Description

散热装置
技术领域
本发明涉及一种散热装置，特别是一种发光二极管散热装置。
背景技术
发光二极管(Light Emitting Diode，简称LED)灯具因其具有节能、环保等优点正得到广泛应用，但是，高亮度、高功率发光二极管发热量大，若不能及时将热量排出，发光二极管灯具会因温度的升高而导致其发光效率明显下降，甚至造成组件的损坏，目前，业界通常做法是在发光二极管电路板的下方贴设散热器以散发其热量，如美国专利US 6,517,218B2号即揭露了一种发光二极管散热器，其包括一基板及自该基板上延伸而出的多数散热鳍片，由基板吸收发光二极管的热量传到散热鳍片，依靠散热鳍片向周围辐射热量的方式进行散热。为了提高其散热效率，一般需增加散热鳍片数量或增大散热鳍片尺寸，但如此一来使得发光二极管散热器及整个照明装置的体积过大、过重。
发明内容
有鉴于此，有必要提供一种以有限的体积获得较佳的散热效果的发光二极管散热装置。
一种散热装置包括一散热器，该散热器包括若干自上而下堆叠排列的散热鳍片，这些散热鳍片沿排列方向相互间隔，每一散热鳍片的边缘开设有若干开口，这些开口上下对应形成若干气流通道，这些气流通道自上而下贯穿散热鳍片。
该散热装置竖直地放置于发光二极管模组的上方，由发光二极管模组产生的一部分热量辐射到该散热器底部的空气中并使得空气迅速升温，热空气通过气流通道可更为顺畅地向上方散发，加速散热，同时，通过气流通道的热空气还可与围成气流通道的散热鳍片的侧壁有更多更深地接触，可将散热鳍片的热量快速带走，进一步提高该散热装置的散热效率。
附图说明
图1是本发明实施例一的散热装置的立体图，其中一散热鳍片与该散热装置分离。
图2是图1的倒置组合图。
图3是本发明实施例二的散热装置的立体组合图。
图4是本发明实施例三的散热装置的立体组合图。
图5是本发明实施例四的散热装置的立体组合图。
具体实施方式
请参阅图1及图2，为本发明实施例一中的散热装置100，该散热装置100用于对作为光源的一发光二极管模组(图未示)进行散热。该散热装置100包括一散热器10、一穿插于散热器10中的热管30及一设于该散热器10、热管30的底部的方形导热板40。
所述散热器10包括若干圆片形散热鳍片12，这些散热鳍片12自上而下堆叠排列成一圆柱体，每一散热鳍片12的圆周边缘形成若干相互间隔的矩形开口120，这些矩形开口120沿圆周方向均匀排布，这些散热鳍片12的各开口120自上而下相互对应，使得该散热器10的圆周***形成若干上下连通的气流通道122。每一散热鳍片12上设有冲压形成的二通孔124及自通孔124的周围向上延伸的凸缘125，相邻散热鳍片12通过凸缘125自上而下相互间隔；该二通孔124分别邻近一开口120；所述散热鳍片12的通孔124自上而下相互对应形成二圆形通道以供热管30贯穿。该散热器10不限于散热鳍片12的组合，亦可为其它型式的散热器，如图3所示的散热器10a，该散热器10a包括一中心导热柱11a及自该导热柱表面向周围一体水平延伸的多数散热鳍片12a。
所述热管30呈U形，该热管30包括一中间的吸热段32及自该吸热段32两端向上延伸而成的二放热段35；该吸热段32用于与导热板40结合，该二放热段35贯穿连接于各散热鳍片12的通孔124中，从而将这些散热鳍片12串接成所述散热器10。
所述导热板40由高导热性的材料制成，如铜、铝，该导热板40的顶部开设一凹槽42，该凹槽42用于容纳该热管30的吸热段32。可在热管30的表面或凹槽42、通孔124中涂布导热胶，以便该热管30与导热板40、散热鳍片12焊接结合。所述散热鳍片12也可相互扣合形成于一体。
组装时，可先将散热鳍片12穿插焊接在热管30的放热段35上，接着将吸热段32焊接在导热板40的凹槽42中，然后将该散热装置100竖直地放置于所述发光二极管模组的上方，并使导热板40的底部与发光二极管模组贴设。工作时，发光二极管模组产生大量热量，其中一部分热量被导热板40吸收并通过热管30传递到散热器10上并进一步向四周散发，另一部分热量辐射到该散热器10底部的空气中并使得空气迅速升温，热空气从该散热器10的底部沿着散热器10的边缘向上散发；热空气通过气流通道122时可更为顺畅地向上方散发，加速散热，如箭头70所示，同时，通过气流通道122的热空气还可与围成气流通道122的散热鳍片12的侧壁有更多更深地接触，一方面可将散热鳍片12的热量快速带走，另一方面可将热量传导至该散热器10上半部分，充分利用上半部分的散热鳍片12进行散热，进一步提高散热效率。
上述实施例一中的开口120不限于矩形，也可为其他形状。如图4及图5中所示的散热装置200、300，该散热装置200的散热鳍片的开口220为圆弧形，散热装置300中的开口320为梯形，这些开口220、320相较开口120的面积大，由这些开口220、320构成的气流通道222、322比实施例一中的气流通道122具有更大的通道面积，能够容纳通过更多的热空气，且热空气与气流通道222、322周围的散热鳍片的接触面积也随之增加，因此，具有圆弧形开口220和梯形开口320的散热装置200、300相比散热装置100具有更高的散热效率。值得注意的是，若将开口220、320开得太大，也会相应地减少散热鳍片12的面积，对散热效率会有一定的不利影响。
上述实施例一中的散热鳍片12不限于圆形，也可为方形或其他形状。
