现有的换热器普遍需要依据实际使用时的热交换情况进行定制。这导致换热器的生产效率低、制造成本高、生产周期长。
为此，下面的实施例提供一种换热单元，这样的换热单元能够彼此插接形成大型的换热矩阵，其扩展性强。用户能够根据实际需要，选用任意数量的换热单元构成大型的换热矩阵。进而在生产中，无需按用户需求定制，只需要生产标准化的换热单元即可，提高了生产效率、降低了制造成本和生产周期。
实施例：
请参照图1，图1为本发明实施例提供的换热单元10的立体结构示意图。换热单元10包括为长方体结构的机身壳体110。在机身壳体110内部设置有换热器。在本实施例中，换热器为管壳式换热器200(管壳式换热器200在图2和图3中示出)。
请参照图2，图2示出了管壳式换热器200的内部结构。管壳式换热器200包括管壳式换热器壳体210以及若干个设置在管壳式换热器壳体210内的换热管220。换热管220的两端贯穿管壳式换热器壳体210并暴露在管壳式换热器壳体210外。换热管220构成管壳式换热器200的管程。在本实施例中，管壳式换热器200的管程为高温能量媒介通道221。换热管220的两端分别构成高温能量媒介通道221的进口和出口。管壳式换热器壳体210与换热管220之间的空间构成管壳式换热器200的壳程。在本实施例中，管壳式换热器200的壳程为低温能量媒介通道211。在管壳式换热器壳体210上开设有第一通孔212和第二通孔213。第一通孔212作为低温能量媒介通道211的进口，第二通孔213作为低温能量媒介通道211的出口。这样，高温能量媒介通过高温能量媒介通道221的进口进入高温能量媒介通道221，低温能量媒介通过第一通孔212进入低温能量媒介通道211。高温能量媒介和低温能量媒介在管壳式换热器200中进行热交换。然后，高温能量媒介通过高温能量媒介通道221的出口导出，低温能量媒介通过第二通孔213导出。在本实施例中：高温能量媒介为高温流体，具体为高温液体或高温气体；低温能量媒介为低温流体，具体为低温液体或低温气体。所谓“高温”和“低温”是相对而言的，即将两种能量媒介的温度进行比较，温度高的为高温能量媒介，温度低的为低温能量媒介。
图1所示的换热单元10，其机身壳体110的四个外表面为组合 面，分别为上组合面120、左组合面130、下组合面140和右组合面150。在上组合面120、左组合面130、下组合面140和右组合面150上分别设置有一组接口群。以图1上能够看见的上组合面120和右组合面150为例：在上组合面120上设有四个接口，四个接口分别为高温能量媒介入口121、高温能量媒介出口122、低温能量媒介入口123、低温能量媒介出口124；在右组合面150上设有四个接口，四个接口分别为高温能量媒介入口151、高温能量媒介出口152、低温能量媒介入口153、低温能量媒介出口154。事实上，在与上组合面120相对的下组合面140上设有与上组合面120上的四个接口相同的四个接口，下组合面140上的四个接口的位置与上组合面120上的四个接口的位置镜像对称；在与右组合面150相对的左组合面130(图1中的背面)上设有与右组合面150上的四个接口相同的四个接口，右组合面150上的四个接口的位置与左组合面130上的四个接口的位置镜像对称。这种上下左右相对称的设计，使得当两个换热单元10上下组合或左右组合时，传输同种能量媒介的接口相互正对并连接成一个整体。
请参照图3，图3为本发明实施例提供的换热单元10的装配爆炸示意图。在图3中，机身壳体110的三个面被拆下，以露出能量媒介管道系统。
能量媒介管道系统包括高温能量媒介进入管310、高温能量媒介排出管320、低温能量媒介进入管330、低温能量媒介排出管340。
高温能量媒介进入管310、高温能量媒介排出管320、低温能量媒介进入管330、低温能量媒介排出管340由设置在管壳式换热器壳体210外表面上的多个凸起301形成。在机身壳体110装配完成 后，凸起301与机身壳体110的内表面密封配合，从而使得能量媒介管道系统与机身壳体110形成一个整体。
高温能量媒介进入管310整体为环状的管道，其与高温能量媒介入口121、151对应，同时也与左组合面130和下组合面140上相应的接口对应。高温能量媒介进入管310将高温能量媒介入口121、151以及左组合面130和下组合面140上相应的接口连通。同时，高温能量媒介进入管310还与管壳式换热器200的高温能量媒介通道221的进口连通。如此，使得换热单元10上的组合面均可同时或分别为管壳式换热器200引入高温能量媒介。
高温能量媒介排出管320整体为环状的管道，其与高温能量媒介出口122、152对应，同时也与左组合面130和下组合面140上相应的接口对应。高温能量媒介排出管320将高温能量媒介出口122、152以及左组合面130和下组合面140上相应的接口连通。同时，高温能量媒介排出管320还与管壳式换热器200的高温能量媒介通道221的出口连通。如此，使得换热单元10上的组合面均可同时或分别为管壳式换热器200引出高温能量媒介。
低温能量媒介进入管330整体为环状的管道，低温能量媒介入口123、153对应，同时也与左组合面130和下组合面140上相应的接口对应。低温能量媒介进入管330将低温能量媒介入口123、153以及左组合面130和下组合面140上相应的接口连通。同时低温能量媒介进入管330还与低温能量媒介通道211的进口(第一通孔212)连通。如此，使得换热单元10上的组合面均可同时或分别为管壳式换热器200引入低温能量媒介。
低温能量媒介排出管340整体为环状的管道，低温能量媒介出 口124、154对应，同时也与左组合面130和下组合面140上相应的接口对应。低温能量媒介排出管340将低温能量媒介出口124、154以及左组合面130和下组合面140上相应的接口连通。同时低温能量媒介排出管340还与低温能量媒介通道211的出口(第二通孔213)连通。如此，使得换热单元10上的组合面均可同时或分别为管壳式换热器200引出低温能量媒介。
如此，能量媒介管道系统将不同接口群里传输同种能量媒介的接口相互连通，使得换热单元通过任何一个接口群均可同时或分别引入引出能量媒介。在本实施例中，通过能量媒介管道系统使得换热单元10从任何一个组合面均可同时或分别引入引出能量媒介。
请参照图4，图4为接口群中接口的结构示意图。接口为流体接口，接口包括插头440和插座410。插座410为筒状，在机身壳体110上开孔，插座410固定在机身壳体110上开设的孔中，使得机身壳体110内部空间和机身壳体110外部的空间相互连通。插座410的内表面设置有固定凸起411。二通接头420的两端为插头440，插头440的端部设置有倒钩441。倒钩441插入并通过固定凸起411卡合在插座410的内壁，形成自锁结构。在插座410和插头440之间垫设有O型密封圈430，用于达到密封的目的。
请参照图5，图5示出了两个换热单元10对应的接口相互连接时的状态。二通接头420两端的插头440分别卡合在两个插座410中，从而将两个换热单元10相应的接口连接。
请参照图6，图6示出了换热单元10的接口需要封闭时的状态。截止接头450的一端为插头440，其另一端封闭。如此插头440卡合在插座410中，如此形成封闭的接口。在接口不需要与其他换热 单元相连时，通过截止接头450对其进行封闭。
在需要将两个换热单元10相应的接口相互连接时，采用二通接头420，在需要将换热单元10上的接口封闭时，使用截止接头450。
参照图7，本实施例提供的换热单元10能够构成换热矩阵20。在图7中，六个换热单元10以3×2的方式叠加组合在一起形成换热矩阵20。六个换热单元10各自相邻组合面紧密贴合，其上的传输同种能量媒介的接口彼此插接，例如：各个换热单元10的高温能量媒介入口与相邻换热单元10的高温能量媒介入口连接在一起，从热源供给的高温能量媒介通过其中一个换热单元10的高温能量媒介入口接入，然后进入每个换热单元10，为换热单元10的高温能量媒介通道221提供高温能量媒介。同理，从每个换热单元10的高温能量媒介通道221的出口流出的高温能量媒介通过其中一个换热单元10的高温能量媒介出口导出。低温能量媒介通过其中一个换热单元10的低温能量媒介入口接入，然后进入每个换热单元10，为换热单元10的低温能量媒介通道211提供低温能量媒介。同理，从每个换热单元10的低温能量媒介通道211的出口流出的低温能量媒介通过其中一个换热单元10的低温能量媒介出口导出。
如此，构成换热矩阵20的第i个换热单元10的换热功率为Pi，则换热矩阵20的换热功率P＝∑Pi。通过换热单元10的矩阵式组合，实现了换热功率的扩展。其中，i为大于等于1的正整数。
采用本实施例提供的换热单元10，用户能够根据实际需要，选用任意数量的换热单元10构成大型的换热矩阵20。进而在生产中，无需按用户需求定制，只需要生产标准化的换热单元10即可，提高了生产效率、降低了制造成本和生产周期。
需要说明的是，在本实施例中，换热单元10为长方体结构，其主要目的在于便于换热单元10之间的紧密连接，从而提高空间使用率。在其他具体的实施方式中，换热单元10的形状不限于长方体。
还需要说明的是，换热单元10的至少两个接口群可以设置在换热单元10的同一面上。在本实施例中，之所以将接口群分别设置在不同的组合面上，是为了便于相邻换热单元10之间的相互插接。
还需要说明的是，在本实施例中，换热单元10具备四个组合面，组合面的数量为偶数个。在其他具体实施方式中，组合面的数量也可以为奇数个。同时，本实施例中，长方体结构的换热单元10的六个面都可以构成组合面。
在本实施例中，换热单元10的换热器为管壳式换热器200。可以理解的，板式换热器也能够作为换热单元10的换热器。
以上所述仅为本发明的部分实施例而已，并不用于限制本发明，对于本领域技术人员来说，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。
