Abstract

This invention relates to one dissipation, which comprises one bottom board and several dissipation fin slices on bottom board, wherein, each dissipating fin slice is set with parallel protruding parts and opens to form one gas channel; when gas flow enters flow channel onto protruding part or pass open with irregular torrent for change; the gas flows along each channel for multiple types to avoid gas flow fin slice surface stag and to increase gas flow router through dissipation device.

Description

Radiator

[technical field]

The present invention relates to a kind of radiator, particularly a kind of radiator that is applied to electronic component.

[background technology]

Along with the develop rapidly of electronic industry, the continuous lifting of electronic component (as the central processing unit) speed of service produces a large amount of heats during operation, itself and system temperature is raise, then the stability of its system of serious threat.For guaranteeing that electronic component can normally move, radiator is installed usually thereon, discharge the heat that it produces.

Traditional radiator generally comprises a base plate that contacts with electronic component, the planar fins of being located at the some rectangles on the base plate, and a fan that is installed on a fin top or a side.After the heat that electronic component when operation produces is absorbed by base plate, be dispersed in the surrounding environment with cooling electronic components by fin, the forced draft that the fan operation produces blows to fin scattering and disappearing with accelerated heat again.Thereby traditional radiator promotes heat dispersion, total area of dissipation that can strengthen radiator by the size or the arranging density of simple increase fin usually in order to increase area of dissipation as far as possible with the heat exchange area that increases between fin and the air-flow.Yet, when reaching the heat exchange area that increases radiator, the size that increases fin or arranging density will strengthen the air trapping degree of fin surface and the air drag of gas channel, cause air-flow can not blow fins group or flow velocity is slow, cause heat in time not to be pulled away, have a strong impact on the heat exchanger effectiveness between fin and the air-flow, and then the radiating efficiency of restriction radiator.

[summary of the invention]

In view of this, be necessary to provide a kind of improved radiator.

A kind of radiator comprises a base plate and is parallel to some radiating fins on the base plate that each radiating fin is provided with the protuberance and the opening of space, forms a gas channel between adjacent two radiating fins, and described protuberance is positioned at gas channel.

Compared to prior art, above-mentioned radiator adopts the radiating fin that is provided with protuberance and opening to be arranged on the base plate and forms gas channel.After air-flow enters runner, beat on protuberance or pass opening, airflow direction all changes and forms the irregular turbulent flow of direction, air-flow in each passage that opening part communicates along diversified path flows, so not only avoid air-flow on the surface of fin, to form delay, increase air communication simultaneously and cross the distance of radiator, thereby promote the heat exchanger effectiveness of air-flow and radiating fin, and then improve the cooling performance of radiator.

With reference to the accompanying drawings, the invention will be further described in conjunction with specific embodiments.

[description of drawings]

Fig. 1 is the part exploded view of first embodiment of radiator of the present invention.

Fig. 2 is the part exploded view of second embodiment of radiator of the present invention.

[embodiment]

Radiator of the present invention is to be used for central processing unit electronic components such as (figure do not show) is dispelled the heat.

See also Fig. 1, first embodiment of radiator of the present invention comprises a base plate 10, is located at the some radiating fins 20 on the base plate 10.Base plate 10 is to adopt good material such as copper, the aluminium etc. of heat conductivility to make, and its bottom surface contacts to absorb the heat that electronics unit is produced with electronic component (figure does not show).

Above-mentioned radiating fin 20 has a rectangular body 21, and a long spring folding of rectangular body 21 extends to form flanging 23.The body 21 of each radiating fin 20 is provided with several terrace with edge shape protuberance 25 and rectangular apertures 27, wherein protuberance 25 is stamping forming on body 21, so protuberance 25 at body 21 1 surperficial upper process, caves on body 21 another surperficial relative positions.These protuberances 25 and opening 27 are arranged at the middle part of body 21, be parallel to each other in the horizontal and the equi-spaced apart arrangement, and protuberance 25 are identical with opening 25 with the shape size of body 21 intersections.

Above-mentioned fin 20 equidistant parallels are arranged on the base plate 10, and all the flanging 23 of fins 20 constitutes planes (figure does not show), and base plate 10 upper surfaces can be fixed in by welding or mode such as bonding in this plane.20 of every two adjacent fins form a gas channel 29, at the import and export two ends near these passages 29 protuberance 25 and opening 27 are not set, so that the forced draft that air or fan (figure does not show) produce enters and flow pass 29.Beat after air-flow enters runner 29 on protuberance 25 or pass opening 27, airflow direction all can change, and forms the irregular turbulent flow of direction.Air-flow in each passage 29 that communicates along diversified path flows, so not only avoid air-flow on the surface of fin 20, to form delay, increase air communication simultaneously and cross the distance of radiator, thus the heat exchanger effectiveness of lifting air-flow and radiating fin 20, and then the cooling performance of raising radiator.

Fig. 2 is second embodiment of radiator of the present invention, above-mentioned radiator is except the radiating fin 20 among the protuberance 25 ' of radiating fin 20 ' and opening 27 ' and first embodiment different, and the arrangement mode of other parts and fin 20 ' is consistent with first embodiment all.Radiating fin 20 than first embodiment, the protuberance 25 ' of above-mentioned radiating fin 20 ' washes off out a rectangle partly by the body 21 ' of radiating fin 20 ', this rectangle partly is bent to parallel with body 21 ', thereby form and the same protuberance 25 ' of protuberance 25 effectiveness, simultaneously to the position that the washes off formation opening 27 ' on should body 21 '.

By above-mentioned two embodiment as seen, air or enter gas channel 29,29 ' by the forced draft that fan produces will be mobile along the direction that passage extends, under protuberance 25,25 ' stopping, air-flow single direct of travel originally becomes diversified, be looped around between each fin 20,20 ' by opening 27,27 ', fully contact with radiating fin, thereby take away heat on the radiator rapidly, realize the purpose of effective cooling electronic components.
