Cooling of the cooling fan repair inverter is how to protect the cooling fan
When the cooling fan abnormal heat dissipation, such as not to turn, the noise is big, we want to find out, but how to open, first to separate oil bearing rotor and stator and double ball bearing of the radiator cooling fan, as long as the card ring down, the leaves can take out, it is difficult to open hydraulic knit bearing, most are not dismantle if still did not find the problem, need to be further apart analysis radiator cooling fan of the PCB, as long as you remove the bearing stator can pull apart seen more understanding, a cooling fan is big, at the bottom, a slightly smaller, in the middle, of the cooling fan is for the inside of the frequency converter cooling accessories and some of the high power IGBT component, small cooling fan are generally for power panel above the heat dissipation of components.
If the cooling fan is broken under the condition of the ambient temperature is not high is can work, whereas high environment temperature converter does not work doesn't rule out small cooling fan is broken.
If it is a big cooling fan is broken, stopped work to run for a while, this time of the IGBT high temperature cause the machine to protect, general heat dissipation problems will arise out of the door does not work.
Why the cooling fan will be bad?
Or the cooling fan is not in conformity with the design, procurement to the gray the cooling fan, fly ash with the heat dissipation fan blade causes more air volume smaller, that we how to handle, suggest inverter manufacturers to use conscience radiator cooling fan manufacturer production of the cooling fan, users need to inverter to clean up.
Wenling city chi automotive air conditioning technology co. , LTD was founded in 2002 in wen ling, is a focus on research and development, production, sales, radiator cooling fan of high-tech enterprises.
Produced dc cooling fans, ac cooling fan, blower, waterproof/dustproof cooling fan, EC conversion and the cooling fan, radiator dc cooling fan, car radiator cooling fan, mute radiator cooling fan, radiator cooling fan, turbo cooling fan, dc dc cooling fan, centrifugal fan, blower, air blower factory, new energy dc cooling fan, brushless motor, etc. , has been widely used in: communications equipment, UPS power supply, medical equipment, electric welding machine, industrial control equipment, household electrical appliances, air purification industry, automobile industry, projectors, beauty equipment, sports equipment, and other areas of the industry.
