如图1-图8所示，同一板片折叠形成多个换热板片2，奇数层的换热板片2结构相同，偶数层的换热板片2结构相同，即第一板片10和第三板片30的结构相同，当然，换热器1也可以仅具有三个换热板片2，即第一板片10、第二板片20和第三板片30，第一板片10和第三板片30的结构也可以不同。
如图1-图13所示，第二板片20包括第一基部21和相对第一基部21凸出的第一凸部22，第一凸部22为环形，第一凸部22围绕第二流通通道4设置，第一凸部22与第三板片30密封设置，第一凸部22的设置实现第二板片20与第三板片30密封设置，并且第一凸部22保证第二流通通道4具有一定的高度，通过调整第一凸部22的高度可以调整第二流通通道4的高度。第一板片10与位于第一凸部22外围的第一基部21密封设置，第一连接部50的长度小于第二连接部60的长度，通过缩短第一连接部50的长度，不仅降低成本，而且减小换热器1的重量。当然，也可以在位于第一凸部22内侧的第一基部21设置朝向第一板片10凸出的环形凸起与第一板片10密封设置实现第一流通通道3周围的密封，或者，在第一板片10设置朝向第二板片20凸出的环形凸起与位于第一凸部22内侧的第一基部21密封以实现第一流通通道3周围的密封，或者，在位于第一凸部22内侧的第一基部21设置朝向第一板片10凸出的环形凸起，并且在第一板 片10设置朝向第二板片20凸出的环形凸起，并且将两个环形凸起密封设置以实现第一流通通道3周围的密封。此处指的密封设置具体可以采用钎焊固定，或者采用密封胶固定等。
在一些具体实施例中，第一流通通道3和第二流通通道4设置用于扰流的凸起。如图1-图12所示，换热器1还包括第四板片40，第三板片30位于第二板片20与第四板片40之间，第三连接部70位于换热器的第一侧部110，第三板片30与第四板片40通过第三连接部70连接，第三连接部70、第三板片30和第四板片40为一体结构，第三板片30与第四板片40之间具有第三流通通道5，第三板片30与第四板片40密封设置，第三板片30与第四板片40密封设置的区域至少围绕第三流通通道5以实现第三流通通道5周围的密封。第一板片10包括第二基部11和相对第二基部11凸出的第二凸部12，第二基部11围绕第二凸部12设置，第二板片20包括第一基部21和相对第一基部21凸出的第一凸部22，第二凸部12的凸出方向与第一凸部22的凸出方向相反，第一凸部22为环形，第一基部21包括第一内基部211和第一外基部212，第一凸部22围绕第一内基部211设置，第一外基部212围绕第一凸部22设置，第三板片30包括第三基部31和相对第三基部31凸出的第三凸部32，第三凸部32的凸出方向与第一凸部22的凸出方向相反，第三基部31围绕第三凸部32设置，第四板片40包括第四基部41和相对第四基部41凸出的第四凸部42，第四凸部42的凸出方向与第三凸部32的凸出方向相反，第四凸部42为环形，第四基部41包括第四内基部411和第四外基部412，第四凸部42围绕第四内基部411设置，第四外基部412围绕第四凸部42设置，第二基部11与第一外基部212密封设置，第一凸部22与第三凸部32密封设置，第三基部31与第四外基部412密封设置。第二凸部12设有朝向第二板片20凸出的第一凸起13，至少部分第一凸起13与第一内基部211抵接，第一内基部211设有朝向第三板片30凸出的第二凸起23，至少部分第二凸起23与第三凸部32抵接，第三凸部32具有朝向第四板片40凸出的第三凸起33，至少部分第三凸起33与第四内基部411抵接，第四基部41设有背离第三板片30凸出的第四凸起43。本实施例中，凸起的形状为长条形，长条形凸起与换热板片2的长度方向呈角度设置，当然，凸起的形状也可以为人字波或 者点波，例如为多个离散设置的圆形凸起，或多边形凸起等。需要指出的是，当换热器1仅具有第一板片10、第二板片20和第三板片30时，即换热器1仅具有第一流通通道3和第二流通通道4时，可以仅设置第一凸起13和第二凸起23，或者仅设置第二凸起23和第三凸起33，或者仅设置第二凸起23，当然，也可以在第二板片20设置朝向第一板片10凸出的凸起和朝向第三板片30凸出的凸起。
如图13所示，第一流通通道3或第二流通通道4可以不设置用于扰流的凸起，即第一板片10的第二凸部12不设置凸起，第二板片20位于第一凸部22内侧的第一内基部211不设置凸起，第三板片30的第三凸部32不设置凸起，第一流通通道3和第二流通通道4可以通过设置翅片来提升对换热流体的扰流，从而提升换热效果。当然，也可以仅在第一流通通道3或第二流通通道4通过板片设置凸起的方式实现扰流，在另一个通道通过设置翅片实现扰流。
在一些具体实施方式中，换热器1还包括第一角孔通道6、第二角孔通道7、第三角孔通道8和第四角孔通道9，第一流通通道3与第一角孔通道6和第二角孔通道7连通，第二流通通道4与第三角孔通道8和第四角孔通道9连通，第三流通通道5与第一角孔通道6和第二角孔通道7连通。当换热器1具有多个流通通道时，奇数层的流通通道与第一角孔通道6和第二角孔通道7连通，偶数层的流通通道与第三角孔通道8和第四角孔通道9连通。如图1-图12所示，每个换热板片2均具有第一角孔100、第二角孔200、第三角孔300和第四角孔400，其中，多个换热板片2的第一角孔100至少部分对齐形成第一角孔通道6，多个换热板片2的第二角孔200至少部分对齐形成第二角孔通道7，多个换热板片2的第三角孔300至少部分对齐形成第三角孔通道8，多个换热板片2的第四角孔400至少部分对齐形成第四角孔通道9，其中，第一角孔100和第二角孔200为圆形，第一角孔100和第二角孔200位于换热板片2的长度方向的两端，并且第一角孔100和第二角孔200靠近换热器1的第二侧部120，第三角孔300和第四角孔400为椭圆形，第三角孔300和第四角孔400位于换热器1的长度方向的两端，并且第三角孔300和第四角孔400靠近换热器1的第一侧部110，具体的，第一板片10设有朝向第二板片20凸出的两个第一凸 台部14，第一凸台部14的顶部与第二基部11位于同一平面，第一凸台部14的顶部设有第三角孔300或者第四角孔400，第一板片10的第一角孔100和第二角孔200位于第二凸部12，第二板片20设有朝向第三板片30凸出的两个第二凸台部24，第二凸台部24的顶部与第一凸部22的顶部位于同一平面，第二凸台部24的顶部设有第一角孔100或者第二角孔200，第二板片20的第三角孔300和第四角孔400位于第一内基部211，第三板片30设有第三凸台部34，具体结构同第一板片10，第四板片40设有第四凸台部44，具体结构同第二板片20，以此类推。第一板片10的第一角孔100和第二角孔200与第二板片20的第一角孔100和第二角孔200之间具有间隙实现第一流通通道3与第一角孔通道6和第二角孔通道7连通，第一板片10的第三角孔300或第四角孔400周围的第一凸台部14的顶部与第二板片20的第三角孔300或第四角孔400周围的第一内基部211密封设置，第二板片20的第一角孔100或第二角孔200周围的第二凸台部21的顶部与第三板片30的第一角孔100或第二角孔200周围的第三凸部32的顶部密封设置，第二板片20的第三角孔300和第四角孔400与第三板片30的第三角孔300和第四角孔400之间具有间隙实现第二流通通道4与第三角孔通道8和第四角孔通道9连通。
当然，部分换热板片2也可以仅具有两个角孔或者三个角孔或者五个角孔等，角孔的不同数量可以实现流通通道的不同流程的设置。角孔的形状也可以相同，例如都为圆形。
