Description

Technical Field

[0001] This utility model belongs to the field of cooling fan technology, and in particular relates to a series-connected, replaceable cooling fan. Background Technology

[0002] Computer case cooling fans are key components for ensuring stable computer operation. Their working principle is based on forced convection, using rotating fan blades to push air and form a directional airflow "channel," thereby continuously exchanging and expelling the heat generated by components such as the CPU and graphics card inside the case with external cool air. Their core function is not only to assist in the cooling of core components to improve their performance and lifespan, but also to effectively reduce the internal temperature of the entire system and prevent air stagnation. During assembly, the principle of "front in, back out, bottom in, top out" should be followed. That is, fans should be installed on the front panel and bottom as air intakes to draw in cool air, and fans should be installed on the rear panel and top as exhaust vents to expel hot air. They should be fixed with screws, rubber anti-vibration nails, or quick-release design of the case, and then connected to the motherboard's 4-pin PWM or 3-pin interface to achieve power supply and intelligent speed control. Currently, this mature assembly method has several significant advantages: it achieves excellent heat dissipation performance by constructing an efficient airflow channel; by creating a "positive pressure" environment (intake volume greater than exhaust volume), it can effectively prevent dust from entering through gaps, facilitating maintenance; its modular design gives users great configuration flexibility; at the same time, combined with PWM intelligent speed control technology, it can achieve a perfect balance between quiet operation and efficient heat dissipation, and satisfy users' pursuit of RGB aesthetics and personalization, becoming an indispensable part of modern high-performance computers. In contrast, using existing cooling fans, which involves arranging multiple cooling fans into a combination to increase the effective area, presents the technical problem of inconvenience in replacing multiple cooling fan combinations.
