To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:
Fig. 1 is the display card cooling device STRUCTURE DECOMPOSITION figure of the utility model;
Fig. 2 is the display card cooling device structure assembly drawing of the utility model;
Fig. 3 is the display card cooling device cut-open view of the utility model;
Fig. 4 is the spring clinching structural representation of the utility model;
Fig. 5 is the fan cover part-structure cut-open view of the utility model.
Embodiment
Like Fig. 1, shown in 2 and 3; The display card cooling device of the utility model comprises spring clinching 1, fan cover 2, fan 3 and heat radiator 4; Fan 3 passes through screw retention on heat radiator 4; Fan cover 2 places the blade top of fan 3, and the intermediate portion is divided into a suitable open circles of maximum gauge when rotating with fan 3, and fan cover 2 is fixedly connected through spring clinching 1 with heat radiator 4.When fan and fan cover were one-body molded, fan then need not be fixedly connected with heat radiator, directly connected fan cover through the spring clinching and heat radiator gets final product.
As shown in Figure 4; Spring clinching 1 comprises head 11, middle part 12, pothook 13 and is set in the compression spring 10 on the middle part 12; The diameter of head 11 is greater than the external diameter (the spring external diameter is meant the maximum outside diameter of spring) of compression spring 10; Pothook 13 can pass through-core hole or the hollow core slot slightly littler than its size, and is buckled on the other end of through-core hole or hollow core slot.
Fig. 2 is a fan cover and wiring layout after heat radiator is fixedly connected; Fan cover 2 peripheries are provided with four pillars 20; As shown in Figure 5, be equipped with first step hole 21 and second step hole 22 in each pillar 20, and the aperture in first step hole 21 is greater than the diameter of clinching spring head; And the aperture in second step hole 22 is less than the internal diameter (spring inside diameter is meant the minimum outer diameter of spring) of compression spring, and first step hole 21 is an annular surface level with 22 junctions, second step hole.
In order to be fixedly connected with fan cover 2, heat radiator 4 is being provided with four pilot holes 41 (not drawing among the figure) with four pillars of fan cover, 20 opposite position places, and the aperture of pilot hole 41 is identical with second step hole (22).Heat radiator 4 corresponding both sides can also be provided with a pair of support plate; The height of support plate is identical with the height of fan cover 2, helps fan cover and is fixedly connected better with heat radiator, not only can be used for supports fan lid; Can also fan and miscellaneous part be separated, so that the fan trouble free service.
During assembling, the pothook 13 of spring clinching 1 passes first and second stepped hole 21,22 of fan cover 2 successively, passes the pilot hole 41 of heat radiator 4 again; At last, pothook 13 is buckled in the bottom of heat radiator 4, simultaneously; Compression spring 10 1 ends lean the head 11 in spring clinching 1; The other end leans in the junction in fan cover 2 first step holes and second step hole, and at this moment compression spring 10 is in compressive state, and fan cover 2 is able to fix with heat radiator 4.
