Barrel-shaped component as well as vessel and motor housing based on it

Abstract

Disclosed is a barrel-shaped component and a container and an electric motor housing based thereon. The barrel-shaped component comprises a hollow metal pipe ( 11 ), wherein two ends of the hollow metal pipe ( 11 ) are respectively provided with an inlet ( 12 ) and an outlet ( 13 ). The hollow metal pipe ( 11 ) continuously spirals around an axis to form a plurality of annular components ( 14 ) arranged in parallel, wherein the annular components ( 14 ) are welded and fixed to each other. A component of any shape and size can be processed by using a simple elbow mould, thereby improving the cooling effect, lowering the processing cost and the material cost, and increasing the rigidity of the whole component where the barrel has the same wall thickness.
