Does the number of cooling fan blades of the miner have anything to do with the air volume?

The current cooling fans for mining machines have many molds, and the number of blades is also confused by the customer's design or use. Is it better to use a cooling fan with more blades, or one with fewer blades? In fact, the air volume of the cooling fan has no equal relationship with the wind pressure and the number of blades. However, at the same speed, the air volume with more blades will generally be larger, but the blades with more blades generally do not rotate at a high speed. , The speed will be lower. For example, the 12038 is a commonly used cooling fan for mining machines. The 11-blade air volume and pressure are 230CFM, 27.5mmH2O, and the speed can only reach 4300 rpm. The 7-blade model has the air volume and pressure 241CFM, 31.3mmH2O, but the speed is 6200. turn. From this point of view, the air volume and pressure of the 7-blade are a little bit larger than that of the 11-blade. The above two models have a high utilization rate in the mining machine industry, and the cost of the 11 blades is lower. Therefore, the usage is larger. The air volume and pressure data of the two cooling fans are very similar. Therefore, from this point of view, the number of blades is not a decisive factor in determining the air volume.
