The frameless cooling fan of Wellsunfan is a widely used component in the field of electronic device cooling. Its main feature is the absence of a traditional fan frame. It eliminates the external frame design of conventional fans, retaining only core components such as the blades and motor. This design reduces air flow resistance during operation, increases air flow speed, and thereby enhances cooling performance. Additionally, the frameless design makes the fan appearance more streamlined, facilitating easier integration with various devices.
Common cooling fans are typically framed and square-shaped. There are also special types such as frameless fans with triangular brackets, straight-line brackets, etc. So, which type of cooling fan produces a larger air volume?
Air volume of a cooling fan, simply put, refers to the volume of air moved by the fan while it's operating. Air volume data is measured using a wind tunnel machine. The testing method involves directing the air blown by the cooling fan into the wind tunnel machine. Inside the wind tunnel machine, a sensor transmits the data to a database, which then computes the air volume. The volume of air mainly depends on the shape of the blades and secondly, the shape of the frame.
Therefore, when comparing the air volume of square-shaped cooling fans and frameless cooling fans, the first thing to look at is which fan blade moves a larger volume of air. Secondly, it's about the frame's ability to collect and intake air. However, since the air blown by frameless cooling fans is dispersed, it's impossible to direct all the air into the wind tunnel for measurement. As a result, it's not possible to compare the air volume of these two types of fans on an individual basis unless the frameless cooling fan is combined with a heatsink to direct the air from one point for measuring the combined air volume.
Frameless cooling fans can be categorized into various types based on different application scenarios and demands, such as axial and centrifugal types. Axial fans mainly create axial airflow through the rotation of the blades, suitable for situations requiring linear airflow. Centrifugal fans draw air from the center and expel it radially, suitable for situations requiring a change in airflow direction. Additionally, the number and shape of the fan blades, motor types, etc., are designed and adjusted based on specific needs.
With the continuous development of electronic devices and increasing cooling demands, frameless cooling fans, as an efficient and streamlined cooling solution, have a broader application prospect. In the future, frameless cooling fans are expected to achieve further innovation and development in materials, structures, intelligent control, etc., to meet more diverse cooling needs.
