Tongchi miniature waterproof cooling fan manufacturers teach you how to identify high-quality automotive cooling fans in the material supplier

The editor of Tongchi miniature waterproof car cooling fan manufacturer tells you that car cooling fans are currently an electronic parts industry that will not decline, and cooling fan manufacturers are also everywhere, and the quality is of course uneven. Therefore, the editor of the Tongchi miniature waterproof car cooling fan manufacturer tells you that if you want to buy a high-quality car cooling fan, you need to identify the quality of the cooling fan from two aspects, one is whether the parameters of the car cooling fan meet the standard, and the other is the car cooling fan. Whether the material of the shape is high quality. However, the editor of the Tongchi miniature waterproof car cooling fan manufacturer knows that the parameters can be tested, but the material aspect needs a professional appraisal to see. Here, the editor of the Tongchi miniature waterproof car cooling fan manufacturer teaches you how to correct it. Identify high-quality automotive cooling fans from their appearance. u003cbru003e u003cbru003e u003cbru003e 　　 1. There are aluminum alloy and plastic on the frame of the car cooling fan, but generally the aluminum alloy is used on the AC car cooling fan, and the DC car cooling fan is made of plastic (17251 DC The fan frame is aluminum alloy). But even the frame of the same aluminum alloy is thick and thin. Moreover, the central shaft in the aluminum alloy frame is very important. Good car waterproof cooling fan manufacturers use copper central shafts, and poor cooling fans generally use aluminum alloy materials. u003cbru003e u003cbru003e u003cbru003e 　　2. Circuit board: The editor tells you that good cooling fan circuit boards are more complicated, and the materials used are of course comparable at a glance. There are many small parts and poor heat dissipation. There are few fan parts, and it feels very simple. u003cbru003e u003cbru003e u003cbru003e 　　3. Copper wire: Tongchi miniature waterproof car cooling fan manufacturer tells you that the copper wires of good cooling fans are relatively rough and strong, using manual winding methods, while the copper wires in poor cooling fans are all Very thin, of course only for the same product comparison, the smaller the fan, the thinner the copper wire. u003cbru003e u003cbru003e u003cbru003e 　　4. Wire: Tongchi miniature waterproof car cooling fan manufacturer tells you that the wire inside a good cooling fan is composed of many thin wires intertwined together, quietly forming a thick wire, and the poor wire is only one, very thin ,simple. u003cbru003e u003cbru003e u003cbru003e 　　 5. Rolling balls: This one introduces more, just remember, the rolling balls are much better than the oily ones. Regarding the identification of the quality of the ball, Tong Chi micro waterproof car cooling fan manufacturer has also introduced. u003cbru003e u003cbru003e u003cbru003e 　　6. The material of the fan blade: It is also easy to distinguish. The stator of a good cooling fan is generally a steel stator, which is very strong.
