Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation fans, and more specifically, particularly relates to a heat dissipation fan module with adjustable wind direction. Background Art

[0002] Computers are currently the most effective office equipment. Whether it is a desktop computer or a laptop computer, the temperature inside the computer rises sharply during the long-term operation of the motherboard, hard disk or CPU. In order to ensure the normal operation of the computer, a cooling fan is installed inside the computer to extract the hot air inside the computer to achieve the effect of heat dissipation and cooling. Existing computers often install multiple sets of fans to achieve the purpose of simultaneous air intake and outlet, but the positive and reverse wind directions of existing fans are mostly fixed and cannot be flexibly adjusted according to different installation positions, resulting in users needing to customize fans with different wind directions or reverse-mounted fans to meet the computer's heat dissipation needs. However, reverse-mounted fans affect the appearance, and customizing fans with different wind directions leads to higher costs. Therefore, in view of this, research and improvement are conducted on the existing structure and deficiencies, and a cooling fan module with adjustable wind direction is provided, in order to achieve a more practical purpose.
