Description

Technical Field

[0001] This application relates to the technical field of a heat dissipation device, and more particularly to a heat dissipation device and its integrated axial fan. Background Technology

[0002] In existing technologies, water-cooled radiators (water cooling radiators) are usually paired with fans to improve heat dissipation efficiency. Furthermore, to secure the fan, fan ribs are typically installed on the fan frame or mounting surface. While these ribs provide necessary support, they may obstruct the fan's exhaust path, leading to restricted or turbulent airflow, further reducing fan efficiency.

[0003] Specifically, when a fan is running, airflow passes over the blades and enters the cooling fins of the radiator for heat exchange and to remove heat. However, if the fan fins are improperly positioned, they may partially obstruct the fan's exhaust vents, interfering with airflow and affecting wind speed and direction. This airflow obstruction can reduce fan efficiency, thus impacting the radiator's cooling performance. Furthermore, obstructed airflow can increase fan noise or cause localized pressure loss, requiring the fan to consume more power to maintain normal operation, and even negatively impacting the overall stability of the cooling system. In addition, the arrangement of power cables can also affect the aforementioned airflow direction.

[0004] Therefore, the goal of this applicant's research is to improve the design of the fan and wiring configuration to reduce the impact of airflow and improve heat dissipation efficiency. Utility Model Content

Each fan unit includes a stator and an impeller connected to and rotating relative to the stator. Each stator is mounted on a mounting base.
