Abstract
The utility model relates to a reflective noise reduction radiator which comprises an upper cover body and a lower cover body, wherein the lower cover body is buckled with the upper cover body; a containing groove is arranged at the same side of the upper cover body and the lower cover body, and a fan is contained in the containing groove; a sidewall is arranged on one side of the lower cover body, which is different from the containing groove; a plurality of spacer plates which are parallel to the sidewall are arranged in the containing groove; a plurality of air channels which are communicated with the containing groove are arranged among the spacer plates; the air channels are divided into a right half part and a left half part, the right half part is close to the fan, the left half part is far from the fan and the widths of the right half part and the left half part are different. Through the arrangement, when noises come from the right half part to the left half part, sound waves of the noises can generate reflection at the width transforming position so as to eliminate a part of energy. Thus the aim of noise reduction is achieved.
Description
Technical field
The relevant a kind of heating radiator of the utility model, thus especially relevant a kind of the generation in the air channel by sound wave reflected the noise reduction heating radiator of reaching reduction noise purpose.
Background technology
Computer is the electronics and IT products that the present information people is dependent on most, and we know when actions of computer, is to carry out by central processing unit entirely.When carrying out action, must produce high temperature, and when producing high temperature,, will make the action of computer unsettled situation occur if it is not dispelled the heat timely.And computer mainly is the running by fan, keeps watch and blows over heat radiator, thermal conductance is gone out and reaches radiating effect.Therefore the execution stability of the design of fan and computer cpu is closely bound up in the heat abstractor.Especially in notebook computer, because the volume of notebook computer is less, and its thickness is too little, and the distance between each components and parts is less, so the more direct operation stability that has influence on computer of the quality of its heat dispersion.
As everyone knows, heat dissipation problem is directly connected to the stability of notebook computer, solve bad heat radiation and can cause the serious decline of computer performance, and influence product reliability, when serious even also can influence serviceable life of notebook computer miscellaneous part, and the deadlock of many unknown causes also usually is due to the heat dissipation problem.
Concerning desktop computer, roomy and draughty cabinet, large-area heat radiator, powerful fan add rational layout, and it is simple relatively to solve heat dissipation problem.And for the notebook computer that develops towards the ultra-thin direction of ultralight, because the restriction of volume is increasing, each parts integrated level is also more and more higher, and heat dissipation problem solves just more thorny.
As shown in Figure 1, between the lid 2,3, the wind-force that electric fan 1 rotation produces spread out of by the air channel on the lower cover 3 31, with this high-temperature gas in computer is dispelled the heat about fan 1 was arranged at.For efficiently radiates heat, especially the acting in conjunction by fan and air channel makes the notebook computer efficiently radiates heat, generally the method for the rotating speed by increasing fan is carried out, yet by this method, will inevitably increase the noise that wind-force that fan produces is produced by the air channel time, this also is unacceptable for most user, how to reduce the noise that fan produces and become current industry subject matter to be solved under the prerequisite that does not reduce rotation speed of the fan.
The utility model content
The purpose of this utility model is to provide a kind of noise reduction heating radiator, and it can be under the situation that does not reduce rotation speed of the fan, thereby reaches the effect that reduces noise by the transformation to the air channel.
The purpose of this utility model is achieved in that a kind of noise reduction heating radiator, the lower cover that comprises upper cover body, is interlocked with upper cover body, phase the same side of upper and lower cover body has accepting groove, one fan is contained in the above-mentioned accepting groove, has sidewall with the different side of accepting groove on the lower cover, and have some dividing plates in it with parallel sidewalls, form some air channels that are connected with accepting groove between the dividing plate, above-mentioned air channel is divided near the right-hand part of fan and away from the left side of fan, and right-hand part is different with the width of left side.
Compared with prior art, the beneficial effects of the utility model are: the different reflexs that produce of right-hand part with left side width by the air channel effectively reduce the noise that fan produces.
Description of drawings
Fig. 1 is the three-dimensional exploded view of the noise reduction heating radiator of prior art.
Fig. 2 is the three-dimensional exploded view of the utility model noise reduction heating radiator.
Fig. 3 is the vertical view of the lower cover of the utility model noise reduction heating radiator.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
See also shown in Figure 2, the utility model noise reduction heating radiator comprises that a side of upper cover body 1, upper cover body 1 has accepting groove 11, one lower cover 2 can be interlocked with upper cover body 1, and offers accepting groove 21 corresponding to the position of above-mentioned accepting groove 11, and fan 3 is arranged in above-mentioned accepting groove 11 and 21.Extend upward sidewall 22 around the lower cover 2, on lower cover 2, have the dividing plate 24 that several interlacing that be arranged in parallel with sidewall 22 are provided with, the some air channels that are connected with accepting groove 25 of formation between each dividing plate 24 with the different side of accepting groove 21.After lid 1,2 combines up and down, derive by above-mentioned air channel 25 by the wind-force that fan 3 is produced.Please cooperate consult shown in Figure 3, because the width difference of the diverse location of dividing plate 24, so above-mentioned air channel 25 is divided into the left side 253 that the right-hand part 251 of close fan 3 reaches away from fan, right-hand part 251 is different with the width of left side 253, and the width of left side 253 is a bit larger tham right-hand part 251.Equally, if being slightly wider than left side 253, right-hand part 251 equally also can reach identical effect.
In use, up and down lid 1,2 combines, and the noise sound wave that fan 3 is produced 25 passes through from the air channel, and the junction of 25 left right-hand part 253,251 in the air channel can produce reflex, thereby reduces noise.
In sum, the utility model has been finished designer's purpose, and the noise reduction heating radiator can be under the situation that does not reduce rotation speed of the fan, and the different designs by air channel width reaches the purpose that effectively reduces fan noise.
