Description

用于换热器的换热器管板、换热器及空调器 技术领域
本发明涉及空调技术领域，特别是涉及一种用于换热器的换热器管板、换热器及空调器。
背景技术
现有空调器的换热器，例如室外机的冷凝器、窗式空调器的蒸发器、冷凝器一般都是安装在底盘上，底盘为钣金件，换热器管板与底盘通过螺钉固定连接。由于底盘翻边是通过冲压实现，模具本身有一定的脱模斜度，冲压完成后还有一定的回弹，实际底盘翻边不是直立的，而是向外侧倾斜一定角度。当管板与底盘翻边固定连接后，管板随着底盘翻边而倾斜，换热器也随着向外侧倾斜。当换热器为蒸发器时，蒸发器会产生较多冷凝水，部分冷凝水会沿着管板向下流淌，由于管板倾斜，在底盘翻边处容易渗漏、滴水，钣金件长时间浸泡导致生锈，破坏外表面，使得用户体验变差。
发明内容
鉴于上述问题，提出了本发明以便提供一种克服上述问题或者至少部分地解决上述问题的用于换热器的换热器管板、换热器及空调器，能够防止换热器产生的冷凝水顺着管板的翻边流淌，并在底盘的翻边处出现渗漏、滴水等情况。
具体地，本发明提供了一种用于换热器的换热器管板，包括：
主板，所述主板竖直设置；
上翻边，所述上翻边从所述主板的一个竖向边缘延伸出；
下翻边，所述下翻边从所述主板的一个竖向边缘的下端延伸出；所述下翻边位于所述上翻边的下方，所述下翻边与所述上翻边间隔设置；所述下翻边倾斜设置，所述下翻边的朝向所述主板的另一竖向边缘的侧面为倾斜设置的所述下翻边的上侧面；在垂直于所述主板的方向上，所述上翻边的长度小于所述下翻边的长度；所述下翻边的上端处于所述下翻边的下端及所述上翻边的下端的外侧。

可选地，在所述主板与所述下翻边的朝向所述主板的另一竖向边缘的侧面之间设置多个加强筋板；和/或
在所述主板与所述中间翻边的朝向所述主板的另一竖向边缘的侧面之间设置多个加强筋板。
可选地，所述下翻边与垂直于所述主板的竖直平面之间的夹角为2°至15°；所述下翻边的上端与所述下翻边的下端沿水平方向的距离为3mm至10mm；所述下翻边的上端与所述下翻边的下端沿竖直方向的距离为10mm至20mm。
可选地，所述换热器管板还包括从所述主板的另一个竖向边缘延伸出的侧翻边，所述侧翻边与所述上翻边、所述下翻边处于所述主板的同一侧。
可选地，在竖直方向上，所述中间翻边的长度为5mm至20mm；
在垂直于所述主板的方向上，所述中间翻边的长度为2mm至5mm；
在垂直于所述主板的方向上，所述上翻边的长度与所述下翻边的长度之间的比值为0.5至0.9；
在竖直方向上，所述下翻边的长度与所述上翻边的长度之间的比值为0.4至0.8。
可选地，所述下翻边的下端在水平面上的投影处于所述下翻边的上端在所述水平面上的投影与所述上翻边的下端在所述水平面上的投影之间。
可选地，所述下翻边安装于接水盘的翻边上；所述上翻边垂直于所述主板，所述下翻边垂直于所述主板；
所述下翻边上设置有第一安装孔，所述接水盘的翻边上对应位置处设置有第二安装孔，所述下翻边通过所述第一安装孔、所述第二安装孔和紧固件安装于所述接水盘的翻边上。

本发明的用于换热器的换热器管板中，上翻边位于下翻边的上方，且间隔设置，下翻边的上端处于下翻边的下端及上翻边的下端的外侧。换热器产生的冷凝水顺着上翻边向下流淌，并滴落在下翻边上，通过下翻边的收集作用流到接水盘内，最后通过正常排水渠道排出。即使换热器管板与换热器倾斜，也能够使得换热器产生的冷凝水流到接水盘内，而不会渗漏到换热器管板外侧。因此，本发明的用于换热器的换热器管板，能够防止换热器产生的冷凝水顺着换热器管板的翻边流淌，并在接水盘的翻边处出现渗漏、滴水等情况。
进一步地，下翻边倾斜设置，当下翻边安装于接水盘的翻边上后，能够保证换热器管板的主板和换热器竖直，能够防止换热器倾斜后，上侧位移较大，与其他结构件的配合出现问题。

图1是根据本发明一个实施例的用于换热器的换热器管板的示意性结构图，如图1所示，并参考图2至图4，本发明实施例提供了一种用于换热器的换热器管板100，包括主板110、上翻边120和下翻边130。主板110竖直设置。上翻边120从主板110的一个竖向边缘延伸出。下翻边130从主板110的一个竖向边缘的下端延伸出。下翻边130位于上翻边120的下方。下翻边130与上翻边120间隔设置。下翻边130倾斜设置，下翻边130的朝向主板110的另一竖向边缘的侧面为倾斜设置的下翻边130的上侧面。在垂直于主板110的方向上，上翻边120的长度小于下翻边130的长度。当然，在垂直 于主板110的方向上，上翻边120的长度也可等于或大于下翻边130的长度。下翻边130的上端处于下翻边130的下端及上翻边120的下端的外侧。
本发明实施例的用于换热器的换热器管板100中，上翻边120位于下翻边130的上方，且间隔设置，下翻边130的上端处于下翻边130的下端及上翻边120的下端的外侧。换热器产生的冷凝水顺着上翻边120向下流淌，并滴落在下翻边130上，通过下翻边130的收集作用流到接水盘200内，最后通过正常排水渠道排出。即使换热器管板100与换热器倾斜，也能够使得换热器产生的冷凝水流到接水盘200内，而不会渗漏到换热器管板100外侧。因此，本发明的用于换热器的换热器管板100，能够防止换热器产生的冷凝水顺着换热器管板100的翻边流淌，并在接水盘的翻边210处出现渗漏、滴水等情况。
一般地，现有空调器的换热器，例如室外机的冷凝器、窗式空调器的蒸发器、冷凝器都是安装在接水盘上，接水盘为钣金件，换热器管板与接水盘通过螺钉固定连接。此时，接水盘为底盘。由于接水盘的翻边是通过冲压实现，模具本身有一定的脱模斜度，冲压完成后还有一定的回弹，实际上接水盘的翻边不是直立的，而是向外侧倾斜一定角度。当换热器管板与接水盘的翻边固定连接后，随着接水盘的翻边倾斜，换热器管板及换热器也随着向外侧倾斜。换热器倾斜会导致换热器上侧位移较大，与其他结构件的配合出现问题。进一步地，在本发明实施例的用于换热器的换热器管板100中，下翻边130倾斜设置，当下翻边130安装于接水盘的翻边210上后，能够保证换热器管板100的主板110和换热器处于竖直状态，能够防止换热器倾斜后，换热器的上侧位移较大，与其他结构件的配合出现问题。而且，下翻边130向外凸出，且倾斜方向向外。这样设置，使得下翻边130不占用换热器的换热管的安装空间，进而使得结构紧凑、体积较小。
在本发明的一些实施例中，如图1至图4所示，从主板110的一个竖向边缘延伸出中间翻边140。中间翻边140竖直设置，中间翻边140处于下翻边130的上方，中间翻边140的上端的高度低于上翻边120的下端的高度。在中间翻边140的背离主板110的另一竖向边缘的侧面与主板110的连接处冲压出沿水平方向延伸的凹槽141，凹槽141的截面为三角形。例如，冲压使用的模具为楔形块，利用楔形块的尖端冲压出该凹槽141。由于设置有中间翻边140，中间翻边140上冲压出凹槽141，且中间翻边140与下翻边130 连接，提高了下翻边130的连接强度，防止下翻边130在受外力时折弯变形。
在本发明的一些实施例中，在主板110与下翻边130的朝向主板110的另一竖向边缘的侧面之间设置多个加强筋板。加强筋板可起到提高下翻边130的连接强度的作用。为了提高中间翻边140的连接强度，在主板110与中间翻边140的朝向主板110的另一竖向边缘的侧面之间设置多个加强筋板。
在本发明的一些实施例中，下翻边130与垂直于主板110的竖直平面之间的夹角为2°至15°。本实施例中给出的角度适用于大部分的情况，其角度还可根据接水盘200的翻边的实际倾斜角度进行调整。下翻边130的上端与下翻边130的下端沿水平方向的距离为3mm至10mm。下翻边130的上端与下翻边130的下端沿竖直方向的距离为10mm至20mm。当然，下翻边130的尺寸可根据用于安装下翻边130的接水盘200的翻边的尺寸等实际情况进行调整。
在本发明的一些实施例中，如图3和图4所示，换热器管板100还包括从主板110的另一个竖向边缘延伸出的侧翻边150，侧翻边150与上翻边120、下翻边130处于主板110的同一侧。侧翻边150能够增强主板110的强度，防止主板110在受到外力时发生弯折变形。
在本发明的一些实施例中，中间翻边140沿竖直方向的长度为5mm至20mm。在垂直于主板110的方向上，中间翻边140的长度为2mm至5mm。当然中间翻边140的尺寸可根据主板110、安装板和第二翻边的尺寸等实际情况进行调整。在垂直于主板110的方向上，上翻边120的长度与下翻边130的长度之间的比值为0.5至0.9，优选地，比值为0.7。在竖直方向上，下翻边130的长度与上翻边120的长度之间的比值为0.4至0.8，优选地，比值为0.6。当然，上述比值只是给出的较优的数值，上述比值也可根据实际情况进行调整。
在本发明的一些实施例中，如图4所示，下翻边130的下端在水平面上的投影处于下翻边130的上端在水平面上的投影与上翻边120的下端在水平面上的投影之间。或者，上翻边120的下端在水平面上的投影处于下翻边130的上端在水平面上的投影与下翻边130的下端在水平面上的投影之间。
在本发明的一些实施例中，如图4所示，下翻边130安装于接水盘200的翻边210上。下翻边130上设置有第一安装孔，接水盘200的翻边210上 对应位置处设置有第二安装孔，下翻边130通过第一安装孔、第二安装孔和紧固件安装于接水盘200的翻边。例如，第一安装孔为螺纹孔，第二安装孔为光孔，紧固件为螺钉，螺钉穿过第二安装孔并与第一安装孔通过螺纹连接。当然，第一安装孔与第二安装孔均可为光孔，紧固件为螺栓和螺母，螺栓依次穿过第二安装孔、第一安装孔并与螺母连接。
本发明实施例还提供了一种换热器，换热器包括换热管和上述任一实施例中的换热器管板100，换热器管板100的数量为两个，换热管安装于两个换热器管板100的主板110上。具体地，主板110上开设有多个安装管孔，换热管穿过安装管孔，并固定在主板110上，防止换热管晃动。两个换热器管板100使得换热管的两端都固定连接在换热器管板100上，进而使得换热管固定更加牢固。
本发明实施例还提供了一种空调器，包括接水盘200和上述实施例中的换热器，下翻边安装于接水盘的翻边上。换热器为蒸发器和/或冷凝器。接水盘可为底盘。在本发明的另一些实施例中，换热器可通过其他结构安装于接水盘200的上侧
本发明实施例的空调器中，上翻边120位于下翻边130的上方，且间隔设置，下翻边130的上端处于下翻边130的下端及上翻边120的下端的外侧。换热器产生的冷凝水顺着上翻边120向下流淌，并滴落在下翻边130上，通过下翻边130的收集作用流到接水盘200内，最后通过正常排水渠道排出。即使换热器管板100与换热器倾斜，也能够使得换热器产生的冷凝水流到接水盘200内，而不会渗漏到换热器管板100外侧。因此，本发明的空调器，能够防止换热器产生的冷凝水顺着换热器管板100的翻边流淌，并在接水盘的翻边210处出现渗漏、滴水等情况。
进一步地，当下翻边130安装于接水盘200的翻边210上后，下翻边130倾斜设置，能够保证换热器管板100的主板110和换热器竖直，能够防止换热器倾斜后，上侧位移较大，与其他结构件的配合出现问题。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
