Embodiment

Core of the present utility model provides a kind of radiator and heat radiation module, be used for electronics, microelectronic device are dispelled the heat, improved by end surface shape structure the fin of radiator, make the dust that contains fibre composition be difficult between the end face of the adjacent fin of radiator air intake, putting up a bridge and piling up, thereby reached the purpose that obstruction takes place the fin that prevents radiator, and then the noise when having reduced electronic device works, improved the job stability of electronic equipment.The embodiment of the radiator that the utility model is provided below in conjunction with Figure of description is described in detail, so that those skilled in the art understand better.

Be without loss of generality, this paper is that example is elaborated with the radiator of notebook computer, but, the technical scheme that the utility model provides is equally applicable to the radiator on the elements such as the CPU, video card in the desktop computer, and other radiators small-sized or small electronic equipment, as various embedded systems etc.

As what introduced in this paper background technology, the main cause that causes the fin of the radiator of electronic equipment to stop up is, the dust that contains fibre composition is put up a bridge between the end face of the adjacent fin of radiator air intake easily and piled up, thereby fin (FIN) is stopped up.Therefore, how reducing that fibre composition puts up a bridge on the end face of adjacent fin is to solve the key that the fin of radiator stops up.

The dust that prevents to contain fibre composition is put up a bridge on the end face of adjacent fin and can be taked two kinds of measures: the one, and employing as described in the background art increases the mode of filter screen at air inlet, but, this mode is the problem (discuss in the background technology, do not repeat them here) of resolution system heat radiation fundamentally; Another kind of scheme is exactly the difficulty that increases the dust bridging that contains fibre composition, such as the distance between the end face that increases adjacent fin.But, if just increase the spacing between the adjacent fin simply, for example the spacing between the adjacent fin increases to 2mm from present 1mm, will certainly increase the volume of radiator, cause electronic equipment internal space anxiety, and under many circumstances, limit by the inner space, for example in notebook computer, the volume that increases radiator can't accomplish at all, so to increase the distance that the dust that contains fibre composition puts up a bridge on the end face of fin be worthless by increasing spacing between the adjacent fin simply.

In order to solve an above-mentioned difficult problem, the utility model provides a kind of technical scheme, fin to radiator finishes the structure improvement on the end face of air intake, under the prerequisite that does not change the spacing between the adjacent fin, increased the distance that the dust that contains fibre composition is put up a bridge on the end face of adjacent fin, increasing hardly under the condition of cost, solving the fin blocking problem that prevents radiator effectively.Specifically, the radiator that the utility model provides comprises a plurality of being parallel to each other and the fin that is provided with of 0.8-1.2mm at interval, the end face of the air intake of each fin has a plurality of protuberances and a plurality of depressed part, protuberance is identical with the depressed part shape and be provided with continuously along the length direction of the end face of fin, in the orientation of a plurality of described fins, the mutual stagger arrangement of the protuberance on the adjacent fin is arranged.Several specific embodiments of radiator have below been provided.

See also Fig. 2 and Fig. 3, Fig. 2 shows first kind of example structure schematic diagram of radiator that embodiment provides, and Fig. 3 is the fin structure schematic diagram of the radiator shown in Fig. 2, and this fin structure is first kind of embodiment of fin.As shown in Figure 2, radiator comprises a plurality of being parallel to each other and the A fin 100 that is provided with of 0.8-1.2mm at interval, and these A fins 100 are chained together by heat pipe 110.The concrete structure of A fin 100 as shown in Figure 3.Air intake at A fin 100, have a plurality of protuberances 111 and a plurality of depressed part 121 on its end face A, protuberance 111 is identical with depressed part 121 shapes, is semicircle, and protuberance 111 and depressed part 121 are provided with on the end face of A fin 100 along its length continuously.Again referring to Fig. 2, in the orientation of a plurality of fins, protuberance 111 on the A fin 100 respectively with adjacent fin on depressed part 122 be oppositely arranged one by one, simultaneously, the depressed part 121 on the A fin 100 also respectively with adjacent fin on protuberance 112 be oppositely arranged one by one.Specifically please in the lump referring to Fig. 4, this illustrate adjacent two fins in the present embodiment front view, this front view shows the closed state of two fins.Like this, on the end face A of the air intake of A fin 100, because its protuberance 111 is relative with the depressed part 122 of adjacent fin, so the distance between the protuberance of two nearest fins is the twice of fin pitch.With first shown in Fig. 2, the second and the 3rd A fin 101,102 and 103 (three adjacent A fins) are example, because the protuberance 111 on the A fin 101 is relative with the depressed part 122 on the 2nd A fin 102, and it is relative with protuberance 113 on the 3rd A fin 103, therefore the protuberance of two nearest fins is protuberance 111 on the A fin 101 and the distance between the protuberance 113 on the 3rd A fin 103, therefore, distance L 1 between the two is the twice of fin pitch L, thereby increased the distance that the dust that contains fibre composition is put up a bridge on the fin end face, increase the difficulty of dust accretions, realized the purpose that prevents that radiator fins from stopping up.In this scheme, the spacing between the fin can be set at 1.0mm.

protuberance

211 and 212 on the adjacent B fin, 212 and 213 S/3 that interlace arrange, like this, adjacent first, second, the third and fourth B fin 201,202, in 203 and 204, the protuberance of two nearest fins is protuberance 211 on the B fin 201 and the distance between the protuberance 214 on the 4th B fin 204, obviously, distance between the two is three times of fin pitch, therefore, contain distance that the dust of fibre composition puts up a bridge and also be three times of fin pitch on the fin end face, present embodiment has further increased the difficulty that dust is put up a bridge, and has reduced the chance of the fin obstruction of radiator.

Similarly, the S/4 that also can interlace of the protuberance on the adjacent fin end face arranges, like this, the distance on the nearest fin between the relative protuberance is four times of fin pitch; Specifically see also Fig. 8, this illustrates the front view of adjacent four fins described in the 4th embodiment.

More than among two kinds of concrete embodiment of radiator, the protuberance on the fin end face of radiator is curve shape, for example, among first kind of embodiment of radiator shown in Figure 3, protuberance 111 semicirculars in shape on the fin end face; In second kind of enforcement of radiator shown in Figure 6, the protuberance 211 on the fin end face is parabolic shape.But, above-mentioned two kinds of shapes of the protuberance on the fin end face only are exemplary explanation, be not used for specifically limiting the shape of the protuberance on the fin end face in the utility model, in fact, protuberance in the utility model on the fin end face can have multiple shape, for example shapes such as triangle, rectangle, square, trapezoidal or various trigonometric function curves; Should be appreciated that the simple deformation that also comprises them.

The above-mentioned radiator that improves the fin end face structure, mode by distance between the nearest fin end face that increases the radiator air intake, increase the difficulty that the dust that contains fibre composition is put up a bridge and piled up between the adjacent fin of radiator air intake, thereby realized preventing the purpose of the fin blockage phenomenon of radiator.
