Abstract

本发明涉及一种热电池(1)，该热电池包括腔室，该腔室具有流体入口和出口，并且容纳至少一个管(3)形式的封装的相变材料，其中，至少一个管(3)在所述腔室内以螺旋状卷绕。

Description

具有封装的相变材料的热电池
技术领域
本公开涉及热电池领域，更具体地涉及一种具有相变材料的热电池。
背景技术
热电池通常用于加热车辆内部，特别是在电动和混合动力车辆中，或用于预热热管理回路中的热传递流体。热电池也可用于预热具有内燃发动机的车辆的发动机油或自动变速器流体。
具有相变材料的热电池通常包括外壳，外壳形成在其内部通常以封装形式放置相变材料的存储器。因此，热电池的性能取决于其能够容纳的相变材料的量，以及流体在储存器内以尽可能低的压降循环的需要。
发明内容
因此，本发明的目的之一是至少部分地克服现有技术的缺点，并提出一种改进的热电池。
因此，本发明涉及一种热电池，所述热电池包括外壳，外壳包括具有流体入口和出口的；并且包括在所述外壳内的至少一个管形式的内部封装的相变材料，其中，至少一个管以螺旋形状卷绕在外壳内。
相变材料的至少一个管被以螺旋形状卷绕在外壳内意味着热电池中的相变材料的量可以最大化，从而提高电池的效率，因为这种电池具有更高的热容量。
根据本发明的一个方面，所述管的螺旋状卷绕围绕平行于所述热电池内的流体的循环流动的卷绕轴线进行。
根据本发明的另一方面，管的螺旋状卷绕部包括沿着卷绕轴线的空的中心部分。
根据本发明的另一方面，热电池包括封装的相变材料的纵向管，所述纵向管被定位在管的螺旋状卷绕部的中心部。因此，纵向管填充在螺旋状卷绕部的中心部分，因而进一步增加了热电池中容纳的相变材料的量。
根据本发明的另一方面，热电池包括管之间的间隔件，以便产生用于流体循环的空间。
根据本发明的另一方面，管的螺旋状卷绕部使用单个管进行。
根据本发明的另一方面，管的壁由塑料制成。
附图说明
通过阅读下文中的以非限制示例性实施例给出的描述和附图，本发明的特点和优势将更加清晰，附图中：
图1是根据第一实施例的热电池内封装的相变材料的管的布置的示意性透视图；
图2是根据第二实施例的热电池内封装的相变材料的管布置的示意性透视图。
在各附图中，相同的元件具有相同的附图标记。
具体实施方式
热电池1通常包括外壳(未示出)，该外壳优选为绝热的，包括流体入口和流体出口。至少为管3形式的封装的相变材料设置在外壳内部。如图1和图2所示，至少一个管3以螺旋状卷绕，并且布置在外壳内。
相变材料的至少一个管3被在外壳内卷绕为螺旋状意味着热电池1中的相变材料的量可以最大化，从而提高电池的效率，因为这种电池具有更高的热容量。
该管3的螺旋状卷绕部优选围绕卷绕轴线A进行，该卷绕轴线A与所述热电池3内的流体循环流动(由图1和图2中的箭头所示)平行，使得流体可以垂直于螺旋状卷绕部循环。
热电池1内的螺旋状卷绕部优选使用单个管3进行。这使得可能限制端部的数量。具体地，在每个其端部处，容纳相变材料的管3具有焊接部或塞，以便封装所述相变材料。限制管3的数量，并且因此限制管端部的数量，使得可能降低相变材料泄漏的风险。
然而，在不脱离本发明的范围的情况下，完全可以设想在外壳内由多个管构成螺旋状卷绕部，或者多个螺旋状卷绕部的叠堆。
在其内部封装的相变材料的管3优选地由塑料制成，以允许形成这种螺旋状卷绕部。
由于管3的受限的弯曲半径，所以螺旋卷绕部沿着卷绕轴线A具有空的中心部分5。该中心部分可以保持为空的，以确保流体的良好循环，如图1所示。例如，管3由诸如聚碳酸酯的塑料制成，其中在没有管3纽绞的情况下的最小弯曲半径为25mm量级。空的中心部分5将于是具有50毫米的直径的量级。
或者，如图2所示，该中心部分5可以用封装的相变材料的纵向管7填充。这些纵向管7于是与卷绕轴线A平行设置。
因此，这些纵向管7填充在螺旋状卷绕部的中心部分5中，并且因而进一步增加容纳在热电池内的相变材料的量。
为了使流体能够在限制的压降下在管3的螺旋状卷绕部的匝之间和纵向管7之间循环，管3和纵向管7可以包括间隔件，以便产生用于流体循环的空间。
因此，可以清楚地看出，热电池1由于封装的相变材料的至少一个管3的特殊的螺旋状布置而被优化，这使得可能最大化相变材料的量。
