鉴于此，需要设置一种箱式换热装置，以降低风机的能耗。
发明内容

在本发明的描述中，需要理解的是，术语“上”、“下”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。需要说明的是，当一个组件被认为是“连接”另一个组件，它可以是直接连接到另一个组件或者可能同时存在居中设置的组件。
下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
本发明实施例提供了一种箱式换热装置，通过优化结构，使室内送风口101和室内回风口102均开设于第一侧板11上，在挪动箱体1以使第一侧板11面向房间后，能有效降低房间连接至箱体1上的管道的总长度，降低了房间至箱体1之间的管道所带来的风阻，从而达到降低风机能耗的效果。
请参阅图1至图4，该箱式换热装置包括箱体1，箱体1中安装有换热芯体2；箱体内形成相互分隔的换热通道10和外风通道20，换热通道10是供室内的空气循环流通的通道，外风通道20是供外界新风流经的通道。换热通道10包括贯穿换热芯体2的多个第一通孔，外风通道20包括贯穿换热芯体2的多个第二通孔，多个第一通孔和多个第二通孔交叉排列。外界新风流经第二通孔，能有效带走换热通道10中的气体的热量，以完成换热。
本实施例中，箱体1还包括开设有室外进风口201的第二侧板12和开设有室外出风口202的第三侧板13；第一通孔的一端连通室内送风口101， 另一端连通室内回风口102；第二通孔的一端连通室外进风口201，另一端连通室外出风口202。第三侧板13可垂直于或平行于第二侧板12，本实施例中，第三侧板13与第二侧板12相邻，且第三侧板13垂直于第二侧板12。
值得说明的是，箱式换热装置需要安装有第一管道和第二管道以投入使用。其中，第一管道用于连通室内空间和室内回风口102，第二管道用于连通室内空间和室内送风口101，以使室内空气能在换热通道10中循环流动以进行换热。本实施例中，通过将室内送风口101和室内回风口102均开设于第一侧板11上，使第一管道和第二管道的总长度得到减少，降低了室内空气所受到的管道风阻，从而达到降低风机功耗的目的；此外，因为风阻降低，单位时间内流经第一通孔的气体更多，有效提升了换热芯体2的换热效果。
在另一个具体的实施例中，第二侧板12和第三侧板13均与第一侧板11相邻，且第二侧板12和第三侧板13均垂直于第一侧板11。值得说明的是，此时无论是室外进风口201，还是室外出风口202，其开设的面积均可以设置得更大，以提升外界空气进入外风通道20的风量，从而有效提升换热芯体2的换热效率。此外，还需说明的是，由于室外出风口202和室外进风口201处于不同的侧板上，从室外出风口202排出的外界空气基本上不会再次回到外风通道20中，即进入外风通道20中的空气是温度较低的空气，从而进一步提升了换热芯体2的换热效率。
在另一个具体的实施例中，请参阅图3，箱体1还包括与第二侧板12相对的第四侧板14，且第三侧板13为箱体1的顶板；第四侧板14上也设置有室外进风口201。此时，室外空气从箱体1的两侧进入外风通道20中，然后再从箱体1的顶部排出换热后的外界空气，这进一步增加了室外进风口201的进风量，有利于进一步提升换热芯体2的换热效果。或者，也可在第四侧板14上设置有室外出风口202，提升排风能力，这同样具有提升换热芯体2的换热效果的作用。或者，也可在第四侧板14上同时设置有室外进风口201和室外出风口202，以增大外风通道20的换热风量。
可选地，箱体1还包括与第一侧板11相对的第五侧板15，可根据实 际需求，在第五侧板15上设置有室外出风口202和/或室外出风口202，以增大外风通道20的换热风量，提升箱式换热装置的换热效率。
可选地，第一侧板11上还设置有室外进风口201和/或室外出风口202，能有效节省安装空间，方便在较小的空间内放置下更多的箱式换热装置。
可选地，换热芯体2为并列设置的至少两个菱形芯体21，且相邻两菱形芯体21的顶角相互连接；
菱形芯体21的第一侧包括第一内棱面211和第一外棱面212，菱形芯体21的第二侧包括第二内棱面213和第二外棱面214；
第一内棱面211和第二内棱面213之间开设有第一通孔，第一外棱面212和第二外棱面214之间设有第二通孔。
值得说明的是，所有菱形芯体21可横向并列排布，也可竖向并列排布，或者其他的并列排布方式均可。具体地，相比现有的串联式换热芯体结构，并列设置的菱形芯体21的结构，能有效降低风阻，提高换热效率和减少风机的运行能耗。
可选地，箱体1内设置有用于分隔换热通道10和外风通道20的隔板组件16。
需要说明的是，换热芯体2可包括两个及以上的菱形芯体21；隔板组件16，用于区分出换热通道10和外风通道20。在箱体1中安装有不同数量的菱形芯体21时，需要合理设置隔板组件16的形状、安装位置，以满足区分出换热通道10和外风通道20的目的。
可选地，箱式换热装置还包括补冷装置3，补冷装置3包括均设置于外风通道20中的冷凝器31和喷淋装置，以及设置于换热通道10中的蒸发器32；
冷凝器31设置于换热芯体2和室外出风口202之间，蒸发器32处于换热芯体2和室内送风口101之间；喷淋装置包括喷头331和挡水板332，喷头331安装于冷凝器31和换热芯体2之间，挡水板332设置于喷头331和室外出风口202之间，且室外出风口202和/或室内送风口101中安装有若干个风机。
值得说明的是，补冷装置3还包括分别与蒸发器32和冷凝器31连接的压缩机。在实际运行过程中，在外界环境温度过高导致换热芯体2的换热效率不能达到设计要求时，启动补冷装置3，其中喷淋装置的喷头331向换热芯体2喷水，以冷却换热芯体2，若此时仍不能满足室内降温需要，启动压缩机使蒸发器32冷却换热通道10的室内空气，使流经换热芯体2的室内空气被冷却至设定温度以下。还需说明的是，挡水板332具有干燥吸湿能力；一方面，挡水板332能构成对风机5的防护，以防止蒸发后的高湿水汽随换热气流被带入至室外出风口202中的风机5上，能有效改善室外出风口202中风机5的工作环境，降低室外出风口202中的风机5电子元器件失效的风险，有利于延长风机5的使用寿命；另一方面，挡水板332的设置能改善冷凝器31的工作环境，避免高湿水汽直接冲击冷凝器31上的换热翅片，降低了换热翅片的腐蚀速度，延长了冷凝器31的使用寿命。
可选地，若干个风机5间隔错位布置；相邻的两个风机5之间设置有用于防止串风的分隔板4。
值得说明的是，分隔板4之间分开了相邻的两个风机5，能有效防止相邻的风机5相互串风，利于形成稳定的换热气流。
以上所述，以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
