摘要
The disclosure provides a cage assembly including a cage body and a baffle. The cage body includes a rear portion, a first plate portion, a second plate portion, and a third plate portion. The first plate portion, the second plate portion and the third plate portion are respectively connected to different sides of the rear portion. The third plate portion is located between and connected to the first plate portion and the second plate portion. The rear portion, the first plate portion, the second plate portion and the third plate portion together form an accommodation space therebetween for accommodating a riser card and an expansion card. The first plate portion includes a vent hole connected to the accommodation space. The baffle is configured to be pivoted with respect to the cage body so as to adjust an area of orthogonal projection of the baffle projected on the vent hole.
說明書
This non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No(s). 201910837685.8 filed in China on Sep. 5, 2019 the entire contents of which are hereby incorporated by reference.
The disclosure relates to a cage, more particularly to a cage assembly with a baffle.
In order to make an electronic device (e.g., a desktop computer, a laptop computer or a server) meet the requirement of usage, connecting one or more expansion cards to the mother board of the electronic device is a common way to increase the performance of the electronic device. The connection between the expansion card and the mother board is relied on a riser card.
In general, the riser card and the expansion card are fixed on a cage, and the baffle has a baffle for guiding airflow produced by a dissipation fan of the electronic device to flow towards the expansion card, such that heat generated by the expansion card can be taken away by the airflow.
