Centrifugal fans are sometimes called radial fans or centrifugal blower fans. They have a motor-driven hub which contains an impeller that discharges air into the housing and then directed to an outlet. The centrifugal fan exhausts air at an angle of 90 degrees (perpendicular to the air inlet). Centrifugal type fans mainly pressurize the air in the blower housing. Compared with axial fans, they pr...

As laptops become more powerful and compact, cooling systems are playing an increasingly critical role. Why do laptops use blowers instead of axial fans?They directly impact CPU and GPU performance, system stability, and user comfort. Why Does Cooling Matter? Though small in size, processors (CPU) and graphics chips (GPU) generate a tremendous amount of heat. Without proper cooling, laptops may ov...

In the design of underground garage ventilation systems, two common approaches are natural ventilation and mechanical ventilation. Although natural ventilation is often the most cost-effective method, it greatly impacts the overall building layout and outdoor landscaping. For instance, if a residential complex with a basement area of about 40,000 square meters adopts natural smoke exhaust and natu...
