Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and specifically to a novel heat dissipation structure that optimizes airflow by combining a fan and a radiator. Background Technology

[0002] As the performance of electronic devices continues to improve, the power consumption and heat generation of their internal hardware are also increasing. Especially in fields such as computers, servers, smartphones, automotive electronics, and industrial equipment, electronic components generate a significant amount of heat during operation. If this heat cannot be dissipated effectively and promptly, it can lead to decreased device performance, hardware damage, and even safety hazards. Therefore, heat dissipation has become a crucial aspect of ensuring the stable operation of electronic devices, and the main function of a radiator fan is to accelerate heat dissipation through forced convection. Typically, radiator fans are used in conjunction with metal heat sinks. The heat sinks absorb heat from the heat source, while the fan generates airflow through rotation, helping to remove the accumulated heat and expel it from the device.

[0003] The efficiency of a cooling fan depends on factors such as its rotational speed, size, blade design, and airflow. High-efficiency cooling fans can achieve rapid heat transfer and reduce noise through large airflow and precise blade design. For example, Chinese utility model patent CN202391779U discloses a quick-disassembly fan structure. In this patent, a fan bracket 1 and a fan frame 2 connected to the fan bracket 1 are included. A heat sink 3 is mounted on the other side of the fan bracket 1. Multiple snap-fit ​​flanges 202 are spaced apart on the outer circumference of the fan frame 2, and snap-fit ​​seats 101 that match the snap-fit ​​flanges 202 are provided at corresponding locations on the fan bracket 1. As disclosed in this patent, most cooling fans on the market currently use a similar structure to the fan frame 2 for support.
