Embodiment

For making the duty juror can further understand content of the present utility model, please cooperate referring to brief description of drawingsfig, describe in detail as the back:

Please referring to shown in Fig. 1,3, the utility model is all sides of the specific senior computing wafer 20 on circuit board 10 (for example: the shows wafer of display card or the central processor CPU of motherboard) mainly, are provided with two groups of relative jacks 11,12 at least.

One metal cover body 30 is five involutions and downward opening structure, and the perimeter side walls of this metal cover body 30 is slightly outwards to be the expansion shape, and this angle that expands outwardly, and is for good with outwards about 30 degree of vertical line; This metal cover body 30 is outward extended with the protruding wing 31 of button hole 32 again to the two relative edges bottom that is less than perimeter side walls.

Please referring to shown in Fig. 1～3, this metal cover body 30 is covered with entire wafer 20 bodies, then touch mutually with wafer 20 end faces the below, top of metal cover body 30, be to be provided with one deck heat-conducting cream 60 at metal cover body 30 with wafer 20 contact-making surfaces simultaneously, the heat that wafer 20 is produced evenly reaches on the metal cover body 30, above this metal cover body 30, then can add devices such as fin 40 and fan 70 again in order to heat radiation, and fixing by 10 of fin 40 and circuit boards, simultaneously metal cover body 30 crampings are fixed; Wherein, between this metal cover body 30 and fin 40, also be provided with one deck heat-conducting cream 61.

A kind of embodiment of the fixed form that above-mentioned fin 40 and circuit board are 10, it is the stator 41 that is provided with protrusion in the two opposite sides of fin 40, has button hole, and run through this stator 41 and the jack 12 of clasp nail on circuit board 10 is fixing with two nail catchers 50, can be simultaneously with metal cover body 30 simultaneously cramping fix; And the top of fin 40 also can be organized and establishes fan 70, to increase radiating effect.

Please referring to shown in Fig. 1,2,4, metal cover body 30 itself is also detained voluntarily to be fixed on the circuit board 10, be it to be had the protruding wing 31 of button hole 32 is involutory to be run through with two nail catchers 51 in another jack 11 of circuit board 10 again, and metal cover body 30 directly followed closely solid on circuit board 10; When metal cover body 30 and fin 40 distinctly all were fixed on the circuit board 10, shown in Fig. 2,5, the protruding wing 31 of its this metal cover body 30 was the relative shape that staggers with the stator 41 of fin 40, made button solid more easy.

Because design of the present utility model has clever thought, has all following advantage on the implementation:

1, the utility model is covered with a metal cover body above wafer; and the metal cover body is touched mutually with the wafer top, and can protect wafer not to be subjected to extraneous scratch or damage on the one hand, reduce the damage on using; and can prolong useful life of wafer, be major advantage of the present utility model.

2, the perimeter side walls of the metal cover body of metal cover body is slightly outwards to be the expansion shape, has more stability when making it cover in wafer, and the easier wafer that fits in top, is another advantage of the present utility model.

3, the metal cover body is to be provided with heat-conducting cream at the contact-making surface with wafer, fin, makes the heat on the wafer be able on average and rapidly shed, and the fin of being established by upper set easily absorbs, and is another advantage of the present utility model.

Because one of this creator constantly asks progressive positive attitude; this product of new discovery at first; have as above-mentioned protection wafer not by the advantage of scratch, damage; reduce the artificial damage on using; prolong the useful life of wafer; value with industry should meet the important document of applying for utility model patent, and the spy files an application.
