Abstract: The present invention is related to an extendible and flexible heat-dissipation air conduit base as computer heat dissipation device. The invention mainly comprises an air conduit and fixtures. The air conduit is hollow and flexible with fixtures at both ends. Each fixture is in rectangle shape and connects with the air conduit through a circular hole. The fixture also has several positioning holes and through holes for metal wire to pass through and secure the air conduit with the fixture. By this design, the fixture at one end of the air conduit connects to a heat dissipation fan for CPU. Thus, it provides an excellent heat dissipation channel for computer CPU and helps to achieve the desirable heat dissipation effect.
