具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
实施例一：
实施例一提供的是一种瓦楞筒消声换热结构。如图1和2所示，包括瓦楞筒1、金属筒Ⅰ2、第一工质入口3和第一工质出口4，瓦楞筒1是由折叠成瓦楞状的金属带弯曲围成的筒状体，且瓦楞槽的延伸方向与筒状体的轴向一致，金属筒Ⅰ2置于瓦楞筒1的筒腔内，其外壁紧靠瓦楞筒1内壁的内齿峰，使内侧的瓦楞槽形成一个个单独的两端开口的内瓦楞槽通道，瓦楞筒1于前、后端分别通过封堵13封闭，封堵13可采用板材实现瓦楞筒1前、后端的封闭。金属筒Ⅰ2内设置隔板5，隔板5将封闭的瓦楞筒1内的空间分割为前室6和后室7，第一工质入口3和第一工质出口4设在瓦楞筒1的同一端或分别设在不同端，第一工质入口3和第一工质出口4分别与前室6和后室7连通，使第一工质入口3、前室6、内瓦楞槽通道、后室7及第一工质出口4构成依次连通的第一工质的消声通路；当第一工质入口3和第一工质出口4设在同一端时，是通过管道穿过其中的一个室连接在隔板5上且与另一个室相连通。
如图3所示，瓦楞筒1近中心轴的折弯处为内齿峰，远离中心轴的折弯处为外齿峰；瓦楞筒1的内齿峰与金属筒Ⅰ2的外壁焊接形成内瓦楞槽通道，瓦楞筒1的外齿峰通过与另一相围的金属筒Ⅱ20的内壁焊接形成外瓦楞槽通道，瓦楞筒1的内瓦楞槽通道和外瓦楞槽通道相互叠嵌；瓦楞筒1的瓦楞槽通道两端口可由密封翅带封堵，使两端的内、外瓦楞槽通道口相互独立，被密封翅带封堵的瓦楞槽通道口开在侧面；每个瓦楞槽通道轴截面为矩形或抛物线形状，瓦楞槽通道的轴向壁面为平直式或曲折式或交叉波纹式等，交叉波纹式壁面仅适合抛物线形瓦楞槽通道；瓦楞筒1的前室6和后室7依需要可另设共振腔，还可在瓦楞筒1内及隔板5上设置其它消声元件以构成多种排气消声结构。
本发明的实施例中，在后室7内设一延伸管12，该延伸管12一端沿径向向外延展与瓦楞筒1内口缘连接，另一端沿轴向向远离第一工质出口4的方向延伸，延伸管12与金属筒Ⅰ2之间隔一定距离形成与内瓦楞槽通道连通的气流通道。延伸管12的单独作用是导流并将气流和噪声分离；延伸管12可与其内另外设置的管道之间隔一定距离形成一个平抑脉动波作用的夹套管并与第二工质入口8连通，或使夹套管独立并由管道引出被利用，还可以 使夹套管成为一个独立的微穿孔共振吸声结构；封闭的瓦楞筒1内的空间包括瓦楞筒1的端部。
本发明提供的瓦楞筒消声换热结构为发动机的排气消声器时的降温降噪过程为：做完功的排气经由第一工质入口3、前室6、内瓦楞槽通道、后室7及第一工质出口4时，由于通道截面突然改变和前、后室的膨胀并来回反射，不但改变气流的方向而且也使气流在扩张和收缩的断面流动，排气噪声得到削减；同时，再利用瓦楞筒通道入口的尖劈分割、内瓦楞槽通道的气流分割、各微束噪声气流在大壁面通道中的折射反射和碰撞壁面耗损能量的综合作用下，排气能量最终以热能量形式向瓦楞槽通道壁面散出进而又传向大气，最后排气温度、声压及声强均快速降低而形成消声效果，并从第一工质出口4排出。
实施例二：
实施例二提供的是一种瓦楞筒消声换热结构。如图3所示，在实施例一的基础上，瓦楞筒1外套有金属筒Ⅱ20且设有第二工质入口8和第二工质出口9，该金属筒Ⅱ20的内壁紧靠瓦楞筒1的外齿峰，使外侧的瓦楞槽形成一个个单独的两端开口的外瓦楞槽通道，并且外瓦楞槽通道与内瓦楞槽通道之间构成相互叠嵌的瓦楞筒降噪传热的消声换热结构，各外瓦楞槽通道的两端开口分别汇集并分别与第二工质入口8和第二工质出口9连通构成瓦楞筒1的第二工质的消声换热通路。
实施例二是在实施例一基础上增加了一个金属筒Ⅱ20而形成外瓦楞槽通道，内、外瓦楞槽通道的端部依据结构需要可通过冲压折叠的金属带密封隔离。当内、外瓦楞槽的工质的相态及压力参数等不同时，应在低压力侧及低换热系数侧的瓦楞槽通道中增大通道截面积并加装翅片，以平衡体积流量、减少流阻、增大机械强度、强化该侧传热能力。本实施例可用于发动机排气消声并回收余热，如内燃机余热甲醇催化成合成气等；当第一工质出、入口设在同一端时，本实施例可用于热风、热水或采暖装置等；当第一工质出、入口设在同一端并且另一端再设置独立被加热的圆弧底锅时，本实施例将用于燃气灶具；此外，瓦楞筒1还可以与径流式叶轮机或压缩机等构成不同功能的热声装置，双瓦楞筒还可以构成多个消声换热通路。

进一步地，外环内瓦楞槽通道和外环外瓦楞槽通道可设置翅片。
本发明的实施例中，瓦楞筒消声换热结构的瓦楞筒1内的隔板5有前后两层，两层隔板5间设有空滤机电室11，空滤机电室11的入口端通过管道穿过后侧的隔板5和后室7与第一工质入口3连通，位于前侧的隔板5上设有开口，第一工质入口3、空滤机电室11、前室6、瓦楞筒1的内瓦楞槽通道、后室7、第一工质出口4、外环内瓦楞槽通道及第一工质总出口25构成第一工质的消声换热通路。
本发明的实施例中，压缩机15设置于空滤机电室11内的靠近第一工质入口3处，压缩机15的入口通过管路与瓦楞筒消声换热结构的第二工质出口9连通，压缩机15的出口通过管路与后端外环腔27连通；前端外环腔26通过节流阀16与第二工质入口8连通，第二工质入口8、瓦楞筒1的外瓦楞槽通道、第二工质出口9、压缩机15、后端外环腔27、外环外瓦楞槽通道、前端外环腔26及节流阀16依次连通构成闭式的第二工质的消声换热通路，形成由压缩机15驱动的降温冷凝循环系统。
进一步地，后室7的前部与瓦楞筒1的内瓦楞槽通道和第一工质出口4连通，第一工质出口4与外环内瓦楞槽通道连通。后室7的后部为集水槽，集水槽与出水口17连通。
进一步地，热声设备还包括送风装置，送风装置设置于空滤机电室11内并且安装在位于前侧的隔板5上的开口处。
如图4所示，本发明的实施例中，送风装置包括压气轮23和电动机24，压气轮23设置于位于前侧的隔板5的开口处，隔板5的开口形状与压气轮23的外形相适应并且形成间隙配合，气流经过压气轮23的叶片间隙进入前室6内。电动机24设置于空滤机电室11内，并且输出端与压气轮23连接，用于驱动压气轮23旋转。
进一步地，空滤机电室11内设有滤芯14，滤芯14位于电动机24和压缩机15之间，用于第一工质的净化。
进一步地，外环瓦楞筒18和瓦楞筒消声换热结构的瓦楞筒1之间隔一定距离形成一个环形空间10，构成夹套，该夹套承压性能好，可作为第三工质换热通道。
本实施例三是采用冷却结露式空气制水技术结构的热声设备，通过第二工质的制冷剂循环，使来至第一工质入口3的湿空气的温度在瓦楞筒1的内瓦楞槽通道中被冷却，温度降至饱和温度以下使空气中的水蒸气结露凝结成水，其在重力和空气流作用下流至底部集水槽并从出水口17流出；分离出水蒸气的空气进入外环瓦楞筒18的外环内瓦楞槽通道内，并且被制冷剂加热后从第一工质总出口25流出，以此实现空气制水。压缩机、电动机和空滤装置设置在瓦楞筒1内的目的是使装置整体结构紧凑，机械装置的噪声被瓦楞筒隔离吸收、热量被工质带出。
本发明采用双瓦楞筒消声换热结构构成的热声设备，是利用瓦楞筒的集成功能和瓦楞槽通道优良的热声特性，采用冷却结露式原理进行空气制水，该设备结构紧凑度和机械强度高，其体积和重量均小于同容量设备。
以上所述仅为本发明的实施方式，并非用于限定本发明的保护范围。凡在本发明的精 神和原则之内所作的任何修改、等同替换、改进、扩展等，均包含在本发明的保护范围内。
