Description

一种内燃机散热方法及装置 技术领域
本申请涉及散热领域, 具体是一种内燃机散热方法及装置。
 背景技术
自从人类发明制造了内燃机，内燃机因为其能够把化学能量转化成机械能量，传递给其他机构而实现非常多的应用，例如驱动汽车，食品加工机械，驱动工业机器，驱动火车飞机轮船等等，无处不在的内燃机使我们改变了世界，改变了生活，内燃机在使用过程中会有大约一半的能量以热能的方式浪费掉，这部分热能通过内燃机机体和排气释放，通过机体释放的热量会使内燃机超过内燃机本身过热而影响其工作的最佳状况，甚至损坏内燃机，因此需要采取方法帮助内燃机本体及时释放这部分热量，现有技术中最常见的是使用风冷和液冷的方法，风冷直接利用内燃机周围的风散热，经常因为内燃机周围的风不流动或流动不良而效率很低，散热不充分，或者用电扇加速散热，液冷是利用内燃机本体外层设置液体包，由导热的液体介质带走内燃机本体的热量到更大面积的散热片，同时利用电风扇将吹动散热器周围的空气加速流动而将内燃机本体的热量释放掉，但是这种方法具有需要增加电动装置并且额外消耗能量，需要转动部件，液体介质腐蚀管道容器等问题，因此常因为电力电器和转动部件损坏而影响内燃机的工作，甚至使内燃机完全损坏而停止工作，因此内燃机需要更经济更安全可靠地散热才能保证内燃机的正常运行，从而保证内燃机所驱动的其他装置正常工作，现有上述内燃机的散热技术方案存在上述问题，经常需要检查维护，因此需要设计改进。

 技术解决方案
本申请的目的是在于提供一种内燃机散热的方法及装置，具体是利用内燃机本身的排出气体所含有的热能和动能直接驱动内燃机附近的气体流动，实现内燃机利用内燃机浪费的能量而不需要额外消耗能量，没有转动部件，达到帮助内燃机散热的目的。 
本申请为实现上述目的，通过以下技术方案实现：一种内燃机散热方法，内燃机工作通过排气管排出气体，内燃机工作需要散热，以导流管道连接内燃机至所述排气管口附近，利用内燃机排出气体从所述导流管道口附近流过，带动所述导流管道内空气流动，从而使内燃机附近空气加速流动而给内燃机加速散热，本方法除了给内燃机本体加速散热，还可以用于给内燃机配套部件散热。
一种内燃机散热装置，包括导流管道，所述导流管道进气端开口靠近并半包裹内燃机，所述导流管道出气端开口与排气管道的开口形成内外涵道式套管，从内燃机排出气体从所述涵道式套管的其中一个涵道排出，带动所述涵道式套管连接导流管道的另一个涵道的空气加速流动，从而使内燃机附近空气加速流动而给内燃机加速散热。
所述内外涵道式套管的内管管口比较外管管口缩进，这样的结构有利于内外涵道流体在外管内发生相互作用。
所述内外涵道式套管的内管至少设有2个分管，设置多个分管可以是内外涵道的流体在多个位置相互作用，能够使相互作用更加均匀有效。
所述内外涵道式套管的内管与内燃机的排气管道连接，所述内外涵道式套管的外管与导流管道连接，这样设置使内燃机的排气通过内外涵道式套管的内涵道排出，而与内外涵道式套管的外涵道流体发生作用，带动外涵道的流体与内涵道的流体一个方向运动，当所述外管与导流管道连接，外涵道流体即空气产生流动，通过导流管道作用于内燃机附近空气加速流动，加速内燃机的散热。
在所述导流管道设有自动阀门，所述自动阀门 与内燃机的温度控制系统连接，在不需要给内燃机散热的时候，关闭导流管道，在需要给内燃机散热的时候，打开导流管道。
在所述导流管道进气端设有分导流管道，所述分导流管道连接内燃机的散热片和电路部件至少其中一个，并设有自动阀门以控制分导流管道的打开或关闭。
 有益效果
本申请的有益效果在于：采用本申请所述的一种内燃机散热的方法及装置，抛弃现有大多数内燃机的利用水泵驱动散热器内的介质流动，利用电子风扇吹散热器的散热方法，利用倒流管道和内燃机排气管道组合成涵道结构，利用内燃机本身工作的时候排除的气体所具有的热量和动能，达到给内燃机加速散热的目的，比较现有技术具有以下优点：第一是利用内燃机本身工作中浪费的排气资源，不用额外消耗电量燃料等；第二是本申请的方法和装置中不含有转动部件，不含有电子电动部件，只有管道间的流体之间的相互作用，不会因为转动，电子设备故障而损坏内燃机，因此可以长期免维护工作；第三是采用本申请的方法和装置减少了设备，节约成本；第四是比较现有内燃机散热方法，本申请的方法和装置还可以同时给其他部件散热；由此，采用本申请的方法和装置能够实现保障内燃及其散热系统的安全稳定运行。

 本发明的最佳实施方式
下面结合具体实施例，进一步阐述本申请，图1为本申请的一种内燃机散热装置示意图，图中1为内燃机，所属内燃机1具有排气管2,和内燃机进气管5，助燃气体通过内燃机进气管5进入内燃机，经过与燃料混合燃烧，对外做功，并且有废气从排气管2排出，内燃机1的其他配套不再在本附图中不再体现，排气管2的出口部分形成内管3，与外管4形成内外涵道式套管结构，内管3的nebula空间为内涵道，内管3和外管4之间的空间为外涵道，外管4延伸至内燃机1的外围，形成半包围的结构，称为导流罩6，内管3比较外管4缩进一定距离，当内燃机1进行工作的时候，排气管2排出废气，废气以一定的速度和具有一定的热量从内管3喷出，内涵道的气体流速快，根据伯努利原理，流速快的流体压力低，因此内涵道形成低压区域，外涵道气体从高压区域流向低压区域，因此废气的热量和动能传递给外涵道的气体，内外涵道的气体一起排出，因为外管4一直延伸至内燃机的附近，并且在内燃机1外围形成半包围结构，外涵道流动的气体将从导流罩6的缺口流入，加速经过内燃机1的外围，带走内燃机1的热量。
图2为本申请的一种具有分管的内燃机散热装置示意图； 本附图2是在附图1的基础上改进的结构，主要是在排气管2的口部设置分管7，图中显示的分管7为3个，实际应用中可以增加减少分管7的数量，设置分管7可以将排气管2排出的废气通过分管7的各个口喷出，使具有一定热量和速度的废气均匀分布在外管4的径向的空间内，使外涵道的气体能够与内涵道的气体迅速混合，传递热量的动能，提高效率，因而能够增加外涵道气体流速，即增加设置在内燃机1周围的导流罩6处进入气体的流速，提高对内燃机1的散热效率。
图3为本申请的图2具有分管的端面示意图；从外观4的端面上看，可以清晰其内部分管7的分布情况，在本附图中设有3个分管7,3个分管7均匀分布在外管4的径向内部空间里，外涵道进入的气体不仅流过分管7外侧，也流过分管7之间的空间，因而增加气体间相互交换热量和动能的位置，提高效率。
图4为本申请的一种排气管在外管的内燃机散热装置示意图；在本附图中，排气管2排出的废气经过外管4排出，而内管3延伸至内燃机1附近并在内燃机1外围形成半包围结构，外涵道流动的气体将从导流罩6的缺口流入，加速经过内燃机1的外围，带走内燃机1的热量，本附图4与附图1具有一样的原理，在此不再陈述，这样的设置方便不同应用实施例中，方便结构具体布置。
图5为本申请的图4具有分管的内燃机散热装置示意图；本附图5是附图4的改进，主要是设置分管7，增加外涵道气体流速，提高对内燃机1的散热效率，与附图2具有同样的原理。
图6为本申请的另一内燃机散热装置示意图；图中1为内燃机，2为排气管，4为外管，5为内燃机进气管，6为导流罩，7为分管，8为第一电磁阀，9为第二电磁阀，10为散热器，11为导流分管，12为进气孔在本附图中，设置第一电磁阀8和第二电磁阀9，分别控制各自管道的导通或关闭，适应内燃机1在不同工作状态下的情况，设置分导流管11延伸至内燃机1的散热片10附近，并半包围散热片10，散热片10通过其内部的散热介质连接内燃机内部，通过散热介质的循环带走内燃机1产生的热量，分导流管11可以利用上述相同的原理加速散热片10附近气体流动，加速散热片10的散热，在内燃机1启动阶段或环境温度很低的阶段，关闭电磁阀8和电磁阀9，减少内燃机1附近气体流通，有利于内燃机1温度的提升，档内燃机1温度达到设定温度，打开需要的电磁阀导通导流管内气体加速流动，加速内燃机1散热，设置进气孔12能够针对内燃机1的不同部位进行气体加速驱动，调节进入气体的部位，使该部位得到更好的散热。
外管靠近内燃机的一端可以设置多个进气孔，从内燃机的不同位置进气，以能够给予内燃机不同部位均衡散热。
本申请的一种内燃机散热方法及装置可以广泛应用于具有内燃机的汽车，工业，农业，国防等领域。
这里仅通过所选的实施例对本申请进行了说明，在实际应用中，所述发动机的排气，进气和辅助散热器分别与发动机的相关结构连接，发动机的排气，进气和辅助散热器与发动机的连接，并非直接连通，在本实施例的各个附图中，本申请附图只是用于说明其原理，因此显而易见的是，上述的实施例用于说明而不是用于限定本申请。
