Description

旋转式热交换器装置
技术领域
本发明涉及一种特别用于具有热回收的分散式通风设备中旋转式热交换器装置，所述装置包括旋转式热交换器和驱动电机。
背景技术
从DE 20 2009 009 697U1中已知一种这样的旋转式热交换器装置。在该旋转式热交换器装置中，驱动电机是外转子电机，其被布置为邻近该旋转式热交换器的外壁并且其转子通过与外壁的直接形状配合和/或摩擦耦合来直接驱动该旋转式热交换器。
旋转式热交换器的外壁与转子之间借助形状配合和/或摩擦耦合的耦合需要驱动电机和旋转式热交换器相对于彼此的高位置精度以及因此的高组装成本。此外，即使在低磨损的情况下，也存在耦合不再可靠起作用的风险。
发明内容
本发明的目的是提供一种增强型的旋转式热交换器装置，所述装置特别地需要缩减的组装成本并且具有提高的可靠性。
该目的在根据权利要求1的前序部分所述的旋转式热交换器单元的情况下，通过驱动电机被布置在旋转式热交换器的转轴上，并且驱动电机的转子刚性地连接到旋转式热交换器而实现。
特别优选地，转子的转轴和热交换器的转轴是同轴的。
驱动电机优选地位于旋转式热交换器内并且转子在此优选地直接耦合到旋转式热交换器的内表面。可替代地，转子刚性地连接到旋转式热交换器的转轴，旋转式热交换器固定在所述转轴上。
在当前的情况下，转子始终意味着驱动电机的刚性地连接到旋转式热交换器并使其转动的一部分。相比之下，定子意味着驱动电机的刚性地连接到外壳的一部分。
驱动电机有利地布置成使得旋转式热交换器的转轴和驱动电机的转子的转轴同轴，并且转子刚性地连接到旋转式热交换器并在运行中使旋转式热交换器以期望的转速围绕其转轴旋转。驱动电机在此优选通过合适的电子调控设备或调控软件来设计成使得其转子以对于旋转式热交换器而言所需的转速旋转。优选不需要传动装置。
这种旋转式热交换器还特别地包含一种优势，即无需易于磨损的耦合装置，比如传动皮带、齿轮或其他装置来在转子和旋转式热交换器之间产生形状配合或摩擦耦合。这就节省了对耦合装置和/或驱动电机的复杂校准和再调整。
驱动电机不再被布置为邻近旋转式热交换器的外壁使得在旋转式热交换器装置的外壳大小不变的情况下其直径能够扩大，这在相同的空气动力性能下导致更高的热回收和更低的压力损失。
附图说明
从以下描述的和在附图中示出的示例性实施例以及从属权利要求获得本发明的更多细节、特征和有利的扩展，从属权利要求的公开内容和权利要求1的公开内容在此被并入本说明书中。
附图中示出：
图1示出第一示例性实施例的平行于的转轴的横截面示意图，
图2示出第二示例性实施例的平行于转轴的横截面示意图，以及
图3示出第三示例性实施例的平行于转轴的横截面示意图。
具体实施方式
图1至3分别示出具有例如(比如由金属薄片或合成材料制成的)立方形外壳2、电力驱动电机3和圆柱形旋转式热交换器4的旋转式热交换器装置1的示例性实施例。外壳2在侧面包括开口(未示出)，以使空气进入旋转式热交换器4和从其排出。
在根据图1和图2的示例性实施例中，驱动电机3被布置在旋转式热交换器4内，以使得驱动电机3的转子32的转轴，即电机转轴31与旋转式热交换器4的转轴(以下称为热交换器转轴41)是同轴的。
转子32例如借助旋转式热交换器4和转子32之间的齿接或螺旋连接来刚性地连接到旋转式热交换器4。
驱动电机3的定子(未示出)例如借助合适的螺纹联接来刚性地连接到外壳2的侧壁21。
滚珠轴承6在套筒5的与驱动电机3相对的一侧布置于所述套筒中，以能够旋转地支撑旋转式热交换器4，所述滚珠轴承固定在外壳2上。
在旋转式热交换器运行时，驱动电机3的转速以及因此的旋转式热交换器4的转速借助合适的电子调控设备(未示出)和调控软件来设定。
第一和第二示例性实施例之间的不同之处在于
-在根据图1的第一示例性实施例中，旋转式热交换器4的转子储存质量布置在优选的圆柱形套筒上，驱动电机3插入在该套筒中并且该套筒如上所述刚性地连接到该驱动电机的转子32，和
-在根据图2的第二示例性实施例中，旋转式热交换器4的转子储存质量直接布置在载体上，所述载体是驱动电机3的转子32的一部分。
根据图3的第三示例性实施例与上述两个示例性实施例的不同之处在于：驱动电机3布置在外壳2的外面并且其转子32经由合适的连接装置穿过该外壳的侧壁21连接到旋转式热交换器4。如下描述了原理上适用的转子储存质量或旋转式热交换器以及它们的工作原理：

http://www.lautner.eu/rotorsysteme/geraetebeschreibungen/rotor bauart.html
http://www.lautner.eu/rotorsysteme/geraetebeschreibungen/rotor typen.html
在所有的示例性实施例中，驱动电机能够被实现为外转子电机或内转子电机的形式。
本发明不限于所描述和图示的示例性实施例，而是包括在本发明的意义内设计和起作用的所有实施例。此外，本发明还不限于权利要求1中限定的特征组合，而是也能够通过其他的一起公开的所有单独特征的选定特征的任意所需组合来限定。
