Fixing means for heat dissipater
View Patent ↗A fixing means for a heat dissipater is provided to position the heat dissipater and a heat-generating element, which includes a heat-dissipating base and a positioning frame. The surface of the heat-dissipating base is provided with a plurality of heat-dissipating pieces. The center of the plurality of heat-dissipating pieces is provided with a sliding groove. Further, the positioning frame is formed into a T-lettered shape and constituted of a transverse rod and a pressing end. The pressing end is accommodated in the sliding groove of the base to abut against the surface of the base. Both side faces of the transverse rod are provided with a screw hole, respectively, for receiving a locking element. With the downward force generated by the connection of the locking element, the pressing end of the positioning frame can be caused to abut against the surface of the base, thereby to efficiently press the gravity center of the base and fix the position of the heat dissipater with respect to the heat-generating element.
1. A fixing means for a heat dissipater, capable of fixing the heat dissipater provided on a substrate, comprising:
a base having a surface with a plurality of heat-dissipating pieces thereon, a center of the heat-dissipating piece having a sliding groove perpendicular to an orientation of the heat-dissipating pieces;
a pair of connecting ends formed on the substrate; and
a positioning frame having at least one transverse rod connected vertically with a pressing end, the pressing end being accommodated in the sliding groove to abut against the surface of the base, the transverse rod being located over the heat-dissipating pieces, to have both ends extended out of the heat-dissipating pieces to connect with the pair of connecting ends, respectively;
wherein the positioning frame is connected to the connecting ends to generate a downward force, thereby to cause the pressing end to downwardly press the surface to fix the position of the base.
2. The fixing means for a heat dissipater according to claim 1 , wherein each end of the transverse rod is provided with a screw hole and a locking element is used to secure the transverse rod with the connecting end through the screw hole.
3. The fixing means for a heat dissipater as claimed in claim 1 , wherein the screw hole is an elongated hole such that the locking element is capable of sliding in the elongated hole.
4. A fixing means for a heat dissipater, the heat dissipater comprising a base having a surface with a plurality of heat-dissipating pieces thereon, a center of the heat-dissipating piece having a sliding groove, the fixing means comprising:
a first transverse rod, a second transverse rod and a pressing end, each of the first transverse rod and the second transverse rod defining a through hole therein, the pressing end passing through the through hole in each of the first transverse rod and the second transverse rod, the first transverse rod and the second transverse rod being capable of rotating around the pressing end, each of the first transverse rod and the second transverse rod defining two screw holes respectively in two ends thereof.
5. The fixing means for a heat dissipater as claimed in claim 4 , further comprising four locking elements, the screw holes are elongated holes such that the locking elements are capable of sliding in the elongated holes.
6. A heat dissipater structure, comprising:
a base having a surface with a plurality of heat-dissipating pieces thereon, a center of the heat-dissipating piece having a sliding groove; and
a fixing means for fixing the base on a substrate, the fixing means comprising:
a first transverse rod, a second transverse rod and a pressing end, each of the first transverse rod and the second transverse rod defining a through hole therein, the pressing end passing through the through hole in each of the first transverse rod and the second transverse rod, the first transverse rod and the second transverse rod being capable of rotating around the pressing end, each of the first transverse rod and the second transverse rod defining two screw holes in two ends thereof.
7. The heat dissipater as claimed in claim 6 , further comprising four locking elements, the screw holes are elongated holes such that the locking elements are capable of sliding in the elongated holes.
