具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述根据本发明实施例的换热器1。本领域的技术人员需要理解地是，下述上下方向均与换热器1正常使用时的上下方向为准。
如图1-图9所示，根据本发明实施例的换热器1包括第一集流管10、第二集流管20、扁管30、翅片40、接口管和翅片40。
第一集流管10和第二集流管20竖直且间隔开设置。扁管30水平设置，且扁管30的两端分别与第一集流管10和第二集流管20相连。翅片40为波纹翅片且设在相邻扁管30之间。所述接口管焊接在第一集流管10和第二集流管20中的至少一个集流管上。导水件60设在所述接口管和/或所述至少一个集流管上。换言之，导水件60可以设在接口管上，导水件60也可以设在与接口管焊接的集流管上，导水件60还可以设在接口管和与接口管焊接的集流管上。
其中，接口管包括进口管51和出口管52，进口管51和出口管52可以同时设置在第一集流管10和第二集流管20中的一个上(如图3、图5、图8和图9所示)，也可以分别设置在第一集流管10和第二集流管20上(如图1、图2、图4、图6和图7所示)。
根据本发明实施例的换热器1，通过在接口管和/或与接口管焊接的集流管上设置导水件60，可以利用导水件60将换热器1表面特定部分的积水引流到换热器1外，防止水在换热器1表面堆积或流过，例如，可以防止水堆积在接口管与集流管的焊接处，尤其换热器1作为蒸发器或应用于热泵时，可以防止雨水积流过换热器1的暴露在空气中的薄弱区域，从而避免雨水中夹带的金属离子或其它活泼介质腐蚀换热器1表面，大幅降低了换热器1被腐蚀的风险，进而提高换热器1的使用寿命。因此，根据本发明实施例的换热器1能够有效防止因表面积水而被腐蚀，具有使用寿命长等优点。
下面参考附图描述根据本发明具体实施例的换热器1。
在本发明的一些具体实施例中，如图1-图9所示，根据本发明实施例的换热器1包括 第一集流管10、第二集流管20、扁管30、翅片40、接口管和翅片40。
进一步地，导水件60邻近所述接口管与所述至少一个集流管相焊接的焊接位置设置，换热器1表面的水在流到接口管与集流管的焊接处之前会被导水件60排出换热器1外，从而更好地防止水堆积在接口管和集流管的焊接处。
在本发明的一些具体示例中，如图1-图3所示，导水件60设在所述接口管上，导水件60可以防止接口管上的水沿接口管的外壁流至接口管与集流管的焊接处。
可选地，如图1所示，导水件60为套设在所述接口管上的导水盘，导水盘为开口背向与接口管焊接的集流管的圆形或椭圆形盘状，导水盘的外周沿设有向外延伸的一圈凸起，导水盘收集沿接口管流淌的水，并引导收集的水在重力作用下排出，以防止接口管上的水流淌至接口管与集流管的焊接处。此外，导水盘的设置不会对换热流道产生影响，不增加风阻，从而避免了对换热性能的影响。
有利地，如图1所示，导水盘(即导水件60)可以由橡胶或其它柔软且防腐蚀的材料制成，导水盘具有沿导水盘的径向延伸且切割导水盘的切口61，导水盘可以直接穿过接口管以套设在接口管上，也可以通过切口61卡装在接口管上，由此可以方便导水盘的安装，且可以使导水盘的安装方式更加灵活，适用于不同管径大小的接口管。
进一步地，如图1所示，导水盘(即导水件60)的下沿设有从导水盘向下延伸的引水条62，引水条62可以引导导水盘上的水下流排出换热器1，进一步防止接口管上的水流淌至接口管与集流管的焊接处。
在本发明的一些具体实施例中，如图2所示，导水件60为挡水块，挡水块的上表面上设有与接口管适配的凹槽，在接口管的横截面上，接口管的至少下半部分配合在所述凹槽内，即挡水块至少与接口管的下半部壁贴合，接口管上的水流淌至挡水块处后会被挡水块止挡，而无法继续流至接口管与集流管的焊接处。
具体而言，如图2所示，与接口管焊接的集流管上设有支架63，支架63可以通过抱箍、扎带或弹簧等方式紧固在集流管上，支架63上设有弹性件64，挡水块(即导水件60)为柔性块且设在弹性件64上。其中，弹性件64可以保证挡水块与接口管紧密贴合，支架63用于支撑弹性件64和挡水块。本领域的技术人员可以理解地是，支架63可同时用作换热器1的安装支架，以方便换热器1与机组安装。
在本发明的一些具体示例中，如图1和图2所示，进口管51和出口管52可以分别焊接在第一集流管10和第二集流管20上，换热介质从进口管51进入与第一集流管10，然后通过扁管30流入第二集流管20，最后由出口管52流出。进口管51和出口管52中的至少一个上设有邻近对应集流管的导水件60。
如图3所示，进口管51和出口管52也可以同时焊接在第一集流管10和第二集流管20 中的一个上，第一集流管10和第二集流管20内分别设有挡板，冷却介质由进口管51进入后，通过扁管30在挡板的引导下在第一集流管10和第二集流管20之间蛇形流动，最后由出口管52流出。进口管51和出口管52中的至少一个上设有邻近对应集流管的导水件60。
在本发明的一些具体实施例中，如图4和图5所示，导水件60设在与接口管焊接的集流管上，且导水件60位于接口管与集流管相焊接的焊接位置上方，导水件60可以防止集流管上的水沿集流管的外壁流至接口管与集流管的焊接处。
可选地，如图4和图5所示，导水件60为套设在集流管上的导水盘，导水盘为开口朝上的圆形或椭圆形盘状，导水盘的外周沿设有向外延伸的一圈凸起，导水盘收集沿集流管流淌的水，以防止集流管上的水流淌至接口管与集流管的焊接处。此外，导水盘的设置不会对换热流道产生影响，不增加风阻，从而避免了对换热性能的影响。
有利地，如图4和图5所示，导水盘(即导水件60)可以由橡胶或其它柔软且防腐蚀的材料制成，导水盘具有沿导水盘的径向延伸且切割导水盘的切口61，导水盘可以直接穿过集流管以套设在集流管上，也可以通过切口61卡装在集流管上，由此可以方便导水盘的安装，且可以使导水盘的安装方式更加灵活，适用于不同管径大小的集流管。
进一步地，如图4所示，导水盘(即导水件60)的边缘设有排水嘴65，导水盘上设有从排水嘴65向下延伸的引水条62，导水盘收集的水满后，从排水嘴65溢出并沿引水条62下流，从换热器1排出。
在本发明的一些具体示例中，如图4所示，进口管51和出口管52可以分别连接在第一集流管10和第二集流管20上，换热介质从进口管51进入与第一集流管10，然后通过扁管30流入第二集流管20，最后由出口管52流出。第一集流管10和第二集流管20中的至少一个上设有导水件60。
如图5所示，进口管51和出口管52也可以同时焊接在第一集流管10和第二集流管20中的一个集流管上，第一集流管10和第二集流管20内分别设有挡板，冷却介质由进口管51进入后，通过扁管30在挡板的引导下在第一集流管10和第二集流管20之间蛇形流动，最后由出口管52流出。在与进口管51和出口管52焊接的集流管上，进口管51与集流管的焊接位置以及出口管52与集流管的焊接位置中的至少一个焊接位置上面设有所述导水件60。换言之，与进口管51和出口管52焊接的集流管上设有至少一个导水件60，导水件60位于对应焊接位置的上方。
在本发明的一些具体实施例中，如图6和图7所示，进口管51焊接在第一集流管10上，出口管52焊接在第二集流管20上，换热介质从进口管51进入与第一集流管10，然后通过扁管30流入第二集流管20，最后由出口管52流出。进口管51、出口管52、第一集流管10和第二集流管20上分别设有导水件60。由此可以防止进口管51、出口管52、 第一集流管10和第二集流管20上的水流淌至进口管51与第一集流管10的焊接处以及出口管52与第二集流管20的焊接处，从而降低进口管51与第一集流管10的焊接处以及出口管52与第二集流管20的焊接处被腐蚀的风险，提高换热器1的使用寿命。
可选地，如图6和图7所示，导水件60为圆形或椭圆形盘状的导水盘，导水盘的外周沿设有向外延伸的一圈凸起，导水盘可以由橡胶或其它柔软且防腐蚀的材料制成，导水盘具有中心安装孔，用于导水盘与对应管件的套装，且导水盘上进一步设有与中心安装孔连通且沿导水盘径向延伸的切口61，切口61可以进一步方便导水盘的安装。
进一步地，如图7所示，第一集流管10上的导水件60与进口管51上的导水件60通过引水板66彼此相连，第二集流管20上的导水件60与出口管52上的导水件60通过引水板66彼此相连，引水板66为朝上且朝向远离焊接位置凸出的弧形板。由此可以利用两个引水板66和四个导水件60将进口管51与第一集流管10的焊接处以及出口管52与第二集流管20的焊接处与外界环境隔离，进一步防止水积留或流经进口管51与第一集流管10的焊接处以及出口管52与第二集流管20的焊接处。
在本发明的一些具体实施例中，如图8和图9所示，进口管51和出口管52均焊接在第一集流管10上，第一集流管10和第二集流管20内分别设有挡板，冷却介质由进口管51进入第一集流管10后，通过扁管30在挡板的引导下在第一集流管10和第二集流管20之间蛇形流动，最后流回第一集流管10并由出口管52流出。进口管51、出口管52和第一集流管10上分别设有导水件60。本领域的技术人员需要理解地是，第一集流管10可以设有一个导水件60，该导水件60位于进口管51和出口管52中位置较高的一个的上方。第一集流管10上也可以设有两个导水件60，两个导水件60分别位于进口管51和出口管52的上方。由此可以防止进口管51、出口管52和第一集流管10上的水流淌至进口管51和出口管52与第一集流管10的焊接处，从而降低进口管51和出口管52与第一集流管10的焊接处被腐蚀的风险，提高换热器1的使用寿命。
可选地，如图8和图9所示，导水件60为圆形或椭圆形盘状的导水盘，导水盘的外周沿设有向外延伸的一圈凸起，导水盘可以由橡胶或其它柔软且防腐蚀的材料制成，导水盘具有中心安装孔，用于导水盘与对应管件的套装，且导水盘上进一步设有与中心安装孔连通且沿导水盘径向延伸的切口61，切口61可以进一步方便导水盘的安装。
进一步地，如图9所示，第一集流管10上设有两个导水件60，两个导水件60分别位于进口管51和出口管52的上方，第一集流管10上的两个导水件60与进口管51和出口管52上的导水件60分别通过引水板66彼此相连，引水板66为朝上且朝向远离焊接位置凸出的弧形板。由此可以利用两个引水板66和四个导水件60将进口管51和出口管52与第一集流管10的焊接处与外界环境隔离，进一步防止水积留或流经进口管51和出口管52与 第一集流管10的焊接处。
