The anatomy of the cooling fan working at low temperature and the importance of the air volume tester

Generally, the environment where the heat dissipation fan is used is a high temperature environment, but some special products need to work at room temperature. In low temperature areas, the heat dissipation fan also needs to work. Then, can the heat dissipation fan work at a low temperature such as -20 degrees? For customers with such requirements, we will design a cooling fan that can work at low temperatures for customers. Normally, the cooling fan of ordinary oil-impregnated bearings may not work if it is below -10 degrees. Lubricating grease is possible Solidified. Our design is that using ISC ball bearings imported from Japan, it can still work normally at a low temperature of -20 degrees, but the speed will be lower, and the temperature will be lower, causing the bearing to solidify, freeze, and the shaft core cannot rotate. At this time, A short circuit will be formed inside the cooling fan, the temperature of the motor rises, the temperature rises, the ice around the shaft core melts, and the cooling fan can operate. Most of the cooling fan manufacturers have less than 100 people. Their main job is to buy some materials and do an assembly work. Some small-scale cooling fan manufacturers want to have an air flow tester. Is this important? ? When we develop a new mold, we want to compare the air volume and wind pressure of our competitors, and confirm whether the mold we opened is successful. When we make a cooling fan sample, we must confirm the air volume and whether the air pressure can meet the customer's requirements. All of these need to use air volume, air pressure tester, data, strong convincing, high reliability, small cooling fan factory Without this equipment, including the air volume and air pressure parameters in the specifications, they are all estimated and cannot stand scrutiny. Therefore, the manufacturers of cooling fans want to get an air volume tester.
