Description

  The present invention relates to a fixed-type unit in which piping, wiring, etc. are integrated into a device and integrated into a compact unit or an integrated unit that can be assembled and transported. For example, it can be installed in a bent narrow space. The present invention relates to a flexible bend base with a built-in passage.

  In recent years, in other industrial fields such as in-vehicle fuel cell devices and fluid control devices, pipes, wiring, etc. are incorporated into the device to be a compact unit and a unit that can be assembled and transported. In addition, a passage built-in base is often used.

FIG. 7 shows a schematic configuration of a conventional passage built-in base.
The passage built-in pedestal 51 joins a flat upper plate 52 and a lower plate 53 by an appropriate method such as a friction stir welding method, and a device 55 or a component 55 ′ (see FIG. 7) arranged on the upper plate 52. Is shown as a single-dot chain line) together with the upper plate 52 and the lower plate 53, and is integrally fixed with bolts 59, nuts 60, and the like. A communication hole 54 is formed at an appropriate position of the upper plate 52 immediately below the device 55 and the like, and a groove 57 having a predetermined cross-sectional area and an appropriate length and direction is formed on the upper surface of the lower plate 53. The communication hole 54 and the groove 57 are arranged so as to communicate with each other. The communication holes 54 and the grooves 57 allow the devices 55 and the like disposed on the upper plate 52 to communicate with each other to supply pipe passages, signals, and electric power through which liquids and gases necessary for the system configuration flow. It will be responsible for the function of the wiring path to do. The cross-sectional areas of the communication hole 54 and the groove 57 are determined from the properties of the flowing liquid, the flow velocity, the pressure loss, and the like, and the length and direction thereof are determined by the arrangement of components such as the device 55 arranged on the upper plate 52. It is determined.

  As the material of the upper plate 52 and the lower plate 53, an aluminum plate is usually used because of its reduced weight for movement and the ease of forming and joining the grooves 57. In some cases, steel plates or cast products are used. In addition, as a method of joining the upper plate 52 and the lower plate 53, the friction stir welding method is exclusively employed from the viewpoint of the strength and reliability of the joint, and the fluid is used at a relatively low temperature or low pressure. In some cases, a bonding method using a thermosetting adhesive or a room temperature curable adhesive is also employed.

The pedestal 51 with built-in passage as shown in FIG. 7 can store all complicated piping and wiring inside the upper plate 52 and the lower plate 53, so it can be integrated compactly and is convenient for transportation and the like. The field of use is expanding.
