Abstract: Embodiments of the present invention relate to a heat dissipating device including a chassis, a backplane, at least one rear board, and at least one fan, where the chassis includes horizontal wall panels, vertical wall panels, and a rear wall panel; the chassis includes one or more partition plates; the rear board includes one or more second hole areas; and the one or more partition plates, the horizontal wall panels, the vertical wall panels, the rear wall panel, the backplane, and the rear board form a cooling air duct that does not pass a front board, so that under an effect of the fan, a cooling air flow is discharged out of the chassis after passing the rear board, the second hole area, and the fan, so as to implement heat dissipation for a functional module on the rear board.

Abstract: Embodiments of the present invention disclose a server, and relate to the field of computer communications, so that maintainability of a server is improved, a heat dissipation function of the server is ensured, and heat dissipation reliability of the server is improved through online replacement of a heat dissipation fan and a server mainboard. A server includes: a chassis, a backplane with a ventilation opening, a rear board, a first air ducting apparatus, and at least one fan module, where the backplane is located in the middle of the chassis, and the rear board is connected to a rear side of the backplane in a pluggable manner; the fan module is disposed side by side with the rear board along a horizontal direction, and is connected to the rear side of the backplane in a pluggable manner.
