具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳的实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
如图1和图2所示，在一实施例中，提供一种无线充电设备10，该无线充电设备10中具有多个能够散热的风道，散热效果较好。该无线充电设备10对待充电设备20充电时，多个散热风道不仅能够降低自身的温度，气流能够流经待充电设备20的朝向无线充电设备10的一侧，使得待充电设备20的温度能够降低。
如图5a所示，在一实施例中，无线充电设备10包括外壳100和位于外壳100内的线圈模组200、散热器300、风扇400和电路组件500。
如图4a和图5b所示，在一实施例中，外壳100包括第一盖体110和第二盖体120，第一盖体110和第二盖体120盖合时形成无线充电设备10的容纳空间。在一实施例中，第一盖体110为平板状结构，第二盖体120为开口的盘子状结构，且第二盖体120具有一定的深度。第一盖体110盖合第二盖体120，使得无线充电设备10具有容纳空间。在该容纳空间中，依次设有线圈模组200、散热器300、风扇400和电路组件500。
如图4a至图4c所示，在一实施例中，风扇400和电路组件500之间存在缝隙440。第一盖体110上开设有第一进风口111，第二盖体120上开设有第二进风口121和出风口122。当风扇400工作时，带动空气(气流)从第一进风口111进入，并从出风口122流出，形成流经线圈模组200的第一风道11(参考图4d)；以及带动空气从第二进风口121进入，并从出风口122流出，形成流经缝隙440的第二风道12(参考图4e)。第一风道11内的气流流经线圈模组200，能够降低线圈模组200的温度。第二风道12的气流流经风扇400和电路组件500之间的缝隙440，能够降低电路组件500的温度。与单条散热风道相比，本实施例的散热效果较好。
可以理解的是，第二进风口121和出风口122形状和大小可以相同也可以不同，因二者所处位置不同，使得第二进风口121具有进风功能，出风口122具有出风功能。
如图2至图4a所示，在一实施例中，第一盖体110的表面设有支撑元件114，在一实施例中，支 撑元件114为环形凸条。第一进风口111位于支撑元件114所围设的区域内。支撑元件114所围设的区域可以为圆形、椭圆形或方形等，用于支撑待充电设备20。待充电设备20放在第一盖体110上时，支撑元件114的部分结构被待充电设备20覆盖，即支撑元件114所围设的区域中的至少部分区域未被待充电设备20覆盖。环境中的气流可以进入支撑元件114所围设的区域中的被暴露的区域，并通过第一进风口111进入无线充电设备10内部。通过风扇400的工作，环境中的气流不断的进入支撑元件114所围设的区域中的未被待充电设备20覆盖的区域，待充电设备20、支撑元件114和第一进风口111一起在待充电设备20的朝向无线充电设备10的一侧形成涡旋增压效果，能够降低待充电设备20的朝向无线充电设备10的一侧的温度。
如图4a和图6所示，在一实施例中，第一进风口111包括中心口112和环绕中心口112的环口113。第一盖体110为圆板形结构，中心口112位于第一盖体110的圆心，环口113位于中心口112的外围。环口113可以为弧形的条状口，也可以为方形口，也可以为其他形状的口，在此不做限定。中心口112和环口113均位于支撑元件114围设的区域内。
如图4a、图5b和图7所示，在一实施例中，线圈模组200的中心开设有第一通孔210，外界的气流从中心口112进入外壳100，并流经第一通孔210后进入风扇400内，通过风扇400的扇叶的转动使得气流通过出风口122排出无线充电模组，形成第一风道11，并带走线圈模组200的热量。
如图4a、图5b和图8所示，在一实施例中，散热器300位于线圈模组200和风扇400之间。线圈模组200固定于散热器300的朝向第一盖体110的一侧，风扇400固定于散热器300的朝向第二盖体120的一侧。散热器300的朝向线圈模组200的一侧设有第一容纳槽320，且所述第一容纳槽320的槽底开设有第二通孔310。在一实施例中，第一容纳槽320为圆形槽，线圈模组200的边缘为圆形，使得线圈模组200能够容纳于第一容纳槽320内。第一通孔210位于第二通孔310的范围内，使得的气流流经第一通孔210后能够从第二通孔310流向风扇400。在一实施例中，第一通孔210和第二通孔310均为圆形孔，中心口112、第一通孔210和第二通孔310同轴，且第一通孔210的直径小于第二通孔310的直径。第二通孔310直径较大，一方面使得第一通孔210内的气流能够通过第二通孔310流入风扇400，另一方面减小线圈模组200与散热器300的叠层设置的面积，使得线圈模组200容易散热。
如图4a所示，在一实施例中，当风扇400工作时，外界的气流从中心口112进入外壳100内，并依次流经第一通孔210、第二通孔310和风扇400，并从出风口122排出外壳100之外，形成第一风道11，以带走线圈模组200的热量。
如图9和图10所示，在一实施例中，散热器300位于线圈模组200和风扇400之间。散热器300可以粘结于第二盖体120的内表面，也可以通过螺栓或螺钉固定于第二盖体120。散热器300的朝向风扇400的一侧设有第二容纳槽330，风扇400能够容纳于第二容纳槽330内，且风扇400通过螺钉或螺栓固定于第二容纳槽330内。在一实施例内，第二容纳槽330内设有凸柱360，凸柱360的数量为多个，风扇400安装于第二容纳槽330内时，风扇400和第二容纳槽330的槽底之间存在间隙340，间隙340的深度即为凸柱360的高度。风扇400和第二容纳槽330之间的间隙340使得气流能够流过而进入风扇400内。
如图8至图10所示，在一实施例中，散热器300的一侧为密封结构，一侧开设有导风口350，导风口350和凸柱360间隔设置，数量为多个。风扇400安装于第二容纳槽330内时，凸柱360使得风扇400和散热器300之间存在间隙340，间隙340与导风口350连通。环口113、导风口350、间隙340、风扇400以及出风口122形成第三风道13(参考图4f)。当风扇400工作时，环境中的气流通过环口113进入外壳100内，通过导风口350进入散热器300和风扇400之间的间隙340，从而进入风扇400内部，通过风扇400的扇叶的运转，第三风道13的气流通过出风口122排出外壳100之外，从而带走外壳100内的热量。可以理解的是，散热器300的靠近出风口122的一侧为密封结构，具体为散热器300在该处不开设导风口350，防止外界的气流从中心口112或环口113进入外壳后直接从出风口122流出。
在一实施例中，散热器300的材质为金属，比如铝、铁、钢或导热合金等。散热器300与线圈模组200接触，能够将线圈模组200的热量传导至环境中，便于线圈模组200的散热。
如图11和图12所示，在一实施例中，风扇400的扇叶被隐藏，但其实风扇400内部存在扇叶。风扇400开设有第一入风口410、第二入风口420和侧风口430。第一入风口410位于风扇400的朝向散热器300的一侧，第一入风口410的形状为圆形，大小与第二通孔310相匹配，即第一入风口410的直径与第二通孔310的直径相等或基本相等。侧风口430开设于风扇400的侧面，开口朝向出风口122，使得风扇400运转时排出的气流能够通过侧风口430流向出风口122，从而排出外壳100之外，并带走外壳100内的热量。第二入风口420开设于风扇400的背向散热器300的一侧，第二入风口420的数量为多个，形状可以为规则的圆形、方形或弧形，也可以为不规则的开口，在此不做限定。
在一实施例中，散热器300的为密封结构的一侧设有导风板380，导风板380位于散热器300的背向线圈模组200的一侧。相邻的导风板380之间形成气流的通道，通道一端对接侧风口430另一端对接出风口122，从侧风口430流出的气流能够在通道内流通，并流向出风口122。从侧风口430流出的气流已吸收线圈模组200和电路组件500等的热量，温度高于外界的空气的温度。导风板380能够引导侧风口430流出的气流的流动方向，并将气流引流至出风口122，避免从侧风口430流出的气流在外壳100内没有规则的流动，从而影响无线充电设备10的散热。
如图4a所示，在一实施例中，当风扇400工作时，外界的气流从中心口112进入外壳100内，并依次流经第一通孔210、第二通孔310、第一入风口410和侧风口430，并从出风口122排出外壳100之外，形成第一风道11，并带走线圈模组200的热量；外界的气流从第二进风口121进入外壳100内，并依次流经风扇400与电路组件500之间的缝隙440、第二入风口420和侧风口430，并从出风口122排出外壳100之外，形成第二风道12，并带走电路组件500的热量；外界的气流从环口113进入外壳100内，并依次流经导风口350、风扇400与散热器300之间的间隙340、第一入风口410和侧风口430，并从出风口122排出外壳100之外，形成第三风道13，并带走散热器300的热量。风扇400工作时，第一风道11、第二风道12和第三风道13同时存在，使得外壳100内的热量能够较快的排出外壳100之外，且支撑元件114、第一进风口111和待充电设备20的朝向无线充电设备10的一侧一起形成涡旋增压效果，使得待充电设备20能够较快地散热。
如图13至图15所示，在一实施例中，电路组件500包括相互连接的电路板510和屏蔽罩520。电路板510位于电路组件500的朝向第一盖体110的一侧，屏蔽罩520位于电路组件500的朝向第二盖体120的一侧，屏蔽罩520与第二盖体120的底部可以贴合，也可以设有填充材料，使得气流无法在屏蔽罩520和第二盖体120的底部之间流动，避免气流从第二进风口121进入外壳100后直接从屏蔽罩520和第二盖体120的底部之间流向出风口122。输入电缆600穿透第二盖体120，进入外壳100内，电路板510于输入电缆600连接，电路板510与线圈模组200、风扇400等位于外壳100内的电子元件电性连接，使得外接电源能够为电路板510、线圈模组200以及风扇400等供电。
在一实施例中，电路组件500与散热器300固定连接，可以通过螺栓或螺钉连接。电路组件500盖设第二容纳槽330，使得风扇400位于第二容纳槽330的槽底和电路板510之间，且风扇400和第二容纳槽330的槽底之间因凸柱360的支撑而存在间隙340，该间隙340与导风口350连通。且风扇400与电路板510之间存在缝隙440。风扇400工作时，外界的气流通过环口113依次流经导风口350、风扇400与第二容纳槽330的槽底之间的间隙340、第一入风口410、侧风口430并从出风口122排出外壳100之外，形成第三风道13；外界气流通过第二进风口121依次流经风扇400与电路板510之间的缝隙440、第二入风口420、侧风口430并从出风口122排出外壳100之外，形成第二风道12。
如图16和图17所示，在一实施例中，第二进风口121和出风口122均为第二盖体120的侧壁上开设的条形口，该条形口的数量为多个，环绕第二盖体120的侧壁一周。风扇400工作时，条形口的靠近风扇400与电路板510之间的缝隙440的部分会有气流进入，定义靠近缝隙440且有气流进入的条形口为第二进风口121；条形口的靠近侧风口430的部分会有气流流出，定义靠近侧风口430且有气流流出的条形口为出风口122。可以理解的时，条形口可以环绕第二盖体120的侧壁的一周，也可以为零散分布的几个条形口，但需满足风扇400工作时有气流进入外壳100并流经风扇400和电路板510之间的缝隙440，且需满足有气流从条形口流出外壳100。
在一实施例中，线圈模组200和电路组件500中的至少一个的表面贴有储热材料，储热材料能够 吸收热量，使得线圈模组200或电路组件500的温度升温较慢，从而避免线圈模组200或电路组件500出现高温现象。
在一实施例中，线圈模组200和电路组件500中的至少一个的表面贴有隔热材料，使得线圈模组200或电路组件500的热量能够向固定方向传递，便于散热，同时也避免线圈模组200或电路组件500朝向其他发热元件传递热量。
本申请的无线充电设备10，包括三条散热风道，分别为第一风道11、第二风道12和第三风道13。外界的气流从中心口112进入外壳100内并依次流经第一通孔210、第二通孔310、第一入风口410、侧风口430并从出风口122排出外壳100之外，形成第一风道11，并带走线圈模组200的热量；外界的气流从第二进风口121进入外壳100内并依次流经风扇400与电路组件500之间的缝隙440、第二入风口420、测风口并从出风口122排出外壳100之外，形成第二风道12，并带走电路组件500的热量；外界的气流从环口113进入外壳100内并依次流经导风口350、风扇400与第二容纳槽330的槽底之间的间隙340、第一入风口410、侧风口430并从出风口122排出外壳100之外，形成第三风道13，并带走散热器300的热量。
多条散热风道能够提高无线充电设备10的散热效率，可以支持高功率无线充电。第一盖体110上的中心口112和环口113为第一风道11和第二风道12提供进风口。支撑元件114、中心口112和环口113的设计使得待充电设备20的朝向无线充电设备10的一侧与无线充电设备10之间形成涡旋增压效果，从而能够使得待充电设备20能够散热。风扇400一侧开设有第一入风口410，另一侧开设有第二入风口420，双入风口的设计使得第一风道11、第二风道12以及第三风道13能够分别形成完整的散热通路，其中从中心口112和环口113进入外壳100的气流流经第一入风口410，从第二进风口121进入外壳100的气流流经第二入风口420。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
