具体实施方式
下面结合附图和实施例对本实用新型进行详细描述。
实施例1：

Y字型涡流发生器401的梯形截面高度H为2～4mm，梯形截面上部宽度A和下部宽度B均为2～6mm。

左上分支401a长度L 1为26mm，右上分支401b长度L 2为26mm，下分支401c长度L 3为20mm。

首尾两个单元外片300与相邻的中间单元片400之间以及两相邻的中间单元片400之间的间距S 4为50mm。
实施例3：

Figure PCTCN2018104475-appb-000002
由于参数选择原因，计算机计算与实际情况存在一定误差，但Y字型片散散热效果目前还是最佳。
本实用新型片式散热器ONAN散热容量提高10％-20％以上，相同容量的变压器选用本实用新型可减少组数或片数，减少片散占用变压器横向体积，为大型电力变压器选用冷却装置提供更大空间，降低成本。
