Abstract: A hard disk drive heat dissipation device that dissipates heat generated during the operation of a hard disk drive. The device of the present invention is comprised of a body having a surface area of appropriate dimension. A fan is installed onto the body and a number of heat dissipation holes are formed near the outer edges of the body. When the body is mounted onto a hard disk drive, since the body is flush against the surface of the hard disk drive, the body can be tightly secured to the hard disk drive. As such, when the fan is in a state of rotation, the air flow from the exterior is immediately directed onto the hard disk drive such that the heat generated by the hard disk drive does not accumulate on the hard disk drive surface, but is exhausted out through the heat dissipation holes in the body to thereby enable the rapid cooling of the hard disk drive.

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.

Abstract: A CPU heat dissipating apparatus including a radiating panel attached to the top side of a CPU to hold a fan between two opposite upright side walls on the radiating panel, and a mounting frame fastened to the CPU to hold down the heat sink, wherein the mounting frame has two short downward hooks respectively hooked on two opposite mounting grooves on two opposite upright side walls of the radiating panel, two long downward hooks hooked on the border of the CPU to tightly secure the radiating panel to the CPU, and two oblique finger plates for moving by fingers to deform the mounting frame for permitting the long downward hooks to be hooked on or released from the CPU.
