Abstract
A fan duct for dissipating heat generated by a central processing unit of a computer is disclosed. The fan duct has a main body defining an air inlet and an air outlet. An electrical fan is mounted to the main body below the air outlet. A knob is attached to a top wall of the main body and located above the fan. An enclosure of the computer includes a back panel and a top cover. The top cover is attached with a hook. The fan duct is firstly assembled to the back panel by extending screws through the back panel to threadedly engage with the fan duct. The top cover is then mounted to the back panel to reach a finally assembled position in which the hook engages with the knob, whereby a portion of a weight of the fan is supported by the hook.
