Abstract:
1. A cooling element for eliminating electromagnetic noise, formed by bending a plate into a symmetric structure symmetrically comprising: a contact part formed by two ends of the plate extending upwardly and then horizontally extending to confront each other symmetrically, wherein said contact part in connection with an electronic component to absorb heat and noise radiated from said electronic component; a first extension part formed by extending two free ends of said contact part upwardly; a first offset part formed by extending two free ends of said first extension part horizontally extending depart from each, then upwardly, and then horizontally extending to confront each other symmetrically; a second extension part formed by extending two free ends of said first offset part upwardly; a second offset part formed by extending two free ends of said second extension part horizontally extending depart from each, then upwardly, and then horizontally extending to confront each other symmetrically; a third extension part formed by extending two free ends of said second offset part upwardly; and a dissipation part connected with the free ends of said third extension part; wherein the noises absorbed by the cooling element are transmitted along the contact part, said first extension part, said first offset part, said second extension part, said second offset part, said third extension part, and the dissipation part, and mutually offset from each other in accordance with an electromagnetic differential theory and the symmetric structure thereof.
