具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
结合图2至图7所示，根据本申请的实施例，提供了一种换热器。
具体地，如图2所示，该换热器包括换热组件10、翅片20，翅片20位于相邻两个换热组件10之间，换热组件10具有供冷媒通过的第一通道11和第二通道12，以及连通第一通道11和第二通道12的连通部，第一通道11、第二通道12和连通部上设置有多个凸起40，且第一通道11、第二通道12上凸起的密度大于连通部上凸起的密度，第一通道11、第二通道12上凸起的尺寸大于等于连通部上凸起的尺寸。
在本实施例中，通过具有第一通道、第二通道及连通部的换热组件，实现冷媒在第一通道与第二通道内的导通，无需对换热组件进行折弯，即可形成双排换热器，相同换热量情况下，换热器的长度不会增加，安装空间不受限，同时也降低了制造成本。通过在连通部设置较大密度和较大尺寸的凸起，可保证连通部的耐压强度及冷媒流场均匀性。通过将第一通道与第二通道的横截面面积设置成不同的方式，降低了通道内冷媒的压降，以提高冷媒的散热或制冷效率，进而提高了换热器的换热效率。
如图3所示，换热组件10包括本体30，本体30具有容纳腔31，本体30长度方向的端部上开设有第一开口32和第二开口33；筋条36，筋条36设置于容纳腔31内，筋条36将容纳腔31隔离为相连通的第一腔体和第二腔体，第一腔体形成第一通道11并与第一开口32相连通，第二腔体形成第二通道12并与第二开口33相连通，第一开口32和第二开口33中的一个用于通入冷媒，另一个用于导出冷媒。这样设置便于通过筋条36将容纳腔31隔离为第一通道11和第二通道12，其中，第一通道11和第二通道12的横截面面积不同，当高压冷媒由窄的第一通道11流入宽的第二通道12变为低压冷媒时，因高压冷媒的外部通道由窄变宽，便于高压冷媒转变为低压冷媒，进而便于吸收热量，或者，当低压冷媒由宽的第二通道12流入窄的第一通道11时，因低压冷媒的外部通道由宽变窄，便于低压冷媒转变为高压冷媒，进而便于散发热量。
如图4和图6所示，本体30包括第一板34和第二板35，第一板34和第二板35相连接并围设形成容纳腔31，第一板34和第二板35朝向容纳腔31的一侧各设置有筋条36，通过两个筋条36相互抵接，进而将壳体内隔离为第一通道11和第二通道12，当然，也可以只在 第一板34或第二板35朝向容纳腔31的一侧设置筋条36，以将壳体内隔离为第一通道11和第二通道12。
在本实施例中，第一板34或第二板35在靠近连通部的端部具有翅片阻挡部，当然，也可以在两者都设置翅片阻挡部，翅片阻挡部由本体30在端部弯折形成。翅片阻挡部用于固定和安装翅片，且提高了换热器的组装效率。
在本实施例中，第一开口32和第二开口33可为贯通本体30的孔，以便于第一开口32和第二开口33中的一个用于通入冷媒，另一个用于导出冷媒。此外，多个本体上的开口叠加可形成集流腔，从而无需另设集流管。
如图3至图5所示，连通部上的凸起40的为条形凸起，且条形凸起与换热组件10的长度方向具有夹角。这样设置便于能有效的对冷媒进行导流，便于冷媒由第一通道导入第二通道或由第二通道导入第一通道，且根据需要控制第一通道11和第二通道12内冷媒的压力，进而提高换热组件的换热效率。
如图3所示，条形凸起呈弧形。这样设置便于能有效的对冷媒进行导流，且根据需要控制第一通道11和第二通道12内冷媒的压力，进而提高换热组件的换热效率。
在本实施例中，第一通道11的横截面面积与第二通道12的横截面面积不同。这样设置提高了第一通道和第二通道中导通的冷媒在高低压状态之间的转换效率，以提高冷媒的散热或制冷效率，进而提高了换热器的换热效率。
如图3所示，第一通道11的横截面面积为S1，第二通道12的横截面面积为S2，S1：S2＝a，a∈[0.5～1]。最佳比例S1:S2＝2：3。这样设置降低了通道的冷媒压降，增加冷媒的质量流量，进而提高了换热器的换热量和能效。
进一步地，在其它实施例中，换热器还包括第一集流管、第二集流管、进液管60和出气管50，第一集流管与多个换热组件10的第一通道11分别连通，第二集流管与多个换热组件10的第二通道12分别连通，与第一集流管连通，与第二集流管连通；其中，进液管60的管径小于出气管50的管径，或第一集流管的管径小于第二集流管，当然，两者也可以同时存在，这样设置降低了集流管或进液管60内腔容积和重量，减少了换热器的制冷剂充注量和材料成本。
上述实施例的换热器还可以用于空调设备技术领域，即根据本申请的另一方面，提供了一种空调器，该空调器包括换热器，换热器为上述实施例中的换热器。
如图6和图7所示，凸起40的横截面为类三角形结构，位于第一通道11内的凸起40的一个角朝向第一开口32设置，或位于第二通道12内的凸起40的一个角朝向第一开口32地设置。当然，两者也可以同时存在，类三角形结构可以为直角三角形结构，也可以为角部为圆弧的三角形结构，这样设置便于能有效的对冷媒进行导流，且根据需要控制第一通道11和第二通道12内冷媒的压力，进而提高换热组件的换热效率。
如图2所示，换热组件10为多个，多个换热组件10相间隔地设置，换热器还包括：翅片20，翅片20位于相邻两个换热组件10之间，翅片20为波浪形，翅片20的宽度与本体30的宽度相同。这样设置便于冷媒将热量充分传递到翅片上，进而与外界进行换热。
如图1所示，现有技术中，常规微通道换热器的芯体主要采用微通道扁管10’、翅片、边板、出气管50’、进液管60’制造。常规微通道换热器的集流管直径比微通道扁管的宽度要大。常规双排折弯的微通道换热器的折弯区域需预留一段无翅片的芯体部分，且折弯后会有4mm至7mm间隙。由于常规微通道换热器的集流管直径比微通道扁管的宽度要大，集流管内腔容积和重量都比较大，导致换热器的制冷剂充注量和材料成本较大，由于折弯区域预留一段无翅片的芯体部分，为保证相同的换热量，需加长换热器的长度，导致换热器的制冷剂充注量和材料成本较大；由于折弯区域预留一段无翅片的芯体部分，翅片数量需要增加一倍，导致换热器的装配需要更多时间，增加了换热器的制造成本；微通道扁管10’包括第一微通道扁管11’和第二微通道扁管12’，由于折弯后第一微通道扁管11’和第二微通道扁管12’有4mm至7mm间隙，导致换热器的安装空间宽度增加，使该种换热器的使用受限。
本申请中，换热器的集流管直径可以做得更小，降低了集流管内腔容积和重量，减少了换热器的制冷剂充注量和材料成本，或者也可通过设有开口的本体叠加形成集流腔来取代集流管；换热组件不需要折弯区域，不需加长换热器的长度，减少了换热器的制冷剂充注量和材料成本；本申请的产品结构在装配过程和现有的没有变化，不但不增加额外工序，还会降低常规双排折弯的微通道换热器的由于翅片增加导致的装配工序，减少了换热器的制造成本。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
