  Various specific examples of the configuration of the channel-embedded pedestal have already been proposed. For example, the configuration disclosed in the following [Patent Document 1] can be given. Here, based on FIG. 7, FIG. 8 (a) and FIG. 8 (b), the structural example of the conventional flow-path built-in type base is demonstrated.

JP 2002-305010 A Japanese Patent No. 2792233

  As described above, the cross-sectional area of the groove (built-in flow path) is determined from the properties of the fluid flowing in the groove, the flow velocity, the pressure loss, and the like. When the fluid is caused to flow with a low pressure loss, it is necessary to increase the cross-sectional area of the groove (built-in channel). On the other hand, the pressure is transmitted as in the case of control of equipment using pressurized air, but the cross-sectional area of the groove (built-in flow path) may be small when the flow rate may be small.

  In addition, when working fluid such as pressurized air or pressurized oil is divided from the main flow path to a plurality of branch flow paths to operate each cylinder or each valve, a groove (built-in flow path) ) Requires a large flow of working fluid, so the cross-sectional area must be increased. On the other hand, the groove (built-in flow path) that serves as the branch flow path only needs to flow a small flow of working fluid. The area may be reduced.

  And, when applying a built-in channel type pedestal to a system in which large-diameter pipes with a very large diameter compared to other pipes are mixed in this way, The large-diameter pipe is also replaced with a groove (built-in channel).

  For this reason, for example, as shown in FIG. 9, the lower plate 3 has a large cross-sectional groove 7A (built-in channel) that functions as the large-diameter pipe and a small cross-sectional groove 7B that functions as the other pipe. (Built-in flow path) must be formed. Therefore, in this case, it is necessary to increase the thickness h of the entire lower plate 3 in order to ensure a large cross-sectional area of some of the grooves 7A. For this reason, there are many useless parts in the lower plate 3, and the flow path built-in pedestal 1 constituted by the lower plate 3 is also large and heavy.

  Therefore, in this case, the entire unit of the fixed unit and the movable unit is hindered from being made compact and lightweight, and it has been difficult to reduce the installation space and improve the ease of transportation.

  FIG. 10 shows a configuration example of a system in which a tank 11 for storing pressurized air or the like is present as a component device.

  In this system, a frame 13 is fixed on a gantry 12, and a tank 11 is attached to the frame 13. Even when the pedestal with a built-in channel is applied to such a system, if not only the piping but also the tank 11 is replaced with a groove (built-in channel), a groove (built-in channel) having a very large cross-sectional area is formed. The plate needs to be formed, and the thickness of the entire plate becomes too large. For this reason, the same problem as described above occurs, and the manufacture is also difficult.

  Therefore, in view of the above circumstances, the present invention has a built-in flow path that can be provided with a hollow structure part that functions as a large-diameter pipe or a tank without increasing the thickness of the flat plate constituting the built-in flow path type pedestal. An object is to provide a mold base.

The channel-embedded pedestal of the first invention that solves the above problems is formed by joining a plurality of flat plates, and a groove formed on at least one of the flat plates is formed as a fluid. In the built-in channel type pedestal in which the device is mounted on the surface of the pedestal on one side or both sides.
By joining the bent plate to the pedestal surface on one or both sides, at least the hollow structure portion in the thickness direction of the flat plate is larger than the dimension in the thickness direction of the groove on the one or both sides. It is formed on the pedestal surface.

The bent plate is a flow path member, and the hollow structure portion is a fluid flow path.

Further, the channel-embedded pedestal of the third invention is the channel-embedded pedestal of the first invention,
The bent plate is a tank member, and the hollow structure portion is a tank for storing a fluid.

Further, the channel-embedded pedestal of the fourth invention is the channel-embedded pedestal of the third invention,
The tank members are joined to the pedestal surfaces on both sides, the tanks are formed on the pedestal surfaces on both sides, and these tanks are communicated with each other through a communication hole penetrating the flat plate in the thickness direction. Therefore, it is characterized by being integrated.

  According to the channel-embedded pedestal of the first invention, a plurality of flat plates are joined together, and a groove formed on at least one joining surface of the flat plates is formed as a fluid flow passage. In the pedestal with a built-in flow path in which a device is mounted on the surface of one or both sides of the pedestal, and at least the dimension in the thickness direction of the flat plate plate is joined to the surface of the pedestal on one or both sides. Is formed on the surface of the pedestal on one side or both sides with a large hollow structure portion as compared with the dimension in the thickness direction of the groove. A hollow structure with a large cross-sectional area (at least the dimension in the plate thickness direction is larger than the groove (built-in channel)) that functions as a pipe, tank, or storage unit. It can be provided to.

  Therefore, even when a fixed unit and a movable unit are configured by applying the pedestal with a built-in flow path of the present invention to a system that requires a large-diameter pipe, a tank, or a housing portion, the entire unit can be made compact and lightweight. Therefore, it is possible to reduce the installation space and improve the ease of transportation. Of course, this effect becomes more prominent as the difference between the cross-sectional area of the hollow structure portion (dimension in the plate thickness direction) and the cross-sectional area of the groove (built-in channel) (dimension in the plate thickness direction) increases.

  According to the channel-embedded pedestal of the second invention, in the channel-embedded pedestal of the first invention, the bent plate is a channel member, and the hollow structure portion is a fluid channel. Therefore, a large cross-sectional area (at least the dimension in the plate thickness direction is larger than the groove (internal flow path)) that functions as a large-diameter pipe without increasing the thickness of the entire flat plate. Can do.

  Therefore, even when a fixed unit or movable unit is configured by applying the pedestal with a built-in flow path of the present invention to a system in which large-diameter pipes are mixed, the entire unit can be made compact and lightweight. It is possible to reduce the installation space and improve the ease of transportation. Of course, such an effect becomes more prominent as the difference between the cross-sectional area of the flow path (dimension in the plate thickness direction) and the cross-sectional area of the groove (built-in flow path) (dimension in the plate thickness direction) increases.

  Further, according to the flow path built-in type pedestal of the third invention, in the flow path built-in type pedestal of the first invention, the bent plate is a tank member, and the hollow structure part is a tank for storing a fluid. Therefore, a tank having a large cross-sectional area (at least the dimension in the plate thickness direction is larger than that of the groove (built-in flow path)) can be provided without increasing the thickness of the entire flat plate.

  Therefore, even when a fixed unit or a movable unit is configured by applying the pedestal with a built-in channel according to the present invention to a system that requires a tank, the entire unit can be made compact and light, so that the installation space can be reduced. Can be reduced, and the ease of transportation can be improved. Of course, this effect becomes more prominent as the difference between the cross-sectional area of the tank (dimension in the plate thickness direction) and the cross-sectional area of the groove (built-in channel) (dimension in the plate thickness direction) increases.

  Further, according to the flow path built-in type pedestal of the fourth invention, in the flow path built-in type pedestal of the third invention, the tank member is joined to the surface of the pedestal on both sides, and the tank is formed on the surface of the pedestal on both sides. In addition, these tanks are integrated by connecting the flat plate plate with a communication hole penetrating in the thickness direction, so that the tanks on both sides are integrated into a large-capacity tank. Can be used as That is, a large-capacity tank can be provided on the channel-embedded pedestal without increasing the thickness of the entire flat plate.

  Embodiments of the present invention will be described below in detail with reference to the drawings.

<Embodiment 1>
FIG. 1 is a plan view showing a configuration of a channel built-in type pedestal according to Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view taken along line BB in FIG. 1, and FIG. 3 is a line CC in FIG. It is arrow sectional drawing.

  As shown in FIGS. 1, 2, and 3, the channel-embedded pedestal 21 is also referred to as a logic plate or an integrated pipe, and is an upper plate 22 that is a flat plate and a lower plate that is another flat plate. The plate 23 is joined by a joining means such as a friction stir welding method or an adhesive which is appropriately selected according to the required joining strength. On one surface (upper side in the illustrated example) of the channel-containing pedestal 21, that is, on the surface 22a of the upper plate 22, for example, various devices 54A such as parts and devices constituting a fuel cell power generation system, a fluid control system, etc. 54B is attached. That is, the flow path built-in base 21 functions as a base for mounting the devices 24A and 24B.

  The devices 24 </ b> A and 24 </ b> B include upper and lower plates 22 and 23 by through bolts 25 inserted into bolt holes 22 b and 23 a formed in the upper and lower plates 22 and 23 and nuts 26 screwed into the through bolts 25. And fixed to the base surface (upper plate surface 22a).

  A plurality of grooves 27 are formed on the joint surface 23b of the lower plate 23 by appropriate processing means such as an end mill, a milling machine, or a drilling machine. These grooves 27 have a predetermined cross-sectional area (area of a cross section perpendicular to the fluid flow direction: see FIG. 2), and are formed in an appropriate length and direction. The upper plate 22 is joined to the lower plate 23 so as to cover these grooves 27 (cover the grooves 27), thereby forming a fluid flow path. The cross-sectional area of each groove 27 is determined based on the properties of the fluid flowing in each groove 27, the flow velocity, the pressure loss, and the like, and the length and direction of each groove 27 are determined by the arrangement of each device 24A.

  However, there is no significant difference in the cross-sectional areas of these grooves 27. Furthermore, these grooves 27 are not significantly different in dimensions h1 and h2 in at least the thickness direction of the upper and lower plates 22 and 23 (vertical direction in FIG. 2; hereinafter, simply referred to as plate thickness direction). That is, in the first embodiment, only the flow path having a relatively small cross-sectional area (dimensions h1 and h2 in the plate thickness direction) and not so different is used as the built-in flow path by the groove 27 of the lower plate joint surface 23a. Forming. In other words, the lower plate 23 has a thickness that is thin enough to form a groove 27 (built-in channel) having a relatively small cross-sectional area (dimensions h1 and h2 in the plate thickness direction).

  A communication hole 29 is formed in the upper plate 22, and the groove 27 communicates with the device 24 </ b> A through these communication holes 29. That is, a plurality of grooves 27 are built in the flow path built-in pedestal 21 as fluid flow paths, and these grooves 27 (built-in flow paths) serve as piping for connecting the devices 24A. . That is, the flow path built-in base 21 also functions as an integrated pipe. Reference numeral 31 in the drawing denotes a sealing O-ring interposed between the devices 24A and 24B and the upper plate 22 (communication hole 29).

  And between the apparatus 24B which requires the flow path equivalent to large diameter piping, the flow path member 28 as a bending plate is joined to the predetermined position of the surface 23c of the lower plate 23 corresponding to this. The flow path member 28 is a bent plate having an appropriate thickness prepared separately from the upper and lower plates 22 and 23. By joining the flow path member 28 to the lower plate surface 23c, the flow path 30 is formed as a hollow structure portion having a larger cross-sectional area than the built-in flow path formed by the grooves 27. That is, the flow path 30 is not a built-in flow path formed on the plate joining surface, but a flow path formed on the pedestal surface (lower plate surface 23c).

  The flow path 30 has a cross-sectional area (fluid flow) compared to the built-in flow path formed by the groove 27 for the purpose of flowing a large flow rate fluid or flowing a highly viscous fluid with low pressure loss. The area of the cross section perpendicular to the direction (see FIG. 2) is very large. That is, the dimension h3 of the flow path 30 in the plate thickness direction is much larger than the dimensions h1 and h2 of the built-in flow path formed by the grooves 27 in the plate thickness direction.

  The flow path member 28 is a bent plate made of steel or aluminum whose cross-sectional shape is bent in a U shape as shown in FIG. Further, a flange portion 28 a that is a joint portion to the lower plate 23 is provided projecting outward from the peripheral edge portion of the flow path member 28.

  The flow path member 28 having such a shape can be manufactured by bending a plate having an appropriate thickness such as a steel plate or an aluminum plate by a processing means such as press working or by means such as casting. it can. Then, by joining the flange portion 28a of the flow path member 28 to the surface 23c of the lower plate 23 by a friction stir welding method, other welding means, or adhesion, a cross-sectional area that functions as a large-diameter pipe ( A large flow path 30 having a dimension h3) in the plate thickness direction is formed.

  The flange portion 28a of the flow path member 28 is joined to the lower plate 23 over the entire periphery thereof, and leakage of fluid flowing through the flow path 30 from the joint portion is prevented. The length and direction of the flow path 30, that is, the length and direction of the flow path member 28 are determined by the arrangement of the devices 24B.

  In addition, communication holes 29 are formed in the upper and lower plates 22 and 23, and the flow path 30 is connected to the device 24 </ b> B through these communication holes 29. The cross-sectional shape of the flow path member 28 is not necessarily limited to the U shape, and may be an arc shape such as a semicircular shape. Further, the flow path member 28 is not limited to the surface 23 c of the lower plate 23, and may be bonded to the surface 22 a of the upper plate 22.

  As described above, according to the flow path built-in type pedestal 21 of the first embodiment, the flow path member 28 is arranged on one pedestal surface (lower plate surface 23c or upper plate surface 22a) or on both pedestal surfaces (lower plate). By joining to the surface 23c and the upper plate surface 22a), that is, by joining the flow path member 28 to a place where a large-diameter pipe is required, the cross-sectional area (the dimension h3 in the plate thickness direction) becomes the groove 27 (built-in flow path). Since the flow path 30 larger than the cross sectional area (dimensions h1 and h2 in the plate thickness direction) is formed, it functions as a large-diameter pipe without increasing the thickness of the entire lower plate 23 or the entire thickness of the upper plate 22. A flow path 30 having a large cross-sectional area (the dimension h3 in the plate thickness direction is larger than the dimensions h1 and h3 in the plate thickness direction of the groove 27 (built-in flow path)) can be provided.

  Therefore, even when a fixed unit or movable unit is configured by applying the pedestal with a built-in flow path of the present invention to a system in which large-diameter pipes are mixed, the entire unit can be made compact and lightweight. It is possible to reduce the installation space and improve the ease of transportation. Of course, such an effect becomes more prominent as the difference between the cross-sectional area of the flow path 30 (dimension h3 in the plate thickness direction) and the cross-sectional area of the groove 27 (built-in flow path) (dimensions h1 and h2 in the plate thickness direction) increases. is there.

<Embodiment 2>
4 is a plan view showing a configuration of a channel built-in type pedestal according to Embodiment 2 of the present invention, and FIG. 5 is a cross-sectional view taken along line BB in FIG. FIG. 6 is a cross-sectional view showing another configuration of the tank portion in the flow path built-in pedestal.

  As shown in FIGS. 4 and 5, the flow path built-in pedestal 41 is also referred to as a logic plate or an integrated pipe, and includes an upper plate 42 that is a flat plate and a lower plate 43 that is another flat plate. They are joined by a friction stir welding method or a joining means such as an adhesive that is appropriately selected according to the required joining strength. On one surface (upper side in the illustrated example) of the flow path built-in base 41, that is, the surface 42a of the upper plate 42, various devices 44A such as components and devices constituting a fuel cell power generation system, a fluid control system, etc. 44B is attached. That is, the flow channel built-in type base 41 functions as a base for mounting the devices 44A and 44B.

  The devices 44A and 44B have upper and lower plates 42 and 43 by means of through bolts 45 inserted into bolt holes 42b and 43a formed in the upper and lower plates 42 and 43 and nuts 46 screwed into the through bolts 45, respectively. And fixed to the base surface (upper plate surface 42a).

  A plurality of grooves 47 are formed on the joint surface 43b of the lower plate 43 by appropriate processing means such as an end mill, a milling machine, or a drilling machine. These grooves 47 have a predetermined cross-sectional area (area of a cross section perpendicular to the fluid flow direction: see FIG. 5), and are formed in an appropriate length and direction. The upper plate 42 is joined to the lower plate 43 so as to cover these grooves 47 (cover the grooves 47), thereby forming a fluid flow path. The cross-sectional area of each groove 47 is determined based on the properties of the fluid flowing in each groove 47, the flow velocity, the pressure loss, and the like. The length and direction of each groove 47 are determined according to the devices 44A and 44B and the tank 48 (details will be described later). ).

  However, there is no great difference in the cross-sectional areas of these grooves 47. More specifically, these grooves 47 are not significantly different in dimensions h4 and h5 in at least the thickness direction of the upper and lower plates 42 and 43 (vertical direction in FIG. 5; hereinafter, simply referred to as plate thickness direction). In other words, the lower plate 43 has a thickness that is thin enough to form a groove 47 (built-in channel) having a relatively small cross-sectional area (dimensions h4 and h5 in the plate thickness direction).

  The tank 48 as a hollow structure portion having a larger cross-sectional area than these grooves 47 (built-in flow paths) is not formed by forming tank grooves on the plate joint surface, It is formed on the pedestal surface (upper plate surface 42 a) by a tank member 49 as a bent plate prepared separately from 43.

  A communication hole 50 is formed in the upper plate 42, and the groove 47 is communicated with the device 44 </ b> A and the tank 48 through these communication holes 50. The device 44B is also communicated with the groove 47 through the communication hole 50. That is, a plurality of grooves 47 are built in the flow path built-in pedestal 41 as fluid flow paths, and these grooves 47 (built-in flow paths) are pipes and equipment 44B connecting the equipment 44A and the tank 48. It serves as a pipe that connects them together. That is, the flow path built-in base 41 also functions as an integrated pipe. Reference numeral 51 in the figure denotes a sealing O-ring interposed between the device 44A and the upper plate 42 (communication hole 50).

  The tank 48 can be applied to various tanks such as a pressure accumulating tank that stores pressurized air, pressurized oil, and the like. For example, in order to secure a predetermined capacity, the tank 48 is compared with the flow path formed by the groove 57. The cross-sectional area (see FIG. 5) is very large. That is, the dimension h6 of the tank 48 in the plate thickness direction is much larger than the dimensions h4 and h5 of the built-in channel formed by the grooves 57 in the plate thickness direction.

  The tank member 49 is a bent plate made of steel or aluminum whose cross-sectional shape is bent in a U shape as shown in FIG. Further, a flange portion 49 a that is a joint portion to the lower plate 23 is provided on the peripheral edge portion of the tank member 49 so as to protrude outward.

  The tank member 49 having such a shape can be manufactured, for example, by bending a plate having an appropriate thickness such as a steel plate or an aluminum plate by a processing means such as press working, or by means such as casting. . The cross-sectional shape of the tank member 49 is not necessarily limited to the U shape, and may be an arc shape such as a semicircular shape. Then, the flange portion 49a of the tank member 49 is joined to the surface 42a of the upper plate 42 by a friction stir welding method, other welding means, an adhesive, or the like, so that a cross-sectional area (a dimension h6 in the plate thickness direction) is obtained. A large tank 48 is formed.

  The flange portion 48a of the tank 48 is joined to the upper plate 42 over the entire circumference thereof, and leakage of fluid (gas or liquid) stored in the tank 48 from the joined portion is prevented. The cross-sectional area and length of the tank 48, that is, the cross-sectional area and length of the tank member 49 are determined by the capacity of the tank 48 and the like.

  A communication hole 50 is formed in the upper plate 42, and the tank 48 and the groove 47 (built-in flow path) communicate with each other through the communication hole 50. The groove 47 (built-in flow path) functions as a discharge pipe for discharging a fluid such as air or oil from the tank 48, and supplies the fluid to the tank 48 on the side of the tank 48 (tank member 49). For this purpose, a supply pipe 52 is connected. However, the present invention is not limited to this, and a general pipe may be used as the discharge pipe, or a built-in channel formed by a groove may function as the supply pipe.

  Further, in FIG. 5, the tank member 49 is joined to only one pedestal surface (the surface 42 a of the upper plate 42) to form the tank 48, but the present invention is not limited thereto, and the other pedestal surface (the surface of the lower plate 43). 43c) may be formed by joining the tank member 49 to form the tank 48. Furthermore, as shown in FIG. 6, the tank member 49 may be joined to the pedestal surfaces on both sides to form the tank 41.

  In FIG. 6, the tank member 41 is joined to the surface 42 a of the upper plate 42 and the surface 43 c of the lower plate 43 to form the tank 41, and these tanks 41 have the plate thicknesses of the upper and lower plates 42, 43. They are communicated with each other by a communication hole 50 penetrating in the direction. As a result, the upper and lower tanks 41 can be used as an integrated large-capacity tank. The upper and lower tanks 41 and the groove 47 (flow path) are communicated with each other through a communication hole 50.

  When the upper and lower tanks 41 are used as separate tanks, the upper and lower tanks 41 are separated without being communicated by the communication hole 50. In this case, a built-in flow path that functions as a supply pipe or a supply pipe and a built-in flow path that functions as a discharge pipe or a discharge pipe may be provided for each tank 41. The other configurations in FIG. 6 are the same as the configurations in FIGS. 4 and 5, and thus description thereof is omitted here.

  As described above, according to the channel built-in type pedestal 41 of the second embodiment, the tank member 49 is placed on one pedestal surface (upper plate surface 42a or lower plate surface 43c) or on both pedestal surfaces (upper plate surface). 42a and the lower plate surface 43c), that is, by joining the tank member 49 to the place where the tank is required, the cross-sectional area (dimension h6 in the plate thickness direction) becomes the cross-sectional area of the groove 27 (built-in flow path) ( Since the tank 48 larger than the plate thickness direction dimensions h4 and h5) is formed, the cross-sectional area is large (dimension in the plate thickness direction) without increasing the thickness of the entire upper plate 22 or the entire thickness of the lower plate 23. A tank 48 in which h6 is larger than dimensions h4 and h5 in the plate thickness direction of the groove 27 (built-in flow path) can be provided.

The present invention can also be applied to a flow path built-in base in which grooves are formed in the joint surfaces 23b and 43b.

  In the first and second embodiments described above, the flow path built-in bases 21 and 41 formed by joining two flat plates (upper and lower plates 22 and 23 and upper and lower plates 42 and 43) will be described as an example. However, the present invention is not limited to this, and the present invention can also be applied to a pedestal with a built-in channel formed by joining three or more flat plates. In this case, a groove may be formed on the joining surface of any flat plate.

  Further, the present invention is applied to the case where the flow path 30 serving as a large-diameter pipe and the tank 48 are provided as a hollow structure portion like the flow path built-in bases 21 and 41 of the first and second embodiments. Although it is useful, it is not necessarily limited to this, and the present invention can also be applied to a case where a hollow structure portion for other uses is provided on a channel-embedded base. For example, the present invention can also be applied to a case where a hollow structure portion that functions as a housing portion for various devices such as electronic components and control devices is provided on the channel-integrated base.
