如图3所示，所述机柜10还设有扰流翼片17，所述扰流翼片17设置于所述腔体中，用于将所述内循环气流A与所述外循环气流B变为涡流。使用时，所述扰流翼片17可使气流产生切向旋转，从而形成沿气流流动方前进的纵向涡。所述纵向涡可产生旋转卷吸作用，从而增强导热板15的换热作用。
可以理解的是，所述扰流翼片17可设置于所述内腔110或外腔130中，也可同时设置于所述内腔110与外腔130中。
具体的，机柜10内的所述内循环气流A与外循环气流B沿平行于所述导热板15的方向流动。如图3，所述扰流翼片17与内循环气流A及/或所述外循环气流B之间的夹角α为15度至75度，较优的，所述扰流翼片17与内循环气流及/或所述外循环气流之间的夹角α为45度。所述扰流翼片17可扰动流经其的气流，从而使气流变为纵向涡流。所述扰流翼片17可采用三角形翼片、矩形翼片、梯形翼片、平行四边形翼片。优选的，所述扰流翼片17采用三角形。
所述扰流翼片17可采用任意适用方式设置于所述内腔110/外腔130之中。所述导热板15可采用金属或其他适用的高导热材料制成。
在本实施例中，所述机柜10还设有连接件19，所述连接件19用于将所述扰流翼片17设置于所述内腔110及/或外腔130。在本实施例中，所述连接件19呈平板状，所述扰流翼片17设置于所述连接件19。所述连接件19可采用任意适用方式连接于所述机柜10的内壁11、外壁13或导热板15。进一步的，所述扰流翼片17可一体成型于所述连接件19，所述扰流翼片17相对于所述连接件19弯折。所述连接件19可采用焊接、胶结等方式连接于所述机柜10的内壁11、外壁13或导热板15。可以理解的是，所述扰流翼片17也可直 接设置于所述机柜10的内壁11、外壁13或导热板15之上，只需保证所述扰流翼片17可产生扰流且不会破坏所述导热板15的隔绝效果即可。
在本实施例中，所述连接件19连接于所述导热板15，从而便于设置于所述连接件19的扰流翼片17对靠近所述导热板15的气流进行扰流，从而加强导热板15的换热效果。
本发明的机柜10通过设置导热板15，并配合机柜10的内壁11及外壁13，与导热板15的内侧与外侧形成用于气流循坏的内腔110与外腔130，使机柜10的内部空间与外部空间之间的热量通过导热板15进行交换。由于导热板15将内腔110与外腔130相互隔离，因此可保证机柜10的内部密封效果。另，本发明的机柜10通过设置扰流翼片17，可在仅仅小幅度增加气流的流动阻力的情况下，大幅度增加导热板15的换热能力，提升机柜10整体散热效率。
请参阅图3至图5，本发明的第二实施例提供一种机柜20，本实施例中的机柜20与第一实施例提供的机柜10大致相同，包括内壁21、外壁13，导热板25。所述内壁21与外壁23之间形成腔体，所述导热板25设置于所述内壁21与所述外壁23之间，并将所述腔体分隔为相互隔绝的内腔210与外腔230。所述内腔210与所述机柜20的内部相互连通以形成内循环气流，所述外腔230与所述机柜20的外部相互连通以形成外循环气流。所述机柜20还设有扰流翼片27，所述扰流翼片27设置于所述腔体中，用于将所述内循环气流与所述外循环气流变为涡流。
不同之处在于：在本实施例中，所述导热板25呈曲折状，其上设有至少两个朝向所述内壁21的凸起的第一凸部251及至少两个朝向所述外壁23凸起的第二凸部252。
相邻的两个第一凸部251之间的间隙形成用于供内循环气流流动的第一气道26。相邻的两个第二凸部252之间的间隙形成的用于供外循环气流流动的第二气道28。所述第一气道中26设有至少一个扰流翼片27。所述第二气道28中设有至少一个扰流翼片27。
本实施例中的导热板25呈曲折状，从而可增加导热板25的散热面积，提升导热板25的散热效果。同时导热板25上设置的第一凸部251及第二凸部252可形成供气流流动的第一气道26与第二气道28。第一气道26、第二气道28之中设置扰流翼片27，便于使第一气道26、第二气道28之中气流形成纵 向涡，提升扰流翼片27的扰流效率。
在本实施例中，所述第一凸部251与第二凸部252的截面形状呈矩形。可以理解的是，所述第一凸部251与第二凸部252的截面形状也可设为V型、U型或梯形等其他形状，只需保证相邻的两个第一凸部251可形成第一气道26、相邻的两个第二凸部252可形成第二气道28即可。
进一步的，每个所述第一气道26或每个第二气道28中设有至少一对扰流翼片27，每对扰流翼片27中的两个扰流翼片27镜像对称。通过设置一对扰流翼片27，可于风道中形成两个旋转方向相反的纵向涡。
进一步的，在本实施例中，机柜20设置连接件29，用于将扰流翼片27设置于所述腔体中。所述连接件29为U型片状，且其可夹持固定于所述第一凸部251或第二凸部252。在本实施例中，所述扰流翼片27与所述连接件29一体成型并相对于所述连接件29弯折。所述连接件29可夹持固定于所述第一凸部251、第二凸部252，从而使设置于所述连接件29外侧的扰流翼片27置于所述第一气道26、第二气道28之中。可以理解的是，所述连接件29也可采用焊接的方式固定连接于所述导热板25。所述扰流翼片27也可直接焊接于所述导热板25之上。
请参阅图6，本发明的第三实施例提供一种机柜30，本实施例中的机柜30与第一实施例提供的机柜20大致相同，包括内壁31、外壁33，导热板35。所述内壁31与外壁33之间形成腔体，所述导热板35设置于所述内壁31与所述外壁33之间，并将所述腔体分隔为相互隔绝的内腔310与外腔330。所述内腔310与所述机柜30的内部相互连通以形成内循环气流，所述外腔330与所述机柜30的外部相互连通以形成外循环气流。所述机柜30还设有扰流翼片37，所述扰流翼片37设置于所述腔体中，用于将所述内循环气流与所述外循环气流变为涡流。在本实施例中，所述导热板35呈曲折状，其上设有至少两个朝向所述内壁31的凸起的第一凸部351及至少两个朝向所述外壁33凸起的第二凸部352。相邻的两个第一凸部351之间的间隙形成用于供内循环气流流动的第一气道36。相邻的两个第二凸部352之间的间隙形成的用于供内循环气流流动的第二气道38。
不同之处在于：本实施例中的相邻的两个第一凸部351之间的间隙小于相邻的两个第二凸部352之间的间隙。从而使所述第一风道36的截面面积小于 第二风道38的截面面积。从而便于使与机柜30外部相连通的第二风道38具有较大的气流流量，进而提升机柜30的换热效果。
进一步的，所述机柜30设有定位架34及连接件39。所述扰流翼片37通过所述连接件39及定位架34固定安装于所述导热板35。在本实施例中，所述定位架34设置于外腔330中。
所述定位架34呈板状并设置于所述导热板35的第二凸部352外侧，且所述定位架34大致平行于所述外壁33。所述定位架34的两端固定连接于所述导热板35。
所述连接件39中部设有卡勾390，所述卡勾390用于连接所述定位架34。所述扰流翼片37设置于所述连接件39外侧。所述连接件39夹持固定于所述第二凸部352，所述扰流翼片37位于所述第二风道38中。
在本实施例中，一个所述定位架34设有多个扰流翼片37，所述连接件39的设置数量与所述导热板35的第二凸部352的数量相同，即每个第二凸部352均对应共设有一个连接件39，每个连接件39上设有若干个扰流翼片37。
进一步的，在本实施例中，所述连接件39每侧设有两对扰流翼片37，每对扰流翼片37中的两个扰流翼片37镜像对称。
可以理解的是，所述定位架34也可设置于所述内腔310中，其固定安装方式与前述一致，在此不再赘述。所述连接件39可夹持固定于所述第一凸部351、第二凸部352，从而使设置于所述连接件39外侧的扰流翼片37置于所述第一气道36、第二气道38之中。可以理解的是，所述连接件39也可采用焊接的方式固定连接于所述导热板35。所述扰流翼片37也可直接焊接于所述导热板35之上。
进一步的，所述机柜30可设置多个相互平行的定位架34，每个定位架34上设有至少多个用于设置扰流翼片37的连接件39。如图所述，本实施例中所述多个定位架34沿所述多个第二风道38的延伸方向依次相互排布，且设置于相邻两列定位架34之上的扰流翼片37位于不同的第二风道38中，从而保证在第二风道38中气流方向上的扰流翼片37的设置不会过于密集，从而导致气流的流动阻力过大。
以上所揭露的仅为本发明一种实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程， 并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
