"Micro Cooling Fan" is the gas compression and gas transportation machinery habit of short, commonly referred to include through cooling fan cooling fan, drum fan. Gas compression and gas transportation machinery is the rotation of the mechanical energy is converted to gas pressure and kinetic energy, and gas transportation out of the machine. Scale fan manufacturers generally small nature of their industry, "Micro Cooling Fan" ventilation and air conditioning of large enterprises seldom end in itself, so do heat recovery alone will not be much more business. Due to the size of the new air system manufacturers generally small, there is no scale advantages, is difficult to reduce costs, making the new air system to the low-end residential market promotion difficult. Not only is the scale of production, in the production process, cooling fan industry, there are bottlenecks. But "Micro Cooling Fan" Whether it is for the production of equipment and daily life have played a very important role, so Xin Jian Electronic summary affect the cooling fan in the production equipment plays.
