在该实施例中，高表面能材料利用自身的亲水性实现冷凝水的分布控制和流量控制，具体地，表面能高的区域的亲水(导水)能力强于表面能较低的区域的亲水(导水)能力，冷凝水依靠自身表面张力和分子间的作用力沿着接水盘底部接受高表面能材料的疏导。这些高表面能材料以涂布的工艺进行设置，涂层厚度为1×10-3毫米至1毫米。在冷凝水需求量大的位置使用较高表面能的材料，在冷凝水需求量小的位置使用较低表面能的材料，其中，高表面能材料的表面能足以支持介质层使其具有亲水能力，之后不同位置的表面能只需要具有相对的高低区分即可，不必得知表面能的具体数值。另外，在不需要冷凝水流经的位置也可以设置憎水(疏水)材料用以帮助形成导水路线。

在该实施例中，接水盘上设置有多个出水口，每个出水口都做特殊处理，即出水侧穿过接水盘底部的上表面，在出水侧设置有内倒角，便于设置介质层并增加出水口的排水量；蓄水侧设置有出水口凸台，出水口凸台用于保证水层高度，此水层高度的存在可以使多个出水口同时开始排水，用以更好地支持介质层的导水功能。整体上来看，多个出水口可根据具体使用情况进行设置，内倒角和出水口凸台的设置则可以改善介质层的工作环境。

在该实施例中，多孔材料作为介质层进行设置的情况下，其本身也会吸收一部分冷凝水，所以，其厚度根据冷凝水发生量进行调整，此外，如果装配间隙较大，需要发挥介质层改善部件之间的接触的效果时，可以设置加厚介质层。高表面能材料作为介质层进行设置时，可整体涂布在接水盘底部或局部涂布在内倒角表面及其周围区域，并根据散热部的换热能力或者工作温度设计出对应的表面能梯度(即不同区域的材料表面能不同，与多个散热部的换热能力和温度正相关)。

图3示出了根据本发明的第二方面实施例的空调器的框图。
如图3所示，一种空调器300，包括：如上述第一方面实施例的接水盘200，以及：蒸发器302，用于空调器300的制冷剂的热交换过程并产生冷凝水；冷凝器304，用于空调器300的制冷剂的热交换过程；装配部306，用于接水盘200、蒸发器302、冷凝器304之间的装配。
根据本发明第二方面实施例的空调器300，蒸发器302在换热过程中会产生冷凝水，而冷凝器304在换热过程中需要冷却水，所以通过装配部 306将本发明第一方面实施例中提供的接水盘200安装在此空调器300系统中，实现冷凝水的回收利用，可以提高空调器300性能。再利用接水盘200的介质层204的特殊设置，实现冷凝水的合理分配，还能够进一步提高空调器300性能。其中，所述接水盘200的介质层204能够调整冷凝水的分布和其在局部位置的流量。使冷凝水的冷却作用更好地被利用。
根据本发明第二方面的实施例的空调器300，优选地，还包括：打水电机308，用于将冷凝水输送至接水盘200。
在该实施例中，打水电机308可以帮助输送冷凝水至接水盘200，也能够从另外的水源汲水用以补充接水盘200的水量。
根据本发明第二方面的实施例的空调器300，优选地，冷凝器304中包括多根散热管。
在该实施例中，冷凝器304由多根散热管构成，方便制冷剂的放热过程。
根据本发明第二方面的实施例的空调器300，优选地，接水盘200的多个出水口206对应于冷凝器304的多根散热管进行设置。
在该实施例中，多个出水口206对应于多个散热管进行设置，可以更好地发挥冷凝水或其它液体的传热效果。同时，也方便厂家或者用户根据不同散热管的换热能力为其对应位置上的接水盘200涂布具有不同表面能的多种高表面能材料。
根据本发明第二方面的实施例的空调器300，优选地，介质层204材料为多种高表面能材料时，根据多个换热管的换热系数进行多种高表面能材料的涂布布局；介质层204不同位置的表面能与对应的换热管的换热系数正相关。
在该实施例中，换热能力强的散热管需要较多的冷凝水进行冷却，那么就在其对应位置的接水盘200底部涂布亲水能力更强的高表面能材料，使其相对于其它散热管能够获得更多的冷却水。可以在冷凝水不足的情况下尽量使冷凝水去冷却那些换热能力强(或者说是温度较高)的散热管。
图4示出了根据本发明的第三方面实施例的改变冷凝水分布的方法的流程图。
如图4所示，根据本发明第三方面的实施例，还提出了一种改变冷凝 水分布的方法，包括：步骤402，在待冷却装置与接水盘之间设置高表面能材料和/或多孔材料，形成介质层；其中，所述高表面能材料具有多个表面能梯度，通过计算所述待冷却装置的各个散热部的换热能力，得到相应的计算结果，并根据所述计算结果选择多种高表面能材料进行设置，所述高表面能材料的表面能与所述散热部的换热能力正相关。或者通过实验或实测的方法确定不同散热部的工作温度，在温度较高的散热部上方的接水盘主体对应位置设置表面能较高的高表面能材料作为介质层。
根据本发明第三方面的实施例的改变冷凝水分布的方法，步骤402在待冷却装置上设置接水盘，在二者之间进一步设置介质层。所述介质层由具有多个表面能梯度的高表面能材料制成，此时，能够利用高表面能材料的特性控制冷凝水的分布及局部的流量，具体地，涂布有高表面能材料的位置能够导水，用以改变冷凝水的分布位置，材料表面能相对较高的位置则具有更大的流量。当所述介质层由多孔材料制成时，多孔材料能够利用本身材料特性防止冷凝水在接水盘底部某一位置聚集，使冷凝水均匀分布，实现均匀排放。
根据本发明第三方面的实施例的改变冷凝水分布的方法的步骤402，优选地，接水盘上设置有多个出水口，用于排放冷凝水；其中，出水口具有出水侧和蓄水侧，出水侧穿过接水盘底部的上表面，在出水侧设置有内倒角，蓄水侧设置有出水口凸台，出水口凸台用于保证水层高度，使多个出水口同时开始排水，内倒角便于设置介质层并增加出水口的排水量。
在该实施例中，接水盘上设置有多个出水口，每个出水口都做特殊处理，即出水侧穿过接水盘底部的上表面，在出水侧设置有内倒角，便于设置介质层并增加出水口的排水量；蓄水侧设置有出水口凸台，出水口凸台用于保证水层高度，此水层高度的存在可以使多个出水口同时开始排水，用以更好地支持介质层的导水功能。整体上来看，多个出水口可根据具体使用情况进行设置，内倒角和出水口凸台的设置则可以改善介质层的工作环境。
根据本发明第三方面的实施例的改变冷凝水分布的方法的步骤402，优选地，内倒角的角度根据出水口的高度、直径以及接水盘底部的厚度进行设置，出水口凸台高度根据冷凝水的发生量进行设置。
在该实施例中，综合考虑使用环境、接水盘厚度以及出水口高度等因 素进行内倒角的设计，可以更好地发挥其便于设置介质层并增加出水口的排水量的作用，出水口凸台高度则根据冷凝水发生量进行设计，防止过多的冷凝水聚集在凸台周围而不能被利用。
根据本发明第三方面的实施例的改变冷凝水分布的方法的步骤402，优选地，多个出水口对应于多个散热部进行设置。
在该实施例中，为了取得更好的冷却效果，用于排水降温的出水口应对应于待冷却装置的多个散热部进行安装，例如，散热部是一根一根的散热管，那么就按照一个出水口对应一根散热管的方式进行布局。
根据本发明第三方面的实施例的改变冷凝水分布的方法的步骤402，优选地，多孔材料的材质和厚度根据装配间隙和冷凝水发生量进行选择，能够设置在接水盘侧，也能够设置为独立部件，高表面能材料以涂布的形式进行设置；多种高表面能材料设置在多个出水口内倒角表面和/或接水盘出水侧。
在该实施例中，多孔材料作为介质层进行设置的情况下，其本身也会吸收一部分冷凝水，所以，其厚度根据冷凝水发生量进行调整，此外，如果装配间隙较大，需要发挥介质层改善部件之间的接触的效果时，可以设置加厚介质层。高表面能材料作为介质层进行设置时，可整体涂布在接水盘底部或局部涂布在内倒角表面及其周围区域，并根据散热部的换热能力或者工作温度设计出对应的表面能梯度(即不同区域的材料表面能不同，与多个散热部的换热能力和温度正相关)。
图5示出了根据本发明实施例的介质层设置示意图。
如图5所示，冷凝器502上部安装有接水盘510，标号508处按照3：1的比例放大后，如左侧圆内所示，接水盘510上设置有出水口506，在出水口506(接水盘510)下部设置高表面能材料涂层504。
在该实施例中，蒸发器(图中未示出)在换热过程中会产生冷凝水，而冷凝器502在换热过程中需要冷却水，所以将本发明第一方面实施例中提供的接水盘510安装在此冷凝器502上，实现冷凝水的回收利用。再利用接水盘510下部设置的高表面能材料涂层504实现冷凝水的合理分配，其中，所述接水盘510下方的高表面能材料涂层504能够调整冷凝水的分 布和其在局部位置的流量。使冷凝水的冷却作用更好地被利用。冷凝器502中包括多根散热管，接水盘510上设置的多个出水口506对应于冷凝器502的多根散热管进行设置，可以更好地发挥冷凝水或其它液体的传热效果。同时，也方便厂家或者用户根据不同散热管的换热能力为其对应位置上的接水盘510底部涂布具有不同表面能的高表面能材料涂层504。换热能力强的散热管需要较多的冷凝水进行冷却，那么就在其对应位置的接水盘510底部涂布亲水能力更强的高表面能材料，使其相对于其它散热管能够获得更多的冷却水。可以在冷凝水不足的情况下尽量使冷凝水去冷却那些换热能力强(或者说是温度较高)的散热管。接水盘510采用常规塑料材料，成型后在靠近冷凝器502那一侧喷涂高表面能材料504，比如：TiO2、改性丙烯酸酯树脂等。亲水层厚度0.001-1毫米，进一步地，可采用不同的表面能材料进行布局。
根据图5所示的介质层设置，其中，高表面能材料涂层504也可以由多孔材料代替，多孔材料具备一定的柔性以改善接水盘510与冷凝器502之间的接触。该材料可以为发泡聚氨酯、发泡聚乙烯、发泡PVC/NBR，厚度为0.1-20毫米。该多孔材料可以设置为独立部件，也可以附加安装在冷凝器502上。相比于采用高能表面材料方案，直接增加多孔材料更加简单可行，可以实现冷凝水的均匀分布，但是不能调整冷凝水在不同位置上的分布和流量。
图6示出了根据本发明的实施例的材料表面能与换热系数的关系的示意图。
如图6所示，冷凝器管排606中有多根散热管602，出水口604设置在接水盘上，介质层608由高表面能材料制成时，表面能Φx,y与冷凝器对应位置当量平均换热系数hx,y有如下关系：
Φx,y＝f(hx,y)
Φx,y为表面能，hx,y为冷凝器对应位置当量平均换热系数，
hx,y由以下公式计算：
hx,y＝∑hi/nx,y
nx,y为所述接水盘对应区域下方所述冷凝器的所述散热管602的数量，hi为每根散热管602的换热系数，hi由以下公式计算：
hi＝Qi/AiΔTi
Qi为第i根所述散热管602的换热量，Ai为第i根散热管602换热面积，ΔTi为第i根所述散热管602的换热温差，
涂层表面能Φx,y与该位置换热系数hx,y符合一定的函数关系规律，简单可处理成线性关系
Φx,y＝Khx,y
K为常数可以由实验得出。
以上结合附图详细说明了本发明的技术方案，本发明提供了一种接水盘，一种空调器和一种改变冷凝水分布的方法，在空调器接水盘与冷凝器之间增加高表面能材料或者增加单独多孔介质结构以改善冷凝水分配，还能够控制冷凝水在不同空间位置的流量，达到主动干预冷凝水分配的目的，提升了空调器性能。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
