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

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention is related to a component, in particular to a barrel-shaped component and a vessel and motor housing based on it. 
     2. Description of Related Art 
     In most cases, existing barrel-shaped components are used in a cooling and heating occasion. For instance, motor housing normally requires cooling. Many vessels used to collect liquids also require to be heated and cooled. Present structure falls into the following several types. Firstly, shaped materials are used for processing; however, only straight pipeline can be formed. However, complicated water line structure and high cost may affect the rigidity of the housing. Secondly, the submerged tube is used for processing; in other words, the cooling tube is embedded into the motor housing wall. However, such processing technique is so complicated, which requires higher investment in moulds. Thirdly, sleeve-connected process is used; in other words, the motor housing is divided into internal and external housings, and a cooling tube is provided between the two housings. However, such structure has disadvantages of poor rigidity and higher cost. 
     SUMMARY OF THE INVENTION 
     The technical issue to be solved by the present invention is to provide a barrel-shaped component, as well as a vessel housing and a motor housing based on it, featuring in easy processing, low cost, high rigidity and excellent cooling effect. 
     Technical solution used by the present invention to solve aforesaid technical issue is a barrel-shaped component comprising a hollowed metallic tube; both ends of the hollowed metallic tube are provided with an inlet and an outlet respectively; the hollowed metallic tube continuously circles around an axis to form numerous parallel annular components; the annular components are fixed through welding. 
     The annular components are fixed through welding on intermittent welding points. 
     A gap is reserved among the annular components. 
     The annular components are fixed through welding on a continuous welding layer. 
     The annular components are circular components. 
     The annular components are polygonal annular components. 
     The cross section of the hollowed metallic tube is in a shape of a circle or a polygon. 
     Aforesaid barrel-shaped component serves as the cylinder of a vessel; both ends of the cylinder are provided with a base plate and an end cover, respectively. When it is used as a vessel, there should be no gap among numerous parallel annular components formed by the hollowed metallic tube continuously circling around the axis. 
     Aforesaid barrel-shaped component can also constitute a motor housing through providing an end cover on each of the two ends respectively. In such case, the barrel-shaped component is used as the motor housing body. 
     As compared with prior arts, the advantage of the present invention lies in the fact that it makes use of a hollowed tube to form numerous parallel annular components through circling. Furthermore, adjacent annular components are welded, connected and fixed to form a big barrel-shaped component. Not only the cooling effect is significantly improved, but also the processing is easy, and the costs of processing and materials are reduced. Meanwhile, as compared with prior arts, rigidity of the whole component can be improved when the cylinder wall thickness remains unchanged. The present invention is available for processing of components of any form and size with help of simple bending molds. The barrel-shaped component according to the present invention can be used as the cylinder of the vessel and motor housing. When the barrel-shaped component is used as the motor housing, it can fix adjacent annular components through welding on the intermittent welding points for saving processing cost. Moreover, the gaps provided can also improve heat dissipation effect of the motor housing. When the barrel-shaped component is used as the cylinder of the vessel for collecting liquids, the annular component can be sealed through welding on the continuous welding layer.
