heat dissipation, while reducing the air volume of a single fan

4. Air volume of the cooling fan

The air volume of the cooling fan should be large enough to ensure that the heat can be dissipated in time. In addition, the overall design of the equipment and the design of the air duct have an impact.

5. Cooling fan manufacturing materials

The manufacturing material of the cooling fan must be durable, and there will be no quality problems during long-term use. The frame blade is currently used in PA66, PBT, aluminum alloy, PBT and aluminum alloy are the most used, the process is more mature, with wear-resistant anti-seismic anti-embrittlement and other advantages, aluminum alloy is more used in large-size cooling fans. Bearing materials are ball bearings, oil-bearing, long-life oil-bearing, ball bearings because of longer life and stable performance, so the need to choose a cooling fan with ball bearings, the price is more expensive.

6. Cooling fan voltage

The voltage of the cooling fan is generally 12V or 5V, and users need to choose a cooling fan with a suitable voltage according to their own equipment. In addition, the voltage has a certain relationship with the volume of the cooling fan, and the larger cooling fan supports a larger voltage such as 24v and 48v

The selection of a good and suitable cooling fan needs to be matched according to its own equipment and fan parameters, balancing air volume noise and power consumption, so that the equipment can achieve the best working state!
