Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation fans, in particular to a heat dissipation fan which is easy to assemble and disassemble. Background Art

[0002] The blades of axial flow cooling fans push the air to flow in the same direction as the axis. The impeller of an axial flow fan is somewhat similar to a propeller. When it is working, most of the airflow flows parallel to the axis, in other words, along the axis direction. When the inlet airflow of the axial flow fan is free air with zero static pressure, its power consumption is the lowest. When it is running, the power consumption will increase with the increase of the airflow back pressure. Axial flow fans are usually installed on the cabinets of electrical equipment and are sometimes integrated on motors. Due to their compact structure, axial flow fans can save a lot of space and are easy to install, so they are widely used.
