DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] First Embodiment (Mobile) Hereinafter, a moving object 1 and a portable server system 5 according to a first embodiment of the present disclosure will be described with reference to FIGS. In this embodiment, a case will be described in which the moving body 1 is a vehicle. As shown in Fig. 1, the moving body 1 has a body 2, wheels 3, and a portable server system 5. The wheels 3 are attached so as to support the body 2 from below. The wheels 3 roll, causing the moving body 1 to move in the horizontal direction.

[0011] (Portable Server System) The portable server system 5 is intended for use not only in normal environments suitable for the operation of electronic devices, but also in harsh environments, such as high or low temperature environments or high humidity environments that are not suitable for the operation of electronic devices. As shown in FIGS. 2 to 5, portable server system 5 has a server main body 10, a housing 20, a circulation fan 6, and a heat exchanger . Hereinafter, the vertical up-down direction will be simply referred to as the "up-down direction Dv," with the upper side marked "Dvu" and the lower side marked "Dvd." One of the directions perpendicular to the up-down direction Dv will be referred to as the "front-to-back direction Ds," with the front side marked "Dsf" and the rear side marked "Dsb." One of the directions perpendicular to the up-down direction Dv that is also perpendicular to the front-to-back direction Ds will be referred to as the "left-to-right direction Dw," with the right side marked "Dwr" and the left side marked "Dwl."

[0012] (Server body) The server body 10 here refers to devices such as a computer (not shown) and peripheral equipment that generate heat during operation. An example of the computer is a rack server. Examples of the peripheral equipment include a network switch and an uninterruptible power supply. To operate the server body 10 normally, cooling air A is supplied to the server body 10. The orientation of the server body 10 may be vertical or horizontal, and is not particularly limited. However, it is desirable to position the server body 10 so as not to obstruct the flow of the air A supplied to the server body 10.

[0013] In this embodiment, the server body 10 is disposed on the upper side Dvu inside the housing 20. The server body 10 is provided with an intake hole 11 for taking in cooling air A and an exhaust hole 12 for exhausting the internal air A. The intake hole 11 and the exhaust hole 12 face each other in the left-right direction Dw. In the illustrated example, the intake hole 11 is provided on the left side Dwl of the server body 10, and the exhaust hole 12 is provided on the right side Dwr of the server body 10. The server body 10 has a built-in fan 13. The built-in fan 13 operates when the portable server system 5 is operating, and blows air A from the intake hole 11 toward the exhaust hole 12. In the illustrated example, a plurality of built-in fans 13 are provided on the intake hole 11 side inside the server body 10, lined up in the up-down direction Dv. The number of built-in fans 13 can be changed as appropriate. For example, only one built-in fan 13 may be provided in the server body 10.

[0014] (Housing) The housing 20 houses the server main body 10. As shown in Fig. 2, the housing 20 is formed, for example, in a rectangular parallelepiped shape. The housing 20 is designed to be portable in size. The housing 20 forms a flow path 21 for air A from the exhaust hole 12 to the intake hole 11 inside the housing 20. The server main body 10 is cooled by the air A flowing through the flow path 21.

[0015] 3, the flow path 21 is formed in a rectangular ring shape when viewed from the front-rear direction Ds. Corners 25 are provided at the four corners of the flow path 21 when viewed from the front-rear direction Ds. Each corner 25 is formed so as to bend at approximately 90 degrees. Therefore, at each corner 25, the flow direction of the air A changes by approximately 90 degrees. Note that the corners 25 referred to here include not only the actual bent parts of the flow path 21, but also the areas near the bent parts.

[0016] The housing 20 has a sealed structure that seals the internal flow path 21. For example, the housing 20 has a housing body 22, a door section 23, and a partition member 24. The housing body 22 is formed in a rectangular parallelepiped shape that opens toward the front. The door section 23 is provided so as to cover the opening of the front side Dsf of the housing body 22. An operator can open the door section 23 to insert and remove the server body 10, the circulation fan 6 described later, and the heat exchanger 7 into and from the housing body 22. When the door section 23 is closed, the flow path 21 in the housing 20 is sealed. Since the housing 20 has a sealed structure, the flow path 21 forms a closed loop that circulates the air A in the sealed space.

[0017] The partition member 24 is provided in the center of the housing 20 as viewed in the front-rear direction Ds. The partition member 24 is provided to divide the space inside the housing 20 and form the above-mentioned annular flow path 21. The partition member 24 is provided to fill the space between the housing 20 and each component such as the server main body 10, the circulation fan 6, the heat exchanger 7, etc. The partition member 24 of this embodiment has a first partition member 24a extending in the left-right direction Dw, a second partition member 24b extending downward from the lower surface of the first partition member 24a and filling the space on both sides of the circulation fan 6 and the heat exchanger 7 in the front-rear direction Ds, which will be described later, and a third partition member 24c filling the space on both sides of the server main body 10 in the front-rear direction Ds. The server main body 10 is placed on the upper surface of the first partition member 24a. The third partition member 24c prevents the air A flowing inside the flow path 21 from flowing into the spaces on both sides of the server body 10 in the front-rear direction Ds, and reliably guides the air A into the server body 10.

[0018] (Circulation fan) The circulation fan 6 is provided in the flow path 21. A plurality of circulation fans 6 are arranged below the server main body 10. In the illustrated example, a total of four circulation fans 6 are provided. The circulation fans 6 are provided so that two of them are lined up in the left-right direction Dw when viewed from the front-rear direction Ds, and are also provided so that two of them are lined up in the front-rear direction Ds when viewed from the left-right direction Dw. The number of circulation fans 6 can be changed as appropriate. For example, only one circulation fan 6 may be provided in the flow path 21.

[0019] The circulation fan 6 blows air A in the flow direction of the flow path 21. Furthermore, the circulation fan 6 is positioned so as to blow air A not against the flow of air A caused by the built-in fan 13. The circulation fan 6 operates, for example, when the portable server system 5 is in operation, and blows air A from the right side Dwr to the left side Dwl. Note that the timing of operation of the circulation fan 6 is not limited to when the portable server system 5 is in operation, and can be changed as appropriate. For example, the circulation fan 6 may be operated when the portable server system 5 is not in operation.

[0020] In this embodiment, the circulation fan 6 is attached to the second partition member 24b. The circulation fan 6 is attached so as to penetrate the second partition member 24b in the flow direction of the air A. The second partition member 24b is provided at the same position in the flow direction as the circulation fan 6 so as to fill the flow path 21 other than the area occupied by the circulation fan 6. Further, each circulation fan 6 is formed so as to extend in the vertical direction Dv.

[0021] (heat exchanger) The heat exchanger 7 is provided in the flow path 21. A second partition member 24b may or may not be provided on both sides of the heat exchanger 7 in the front-rear direction Ds. A pair of heat exchangers 7 are provided below the server body 10 so as to sandwich the circulation fan 6 from both sides in the flow direction of the air A (both sides in the left-right direction Dw in the illustrated example). The heat exchanger 7 has a structure that passes the air A flowing through the flow path 21. An example of the structure of the heat exchanger 7 is a fin-and-tube structure. A constant temperature water circulation device (e.g., a chiller) not shown, which is arranged outside the housing 20, is connected to the heat exchanger 7. The heat exchanger 7 internally circulates the cooling water W sequentially supplied from the constant temperature water circulation device. The heat exchanger 7 exchanges heat between the cooling water W and the air A after passing through the server body 10, and cools the air A flowing through the flow path 21. The air A cooled by the heat exchanger 7 passes through the flow path 21 and is supplied to the server body 10 again.

[0022] In addition, the heat exchanger 7 is arranged directly below the ends of the left side Dwl and right side Dwr of the server body 10 when viewed from the front-to-back direction Ds, and is provided at a corner 25 of the flow path 21 where the flow direction of the air A changes. Further, each heat exchanger 7 is formed so as to extend in the vertical direction Dv.

[0023] (Action and effect) According to this embodiment, the following advantageous effects can be achieved.

[0024] In this embodiment, the portable server system 5 comprises a server main body 10 having an intake hole 11 for taking in air A and an exhaust hole 12 for exhausting the internal air A arranged opposite each other, a housing 20 that houses the server main body 10 and forms a flow path 21 for the air A from the exhaust hole 12 to the intake hole 11, a circulation fan 6 arranged within the flow path 21 and blowing the air A in the flow direction of the flow path 21, and a pair of heat exchangers 7 arranged within the flow path 21 and sandwiching the circulation fan 6 on both sides in the flow direction of the air A.

[0025] According to this embodiment, the portable server system 5 can rectify the flow of air A before and after the circulation fan 6, and can operate the circulation fan 6 efficiently. Therefore, air A at a constant temperature can be circulated within the flow path 21. Furthermore, the structure inside the housing 20 can be simplified and the installation space for the heat exchanger 7 can be reduced, improving installation efficiency. Therefore, miniaturization can be achieved while maintaining cooling performance.

[0026] Since the housing 20 has a sealed structure that seals the internal flow path 21, the inside of the housing 20 can be kept at a constant temperature and humidity without depending on the outside air. Also, since the circulation fan 6 can be operated efficiently as described above, the air A that has absorbed heat from the server main body 10 can be instantly supplied to the heat exchanger 7 for cooling. Therefore, the portable server system 5 can be operated in a harsh environment while maintaining the cooling performance.

[0027] Furthermore, when the temperature inside the housing 20 is low, the circulation fan 6 can be used as a heater to increase the internal temperature. Even when the portable server system 5 is not in operation, the circulation fan 6 can be operated to increase the internal temperature.

[0028] In addition, since a plurality of heat exchangers 7 are provided, even if one heat exchanger 7 suddenly stops operating, the other heat exchangers 7 can cool the air A in the flow path 21. In other words, the cooling mechanism of the portable server system 5 can have redundancy.

[0029] In this embodiment, the heat exchanger 7 is provided at a corner portion 25 of the flow path 21 where the flow direction of the air A changes.

[0030] By disposing the heat exchanger 7 at the corner 25, the air A flowing through the corner 25 can be dispersed and the occurrence of drift can be suppressed. This rectifies the flow of the air A and allows the heat exchanger 7 to operate more efficiently. This further improves the cooling performance.

[0031] In this embodiment, the circulation fan 6 is disposed so as to blow the air A not against the flow of the air A caused by the built-in fan 13.

[0032] This allows the circulation fan 6 and the built-in fan 13 to operate efficiently, thereby further improving the cooling performance.

[0033] In this embodiment, the housing 20 is designed to be portable.

[0034] This allows the portable server system 5 to be easily carried around, thereby improving the convenience of the portable server system 5.

[0035] In this embodiment, the circulation fan 6 and the heat exchanger 7 are arranged side by side in the up-down direction Dv with respect to the server main body 10.

[0036] It is possible to select a variation of arrangement in which the circulation fan 6 and the heat exchanger 7 are arranged side by side in the vertical direction Dv with respect to the server main body 10. In addition, it is possible to prevent the portable server system 5 from becoming large in the horizontal direction.

[0037] In this embodiment, the housing 20 has a partition member 24 provided to partition the space inside the housing 20 and form a flow path 21. The partition member 24 is provided to fill the space between the housing 20 and each component such as the server main body 10, the circulation fan 6, the heat exchanger 7, etc.

[0038] This makes it possible to prevent air A flowing through flow path 21 from flowing around each of the components arranged within housing 20, such as server main body 10, circulation fan 6, heat exchanger 7, and the like. For example, the partition member 24 has a third partition member 24c that fills the spaces on both sides in the front-rear direction Ds of the server body 10. This allows the third partition member 24c to prevent the air A flowing through the flow path 21 from flowing into the spaces on both sides in the front-rear direction Ds of the server body 10, and ensures that the air A is guided into the server body 10. This makes it possible to suppress a decrease in cooling efficiency.

[0039] Furthermore, packing tape or the like may be provided in the gaps between each of the components housed within the housing 20, such as the server main body 10, the circulation fan 6, the heat exchanger 7, and the partition member 24. In this way, even if small gaps are generated between the components after the portable server system 5 is assembled, it is possible to prevent the gaps from becoming flow paths and causing a decrease in cooling efficiency.

[0040] <Modification of the first embodiment> Hereinafter, a modified example of the first embodiment of the present disclosure will be described with reference to FIG. In this modification, the housing 20A further includes guide portions 26. The guide portions 26 are provided at the four corners of the housing main body 22 when viewed from the front-rear direction Ds. The inner surface of the guide portions 26 is curved in an arc shape so as to protrude toward the outside of the housing 20A. As a result, the inner surface of the housing 20A forming the corner portions 25 is curved in an arc shape when viewed from the front-rear direction Ds.

[0041] The portable server system 5A further includes a heat insulating material 8 and a guide vane 9. The heat insulating material 8 is attached to the inner surface of the housing 20A.

[0042] Further, the guide vane 9 is provided at a corner 25 in the flow passage 21. The guide vane 9 is curved in an arc shape following the curvature direction of the corner 25 when viewed from the front-rear direction Ds. In addition, the cooling water W flowing through the heat exchanger 7 is mixed with an antifreeze agent.

[0043] (Action and effect) In this modification, a heat insulating material 8 is attached to the inner surface of the housing 20A.

[0044] This can further reduce the effect of the outside air on the inside of the housing 20A, thereby further suppressing temperature changes inside the housing 20A and keeping the inside of the housing 20A at a constant temperature.

[0045] In this modification, the cooling water W is mixed with an antifreeze agent.

[0046] This allows the cooling water W to circulate inside the heat exchanger 7, allowing the portable server system 5A to operate even in a sub-freezing environment.

[0047] In this modification, the inner surface of the housing 20A that forms the corner 25 of the flow path 21 is curved. Furthermore, the portable server system 5A includes a guide vane 9 that is curved in an arc shape following the curvature direction of the corner 25.

[0048] This reduces the pressure loss of the air A at the corner 25, and improves the cooling performance.

[0049] Second Embodiment Hereinafter, a second embodiment of the present disclosure will be described with reference to Fig. 7. Configurations similar to those in the above-described embodiment will be given the same names and reference numerals, and descriptions thereof will be omitted as appropriate.

[0050] As shown in FIG. 7, the portable server system 105 further includes a vibration isolator 50 .

[0051] (Vibration isolator) The vibration isolator 50 is attached to the outer surface (the lower part in the illustrated example) of the housing 20. The vibration isolator 50 supports the housing 20 from below. The vibration isolator 50 reduces vibrations transmitted to the housing 20. The vibration isolator 50 may be attached to the side or top surface of the housing 20.

[0052] (Action and effect) According to this embodiment, the following advantageous effects can be achieved.

[0053] The portable server system 105 of this embodiment further includes a vibration isolator 50 that is attached to the outer surface of the housing 20 and reduces vibrations transmitted to the housing 20 .

[0054] This makes it possible to reduce vibrations and shocks transmitted to portable server system 105. As a result, breakdowns in portable server system 105 can be prevented.

[0055] <Third embodiment> Hereinafter, a third embodiment of the present disclosure will be described with reference to Fig. 8. Configurations similar to those in the above-described embodiments will be given the same names and reference numerals, and descriptions thereof will be omitted as appropriate.

[0056] As shown in FIG. 8, the server body 210 is disposed in the center of the housing 20 as viewed from the front-rear direction Ds. As a result, the flow path 221 through which the air A in the housing 20 flows is partitioned and formed in a rectangular ring shape around the server body 210 as viewed from the front-rear direction Ds. The corners 225 of the flow path 221 are provided at the four corners as viewed from the front-rear direction Ds, as in the first embodiment. The intake hole 211 is provided on the left side Dwl of the server body 210, in the middle in the vertical direction Dv. The exhaust hole 212 is provided on the right side Dwr of the server body 210, in the middle in the vertical direction Dv. The housing 20 accommodates the server body 210 so that the flow path 221 branches above and below the server body 210.

[0057] The circulation fans 206 are disposed above and below the server body 210. That is, the circulation fans 206 are provided in the flow path 221 of the upper Dvu of the server body 210 and the flow path 221 of the lower Dvd of the server body 210, respectively. Similarly to the circulation fan 206, the heat exchangers 207 are disposed above and below the server body 210. A pair of heat exchangers 207 is provided in the flow path 221 of the upper Dvu of the server body 210 so as to sandwich the circulation fan 206 of the upper Dvu from the left-right direction Dw, and a pair of heat exchangers 207 is provided in the flow path 221 of the lower Dvd of the server body 210 so as to sandwich the circulation fan 206 of the lower Dvd from the left-right direction Dw.

[0058] (Action and effect) According to this embodiment, the following advantageous effects can be achieved.

[0059] In this embodiment, the housing 20 accommodates the server body 210 such that the flow path 221 branches above and below the server body 210. The circulation fans 206 are disposed above and below the server body 210. The heat exchangers 207 are disposed above and below the server body 210, and are arranged side by side with the circulation fans 206 in the horizontal direction.

[0060] This can reduce bias in the air A flowing into the server body 210. Furthermore, the length of the flow path 221 that circulates the air A from the exhaust hole 212 to the intake hole 211 of the server body 210 is shorter than when the flow path 221 does not branch. This makes it possible to increase the amount of air per unit time supplied to the server body 210. This can further improve the cooling performance.

[0061] <Fourth embodiment> Hereinafter, a fourth embodiment of the present disclosure will be described with reference to Figures 9 to 11. Configurations similar to those in the above-described embodiments will be given the same names and reference numerals, and descriptions thereof will be omitted as appropriate.

[0062] As shown in FIG. 9 to FIG. 11, the housing 320 has a housing main body 322, a door portion 323, and a partition member 324. As shown in FIG. 9, the housing main body 322 is formed in a rectangular shape that is long in the left-right direction Dw when viewed from the front-rear direction Ds. The housing main body 322 opens forward as in the first embodiment. As shown in FIG. 10, the door portion 323 is provided so as to cover the opening of the front side Dsf of the housing main body 322 as in the first embodiment. As shown in FIG. 11, the partition member 324 is provided in the center of the housing 320 when viewed from the up-down direction Dv. The partition member 324 extends in the left-right direction Dw. The partition member 324 also extends in the up-down direction Dv so as to connect the upper surface and the lower surface of the inner surface of the housing 320. The partition member 324 divides the internal space of the housing 320, and as shown in FIG. 11, a rectangular annular flow path 321 is formed around the partition member 324 when viewed from the up-down direction Dv. Corners 325 of flow path 321 are formed at the four corners of flow path 321 when viewed from the up-down direction Dv. Each corner 325 has a bending angle of approximately 90 degrees.

[0063] The server body 10 is disposed toward the front of the housing 320, on the front side Dsf of the partition member 324 in the flow path 321. The dimension of the housing 320 in the up-down direction Dv is formed slightly larger than the dimension of the server body 10 in the up-down direction Dv.

[0064] The circulation fans 306 are disposed toward the rear of the housing 320, on the rear side Dsb of the partition member 324 in the flow path 321. The circulation fans 306 are arranged side by side in the horizontal direction relative to the server main body 10. In the illustrated example, a total of four circulation fans 306 are provided. The circulation fans 306 are provided so that two are lined up in the left-right direction Dw when viewed from the up-down direction Dv, and so that two are lined up in the up-down direction Dv when viewed from the left-right direction Dw. The number of circulation fans 306 can be changed as appropriate.

[0065] The heat exchanger 307 is disposed toward the rear of the housing 320, on the rear side Dsb of the partition member 324 in the flow path 321. The heat exchanger 307 is disposed side by side with the circulation fan 306 and the server main body 10 in the horizontal direction, and is also disposed side by side with the circulation fan 306 in the horizontal direction. The heat exchanger 307 is formed to extend in the vertical direction Dv. The dimension of the heat exchanger 307 in the vertical direction Dv is designed to be approximately the same as the dimension of the server main body 10 in the vertical direction Dv.

[0066] (Action and effect) According to this embodiment, the following advantageous effects can be achieved.

[0067] In this embodiment, the circulation fan 306 is arranged side by side in the horizontal direction relative to the server body 10. The heat exchanger 307 is arranged side by side with the circulation fan 306 and the server body 10 in the horizontal direction.

[0068] It is possible to select a variation in the arrangement of circulation fan 306 and heat exchanger 307 arranged side by side in the horizontal direction with respect to server body 10. This increases the variation in the overall dimensions of portable server system 305, and increases the degree of freedom in the mounting area of ​​portable server system 305. In addition, it is possible to prevent portable server system 305 from becoming large in the vertical direction Dv.

[0069] <Fifth embodiment> Hereinafter, a fifth embodiment of the present disclosure will be described with reference to Fig. 12. Configurations similar to those of the above-described embodiments will be given the same names and reference numerals, and descriptions thereof will be omitted as appropriate.

[0070] 12, the housing 420 has a partition member 424 and a guide portion 426. The partition member 424 is provided in the center of the housing 420 when viewed from the front-rear direction Ds. The partition member 424 is formed in a trapezoidal shape whose dimension in the left-right direction Dw gradually decreases toward the bottom. The partition member 424 divides the internal space of the housing 420, and a ring-shaped flow path 421 is formed around the partition member 424 when viewed from the front-rear direction Ds.

[0071] The guide parts 426 are provided at the four corners of the housing main body 22 as viewed from the front-rear direction Ds. The guide parts 426 include two upper guide parts 426a located at the top and two lower guide parts 426b located at the bottom. The inner surface of the upper guide part 426a is linearly inclined toward the bottom of the housing 420 as viewed from the front-rear direction Ds so as to be positioned outside in the left-right direction Dw. The inner surface of the lower guide part 426b is curved so as to protrude toward the outside of the housing 420 as viewed from the front-rear direction Ds. Therefore, the inner surface of the housing 420 forming the two corner parts 425 of the lower side Dvd of the flow path 421 is curved so as to protrude toward the outside of the housing 420.

[0072] The server main body 10 is disposed in the upper Dvu inside the housing 420 . A plurality of circulation fans 406 are disposed below the server main body 10. In the illustrated example, two circulation fans 406 are provided facing each other in the left-right direction Dw. The heat exchanger 407 is provided as a pair below the server main body 10 so as to sandwich the circulation fan 406 in the left-right direction Dw. Furthermore, the heat exchanger 407 is disposed at an angle with respect to the up-down direction Dv. The heat exchanger 407 is installed so as to connect the lower guide portion 426b and the partition member 424.

[0073] (Action and effect) According to this embodiment, the following advantageous effects can be achieved.

[0074] In this embodiment, the heat exchanger 407 is disposed so as to be inclined with respect to the vertical direction Dv.

[0075] Compared to a case where heat exchanger 407 is disposed vertically in the up-down direction Dv, the front area of ​​heat exchanger 407 (area intersecting the flow direction of air A) can be made larger. Therefore, the portable server system 405 can be designed to be smaller while ensuring the amount of heat exchange required for the operation of server main body 10 and maintaining the cooling performance.

[0076] <Modification of the Fifth Embodiment> Hereinafter, a modified example of the fifth embodiment of the present disclosure will be described with reference to Fig. 13. Configurations similar to those of the above-described embodiment will be given the same names and reference numerals, and descriptions thereof will be omitted as appropriate.

[0077] As shown in Fig. 13, the server body 10 is disposed in the center of the housing 420A when viewed from the front-rear direction Ds. As a result, the flow path 421A through which the air A in the housing 420A flows is formed in a ring shape around the server body 10 when viewed from the front-rear direction Ds. The server body 10 is also disposed so that the intake hole 11 is on the right side Dwr and the exhaust hole 12 is on the left side Dwl. Due to such an arrangement of the server body 10, the flow path 421A branches into the flow path 421A above and below the server body 10. Partition members 424A are provided on the upper and lower surfaces of housing 420A when viewed in the front-rear direction Ds.

[0078] Guide portion 426A is provided at four corners of housing main body 22 when viewed from the front-rear direction Ds. The inner surface of guide portion 426A is curved in an arc shape so as to protrude toward the outside of housing 420A when viewed from the front-rear direction Ds. Therefore, the inner surface of housing 420A forming corner portion 425A of flow path 421A is curved in an arc shape so as to protrude toward the outside of housing 420A.

[0079] The circulation fans 406A are disposed above and below the server body 10. That is, the circulation fans 406A are provided in the flow path 421A of the upper Dvu of the server body 10 and the flow path 421A of the lower Dvd of the server body 10, respectively.

[0080] The heat exchangers 407A are disposed above and below the server body 10, similar to the circulation fan 406A. A pair of heat exchangers 407A is provided in the flow path 421A of the upper Dvu of the server body 10 so as to sandwich the circulation fan 406A of the upper Dvu from the left-right direction Dw, and a pair of heat exchangers 407A is provided in the flow path 421A of the lower Dvd of the server body 10 so as to sandwich the circulation fan 406A of the lower Dvd from the left-right direction Dw. Furthermore, the two heat exchangers 407A located on the right side Dwr are installed so as to connect the guide portion 426A and the partition member 424A, respectively, and are disposed at an angle with respect to the vertical direction Dv.

[0081] Furthermore, guide vanes 9 are provided at two corners 425A on the left side Dwl in the flow passage 421A. The guide vanes 9 are curved in an arc shape following the curvature direction of the corners 425A.

[0082] (Action and effect) In this modification, the two heat exchangers 407A located on the right side Dwr are also disposed inclined with respect to the vertical direction Dv. Therefore, the same effects as those of the fifth embodiment described above can be achieved.

[0083] Sixth Embodiment Hereinafter, a sixth embodiment of the present disclosure will be described with reference to Fig. 14. Configurations similar to those of the above-described embodiments will be given the same names and reference numerals, and descriptions thereof will be omitted as appropriate.

[0084] 14, two circulation fans 506 are arranged at a predetermined interval between the pair of heat exchangers 7 in the flow direction of air A. For the two circulation fans 506 to be arranged at a predetermined interval, it is not enough to simply have some gap between the two circulation fans 506. The separation distance L between the two circulation fans 506 (separation distance L in the left-right direction Dw) needs to be at least 0.2 times and at most 5.0 times the diameter R of the circulation fans 506.

[0085] Portable server system 505 further includes a tubular portion 51 that connects two circulation fans 506. The diameter of tubular portion 51 is designed to be approximately the same as diameter R of circulation fan 506. Tubular portion 51 connects the outlet of circulation fan 506 on the upstream side to the outlet of circulation fan 506 on the downstream side.

[0086] (Action and effect) According to this embodiment, the following advantageous effects can be achieved.

[0087] In this embodiment, two circulation fans 506 are arranged between the pair of heat exchangers 7 in the flow direction of the air A at a predetermined interval.

[0088] The swirling flow generated at the outlet of the circulation fan 506 on the upstream side (exhaust hole 12 side) can be attenuated in the gap between the circulation fans 506, and the loss at the inlet of the circulation fan 506 on the downstream side (intake hole 11 side) can be reduced. Therefore, the circulation fan 506 on the downstream side can be operated efficiently. Therefore, the cooling performance can be further improved.

[0089] In this embodiment, portable server system 505 further includes a tube portion 51 that connects the outlet of upstream circulation fan 506 to the outlet of downstream circulation fan 506 .

[0090] This allows the air A to be efficiently sent from the upstream circulation fan 506 to the downstream circulation fan 506. This makes it possible to further improve the cooling performance.

[0091] Seventh Embodiment Hereinafter, the seventh embodiment of the present disclosure will be described with reference to Fig. 15. Configurations similar to those of the above-described embodiments will be given the same names and reference numerals, and descriptions thereof will be omitted as appropriate.

[0092] As shown in FIG. 15, the server portable system further includes a humidity sensor 52 and a dry air supply facility 30.

[0093] (humidity sensor) The humidity sensor 52 is provided in the flow path 21 (in the illustrated example, in the upper right corner 25 of the flow path 21 when viewed from the front-rear direction Ds). The humidity sensor 52 measures the humidity in the flow path 21.

[0094] (Dry air supply equipment) The dry air supply equipment 30 includes a dry air cylinder 31 and an air introduction tube 32 . Dry air is filled in the dry air cylinder 31. The air introduction tube 32 extends from the dry air cylinder 31 and is connected to the housing 620. The air introduction tube 32 introduces the dry air in the dry air cylinder 31 to the flow path 21 in the housing 620.

[0095] The housing 620 has a sealed structure that seals the internal flow path 21. The housing 620 is provided with a supply hole 27 to which the air inlet tube 32 is connected, and a discharge hole 28 that discharges the air A in the flow path 21 to the outside of the housing 620. The supply hole 27 is provided between the heat exchanger 7 of the left Dwl and the circulation fan 506 of the left Dwl. The discharge hole 28 is provided between the heat exchanger 7 of the right Dwr and the circulation fan 506 of the right Dwr.

[0096] When the humidity sensor 52 indicates a humidity level equal to or higher than a predetermined level, the dry air supply equipment 30 supplies dry air into the flow path 21. When supplying dry air, the air A with high humidity is discharged from the exhaust hole 28 to the outside of the housing 620, thereby preventing the air pressure in the flow path 21 from rising above the design pressure of the housing 620.

[0097] (Action and effect) According to this embodiment, the following advantageous effects can be achieved.

[0098] In this embodiment, the portable server system 605 includes a humidity sensor 52 that measures the humidity in the flow path 21 and a dry air supplying device 30 that supplies dry air into the flow path 21.

[0099] The humidity sensor 52 measures the humidity in the flow path 21, and when the humidity sensor 52 indicates a humidity level equal to or higher than a predetermined value, the dry air supply equipment 30 can supply dry air into the flow path 21. This makes it possible to maintain a low humidity environment inside the flow path 21. Also, the amount of dry air held can be minimized.

[0100] For example, even when the portable server system is operated in a hot and humid environment, by supplying dry air into the housing 620 in advance, the inside of the housing 620 can be kept dry, thereby preventing condensation from occurring inside the housing 620. Furthermore, since the housing 620 of this embodiment has a sealed structure that seals the internal flow path, the inside of the housing 620 can be kept dry for a long period of time.

[0101] (Other embodiments) Although the embodiments of the present disclosure have been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes and the like that do not depart from the gist of the present disclosure are also included.

[0102] For example, the number of various devices (server main body 10, 210, circulation fan 6, 206, 306, 406A, 506, heat exchanger 7, 207, 307, 407, 407A, built-in fan 13, 213, etc.) that make up portable server system 5, 5A, 105, 205, 305, 405, 405A, 505, 605 can be changed as appropriate.

[0103] In the above embodiment, the housings 20, 20A, 320, 420, 420A, and 620 are formed in a rectangular parallelepiped shape, but this is not limiting. The shape of the housings 20, 20A, 320, 420, 420A, and 620 can be changed as appropriate.

[0104] <Additional Notes> The portable server systems 5, 5A, 105, 205, 305, 405, 405A, 505, and 605 and the moving object 1 described in each embodiment can be understood, for example, as follows.

[0105] (1) A portable server system 5, 5A, 105, 205, 305, 405, 405A, 505, 605 according to a first aspect includes a server main body 10, 210 in which an intake hole 11, 211 for taking in air A and an exhaust hole 12, 212 for exhausting the internal air A are provided facing each other, and a housing 20, 20A, 320, 420 that accommodates the server main body 10, 210 and forms a flow path 21, 221, 321, 421, 421A for the air A from the exhaust hole 12, 212 to the intake hole 11, 211. 0, 420A, 620, a circulation fan 6, 206, 306, 406, 406A, 506 that is provided in the flow path 21, 221, 321, 421, 421A and blows air A in the flow direction of the flow path 21, 221, 321, 421, 421A, and a pair of heat exchangers 7, 207, 307, 407, 407A that are provided in the flow path 21, 221, 321, 421, 421A and sandwich the circulation fan 6, 206, 306, 406, 406A, 506 on both sides in the flow direction of air A.

[0106] According to this embodiment, the portable server system 5, 5A, 105, 205, 305, 405, 405A, 505, 605 rectifies the flow of air A in front of and behind the circulation fan 6, 206, 306, 406, 406A, 506, and can efficiently operate the circulation fan 6, 206, 306, 406, 406A, 506. Furthermore, the internal structure of the housing 20, 20A, 320, 420, 420A, 620 can be simplified, and the installation space for the heat exchanger 7, 207, 307, 407, 407A can be reduced, improving installation efficiency.

[0107] (2) The second aspect of the portable server system 5, 5A, 105, 205, 305, 405, 405A, 505, 605 is the first aspect of the portable server system 5, 5A, 105, 205, 305, 405, 405A, 505, 605, and the heat exchanger 7, 207, 307, 407, 407A may be provided at a corner 25, 425, 425A of the flow path 21, 221, 321, 421, 421A where the flow direction of air A changes.

[0108] By disposing the heat exchanger 7, 207, 307, 407, 407A at the corner 25, 425, 425A, the air A flowing through the corner 25, 425, 425A can be dispersed and the occurrence of drift can be suppressed. This rectifies the flow of the air A, allowing the heat exchanger 7, 207, 307, 407, 407A to operate more efficiently.

[0109] (3) A third aspect of the portable server system 5, 5A, 105, 205, 305, 405, 405A, 505, 605 is a portable server system 5, 5A, 105, 205, 305, 405, 405A, 505, 605 of the first or second aspect, wherein the server body 10, 210 has a built-in fan 13, 213 that blows air A from the intake hole 11, 211 toward the exhaust hole 12, 212, and the circulation fan 6, 206, 306, 406, 406A, 506 may be positioned to blow air A not against the flow of air A by the built-in fan 13, 213.

[0110] This allows the circulation fans 6, 206, 306, 406, 406A, 506 and the built-in fans 13, 213 to operate efficiently.

[0111] (4) A fourth aspect of the portable server system 105 may be any one of the portable server systems of the first to third aspects, and may further include a vibration isolator 50 attached to the outer surface of the housing 20 to reduce vibrations transmitted to the housing 20.

[0112] This makes it possible to reduce vibrations and shocks transmitted to the portable server system 105 .

[0113] (5) A fifth aspect of the portable server system 205, 405A is a portable server system 205, 405A of any one of the first to fourth aspects, wherein the housing 20, 420A accommodates the server body 210, 10 so that the flow paths 221, 421A branch above and below the server body 210, 10, the circulation fans 206, 406, 406A are arranged above and below the server body 210, 10, and the heat exchangers 207, 407, 407A are arranged above and below the server body 210, 10 and may be arranged horizontally in line with the circulation fans 206, 406, 406A.

[0114] This can reduce bias in the air A flowing into the server main body 210, 10. Furthermore, the length of the flow path 221, 421A that circulates the air A from the exhaust holes 212, 12 to the intake holes 211, 11 of the server main body 210, 10 is shorter than when the flow path 221, 421A does not branch. Therefore, the amount of air per unit time supplied to the server main body 210, 10 can be increased.

[0115] (6) A sixth aspect of the portable server system 305 is any one of the first to fourth aspects of the portable server system 305, wherein the circulation fan 306 is arranged horizontally in line with the server main body 10, and the heat exchanger 307 is arranged horizontally in line with the circulation fan 306 and the server main body 10.

[0116] It is possible to select a variation of arrangement in which circulation fan 306 and heat exchanger 307 are arranged side by side in the horizontal direction with respect to server body 10. In addition, it is possible to prevent portable server system 305 from becoming large in the vertical direction Dv.

[0117] (7) The portable server system 405, 405A of the seventh aspect is the portable server system 405, 405A of any one of the first to sixth aspects, in which the heat exchanger 7, 407, 407A may be arranged at an angle with respect to the vertical direction Dv.

[0118] Compared to a case where the heat exchangers 7, 407, 407A are disposed vertically in the up-down direction Dv, the front area (area intersecting the flow direction of the air A) of the heat exchangers 7, 407, 407A can be made larger.

[0119] (8) The portable server system 505, 605 of the eighth aspect is any one of the portable server systems 505, 605 of the first to seventh aspects, and the circulation fans 506 may be arranged in pairs at a predetermined interval in the flow direction of the air A between a pair of the heat exchangers 7.

[0120] The swirling flow generated at the outlet of the circulation fan 506 on the upstream side (exhaust hole 12 side) can be attenuated in the gap between the circulation fans 506, and then the loss at the inlet of the circulation fan 506 on the downstream side (intake hole 11 side) can be reduced. Therefore, the circulation fan 506 on the downstream side can be operated efficiently.

[0121] (9) A ninth aspect of the portable server system 605 may be any one of the portable server systems 605 of the first to eighth aspects, and may include a humidity sensor 52 that measures the humidity in the flow path 21, and a dry air supply device 30 that supplies dry air into the flow path 21.

[0122] The humidity sensor 52 measures the humidity in the flow path 21, and when the humidity sensor 52 indicates a humidity level equal to or higher than a predetermined value, the dry air supply equipment 30 can supply dry air into the flow path 21. This makes it possible to maintain a low humidity environment inside the flow path 21. Also, the amount of dry air held can be minimized.
