可选的，该第一换热部1、第二换热部2的进口端分别为最外侧换热管3的顶部接口；该第一换热部1、第二换热部2的出口端分别为最内侧换热管3的底部接口。
可选的，该第一连接组件包括第一连通装置51、用于固定该第一换热部1的第一管板52和用于固定该第二换热部2的第二管板53；该第一管板52、第二管板53相对设置，通过螺栓固定；该第一连通装置51设置在该第一管板52、该第二管板53之间，输入端连接介质输入管道，第一输出端连接该第一换热部1的进口端，第二输出端连接该第二换热部2的进口端。该第一管板52与第二管板53对向设置，顶部和底部分别通过两个固定螺栓进行固定，该顶部的两个固定螺栓之间为中空通道，通有介质输入管道。
可选的，该第二连接组件包括第二连通装置61，用于固定该第一换热部1的第三管板62和用于固定该第二换热部2的第四管板63；该第三管板62、第四管板63相对设置，通过螺栓固定；该第二连通装置61设置在该第三管板62、该第四管板63之间，第一输入端连接该第一换热部1的出口端，第二输入端连接该第二换热部2的出口端，输出端连接介质输出管道。该第三管板62、第四管板63对向设置，顶部和底部分别通过两个固定螺栓进行固定，该底部的两个固定螺栓之间为中空通道，通有介质输出管道。
该第一连接组件、第二连接组件在换热器中起到固定换热部、为介质进行导流的作用。介质输入管道连接第一连通装置51，分为两路分别进入第一换热部1、第二换热部2最外侧换热管3的顶部接口，进入换入管道内开始与空气侧进行换热，换热结束后，分别通过第一换热部1、第二换热部2最内侧换热管3的底部接口进入第二连通装置61进行汇合，合成一路后，经介质输出管道内流出。完成介质自换热部最外侧向最内侧流动换热的过程，使得介质能充分换热，实现均匀换热。
可选的，该第一管板52、第二管板53、第三管板62、第四管板63上均设有多个供换热管3穿过的通孔；该换热管3穿过通孔后，通过连接管7串联连通。管板用于固定换热管3，换热管3自通孔穿过后，在第一管板52、第二管板53之间，或，第三管板62、第四管板63之间通过连接管7与相邻换热管3连接。该第一换热部1的多个换热管3，顶部穿过第一管板52，底部穿过第三管板62；该第二换热部2的多个换热管3，顶部穿过第二管板53，底部穿过第四管板63。该多个换热管3穿过各管板后，相邻的两根换热管3之间通过连接管7，形成回路，实现介质在换热部内的流动通路，使得介质流动顺畅，能够实现均匀换热。
可选的，该连接管7包括与换热管管径相同的弯头，使得介质在换热管3内流通顺畅，均匀换热。

在另一个可选实施例中，该换热管的管径范围为5至7毫米，可以是5毫米、6毫米或7毫米。管径过大，会使得换热管中部的介质距离换热管边缘的距离较远，无法进行充分换热，会使得换热不均；管径过小会增大冷媒在换热器里的阻力，增大压力损失。因此，设定换热管的管径范围使得换热管内的介质能更加充分的与空气侧进 行换热，实现换热均匀的效果。可选的，该连接管7的管径尺寸与换热管相同。
在另一个可选实施例中，该换热器的换热管间距范围为19至21毫米。换热管间距的数值为根据连接管7管径尺寸确定的固定值；例如：当该连接管7的管径为5毫米时，该换热管间距为19.5毫米；当该连接管7的管径为7毫米时，该换热管管间距为21mm。
在另一个可选实施例中，该第一换热部1、第二换热部2的换热管3的数量均为时，该第一管板52、第二管板53、第三管板62、第四管板63上分别设有个通孔，该各管板后连接管7的数量均为个,其中，为奇数。可选的，不小于7。该换热器的换热管的数量多少与该换热器的面积大小成正比，换热管的管间距为根据管径尺寸确定的固定值，当换热器面积越大，所需的换热管就越多，介质在换热器内的换热路径就越长，换热效果更好。可选的，当该第一换热部1、第二换热部2换热管3的数量均为7个，该第一管板52、第二管板53、第三管板62、第四管板63上分别设有7个通孔。通过连接管7将穿过管板的换热管两两连通，形成串联回路，使得介质能够在换热部内自最外侧向内侧充分进行均匀换热。

由于换热部上分别安装有散热片4，形成圆盘形结构后，散热片4的数量也自近圆心端向远圆心端逐渐增多，该结构符合风量的分布规律，能更加充分的利用风量进行换热。
可选的，该第一换热部1、第二换热部2的进口端分别为最外侧换热管3的顶部接口；该第一换热部1、第二换热部2的出口端分别为最内侧换热管3的底部接口。

该第一连接组件、第二连接组件在换热器中起到固定换热部、为介质进行导流的作用。介质输入管道连接第一连通装置51，分为两路分别进入第一换热部1、第二换热部2最外侧换热管3的顶部接口，进入换入管道内开始与空气侧进行换热，换热结束后，分别通过第一换热部1、第二换热部2最内侧换热管3的底部接口进入第二连通装置61进行汇合，合成一路后，经介质输出管道内流出。完成介质自换热部最外侧向最内侧流动换热的过程，使得介质能充分换热，实现均匀换热。
可选的，该第一管板52、第二管板53、第三管板62、第四管板63上均设有多个供换热管3穿过的通孔；该换热管3穿过通孔后，通过连接管7串联连通。管板用于固定换热管3，换热管3自通孔穿过后，在第一管板52、第二管板53之间，或，第三管板62、第四管板63之间通过连接管7与相邻换热管3连接。该第一换热部1的多个换热管3，顶部穿过第一管板52，底部穿过第三管板62；该第二换热部2的多个换热管3，顶部穿过第二管板53，底部穿过第四管板63。该多个换热管3穿过各管板后，相邻的两根换热管3之间通过连接管7，形成回路，实现介质在换热部内的流动通路，使得介质流动顺畅，能够实现均匀换热。
可选的，该连接管7包括与换热管管径相同的弯头，使得介质在换热管3内流通顺畅，均匀换热。
可选的，该空调器室外机还包括设置在换热器一侧的轴流风扇8。通过将轴流风扇8设置在换热器的对面侧，正对组成圆盘形换热器的换热管3吹风，加快换热。如图3所示，轴流风扇8向外吹风时，内圈风量小，外圈风量大。可选的，该轴流风扇8为离心风扇。轴流风扇的风量分布为外圈风大，内圈风小；改进后的换热器，介质自圆盘形的最外侧向内侧流动，散热片的分布也自内向外逐渐增多，符合风量的分布规律，能充分性进行散热，实现均匀换热。
采用图2示出的空调器室外机，通过在圆盘形换热器9的对面侧设置轴流风扇8，向换热器吹风，加快空气流通速度，提高换热效率；圆盘形换热器9内的介质流向为自外侧向内侧流动，并且散热片的数量也由外向内逐渐减少，符合轴流风扇自外圈向内圈风量逐渐变小的风量分布规律，实现均匀换热。
