Benefits of technology

This solution enables efficient assembly, reduced weight, improved durability, and enhanced cooling efficiency, while allowing for modular design and cost-effective production, addressing the limitations of conventional methods by simplifying the assembly process and reducing the risk of fluid leakage.

Problems solved by technology

Thus, portions which will give excess weight remain, posing problems about weight reduction and downsizing of the integrated piping plate.
In order for the grooves to function as channels for fluids, there is need for the step of performing surface treatment of the groove portions, but this is not a method suitable for mass production.
This results in a low work efficiency, and is not very suitable for mass production.
The bolts for fixing of the plates impede the downsizing of the integrated piping plate.
Thus, even when the fluid flowing through the grooves is to be cooled via the plate, it is difficult to raise the cooling efficiency.

embodiment 1

[0300] [Embodiment 1]

[0301] Details of the configuration of an integrated piping plate according to an embodiment of the present invention will be described based on FIG. 1, with a fuel cell power generation system taken as an example.

[0302] As shown in FIG. 1, an integrated piping plate 1 comprises a plate 2 and a plate 3 joined by a suitable adhesive 4. The integrated piping plate 1 is constituted by fixing constituent instruments and components of a fuel cell power generation system (indicated by one-dot chain lines in FIG. 1), which are disposed on a surface (upper surface in FIG. 1) 3a of the plate 3 and include a constituent instrument 5, by stud bolts 6 and nuts 7 integrally with the plates 2, 3.

[0303] In a joining surface (an upper surface in FIG. 1) of the plate 2 to be joined to the plate 3, grooves 8 are formed, the grooves 8 having predetermined sectional area suitable for the velocities of corresponding fluids and having suitable lengths and directions adapted for the...

embodiment 2

[0390] [Embodiment 2]

[0391] A machining method for an integrated piping plate 201 according to the present embodiment will be described based on FIGS. 40A, 40B and 40C. As shown in FIGS. 40A, 40B and 40C, when a plate 202 and a plate 203 are to be joined for integration, the first step is to superpose the plate 202 and the plate 203. In the plate 202, a groove 208 to serve as a channel for a fluid (liquid or gas) has been machined. In the plate 203, communication holes 210 as a communication between the fluid channel groove 208 and instruments or components constituting an apparatus, such as a fuel cell power generation system, have been machined. In this superposed state, a groove 221 to serve as a weld groove is machined in the plate 203 so as to extend along the entire periphery of the fluid channel groove 208. Then, this groove 221 for the weld groove is welded.

[0392] The fluid channel groove 208 is not restricted to a joining surface 202a of the plate 202, but may be formed in...

embodiment 3

[0423] [Embodiment 3]

[0424]FIG. 45A shows a plate 302 produced by forming depressions (hereinafter referred to as grooves 301) of predetermined shapes, which serve as fluid channels, as a result of press working of an aluminum plate or an aluminum alloy plate.

[0425] Press working is performed by plastic working a metal plate of a highly plastic metallic material under pressure with the use of a mold having an arbitrary shape. This is a machining technique with dimensional accuracy and excellent volume productivity. This technique can select a corrosion resistant material as an object to be machined.

[0426]FIG. 45B is a cross sectional view taken on line A1-A1 of the plate 302 in FIG. 45A.

[0427] As shown in FIG. 45B, the cross sectional shape of the groove 301 is a rectangular depression having a suitable width L2 and a suitable depth H2. For easy press working, a corner 301a has suitable roundness R, and a side wall portion 301b of the groove 301 is suitably inclined.

Abstract

A machining method for an integrated piping plate, for example, composed of a plurality of plates joined together, and in which an instrument and a component constituting an apparatus, or the instrument, or the component are or is disposed on one surface or both surfaces of the integrated piping plate, and the instrument and the component, or the instrument, or the component are or is connected by fluid channel grooves formed in joining surfaces of the plates, and communication holes formed in the plates. The machining method welds the joining surfaces of the plates around the entire periphery of the fluid channel grooves, for example, by an FSW welding machine, to join the plates. Compared with joining of the plates by an adhesive, the machining method can increase the durability of the plate joining portion and increase pressure resistance.
