DETAILED DESCRIPTION
[0020] The present invention provides a high-reliability heat sink chip pad. Figure 1-2 As shown, it includes a pad base 11, a pad cavity 12, a first support block 13, a heat dissipation chip 14, a heat dissipation hole 15, a second support block 16, an elastic clip 17, a sliding baffle 18, a first slot 20, an elastic part 21, a clamping block 22, a limit slot 23, a limit block 24, and a second slot 25.
[0021] like Figure 1-2 As shown, a pad cavity 12 is provided in the pad base 11, and a first support block 13 is fixedly connected in the pad cavity 12. First slots 20 are provided on both side walls of the pad base 11 and both sides of the first support block 13. A clamping assembly is provided in the first slot 20. Second support blocks 16 are fixedly connected on both sides of the first support block 13. An elastic clip 17 is clamped between the second support block 16 and the clamping assembly. The heat dissipation chip 14 is placed on the two elastic clips 17 on both sides of the first support block 13. The elastic clips 17 are made of elastic metal material.
[0022] A plurality of heat dissipation holes 15 are formed on the heat dissipation chip 14 . The heat dissipation holes 15 extend along the extension direction of the first support block 13 , and the heat dissipation holes 15 are arranged at equal distances from each other.
[0023] Limit blocks 24 are also provided on both side walls of the pad base 11 and both sides of the first support block 13. A sliding baffle 18 is slidably connected inside the limit block 24. A second slot 25 is fixedly provided at both ends of the sliding baffle 18. The second slot 25 is slidably connected to the limit block 24, and the width of the second slot 25 is equal to the width of the limit block 24.
[0024] The clamping assembly includes two elastic members 21 and a clamping block 22. One end of the elastic member 21 is fixedly connected to the clamping block 22, and the other end of the elastic member 21 is fixedly connected to a side wall of the first slot 20. The clamping block 22 is slidably connected to the first slot 20. A limiting groove 23 is provided on an end surface of the clamping block 22 away from the elastic member 21, and the limiting groove 23 is adapted to the elastic clip 17.
[0025] When the chip is assembled according to this scheme, first, the elastic clip 17 is clamped between the second support block 16 and the clamping block 22 respectively. When the elastic clip 17 is clamped between the second support block 16 and the clamping block 22, the elastic clip 17 pushes the clamping block 22 toward the first slot 20 through the limit groove 23. The first slot 20 compresses the elastic part 21, and the elastic part 21 generates a reaction force on the elastic clip 17 through the clamping block 22.
[0026] Then, the heat dissipation chip 14 is pressed onto the elastic clip 17, the limit block 24 is aligned with the second slot 25, and the limit block 24 is pushed into the second slot 25. Finally, the sliding baffle 18 slides relative to the second slot 25, and the elastic clip 17 generates a reaction force on the first slot 20.
[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
