IP rating of waterproof DC cooling fan.electric fan Manufacturing

　　Waterproof DC cooling fan is a type of DC cooling fan. It is named because it can protect against water or some fluids. It can be used in some special fields in industrial production. Waterproof DC cooling fans are divided into IP levels. Let us learn more about the IP rating of waterproof DC cooling fans.

　　The waterproof cooling fan is a fan with a high degree of protection. In the harsh application environment (water, salt spray, oil pollution, corrosive gas), heat conduction and heat radiation cannot meet the needs of heat dissipation. XHR fans are required for strong pressure convection heat dissipation, and long-term effective heat dissipation must be guaranteed. The protection requirements of the fans themselves are necessary products; Each insulating paint seal uses a special glue to seal the entire motor part in all aspects.

　　Generally speaking, the waterproof cooling fan on the market generally refers to the cooling fan with the protection level of IP53 and above, and the protection level basically does not exceed IP56, because except for foreign manufacturers, there are only a handful of domestic manufacturers that have the technical ability to achieve IP68 protection for cooling fans. countable.

　　The following will briefly introduce the relevant knowledge of IP protection level:

　　IP is the abbreviation of Ingress Protection. The IP level is the protection level of the electrical equipment enclosure against the intrusion of foreign objects. The source is the standard IEC 60529 of the International Electrotechnical Commission, which was also adopted as the American National Standard in 2004. In this standard, for the protection of electrical equipment enclosures against foreign objects, the format of the IP rating is IPXX, where XX is two Arabic numerals, the first marked number indicates the level of contact protection and foreign object protection, and the second marked number indicates the waterproof protection level , IP is the international code used to identify the protection level IP level consists of two numbers, the first number means dustproof; the second number means waterproof, the larger the number, the better the group leader of protection.

　　The relevant test in my country is based on the standard requirements of GB 4208-2008/IEC 60529-2001 "Enclosure Protection Level (IP Code)", and the conformity assessment test is carried out on the enclosure protection level of various products; the highest detection level is IP68. Conventional product testing grades include: IP23, IP44, IP54, IP55, IP65, IP66, IP67, IP68 grades.

　　The first digit indicates the dustproof index:

　　A system of codes indicating the degree of protection of enclosures against access to hazardous parts by persons, against the entry of solid foreign objects or water, and additional information related to these protections.
