It is further preferred that be the open notch in side when the passage of heat is located on the edge of the bending part, it is described
It is through-hole when passage of heat is located on the inside of the edge of the bending part.
It is further preferred that the passage of heat includes multiple notches, multiple on the same bending part
The cross-sectional shape of the notch is the combination of same shape or various shapes.
It is further preferred that the passage of heat includes multiple through-holes, multiple on the same bending part
The cross-sectional shape of the through-hole is the combination of same shape or various shapes.
It is further preferred that on the same bending part, the passage of heat includes multiple notches and more
The cross-sectional shape of a through-hole, multiple notches is the combination of same shape or various shapes, multiple described logical
The cross-sectional shape in hole is the combination of same shape or various shapes.
More preferably, the cross-sectional shape of multiple notches be selected from " u "-shaped, " V " shape, " W " shape, Y-shaped, rectangle its
In one or more combination.
More preferably, the cross-sectional shape of multiple through-holes is selected from circle, triangle, diamond shape, heart, water-drop-shaped, five
The combination of the star-shaped one or more of them in angle.
Compared to the prior art, transformer framework of the invention uses the stitch including bending part, can effectively clamping line
The lead-out wire of circle, and the passage of heat in bending part can accelerate wicking speed and heat transfer, the insulation in rope-lay strand
Layer easily fusing, tin layers area coverage is more, and tin welding is secured.
