The disclosure provides a centrifugal fan structure. The centrifugal fan structure includes a top case, a body, a fan, and a muffler pipe. The top case includes an air inlet. The body includes a sidewall, a tongue part, and a bottom case. The sidewall and the tongue part are disposed on the bottom case. The sidewall includes an opening. The fan is disposed in the body, and includes a shaft and a plurality of fan blades connected to the shaft. The muffler pipe is disposed on the sidewall, and the opening of the muffler pipe is corresponding to the opening of the sidewall. The length of the muffler pipe is proportional to the wavelength of the blade passing frequency of the fan.

An electronic device includes a housing, at least one cover, and a hard disk. The housing having an accommodating space, an inner surface, an outer surface, and at least one through hole communicating with the inner surface and the outer surface. The cover located at an outer side of the housing in which a chamber is formed between at least one portion of the cover and at least one portion of the outer surface, and the chamber is communicating with the accommodating space through the through hole. The hard disk disposed in the accommodating space.

Electronic device

Heat dissipation component includes a fan unit, a first housing, and an airflow-guiding plate. The fan unit includes a fan blade portion, and a fan housing including a first air-guided cap and a second air-guided cap. The second air-guided cap, having a fan inlet, is disposed on the first air-guided cap. The fan blade portion is disposed between the first air-guided cap and the second air-guided cap, and pivotally-connected to the fan housing at the second air-guided cap. The first housing is disposed on a side of the second air-guided cap away from the first air-guided cap. An inlet airway is formed between the first housing and the fan unit. The airflow-guiding plate is disposed between the first housing and the second air-guided cap, and extended from outline of the main fan inlet toward outline of the inlet airway and away from the main fan inlet.
