Outside air around the second cooling device 40 is introduced into the outside air introduction port 44a, and high temperature outside air heated by exhaust heat when passing through the outside air blowing passage 45, that is, inside air cooling, is discharged to the outside from the outside air discharge port 44b. The

  Inside the housing 41, a heat exchanger 51 is provided as means for cooling the inside air. The heat exchanger 51 is, for example, a counterflow system, and is a device that exchanges heat between the inside and outside air without mutual circulation of the inside and outside air. Further, inside the casing 41, an inside air blower 52 that generates an inside air flow in the inside air blowing path 43 and an outside air blower 53 that generates an outside air flow in the outside air blowing path 45 are provided.

  In the inside air blowing path 43, the inside air blower 52 is arranged in the vicinity of the inside air introduction port 42a, and then the heat exchanger 51 is arranged. That is, when the blower operation is performed by driving the blower 52 for inside air, the inside air in the cabinet 10 introduced from the inside air introduction port 42a passes through the heat exchanger 51 and is discharged into the cabinet 10 from the inside air discharge port 42b. .

  In the outside air blowing path 45, the outside air blower 53 is arranged in the vicinity of the outside air introduction port 44a, and then the heat exchanger 51 is arranged. That is, when the outside air blower 53 is driven to perform a blowing operation, the outside air around the second cooling device 40 introduced from the outside air introduction port 44a passes through the heat exchanger 51 and is second cooled from the outside air discharge port 44b.

  The housing 41 of the second cooling device 40 configured as described above is mounted including mounting portions T1 and T2 in a manner of closing the substantially rectangular opening 10d formed on the second mounting surface 10b side of the cabinet 10. Attached by member.

  The attachment portions T1 and T2 have the same configuration as the attachment portions T1 and T2 of the first cooling device 20. That is, the attachment portion T1 for attaching the housing 41 to the cabinet 10 above the housing 41 has an opening angle of an L-shaped part as an obtuse angle (for example, an obtuse angle in the range of 90 degrees to 93 degrees). Configured to be. Below the housing 41, the attachment portion T2 for attaching the housing 41 to the cabinet 10 has an acute angle (for example, an acute angle in the range of less than 90 degrees and 87 degrees or more) at an L-shaped portion. Composed. As a result, the outer surface 44 opposite to the mounting surface 42 of the housing 41 is tilted downward in the vertical direction and attached to the cabinet 10 to be cooled. The inclination angle between the longitudinal direction of the outer side surface 44 and the vertical direction is preferably an angle that flows toward the outer side surface 24 (in the direction away from the cabinet 10) even if raindrops enter the housing 21.

  Next, operations (actions) of the first cooling device 20 and the second cooling device 40 will be described.

  In the first cooling device 20 and the second cooling device 40, the inside air fans 32 and 52 and the outside air fans 33 and 53 are blown. Due to the blowing operation of the inside air blowers 32 and 52, the inside air flows through the inside air blowing paths 23 and 43 and passes through the inside air flow paths of the heat exchangers 31 and 51. Also, the outside air flows through the outside air blowing passages 25 and 45 by the blowing operation of the outside air blowers 33 and 53, and passes through the outside air passages of the heat exchangers 31 and 51. As a result, the heat exchangers 31 and 51 absorb the internal air, exhaust heat from the external air, and the cooled internal air is supplied into the cabinet 10.

  At this time, in the first cooling device 20, warm inside air is introduced from the inside air inlet port 22a on the lower side in the vertical direction, and the cooled inside air is discharged from the inside air outlet port 22b on the upper side in the vertical direction. On the other hand, in the second cooling device 40, warm inside air is introduced from the inside air inlet port 42a on the upper side in the vertical direction, and cooled inside air is discharged from the inside air outlet port 42b on the lower side in the vertical direction. That is, the first cooling device 20 and the second cooling device 40 are different in the discharge position of the cooled inside air, so that a circulating air flow is easily generated in the cabinet 10.

  Next, the effect of this embodiment will be described.

  (1) The casings 21 and 41 of the cooling devices 20 and 40 of the present embodiment have the outside air outlets 24a and 44a for introducing outside air and the outside air discharge for discharging the air heat-exchanged by the heat exchangers 31 and 51. The outlets 24b and 44b are provided so as to be aligned in the longitudinal direction of the casings 21 and 41 on the outer surfaces 24 and 44 side of the casings 21 and 41. The casings 21 and 41 are attached to the cabinet 10 to be cooled by tilting the outer side surfaces 24 and 44 provided with the outside air introduction ports 24a and 44a and the outside air discharge ports 24b and 44b downward in the vertical direction. As described above, since the outside air inlets 24a and 44a and the outside air outlets 24b and 44b that can serve as raindrop infiltration paths in the casings 21 and 41 are directed toward the lower side in the vertical direction, there is rainfall from the upper side in the vertical direction. Even raindrops are difficult to penetrate. Thereby, the infiltration of raindrops into the cabinet 10 to be cooled can be suppressed.

  (2) The casings 21 and 41 are attached to the cabinet 10 with the outer surfaces 24 and 44 provided with the outside air inlets 24a and 44a and the outside air outlets 24b and 44b tilted downward in the vertical direction by the attachment portions T1 and T2. It is done. That is, the casings 21 and 41 can be tilted downward in the vertical direction by adjusting the opening angle of the attachment portions T1 and T2 having a substantially L-shaped cross section.

  (3) As for the housing | casing 21 of the 1st cooling device 20, the external air introduction port 24a is located in the vertical direction upper side, and the external air discharge port 24b is located in the vertical direction lower side. As described above, when the outside air introduction port 24a is not tilted to the casing 21 located on the upper side (above) in the vertical direction than the outside air discharge port 24b, there is a high possibility that raindrops may enter from the outside air introduction port 24a. This can reduce the possibility. Furthermore, even if raindrops enter the housing 21, the housing 21 is tilted, so that the intrusion into the cabinet 10 can be suppressed.

  (4) The casing is a casing 21 as a first casing provided on the first mounting surface 10 a side of the box-shaped cabinet 10, and the second mounting surface 10 b side facing the first mounting surface 10 a of the cabinet 10. And a casing 41 as a second casing. The casing 21 and the casing 41 are attached to the cabinet 10 with the outer surfaces 24 and 44 provided with the outside air inlets 24a and 44a and the outside air outlets 24b and 44b being inclined downward in the vertical direction. With such a configuration, the casings 21 and 41 can be provided in symmetrical positions with the cabinet 10 as the center, and can be arranged in a balanced manner.

  (5) The outside air introduction port 24 a is located above the opening 35 a of the cover 35 in the vertical direction, and the outside air introduction port 44 a is located above the opening 55 a of the cover 55 in the vertical direction. That is, since the openings 35a and 55a of the covers 35 and 55 located outside the outside air introduction ports 24a and 44a are located below the respective outside air introduction ports 24a and 44a in the vertical direction, raindrops from the openings 35a and 55a. Even if it is intruded, it is possible to suppress intrusion into the outside air inlets 24a, 44a above it.

  In addition, you may change the said embodiment as follows.

  In the above embodiment, the first cooling device 20 and the second cooling device 40 (housings 21 and 41) are provided on both surfaces (the first mounting surface 10a and the second mounting surface 10b) of the cabinet 10 to be cooled. However, you may employ | adopt the structure which provides the 1st cooling device 20 and the 2nd cooling device 40 only in one side. Moreover, you may employ | adopt the structure which provides only the 1st cooling device 20, and the structure which provides the 2nd cooling device 40. FIG.
