Each fastener includes a screwing pole, a first elastic member and a second elastic member encircling the screwing pole, and a fastening cylinder engaging with the screwing pole. Each screwing pole includes a head, a shaft extending coaxially downwardly from the head, and a post extending coaxially downwardly from the shaft. For each fastener, the screwing pole extends through a corresponding fixing cylinder of the fan, the first elastic member is compressed between the head and the corresponding fixing cylinder, the second elastic member is compressed between the corresponding fixing cylinder and the fastening cylinder, and the post protrudes from the fastening cylinder and is engaged with the supporting board."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Heat dissipation device with two spring fastners","description":"An exemplary heat dissipation device includes a fan having fixing cylinders, a heat sink having a supporting board, and fasteners fixing the fan to the heat sink.
