JP 2012-141115 A

  However, in the conventional fluid piping built-in component, there is a limit to the shape in which the pipe can be bent, and it has been impossible to form a fluid piping having a complicated planar shape. For example, a fluid pipe having a planar shape including one or more bends smaller than 90 ° could not be formed.

An object of the present invention is to provide a method of manufacturing a fluid pipe for use in the complex process of manufacturing a fluid pipe internal components of the fluid piping can be formed of shape, and fluid piping internal components.

Another object of the present invention is to provide a method of manufacturing a fluid pipe using fluid method for manufacturing a fluid pipe built-in part can flow smoothly in the fluid pipe, and the fluid piping internal components.

  The fluid piping built-in component to be improved by the present invention includes a base and a fluid piping. The base is made of a material that is corrosive to a fluid. The fluid piping is formed of a metal material having corrosion resistance to the fluid, and is embedded in the base so as to extend along a virtual plane imaginary in the base. And the planar shape of the fluid piping viewed from the direction orthogonal to the virtual plane includes one or more bends smaller than 90 °. In this invention, fluid piping is comprised from the 1st pipe | tube structural member and the 2nd pipe | tube structural member. The first pipe component member includes a groove that extends along the above-described virtual plane and has an opening that opens at least in one direction orthogonal to the virtual plane, and further has the same planar shape as the planar shape of the fluid piping. ing. The second pipe constituent member is composed of a second pipe constituent member joined to the first pipe constituent member so as to close the opening of the groove.

  As in the present invention, when the fluid pipe is constituted by the first pipe constituent member and the second pipe constituent member, the fluid pipe having corrosion resistance including a bending angle smaller than 90 ° which cannot be formed by bending is provided. Fluid piping built-in components can be easily obtained.

  The base can be configured by combining the first and second divided bases configured such that the mating surface extends along the virtual plane. In this case, a fitting groove into which at least a part of the fluid piping is fitted is formed in at least one of the first and second divided bases. In this way, the fluid piping can be easily arranged inside the base.

  It is desirable that the surface of the portion facing the groove in the joint portion between the first tube component member and the second tube component member has a curved surface having no corners. In this way, the fluid can flow smoothly into the fluid piping.

  In order to form such a curved surface, for example, the first pipe constituent member and the second pipe constituent member may be joined by welding. If it does in this way, the surface of the part which faces the groove | channel of the welding part made in the junction part of a 1st pipe | tube structural member and a 2nd pipe | tube structural member turns into a curved surface. Therefore, the surface of the part facing the groove of the joint portion between the first tube component member and the second tube component member can be easily formed into a curved surface. Further, if the first pipe constituent member and the second pipe constituent member are joined by welding, there is no gap between the first pipe constituent member and the second pipe constituent member, and the base is made of fluid. It can prevent corrosion.

  Various shapes can be adopted as the contour shape of the cross section of the fluid piping. For example, if the outline shape is a quadrangle, the first tube constituent member may be a U shape and the second tube constituent member may be a flat plate shape, and the first and second tube constituent members can be made simple. .

According to the method for manufacturing a fluid pipe built-in component of the present invention, the first pipe component member is subjected to cutting processing on a plate material formed of a metal material having corrosion resistance to the fluid to form a groove, The plate material can be formed by cutting the plate material to form a planar shape. Alternatively, the plate material may be cut to form a planar shape and then the cut plate material may be cut to form a groove. Thus, if a board | plate material is cut and cut and a 1st pipe | tube structural member is formed, the fluid piping of a complicated planar shape can also be formed. For example, a fluid pipe including one or more bends smaller than 90 ° can be formed accurately and easily.

  When aluminum or an aluminum alloy is used as the corrosive material, stainless steel, titanium, a titanium alloy, nickel, a nickel-base alloy, or copper can be used as the metal having corrosion resistance. In this way, corrosion of the base can be prevented due to the high corrosion resistance of the fluid piping.

  The fluid piping used for the fluid piping built-in component of the present invention can be manufactured as follows. First. The first tube constituent member is cut to a plate material made of a metal material having corrosion resistance against a fluid to form a groove, and then the plate material is cut to form a planar shape. Thereafter, the second pipe constituent member is joined to the first pipe constituent member. Alternatively, the plate material may be cut to form a planar shape, and then the cut plate material may be cut to form a groove to form the first tube constituent member. In this way, a complicated planar fluid pipe including one or more bends smaller than 90 ° can be formed accurately and easily by cutting and cutting the plate material.
