【 Chassis radiator cooling fan 】 The choose and buy of practice
Our company is the Wen ling chi automotive air conditioning 】 Is specializing in the production of radiator cooling fan, dc cooling fan, dc fan, cooling fan manufacturers, more than ten years production experience of Taiwan enterprises, access to different customers, now the cooling on the problem of the purchaser in the purchase of the cooling fan is lost, for them to find a suitable ratio of don't know how to assess standard, after all, good heat dissipation of the cooling fan poor light appearance is not completely come out, below is our company's many years of experience, sincere hope to help you. Specific summarized as the following: the first: purchasing case radiator cooling fan, first of all, to determine the type and appearance, you want to determine the voltage, bearing, line length, volume, speed, current, noise, etc. General frame's material is aluminum and gold, leaf is made of PBT. Procurement of dc cooling fan plain box and is made of PBT material. Second: to get the radiator cooling fan first look at its trademarks voltage, ( Ac voltage can be divided into 110 v, 220 v, 380 v. Can be divided into 5 v dc voltage is 12 v, 24 v, 48 v. ） , avoid the wrong voltage of radiator cooling fan burned, cause bad effect of chassis cabinets. Third: the trademark is the upper bearing ball or oily, ball is a sign of HB, oil is the sign of the HS, have 3 - ball 50000 hours of life, only 1 - oil The life of 30000 hours. Fourth: the power cord is also very important, if the power cord is peel welding place with copper wire or not exposed, then don't use, will cause harm to people, the consequences will be electrocuted. Fifth: see a radiator cooling fan's quality is good, still depends on the cooling copper wire of the cooling fan and stator, ( Copper wire is pure copper wire, copper clad aluminum, moreover have iron copper clad, the stator is pure steel and steel belt) Copper wire and stator quality directly affects the life of the radiator cooling fan, good copper wire and stator can improve the speed. If poor copper wire and electronic will directly affect the use time of chassis cabinets. Sixth: general cooling temperature at minus 20 - the cooling fan Between 80 degrees, humidity from 20% 85%. Beyond this range can select box leaves are aluminum and gold material of heat cooling fan. Seven: radiator cooling fan if there is a noise in operation, oil bearing words may be shifted without oil or the cooling fan inside the stator, maybe the ball ball bearing is bad, or ball falls off the lid, or the cooling fan inside the stator shift. Eight: suddenly turn radiator cooling fan in the operation, the most likely is the cooling fan blades has been burned, it is possible that the voltage wrong ( After the beginning of the 220 v, 110 v will turn, etc. 10 - After 30 minutes will automatically turn) , it is possible that the radiator cooling fan inside copper wire broken, can also be the power cord. Above is the practice case the choose and buy of radiator cooling fan, chassis cabinets manufacturers can choose according to these requirements. More about this knowledge, can at any time consulting us. We are possessing 【 YiRongChuan 】 Electronics co. , LTD. Sincerely hope everybody to be able to purchase the right products, can cooperate with purchaser has a sincere pleasure.
