图1a为现有技术中一种换热板的表面结构示意图。如图1a所示，现有技术的换热板包括纵横交错排布的条状凸包101和凸包102。其中，凸包101在图1a所示的第一面S1形成凸起，在与第一面S1相对的第二面形成凹陷；凸包102在图1a所示的第一面S1形成凹陷，在与第一面S1相对的第二面形成凸起。从图1a中可以看出，各条状凸包101、102之间排布较为密集。该密集排布的凸包可以使得气流与换热板之间充分的进行热交换，提高了换热板的传热系数。但是，由于凸包排布密集，导致气流的流动阻力大大增强，进而限制了流体的流动速度，从而降低数据中心的气流换热速度。
图1b为现有技术中另外一种换热板的表面结构示意图。如图1b所示，换热板表面包括呈阵列排布的多个圆形凸包。从图1b中可以看出，每一行或每一列凸包之间具有较大的间隔。通常将换热板表面设计成如此形状的凸包，可以提高流体的流动速度。然而，稀疏的凸包降低换热板表面的换热系数，从而降低冷气流与热气流之间的换热效率。
基于上述现有的换热板的表面结构存在的问题，本申请提供一种换热板以及包含该换热板的换热器，通过设置第一导流体和支撑结构以对气流进行引流，从而提高换热器的换热效率、降低气体流阻。
首先需要说明的是，本申请中所述的导流体可以包括一个凸包(例如图2所示的凸包2011、例如图8所示的凸包20131)，还可以包括如图2、图5、图14所示的实施例中沿第二方向的多个凸包(例如图2所示的导流体201)，还可以包括如图8、图10、图11、图12所示的实施例中沿第一方向一对凸包(例如图8所示的第三凸包2013)，还可以包括如图8、图10、图11、图12所示的实施例中沿第二方向的多个凸包对(例如图8所示的导流体201)。
图2为本申请实施例提供的一个换热板的表面结构示意图。在图2中，换热板20包括基板21、在基板21上形成的导流体201以及支撑结构202。
基板21包括沿第一方向x的第一边B1、第二边B2和沿第二方向y的第三边B3、第四边B4。其中，第一方向x为水平方向，第二方向y为竖直方向。基板21还包括第一表面S1、以及与第一表面S1相对的第二表面。图2中，第二表面未示出。
导流体201包括沿第二方向y间隔排布的多个凸包2011。具体的，凸包2011向基板21的正投影所形成的图案可以包括但不限于椭圆形、水滴形、长条形、三角形，其中，多个凸包2011之间可以形状相同或不同、也可以大小相同或不同。图2示意性的示出了凸包2011向基板21的正投影所形成的图案为椭圆形的情况。
支撑结构202沿第二方向y延伸。这里，支撑结构由于相对于基板21向外凸起，也可以称为支撑凸包。从图2中可以看出，支撑结构从第一边B1所在侧延伸至第二边B2的一侧。通过将支撑结构202设置成如图2所示的形状，可以提高由多个换热板20叠片装配后形成的换热器的结构强度。
这里需要说明的是，沿第二方向y，支撑结构还可以为间隔排布的多个长条状凸包，支撑结构包括的多个长条状凸包的排布方式可以与导流体201中的凸包的排布方式相同。也即是说，将如图2所示支撑结构202分割成3至5段，每两段之间设置有一定的空隙。该种情况的支撑结构在图中不再示出。
在图2所示的换热板20中，间隔排布的多个凸包2011形成的导流体201与支撑凸包形成的支撑结构202沿第一方向x交替间隔设置。各导流体沿第一方向x的间隔可以相等。从而，换热板被均匀的分隔出多个腔体。通常，换热板20的第二边B2所在侧为进风口，外部气流从B2侧流向B1侧。通过设置支撑结构202，可以将气流均匀的限制在每个腔体内，避免气流在换热板上分布不均匀，提高换热板的利用率，从而提高换热效率。
在图2所示的换热板20中，导流体201和支撑结构202可以形成于同一面，例如形成于第一面S1。也即是说，导流体201和支撑结构202的凸包朝同一方向凸起。如图3所示，图3示出了换热板20沿AA’的一个剖视图。
在一种可能的实现方式中，导流体201和支撑结构202可以形成于不同面。例如，导流体201形成于第二面S2，支撑结构202形成于第一面S1。如图4所示，图4示例性的示出了换热板20沿AA’的另外一个剖视图。
在本实施例中，基板21、导流体201和支撑结构202可以一体成型。也即是说，基板21、导流体201和支撑结构202是由相同的材料形成。这里，形成换热板20的材料可以为金属材料，也可以为非金属材料。其中，金属材料包括但不限于：铝、铜以及各种金属按照一定比例混合而成的合金材料(例如铝合金)。非金属材料包括但不限于PP(Polypropylene，聚丙烯)、PVC(Polyvinylchlorid，聚氯乙烯)、PS(Polystyrene，聚苯乙烯)、PC(Polycarbonate，聚碳酸酯)以各种非金属按照一定比例混合而成的材料。
由于金属材料具有较高的硬度，限制了所形成的凸包向外凸起的高度。通常，由金属材料形成的换热板在装配成换热器的过程中，每两个换热板之间通常设置较大的间隔，该间隔通常大于凸包向外凸起的高度，一般为凸包向外凸起的高度的两倍。因此，优选的，当换热板采用金属材料制造时，可以优先选择如图4所示的剖视图的结构，也即将导流体201设置于第二面S2、将支撑结构202设置于第一面S1的结构。这样一来，图4所示的结构可以使每两个换热板之间的间距约为凸包向外凸起的高度的2倍。其次，由于换热板的两面都具有导流结构，室外新风和室内热风可以交替在换热板的两面进行换热，从而减少了换热器中所需要的换热板的数目，节约了换热器的制造成本。
由于非金属材料PP、PVC、PS、PC等均为高分子材料，相比于金属材料，其具有低硬度、高柔韧性的特点。利用非金属材料形成的凸包可以具有较大的凸起厚度。因此，优选的，当换热板采用非金属材料制造时，可以采用如图3所示的剖视图的结构，也即将导流体201和支撑结构202设置于如图3所示的第一面S1。图3所示的结构可以使每两个换热板之间的间距大约为凸包向外凸起的高度。从而，使得换热板20的导流体201和支撑结构202更加稳固。
在一些可选的实现方式中，当采用非金属材料制造换热板时，为了进一步提高换热板20的稳定性，可以在导流体201的凸包2011之间设置有用于连接各凸包2011的加强结构，该加强结构为凸包2012，如图5所示，图5示出了本申请实施例提供的又一个换热板20的表面结构示意图。凸包2012向基板21的投影为细条状。这里，凸包2012对凸包2011具有支撑作用。通过设置凸包2012，可以使得凸包2011更加稳固，有利于提高换热板20的稳定性，进而有利于提高换热板的换热性能。这里，为了尽可能的减小换热板20的流体阻力，凸包2012沿第一方向x的宽度可以小于等于凸包2011沿第一方向x的宽度，如图5所示。这里，凸包2012沿第一方向x的宽度与凸包2011沿第一方向x的宽度之间的比例可以在[0.2，1]的范围内。
在一些可选的实现方式中，当采用非金属材料制造如图3所示的剖面结构的换热板时，由于换热板20仅有一面形成有导流体，也即为单面换流。为了提高换热器的换热效果，相比于双面形成导流体的结构，通常会多增加几片换热板(例如多增加一倍数目的换热板)。此时，为了进一步提高换热板之间的稳定性，使得换热板更加牢固，可以在换热板20设置有凸台203，如图5所示。凸台203设置于基板21上。在图5中，凸台203可以设置于如图5所示的位置处。值得注意的是，凸台203的数目不是固定的，根据应用场景的需要设置。例如，在一些实施例中，换热板可以包括四个凸台，该四个凸台可以为图5所示的左上角、左下角、右上角、右下角处四个位置的凸台。
可选的，凸台203可以设置于支撑结构202上。
换热板20上的凸台203通常用于与相邻的换热板20进行定位装配。在换热板20上未设置凸台203的另一面、与凸台203相同位置处还设置有凹槽。在换热板20装配过程中，将第一换热板的凸台203嵌入与第一换热板相邻的第二换热板的凹槽内。通常，该凹槽的深度可以为三分之一至二分之一的基板厚度，使得第一换热板的凸台203与第二换热板的凸台203相互顶住，而凸台203未进行嵌入的部分的高度与凸包2011向外突出的高度相同。因此，优选的，凸台203向外突出的高度可以为凸包2011向外突出的高度与凹槽深度之和。
在本实施例的一些可选的实现方式中，凸包2011的厚度由边缘向中间逐渐增厚。在该可选的实现方式下，凸包2011向基板21的正投影为如图6所示的形状。从图6中可以看出，凸包2011向基板21的正投影所形成的图案为两个相同形状的嵌套。
以椭圆形凸包为例，结合图7，对如图6所示的投影形状的凸包2011的结构进行具体说明。图7示出了椭圆形凸包的结构示意图。椭圆形凸包包括第一表面a1和第二表面a2，其中第一表面a1与基板21的第一表面S1贴合，第二表面a2为凸起的表面。第一表面a1和第二表面a2的边界均是由大小不同、形状相同或相似的椭圆围合而成。也即第一表面与第二表面具有相同的形状。从图6和图7中可以看出，椭圆形凸包由底部向顶部逐渐凸起，使得椭圆形凸包的剖视图为梯形形状。也即是说，a1面和a2面向基板21的正投影为相似的椭圆，并且该两个椭圆具有相同的轴心，并且，a1面椭圆的长轴大于a2面椭圆的长轴。通过将凸包设 置为此种形状，可以减小气流流动阻力，提高流体换热速度。
长条形凸包和水滴形凸包的结构与椭圆形凸包的结构相类似，不同的是围合成第一表面和第二表面的边界的形状不同。在此不再赘述。
继续参考图8，其示出了本申请实施例提供的又一个换热板的表面结构示意图。
在图8中，换热板20包括基板21和在基板21上形成的导流体201。
基板21包括沿第一方向x的第一边B1、第二边B2和沿第二方向y的第三边B3、第四边B4。其中，第一方向x为水平方向，第二方向y为竖直方向。基板20还包括第一表面和与第一表面相对设置的第二表面。
导流体201包括第三凸包2013。图中示意性的示出了导流体201包括沿第二方向y的一列第三凸包2013。该第三凸包2013包括凸包20131、凸包20132，该两个凸包相互分离，如图9a所示，图9a为第三凸包2013的放大示意图。其中，凸包20131沿第三方向m延伸，凸包20132沿第四方向l延伸。其中，沿第三方向m的延长线、沿第四方向l的延长线与沿第一方向x的延长线两两相交。此时，沿第二方向y排布的一列凸包20131可以形成导流体组，沿第二方向y排布的一列凸包20132可以形成导流体组。
凸包20131和凸包20132可以具有相同或不同的形状。优选的，凸包20131和凸包20132向基板21的正投影可以为如图9a所示的细长条状。凸包20131和凸包20132分别包括两端，其中一端靠近基板21的第一边B1，另一端靠近基板21的第二边B2。从图8、图9a中可以看出，凸包20131和凸包20132之间形成“八”字形，也即在靠近基板21的第一边B1的一侧，凸包20131和凸包20132的两端相互靠近，在靠近基板21的第二边B2的一侧，凸包20131和凸包20132的两端相互远离。
本实施例中，气流从换热板20的第二边B2流向第一边B1。当气流通过第三凸包2013时，由于，凸包20131和凸包20132的两端在靠近第二边B2的位置(也即图8所示的两凸包的底端)是分离的，气流可以更容易的从底端流入。而凸包20131和凸包20132的两端在靠近第一边B1的位置(也即图8所示的两凸包的顶端)是靠近的，此时气流在通过该位置时，由于开口较小，使得气流在该位置处形成涡流，也即增大气流与换热板之间的接触面积。这样一来，可以使得气流与换热板之间进行充分换热，提高气流交换效果。
在一些可能的实现方式中，凸包20131和凸包20132由靠近如图8所示的第二边B2的位置至远离该第二边B2的位置，凸包20131和凸包20132的厚度逐渐增大；即凸包20131沿m方向的剖面图和/或凸包20132沿l方向的的剖视图呈现如图9b所示的形状。在图9b中，f’为凸包20131和凸包20132靠近第二边B2的位置，f为凸包20131和凸包20132远离第二边B2的位置。通过将凸包设置不同的厚度，可以降低气流在如图8所示的凸包20131和凸包20132的流动阻力，提高流体速度。
在本实施例中，换热板21包括沿第一方向x和沿第二方向y间隔排列的多个第三凸包2013。也即是说，多个第三凸包2013在基板21上形成第三凸包阵列。
这里需要说明的是，对于同一列中的第三凸包2013，凸包20131和凸包20132关于同一对称轴对称。示例性的，对于图8中的左起第一列第三凸包2013，凸包20131和凸包20132对称的分布在图8所示的对称轴L的两边。这样一来，可以使得气流沿着同一方向流动，避免气流沿多个方向流动导致气流在流道内以及各第三凸包2013之间分布不均，从而提高气流分布的均匀性，可以进一步提高换热效果。
在本实施例的一些可选的实现方式中，第三凸包2013所包括的凸包20131和凸包20132 还可以为如图10所示的形状。图10示出了本申请实施例提供的又一个换热板的表面结构示意图。在图10中，导流体201沿第一方向x间隔排布，导流体201包括沿第二方向y间隔排列的多个第三凸包2013。与图8所示的换热板不同的是，图10所示的换热板20的凸包20131和凸包20132向基板21的投影形成的图案可以为椭圆、水滴等。图10示意性的示出了为椭圆的情形。在一些实现方式中，凸包20131和凸包20132由边缘向中间逐渐凸起，也即为图6、图7所示的凸包的形状。
通过将第三凸包设置成如图6、图10所示的形状，在保障换热效率的条件下，可以降低流体阻力，提高流体速度。
在本实施例中，换热板20可以为金属材料一体成型，也可以为非金属材料一体成型。
从图8、图10所示的换热板20中可以看出，图8所示的凸包20131为细条状，与图10所示的凸包20131相比，其沿第三方向m的长度大于图10所示的凸包20131的长度。因此，与图10所示的换热板20中的凸包的形状相比，图8所示的换热板20中的凸包排列更加紧密、牢固，具有更强的承受力度。因此，在一些实现方式中，当换热板20为金属材料时，由于金属材料具有较高的硬度，此时可以采用如图10所示凸包结构形成换热板。在如图10所示换热板中，导流体201可以形成于同一面，例如形成于第一面S1；导流体201也可以形成于不同面。此时，导流体201间隔形成于不同面。具体来说，沿图10所示的从左向右方向，第一列的第三凸包2013形成于第一面，第二列的第三凸包2013形成于第二面，第三列的第三凸包2013形成于第一面…，依次类推，从而可以减少换热器中换热板的数目，节约成本。
在一些实现方式中，当换热板20为非金属材料时，由于形成非金属材料的高分子材料硬度较低，此时可以采用如图8所示的凸包结构形成换热板。此时，导流体201可以形成于同一面，以提高换热板的承受力度。
在一些可能的实现方式中，导流体201可以包括图8所示的第三凸包2013和图10所示的第三凸包2013的组合，如图11所示。图11示出了本申请实施例提供的换热板的又一个表面结构示意图。在图11所示的导流体201中，图8所示的形状的第三凸包2013和图10所示的形状的第三凸包2013交错排布。此时，图8所示的凸包20131和图10所示的凸包20131沿第二方向y形成导流体组，图8所示的凸包20132和图10所示的凸包20132沿第二方向y形成导流体组。从图11中可以看出，导流体组可以成对的轴对称分布。通过采用此结构制造换热板，可以兼顾换热板的换热效率和支撑力度。此结构的换热板既适用于金属材料制造，也适用于非金属材料制造，可以根据应用场景的需要选择。举例来说，当气体流量较小、但需要交换的能量较高时，可以采用此结构。
在一些可能的实现方式中，换热板20包括如图8、图10、图11任意一图所示的导流体201以及支撑结构202的组合，如图12所示，图12示出了图11所示的导流体201与支撑结构202的组合形成的换热板的表面结构示意图。其中，支撑结构202可以与图2所示的支撑结构202具有相同的结构，在此不再赘述。这样一来，可以将气流进一步的限制在两个支撑结构202形成的腔体内，使得气流的分布更加均匀。同时，通过设置支撑结构202，还可以使得换热板20更加稳固。
在一些可能的实现方式中，如图12所示的支撑结构202上还可以设置有凸包2021，如图13所示，凸包2021的形状可以为图6所示的任意一种。通过在支撑结构202上设置凸包2021，可以进一步提高换热效率。
请继续参考图14，其示出了本申请实施例提供的又一个换热板的表面结构示意图。
在图14中，换热板20包括基板21和在基板21上形成的多个导流体。
基板21包括沿第一方向x的第一边B1、第二边B2和沿第二方向y的第三边B3、第四边B4。其中，第一方向x为水平方向，第二方向y为竖直方向。基板20还包括第一表面S1和第一表面S1相对设置的第二表面。
多个导流体包括导流体201。导流体201包括第四凸包2014和第五凸包2015。其中，第四凸包2014沿第二方向y延伸，第五凸包2015沿第三方向z延伸。这里，第三方向z的延长线与第二方向y的延长线交叉。具体的，第三方向z与第二方向y之间的夹角范围为[-15°，-75°]。第四凸包2014与第五凸包2015向基板21的正投影形成的图案可以为椭圆、水滴、长条等。
在一些实施方式中，第四凸包2014和第五凸包2015向基板21的正投影所形成的图案还可以如图6所示，具体结构可参考图6对应的相关描述，在此不再赘述。
请继续参考图14，在图14中，沿第一方向x，相邻的两个凸包具有不同的延伸方向。以图14中第一行凸包举例来说，从左向右，分别为第四凸包2014、第五凸包2015、第四凸包2014…，也即是说，每一个凸包和其相邻的凸包的延伸方向均不相同。从而，当气流从凸包的各间隙之间流过时形成涡流，增大气流与换热板之间的接触面积，提高换热效率。
进一步的，以左边第一个导流体201为起始，每两个导流体作为一组，该组导流体与相邻组导流体之间具有较大的距离间隔，从而形成气流通道。也即在图15中，第二个第一导流体和第三个第一导流体之间形成流道。这样一来，可以减小气流在换热板流道内流动时的阻力，提高气流流动速度。
基于上述各实施例所示的换热板，本申请实施例还提供了一种换热器。具体的，请参考图15，图15示出了换热器1500的结构示意图。换热器1500包括对换热器进行结构支撑的支撑件1502、用于保护换热板的挡板1501以及多个层叠的换热板1503。从图15中可以看出支撑件1502共四根，分布于换热器1500的四周，对换热器1500进行支撑、并形成容纳换热板1503的空间。挡板1501相对设置、设置在换热器1500的相对的两个表面。通过设置支撑件1502以及挡板1501，可以对换热板进行的支撑和保护。
图15所示的多个换热板1503可以为以上任意实施例所示的换热板。
下面以如图5所示的换热板为例，结合图16、图17(a)-图17(c)、图18(a)-图18(c)，对换热板的装配方式进行详细说明。为了更加清楚的对包括本申请所示的换热板的装配方式进行说明，图16示意性的示出了2个相邻的换热板。可以理解的是，本申请并不对换热器所包括的换热板的数目进行限制，根据应用场景的需要而设定。
如图16所示，换热板161的表面结构示意图与图5所示的换热板20表面结构示意图相同，换热板162的表面结构示意图与换热板161的表面结构示意图相比，向右旋转90度。在换热器具体的安装过程中，换热板161的定位凸台1611、1612、1613、1614、1615、1616分别与换热板162的定位凸台1621、1622、1623、1624、1625、1626一一对应安装。在图16中，换热板161中的第一导流体包括多个凸包1618，第二导流体包括支撑凸包1617；换热板162中的第一导流体包括多个凸包1628，第二导流体包括支撑凸包1627。
当换热板中的第一导流体和第二导流体位于同一面、朝同一方向凸起时，换热板161、换热板162的剖视图分别如图17(a)、17(b)所示。具体的，图17(a)为沿图16所 示的换热板161中的bb’位置处的剖视图，图17(b)为沿图16所示的换热板162中的cc’位置处的剖视图。在图17(a)中，换热板161的第一面S1设置凸台1614、1615、1616，在换热板161的第二面S2、与凸台1614、1615、1616相同位置处设置有凹槽1619。在图17(b)中，换热板162的第一面S3设置有凸台1624、1625、1626，在换热板162的第二面S4、与凸台1624、1625、1626相同位置处设置有凹槽1629，上述凹槽1619、凹槽1629的深度小于基板的厚度。可选的，该凹槽的深度可以为三分之一至二分之一基板的厚度。在换热板装配过程中，设置于换热板161的第一面S1的凸台1614、1615、1616分别嵌入换热板162的第二面S4的凹槽1629处。如图17(c)所示，图17(c)示出了本申请实施例提供的两换热板之间的装配示意图。上述各凸台向外凸起的高度通常为凹槽的深度与凸包1618向外凸起的高度之和。这里，凸包1618和支撑凸包1617可以具有相同的高度，从而使得当凸台1614、1615、1616分别嵌入凹槽1629之后，换热板161中的凸包1618、支撑凸包1617突出的表面恰好顶住换热板162的背面，形成多个空气流道，将气流均匀的限制在流道内，使得气流在流道内的分布更加均匀。同时，还可以使得换热板之间相互支撑，提高换热板的稳定性以及牢固性。这里需要说明的是，换热板161中的其他凸台均以如上所述的嵌入方式嵌入至换热板162第二面S4中的凹槽中。可以理解的是，图15所示的换热器1500中每相邻的两个换热板均可以通过如图17(c)所示的装配方式进行装配。
当换热板中的第一导流体和第二导流体位于不同面时，换热板161、换热板162的剖视图分别如图18(a)、18(b)所示。具体的，图18(a)为沿图16所示的换热板161中的bb’位置处的剖视图，图18(b)为沿图16所示的换热板162中的cc’位置处的剖视图。其中，凸包1618位于换热板161的第一面S1，支撑凸包1617位于换热板161的第二面S2；凸包1628位于换热板162的第一面S3，支撑凸包1627位于换热板162的第二面S4。当换热板161、换热板162的剖视图分别为如图18(a)、18(b)所示时，换热板161与换热板162之间的装配方式与图17(a)、图17(b)所示的剖视图之间的装配方式相同，具体描述可以参考图17(a)、图17(b)的相关描述，在此不再赘述，换热板161与换热板162叠装后的剖视图如图18(c)所示。这里需要说明的是，上述各凸台向外凸起的高度通常为凹槽的深度、支撑凸包1617(或1627)向外凸起的高度、凸包1618(或1628)向外凸起的高度之和。从而使得当凸台1614、1615、1616分别嵌入凹槽1629之后，位于换热板161第一面S1的凸包1618正好与位于换热板162第二面S4的支撑凸包1627突出的表面互相顶住，形成多个空气流道，将气流均匀的限制在流道内，使得气流在流道内的分布更加均匀。同时，还可以使得换热板之间相互支撑，提高换热板的稳定性以及牢固性。可以理解的是，图15所示的换热器1500中每相邻的两个换热板均可以通过如图18(c)所示的装配方式进行装配。
这里需要说明的是，当换热板上没有设置凸台时，可以利用换热板中的凸包之间互顶的力进行装配。此方法为现有的换热板惯常的装配方式，在此不在赘述。
在图15中，换热器1500包括由多个换热板1503堆叠而成的第一面T1、与第一面T1相对的第二面T2。第三面T3和与第三面相对的第四面T4。其中，第二面T2和第四面T4未示出。第一面T1所在侧为冷空气进风口，第二面T2所在侧为冷空气换热成热空气的出风口，第三面T3所在侧为热空气进风口，第四面T4所在侧为热空气换热冷却后的空气出风口。其中，图16所示的换热板161的边B1、换热板162的边B1位于第一面T1侧；换 热板162的边B2、换热板162的边B2位于第二面T2侧；换热板161的边B3、换热板162的边B3位于第三面T3侧；换热板161的边B4、换热板162的边B4位于第四面T4侧。
当采用图17(c)所示的两换热板之间装配方式形成图15所示的换热器1500时，结合图15、图16、图17(a)-图17(d)，对换热器1500的换热原理进行说明。其中，图17(d)示出了4个换热板层叠的结构示意图。其中，换热板d1、换热板d3的结构和装配方向可以与图16、图17(b)、图17(c)中的换热板162相同，换热板d2、d4的结构和装配方向可以与图16、图17(a)、图17(c)中的换热板161相同。
外部冷空气从第一面T1进入换热器1500，也即从图17(d)所示的换热板d1与d2之间形成的空气流道n、d3与d4之间形成的空气流道n进入换热器1500。在换热器1500内部，外部冷空气与换热板d1、d2、d3、d4进行接触换热、与空气流道内的空气进行气流换热后，转换成热空气从换热器1500的第二面T2输出。数据中心中的设备产生的热空气从第三面T3进入换热器1500，也即从图17(d)所示的换热板d1与其上层的换热板(图中未示出)之间形成的空气流道、换热板d2与换热板d3之间形成的空气流道进入换热器1500(由于该空气流道在图17(d)中被支撑凸包挡住，图中未示出该空气流道)。在换热器1500内部，热空气与换热板d1、d2、d3进行接触换热、与空气流道内的空气进行气流换热后，转换成冷却后的空气，也即是数据中心所需要的新风，从换热器1500的第四面T4输出。由此，换热器1500实现热空气与冷空气的交换，达到降低数据中心的空气温度的目的。也即是说，外部冷空气和数据中心的设备产生的热空气的空气流道分别设置于不同层，外部冷空气和数据中心的设备产生的热空气分别通过不同层的空气流道进入换热器1500内部，与换热板和空气流道内的空气进行换热后流出。
当采用图18(c)所示的两换热板之间装配方式形成图15所示的换热器1500时，结合图15、图16、图18(a)-图18(d)，对换热器1500的换热原理进行说明。其中，图18(d)示出了4个换热板层叠的结构示意图。其中，换热板d1、换热板d3的结构和装配方向可以与图16、图18(b)、图18(c)中的换热板162相同，换热板d2、d4的结构和装配方向可以与图16、图18(a)、图18(c)中的换热板161相同。
外部冷空气从第一面T1进入换热器1500，也即从图18(d)所示的换热板d1与换热板d2之间形成的空气流道n、换热板d2与换热板d3之间形成的空气流道n、换热板d3与换热板d4之间形成的空气流道n进入换热器1500。在换热器1500内部，外部冷空气与换热板d1、d2、d3、d4进行接触换热、与空气流道内的空气进行气流换热后，转换成热空气从换热器1500的第二面T2输出。数据中心中的设备产生的热空气从第三面T3进入换热器1500，也即从图18(d)所示的换热板d1与换热板d2之间形成的空气流道、换热板d2与换热板d3之间形成的空气流道、换热板d3与换热板d4之间形成的空气流道进入换热器1500(图18(d)中未示出热空气的空气流道)。在换热器1500内部，热空气与换热板d1、d2、d3、d4进行接触换热、与空气流道内的空气进行气流换热后，转换成冷却后的空气，也即是数据中心所需要的新风，从换热器1500的第四面T4输出。由此，换热器1500实现热空气与冷空气的交换，达到降低数据中心的空气温度的目的。也即是说，外部冷空气和数据中心的设备产生的热空气的空气流道可以设置于同一层，外部冷空气和数据中心的设备产生的热空气可以利用同一层的空气流道进入换热器1500内部，与换热板和空气流道内的空气进行换热后流出。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方 式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
