  A plurality of embodiments will be described below.

  FIG. 1 is an exemplary diagram of an electronic system A. The electronic system A includes two electronic devices 1 and 5 fixed to rack posts 111 to 114. The electronic device 1 is fixed to the columns 111 and 112, and the electronic device 5 is fixed to the columns 113 and 114. The columns 111 and 112 can hold a plurality of electronic devices so as to be aligned in the vertical direction. The same applies to the columns 113 and 114. The electronic devices 1 and 5 are rack mount type electronic devices. FIG. 1 shows an example in which the electronic devices 1 and 5 are fixed at the same height position. The electronic devices 1 and 5 are examples of first and second electronic devices.

  2A, 2B, and 3 are explanatory views of the electronic device 1. FIG. The electronic device 1 includes a housing 10, a printed circuit board P1, an electronic component E1, and a fan F1. The printed circuit board P1 on which the electronic component E1 is mounted is disposed in the housing 10. The electronic component E1 is, for example, a semiconductor chip. The electronic component E1 generates heat when electric power is supplied. The electronic component E1 is an example of a heat generating component that generates heat. The heat generating component may be a motor or a disk drive that is driven by power supply. The housing 10 defines a storage portion H1 that stores the printed circuit board P1 and the electronic component E1. The housing 10 is an example of a first housing.

  The housing 10 has a substantially rectangular parallelepiped shape, and includes a top surface 11 and a bottom surface facing each other, a front surface 13 and a back surface 14 facing each other, and a side surface 15 and a side surface 16 facing each other. The top surface 11 and the bottom surface have the largest area. The side surfaces 15 and 16 have the smallest area. The back surface 14 and the side surface 16 are orthogonal to each other. Fixing pieces 31 and 32 are provided at both ends of the front surface 13, respectively. The fixing pieces 31 and 32 protrude outward from the side surfaces 15 and 16, respectively. The fixing pieces 31 and 32 are portions fixed to the rack columns 111 and 112 by screws or the like, respectively.

  A plurality of air inlets 23 are formed on the front surface 13. An exhaust port 24 is formed on the back surface 14. The storage portion H <b> 1 communicates with the intake port 23 and the exhaust port 24. The storage portion H <b> 1 is an example of a storage portion that stores heat-generating components and communicates with the exhaust port 24. The back surface 14 is an example of a first surface formed in the housing 10. A fan F <b> 1 is fixed to the exhaust port 24. When the fan F <b> 1 is driven, air is introduced into the housing portion H <b> 1 of the housing 10 through the air inlet 23. The air introduced into the storage portion H1 exchanges heat with the electronic component E1, the electronic component E1 is cooled, and the air becomes high temperature. The high-temperature air is discharged to the outside of the housing 10 by the fan F1 through the exhaust port 24. The fan F1 is an axial flow type fan as an example.

  The casing 10 is formed with a duct portion D1. The duct portion D1 is formed in a corner portion defined by a back surface 14 and a side surface 16 extending in directions intersecting each other. The duct portion D <b> 1 includes an introduction port 44 formed on the back surface 14, a discharge port 46 formed on the side surface 16, and an inclined surface 45 formed obliquely with respect to the back surface 14 and the side surface 16. Therefore, the back surface 14 is provided with the introduction port 44 and the fan F1. In addition, although the discharge port 46 is made into the slit shape in FIG. 2, it is not limited to such a shape.

  As shown in FIG. 3, the duct portion D <b> 1 and the fan F <b> 1 are provided at positions symmetrical with respect to the center C in the longitudinal direction of the back surface 14. Specifically, the distance dF from the center C to the center axis of the fan F1 is equal to the distance dD from the center C to the center axis of the inlet 44. Details will be described later.

  FIG. 4 is an explanatory diagram of the air flow in the electronic system A. FIG. 4 shows a state where the top wall of the electronic devices 1 and 5 is removed. The electronic device 5 has the same structure, shape, and size as the electronic device 1. Therefore, the electronic device 5 includes a housing 50, a printed circuit board P5, an electronic component E5, and a fan F5. The housing 50 is an example of a second housing. The housing 50 includes a top surface, a bottom surface, a front surface 53, a back surface 54, and side surfaces 55 and 56. Fixing pieces 71 and 72 are formed at both ends of the front surface 53. An intake port 63 is formed in the front surface 53. An exhaust port 64 is formed on the back surface 54 and a fan F5 is fixed. A duct portion D5 is formed at a corner portion defined by the back surface 54 and the side surface 56. The duct portion D <b> 5 includes an introduction port 84 formed on the back surface 54, a discharge port 86 formed on the side surface 56, and an inclined surface 85 formed obliquely with respect to the back surface 54 and the side surface 56. The duct portion D5 and the fan F5 are provided at symmetrical positions with respect to the center of the back surface 54 in the longitudinal direction.

  As shown in FIG. 4, when the electronic devices 1 and 5 are arranged so that the back surfaces 14 and 54 face each other and the side surfaces 16 and 56 do not face each other, the fan F1 of the electronic device 1 and the duct portion of the electronic device 5 D5 faces and the fan F5 of the electronic device 5 and the duct part D1 of the electronic device 1 face each other. This is because, as described above, the duct portion D1 and the fan F1 are provided at positions symmetrical with respect to the center C in the longitudinal direction of the back surface 14, and the duct portion D5 and the fan F5 are disposed on the back surface 54. It is because it is provided in the position symmetrical with respect to the center in the longitudinal direction.

  Thereby, the air discharged from the exhaust port 24 of the housing 10 by the fan F1 of the electronic device 1 is guided by the inclined surface 85 via the introduction port 84 of the duct portion D5 of the electronic device 5 and discharged from the discharge port 86. Is done. Further, the air discharged from the exhaust port 64 of the housing 50 by the fan F5 of the electronic device 5 is guided to the inclined surface 45 through the introduction port 44 of the duct portion D1 of the electronic device 1 and is discharged from the discharge port 46. The That is, the duct portion D1 of the electronic device 1 guides the air blown from the electronic device 5 to the side surface 15 side, and the duct portion D5 of the electronic device 5 guides the air blown from the electronic device 1 to the side surface 55 side. To do. Since the side surfaces 15 and 55 are not opposed to each other, air is discharged to the outside of the housing 10 of the electronic device 1 and the housing 50 of the electronic device 5. The duct portions D1 and D5 are examples of guide portions capable of guiding the air formed and blown to the housings 10 and 50 to the side surfaces 15 and 55, respectively. The side surfaces 15 and 55 are examples of second surfaces formed on the housings 10 and 50, respectively.

  FIG. 5 is an explanatory diagram of an electronic system X different from the electronic system A of the present embodiment. In addition, about the part of the electronic system X similar to the electronic system A, the overlapping description is abbreviate | omitted by attaching | subjecting a similar code | symbol. Unlike the electronic devices 1 and 5, the electronic devices 1x and 5x are not provided with the duct portions D1 and D5. Therefore, the air discharged from the housing 10x by the fan F1x is blown to the back surface 54x of the housing 50x. Similarly, the air discharged from the housing 50x by the fan F5x is blown to the back surface 14x of the housing 10x. Thereby, high-temperature air stays between the housings 10x and 50x. Thereby, there exists a possibility that the housing | casing 10x and 50x may become high temperature. In order to avoid this, in the electronic system X, there is a certain limit in reducing the space between the back surface 14x of the housing 10x and the back surface 54x of the housing 50x.

  On the other hand, as shown in FIG. 4, in the electronic system A of the present embodiment, the air discharged from the housing 10 is placed on the side surface 55 side by the duct portion D5, and the air discharged from the housing 50 is placed on the side surface by the duct portion D1. Guided to the 15th side. That is, the duct portions D1 and D5 guide the blown air to the outside of the side surfaces of the housings 10 and 50. Accordingly, it is possible to suppress the retention of high-temperature air between the back surface 14 of the electronic device 1 and the back surface 54 of the electronic device 5. Thereby, even if it is a case where the electronic device 1 and the electronic device 5 are arranged close to each other, the electronic devices 1 and 5 are suppressed from becoming high temperature. Then, if the dimensions in the depth direction of a rack (or also called a rocker or a rack) on which the electronic device is mounted are constant (rack standards, etc.), the dimension in the depth direction of the electronic device can be increased. Then, if the same function (component) is mounted on the electronic device, a margin in thermal design can be ensured. Alternatively, it is possible to expect effects such as mounting of other functions (components) using the expanded space of the electronic device.

  Further, the duct part D1 is partitioned from the storage part H1. Specifically, the inclined surface 45 corresponds to the surface of the wall that partitions the duct part D1 and the storage part H1. For this reason, the air passing through the duct portion D1 of the electronic device 1 is prevented from flowing into the housing portion H1 of the electronic device 1. Therefore, the high temperature air discharged from the housing 50 through the housing portion H5 of the electronic device 5 mounted with the back surface facing the electronic device 1 flows into the housing portion H1 of the electronic device 1. Is prevented. Similarly, it is possible to prevent high-temperature air that has passed through the storage unit H1 and is discharged from the housing 10 from flowing into the storage unit H5 of the electronic device 5.

  Since the guide part for guiding the air blown from the electronic device mounted on the back face to the outside of the casings 10 and 50 is formed in a duct shape, for example, it is once introduced into the duct part D1. Air is prevented from flowing between the back surfaces 14,54. Moreover, since the duct part D1 is formed in the corner | angular part of the housing | casing 10, the duct part D1 can guide air outside the housing | casing 10 easily.

  In addition, the guide part which guides air is not limited to a duct shape. For example, the inclined surface 45 may be provided without being formed in a duct shape.

  Parts similar to those in the first embodiment are denoted by the same reference numerals, and description of the second embodiment is omitted. FIG. 6 is an explanatory diagram of an electronic device 1a employed in the electronic system B of the second embodiment. The fan F1a protrudes from the back surface 14. Further, the fan F1a has a substantially rectangular shape when viewed from the axial direction of the fan F1a. Similarly, the shape of the introduction port 44 is also substantially rectangular.

  FIG. 7 is an explanatory diagram of the air flow in the electronic system B of the second embodiment. The electronic device 5a has the same structure, shape, and size as the electronic device 1a. A part of the fan F1a of the electronic device 1a is inserted into the introduction port 84 of the electronic device 5a, and a part of the fan F5a of the electronic device 5a is inserted into the introduction port 44 of the electronic device 1a. Thereby, the air discharged | emitted from the housing | casing 10a can be introduce | transduced in the duct part D5, and the air discharged | emitted from the housing | casing 50a can be introduce | transduced in the duct part D1. Thereby, it is suppressed that the air discharged | emitted from the housing | casing 10a, 50a flows between the back surface 14 of the electronic device 1a, and the back surface 54 of the electronic device 5a. Therefore, it is suppressed that hot air stays between the back surface 14 of the electronic device 1a and the back surface 54 of the electronic device 5a. Thereby, even if it is a case where the electronic devices 1a and 5a are arranged close to each other, the electronic devices 1a and 5a are prevented from becoming high temperature. The size of the fan F1a only needs to be insertable into the introduction port 84.

  In the above embodiment, the case where two electronic devices having the same shape, structure, and size are arranged close to each other has been described as an example. However, the present invention is not limited to this. For example, the two electronic devices may have different housing sizes and shapes. In this case, it is only necessary that both devices can be arranged so that the exhaust port and the guide portion of one electronic device face the guide portion and the exhaust port of the other electronic component.

  Further, only one electronic device may be provided with a fan and an exhaust port, and the other electronic device may be provided with a guide portion without being provided with a fan and an exhaust port. In this case, it is only necessary that the exhaust port of one electronic device can be disposed so as to face the guide portion of the other electronic device. The condition for this is that the distance from the center of the first surface of one electronic device to the exhaust port and the distance from the center of the first surface of the other electronic device to the guide portion are the same.

  In the said Example, although the case where the longitudinal direction of the back surfaces 14 and 54 of the two electronic devices 1 and 5 was arrange | positioned in parallel with a horizontal direction was demonstrated to an example, it is not limited to this. For example, the case where the longitudinal directions of the back surfaces 14 and 54 of the two electronic devices 1 and 5 are arranged parallel to the vertical direction may be used.

  In the above embodiment, the fan is installed in the vicinity of the exhaust port, but the present invention is not limited to this. For example, the fan may be disposed in the vicinity of the intake port, or may be disposed in the vicinity of the central portion in the housing. If air is discharged from the exhaust port, the fan may be an axial flow type or a blower type. The number of fans is not limited to one.

  In the case of Example 1, the shape of the exhaust port is not limited. In the case of the second embodiment, the shape of the exhaust port may be any as long as a fan can be inserted.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.
