Description

导风件
技术领域
本发明涉及一种导风件。
背景技术
在电子装置，如服务器内，通常会装设有若干风扇，以给电路板上的发热电子元件进行散热。这些风扇吹出的风流的大部分会直接吹向电路板的上方，给发热电子元件散热；而还有一小部分的风流则会吹向电路板的下方，其散热效果一般，风流没有得到充分的利用。
发明内容
鉴于以上，有必要提供一种能够提高风流利用率的导风件。
一种导风件，包括一导风部及若干挡片，该导风部包括一长形的底壁及由该底壁的前侧向上并向后倾斜延伸的一长形的导风壁，该导风壁开设有若干通风槽，每一挡片的前端由下向上并向后倾斜形成一斜面，这些挡片的设有斜面的一端可选择地***该导风壁的对应通风槽，该导风部还包括两由该导风壁朝向该底壁的一侧向后延伸出的具有弹性的卡脚，该两卡脚的中部相向弯折分别形成一弧形的卡扣部。
相较现有技术，该导风件可装设于一电子装置的电路板正对风扇的一侧，该导风件的导风壁及***导风部的挡片的斜面可将风流拦住并向上导至电路板的上方，从而提高了风流的利用率及电子装置的散热效率；同时，使用者可根据不同的电路板上的发热电子元件的排布情况及散热需求选择性的将这些挡片***该导风部的不同位置，使该导风部上的正对发热电子元件的通风槽不被***挡片，从而将风流导向至发热电子元件的正下方，以保证发热电子元件下方的通风及散热。

具体实施方式
请参照图1与图2，本发明导风件40的较佳实施方式，可用于一电子装置内。该电子装置包括一底板10、一电路板20及若干风扇30。这些风扇30装设于该底板10上。该底板10上凸设有若干具有螺孔121的固定柱12(图2中只显示最靠近风扇30的两固定柱12)。该电路板20对应该底板10上的这些固定柱12的螺孔121设有若干穿孔23(图中只显示两穿孔23)。若干螺丝分别穿过该电路板20上的穿孔23并锁入该底板10上的对应固定柱12的螺孔121，将该电路板20固定于该底板10上并位于这些风扇30的后方。该电路板20上装设有一发热电子元件25。
请参照图3与图4，该导风件40包括一导风部41及若干挡片47。
该导风部41包括一长形的底壁42、由该底壁42的前侧向上并向后倾斜延伸的一长形的导风壁43及两由该导风壁43朝向该底壁42的一侧向后延伸出的具有弹性的卡脚45。该导风壁43开设有若干沿其长度方向间隔的通风槽431。该底壁42于每一通风槽431的正下方，以及该导风壁43朝向该底壁42的一侧于每一通风槽431的正后方分别设有一贯穿至该底壁42的后侧与该导风壁43的后侧的长形的凹槽44。每一凹槽44于邻近后端处凹设有一弧形的卡槽442。该两卡脚45呈片状，分别由该导风壁43的邻近两端处向后延伸出。该两卡脚45的中部相向弯折分别形成一弧形的卡扣部451。该两卡扣部451之间的距离大致等于该电路板20上的邻近这些风扇30的两固定柱12之间的距离。该两卡脚45的末端相向弯折分别形成一倾斜的引导面453。每一卡脚45背向另一卡脚45的一侧于卡扣部451于引导面453之间凸设有若干防滑条455。
每一挡片47大致呈一梯形，其前端由下向上并向后倾斜形成一斜面471。该斜面471的倾斜角度等于该导风部41的导风壁43的倾斜角度。每一挡片47的顶部与底部分别于靠近后端处凸设一弧形的凸起473。每一挡片47的两侧分别于靠近后端处设有一便于使用者手指扣持的凹槽475。
这些挡片47可根据需要选择性地由该导风部41的后侧***该导风部41内，使每一挡片47的顶部与底部分别***该导风部41的底壁42与导风壁43的对应凹槽44内，且每一挡片47的顶部与底部的凸起473分别卡入对应凹槽44的卡槽442内。此时，每一挡片47的设有斜面471的一端***该导风壁43的对应通风槽431，每一挡片47的斜面471与该导风壁43背向该底壁42的一侧位于同一平面。
请再次参照图1与图2，要将该导风件40装设于该电子装置内时，首先将该导风件40置于该底板10上并位于该电路板20与这些风扇30之间，使该导风件40的导风壁43面向这些风扇30，该导风件40的两卡脚45的引导面453分别正对该底板10上的邻近这些风扇30的两对应固定柱12。根据该电路板20上的发热电子元件25的位置调整这些挡片47，使该导风部41与该发热电子元件25正对的位置不装设挡片47，而其他位置则***挡片47。从而，该导风部41位于该发热电子元件25正前方处的通风槽431保持畅通，而该导风部41位于该发热电子元件25两侧的通风槽431则被挡片47阻挡。向后推动该导风件40，使该导风件40的两卡脚45***该电路板20的下方，该两卡脚45的引导面453分别抵接该底板10上的对应固定柱12，并逐渐滑过该两对应的固定柱12并带动该两卡脚45相向移动发生弹性变形。继续向后推动该导风件40，直至该两卡脚45的卡扣部451分别正对该两对应的固定柱12，该两卡脚45弹性恢复使该两卡扣部451分别卡置于该两对应的固定柱12。从而，该导风件40被固定于该底板10。此时，该导风件40的导风壁43的后侧边抵接于该电路板20的前侧。
该电子装置工作时，这些风扇30吹出的风流一部分直接吹向该电路板20的上方，一部分沿着该导风部41的导风壁43及挡片47前侧的斜面471由下向上吹至该电路板20的上方，这两部分风流均可流经该电路板20上的发热电子元件25及其它电子元件并对发热电子元件25及其它电子元件进行高效的散热。同时，这些风扇30吹出的风流还有一小部分穿过该导风部41的导风壁43上的未被挡片47阻挡的通风槽431而吹向该电路板20的发热电子元件25的下方，从而可以从底面给发热电子元件25及电路板20散热。由于该导风件40将大部分的本将要流向电路板20下方的风流拦住并导向电路板20的上方，从而提高了风流的利用率及电子装置的散热效率。同时，由于这些挡片47可拆卸，使用者可根据不同的电路板上的发热电子元件的排布情况及散热需求选择性的将这些挡片47***该导风部41的不同位置。
要取出该导风件40时，只需相向按压该导风件40的两卡脚45的设有防滑条455处，使该两卡脚45的卡扣部451分别脱离对应的固定柱12，即可向前拔出该导风件40。
在其它实施方式中，该导风件40可省去该两卡脚45而通过其它方式固定于该底板10，如通过与底板10之间的卡扣或螺丝锁固等。
在其它实施方式中，该导风部41的底壁42及导风壁43上的凹槽44可以省去，这些挡片47的设有斜面471的一端可直接***该导风壁43上的对应通风槽431，而依靠挡片47与对应通风槽431之间的摩擦力而将挡片47固定。
