一种锯齿形错列翅片冷却器
摘要：
本发明提出了一种锯齿形错列翅片冷却器，包括壳体，所述的壳体包含有若干列齿形结构；所述若干列齿形结构分为奇数列齿形结构与偶数列齿形结构，所述奇数列齿形结构与偶数列齿形结构呈交错排列，奇数列的齿形结构与偶数列的齿间结构相对。本发明的优点是：横向翅片间距小，增加了湍流效果，加强了换热条件，使得换热更为均匀，同时，相同距离情况下翅片数量大，流动阻碍增多，出入口两端压降增大，而油液换热面面积增大，使得换热能力进一步上升。
摘要（英）：

The invention provides a zigzag staggered finned cooler which comprises a shell. A plurality of columns of toothed structures are included in the shell and are divided into an odd number of columns of toothed structures and an even number of columns of toothed structures, wherein an odd number of columns of toothed structures and an even number of columns of toothed structures are arranged in a staggered manner, and teeth of the odd number of columns of toothed structures and teeth of the even number of columns of toothed structures are opposite. The zigzag staggered finned cooler has the advantages that the distance between transverse fins is small, a turbulence effect is improved, heat exchange conditions are improved, and heat exchange is more even; meanwhile, the number of fins is large under the condition of the same distance, flow obstacles are increased, the pressure drop at the two ends of an outlet and inlet opening is increased, the area of an oil heat exchange area is enlarged, and therefore the heat exchange capability is further improved.
