Description

多盘管微通道热交换器及空调机组 技术领域
本申请涉及热交换器技术领域，尤其涉及一种多盘管微通道热交换器及空调机组。
背景技术
微通道热交换器(Micro-Channel Heat Exchanger，MCHE)通常包括入口集管、出口集管以及连接到这些集管并与这些集管连通的多个扁平管。每个扁平管都具有微通道或小的路径以供制冷剂(气体或液体)通过。在运行期间，在微通道热交换器中，制冷剂通过入口集管的入口进入入口集管，然后制冷剂进入具有微通道的扁平管，并且在制冷剂在扁平管内流动时，制冷剂与扁平管外部的流体(例如，空气)进行热交换。与外部流体进行热交换后，制冷剂离开扁平管，进入出口集管，并通过出口集管的出口离开出口集管。
目前，在空调机组中通常使用这种微通道热交换器的蒸发器或冷凝器。然而，在较大吨位的空调机组中，如果将微通道热交换器做成单个盘管的话，则盘管的长度将会非常大。首先，盘管的长度会受到制造生产的限制，提供盘管的供应商的制造炉通常没有那么大；其次，这会使得进口集管(Header)的分配管的长度也会相应地需要很长而导致分配难度将会变得非常大。因此，在设计时，通常选择将微通道热交换器做成两片或多片盘管的形式，从而来满足用户对于容量的需求。
由特灵国际有限公司于2020年4月30日申请的美国专利申请US2021/03411889A1公开了一种多板微通道的热交换器。该多板微通道的热交换器包括位于近侧的第一板、位于远侧的第二板、第一入口连接器、第一出口连接器、第二入口连接器及第二出口连接器。第一板包括第一入口集管、第一出口集管及连接第一入口集管和第一出口集管的多个第一管。第二板包括第二入口集管、第二出口集管及连接第二入口集管和第二出口集管的多个第二管。第一入口连接器流体连接到第一入口集管，第一出口连接器流体连接到第一出口集管，第二入口连接器流体连接到第二入口集管，第二出口连接器流体连接到第二出口集管。其中，第一板和第二板沿着所述多板微通道的热交换器的长度方向上相继布置。该多板微通道的热交换器具有沿长度方向的第一端和第二端，第一入口连接器、第一出口连接器、第二入口连接器及第二出口连接器设置在第一端。第一板具有第一迎风面，第二板具有第二迎风面。然而，由于第一板的第一迎风面和第二板的第二迎风面位于同一个 平面，因此，远侧的第二板的第二入口连接器和第二出口连接器必须走近侧的第一板的底部穿过，第二入口连接器和第二出口连接器将会占去近侧的第一板的一部分面积。所以，在整个多板微通道的热交换器的面积一定的情况下，必然会导致近侧的第一板的迎风面积相对于远侧的第二板的迎风面积变小。

第一实施例
图1至图3揭示了本申请第一实施例的多盘管微通道热交换器100的图示，其中，图1揭示了多盘管微通道热交换器100的透视图；图2揭示了多盘管微通道热交换器100的正视图；图3揭示了多盘管微通道热交换器100的左视图。
多盘管微通道热交换器100具有长度方向D1、垂直于长度方向D1的高度方向D2、以及垂直于长度方向D1和高度方向D2的厚度方向D3。以下将以这些方向为基准来描述多盘管微通道热交换器100中各个组成元件的相对位置关系。
如图1至图3所示，多盘管微通道热交换器100包括位于近侧的第一盘管110和位于远侧的第二盘管120。近侧是指对多盘管微通道热交换器100能够容易地执行维护或保养过程的一侧。例如，对于图1和图2，近侧可以对应于纸的左侧，而远侧则可以对应于纸的右侧。
第一盘管110包括第一入口集管150、第一出口集管160和多个第一微通道管110A。第一入口集管150和第一出口集管160均具有长度L1，第一入口集管150和第一出口集管160均沿着多盘管微通道热交换器100的长度方向D1延伸。多个第一微通道管110A在沿着第一盘管110的长度方向(即多盘管微通道热交换器100的长度方向)D1上相继布置。每一个第一微通道管110A可以是在第一盘管110的高度方向(在本实施例中即多盘管微通道热交换器100的高度方向D2)上延伸的扁平多端口管。在一个实施例中，相邻两个第一微通道管110A之间通常还具有钎焊在其间的翅片(未图示)。每一个第一微通道管110A包括入口和出口，多个第一微通道管110A的入口与第一入口集管150流体连通，多个第一微通道管110A的出口与第一出口集管160流体连通。

第二盘管120包括第二入口集管170、第二出口集管180和多个第二微通道管120A。第二入口集管170和第二出口集管180均具有长度L2，第二入口集管170和第二出口集管180均沿着多盘管微通道热交换器100的长度方向D1延伸。多个第二微通道管120A在沿着第二盘管120的长度方向D1(即多盘管微通道热交换器100的长度方向D1)上相继布置。每一个第二微通道管120A可以是在第二盘管120的高度方向D2上延伸的扁平多端口管。在一个实施例中，相邻两个第二微通道管120A之间通常还具有钎焊在其间的翅片(未图示)。每一个第二微通道管120A包括入口和出口，第二入口集管170与多个第二微通道管120A的入口流体连通，第二出口集管180与多个第二微通道管120A的出口流体连通。
第二盘管120还包括第二支架140B。在一个实施例中，第二支架140B可以是由铝或铝合金制成的在第二盘管120的高度方向D2上从第二盘管120的顶部延伸到底部的扁平板。第二支架140B固定到第二盘管120的第一根第二微通道管120A(即在第二盘管120的长度方向D1上位于第二盘管120的最左端的第二微通道管120A)。第二盘管120还包括第二端部支撑件130B。 第二端部支撑件130B可以是在第二盘管120的高度方向(在本实施例中即多盘管微通道热交换器100的高度方向D2)上从第二盘管120的顶部延伸到底部的扁平板。第二端部支撑件130B固定到第二盘管120的最后一根第二微通道管120A(即在第二盘管120的长度方向D1上位于第二盘管120的最右端的第二微通道管120A)。
第一盘管110和第二盘管120本质上沿着多盘管微通道热交换器100的长度方向D1相继布置。通过第一盘管110的第一支架140A和第二盘管120的第二支架140B之间的相互配合安装，从而，可以将第一盘管110和第二盘管120连接在一起。
多盘管微通道热交换器100还包括第一入口连接器199A和第一出口连接器199B、以及第二入口连接器199C和第二出口连接器199D。其中，第一入口连接器199A流体连接到第一入口集管150，第一出口连接器199B流体连接到第一出口集管160。第二入口连接器199C流体连接到第二入口集管170，第二出口连接器199D流体连接到第二出口集管180。
多盘管微通道热交换器100还包括第一入口导管191和第一出口导管192、以及第二入口导管193和第二出口导管194。其中，第一入口导管191通过第一入口连接器199A连接到第一入口集管150，第一出口导管192通过第一出口连接器199B连接到第一出口集管160，第二入口导管193通过第二入口连接器199C连接到第二入口集管170，第二出口导管194通过第二出口连接器199D连接到第二出口集管180。
多盘管微通道热交换器100具有沿长度方向D1上的第一端和第二端。第一入口连接器199A、第一出口连接器199B、第二入口连接器199C和第二出口连接器199D均位于多盘管微通道热交换器100的第一端(如图1所示的纸的左端)。通过将第一入口连接器199A、第一出口连接器199B、第二入口连接器199C和第二出口连接器199D布置在多盘管微通道热交换器100沿长度方向D1上的同一端，从同侧进出，从而使得多盘管微通道热交换器100所使用的进出口管路的总长可以相对减小。
如图1和图2所示，第一盘管110包括第一迎风面S11，第一盘管110的长度为L1，高度为H，第一迎风面S11的面积＝L1×H；第二盘管120包括第二迎风面S12，第二盘管120的长度为L2，高度为H，第二迎风面S12的面积＝L2×H。
如图1所示，第一盘管110的第一迎风面S11和第二盘管120的第二迎风面S12分别位于不同的平面。在本实施例中，如图3所示，沿着多盘管微通道热交换器100的长度方向D1看，第一盘管110的第一迎风面S11与第 二盘管120的第二迎风面S12相互平行，并且，第一迎风面S11与第二迎风面S12平行于多盘管微通道热交换器100的高度方向D2。
在图1至图3示出的多盘管微通道热交换器100为一种双程热交换器。第一入口集管150、第一入口连接器199A、第二入口集管170和第二入口连接器199C以及第一出口集管160、第一出口连接器199B、第二出口集管180和第二出口连接器199D均位于多盘管微通道热交换器100的底部。
其中，第一入口集管150和第一出口集管160位于第一盘管110的底部，第二入口集管170和第二出口集管180位于第二盘管120的底部。由于第一盘管110的第一迎风面S11和第二盘管120的第二迎风面S12位于不同的平面并相互平行，第一盘管110和第二盘管120可以在沿着多盘管微通道热交换器100的厚度方向D3上相继排列，因此，第二入口连接器199C与第一入口集管150可以沿多盘管微通道热交换器100的厚度方向D3布置，第二出口连接器199D与第一出口集管160可以沿多盘管微通道热交换器100的厚度方向D3布置。位于远侧的第二入口连接器199C和第二出口连接器199D可以无需经过位于近侧的第一盘管110的底部延伸穿过，而可以从位于近侧的第一盘管110在沿多盘管微通道热交换器100的厚度方向D3上的一侧延伸穿过。所以，位于近侧的第一盘管110的高度无需减少，位于远侧的第二入口连接器199C和第二出口连接器199D不会占用位于近侧的第一盘管110的迎风面积。如图1和图2所示，第一盘管110的第一入口集管150和第一出口集管160、以及第二入口连接器199C和第二出口连接器199D可以分别沿着多盘管微通道热交换器100的厚度方向D3排布。
在一些实施例中，第一盘管110和第二盘管120可以相同。第一盘管110和第二盘管120具有相同的长度，即L1＝L2，因此，第一盘管110的第一迎风面S11和第二盘管120的第二迎风面S12可以具有相同的迎风面积。由于本申请的多盘管微通道热交换器100可以采用相同的盘管来构成，从而，可以简化多盘管微通道热交换器100的结构和制造工艺，降低成本。
在多盘管微通道热交换器100运行时，制冷剂首先从多盘管微通道热交换器100的第一入口导管191和第二入口导管193流入，通过第一入口连接器199A和第二入口连接器199C分别流入到第一入口集管150和第二入口集管170，然后，制冷剂分别进入第一盘管110的第一微通道管110A和第二盘管120的第二微通道管120A中，从多盘管微通道热交换的底部经过第一盘管110的第一微通道管110A和第二盘管120的第二微通道管120A分别到达多盘管微通道热交换的顶部，然后，在多盘管微通道热交换的高度方向D2上从多盘管微通道热交换的顶部再向下流到底部。在制冷剂在第一微通道管110A和第二微通道管120A内流动时，制冷剂分别与第一微通道管110A和第 二微通道管120A外部的流体(例如，空气)进行热交换。在与外部流体进行热交换之后，制冷剂分别离开第一微通道管110A和第二微通道管120A，接着，分别流入到第一出口集管160和第二出口集管180，最后，分别通过第一出口连接器199B和第二出口连接器199D流入第一出口导管192和第二出口导管194。从而，完成热交换的过程。
上面所述的多盘管微通道热交换器100是以将进出口管路设置在底部作为示例来进行说明的。当然，在其他一些实施例中，多盘管微通道热交换器100也可以将进出口管路设置在顶部，其并不改变本申请的创作实质，这些等同或微小变换仍将在本申请所附的权利要求书的保护范围之内。
第一实施例的多盘管微通道热交换器100在缩短远侧的进出口管路的长度的基础上，能够充分利用空调机组的截面积，增大盘管的迎风面积。
以上是以多盘管微通道热交换器100为一种双程热交换器为例来进行示意性说明的。然而，本申请第一实施例的多盘管微通道热交换器100并不局限于双程热交换器。在另一些实施例中，本申请第一实施例的多盘管微通道热交换器100也可以为一种单程热交换器。
图4揭示了一种单程热交换器的结构示意图，在图4中仅示出第一盘管110和第二盘管120的集管和微通道管。如图4所示，箭头指示制冷剂的流动方向。将理解的是，图4所示的单程热交换器可以具有与图1至图3所示的双程热交换器相同/相似的部件。与图1至图3所示的双程热交换器的区别在于，对于图4所示的单程热交换器来说，第一入口集管150、第一入口连接器、第二入口集管170和第二入口连接器位于多盘管微通道热交换器100的底部，而第一出口集管160、第一出口连接器、第二出口集管180和第二出口连接器位于多盘管微通道热交换器100的顶部，反之亦然。
其中，第一入口集管150位于第一盘管110的底部，第二入口集管170位于第二盘管120的底部；第一出口集管160位于第一盘管110的顶部，第二出口集管180位于第二盘管120的顶部。位于远侧的第二入口连接器与位于近侧的第一盘管110的第一入口集管150可以在多盘管微通道热交换器100的底部沿着多盘管微通道热交换器100的厚度方向D3排布；而位于远侧的第二出口连接器与位于近侧的第一盘管110的第一出口集管160则可以在多盘管微通道热交换器100的顶部沿着多盘管微通道热交换器100的厚度方向D3排布。
因此，位于远侧的第二入口连接器和第二出口连接器无需占用位于近侧的第一盘管110的迎风面积，进而，位于近侧的第一盘管110可以和位于远侧的第二盘管120一样具有较大的迎风面积。
以上所述是以多盘管微通道热交换器100包括两片盘管为例来进行示意性说明的。然而，本申请的多盘管微通道热交换器100并不局限于包括两片盘管。

相应地，本申请的多盘管微通道热交换器100还包括第一入口连接器199A和第一出口连接器、第二入口连接器199C和第二出口连接器、以及第三入口连接器199E和第三出口连接器(未图示)。第一入口连接器199A流体连接到第一入口集管150，第一出口连接器流体连接到第一出口集管160。第二入口连接器199C流体连接到第二入口集管170，第二出口连接器流体连接到第二出口集管180。第三入口连接器199E流体连接到第三入口集管940，第三出口连接器流体连接到第三出口集管950。
在图5和图6中，第一盘管110、第二盘管120及第三盘管930本质上可以在沿着多盘管微通道热交换器100的长度方向D1上相继布置，并且，第一盘管110、第二盘管120及第三盘管930在沿着多盘管微通道热交换器100的厚度方向D3上也相继布置，从而可以使得第一盘管110的第一迎风面S11、第二盘管120的第二迎风面S12及第三盘管930的第三迎风面S93均位于不同的平面，进而方便远侧盘管的进出口管路的排布，而无需占用近侧盘管的迎风面积。因此，第一盘管110、第二盘管120及第三盘管930可以具有相同的迎风面积。
在图5所示的双程热交换器中，第一入口集管150、第一出口集管160、第一入口连接器199A、第一出口连接器、第二入口集管170、第二出口集管180、第二入口连接器199C、第二出口连接器、第三入口集管940、第三出口集管950、第三入口连接器199E及第三出口连接器均位于多盘管微通道热交换器100的底部(或者顶部)。并且，第一入口集管150、第一出口集管160、第二入口连接器199C、第二出口连接器、第三入口连接器199E及第三出口连接器沿着多盘管微通道热交换器100的厚度方向D3排布。

图7和图8示出本申请第二实施例的多盘管微通道热交换器200可以为一种双程热交换器。对于双程热交换器，第一入口集管250、第一入口连接 器299A、第二入口集管270和第二入口连接器299C以及第一出口集管260、第一出口连接器299B、第二出口集管280和第二出口连接器299D均位于多盘管微通道热交换器200的底部(或者顶部)。其中，第一入口集管250和第一出口集管260位于第一盘管210的底部(或者顶部)，第二入口集管270和第二出口集管280位于第二盘管220的底部(或者顶部)。第一盘管210的第一入口集管250和第一出口集管260、以及第二入口连接器299C和第二出口连接器299D可以在多盘管微通道热交换器200的底部(或者顶部)沿着多盘管微通道热交换器200的厚度方向D3排布。

通过将两层盘管在多盘管微通道热交换器800的高度方向D2上采用这种错位排布的方式，从而，可以充分利用整个空调机组的截面积，位于外层的第一层盘管801几乎不会对位于内层的第二层盘管802的迎风面积造成大的影响，因此，位于内层的第二层盘管802也可以保持较大的迎风面积，进而使得多盘管微通道热交换器800的整个迎风面积可以尽可能地增大。
在一些实施例中，第一层盘管801和第二层盘管802可以相同。因此，本申请第八实施例的多盘管微通道热交换器800可以采用相同的盘管来构成，从而可以大大简化结构，简化制造和生产工艺，降低成本。
在一些实施例中，多盘管微通道热交换器800还可以包括导流板，导流板连接第一层盘管801的上端及第二层盘管802的下端。导流板倾斜设置，从而，可以在位于内层的第二层盘管802的迎风面一侧形成较大的喇叭口，增大外部流体的流动量，进而，可以增大位于内层的第二层盘管802的迎风面积。
第八实施例的多盘管微通道热交换器800在缩短远侧的进出口管路的长度的基础上，能够充分利用空调机组的截面积，进一步增大盘管的迎风面积，能够满足更大的换热需求，适用于更大吨位的空调机组。
以上列举出本申请的多盘管微通道热交换器的多个实施例，然而，本申请的多盘管微通道热交换器并不局限于上面各个实施例所述。综合上面各个实施例所述，本申请的多盘管微通道热交换器可以包括沿多盘管微通道热交换器的高度方向D2上排布的一层或多层盘管。每一层盘管可以包括本质上沿着多盘管微通道热交换器的长度方向D1相继布置的两片或多片盘管。
其中，对于同一层盘管来说，同一层盘管中的所有盘管的迎风面均位于不同的平面，从而可以使得远侧的进/出口连接器无需经过近侧的盘管的底部，而可以从近侧的盘管在多盘管微通道热交换器的厚度方向D3上的一侧延伸穿过，远侧的进/出口连接器和近侧盘管的进/出口集管可以在沿着多盘管微通道热交换器的厚度方向D3上排布。从而，近侧的盘管的高度不用减少，可以增大近侧的盘管的迎风面积。
而对于不同层盘管来说，不同层盘管在多盘管微通道热交换器的高度方向D2上相互错位布置。即，不同层盘管分别位于不同的高度，并且，相邻层盘管在多盘管微通道热交换器的高度方向D2上部分重叠。
本申请还提供了一种空调机组。该空调机组可以包括以上各个实施例所述的多盘管微通道热交换器100-800。
本申请各个实施例所述的多盘管微通道热交换器100-800及具有该多盘管微通道热交换器100-800的空调机组在缩短远侧的进出口管路的长度基础上，能够增大盘管的迎风面积。
以上对本申请实施例所提供的多盘管微通道热交换器及空调机组进行了详细的介绍。本文中应用了具体个例对本申请实施例的多盘管微通道热交换器及空调机组进行了阐述，以上实施例的说明只是用于帮助理解本申请的核心思想，并不用以限制本申请。应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请的精神和原理的前提下，还可以对本申请进行若干改进和修饰，这些改进和修饰也均应落入本申请所附权利要求书的保护范围内。
