Heat dissipating mechanism adapted to an electronic device and electronic device therewith

摘要

A heat dissipating mechanism includes a first housing, a second housing and a tributary hole structure. The first housing is installed on a host casing. At least one inlet and at least one outlet are formed on two sides of the first housing. The second housing combines with the first housing, and the second housing and the host casing form a flow channel for communicating with the at least one inlet and the at least one outlet, so as to guide liquid from the at least one inlet to the at least one outlet. The tributary hole structure is formed on the flow channel and located in a position between the at least one inlet and the at least one outlet. The tributary hole structure is higher than the at least one outlet for guiding air from the at least one inlet to a fan.

1. A heat dissipating mechanism adapted to an electronic device, the electronic device comprising a host casing with a heat dissipating hole formed thereon and a fan containing chamber formed therein, the heat dissipating hole communicating with the fan containing chamber, and a fan installed inside the fan containing chamber of the host casing, the heat dissipating mechanism comprising:
a first housing installed on the host casing, at least one inlet and at least one outlet being formed on two sides of the first housing, the at least one inlet being higher than the at least one outlet, the at least one outlet being oriented on a side whereon the heat dissipating hole is formed; a second housing combined with the first housing and located between the first housing and the host casing, the second housing and the host casing forming a flow channel for communicating with the at least one inlet and the at least one outlet so as to guide liquid from the at least one inlet to the at least one outlet, the second housing and the first housing cooperatively encircling a hollow chamber, and the hollow chamber being spaced from the fan containing chamber by the flow channel; a tributary hole structure formed on the second housing and located between the at least one inlet and the at least one outlet, the tributary hole structure being higher than the at least one outlet and communicating with the hollow chamber; a partition wall formed inside the host casing, the partition wall being located below the second housing and extended into interior of the host casing for separating the at least one outlet and the heat dissipating hole, wherein air drawn by the fan is separated from the liquid discharged via the flow channel and is guided to the heat dissipating hole via the tributary hole structure; and at least one communicating tube disposed through the flow channel, two ends of the at least one communicating tube respectively connected to the second housing and the partition wall for communicating with the hollow chamber and the fan containing chamber.
