Internal and external connecting liquid cooled heat sink device

Abstract: The present invention provides an internal and external connecting liquid cooled heat sink device, which includes a holding case, a water tank facility, a heat dissipating unit, pipes and a water cooled head. The holding case retains the water tank facility and the heat dissipating unit connected in series using the pipes. The pipes are connected to a water cooled head to enable circulating and dissipating of heat. The holding case can be removable inserted into a retaining slot of a host computer or independently connected to an outer case of the host computer. Moreover, a plurality of through holes are defined in each heat dissipating fin of a liquid cooled exchange device, thereby enabling the heat dissipating unit to effectively achieve increased heat dissipation effectiveness when circulating and dissipating heat.
