Abstract:
1. A water cooled heat dissipation module for an electronic device comprising: a base disk having a containing space with a plurality of cooling strips providing at the bottom thereof; a water suction disk being disposed on top of said base disk, providing a water chamber and having an inlet and an outlet next to the periphery thereof, accommodating said cooling strips, having a suction space with a water passage therein to communicate with said inlet; a water guide being a circular wall and integrally joined to the top of said suction disk eccentrically; a cover further comprising an intake pipe connector for communicating with said inlet, a discharge pipe connector for communicating with said outlet, a bulge part corresponding to said water guide and a cylindrical receiving shell extending upward from said bulge part; and a guide fan further comprising a cylindrical body part, a plurality of blades and a spindle for being received in said receiving shell and said bulge part; wherein, a spindle seat is disposed at said water suction disk and concentric with said water guide for joining with an end of said spindle; said spindle passes through said guide fan axially with another end of said spindle joined to a motor disposed next said cover; said water guide has a small circular wall section jutting toward the periphery of said water suction disk; a guide port is disposed at the water suction disk next to said small circular wall section; said spindle seat, said receiving shell and said spindle have a common axis; said bulge part with said receiving shell has the same shape as said guide fan for containing said guide fan; said suction disk has a water hole to communicate with said water passage such that a fluid flow enters said water suction disk via said intake pipe connector and said inlet, moves along said water passage to said blades via said water hole, enters said containing space via said guide port, and flows outward via said outlet and discharge pipe connector.
