Low Noise DC fan pressure and air flow are two relative definitions. In general, DC radiator fan in manufacturers to save costs under consideration, to design cooling fan air volume, but also give up some air pressure. If the cooling fan can push a lot of gas flow, but the wind pressure is small, the wind can not blow on the bottom of the heat pipe radiator. That is to say, some of the working speeds are very high and the air volume is quite large. But that is to say, the actual effect of heat pipe cooling is not very good. Conversely, the higher the wind pressure, the smaller the air volume is usually There is not enough air-conditioning and radiator to carry out heat exchanger, will also lead to heat pipe actual effect is not very good. I enterprise low noise DC FAN WELCOME YOU TO BUY! The following three heat transfer methods are indispensable to all types of heat pipe radiator, but the emphasis is different. 1. Convective heat transfer: heat transfer by which a fluid fluid mechanics (gas or liquid) carries off the subtropical zone In the heat pipe system software of the computer host, the forced convection heat transfer method of heat pipe cooling is more common. 2. Radiant heat: refers to the use of radiation sources to transmit heat, usually the most common means of solar radiation. These three heat pipe heat transfer methods are not isolated, in normal heat transfer, the three heat pipe heat transfer methods are all produced separately, mutual effect. 3. Heat conduction, convective heat transfer and radiant heat. The transfer of kinetic energy is called heat transfer, and it is the most widespread method of heat transfer, either by itself or when a chemical is in contact with a chemical. For example, the method by which the CPU radiator base immediately touches the CPU to remove heat is referred to as heat conduction. For example, the General Cpu air-cooled Radiator Fan, CPU radiator and CPU surface immediately touch, CPU surface heat according to heat transfer to the CPU radiator; The direct current electric radiator fan causes the cyclone to take heat from the surface of the CPU radiator according to the convection heat transfer, while the flow of the gas in the main cabinet takes heat from the gas around the CPU radiator according to the convection heat transfer Up to the outside of the main cabinet; another part of the overall high temperature will produce heat radiation to the lower part of the surrounding temperature. The heat transfer rate of the raw materials of the heat pipe radiator, the heat capacity of the raw materials of the heat pipe radiator and the material of the heat pipe radiator, and the reasonable total area of the heat pipe radiator are all related. What are the disadvantages of DC radiator Fan determinism? The most common way is to use axial fans (that is, the most extensive type of Fan) downwind, due to the comprehensive good use and low cost. If the axial flow fan in the opposite direction, it will become upward exhaust, in some very model specifications of radiator will choose this kind of way. The difference between the two exhaust modes depends on the cyclone mode. When the air is sprayed, the air is turbulent and the wind pressure is high, but it is easy to be damaged by friction resistance. In basic theory, the heat dissipation efficiency of turbulent flow is much higher than that of Laminar flow, so it has become a popular design method. Axial Fan, although widely used, but also has a definite disadvantage. Axial fan by motor parts of the block, cyclone can not flow Shenzhen Manufacturers Custom DC fan 9225 ball bearings, cold-resistant LED detection of aging box radiator fan smooth, manufacturer Wholesale AC radiator Fan 220V 110V ball bearing moisture proof DC welder radiator fan 8038H TTP:
