Embodiment Construction
[0018] Examples such as figure 1 As shown, an oil-immersed transformer cooling device includes an oil-immersed transformer heat sink 1, the length H of the oil-immersed transformer heat sink 1 is 800mm, and the width W is 480mm; the oil-immersed transformer heat sink 1 is stamped There are several three-dimensional convex spoiler structures.
[0019] Several three-dimensional protruding spoiler structures are arranged in a staggered manner at a certain distance, the horizontal spacing S1 is 80 mm, and the longitudinal spacing S2 is 40 mm.
[0020] The distance a between the first row of three-dimensional protruding spoiler structures and the bottom of the heat sink of the oil-immersed transformer is 240mm.
[0021] The three-dimensional protruding spoiler structure is a triangular conical longitudinal vortex generator 2 .
[0022] Such as figure 2 , image 3 As shown, the height d of the triangular conical longitudinal vortex generator 2 is 10 mm, and the angle of attack ...
