DC [DC fan] Why are mostly square fans, can they be made into rectangles?

The DC DC fans we see, such as computer CPU cooling fans, chassis fans, refrigerator cooling fans, inverter cooling fans, switch cooling fans, etc., are mostly square-shaped DC fans used in electronics, electrical appliances, and industrial equipment. The small part is round or frameless, can it be made into a long strip? For our commonly used axial fans, the direction of rotation of the fan blades is 90 degrees with the wind direction. Because the length of each fan blade is the same, when turned, a few leaves form a circle. Of course, the outer frame can only be Square or round, if you must make it into a rectangle, you can only extend the outer frame to both sides, but the fan blades remain the same, and the heat dissipation effect is the same as the original square DC fan. Of course, if the customer must have a rectangular shape and a partial heat dissipation method, it is also possible. For example, we have a large fan on the door of a shopping mall, which is about the same length as the door, but very narrow. This is a cross-flow fan with long blades. Cylindrical, the direction of fan blade rotation is the direction of wind. Welcome to the heat dissipation classroom and news center of the cooling fan manufacturer again.
