为了进一步加快推送液体至冷却液收集器过程中液体与外界空气的热交换，本实施例中气流发生器105可以为涡流发生器；所述涡流发生器在该段管道中冷却液的热力作用下形成涡流。
本实施例中涡流发生器产生涡流的方式有多种，优先地方式为：所述涡流发生器的底部设有进气口，所述进气口的进气方向与所述底部侧边相切；在冷却液的热力作用下，所述涡流发生器从底部的进气口吸入空气，气体沿所述涡流发生器内壁环形上升形成涡流。
为了更好地促使涡流快速形成，涡流发生器的内壁设计成椭圆形，出口设计成翁形，气流沿进气口相切进入内壁，沿内壁在热力作用下螺旋上升，多条进气道同一方向旋转，形成强力涡流极速上升。椭圆形的内壁，促使进口气流在外形作用下极速形成涡流，在出口收窄的情况下，有助于气流形成密集涡流，对气流起到极速拉升作用。
为了能够进一步加快第二管道内液体散热，需要增大管道与涡流的接触面积，因此，上述第二管道104的至少一段为环形管道，即位于涡流发生器内的一段或多段管道为环形管道。优先地，本实施例中环形管道设置在所述涡流发生器的内壁上。
为了有效让散热片内已经过热的液体排出，且冷液体循环进入，利用汽化气体膨胀的原理，设计散热片的液体排出管道的内径大于涡流发生器液体进入管道的内径5倍以上，这样可以防止气流混入液体无效排出，可以在气体压力下，有效排出液体。具体地，在本实施例中，当所述第二管道由依次连接的：所述涡流发生器的液体排出管道、位于所述涡流发生器内的至少一段环形管道、所述涡流发生器的液体进入管道和所述散热片的液体排出管道构成时；所述散热片的液体排出管道的内径大于五倍涡流发生器的液体进入管道的内径。
为了使得第二管道104中热液体尽速降温，将涡流发生器内的管道（例如上述环形管道）内径尽量设计小，而管道长度尽量长，形成涡流发生器体积尽量大，这样与涡流气流增大接触面，可以使液体在尽快冷却。
实施例二：

本实施例第一单向阀在液体推力作用下打开，以便液体自动流入液体收集器，一旦液体收集完成，单向阀由于液体的压力作用将进口密封，从而达到阻止液体倒流。
为了使的收集器中的液体能够顺利流入散热片，本实施例散热装置，在所述冷却液收集器的出口处设有第二单向阀；所述第二单向阀在所述冷却液收集器中冷却液上升到预定高度后自动开启，所述冷却液收集器中冷却液通过所述第二管道流入所述散热片，在所述冷却液收集器中冷却液下降到预定高度后自动关闭。
设置了第二单向阀之后，第一单向阀在散热片内汽化膨胀产生的推力作用下打开，第二管道内的液体经过降温之后进入冷却液收集器，在冷却液收集器内的第二单向阀处于关闭状态，冷却液收集器内的液体不断增多高度不断增加，在液体高度达到预定值时，第二单向阀自动打开，收集器中的液体通过第二管道流入散热片，当收集器内液体下降到预定高度后第二单向阀自动关闭，继续存储液体。
优先地，所述第二单向阀包括：浮标、支撑杆、连接杆和用于密封所述冷却液收集器出口的密封体；所述连接杆一端连接所述浮标、另一端与所述支撑杆一端活动连接，所述支撑杆的另一端固定在所述冷却液收集器上，所述浮标漂浮在所述冷却液收集器中，与所述密封体通过线段连接；
所述第二管道内液体流入所述冷却液收集器内，冷却液收集器内液体高度不断增涨，浮标也随着液体高度的增涨向上运动；当液体上升到一定高度之后，在液体浮力作用下所述浮标通过所述线段拉开所述密封体；液体下降到预定高度之后，在液体压作用下所述密封体密封所述冷却液收集器出口。
进一步为能够使得液体能够顺利流入散热片，本实施例散热装置，还可以在所述第一管道中或者所述散热片的进口处设有第三单向阀；
所述冷却液收集器中的冷却液流入所述所述第一管道后，在冷却液的推力作用下自动开启，冷却液流入所述散热片；在所述散热片内冷却液与所述单板进行热交换且汽化，之后在所述散热片内液体汽化膨胀作用下自动关闭。
具体地，为了液体能够顺利流入散热片，在散热片和液体收集器出口相连的管道内，设置一个单向阀，单向阀首先在液体推力作用（例如重力）下打开，液体缓缓流入散热片，散热片液体达到一定高度后，单向阀在液体压力和汽化膨胀气体作用下关闭，液体停止流入。
本实施例散热装置可以设置第一单向阀、第二单向阀和第三单向阀中的至少一个。
实施例三：
根据上述实施例一和二介绍的方案，本实施例提供了一种散热装置，如图3所示，由冷却液收集器1，散热片2，以及热涡流发生交换器3组成，散热片2安装在通讯设备的单板上、散热片2上下各设有一个进口21和出口22，进口21通过管道4和管道5与冷却液收集器1的出口11相连，出口22也通过管道6、7、8与涡流发生器的进水管道31相连，涡流发生器的出水管道34通过管道9和液体收集器进口12相连，达到一个闭环的循环系统，在流发生交换器3内壁上设有环形管道，进水管道31、环形管道两和出水管道34相邻依次相连。
如图4所示，在液体收集器的进口12，为了防止液体由于重力作用倒流，安装一个单向阀13，单向阀13在涡流发生器管道34和管道9内的液体推力作用下打开，以便液体流入液体收集器1，一旦液体收集完成，单向阀13由于液体的压力作用将进口12密封，从而达到阻止液体倒流。
如图4所示，为了液体能够顺利流入散热片2，在液体收集器1的出口11处设置一个单向阀14，该单向阀14包括：浮标141、支撑杆142、连接杆143和用于密封所述冷却液收集器出口11的密封体144；液体收集完成之后，单向阀14在浮标12浮力作用下打开，具体浮标141液体浮力作用下拉开所述密封体144，液体经过管道4和5流入散热片2；在液收集器1内的液体下降低到一定高度时，单向阀在液体压力作用下关闭，具体地，在液体压力作用下密封体144密封冷却液收集器出口11。
进一步为了液体能够顺利流入散热片2，在管道4或管道5中设置一个单向阀，或者也可以在散热片2的出口21处设置一个单向阀23，如图5所示；单向阀23首先在液体重力作用下打开，液体缓缓流入散热片2，散热片液体达到一定高度后，单向阀23在液体压力和汽化膨胀气体作用下关闭，液体停止流入。
散热片2的液体在进行热交换以后，在散热片内液体汽化膨胀作用下，经过管道6、7、8被排入涡流发生器入口31；如图6和7所示，涡流发生器3由于热力作用，由涡流发生器3底部的入口35吸入 冷气，五个入口35与涡流发生器底部的圆形构造相切，使气体沿涡流发生器内壁33极速环形上升，形成涡流，涡流在与镶嵌在内壁上的环形管道极速接触过程中，完成热交换过程，达到散热目的。
为了更好地促使涡流快速形成，涡流发生器3的内壁设计成椭圆形，出口32设计成翁形，气流沿进气口35相切进入内壁，沿内壁在热力作用下螺旋上升，五条进气道同一方向旋转，形成强力涡流极速上升。椭圆形的内壁，促使进口气流在外形作用下极速形成涡流，在出口收窄的情况下，有助于气流形成密集涡流，对气流起到极速拉升作用。
为了发挥涡流热交换的作用，涡流发生器由密集的环形管道镶嵌或相围成形，气流在极速螺线上升过程中与镶嵌在内壁上的环形管道高速接触，达到极速降温的目的。
为了有效让散热片2内已经过热的液体排出，且冷液体循环进入，利用汽化气体膨胀的原理，将管道6、7和8的内径大于涡流发生器进口31的内径5倍以上，这样可以防止气流混入液体无效排出，可以在气体压力下，有效排出液体。
为了是热液体尽速降温，将涡流发生器3内部的管道内径尽量设计小，而管道长度尽量长，形成涡流发生器体积尽量大，这样与涡流气流增大接触面，可以使液体在尽快冷却。
