下面参考附图描述根据本发明实施例的换热器100，本发明实施例的换热器100可以为微通道换热器。
如图1-图5所示，根据本发明实施例的换热器100包括第一集流管10、第二集流管20、换热管30、第一隔板41、第二隔板42和多个换热管30。
具体地，第二集流管20与第一集流管10相隔开一定距离设置，多个换热管30设在第一集流管10和第二集流管20之间，且多个所述换热管30沿所述第一集流管10的轴向方向相隔开一定距离设置。换热管30的第一端与第一集流管10连接，换热管30的第二端与第二集流管20连接，换热管30连通所述第一集流管10的内腔与所述第二集流管20的内腔。
如图1-图5所示，第一集流管10和第二集流管20相隔开一定距离，换热管30的第一端与第一集流管10相连接，换热管30的第二端与第二集流管20相连，且换热管30连通第一集流管10的内腔和第二集流管20的内腔，制冷剂可在换热管30、第一集流管10和第二集流管20内流动。
第一隔板41和第二隔板42同时位于第一集流管10的内腔，第一隔板41和第二隔板42将第一集流管10内腔分割成第一腔体11、第二腔体12和第三腔体13，沿第一集流管10的轴向方向，第二腔体12位于第一腔体11与第三腔体13之间。第一腔体11和第三腔体13通过第二腔体12阻隔开，第二腔体12与第一腔体11和第三腔体13之间不流通。
如图3所示，制冷剂可从第一腔体11通过换热管30流向第二集流管20，然后通过换热管30流向第三腔体13，本实施例通过设置第一隔板41和第二隔板42，相比相关技术中仅在相邻流程之间设置一个隔板，可防止一个隔板时导致隔板两侧温差较大，进而可避免一 个隔板两侧温差较大导致邻近隔板的换热管30产生温度交替变化而产生温度疲劳。从而减小了相邻流程的换热管30之间的温差，以相对降低相邻流程的换热管30产生裂痕的可能性。
多个换热管30中的一部分连通第一腔体11和第二集流管20，多个换热管30的一部分连通第三腔体13连通第三腔体13和第二集流管20，制冷剂在第一集流管10和第二集流管20以及多个换热管30内流动，由此可将换热管30内的制冷剂流路分成两个流程，即第一流程31和第二流程32。连通第一腔体11和第二集流管20的内腔的换热管30内的制冷剂流路构成第一流程31，连通第二集流管20的内腔和第三腔体13的换热管30内的制冷剂流路构成第二流程32，制冷剂在第一流程31和第二流程32的流动方向相反。
这样，第一腔体11内的制冷剂通过第一流程31和第二流程32换热后流向第三腔体13，制冷剂在相邻流程内流动，由于相邻流程内的制冷剂经过的换热程度不同，使得相邻流程的制冷剂的温度不同，由此导致相邻流程的相邻换热管30之间容易产生温差。第一隔板41和第二隔板42设在第一集流管10内可将集流管的内腔沿轴向方向分隔开以形成三个单独的腔室，由此由于相邻流程的制冷剂的温度不同，第二腔体12的两侧的腔室的温度不同，在第一集流管10内可形成有与相邻流程中一个流程连通的制冷剂的高温区腔室、与相邻流程的另一个流程连通的制冷剂的低温区腔室，通过第二腔体12将高温区和低温区间隔开，从而使得换热管30承受的温差减少，避免了热应力，相对降低换热管30产生裂痕的概率。
由此，根据本发明实施例的换热器100，通过在第一集流管10内设置第一隔板41和第二隔板42以将第一集流管10的内腔分割为第一腔体11、第二腔体12和第三腔体13，从而可防止相邻流程的换热管30的由于温度产生交替变化导致产生温度疲劳而出现应力裂痕，进而可相对降低由于换热管30产生裂痕而使得换热器100发生泄露的概率，以相对提高换热器100的可靠性。
在如图1-图3所示的示例中，制冷剂进口14和制冷剂出口15设在第一集流管10，第一隔板41和第二隔板42均位于制冷剂进口14和制冷剂进口14之间，制冷剂可通过制冷剂进口14进入第一腔体11，然后流向第一流程31，并流向第二集流管20，之后流向第二流程32，最后从制冷剂进口14流出。
在本发明的一些实施例中，换热器还可以包括第三隔板43和第四隔板44，第三隔板43和第四隔板44同时位于第二集流管20的内腔，第三隔板43和第四隔板44将第二集流管20的内腔分割成第四腔体21、第五腔体22和第六腔体23，沿第二集流管20的轴向方向，第五腔体22位于第四腔体21与第六腔体23之间，在第二集流管20内，第四腔体21、第五腔体22和第六腔体23不连通。
至少部分换热管30的内腔连通第三腔体13和第四腔体21，至少部分换热管30的内腔连通第六腔体23和第三腔体13，第五腔体22沿第二集流管20向第一集流管10的方向在 第一集流管10内腔的垂直投影位置处未设置有隔板。
由此，制冷剂在第一集流管10和第二集流管20之间通过换热管30流通，可将制冷剂的流程分为三个，即第一流程31、第三流程33和第四流程34，通第一腔体11和第四腔体21的换热管30内的制冷剂流路构成第一流程31，连通第四腔体21和第三腔体13的换热管30内的制冷剂流路构成第三流程33，连通第三腔体13和第六腔体23的换热管30内的制冷剂流路构成第四流程34，制冷剂在第一流程31、第四流程34的流动方向与第三流程33的流动方向相反。
具体地，如图4所示，第一腔体11和第三腔体13分别设在第二腔体12的两侧，通过第二腔体12将第一腔体11和第三腔体13间隔开以进行隔热，第四腔体21和第六腔体23分别位于第五腔体22的两侧，通过第五腔体22将第四腔体21和第六腔体23间隔开以进行隔热，第一流程31的换热管30连通第一腔体11和第四腔体21，第三流程33的换热管30连通第四腔体21和第三腔体13，第四流程34的换热管30连通第三腔体13和第六腔体23。
制冷剂从第一腔体11通过第一流程31的换热管30流向第四腔体21，然后通过第三流程33的换热管30流向第三腔体13，制冷剂在第三腔体13通过第三流程33的换热管30流向第六腔体23。
这样，第一腔体11内的制冷剂经过第一流程31和第三流程33的换热管30换热后流向第三腔体13，由此第一腔体11内的制冷剂和第三腔体13的制冷剂存在温差，第二腔体12位于第一腔体11和第三腔体13之间，从而可减小第一流程31和第三流程33的换热管30的温差。第三腔体13的制冷剂通过第四流程34的换热管30流向第六腔体23，这样，第四腔体21内的制冷剂通过第三流程33和第四流程34的换热管30换热后流向第六腔体23，由此，第四腔体21内的制冷剂和第六腔体23的制冷剂存在温差，第五腔体22位于第四腔体21和第六腔体23之间，从而可减小第四流程34和第三流程33的换热管30的温差。进而可相对降低三个流程的换热管30由于热应力变化而产生裂痕的概率。
其中制冷剂进口14设在第一集流管10，制冷剂出口15设在第二集流管20，制冷剂从制冷剂进口14进入第一腔体11，之后依次经过第一流程31的换热管30、第四腔体21、第三流程33的换热管30、第三腔体13、第四流程34的换热管30和第六腔体23，最后从制冷剂出口15流出。
在本发明的另一些实施例中，换热器还包括第五隔板45和第六隔板46，第五隔板45和第六隔板46同时位于第三腔体13，第五隔板45和第六隔板46将第三腔体13分割成第七腔体131、第八腔体132和第九腔体133，沿第二集流管20的轴向方向，第八腔体132位于第七腔体131与第九腔体133之间，在第三腔体13内，第八腔体132、第七腔体131与第九腔体133之间不连通。
其中至少部分换热管30的内腔连通第四腔体21和第七腔体131，至少部分换热管30的内腔连通第六腔体23和第七腔体131，至少部分换热管30的内腔连通第六腔体23和第九腔体133，第八腔体132沿第一集流管10向第二集流管20的方向在第二集流管20的内腔的垂直投影位置处未设置有隔板。
由此，制冷剂在第一集流管10和第二集流管20之间通过换热管30流通，可将制冷剂的流程分为四个，即第一流程31、第五流程35、第六流程36和第七流程37，通第一腔体11和第四腔体21的换热管30内的制冷剂流路构成第一流程31，连通第四腔体21和第七腔体131的换热管30内的制冷剂流路构成第五流程35，连通第七腔体131和第六腔体23的换热管30内的制冷剂流路构成第六流程36，连通第九腔体133和第六腔体23的换热管30内的制冷剂流路构成第七流程37，制冷剂在第一流程31和第六流程36的方向相同，制冷剂在第五流程35和第七流程37的方向相同且与第一流程31的流动方向相反。
具体地，如图5所示，第一腔体11和第七腔体131分别设在第二腔体12的两侧，通过第二腔体12将第一腔体11和第七腔体131隔开以进行隔热，第四腔体21和第六腔体23分别位于第五腔体22的两侧，通过第五腔体22将第四腔体21和第六腔体23间隔开以进行隔热，第七腔体131和第九腔体133分别位于第八腔体132的两侧，通过第八腔体132将第七腔体131和第九腔体133间隔开以进行隔热，第一流程31的换热管30连通第一腔体11和第四腔体21，第五流程35的换热管30连通第四腔体21和第七腔体131，第六流程36的换热管30连通第七腔体131和第六腔体23，第七流程37的换热管30连通第九腔体133和第六腔体23。
制冷剂从第一腔体11通过第一流程31的换热管30流向第四腔体21，然后通过第五流程35的换热管30流向第七腔体131，制冷剂在第七腔体131通过第六流程36的换热管30流向第六腔体23，并通过第七流程37的换热管30流向第九腔体133。
这样，第一腔体11内的制冷剂经过第一流程31和第五流程35的换热管30换热后流向第七腔体131，由此第一腔体11内的制冷剂和第七腔体131的制冷剂存在温差，第二腔体12位于第一腔体11和第七腔体131之间，从而可减小第一流程31和第五流程35的换热管30的温差。第七腔体131的制冷剂通过第六流程36的换热管30流向第六腔体23，这样，第四腔体21内的制冷剂通过第五流程35和第六流程36的换热管30换热后流向第六腔体23，由此，第四腔体21内的制冷剂和第六腔体23的制冷剂存在温差，第五腔体22位于第四腔体21和第六腔体23之间，从而可减小第四流程34和第五流程35的换热管30的温差。第八腔体132位于第七腔体131和第九腔体133之间，第七腔体131的制冷剂通过六流程和第七流程37的换热管30流向第九腔体133，从而可减小第五流程35和第六流程36的换热管30的温差。进而可相对降低四个流程的换热管30由于热应力变化而产生裂痕的概率，可 进一步保证换热器100的可靠性。
由此以此推断，隔板可以成对设置且也可为三对或者三对以上，多对隔板可设在第一集流管10内和第二集流管20内以将换热管30内的制冷剂流路分为多个流程。通过多个隔板将第一集流管10和第二集流管20分别分割为多个腔体，多个腔体之间通过换热管30对应连通以允许制冷剂流通，从而可提高换热器100的安全性。
可选地，换热器100可以包括至少一个隔热件70，隔热件70可以为实心的隔热件或者空心的隔热件，隔热件70的第一端与第一集流管10相连且位于第二腔体处，隔热件70的第二端与第二集流管20相连，从而可将相邻流程的换热管30相隔开。
具体地，隔热件70设在相邻流程的相邻换热管30之间，通过隔热件70可将相邻流程的相邻换热管30隔开，通过隔热件70从而可进一步地减小相邻流程的相邻换热管30的温差以降低换热管30产生裂痕的可能性。进一步地，隔热件70可以邻近隔板40设置，隔热件70的个数可以与隔板40的对数一致，从而可进一步地保证换热器100的可靠性。
在本发明的一些示例中，如图3所示，隔热件70的第一端可与第一集流管10相连且位于第一隔板41和第二隔板42之间，隔热件70的第二端与第二集流管20相连，其中，隔热件70的另一端可以连接至第二腔体12沿第一集流管10至第二集流管20的方向在第二集流管20的垂直投影位置处，进一步地，隔热件70可垂直第一集流管10和第二集流管20设置。
在本发明的另一些示例中，如图4所示，隔热件70两端可分别与第一集流管10和第二集流管20相连，其中隔热件70的一端可连接至第二集流管20的第五腔体22处，隔热件70的另一端可连接至第一腔体11或者第三腔体13在第一集流管10的对应位置处。可选地，隔热腔70的另一端可以连接至第五腔体22沿从第二集流管20到第一集流管10的方向在第一集流管10的垂直投影位置处，进一步地，隔热件70可垂直连接在第二集流管20的第五腔体22的对应处上和第一集流管10之间。
如图5所示，隔热件70的一端可连接至第一集流管10的形成第八腔体132的位置处，即隔热件70可连接在第五隔板45和第六隔板46之间，隔热件70的另一端连接至第八腔体132沿第一集流管10到第二集流管20的方向在第二集流管20的垂直投影位置处，进一步地，隔热件70可垂直设在第一集流管10形成第八腔体132的位置处和第二集流管20之间。
在本发明的一些示例中，隔热件70可以为隔热管，具体地，隔热件70可以形成为至少一端敞开的隔热管，例如，隔热件70的两端均可敞开，隔热件70的第一端可与隔热腔41相连通，隔热件70的第二端可与第二集流管20连通，由于隔热腔41为封闭的腔室，由此，制冷剂可流向隔热管内且储存在隔热管内，即隔热管内可设有存储有制冷剂且制冷剂不流通，从而有利于实现进一步地隔热。或者，换热管30可以为实心隔热管或者形成为两端封闭的空心隔热管，由此当隔热件70出现裂痕时，换热器100也不会发生泄露，以进一步地提高 换热器100的可靠性。而且当隔热管出现裂痕时，也可防止制冷剂发生泄漏。
在本发明的另一些示例中，隔热件70可以为隔热板，这样隔热板的两端分别与第一集流管10和第二集流管20相连。由此，不仅方便隔热件70的安装装配，而且隔热件70在第一集流管10和第二集流管20之间能够也有利于对相邻的两个换热管30进行隔热，也能够保证隔热件70的隔热效果。
进一步地，隔热件70可以由换热管30构成，第二腔体12对应的第一集流管10的管壁处设有插孔，隔热件70的第一端穿过插孔并与第一集流管10相连接，由此可将隔热件70的一端连接至第一集流管10且连接至第二腔体12处，实现对第一流程31和第二流程32的换热管30的隔热。
例如，隔热管的一端与第二腔体12连通，这样第二腔体12内的制冷剂以及隔热管内的制冷剂可以与外界进行温度传递与换热，由此，不仅能够对相邻流程的换热管30进一步地隔热，也能够保证换热器的换热效果。而且隔热管由换热管30构成，从而可不影响换热器100的整体外观，也方便安装装配，同时也能够将相邻流程的换热管30完全隔开以提高隔热效果。需要说明的是，例如隔热管为多个时，隔热管的敞开的一端与隔板之间的腔体的连通可以根据实际情况而定，例如，隔热管也可以连通第五腔体22和第一集流管10，也可以连通第八腔体132和第六腔体23。
可以理解的是，相邻流程之间的隔热件70可以为单根或者多根，多个隔热件70可以并列设置，具体可以根据温度差而定。也就是说，每两个相邻流程之间的隔热件70可以根据相邻流程的换热管30的温差设定。其中优选地隔热板的外形和尺寸可与换热管30相同。由此，隔热板设在两个换热管30之间，从而可将两个相邻换热管30完全间隔开以提高隔热效果，而且可避免隔热板材料的浪费，同时，可保证换热器100的整体外观，以方便换热器100的安装和制造。
可选地，隔热件70与换热管30之间的间距和相邻换热管30之间的距离可相同。换言之，隔热件70设在相邻流程的换热管30之间，而且隔热板与两个相邻换热管30之间的间距，与每个流程的相邻换热管30之间的距离是相同的，从而进一步地提高隔热板的隔热效果。
可选地，相邻换热管30之间可设有翅片60，通过设置翅片60从而可提高换热管30的换热效果。在如图1和2所示的示例中，翅片60可形成为波浪状，从而可增加翅片60的换热面积，进一步地提高换热器100的换热效果。进一步地，隔热件70的至少一侧与换热管30之间可设有翅片60。由此，通过翅片60可进一步地提高换热器100的换热效果，在如图所示的示例中，隔热件70的两侧与两侧的换热管30之间可均设有翅片60。
在本发明的一些实施例中，换热器100还可以包括：位于最外侧换热管30的外侧的第 一托架50和位于另一个最外侧换热管30的外侧的第二托架51，第一托架50的第一端与第一集流管10的第一端相连，第一托架50的第二端与第二集流管20的第一端相连，第二托架51第一端与第一集流管10的第二端相连，第二托架51的第二端与第二集流管20的第二端相连。通过第一托架50和第二托架51从而可支撑第一集流管10和第二集流管20，而且换热管30设在第一托架50和第二托架51之间，通过第一托架50和第二托架51也可保护换热管30。
在如图1所示的示例中，第一托架50和第二托架51分别位于多个换热管30整体的两侧(即如图1所示的上侧和下侧)，即多个换热管30位于第一托架50和第二托架51之间，第一托架50的两端分别与第一集流管10和第二集流管20相连，第二托架51的两端分别与第一集流管10和第二集流管20的相连，第一托架50和第二托架51分别支撑在第一集流管10和第二集流管20之间，通过第一托架50和第二托架51能够提高换热器100整体的结构强度和稳定性。
具体地，第一托架50具有第一端部501和第二端部502，第一端部具有第一弧形连接面(未标示)，第二端部502具有第二弧形连接面(未标示)；第二托架51具有第三端部511和第四端部512，第三端部511具有第三弧形连接面(未标示)，第四端部512具有第四弧形连接面(未标示)，第一集流管10具有位于第一集流管10轴向方向一端的第一连接部(未标示)和位于第一集流管10轴向方向另一端的第二连接部(未标示)，第二集流管20具有位于第二集流管20轴向方向一端第三连接部(未标示)和位于第二集流管20轴向方向另一端的第四连接部(未标示)；第一弧形连接面的曲率半径不小于第一连接部的外壁面的曲率半径，第一弧形连接面与第一连接部的外壁面相配合连接，第二弧形连接面的曲率半径不小于第三连接部的外壁面的曲率半径，第二弧形连接面与第三连接部的外壁面相配合连接，第三弧形连接面的曲率半径不小于第二连接部的外壁面的曲率半径，第三弧形连接面与第二连接部的外壁面相配合连接，第四弧形连接面的曲率半径不小于第四连接部的外壁面的曲率半径，第四弧形连接面与第四连接部的外壁面相配合连接。
可选地，第一托架50与与其相邻的换热管30之间设置有翅片60，第二托架51与与其相邻的换热管30之间设置有翅片60。由此，邻近第一托架5的换热管30可通过第一托架50和换热管30之间的翅片60换热，邻近第二托架51的换热管30可通过第二托架51和换热管30之间的翅片60换热，从而可增加换热器100的换热面积，提高换热效果。
本发明还提了一种换热系统，包括压缩机、冷凝器、蒸发器和节流机构，其中冷凝器和蒸发器中的至少一个为换热器100。由此，根据本发明实施例的换热系统，通过将冷凝器和蒸发器中的至少一个设置为上述实施例的换热器100，从而能够相对降低冷凝器和蒸发器出现裂痕的可能性，相对提高换热器以及换热系统的可靠性。
