Patent number: 12200896Abstract: An air-cooled carrier of heat-generating electronic components includes a frame, a plate, and baffles. The plate coupled to the frame divides airflow in the frame into two channels. Opposite sides of each channel along a first direction carry inlet and outlet. A pair of baffles is coupled to each channel, each baffle comprises a mounting part, an arc-shaped elastic part, and a blocking part. The mounting part is fixed to the frame and the arc-shaped elastic part. The blocking part is fixed to the arc-shaped elastic part and extends to middle of the airflow cavity in a second direction perpendicular to the first direction. In the absence of a mounted storage component, the elastic part bringing the blocking part to a first position and so blocking air flow from that outlet to that inlet.Type: GrantFiled: May 9, 2022Date of Patent: January 14, 2025Assignee: Fulian Precision Electronics (Tianjin) Co., LTD.Inventors: Pao-Ching Wang, Ke-Cheng Lin
