Abstract
A vibration and shock resistant heat dissipating device for removing heat from a heat generating object is disclosed. The heat dissipating device includes a retaining clip having a central member and a pair of legs depending downwardly therefrom. An aperture is disposed through the central member and defines a central member bore having female threading formed therein. The free ends of the pair of legs are secured relative to the heat generating object. A heat dissipating member having a threaded base portion with a substantially flat bottom surface is adapted to be threadably received in the center member bore so that the flat bottom surface of the heat dissipating member is in flush thermal communication with the heat generating member. A ratchet member is disposed between the retaining clip and the heat dissipating member for controlling threaded receipt of the threaded base portion in the retaining clip. The ratchet member permits only inward installation threading of the base portion into the center member bore while preventing threaded removal of the base portion out from retaining clip. Use of a tool enables threaded removal of the base portion out from the retaining clip.
