(First embodiment)
A structure 10 having a panel cooling system (panel ventilation system) 20 according to a first embodiment will be described using FIGS. 1 to 7. FIG.

FIG. 1 shows a structure 10 having a board cooling system 20. As shown in FIG. The structure 10 has a frame floor (bottom floor) 12, a frame ceiling 14, and a plurality of frame walls 16 between the frame floor 12 and the frame ceiling 14, and forms a space 18 therebetween. In this embodiment, it is preferable that the space 18 of the structure 10 can be closed/opened as appropriate using a door (not shown) or the like. An example of the structure 10 is a container in which the panel cooling system 20 is installed. Another example of the structure 10 is a factory, a building, etc. in which the panel cooling system 20 is placed.

The panel cooling system 20 according to this embodiment includes a floor chamber 22, a ceiling side chamber (ceiling ventilation chamber) 24, a plurality of panels 26, and an air conditioner 28.

The floor chamber 22 includes a floor plate portion 42 that cooperates with the frame floor 12 and the frame wall 16 to form the floor chamber 22, and a first channel (air outlet) 44 provided in the floor plate portion 42. Inside the floor chamber 22, wiring and piping (not shown) are arranged.

The floor plate portion 42 is arranged above, away from the frame floor 12, parallel to the upper surface of the frame floor 12, for example.

In this embodiment, an example will be described in which the floor plate portion 42 is arranged such that a floor plate 42a having a first channel 44 and a floor plate 42b having no first channel 44 are arranged side by side. The floor plate portion 42 may not be divided into floor plates 42a and 42b, but may be a single plate.

Although it is preferable that the floor plates 42a and 42b have the same shape and size, it is also preferable that they have different shapes and sizes. In this embodiment, each floorboard 42a, 42b is formed, for example, in a square shape and the same size. Each of the floor plates 42a and 42b is supported by, for example, support legs (not shown) fixed to the frame floor 12. A column (not shown) supported by the frame floor 12 may be attached to the back surface of each floor plate 42a, 42b.

Among the plurality of floorboards 42a and 42b, the floorboard 42a on which the first channel 44 is provided is arranged at a position where the board 26 is desired to be placed. That is, a first channel 44 is formed in a floor plate 42a that is a part of the floor plate portion 42. The first channel 44 communicates the upper side and the lower side of the floorboard section 42 . The first channel 44 is formed in an appropriate shape, such as a rectangular shape or a circular shape. In this embodiment, an example will be described in which the first channel 44 has a rectangular opening edge.

It is preferable that the arrangement of the floor plate 42a having the first channel 44 and the floor plate 42b having no first channel 44 can be changed as appropriate. It is preferable that the floorboards 42a having the first channels 44 are arranged at appropriate intervals, for example. The number of floor plates 42a having first channels 44 is equal to or greater than the number of boards 26. Note that FIG. 1 shows an example in which a floor plate 42a having a first channel 44 and a floor plate 42b having no first channel 44 are alternately arranged along the lateral direction in FIG.

For example, one box-shaped board 26 is installed so as to cover the first channel 44 of one floorboard 42a. The board 26 is made of, for example, a metal material. It is also preferable that the board 26 be disposed astride a floor plate 42a having the first channel 44 and a floor plate 42b not having the first channel 44, as shown in FIG. It is also preferable that the bottom of the board 26 be arranged inside the outer edge of the floorboard 42a on which the board 26 is installed. The board 26 is formed, for example, as a free-standing type having a rectangular parallelepiped shape.

As shown in FIG. 2, the board 26 includes a channel base (bottom) 52, a box body 54, and a door 56.

As shown in FIGS. 1 and 2, the channel base 52 is formed in an annular shape so as to surround the outer edge of the first channel 44 of the floor plate 42a, and is fixed to the floor plate 42a and the floor plate 42b on which the board 26 is placed. . In this embodiment, the channel base 52 is formed, for example, in a rectangular ring shape.

The box body 54 is fixed to the upper side of the rectangular annular channel base 52. The box body 54 is formed into a substantially rectangular parallelepiped shape. A door 56, such as a hinged door type or a double door type, is attached to the opening of the box body 54, for example. Note that various devices having parts that generate heat when energized, for example, are installed inside the box 54. The door 56 can be opened and closed with respect to the box body 54. Therefore, the various devices inside the box body 54 are installed in a state where they can be easily attached/detached and maintained. In this embodiment, the box body 54 is preferably formed at a height of, for example, within 2 m, which makes it easy for an operator to perform maintenance on various devices arranged on the panel 26.

The inside of the box 54 and the floor chamber 22 below the floor plate 42a are communicated through the first channel 44 and the channel base 52. The first channel 44 not only allows communication between the inside of the box 54 and the floor chamber 22 below the floor plate 42a, but is also used as a passage for wiring and piping. Note that the passage through which the wiring and piping passes and the first channel 44 may be formed separately.

The plate 26 is provided with an opening edge 58 as a second channel. The opening edge 58 forms a through hole that communicates the inside and outside of the box body 54. The opening edge 58 as the second channel is provided on, for example, the top plate 54a of the box body 54. The opening edge 58 is formed into an appropriate shape, such as a rectangular shape or a circular shape. The opening edge 58 not only communicates the inside and outside of the box body 54, but is also used as a passage for wiring and piping. Note that the passage through which the wiring and piping pass and the opening edge 58 may be formed separately.

The ceiling-side chamber 24 includes a ceiling plate 62 that cooperates with the frame ceiling 14 and the frame wall 16 to form the ceiling-side chamber 24, and a third channel 64 provided in the ceiling plate 62. Wiring and piping (not shown) are arranged inside the ceiling-side chamber 24.

The ceiling plate 62 is supported by a support portion (not shown) fixed to the ceiling frame 14. The ceiling plate 62 is disposed below, spaced apart from the ceiling frame 14, and parallel to the lower surface of the ceiling frame 14, for example. Like the floor plates 42a and 42b of the floor plate portion 42, the ceiling plate 62 may be formed by arranging a plurality of rectangular plates, or may be a single plate. In this embodiment, an example in which the ceiling plate 62 is a single plate will be described.

Note that the distance between the floor plate portion 42 and the ceiling plate 62 is preferably a distance that allows the operator to move easily. Further, it is preferable that the distance between each panel 26 is such that the operator can easily work by opening the door 56 of the panel 26.

As shown in FIG. 1, a plurality of third channels 64 are formed in the ceiling plate 62. The third channels 64 are formed at appropriate intervals, for example. The third channel 64 is preferably provided at a position facing the first channel 44 when the board 26 is not installed on the floor plate portion 42 . For this reason, it is preferable that the third channel 64 be provided at a position facing the opening edge 58 as the second channel when the board 26 is placed directly above the first channel 44 . Although it is preferable that the third channel 64 be placed directly above the position where the board 26 is assumed to be placed, some deviation is allowed due to the tubular member 70 described later.

The third channel 64 is formed in an appropriate shape, such as a rectangular shape or a circular shape. The third channel 64 allows the upper side and lower side of the ceiling plate 62 to communicate with each other. The third channel 64 not only communicates the upper side and the lower side of the ceiling plate 62, but also is used as a passage for wiring and piping.

As shown in FIGS. 1 and 3, at least one of the opening edge (second channel) 58 and the third channel 64 is located on the opposite side of the inside of the ceiling-side chamber 24 and the channel base (bottom) 52 of the panel 26. It has a tubular member (ventilation unit) 70 that communicates with the inside of the upper part (near the top plate 54a). The tubular member 70 shown in FIG. 3 is formed, for example, in a bellows shape, and one end is fixed to the top plate 54a so as to cover the opening edge (second channel) 58 of the board 26, and the other end 70a is fixed to the top plate 54a so as to cover the opening edge (second channel) 58 of the board 26. It is fixed to the ceiling board 62 so as to cover it. In this embodiment, the other end 70a of the tubular member 70 is formed, for example, as a substantially square annular frame. The shape of the other end 70a of the tubular member 70 is preferably the same as the opening shape of the third channel 64. The tubular member 70 may be made of any appropriate material or shape, such as cloth, metal, or rubber, as long as it allows communication between the inside of the board 26 and the inside of the ceiling chamber 24. be able to. In this way, when the tubular member 70 has appropriate flexibility, a margin can be provided for the connection between the opening edge (second channel) 58 and the third channel 64.

As shown in FIG. 1, an air conditioner 28 is connected to the floor chamber 22 and the ceiling chamber 24. The air conditioner 28 is installed at a location where maintenance work such as daily inspection can be easily performed. The air conditioner 28 shown in FIG. 1 may be placed outdoors or indoors.

An intake section (air supply section) 28a of an air conditioner 28 is connected to the floor chamber 22. The air intake section 28a is connected to the floor chamber 22, and introduces air having a temperature lower than the temperature inside the plurality of panels 26 into the floor chamber 22. The temperature of the air taken in from the intake portion 28a is changed as appropriate by controlling the air conditioner 28, for example.

An exhaust section (air exhaust section) 28b of an air conditioner 28 is connected to the ceiling side chamber 24. The exhaust section 28b is connected to the ceiling-side chamber 24 and exhausts the air passed through the plurality of panels 26 to the ceiling-side chamber 24. As an example, the air conditioner 28 exhausts a portion of the air from the exhaust section 28b to the outside, such as to the outside of the structure 10, for example. The air conditioner 28 heat-exchanges the remaining air from the exhaust section 28b and the air from outside, such as the outside of the structure 10, and supplies cold air with a temperature lower than that inside the panel 26 from the intake section 28a to the floor chamber 22. supply

In this embodiment, the intake section 28a and the exhaust section 28b are each part of the air conditioner 28, and part of the air circulates therein. Furthermore, the air conditioner 28 introduces a portion of the air into the structure 10 from outside the structure 10 as needed. Note that the intake section 28a and the exhaust section 28b may have independent structures. The air intake section 28a may simply take in air from outside the structure 10, control the temperature to an appropriate temperature, and introduce it into the floor chamber 22. Further, the exhaust section 28b may simply have the function of sucking air and exhausting it to the outside of the structure 10 or the like.

As shown in FIG. 4, the floorboard 42a is provided with a mounting portion 48 on which a first ventilation shutter 46 for opening and closing the first channel 44 is mounted. In this embodiment, the mounting portion 48 is formed into a rectangular annular shape similar to the shape of the first channel 44, for example. The mounting portion 48 is fixed to the lower side of the opening edge of the first channel 44 of the floor plate 42a.

When the board 26 is not placed directly above the plurality of first channels 44, the first ventilation shutter 46 shown in FIG. 5 is placed on the placement part 48 of the first channel 44. The first ventilation shutter 46 has a substantially square plate shape, for example. The first ventilation shutter 46 is formed with a weight that does not move due to the pressure of the air sucked into the floor chamber 22 from the intake portion 28a. When the first ventilation shutter 46 is placed on the placement part 48, the inside and outside of the floor chamber 22 are closed. The first ventilation shutter 46 has a handle 46a. The operator can attach and detach the first ventilation shutter 46 above the mounting portion 48, that is, above the floorboard 42a, by grasping the handle 46a. For this reason, the first ventilation shutter 46 does not move due to the pressure of the air sucked into the floor chamber 22 from the air intake portion 28a, but is formed to have a weight that allows the operator to grasp and move it.

Note that when the first ventilation shutter 46 is removed from the first channel 44, the first ventilation shutter 46 is stored in an appropriate position. The storage position of the first ventilation shutter 46 may be inside or outside the space 18 of the structure 10.

As shown in FIG. 6, a second ventilation shutter 66 that opens and closes the third channel 64 is mounted on the ceiling plate 62. When the board 26 is not arranged directly below among the plurality of third channels 64, a second ventilation shutter 66 shown in FIG. 7 is arranged in the third channel 64. The second ventilation shutter 66 has a cover plate 66a and a fitting part 66b. The fitting portion 66b is formed into a rectangular plate shape that closes the opening edge of the third channel 64. The cover plate 66a covers the opening edge of the third channel 64, and is larger than the fitting part 66b, for example, formed in a rectangular plate shape. Therefore, the cover plate 66a is caught on the ceiling plate 62 and prevents the second ventilation shutter 66 from falling downward. The fitting portion 66b cooperates with the lid plate 66a to close the third channel 64, thereby preventing air from the ceiling-side chamber 24 from being exhausted into the space 18.

The operator presses the fitting part 66b of the second ventilation shutter 66 from below toward the frame ceiling 14 of the ceiling-side chamber 24, and presses it above the third channel 64, that is, above the ceiling plate 62. The second ventilation shutter 66 is removable. When the second ventilation shutter 66 is placed in the third channel 64, the inside and outside of the ceiling side chamber 24 at the position where the second ventilation shutter 66 is placed in the third channel 64 are is occluded. Note that when the second ventilation shutter 66 is removed from the third channel 64, the second ventilation shutter 66 is placed, for example, on the ceiling plate 62.

When installing the panel 26 on the floor plate portion 42, the floor plates 42a and 42b are moved as necessary. Then, the first ventilation shutter 46 is removed from the floorboard 42a on which the board 26 is installed so as to open the first channel 44 of the floorboard 42a on which the board 26 is installed. Further, the second ventilation shutter 66 is removed from the ceiling plate 62 so as to open the third channel 64 directly above the floor plate 42a on which the panel 26 is installed. Then, the board 26 is installed on the floor plate 42a with the first channel 44 open, and the opening edge 58 of the top plate 54a of the board 26 and the third channel 64 are connected by a tubular member 70.

Among the plurality of first channels 44 , the first channel 44 directly below the panel 26 communicates with the floor chamber 22 , and the first channel 44 located outside directly below the panel 26 is closed by a first ventilation shutter 46 . has been done. Therefore, in this embodiment, there is no place in the space between the floor plate 42b and the ceiling plate 62 on the outside of the panel 26 that directly communicates with the floor chamber 22. Among the plurality of third channels 64 , the third channel 64 directly above the panel 26 communicates with the ceiling side chamber 24 , and the third channel 64 located away from directly above the panel 26 is connected to the second ventilation shutter 66 . It's blocked.

The operation of cooling the interior of the panel 26 using the panel cooling system 20 of the structure 10 configured as described above and the maintenance work of the panel cooling system 20 will be described.

The air conditioner 28 supplies air at an appropriate pressure to the floor chamber 22 from an intake section 28a using, for example, a fan. The air conditioner 28 heat-exchanges and cools the air taken into the exhaust section 28b through the ceiling side chamber 24 by, for example, rotation of a fan, and supplies the cooled air to the intake section 28a. In this way, the air conditioner 28 takes in warm air (for example, air with a temperature similar to or higher than the temperature around various devices on the panel 26 ) through the ceiling side chamber 24 , exchanges heat with it, and supplies cold air ( For example, air whose temperature is about the same as or lower than the temperature around the various devices on the panel 26 is taken in. Note that the exhaust section 28b of the air conditioner 28 can take in not only warm air but also air entering the ceiling side chamber 24 into the air conditioner 28.

The air taken into the floor chamber 22 passes through the floor chamber 22, the first channel 44, the channel base 52 of the board 26, and the box body 54, and then passes through the opening edge (second channel) 58 provided at the top of the box body 54. , tubular member 70 , and exits through the third channel 64 and into the ceiling chamber 24 . That is, the air conditioner 28 allows air to pass through the first channel 44 of the floor chamber 22 directly below each panel 26 to the ceiling side chamber 24 through the box body 54 of each panel 26 to the plurality of panels 26. .

The temperature within the box 54 of each board 26 is typically higher than the temperature of the air supplied into the box 54 of each board 26 through the first channel 44 . Therefore, air with a temperature lower than the temperature inside the box 54 of each panel 26 flows from the air intake section 28a of the air conditioner 28 through the floor chamber 22, the first channel 44, and the channel base 52 of the panel 26 into the box 54. When supplied, the various devices inside the box 54 of each panel 26 and their surroundings are cooled, and temperature increases in the various devices are suppressed. The air flowing inside the box 54 from the bottom to the top flows through the opening edge (second channel) 58 of the panel 26 and the tubular member 70, and then flows from the third channel 64 to the ceiling side chamber 24.

The air flowing into the ceiling side chamber 24 is collected by the air conditioner 28 through the exhaust part 28b.

The various devices in the plurality of panels 26 are cooled simultaneously by, for example, one air conditioner 28.

In this way, the panel cooling system 20 uses, for example, one air conditioner 28 to simultaneously introduce air at a temperature lower than the temperature around various devices in the panels 26 to the plurality of panels 26. Various equipment within 26 can be cooled. Therefore, even if each panel 26 is not provided with a fan and an air conditioner (for example, an air conditioner), the panel cooling system 20 uses an air conditioner 28 separate from each panel 26 to operate various devices in a plurality of panels 26. Can be cooled.

The method of cooling by the board cooling system 20 in the board 26 is to supply air at a lower temperature compared to the temperature inside the board 26 through the plurality of first channels 44 of the floor chamber 22 and into the board 26 directly above the first channels 44. and directing the air that has passed through the inside of the board 26 to the outside of the board 26 from an opening edge (second channel) 58 provided at the top of the board 26. In this embodiment, the air that has passed through the panel 26 is led out into the ceiling-side chamber 24 outside the panel 26. According to the cooling method using the panel cooling system 20 according to the present embodiment, a plurality of first channels 44 are arranged in the floor plate section 42 on which the panel 26 is installed, and the first channels 44 are directly introduced into the panel 26. Various devices inside the plurality of panels 26 can be cooled by the cold air. Therefore, the cooling required for the plurality of panels 26 can be performed by, for example, one air conditioner 28. By introducing cold air into the panel 26 from directly below the panel 26, various devices within the panel 26 can be cooled more efficiently than by cooling the inside of the panel 26 through the outside of the panel 26.

Maintenance work for the panel cooling system 20 will be explained. By using the panel cooling system 20 according to this embodiment, there is no need to provide air conditioning equipment (cooling device) for each panel 26. The air conditioner 28 is not connected directly to each panel 26, but indirectly. In the panel cooling system 20 according to this embodiment, a direct connection point between the air conditioner 28 and the panel 26 can be eliminated. By using the panel cooling system 20 according to this embodiment, the air conditioner 28 can be installed at a position away from the panel 26. Therefore, in the panel cooling system 20 according to the present embodiment, the manufacturing and maintainability of the air conditioner 28 can be improved compared to the case where the air conditioner 28 is installed for each panel 26. When using the panel cooling system 20 according to the present embodiment, for example, by performing maintenance on one air conditioner 28, the operator is performing air conditioning maintenance on a plurality of panels 26. Further, since it is not necessary to attach the air conditioner 28 to each panel 26, the number of parts required for maintenance etc. can be reduced.

Note that the number of the plurality of first channels 44 is greater than the number of panels 26, and air at a lower temperature than the temperature inside the panel 26 is supplied to the floor plate 42b and the ceiling into the panel 26 directly above the first channels 44. When introducing directly from the floor chamber 22 without passing through the space between the plate 62 and the plate 62, the lower temperature is selectively introduced through the first channel 44 of the plurality of first channels 44, which the plate 26 is installed directly above. The first ventilation shutter 46 prevents low temperature air from entering the first channel 44 where the panel 26 is not installed directly above. Therefore, air whose temperature is lower than the temperature inside the panel 26 can be efficiently introduced into the panel 26, and various devices inside the panel 26 can be efficiently cooled.

Furthermore, by using the panel cooling system 20 according to the present embodiment, it is possible to reduce the time required for the worker to attach the air conditioner 28 to each panel 26 (manufacturing operation).

Therefore, by using the panel cooling system 20 according to this embodiment, the number of parts of the panel cooling system 20 can be reduced, and the work time for manufacturing and maintaining the panel 26 can be reduced. Therefore, according to the present embodiment, it is possible to provide the panel cooling system 20 and the structure 10 that can reduce the maintenance work time required for each panel 26.

In the board cooling system 20 according to this embodiment, the boards 26 are preferably arranged not only in the horizontal direction in FIG. 1 but also in the depth direction (not shown).
The air conditioner 28 is not limited to the one shown in FIG. 1, and for example, the air conditioner 28 may be installed in the depth direction (not shown). For example, when the panel cooling system 20 has a plurality of air conditioners 28, the inside of the floor chamber 22 may be partitioned to limit the number of panels 26 to be cooled by one air conditioner 28, or the inside of the floor chamber 22 may be opened and a plurality of air conditioners 28 may be used. The range that the cooling air can reach with the air conditioner 28 may be widened. In this case as well, it is preferable that the number of panels 26 be greater than the number of air conditioners 28. Note that the number of intake sections 28a and the number of exhaust sections 28b may be different.

In the present embodiment, an example has been described in which the intake section 28a is connected to the floor chamber 22 and the exhaust section 28b is connected to the ceiling side chamber 24 in one air conditioner 28. Various types of air conditioners can be used as the air conditioner 28. For example, if the temperature outside the structure 10 is lower than the temperature inside the panel 26, a blower or the like that does not perform heat exchange may be used instead of the air conditioner 28.

For example, the air conditioner 28 takes in air from, for example, the outside of the structure 10, exchanges heat with the air conditioner 28, and takes in cold air into the floor chamber 22 through an intake portion 28a connected to the floor chamber 22. The air conditioner 28 may exhaust the air exhausted into the ceiling-side chamber 24 by the air conditioner 28 to, for example, the outside of the structure 10 from the exhaust portion 28b. In this case as well, one air conditioner 28 can cool a plurality of panels 26 while ventilating the space 18 inside the structure 10.

In this embodiment, an example in which one panel 26 is installed directly above one first channel 44 has been described. It is also suitable that one board 26 is installed so as to cover a plurality of first channels 44, for example two.

The first ventilation shutter 46 is preferably configured to be attached and detached above the floorboard 42a, and also to be configured to open and close the first channel 44 by sliding. At this time, if the first ventilation shutter 46 is movable along the back surface of the floorboard 42a, it is possible to prevent the first ventilation shutter 46 from getting in the way when the board 26 is placed.

The second ventilation shutter 66 is preferably configured to be attached or removed above the ceiling plate 62, or to be configured to open and close the third channel 64 by sliding. At this time, if the second ventilation shutter 66 is movable along the back surface of the ceiling board 62 (the surface on the frame ceiling 14 side), the second ventilation shutter 66 will get in the way when the panel 26 is placed. It is prevented from becoming.

As described above, the panel cooling system 20 according to the present embodiment can simultaneously cool a greater number of panels 26 than the number of air conditioners 28. Since air is passed from directly below the panel 26 to above the panel 26, bending of the air can be reduced, and various devices inside the panel 26 can be efficiently cooled. In the panel cooling system 20 according to this embodiment, the air conditioner 28 does not need to be disposed in each panel 26. Therefore, the maintenance work time required for each panel 26 can be reduced. Therefore, according to the present embodiment, it is possible to provide the panel cooling system 20 and the structure 10 that can reduce the maintenance work time required for each panel 26.

(Second embodiment)
A structure 10 having a panel cooling system 20 according to a second embodiment will be described using FIGS. 8 and 9. FIG. The structure 10 according to the present embodiment is a modification of the structure 10 according to the first embodiment, and the same reference numerals are used for the same members or members having the same functions as those explained in the first embodiment. , and detailed explanation will be omitted. This also applies to the third embodiment and the modified examples of the third embodiment described below.

As shown in FIG. 8, at least one of the plurality of first channels 44 has air passing through the channel base 52 of the panel 26 as it moves away from the intake section 28a of the air conditioner 28. Guide portions 72a, 72b, and 72c are provided to facilitate passage. The guide portions 72a, 72b, and 72c adjust the flow rate of air passing through each first channel 44 per unit time.

Three first channels 44 are shown in FIG. The first guide portion 72a is disposed in the short distance first channel 44 closest to the intake portion 28a. The second guide portion 72b is arranged in the first channel 44 furthest from the intake portion 28a. The third guide 72c is arranged in the first channel 44 at an intermediate distance between the near and far distances.

As shown in FIGS. 8 and 9, each guide portion 72a, 72b, 72c has a guide plate 74 fixed to the outer edge of the first channel 44. As shown in FIGS.

The guide plate 74 can be constructed by inserting the guide plate 74 toward the first channel 44 from the cable entry port of the channel base 52, for example, after placing the panel 26 on the floor plate 42a, and then inserting the guide plate 74 toward the first channel 44, for example, by placing the upper part of the guide plate 74 on the panel 26, etc. Attach to. Thereby, the guide plate 74 is fixed to the channel base 52 of the panel 26. The guide plate 74 is fixed, for example, to the inner edge of the first channel 44 on the farthest side from the intake portion 28a. Therefore, the guide plate 74 of each guide part 72a, 72b, 72c can bend the flow of air supplied from the intake part 28a and guide it to the first channel 44 to which the guide plate 74 is attached.

In addition, in FIGS. 8 and 9, an example in which each guide portion 72a, 72b, 72c is formed into a flat plate shape as a guide plate 74 will be described. Each of the guide portions 72a, 72b, and 72c may be formed as a curved surface, such as a half-pipe shape with the inside facing toward the intake portion 28a.

Here, as shown in FIG. 8, when comparing the first guide part 72a and the second guide part 72b, among the guide plates 74 of the second guide part 72b, the direction from the floor plate 42a to the frame floor 12 is The protruding length (protruding area) of the guide plate 74 of the first guide portion 72a is larger than the protruding length (protruding area) of the guide plate 74 of the first guide portion 72a that protrudes from the floor plate 42a toward the frame floor 12.

Then, the amount of air introduced into the floor chamber 22 from the intake portion 28a and passing through each first channel 44 is made to be the same amount per unit volume in the first guide portion 72a and the second guide portion 72b. It is preferable that a guide plate 74 is formed at. That is, the guide portions 72a, 72b, and 72c move the three first channels 44 so that the flow rate and temperature per unit time of air passing through the three first channels 44 shown in FIG. 8 are approximately constant. It is preferable that the Therefore, the guide portions 72a, 72b, and 72c can each adjust the flow rate of air passing through the first channel 44 per unit time.

The example shown in FIG. 8 shows a state in which three boards 26 are arranged side by side in the horizontal direction shown in FIG. In this case, guide portions 72a, 72b, and 72c are attached to the first channel 44. The guide portion 72a of the panel 26 close to the intake portion 28a of the air conditioner 28 reduces the amount of protrusion of the guide plate 74 toward the frame floor 12, and the guide portion 72b of the panel 26 far from the intake portion 28a of the air conditioner 28 reduces the amount of protrusion of the guide plate 74 toward the frame floor 12. increases the amount of protrusion toward the frame floor 12. Normally, the closer the first channel 44 is to the air intake section 28a of the air conditioner 28, the easier the air from the air intake section 28a can pass through. In this embodiment, the amount of downward protrusion of the guide plate 74 is made shorter as it is closer to the intake section 28a of the air conditioner 28 and longer as it is farther away, so that the first channel 44 can be passed from inside the floor chamber 22 per unit time. It is possible to easily equalize the amount (volume) of air. Therefore, whether the panel 26 is close to the air intake section 28a of the air conditioner 28 or the panel 26 is far away, the cooling performance within the panel 26 can be easily made uniform.

Note that the amount of downward protrusion of the guide plate 74 of the guide portions 72a, 72b, and 72c depends on the volume per unit time of air taken in from the intake portion 28a, the size of the floor chamber 22, and the shape and size of the first channel 44. It can vary depending on the size.

In this embodiment, as shown in FIG. 8, an example has been described in which the guide portion 72a is provided in the first channel 44 closest to the intake portion 28a. The guide portion 72a may not be provided in the first channel 44 closest to the intake portion 28a.

According to this embodiment, the guide portions 72a, 72b, and 72c are simply attached to the panel cooling system 20 described in the first embodiment.
