为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施例。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全 面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1所示，本申请的一种换热器100，包括换热器本体20及用于清洗换热器本体20的清洗装置40。
换热器本体20包括多根平行设置的换热管，多根平行设置的换热管并排设置，使得换热器本体20大体呈扁长方体状。其中，换热器本体20的厚度方向为换热管的径向，换热器本体20的长度方向为换热管的轴向，换热器本体20的宽度方向为换热管的排列方向，换热器本体20垂直于厚度方向的两个相对的端面为待清洗面。
清洗装置40包括驱动结构41、清洗结构43以及导向组件45。清洗结构43传动连接于驱动结构41并限位于导向组件45，驱动结构41可驱动清洗结构43在导向组件45的限位下在换热器本体20的长度方向上往复移动，从而不断清洗换热器本体20的待清洗面。
如图1-图3所示，在一些实施例中，驱动结构41包括驱动组件及传动带414。
其中，驱动组件包括驱动件(图未示)及两个传动轮轴412，两个传动轮轴412间隔设置于换热器本体20的长度方向上的两端，驱动件传动连接于其中一个传动轮轴412以为传动轮轴412提供动力。
传动带414绕设于两个传动轮轴412以形成环绕换热器本体20的环状结构，传动带414包括两段直行段及连接两个直行段两端的弯曲段，两个弯曲段弯曲而分别与两个传动轮轴4123接触，两个直行段沿换热器本体20的长度方向沿直线延伸，且两个直行段平行并间隔设置，清洗结构43固接于直行段(如图4所示)。
如此，驱动件可驱动传动轮轴412转动，转动的传动轮轴412带动传动带414循环移动，最终带动清洗结构43相对换热器本体20不断移动，从而清洗换热器本体20的待清洗面。
具体在一实施例中，驱动结构41包括一组驱动组件及一根与该驱动组件配合的传动 带414。可以理解，在其它实施例中，驱动结构41可包括多组驱动组件及与该多组驱动组件分别配合的多条传动带414，多组驱动组件及传动带414沿换热器本体20的宽度方向间隔设置，从而为清洗结构43提供更大的动力。
具体在一实施例中，驱动件为驱动电机，传动带414可以由链条或者履带形成。可以理解，在其它实施例中，驱动件也可为其它动力源。驱动件的数量可为一个，一个驱动件可驱动一个传动轮轴412也可同时驱动两个传动轮轴412同步转动；驱动件的数量也可为两个，两个驱动件分别驱动两个传动轮轴412同步转动。
请继续参阅图1及图2，清洗结构43包括两组清洗组件，两组清洗组件分别固接于传动带414的两段直行段，每组清洗组件形成一个清洗平面，两个清洗平面相互面对且分别位于换热器本体20相对的两侧，两个清洗平面之间形成用于收容换热器本体20的清洗腔。如此，两个清洗平面分别与换热器本体20的两个待清洗面接触以分别清洗两个待清洗面。
具体在一实施例中，每组清洗组件均包括一个清洗件432，清洗件432包括面向换热器本体20的清洗面，清洗面在驱动结构41的带动下沿换热器本体20的长度方向往复移动而界定形成一个清洗平面，以清洗换热器本体20的待清洗面。也就是说，清洗平面是由清洗面形成的虚拟平面，清洗平面实际上为位于换热器本体20一侧并完全覆盖换热器本体20对应侧的清洗区域。
可以理解，在其它实施例中，每组清洗组件也可包括多个清洗件432，每个清洗件432均设有面向换热器本体20的清洗面，位于换热器本体20同一侧的清洗面共同界定形成一个清洗平面。
由于两组清洗组件分别固接于传动带414的两段直行段，而传动带414的两段直行段的运动方向平行且相反，因此两组清洗组件的运动方向平行且相反。当其中一组清洗组件位于换热器本体20的长度方向上的一端时，另一组清洗组件432位于换热器本体20的长度方向上的另一端。
如此，当该清洗装置40处于初始状态时，两组清洗组件分别一左一右位于换热器本体20的长度方向上的两端。当该清洗装置40运行时，其中一组清洗组件自右向左运动，另一组清洗组件则自左向右运动，从而逐渐清洗换热器100的两个待清洗面。当自右向左运动的一组清洗组件到达行程最左侧时，另一组自左向右运动的清洗组件也同时到达形成最右侧。此时，向驱动结构41输入相反的动力源，则可使两个清洗组件沿原路返回完成对换热器本体20的二次洗刷。如此，两组清洗组件在不断输入相反动力源的驱动结构41的驱动下不断往复运动，完成对换热器本体20的清洗动作，从而避免换热器本体20因长期运行产生蒸发结垢，保证换热器100的换热稳定性。
如图3、图5及图6所示，具体在一实施例中，清洗件432包括固定杆4321及清洗刷4323，固定杆4321与清洗刷4323的延伸方向均和换热器100主体的宽度方向相同。进一步地，固定杆4321可通过焊接、紧固件固定等方式固接于传动带414的直行段朝向换热器本体20一侧，清洗刷4323设于固定杆4321朝向换热器本体20的一侧，从而形成朝向换热器本体20的清洗面。进一步地，在一实施例中，固定杆4321开设有安装槽，清洗刷4323可拆卸地卡持于安装槽，因此可便于清洗刷4323的更换而无需拆卸固定杆4321。在一实施例中，清洗刷4323为毛刷，可以理解，在其它实施例中，清洗刷4323也可采用其它材料(例如海绵)制成。
如图1、图2及图4所示，两组导向组件45间隔设置于换热器本体20的宽度方向上的两端，导向组件45的延伸方向与换热器本体20的长度方向相同，清洗组件432的两端分别限位于两组导向组件45并可沿导向组件45移动。
如此，驱动结构41驱动清洗组件432沿着导向组件45不断运动以清洗换热器100，清洗组件432在导向组件45的限位下不易晃动、偏移，可达到良好的清洗效果。可以理解，在其它实施例中，也可仅设置一组导向组件45位于清洗组件432的上端或下端，也可不设置导向组件45。
具体在一实施例中，导向组件45包括在清洗面的间隔方向(即换热器本体20的厚度方向)上间隔设置且相互平行的两根导轨452，导轨452的延伸方向与换热器本体20的长度方向相同。两根导轨452的两端分别通过连接件固接于换热器本体20，其中一根导轨452与其中一组清洗组件432配合。如此，两组清洗组件432分别沿两根导轨452滑动而避免相互干扰。
进一步地在一实施例中，如图3所示，导轨452开设有导向槽4521，清洗组件432设有与导向槽4521匹配的卡持部4321b，卡持部4321b卡持于导向槽4521内并可在导向槽4521内滑动。
具体地，导轨452包括底壁、与底壁平行且间隔设置的顶壁、以及两个自底壁的两侧延伸至侧壁两侧的侧壁，底壁、顶壁及侧壁共同形成导向槽4521，顶壁开设有连通导向槽4521的开口。清洗组件432的固定杆4321的横截面呈“T”字型结构，固定杆4321包括用于安装清洗刷4323的连接部4321a及突设于连接部4321a的长度方向的两端的卡持部4321b，且连接部4321a沿换热器本体20的宽度方向延伸，卡持部4321b收容于导向槽4521内并可沿导向槽4521滑动。可以理解，导轨452与清洗组件432的配合结构不限于此，可根据需要设置呈不同的形状。清洗组件432的卡持部4321b上还可安装滑轮以使清洗组件432的移动更加顺畅。
上述清洗装置40及设有其的换热器100，清洗装置40的清洗组件可沿换热器本体20的长度方向往复运动，与换热器100喷淋过程的淋水配合，及时带走换热器本体20上的污垢，污垢可跟随流水通过排污口排出，从而使换热器100的换热管上不会有污垢沉积，具有较高的换热稳定性。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
