BACKFLOW PREVENTION DEVICE, ELECTRONIC APPARATUS, AND METHOD FOR PRODUCING BACKFLOW PREVENTION DEVICE
摘要
<p>A backflow prevention device (20) is disposed between a heat-generating component (1c) that generates heat and an air supply unit (6) for supplying air to the heat-generating component (1c). The backflow prevention device (20) includes a plurality of flaps (30) to be opened by airflow supplied from the air supply unit (6) and to be closed by gravity when the airflow stops; a frame case (21) that rotatably supports the plurality of flaps (30); and a connecting member (40) that connects between the plurality of flaps (30).</p>
