Claim:
1. A heat dissipation structure, comprising: a heat-dissipation spacer defining a first surface and a second surface opposite to said first surface; a first heat dissipation layer comprising a plurality of first heat pipes, each said first heat pipe comprising a first segment, a second segment and a third segment, the second segment of each said first heat pipe being connected between the first segment and third segment of the respective said first heat pipe, the first segment of each said first heat pipe being positioned in said first surface of said heat-dissipation spacer, the first segments of said first heat pipes being disposed in parallel; a second heat dissipation layer comprising a plurality of second heat pipes, each said second heat pipe comprising a first segment, a second segment and a third segment, the second segment of each said second heat pipe being connected between the first segment and third segment of the respective said second heat pipe, the first segments of said second heat pipe being positioned in said second surface of said heat-dissipation spacer, the first segments of said second heat pipes being disposed in parallel; and a radiation fin set comprising a plurality of radiation fins, each said radiation fin comprising a peripheral edge, the peripheral edges of said radiation fins being arranged together to provide a contact surface for enabling said second surface of said heat-dissipation spacer to be placed on said contact surface in such a manner that said first segment of each said second heat pipe of said second heat dissipation layer is set in between said heat-dissipation spacer and said radiation fin set and kept in contact with said heat-dissipation spacer and said radiation fin set; the third segment of each said first heat pipe of said first heat dissipation layer and the third segment of each said second heat pipe of said second heat dissipation layer are respectively inserted through said radiation fin set; wherein: at least a party of the first segment of at least one said first heat pipe of said first heat dissipation layer is disposed overlapped on at least a part of the first segment of at least one said second heat pipe of second heat dissipation layer in a parallel manner.
