Description

Technical Field

Background Art

[0002] The electronic components in electronic products are gradually becoming more functionally centralized and powerful. For example, the display adapter device is designed to meet the needs of higher-level graphics functions, e-sports games, AI functions, etc., which will generate more heat when the display adapter device (or other electronic components) is in operation. If this heat cannot be removed in time, it will lead to problems with the stability of the performance and shortened life of the electronic products. Therefore, in order to maintain the operating temperature of such electronic components within an appropriate range, effective heat dissipation technology is critical. Therefore, using heat dissipation devices to effectively dissipate heat from electronic components and electronic components has become a normal focus of the industry.

[0003] A turbofan / centrifugal fan is often used in the field of personal computer heat dissipation. Since the gas flow direction of the turbofan is perpendicular to the rotating shaft, the turbofan / centrifugal fan can output a larger air volume within a certain space, improving the heat dissipation effect. It is often used in high-performance display adapter heat sinks. However, this type of centrifugal fan is often complicated in structure and large in size, which will occupy a large space inside the computer, making it difficult to miniaturize the entire computer. It is necessary to improve and make breakthroughs.

[0004] Therefore, the creator of this case has learned about the shortcomings of centrifugal fan heat dissipation technology and the fact that its structural design is not ideal, and has begun to develop a solution, hoping to develop an axial air intake and radial pressurized air outlet blast fan heat dissipation structure with better airflow pressurization efficiency and space utilization effect, so as to serve the general public and promote the development of this industry. After a long period of thinking, the present utility model was created. Utility Model Content

[0012] In this embodiment, when the hub and the impeller rotate, the air around the heat sink fin group enters the flow space, and the heat source on the heat sink forms hot air along with the incoming air, and enters the blast fan axially from the inlet.
