With the rapid development of the electronic industry, equipment cooling and cooling systems have become more and more severe. The rise of the cooling fan industry is also an inevitable trend. DC cooling fans have become an indispensable part of electrical machinery and are now on the market. There are more and more branded products of DC cooling fans, and there are more and more manufacturers, but at the same time, they are also mixed with poor quality, which makes people feel at a loss. Let me discuss with you the standard for ordering DC cooling fans. Everyone solves the problem: Criterion 1: 'Brand' generally we will choose branded products, not because of how good the brand is, but a good brand is a guarantee of product quality, because they have their own reputation It is worth relying on and it is also a guarantee for consumers. Standard 2: The DC cooling fan products produced by all businesses in 'Bearings' are divided into two major bearings. 1. Ball bearing. 2. Oil bearing. Features of ball bearing: long life, low noise, oil bearing features: low price. Criterion 3: 'Performance' power-on test, touch it with your hand, feel the vibration amplitude, junk products generally have a large vibration amplitude and are extremely irregular. And the shaft temperature will gradually become higher and the abnormal noise will be louder. Standard 4: 'Noise' The noise level is also one of the factors that determine the quality of the product. When the DC cooling fan has the same size and voltage, the greater the noise, the worse the quality. The above is the order standard for DC cooling fans. The Wenling DC cooling fan manufacturer [Tongchi Auto Air Conditioning] brand merchants specialize in researching and developing DC/AC/booster/bracket cooling fans, which is trustworthy.
