Description

一种增湿组件 技术领域
本申请涉及增湿组件技术领域，尤其是涉及一种增湿组件。
背景技术
在现有的燃料电池系统中，通常需要设置增湿组件来确保电堆内部的空气能够维持在一定的湿度范围内，从而增强燃料电池系统的稳定性及性能表现。目前燃料电池系统传统的增湿组件及系统增湿方案常采用质子交换膜来实现加湿处理，具体原理是将经过电堆出来的带有湿气空气通入到增湿组件，利用质子交换膜将通入的湿气进行吸收、存储，并将其传递到即将进入到电堆内的干燥的空气中，从而实现对进入电堆的空气进行加湿的效果。
目前常用到的质子交换膜包括中空纤维膜管以及平板膜两种。其中，利用中空纤维膜管进行增湿，其制造工艺较为复杂且技术要求高，导致产品造价成本贵,批量生产困难，同时较为复杂的结构也导致体积偏大；而采用平板膜作为质子交换膜，为了确保水分的传递效果，通常需要对平板膜进行多层堆叠，将多个平板膜进行堆叠后其主要的缺点在于水分流阻较大，导致各个部分的平板膜的水分传递不均匀，影响增湿效果，同时，多层堆叠也一定程度增加了增湿组件整体体积。
因此，上述问题不仅导致现有的增湿组件其制造成本较高，且无论是应用了中空纤维膜管还是平板膜，因材料的水分传递效率难以提高，导致在确保其增湿性能的前提下产品体积难以实现小型化。

具体实施方式
为了便于理解本申请，下面将结合附图和具体的实施例对本申请进行更全面的描述。附图中给出了本申请的较佳实施方式。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本申请的公开内容理解的更加透彻全面。
请参考图1，图中示出了一种增湿组件的爆炸结构。
如图1所示，该增湿组件包括支撑组件1以及折叠膜2，该支撑组件1包括框体结构11以及设置于框体结构11相对两侧的第一盖体12与第二盖体13。该第一盖体12包括湿进口131及湿出口132，该第二盖体13包括干进口121与干出口122，该框体结构11中部形成容置腔。
该支撑组件1用于形成框体或壳体结构，可采用金属材料、高分子材料等常用于壳体的材料进行制造。该框体结构11、第一盖体12及第二盖体13的形态可以根据实际情况而定，例如该框体可以采用铝制框体，该铝制框体可以包括一体成型的四个侧板构成框架，从而在该框架中部围设成一个可以用于放置折叠膜2的容置腔。该框体还可以是两个或以上的结构共同构成框体结构11，从而适应不同的安装需求。同样的，该第一盖体12与第二盖体13的形态可以有多种，本申请对该框体结构11、第一盖体12及第二盖体13的具体结构形态不 做限定。
在一实施例中，该框体结构11可以采用四周包含侧板的铝框，该铝框与第一盖体12、第二盖体13之间可以设置有密封圈4进行密封，除此之外，铝框与第一盖体12、第二盖体13之间还可以采用注胶或者胶纸的方式确保两者之间的密封性能。
在另一实施例中，该框体结构11在与第一盖体12、第二盖体13连接处的两侧周缘延伸出限位边条111，该折叠膜2设置于两侧的限位边条111内。该限位边条111使得折叠膜2与框体结构11之间获得相对定位，从而固定折叠膜2在该增湿组件内部的位置，提高产品可靠性。
更具体的，该第一盖体12、第二盖体13之间可以通过在上面设置用于螺丝穿过的安装孔5，通过螺丝来对第一盖体12与第二盖体13之间进行固定。该安装孔5可以在第一盖体12与第二盖体13的周缘间隔设置，从而确保第一盖体12、第二盖体13与框体结构11内部形成相对密闭的空间。当然，除了安装孔5以外，可以通过设置卡扣、胶粘等方式实现第一盖体12与第二盖体13之间的安装，可以理解的，应用过程中第一盖体12与第二盖体13之间可根据实际情况设置本领域常见的安装方式。
请结合图2，图中示出了本申请实施例提供的增湿组件的剖面结构。如图2所示，该折叠膜2设于容置腔内，且具有多个连续的折叠结构21。折叠膜2与第一盖体12之间形成第一腔室，折叠膜2与第二盖体13之间形成第二腔室；第一腔体123与第二腔体133之间经折叠膜2相对隔离。具体的，该第一腔室与第二腔室之间可以利用折叠膜2进行隔离形成相对独立的空间，从而确保两个腔室之间的空气相对隔离。
部分传统的增湿组件采用了多层平板膜，将平板膜上下堆叠形成一个厚度较大的膜结构，利用多层平板膜的储水及水分传递效果来实现对一侧干燥空气的增湿。在本申请的一实施例中，盖折叠膜2采用了平板膜作为折叠膜2的材料，该平板膜可以是采用PVDF(聚偏氟乙烯)及PET无纺布构成的亲水膜，可以将空气中的水分进行捕获及存储。当然还可以采用其他亲水材料构成的膜材来制作折叠膜2。具体的，该折叠膜2通过对平板膜进行折叠，形成具有连续的、多个折叠结构21的折叠膜2。折叠结构21可以是对膜进行弯折形成的结构，通过多个连续的折叠结构21可以使得折叠膜2在同样的长度或宽度下具有与空气更大的接触面积，不仅单层膜的水分传递效果更好，不会产生传统多层堆叠平板膜出现的水分不均匀的问题，也因此提高了相同体积下的水分传递效率。同时，折叠膜2的制造方式相对简单，材料也更加便宜可靠，能有效降低产品的制造成本。除此之外，该折叠结构21也可以是多 个平板膜折叠后拼接而成，或者是采用同一块平板膜进行制作，具体的制作方式可根据实际情况而定。
为了获得更好的水分传递效率，该折叠结构21包括弯折部分，该折叠膜2折叠后形成的宽度大于相邻两个弯折部分之间的宽度。例如，图2中的折叠膜2在折叠后的宽度为d1，两个折叠结构21之间的d2，此时d1设置成大于d2，通过上述方式不仅可以提高单位体积下的折叠膜2与空气接触的接触面积，还可以适当降低空气在折叠结构21之间空隙中流动的流速，从而进一步提高水分传递效率。更具体的，该d1与d2的比值可以是大于1或者是5:1、10：1甚至达到20:1或以上比例。当然，该比值可以根据实际的应用需求而定，只要能确保空气能在不同折叠结构21之间进行流动即可。另外，该折叠结构21的折弯部分横截面可以呈V形或U形，具体的形态不限。
该第一盖体12和/或第二盖体13上设有用于减缓腔内空气流速的缓流结构3，该缓流结构3与折叠膜2相对。具体的，该第一盖体12以及第二盖体13，或者第一盖体12与第二盖体13的其中一个可以通过设置缓流结构3，使得外部流入到第一盖体12、第二盖体13内的空气能够在内部降低其流速，提高空气与折叠膜2表面的接触充分度，从而提高单位面积下的水分传递效率。
在一个实施例中，缓流结构3包括缓流脊，该缓流脊设置于第一盖体12的湿进口131与湿出口132之间，和/或设置于第二盖体13的干进口121与干出口122之间；该缓流脊与折叠膜2之间的距离，小于缓流脊两侧的第一盖体12或者第二盖体13与折叠膜2之间的距离。该缓流脊不仅可以通过将折叠膜2与盖体之间的距离减小，使得空气在缓流脊与折叠膜2之间减速，从而降低第一盖体12或第二盖体13的入口与出口之间的空气流速，并且能够引导部分空气流入到折叠结构21之间的间隙内，从而使得该部分空气能够更充分地与折叠膜2的表面进行接触，提高增湿效果。可以理解的，该增湿组件中的缓流脊可以设置一个或两个以上，可以是在盖体内部设置的脊状结构，也可以通过改变盖体的外形来形成该脊状结构，具体的形态方式不限。
该增湿组件具体的工作过程中，该支撑组件1用于支撑折叠膜2并形成该增湿组件的壳体，使得用于从电堆出来的带有水汽的空气通入到第一盖体12内，通过将水汽传递给到设置在容置腔内部的折叠膜2的一侧，利用折叠膜2的亲水特性将水分进行存储。与此同时，将用于进入到电堆的干燥空气通入到第二盖体13内，使得干燥空气流经存储有水分的折叠 膜2的一侧，从而对该干燥空气进行增湿后排出。上述过程利用到电堆出来的水汽对干燥空气进行增湿，无需额外的能源驱动，能够降低设备的能耗。
具体的，请参阅图3，图中示出了本申请实施例提供的增湿组件的内部风道结构。结合图3，在本实施例中，图中包括缓流结构3、第一腔体123及折叠膜2。其中该缓流结构3可以为缓流脊，气流(对应箭头)从图中的右侧往左侧流动，当部分气流流动到缓流脊后，受到缓流脊的阻挡后气流流动速率降低，并从第一腔体123内的该侧流动至缓流脊的另一侧，而部分气流经缓流脊的阻隔会改变流动方向，从而受缓流脊的结构表面引导而流向折叠膜2的相邻折叠结构21之间的空隙处，此时气流可以受到缓流脊的影响而更多地进入到折叠膜2的空隙中，从而与折叠膜2之间实现水分传递。
若没有设置缓流结构3，虽然折叠膜2提高了接触面积，但折叠膜2内的空隙因空间较小造成空气流速较慢，容易影响整体空气的增湿效率。通过缓流结构3与折叠膜2之间的配合，能够提高空气在折叠膜2内空隙的流速，相对于没有设置缓流结构3的方式可以提高空气与折叠膜2之间的水分传递效率。
另外，该干进口121与干出口122所形成的风道方向，与湿进口131与湿出口132所形成的风道方向可以是同向或者是反向，具体可以根据增湿组件所需的安装方式或其他条件而定，本申请对此不做限定。
本申请的增湿组件可以应用于具有燃料电池的电池组件中，为流入及流出该燃料电池的电池组件的空气提供湿度调节功能，确保该燃料电池的工作可靠性及工作效率。除此之外，该增湿组件也可以应用于其他需要增湿的产品中。
由上可知，本申请提供的增湿组件，在利用折叠膜的结构特性增加增湿组件内部空气与折叠膜之间的接触面积的基础上，通过缓流结构将空气引入折叠膜的结构空隙，并对流经折叠膜的空气进行流速减缓来增加接触时间，使得空气与折叠膜的接触更加充分，有效提高增湿组件内部空气与折叠膜之间的水分传递效率，从而在确保相同增湿性能下能够有效减小增湿组件的体积。
请参阅图4，图中示出了本申请实施例提供的增湿组件的另一爆炸结构。如图4所示，该增湿组件包括支撑组件1以及折叠膜，与图1的不同点在于，该支撑组件1包括用于对所述折叠膜进行限位的第一限位结构112及第二限位结构113。该第一限位结构112设于折叠膜与第一盖体12之间，该第二限位结构113设于折叠膜与第二盖体13之间。其中，第一限位结构112与第二限位结构113，用于限制折叠膜的位置，避免折叠膜因物理撞击导致失效。
其中，该第一限位结构112与第二限位结构113之间可以通过安装孔5进行安装，可将安装孔5设置在第一限位结构112与第二限位结构113的周缘，从而利用螺丝与安装孔5配合来进行安装固定，确保安装可靠性。并且，该安装孔5还可以设置在第一盖体12与第二盖体13的周缘，以通过螺丝同时将盖体与限位结构进行固定。另外，该第一限位结构112与第一盖体12之间、第二限位结构113与第二盖体13之间可以设置有密封圈4进行密封，除此之外，该第一限位结构112与第一盖体12之间、第二限位结构113与第二盖体13之间还可以采用注胶或者胶纸的方式确保两者之间的密封性能。
在一些实施例中，第一限位结构112与第二限位结构113具有用于空气流通的网状结构，该网状结构不仅可以对折叠膜进行限位，使得折叠膜限位在第一限位结构112与第二限位结构113之间，提升该产品的结构可靠性，还能够避免影响到腔体内的空气流动效果，确保增湿组件内部的水分传递效率。
在另一些实施例中，除了将第一限位结构112与第二限位结构113设置成具有网状结构以外，还可以设置一个或多个用于对折叠膜进行限位的梁状结构或者是挡板结构，该梁状结构或挡板结构的具体放置方式及实现形式可以根据实际情况而定。
进一步的，第一限位结构112与第二限位结构113可以共同构成框架结构，从而在对折叠膜具有一定的支撑与保护作用的前提下，可将其设置为可拆式连接，用户可以通过拆卸第一限位结构112与第二限位结构113即可取出或放入折叠膜，便于用户对折叠膜进行拆卸更换，降低维护成本。当然，该第一限位结构112与第二限位结构113也可以是一体成型，具体方式不限。
在一实施例中，该第一缓流结构还包括设置于第一盖体12和/或第二盖体13上的隆起部32，以及位于隆起部32至少一侧的缓坡面33。该隆起部32设于靠近第一盖体12和/或第二盖体13的进出口处，该缓坡面33在靠近隆起部32的一侧往远离隆起部32的一侧的方向上，与折叠膜之间的距离递减。
其中，该隆起部32所对应的腔体一侧与进出口连通，并且该隆起部32的顶部与折叠膜之间的距离可以大于或等于进出口的管体顶部至折叠膜之间的距离，从而确保隆起部32对应的腔体具有一定的空间，使得内部可容纳一定量的空气。该缓坡面33从隆起部32靠近进出口的一侧往原理进出口的一侧往内延伸，使得该缓坡面33在不同侧处与折叠膜之间的距离不同，利用缓坡面33的结构特点进一步控制内部空气的流速，从而提高空气与折叠 膜之间的水分传递效率，进而在确保相同增湿性能下能够有效减小增湿组件的体积。
请参阅图5，图中示出了本申请实施例提供的一种增湿组件的外部结构示意图。
如图5所示，包括第二盖体13，该第二盖体13上设置有干进口131与干出口132。该干进口131与干出口132与第二盖体13的连接处设置有隆起部32，该隆起部32的顶部与折叠膜之间的距离，与该干进口131、干出口132的顶部至折叠膜之间的垂直距离相当。并且，该隆起部32的四周设置有缓坡面33，该缓坡面33自于隆起部32连接的一侧往远离该隆起部32的方向一侧倾斜，使得该缓坡面33在靠近隆起部32的一侧往远离隆起部32的一侧的方向上，与折叠膜之间的距离递减。
具体的，该第二盖体13还设置有缓流脊31，该缓流脊31设置在干出口132与干进口131之间，使得该第二盖体13所形成的第二腔体大致分成两部分，并通过缓流脊31与折叠膜之间的空隙进行连通。另外，该干进口131与干出口132可以是设置于第二盖体13的相对两侧并且为反向设置。通过将干进口131与干出口132反向设置，能够优化气流路径，从而便于增湿组件的安装与应用，还可以提升气流与折叠膜之间的风道效果。可以理解的，该干进口131与干出口132的设置方向可以根据实际情况而定，例如设置成同向或者呈其他角度，本申请对此不做限定。
请结合图6，图中示出了本申请实施例提供的另一内部风道的结构。
结合图6，干入口的气流进入到隆起部32对应的腔室后，依次经缓坡面33、缓流脊31的减速，使得该气流停留在增湿组件内部的时间更长。并且，该气流受缓坡面33、缓流脊31的结构特征的引导，使得气流在触碰到缓坡面33及缓流脊31时往折叠膜的方向移动，更容易进入到折叠膜的不同折叠结构之间的缝隙中，从而让空气与折叠结构之间的缝隙的折叠膜表面进行更充分的接触，能进一步提升折叠膜与空气之间的水分传递效率。
可以理解的，上述结构方式除了应用于第二盖体13以外，还可以应用于第一盖体12内，从而确保带有水汽的气流能够更加充分地接触折叠膜，进而使得折叠膜与带有水汽的空气之间的水分传递效率更高，提升折叠膜的储水效果。
请参阅图7，图中示出了本申请实施例提供的增湿组件的另一种外部结构。
该增湿组件的外部结构可应用于第一盖体12。该第一盖体12可以包括湿进口131与湿出口132，在第一盖体12的中部、或者湿进口131与湿出口132之间的位置处，设置有用于减缓气流流速的缓流脊31。该缓流脊31沿气流方向上的宽度可以设置得较大，例如设置成大于 盖体在气流方向宽度的四分之一，如此可以更好地确保从湿进口131进入的气流可以充分流经折叠膜的不同折叠结构之间的空隙，进而提升该折叠膜与空气之间的水分传递效果。
另外，该第一盖体12的缓坡面33设置在隆起部32相对于进出口的另一侧，并与进出口的方向相对，如此设置可以使得气流进入或流出时可以相应地通过缓坡面33来减缓气流速度，从而确保气流能够更充分地与折叠膜进行接触。
进一步的，该至少一缓坡面33设置于第一盖体12和/或第二盖体13的进出口与缓流脊之间；或者至少一缓坡面33设置于第一盖体12和/或第二盖体13正对并远离进出口的一侧。通过上述设置，可以使缓坡面33有效提高其缓流功能。
可以理解的，上述结构除了应用于第一盖体12外，还可以应用于第二盖体13，除此之外该隆起部32、缓坡面33以及缓流脊31的不同缓流结构的设计方式，第一盖体12与第二盖体13可以同时采用图5与图7中的方式，也可以单独采用图5或者图7的方式，上述设计均可以根据实际情况而进行调整。显然，上述设计能够提高空气与折叠膜之间的水分传递效率，进而在确保相同增湿性能下能够有效减小增湿组件的体积。
