Embodiment Construction
[0031] The invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, but the present invention is not limited to the following examples.
[0032] refer to figure 1 , a high-performance turbulence structure in array impingement jet cooling, comprising a jet orifice 1 and a jet target 3, the jet orifice 1 is provided with a plurality of impingement holes 2 arranged in an array; the jet orifice 1 is located in the The upper part of the jet target plate 3 is designed as a cavity between the two, and the spoiler column 4 is arranged on the jet target plate 3 , and the upper end of the spoiler column 4 is in contact with the jet orifice plate 1 . In this solution, the diameter of the impact hole 2 is set as D.
[0033] The spoiler column 4 is a column with a different pentagonal section, or a column with a nearly semi-elliptical dome-shaped section, or a column with a drop-shaped section.
[0034] As a scheme improveme...
