Description

[Technical Field]

[0001] The present invention relates to an electronics unit. [Background technology]

[0002] In recent years, the amount of information processed by electronic devices has increased, and the amount of heat generated by the electronic components mounted on electronic devices has also tended to increase. Therefore, there is a demand for a structure that can efficiently discharge the heat generated by the electronic components inside the electronic device during operation to the outside of the electronic device to cool the electronic device.

[0003] Electronic devices are equipped with large-scale integrated circuits and other electronic components that generate a lot of heat (hereinafter referred to as "high-heat components"). For this reason, cooling is required to keep the inside of the electronic device below a certain temperature. Methods for cooling the inside of electronic devices can be broadly divided into liquid cooling and air cooling. The more common method is air cooling. Air cooling methods are classified into natural cooling, which does not use a fan, and forced cooling, which uses a fan.

[0004] Control panels used in industrial applications have a structure in which electronic devices equipped with high-heat-generating components are housed inside a housing. These types of control panels are often installed in unmanned buildings where daily maintenance by humans is difficult, and in such cases, cooling by natural air is required so that there is no need to worry about fan failure.

[0005] Patent document 1 discloses a technology in which the inside of a housing that houses multiple electronic devices is separated into an intake area and an exhaust area by a diagonal partition, and cool air is drawn into the intake area and hot air is exhausted from the exhaust area. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-212401 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the technique described in Patent Document 1 has the following problems. The diagonal partition plate is arranged diagonally across an area (hereinafter referred to as the "storage area") in which multiple electronic devices are stored. In other words, the diagonal partition plate extends into the storage area. Therefore, when arranging multiple electronic devices in the storage area, it is necessary to ensure space between adjacent electronic devices in the vertical direction to place the diagonal partition plate, and to determine the relative positions of the electronic devices and the diagonal partition plate so that no large gaps are created between the adjacent electronic devices in the vertical direction. Therefore, the technology described in Patent Document 1 has the disadvantage of limited flexibility in layout.

[0008] An object of the present invention is to provide an electronic device unit that can efficiently cool electronic devices housed in a housing and that has a high degree of freedom in layout. [Means for solving the problem]

[0009] In order to solve the above problems, for example, the configurations described in the claims are adopted. The present application includes multiple means for solving the above-mentioned problems, and one example is an electronic device unit including multiple electronic devices and a housing that stores the multiple electronic devices in a vertically stacked state. The electronic devices have an equipment air inlet and an equipment air outlet. The housing has a housing air inlet and a housing air outlet. A partition member is provided inside the housing to separate a first space including an intake space that communicates with the housing air inlet and a storage space that stores the multiple electronic devices, from a second space including a rear space located on the rear side of the multiple electronic devices and an exhaust space that communicates with the housing air outlet. The partition member is arranged outside the storage space and has an air vent positioned opposite the equipment air outlets of the multiple electronic devices. The first space and the second space are connected via the air vent. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide an electronic device unit that can efficiently cool an electronic device housed in a housing and that has a high degree of freedom in layout. [Brief explanation of the drawings]

[Figure 10] FIG. 10 is a perspective view of an electronic device unit according to a second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this specification and the drawings, elements having substantially the same functions or configurations are designated by the same reference numerals, and redundant description will be omitted.

[0013] First Embodiment FIG. 1 is a perspective view of an electronic device unit according to the first embodiment. In this embodiment, in order to clarify the shapes and positional relationships of each part of the electronic device unit, the front direction of the electronic device unit is defined as the F direction, the back direction as the B direction, the right direction as the R direction, the left direction as the L direction, the up direction as the U direction, and the down direction as the D direction.

[0014] As shown in FIG. 1, the electronic device unit 100 according to the first embodiment includes a housing 1 and a plurality of electronic devices 2 housed in the housing 1. The electronic device unit 100 is preferably applied to a control panel or the like that requires cooling of the electronic devices 2 by natural air cooling. The housing 1 is a hollow rectangular parallelepiped (hexahedron) formed into a box shape that is long in the vertical direction. The housing 1 is preferably made of metal. However, if the required strength of the housing 1 can be ensured, the housing 1 may be made of resin.

[0015] Multiple electronic devices 2 are stored inside the housing 1 in a stacked state (in layers) in the vertical direction. However, an appropriate gap is maintained between adjacent electronic devices 2 in the vertical direction. The above-mentioned definitions of directions are equally applied to both the housing 1 and the electronic devices 2. Furthermore, in this specification, in order to distinguish between the front of the housing 1 and the front of the electronic devices 2, the front of the housing 1 will be referred to as the housing front, and the front of the electronic device 2 will be referred to as the device front. This also applies to surfaces other than the front (rear, side, top, bottom).

[0016] The housing 1 has a housing front 1a, a housing back 1b, two (a pair of left and right) housing side surfaces 1c and 1d, a housing top surface 1e, and a housing bottom surface 1f, and has an internal space surrounded by these six surfaces. The six surfaces of the housing 1 are essentially formed by six plates. Therefore, the housing front surface may be referred to as a housing front plate, the housing back surface as a housing back plate, the housing side surfaces as housing side panels, the housing top surface as a housing top plate, and the housing bottom surface as a housing bottom plate. A door (not shown) is attached to the front of the housing 1 in an openable and closable manner so that the electronic device 2 can be inserted and removed from the housing 1. Rails (not shown) for attaching the electronic device 2 are provided on the housing side surfaces 1c and 1d. A plurality of support legs 5 are attached to the housing bottom surface 1f. The support legs 5 are arranged at the four corners of the housing bottom surface 1f. When the electronic device unit 100 is installed on the floor of a building, for example, the support legs 5 support the entire electronic device unit 100 while maintaining a space between the floor surface and the housing bottom surface 1f.

[0017] A housing air inlet 3 is provided on the housing bottom surface 1f, and a housing air outlet 4 is provided on the housing top surface 1e. The housing air inlet 3 is an opening for taking in air from the outside of the housing 1 to the inside. The housing air outlet 4 is an opening for discharging air from the inside of the housing 1 to the outside. Meanwhile, a partition member 9 is disposed inside the housing 1. The partition member 9 is fixed to the inside of the housing 1 by, for example, screwing, adhesive bonding, welding, etc. The partition member 9 is a member that divides the inside of the housing 1 into a first space 11 and a second space 12. The partition member 9 may be made of metal or resin.

[0018] In this embodiment, as an example, four electronic devices 2 are housed inside the housing 1, but the number of electronic devices 2 housed inside the housing 1 may be two or more.

[0019] FIG. 2 is a schematic perspective view showing the overall configuration of the electronic device. 2, the electronic device 2 has a front surface 2a, a rear surface 2b, two (a pair of left and right) side surfaces 2c and 2d, a top surface 2e, and a bottom surface 2f. A printed circuit board (not shown) is mounted inside the electronic device 2, and multiple electronic components are mounted on this printed circuit board. The multiple electronic components include high-heat-generating components such as large-scale integrated circuits, and generate heat when the electronic device 2 operates.

[0020] An equipment air inlet 6 is provided on the equipment side surface 2d, and an equipment air inlet 7 is also provided on the equipment bottom surface 2f. The equipment air inlet 6 and the equipment air inlet 7 are openings for taking in air from the outside of the electronic device 2 to the inside. The equipment air inlet 6 and the equipment air inlet 7 are arranged closer to the equipment front surface 2a in the depth direction of the electronic device 2. The depth direction of the housing 1 is a direction parallel to the front direction F and the rear direction B. On the other hand, an equipment exhaust port 8 is provided on the equipment rear surface 2b. The equipment exhaust port 8 is an opening for discharging air from the inside of the electronic device 2 to the outside.

[0021] Fig. 3 is a front view of the electronic device unit shown in Fig. 1, and Fig. 4 is a rear view of the electronic device unit shown in Fig. 1. Fig. 5 is a left side view of the electronic device unit shown in Fig. 1, and Fig. 6 is a right side view of the electronic device unit shown in Fig. 1. Fig. 7 is a top view of the electronic device unit shown in Fig. 1, and Fig. 8 is a bottom view of the electronic device unit shown in Fig. 1.

[0022] As shown in FIGS. 3 to 8, multiple electronic devices 2 are arranged inside the housing 1. A storage space 13 is formed inside the housing 1, and multiple electronic devices 2 are stored in this storage space 13. The multiple electronic devices 2 are arranged adjacent to each other in the vertical direction with a predetermined gap between them in the storage space 13. Each electronic device 2 is arranged with its device front face 2a close to the housing front face 1a, and its device back face 2b spaced apart from the housing back face 1b. This forms a rear space 14 (FIGS. 5 and 6) inside the housing 1. The rear space 14 is located on the rear side of the multiple electronic devices 2.

[0023] Furthermore, an intake space 15 and an exhaust space 16 are formed inside the housing 1. The intake space 15 is connected to the storage space 13. That is, the storage space 13 and the intake space 15 form a first space 11, which is a single continuous space partitioned by the partition member 9. The area of the storage space 13 when cross-sectionally taken on a horizontal plane is smaller than the area of the intake space 15 when cross-sectionally taken on a horizontal plane. Therefore, the horizontal opening area of the first space 11 is smaller for the storage space 13 than for the intake space 15.

[0024] On the other hand, the exhaust space 16 is connected to the rear space 14. That is, the rear space 14 and the exhaust space 16 form the second space 12, which is a single continuous space partitioned by the partition member 9. The area of the rear space 14 when cross-sectionally taken on a horizontal plane is smaller than the area of the exhaust space 16 when cross-sectionally taken on a horizontal plane. Therefore, the horizontal opening area of the second space 12 is smaller in the rear space 14 than in the exhaust space 16.

[0025] As described above, the first space 11 is a space including the intake space 15 and the storage space 13, and the second space 12 described above is a space including the rear space 14 and the exhaust space 16. The intake space 15 is formed between the lowest electronic device 2 and the housing bottom surface 1f. The exhaust space 16 is formed between the highest electronic device 2 and the housing top surface 1e. However, a partition member 9 is interposed between the highest electronic device 2 and the exhaust space 16. The housing bottom surface 1f is located at the bottom of the intake space 15, and the housing intake port 3 is provided on this housing bottom surface 1f. Therefore, the intake space 15 is a space that communicates with the housing intake port 3. Meanwhile, the housing top surface 1e is located at the top of the exhaust space 16, and the housing exhaust port 4 is provided on this housing top surface 1e. Therefore, the exhaust space 16 is a space that communicates with the housing exhaust port 4. In other words, the intake space 15 is a space that is connected to the space outside the housing 1 via the housing intake port 3, and the exhaust space 16 is a space that is connected to the space outside the housing 1 via the housing exhaust port 4.

[0026] The partition member 9 divides the interior of the housing 1 into a first space 11 and a second space 12, thereby controlling the flow of air within the housing 1, i.e., performing a rectifying function. The partition member 9 is disposed outside the storage space 13. The partition member 9 also has a first partition portion 9a, a second partition portion 9b, and a third partition portion 9c. The first partition portion 9a, the second partition portion 9b, and the third partition portion 9c are each formed in a plate shape.

[0027] The first partition 9a is arranged above the electronic device 2 arranged on the top row. The first partition 9a is arranged horizontally at the boundary between the storage space 13 and the exhaust space 16 in order to separate the storage space 13 and the exhaust space 16 in the height direction of the housing 1. The second partition 9b is arranged perpendicular (vertically) at the boundary between the storage space 13 and the rear space 14 in order to separate the storage space 13 and the rear space 14 in the depth direction of the housing 1. The third partition 9c is arranged below the electronic device 2 arranged on the bottom row. The third partition 9c is arranged horizontally at the boundary between the rear space 14 and the intake space 15 in order to separate the rear space 14 and the intake space 15 in the height direction of the housing 1.

[0028] The first partition 9a is disposed above the third partition 9c. The upper end of the second partition 9b is connected to the end of the first partition 9a in the rear direction B, and the lower end of the second partition 9b is connected to the end of the third partition 9c in the front direction F. As a result, the partition member 9 is disposed in a crank shape (approximately Z-shape in the right side view of FIG. 6) when viewed from the side of the housing 1.

[0029] As shown in Fig. 7, the first partition 9a is formed in a rectangular (or square) shape when viewed from above the housing 1. Of the four sides of the first partition 9a, the side in the front direction F is disposed in contact with the housing front surface 1a, the side in the left direction L is disposed in contact with the housing side surface 1c, and the side in the right direction R is disposed in contact with the housing side surface 1d. The first partition 9a blocks the flow of air that passes from the intake space 15 through the storage space 13 and heads directly toward the exhaust space 16. Specifically, the first partition 9a blocks the flow of air that passes through the space between the housing side surface 1c and the device side surface 2c and heads toward the exhaust space 16, and also blocks the flow of air that passes through the space between the housing side surface 1d and the device side surface 2d and heads toward the exhaust space 16.

[0030] 1, the second partition 9b is formed in a vertically long rectangle when viewed from the rear side of the housing 1. Of the four sides of the second partition 9b, the side facing upward in the U direction is connected to one end of the first partition 9a in the rear direction B, and the side facing downward in the D direction is connected to one end of the third partition 9c in the front direction F. In addition, the side facing leftward in the L direction of the second partition 9b is disposed in contact with the housing side surface 1c, and the side facing rightward in the R direction of the second partition 9b is disposed in contact with the housing side surface 1d.

[0031] The second partition 9b has a plurality of ventilation holes 10 formed therein. These ventilation holes 10 are provided at positions facing the device exhaust ports 8 of the plurality of electronic devices 2. When the electronic device unit 100 is viewed from the side as shown in FIGS. 5 and 6, the device rear surface 2b of the electronic device 2 on which the device exhaust port 8 is formed is preferably disposed in contact with the second partition 9b so that no gap is formed between the device rear surface 2b and the second partition 9b. However, this is not limiting, and a gap of about several millimeters may be formed between the device rear surface 2b and the second partition 9b.

[0032] When viewed from the rear side of the housing 1, it is preferable that at least a portion of the equipment exhaust port 8 of each electronic device 2 overlaps with the ventilation port 10. Furthermore, as shown in FIG. 4, it is preferable that the equipment exhaust port 8 is located within the opening area of the ventilation port 10. In this embodiment, as a preferred example, a ventilation port 10 is provided for each electronic device 2. Specifically, a plurality of ventilation ports 10 are provided in a one-to-one correspondence with the plurality of electronic devices 2. The ventilation ports 10 are formed with opening dimensions larger than the equipment exhaust port 8. The second partition 9b blocks the flow of air passing through the space between the housing side surface 1c and the equipment side surface 2c toward the rear space 14, and also blocks the flow of air passing through the space between the housing side surface 1d and the equipment side surface 2d toward the rear space 14. The second partition 9b also has a shielding portion 17 (FIG. 4). The shielding portion 17 blocks the flow of air passing through the gap between vertically adjacent electronic devices 2 toward the rear space 14.

[0033] As shown in Fig. 7, the third partition 9c is rectangular when viewed from above the housing 1. The third partition 9c is disposed so as to contact the housing side surfaces 1c and 1d and the housing rear surface 1b. Specifically, of the four sides of the third partition 9c, the side in the rear direction B is disposed so as to contact the housing rear surface 1b, the side in the left direction L is disposed so as to contact the housing side surface 1c, and the side in the right direction R is disposed so as to contact the housing side surface 1d. The third partition 9c blocks the flow of air from the intake space 15 toward the rear surface space 14 without passing through the storage space 13.

[0034] The partition member 9, which includes the above-described first partition portion 9a, second partition portion 9b, and third partition portion 9c, divides the interior of the housing 1 into a first space 11 and a second space 12, and communicates the first space 11 and the second space 12 via the ventilation hole 10. "Communication" refers to a state in which they are spatially connected.

[0035] Here, a reference embodiment for comparison with the first embodiment will be described. FIG. 9 is a perspective view of an electronic device unit according to a reference embodiment. 9, the electronic device unit 200 according to the reference embodiment includes a housing 1 and a plurality of electronic devices 2 housed in the housing 1, which is similar to the first embodiment. However, the electronic device unit 200 according to the reference embodiment does not include a partition member 9 (FIG. 1) inside the housing 1.

[0036] In the electronic device unit 200 according to the reference embodiment, when the air inside the housing 1 is heated by heat generated by electronic components in operation of each electronic device 2, buoyancy occurs in the heated air. As a result, the heated air inside the housing 1 rises and is discharged to the outside of the housing 1 through the housing exhaust port 4 on the housing top surface 1e. This creates a pressure difference between the top and bottom of the housing 1, and this pressure difference causes air to be drawn into the housing 1 through the housing intake port 3 on the housing bottom surface 1f. As a result, an air flow from the housing intake port 3 to the housing exhaust port 4, i.e., an ascending air current, is formed inside the housing 1. The phenomenon that causes such an air flow is generally called the chimney effect.

[0037] 2, if an equipment exhaust port (not shown) is provided on the equipment top surface 2e of the electronic device 2, the air heated inside the lower electronic device 2 may be discharged from the equipment exhaust port on the equipment top surface 2e and flow into the upper electronic device 2, which may hinder cooling of the upper electronic device 2. For this reason, the electronic device 2 does not have an equipment exhaust port on the equipment top surface 2e, but has an equipment exhaust port 8 only on the equipment back surface 2b.

[0038] As shown by arrow Fa in Figure 9, the air flow that forms the above-mentioned ascending air current flows from the housing air intake 3 on the bottom surface 1f of the housing through the space behind each electronic device 2 to the housing air exhaust 4 on the top surface 1e of the housing. As a result, most of the cool air taken into the housing 1 through the housing air intake 3 is discharged from the housing air exhaust 4 without passing through the inside of the electronic device 2. Therefore, air that has been warmed by the heat generated by the electronic components tends to accumulate inside the electronic device 2. As a result, the temperature of the electronic device 2 increases significantly.

[0039] In contrast, with the electronic device unit 100 according to the first embodiment, the air taken into the interior of the housing 1 through the housing air intake 3 is guided into the interior of the electronic device 2 by the rectifying function of the partition member 9, which includes the first partition portion 9a, the second partition portion 9b, and the third partition portion 9c, thereby making it possible to efficiently cool the electronic device 2. This will be described in detail below.

[0040] First, when each electronic device 2 housed inside the housing 1 operates, the electronic components mounted on the printed circuit board inside each electronic device 2 generate heat. As a result, heat is generated from each electronic device 2, and this heat warms the air in the storage space 13. This causes buoyancy in the air in the storage space 13. The storage space 13 and the exhaust space 16 are separated by a first partition portion 9a of the partition member 9. The storage space 13 and the rear space 14 are also connected via a vent 10 provided in a second partition portion 9b of the partition member 9. Therefore, the only place where the air heated in the storage space 13 can escape is through the vent 10. Therefore, the air heated in the storage space 13 flows into the rear space 14 through the vent 10 of the partition member 9.

[0041] Furthermore, the air that has flowed into the rear space 14 rises within the housing 1 due to the buoyancy described above, flows into the exhaust space 16, and is then discharged to the outside of the housing 1 through the housing exhaust port 4 on the housing top surface 1e. This creates a pressure difference between the top and bottom of the housing 1, and this pressure difference causes air to be drawn into the housing 1 through the housing intake port 3 on the housing bottom surface 1f. Here, the intake space 15 and the rear space 14 are separated by the third partition portion 9c of the partition member 9. Therefore, the air drawn in through the housing intake port 3 flows from the intake space 15 toward the storage space 13. As a result, an air flow from the housing air intake port 3 to the housing air exhaust port 4, that is, an ascending air current, is formed inside the housing 1.

[0042] The air flow that forms the above-mentioned ascending air current can be roughly divided into two. One is the air flow that passes from the housing air intake port 3 through the air intake space 15 to the storage space 13, and the other is the air flow that passes from the rear space 14 through the exhaust space 16 to the housing exhaust port 4. As a result, at the boundary between the storage space 13 and the rear space 14, a force acts through the ventilation port 10 of the partition member 9 to move air from the storage space 13 to the rear space 14. For this reason, air that has been warmed by heat generated by electronic components inside each electronic device 2 flows from the device exhaust port 8 of each electronic device 2 through the ventilation port 10 into the rear space 14, forming an ascending air current toward the exhaust space 16.

[0043] Meanwhile, in the storage space 13, air flows from the storage space 13 into the rear space 14, and air is taken into the electronic device 2 through the device inlets 6 and 7 of each electronic device 2. Then, as described above, the air taken into the electronic device 2 flows from the device outlet 8 through the vent 10 into the rear space 14. This allows most of the cool air taken into the inside of the housing 1 from the housing inlet 3 to pass through the inside of the electronic device 2 and escape into the rear space 14. Therefore, heat generated inside the electronic device 2 can be smoothly discharged to the outside of the electronic device 2.

[0044] Furthermore, the section from the rear space 14 to the exhaust space 16 is a long space in the vertical direction, which creates a stronger chimney effect and creates a strong upward air current. This increases the amount of air taken in by each electronic device 2 and the amount of air exhausted from each electronic device 2. This increases the amount of air flowing inside the electronic device 2, resulting in a high cooling effect.

[0045] Furthermore, the partition member 9 is arranged outside the storage space 13 without entering the storage space 13. Therefore, the partition member 9 does not get in the way when placing the electronic device 2 in the storage space 13. Therefore, multiple electronic devices 2 can be freely arranged in the storage space 13. As a result, it is possible to provide an electronic device unit 100 that can efficiently cool the electronic device 2 housed in the housing 1 and that has a high degree of freedom in layout.

[0046] Furthermore, inside the housing 1, the gap between adjacent electronic devices 2 in the vertical direction can be narrowed, allowing multiple electronic devices 2 to be densely arranged in the storage space 13. This allows the internal space of the housing 1 to be used effectively.

[0047] Furthermore, the second partition portion 9b of the partition member 9 is provided with a plurality of ventilation holes 10 corresponding to the plurality of electronic devices 2. That is, a ventilation hole 10 is provided for each electronic device 2. This makes it possible to increase the amount of air flowing into the rear space 14 from the device exhaust port 8 of each electronic device 2, compared to, for example, a case where one ventilation hole is formed vertically for the plurality of electronic devices 2. However, even when a configuration is adopted in which one ventilation hole is formed vertically for the plurality of electronic devices 2, the cooling effect for the electronic devices 2 can be improved compared to the electronic device unit 200 according to the reference embodiment.

[0048] Furthermore, in the first embodiment, a configuration is adopted in which the partition member 9 is provided with a shielding portion 17, and the shielding portion 17 blocks the flow of air passing through the gap between adjacent electronic devices 2 in the vertical direction toward the rear space 14. This makes it possible to increase the amount of air flowing inside the electronic device 2 compared to when the partition member 9 is not provided with the shielding portion 17.

[0049] In the first embodiment, the device exhaust port 8 of each electronic device 2 is disposed within the opening area of the ventilation port 10 when viewed from the rear side of the housing 1. This allows the flow of air discharged from the device exhaust port 8 of each electronic device 2 to be guided to the rear space 14 without being obstructed by the second partition portion 9b of the partition member 9.

[0050] Second Embodiment FIG. 10 is a perspective view of an electronic device unit according to the second embodiment. 10, the electronic device unit 100A according to the second embodiment differs from the first embodiment in the configuration of the partition member 9. Specifically, in the first embodiment, the third partition portion 9c of the partition member 9 is arranged horizontally, but in the second embodiment, the third partition portion 9c of the partition member 9 is arranged vertically. As a result, the partition member 9 is arranged in an inverted L shape when viewed from the side of the housing 1. This will be explained in detail below.

[0051] The third partition 9c is disposed so as to form the same plane as the second partition 9b. The third partition 9c extends downward in the direction D from the boundary with the second partition 9b toward the housing bottom surface 1f. The second partition 9b and the third partition 9c may be formed of a single plate or two plates. The third partition 9c is disposed perpendicular to the boundary between the rear space 14 and the intake space 15 to separate the rear space 14 and the intake space 15 in the depth direction of the housing 1. The left side L of the third partition 9c is disposed so as to contact the housing side surface 1c, and the right side R of the third partition 9c is disposed so as to contact the housing side surface 1d. The downward side D of the third partition 9c is disposed so as to contact the housing bottom surface 1f.

[0052] Inside the housing 1, the storage space 13 and the rear space 14 are separated by the second partition 9b, and the intake space 15 and the rear space 14 are separated by the third partition 9c. Therefore, the rear space 14 is formed vertically along the second partition 9b and the third partition 9c. Meanwhile, the housing air intake 3 is located closer to the front of the housing 1 than the third partition 9c. It is preferable that the housing bottom surface 1f only has this housing air intake 3. However, the housing bottom surface 1f may have a small air vent (not shown) closer to the rear of the housing 1 than the third partition 9c, provided that a sufficient amount of air can be taken in from the housing air intake 3 into the intake space 15.

[0053] According to the electronic device unit 100A of the second embodiment, as in the first embodiment described above, the air taken into the interior of the housing 1 through the housing air inlet 3 is guided into the interior of the electronic device 2 by the rectifying function of the partition member 9, thereby efficiently cooling the electronic device 2. Furthermore, since the partition member 9 is arranged outside the storage space 13 without entering the storage space 13, multiple electronic devices 2 can be arranged freely in the storage space 13. Therefore, it is possible to provide an electronic device unit 100A that can efficiently cool the electronic device 2 housed in the housing 1 and has a high degree of freedom in layout.

[0054] <Modifications, etc.> The present invention is not limited to the above-described embodiments and includes various modifications. For example, the above-described embodiments have been described in detail to facilitate understanding of the present invention, but the present invention is not necessarily limited to those including all of the configurations described in the above-described embodiments. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment. It is also possible to add the configuration of another embodiment to the configuration of one embodiment. It is also possible to delete part of the configuration of each embodiment, add other configurations, or replace it with other configurations.

[0055] For example, in the above-described embodiment, the device air intake 6 is provided on the device side surface 2d of the electronic device 2 and the device air intake 7 is provided on the device bottom surface 2f as shown in Fig. 2, but this is not limiting, and a configuration in which the device air intake is provided on the device front surface 2a or the device side surface 2c may also be adopted. In other words, it is sufficient that the device air intake of the electronic device 2 is provided on at least one of the device front surface 2a, device side surfaces 2c and 2d, and device bottom surface 2f.

[0056] Furthermore, when providing a ventilation hole 10 for each electronic device 2, the opening dimensions and opening positions of the equipment exhaust hole 8 and the ventilation hole 10 may be aligned when viewed from the rear side of the housing 1, or the opening dimensions of the equipment exhaust hole 8 may be made larger than the opening dimensions of the ventilation hole 10 and the ventilation hole 10 may be positioned within the opening area of the equipment exhaust hole 8.

[0057] Furthermore, the first partition portion 9a and the third partition portion 9c may be provided with small ventilation holes as long as they do not adversely affect the cooling of the electronic device 2. [Explanation of symbols]
