ABSTRACT:
A convection type heat dissipation device for computers that is adjustable with respect to a heat source including a frame disposed inside the computer mainframe, the frame is connected to at least one movable tube fittingly provided on a guide duct. In use, it is only necessary to adjust the angle of an orifice portion at one side of the movable tube so that the orifice portion faces the heat source (e.g., the location of the central processing unit) within the computer mainframe. By actuating an air ventilation device located at the orifice portion, the heat generated within the computer mainframe can be quickly dissipated. Besides, the cooler ambient air may be drawn into the computer mainframe. By means of the arrangement of convection of air currents within the computer mainframe, the central processing unit and the other components of the computer may operate in a relatively low temperature and stable environment.
