Abstract:
1. An electronic device, comprising: a casing including an interior space; a heat generation source; an airflow guiding structure being in contact with the heat generation source and including one air inlet; and a jet flow generator which is disposed within the interior space of the casing together with the heat generation source and the airflow guiding structure, and has a first nozzle facing the air inlet at a distance apart, the jet generator being configured to emit a first air jet flow traveling at a velocity greater than 0.1 meters/second (m/s) and, due to a fluid pressure difference between the first air jet flow and neighboring air near first air jet flow, the neighboring air being pulled into the airflow guiding structure along the air inlet; wherein the airflow guiding structure comprises a plurality of cooling fins, which stretch from the air inlet toward a direction away from the first nozzle, and an edge surface, located at the air inlet and facing the first nozzle of the jet flow generator, the first nozzle of the jet flow generator includes one first side and one second side in an opposite direction, and a periphery of the edge surface extends from the first side to the second side.
