Patent ID: 10993351

Abstract:
An electronic device and a heat-dissipation device for an electronic device are provided. The heat-dissipation device comprises an airflow channel; an airflow source located in the airflow channel; a plurality of elongated heat-dissipation fins arranged in the airflow channel; and a plurality of heat-dissipation flow-guiding devices arranged in the airflow channel and between the airflow source and the plurality of elongated heat-dissipation fins, wherein the plurality of heat-dissipation flow-guiding devices include a first heat-dissipation flow-guiding device in a central position of the airflow channel and a second heat-dissipation flow-guiding device on two sides of the airflow channel, and a longitudinal distance between the first heat-dissipation flow-guiding device and the airflow source is less than the distance between the second heat-dissipation flow-guiding device and the airflow source.
