Integrated heat sink unit and heat dissipation device with curved surface structure

Abstract

This invention discloses an integrated heat dissipation fin unit and heat dissipation device with a curved surface structure. The integrated heat dissipation fin unit is used to disrupt the laminar boundary layer to form local turbulence. It includes an air inlet, an air outlet, and a curved guide section. The air inlet is used to receive unheated airflow. The air outlet is arranged opposite to the air inlet and is used to output the heat-exchanged airflow. The two ends of the curved guide section are connected to the air inlet and the air outlet, respectively. The curved guide section extends in a continuous wave shape along the flow direction of the airflow. The unheated airflow enters from the air inlet in a first direction, is guided by the curved guide section, and flows out from the air outlet in a second direction. The bending direction of the curved guide section is perpendicular to the first direction. The airflow is guided by the curved guide section to flow through the integrated heat dissipation fin unit along a curved path to disrupt the laminar boundary layer and form local turbulence.
