Description

潜热存储装置
技术领域
本发明涉及一种用于内燃机，特别是机动车辆内燃机的排气系统的潜热存储装置。
背景技术
潜热存储装置更优选的特征在于使用用于热存储的相变材料。所述的相变材料，其通常为盐，在各自所需的存储温度下在液相和固相之间进行相变。当供热给潜热存储装置时，储热材料熔化，而在释放热量时，储热材料固化。低于存储温度时，即低于相变材料的相变温度时，由此形成的潜热存储装置只能存储显热，即以固态的相变材料的温度提高的形式。当相变材料被加热到其相变温度时，它就熔化了，通过相变进行潜热储存。在这个过程中，由此储存的热量被存储在存储温度的温度水平，并且也能在这个温度重新获得。另外，液态的相变材料能被额外加热，这相应地导致显热即温度依赖型热量存储。通过选择相变材料，潜热存储装置的存储温度能够适应潜热存储装置的相应操作目的。
为了更好的应用于车辆，潜热存储装置能够使内燃机或者排气系统的单独组成部件在操作温度下保持尽可能长的时间，以提高内燃机或者内燃机相应组成部件的效率。由于所述潜热存储装置的关注度不断提高，为了更好的适应系列生产，需要寻找更划算的制造方案。
发明内容
本发明提供一种关于开头所述类型的潜热存储装置的改进实施例，用以解决上述问题，其更优选的特征在于其能相当划算的生产。
根据本发明，该问题通过独立权利要求的主题得到解决。更优选的实施例均在从属权利要求的主题中体现。
本发明是基于这样一个基本的想法，即通过层结构形成潜热存储装置的存储主体，所述层结构在多个板的协助下产生。其中，至少一个板是波纹状的。这些板彼此邻接并且彼此固定。因此，至少一个板上的波纹在存储主体内部形成沟槽，所述沟槽互相平行并且至少其中的一些能被相变材料填充。所述多个板的层结构更优选的能够简单并且划算地生产，并且也更合适于系列生产。
所述两个板可以沿着接触线彼此邻接并且沿着所述接触线彼此固定，如通过焊缝或者焊接头。为了减少由存储主体内的热量产生的压力，可以沿着某些所述的接触线设置两个彼此间松散相接的板。在这些彼此松散相接的接触线区域，所述两个板之间能够由此发生相对运动，所述相对运动能够减少在存储主体内部热应力的产生。
另外或者可选地，也可以将两个板都设置成波纹状。由此，在波纹的轴向的横向，所述板均具有一定的弯曲弹性，这能使其抵消或者吸收热应力。
本发明其他重要的特征和优点将体现在从属权利要求、附图及参照附图的相应的附图说明中。
可以理解的是，上文提到的和下文将解释说明的特征不仅仅能被用于所述的相应组合，还可以在不脱离本发明的保护范围的情况下被用于其他组合或者单独使用。
本发明的优选实施例将在附图中展示，并且通过以下附图说明进行详细解释，其中，相同的附图标记表示同样或者相似或者功能相同的部件。
附图说明
以下是各附图的说明，
图1是在潜热存储装置区域中的排气系统的高度简化的示意图。
图2到12是不同实施例中的潜热存储装置的存储主体的一部分的截面图。
具体实施例
如图1所示，优选安装在机动车辆上的内燃机(图中未示出)的排气系统1包括排气线2，潜热存储装置3设置在其中或与其结合。在壳体4内的所述潜热存储装置3包括存储主体5，该存储主体5具有多个互相平行并包含相变材料7的沟槽。这里，并不是所有的沟槽6都必须被相变材料7所填充。更优选的，将一些沟槽6合并到排气线2内，由此，在排气线2内传输的废气流8能够从中流过。在图2-12的截面示意图中，被相变材料7所填充的沟槽6被标记为6′，而在图2-12中未被相变材料7所填充的即更适于废气流过的沟槽6被标记为6″。
如图2-12所示，潜热存储装置3的存储主体5由包括沟槽6的层结构9形成，并且，该层结构9在图2-12的示意图中沿着沟槽6的纵向被横向切割并且只部分显示。层结构9至少由两个板10、11形成，其中至少一个板10是波纹状的，而另一个板11在图2-6的实施例中是非波纹状的或者平滑的并且优选设置成平坦的。在图7、8、11和12的实施例中，另一个板11也是波纹状的设计。在图9和10的实施例中，另一个板11部分为波纹状而部分为非波纹状或者平坦的并且优选设计为水平的。
为了制造层结构9，两个板10、11以层的形式被设置在彼此的顶部，并且互相固定。这里，所述至少一个板10的波纹与另一个板11相连形成沟槽6。如图所示，波纹状的板10与另外板11在它的面对对应的另外板11的波峰或者波谷的顶线区域相连。因此，连接是线性的。在直线波结构的情况下，这些接触线也是线性的。沿着所述的接触线，两个板10、11优选彼此固定。合适的固定点在图2和6-12通过加黑的区域示出并且用12表示。固定点12能通过例如焊缝或者焊接头实现。
为了制造层结构9，如图2和5中弯曲表征所示，板10、11可以是卷绕的，比如说成螺旋形。同样的，也可以将两个板10、11在如图3-4和6-12所示的水平层上成对地分层堆积或堆叠在彼此的顶部。两种制造方法都能相当容易的实现并且更适合系列生产。
如图2、7、8、11和12中所示的实施例，两个板10、11沿着全部的接触线彼此固定。图6、9和10所示的是相反的实施例，其中，两个板10、11仅沿着位于填充的沟槽6′的两侧的接触线彼此固定。在剩余的接触线区域，两个板10、11彼此松散连接。所述松散接触点在图6、9和10中用13表示。这样的构造能使两个板10、11之间的相对运动成为可能。这种类型的相对运动可由于例如热膨胀作用而产生并且能在层结构9内减少热应力。
填充有相变材料7的沟槽6′能够通过固定点12在侧面被密封，出于这个目的，所示固定点12被连续配置。在其纵向端部，这些被填充的沟槽6′以合适的方式同样被密封。通过被填充的沟槽6′在端部的密封，相变材料7被封装在沟槽6′内并远离外侧，所以即使在液体状态，它能依然保持在为此目的提供的密封沟槽6′的内部。用于传送气体的沟槽6′的端部是开放的。填充沟槽6′和未填充沟槽6″的数量以及它们在层结构9内的空间排列能影响所述潜热存储装置3的储热能力和在潜热存储装置3内的热量传递。图3-5只是示意性地示出了能导致不同的存储能力和热传递速率的不同结构。另外，能用于流通的沟槽6′的数量可以由出现在排气系统1的废气流8的最大量或者由所容许的流阻而预先确定，这些也共同决定所述层结构9的设计。
更优选的，用于流通的沟槽6″能够至少部分以催化作用的方式被涂覆，由此使得在潜热存储装置3内结合催化剂成为可能。因此，在潜热存储装置3内部的热量存储和热量释放能直接的发生在需要热量或者为了供应热量存储装置3而提供热量的地方。因此，潜热存储装置3能特别有效率地工作。
为此，相变材料7能这样选择，即它的相变温度等于或者高于相应催化剂材料的起始温度。正因为这样，可以实现用于相应的催化剂的备用功能，因为在相变材料7的帮助下，所述催化剂能在相对长的时期内被保持在相变温度的温度水平。适于实现所述备用功能的催化涂层是，例如，三元催化剂(TWC)或者柴油氧化催化剂(DOC)。可选择的(或者另外的，当使用两种不同的相变材料时)，选择相变材料以使得它的相变温度在相应的催化剂的可容许的操作温度区间的上端。由此，可以避免相应催化剂的过热。如果催化剂的温度大幅升高并且达到了其操作温度区间的温度上限，那么将达到相变温度并且相变材料7熔化，从而在这个过程中吸收热量。在该潜热吸收中，催化剂温度升高被极大的降低，因此它可以免于过热。适于所述功能的催化涂层，优选是NOX储存催化剂(NSK)和粒子氧化催化剂(POC)。如上所示的，如果两种以不同的相变温度来区分的不同的相变材料7被应用在分开的沟槽6内时，则这个特别实施例的潜热存储装置3就能实现两种规定的功能。
图7-12的实施例所示的是两个板10、11均是波纹状的层结构9。这里，两个板10、11的波结构优选有相同的波长。这就意味着，两个板10、11上在两个相邻的波峰之间沿着波纹的轴向方向的横向的间距基本上是同样的大小。另外，根据这里所述的实施例，两个板10、11的波结构可以有不同的振幅。明显的是在图7-12中所示的上面的第一板10有着更大的振幅，也就是说它在波峰和波谷之间的间隔大于下面或者说是第二板11。例如，一个板10的振幅比另一个板11的大2到10倍。
如果两个板10、11都具有波纹，那么在层结构9内由于热量引起的膨胀效果能被更好的吸收或者补偿。
如图7、9和11所示的实施例，其中，板10、11相对于它们的波结构来说是彼此同步接触的。这就意味着所述一个板10的波谷与另一个板11同样的在波谷区连接。这样的结构也被指定为是双凹波配对。与此相反的是，图8、10和12示出了板10、11相对于它们的波结构来说以相位移的方式连接。明显地，所述一个板10的波谷与另一个板11在它的波峰区域连接。这样的结构也被指定为是凹凸波配对。显然其他的大于或小于半个波长的相位移也是可能的。
图9和10示出了特别的实施例，其中，在两个相邻的被填充的沟槽6′之间，至少设置有一个未被填充的沟槽6″，其中另外的，第二个板11只在被填充的沟槽6′的区域设置有相应的波形。在未被填充的沟槽6″的区域，在这些实施例中，第二个板11设置成非波纹状的或者平滑的，并且最好是水平的。图9中所示的结构也可以被指定为选择性的双凹波配对，同时图10中所示的结构也可以被指定为是选择性的凹凸波配对。
这些结构的特征在于，在多个未填充的沟槽6″在存储结构5内彼此邻接的情况下，存在更好的用以抵消热量膨胀影响的移动性。图11所示的是一种优选的关于双凹波配对用于设置相邻接的波配对或者波板对的实施例。可以看出，邻接的另外的第一板10′与完全示出的波配对的板10、11同步设置，所以面对所述波配对的第二板11的另外的第一板10上的波峰在波配对的第二板11的波峰位置相连接。通过在波配对里的同步设置，邻接板10′的接触线设置于在波配对内的接触线之间。
如图12所示的结构，同样的，另外的板10′的波峰与波配对的面对的第二板11的波峰区域接触。通过在波配对里的相位移，在另外的板10′和波配对的第二板11之间的接触线与波配对内的接触线一致。这里所述的结构用于提供一种特别紧凑的结构。
