Each exemplary embodiment of the present invention is described below with reference to accompanying drawings.
Fig. 1 is the 3-D view of the radiator illustrated according to a preferred embodiment of the invention.As shown in Figure 1, radiator is according to this preferred embodiment of the invention assembled by multiple mutually the same radiating fin, and these radiating fins are arranged side by side, to form coolant circulation passage between adjacent heat radiation fin.This radiator may be used in electronic product such as notebook, and correspondingly, in this case, coolant is air.In actual use, the bottom B of this radiator attaches on the chip of such as notebook, one fan can be arranged in radiator side with the side blow facing to radiator, with the heat making air-flow to be taken away radiator by the circulation passage between radiating fin, correspondingly, the heat of chip is also pulled away.
Further describe the concrete structure of radiator referring now to Fig. 2-4, wherein Fig. 2 is the vertical view that the radiator shown in Fig. 1 is observed from top T; Fig. 3 is the 3-D view of the single radiating fin of the radiator shown in Fig. 1; Fig. 4 is the partial enlarged view of Fig. 2, but adds a schematic fan 5 for convenience.
As shown in Figure 2, radiator according to a preferred embodiment of the invention comprises the multiple radiating fins be arranged side by side, two adjacent spaced apart certain distances of radiating fin are to form coolant circulation passage, wherein, described multiple radiating fin has the first radiating fin 1, second radiating fin 2 adjacent one another are and the 3rd radiating fin 3, formed between first radiating fin 1 and the second radiating fin 2 between first coolant circulation passage 12, second radiating fin 2 and the 3rd radiating fin 3 and form the second coolant circulation passage 23.
It should be noted that; in the preferred embodiment of the present invention; first radiating fin 1, second radiating fin 2 is identical with arrangement with the structure of the 3rd radiating fin 3; but in alternative embodiments; they also can be different from each other; therefore; in this article; carry out " first ", the differentiation of " second " and " the 3rd " be only used to describe convenience; and do not mean that those parts of relevant to it (it is representative) are inevitable identical or different; correspondingly, first ", " second " and " the 3rd " does not form the restriction to protection scope of the present invention yet.Further; in this embodiment of the invention; virtually all radiating fin is all identical; but, it is envisioned that these radiating fins can be different from each other; or; only the first radiating fin 1, second radiating fin 2 and the 3rd radiating fin 3 mutually the same, or more or less radiating fin is identical, and these configuration modes all drop in protection scope of the present invention.
With reference to Fig. 2 and 3, a radiating fin in multiple radiating fin, i.e. the second radiating fin 2, there are two kinks 20 extended towards the first radiating fin 1, in each kink 20, form through hole 200 (shown in Figure 3), communicate with each other to make the first coolant circulation passage 12 and the second coolant circulation passage 23.Like this, as shown in the schematic diagram of the air-flow F in Fig. 4, the air-flow F blown out from the fan 5 on radiator side can intercommunication between adjacency channel, thus, even if the air quantity that fan 5 is blown in each passage between radiating fin is not identical with wind speed, if to make otherwise to cause the gas flow temperature in each passage and speed not identical under the mutual disconnected situation of each passage, and then make the heat-sinking capability of each radiating fin of radiator not identical, but, in the present invention, because each passage is by through hole 200 intercommunication, and there are two through holes (namely there are two kinks) in single radiating fin, therefore first coolant and air-flow can enter another adjacent passage at first kink place from first passage, and mix with the air-flow in this another passage, then the air-flow in this mixed air-flow and/or this another passage former is got back in first passage at second kink place again, thus realize good mixed flow even temperature effect, and finally make the heat-sinking capability of the various piece of radiator (each radiating fin) be tending towards identical.
In order to improve the mixed flow even temperature effect of the air-flow between adjacent two passages, preferably, as shown in Figure 3, the area of through hole 200 should be large as far as possible, preferably roughly the same with the area of kink 20 (a little bit smaller a little); And, as shown in Figures 3 and 4, kink 20 should be approximately perpendicular to the flow direction of the coolant F in coolant circulation passage, to make the direction of the through hole 200 in kink 20 roughly the same with the flow direction of coolant F or parallel, enter in another passage via through hole to be conducive to coolant from a passage; And, as shown in Figure 3, single radiating fin has 2 kinks 20 and can flow into another passage from a passage to make coolant, then turn back to again after mixing with the coolant in another passage in former passage, certainly, more kink can be had to increase the interoperability of the coolant in two passages; And, as shown in Figure 4, spacing G1 between adjacent two radiating fins in kink place does not have 1/2nd of spacing G2 between adjacent two radiating fins in the position of kink along the coolant flow direction in passage in kink upstream, like this, only about half of coolant in a passage can enter in another adjacent passage, the half of (before or after the mixing) coolant in this another adjacent passage can enter in former passage, thus with the temperature being conducive to balanced adjacent two circulation passages, flow or flow velocity.On the other hand, it should be noted that, the present invention is not limited to the embodiment of radiator shown in the drawings, such as, only 1 kink or more than 2 kinks can be had, kink can and be not orthogonal to coolant flow direction, but can with coolant flow direction in an acute angle or obtuse angle, the spacing G1 at kink place between adjacent two radiating fins can be greater than or less than at 1/2nd of the spacing G2 not having kink place.
The radiator how manufactured as shown in Figure 1 is described referring now to Fig. 5.According to the method for manufacture of the present invention radiator as shown in Figure 1, comprise the following steps: prepare the radiating fin that each is single, assemble all radiating fins to form radiator as shown in Figure 1, the step wherein preparing single radiating fin comprises: provide a flat radiating fin blank (step S1); Required such as two through holes 200 (step S2) are gone out by means of such as stamping tool in appropriate location on this blank; And by the bend portions around through hole 200, such as complete 90 degree, with formed as shown in Figure 3 or step S3 shown in kink 20 (step S3).
Can predict, in step s 2, the number of the distance between through hole 200 and through hole 200 can adjust accordingly according to the Distance geometry number between the kink of the radiating fin of expection; In step s3, can angle of bend be adjusted thus adjust the angle between kink and coolant flow direction.
As above can find out, in a preferred embodiment of the invention, can be facilitated by simple punching, discounting (bending) step, formation heat-sinking capability is strong at low cost, dispel the heat uniform radiator.On the other hand, if adopt traditional casting technique or process for machining to form radiator fins of the present invention, then this casting technique or process for machining are comparatively complicated due to the existence of kink and through hole, and product quality is also difficult to ensure, therefore, the method for manufacture radiator of the present invention will have obvious cost advantage compared to this traditional casting method.In addition, have benefited from the simple structure of radiator of the present invention, its manufacture method also correspondingly becomes simple.
It should be noted that, radiating fin of the present invention can use with radiating fin combination of the prior art, such as, the radiating fin of one or more radiating fin as shown in Figure 3 according to the present invention and other radiating fin of the prior art such as straight-plate-type can be carried out assembling to form a radiator.Correspondingly, manufacture method of the present invention also can be combined with manufacture method of the prior art.
Finally, should also be noted that, although with reference on the basis of each embodiment, the present invention has been described in the description and has been illustrated in the accompanying drawings, but it will be appreciated by those skilled in the art that, above-described embodiment is only preferred embodiment, and some technical characteristic in embodiment may not be required for the specific technical problem of solution, thus not or can omit these technical characteristics and the solution of non-influence technique problem or the formation of technical scheme; And the feature of an embodiment, key element and/or function suitably mutually can combine, combine or coordinate with the feature of other one or more embodiment, key element and/or function, unless this combination, combination or coordinate obviously can not be implemented.
