It becomes possible to function without.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an exploded perspective view showing an outdoor housing 10 of the present invention. The outdoor housing 10 shown in the figure includes a main body 20 having a substantially box shape and two heat exchange units mounted on the uppermost surface (hereinafter referred to as “ceiling surface”) 23 in the Z1 direction of the main body 20. The heat exchanger 30 and the heat exchanger cover 40 disposed on the upper portion of the main body 20 to cover the heat exchanger 30 are roughly configured. The outdoor housing 10 is made of, for example, a steel plate or aluminum.

  Inside the main body 20, a space 70 is provided for housing electronic devices such as the wireless unit 50 and the amplifier unit 60. A plurality of electronic components 51 are packaged and accommodated in the wireless unit 50. In addition, a fan 52 that sucks air flowing through the electronic component 51 is provided above the electronic component 51 in the wireless unit 50. The amplifier unit 60 is placed on the wireless unit 50. An amplifier 61 is built in the amplifier unit 60. In addition, a fan 62 that sucks air flowing in the amplifier 61 is provided above the amplifier 61 in the amplifier unit 60. The internal structure of the space 70 that accommodates the wireless unit 50 and the amplifier unit 60 will be described later.

  A storage box 90 for storing a sheet 103 to be described later is provided below the space 70 of the main body 20.

  A rear cover 21 having a sunshade function is fixed to an opening surface (hereinafter referred to as “rear surface”) in the X1 direction of the main body 20. Specifically, a back cover hook metal fitting (not shown) is provided on the upper part of the back surface of the main body 20, and the back cover 21 is hooked on the metal fitting. Thereby, when attaching the back cover 21 to the main-body part 20 by hand, or removing from the main-body part 20, it can prevent that the back cover 21 falls by dead weight. Further, the lower portion of the back cover 21 is screwed to the main body portion 20, but by positioning the back cover 21 on the back cover hooking metal fitting, positioning can be performed so that the screw can be easily tightened.

  A front door 22 having a sunshade function is provided on an opening surface (hereinafter referred to as “front surface”) in the X2 direction of the main body 20 via a hinge. Therefore, the front door 22 can be rotated and opened with respect to the main body 20. In addition, on the upper portion of the front door 22, three convex portions 26 described later are formed.

  In addition, the side surface of the main body 20 in the Y1 direction and the Y2 direction has a sunshade function. The ceiling surface 23 of the main body 20 has a rectangular shape. At substantially the center of the ceiling surface 23, two openings 24 for fitting the heat exchangers 30 are formed corresponding to the number of the heat exchangers 30.

  On the XY plane at the center of the two heat exchangers 30, a heat exchanger arrangement plate 31 is provided. The heat exchanger 30 is disposed on the ceiling surface 23 of the main body 20 via a heat exchanger disposed plate 31.

  Three convex portions 27 described later are formed on the outer peripheral portion of the ceiling surface 23 on the front door 22 side. Further, a frame base portion 25 is provided in the vicinity of the outer peripheral portion of the ceiling surface 23 along the outer peripheral portion. By placing the heat exchanger cover 40 on the frame base portion 25, the heat exchanger cover 40 is disposed on the ceiling surface 23 and covered with the heat exchanger 30. Further, penetrating cutout portions 28 are formed at a plurality of locations on the front door 22 side and the back cover 21 side of the frame base portion 25, which will be described later.

  Thus, in the outdoor housing 10 that accommodates the wireless unit 50 and the amplifier unit 60 and is installed outdoors, the heat exchanger 30 is provided in the upper portion of the outdoor housing 10 for the following reason.

  That is, when the heat exchanger 30 is provided on the front door 22 side of the outdoor housing 10, the heat exchanger 30 is opened when the front door 22 is opened for adjustment or maintenance of the wireless unit 50 or the amplifier unit 60 or the like. Will leave the main body. Accordingly, the outdoor housing 10 cannot be sufficiently cooled, the temperature in the space 70 rises, and the function of the wireless unit 50 or the amplifier unit 60 accommodated in the outdoor housing 10 may be deteriorated. . Moreover, if the heat exchanger 30 is placed on the back cover 21 side, the length of the outdoor housing 10 in the X1-X2 direction becomes long, which is not preferable because of limitations on the place where the outdoor housing 10 is installed. Furthermore, when the heat exchanger 30 is disposed on the front door 22 or the back cover 21 in the first place, a strong and heavy material is required in consideration of the weight of the heat exchanger 30. This is inconvenient when the front door 22 is opened or closed or when the rear cover 21 is attached or detached.

  On the other hand, when the heat exchanger 30 is provided on the ceiling surface 23 in the upper part of the outdoor housing 10 as in the present embodiment, it is based on the low-temperature air outside the outdoor housing 10 while keeping the space portion 70 sealed. Thus, the wireless unit 50 and the amplifier unit 60 can be cooled. That is, even if the front door 22 and the back cover 21 are opened, the heat exchanger 30 remains inside the outdoor housing 10, and temperature rise of the wireless unit 50 and the amplifier unit 60 can be prevented. In addition, since the outdoor housing 10 can have a sealed structure, it is possible to prevent moisture from entering the space 70. Further, it is possible to avoid an increase in the shape and weight of the front door 22 and the back cover 21, and there is no restriction on the installation location of the outdoor housing 10.

  Next, the structure of the heat exchanger 30 will be described. 2 is an external configuration diagram of the heat exchanger 30 shown in FIG. 1, (A) is a view of the heat exchanger 30 shown in FIG. 1 as viewed from X1 to X2, and (B) is a diagram. It is the figure which looked at the heat exchanger 30 shown to 1 to the direction of Y1 from Y1. FIG. 3 is a schematic configuration diagram in which the fins 32 built in the heat exchanger 30 shown in FIG. 1 are viewed from X2 to X1.

  In the heat exchanger 30, fins 32 shown in FIG. The fin 32 is made of aluminum, for example. A plurality of heat pipes 33 are provided in the fin 32. The heat pipe 33 is made of, for example, copper. Water circulates heat inside the heat pipe 33.

  Further, as described above, the heat exchanger arrangement plate 31 is provided in the center of the heat exchanger 30. The heat exchanger 30 is disposed on the ceiling surface 23 of the main body 20 via a heat exchanger disposed plate 31. Heat is dissipated, that is, radiated, by the heat exchanger 30 located above the heat exchanger plate 31, that is, the heat exchanger 30 disposed in the heat exchanger cover 40. Further, heat is received by the heat exchanger 30 below the heat exchanger arrangement plate 31, that is, the heat exchanger 30 disposed in the space 70 of the outdoor housing 10 having a sealed structure.

  In FIG. 1, two fans 34 are located on the surface of the heat exchanger 30 in the X1 direction above the heat exchanger arrangement plate 31, and two fans 35 are located below the heat exchanger arrangement plate 31. Be placed. The upper fan 34 sucks outside air, and the lower fan 35 circulates air in the space 70 of the outdoor housing 10. The wiring line of the upper fan 34 is connected to the terminal block 36 of the lower fan 35. The function of the heat exchanger 30 and the air flow in the space 70 will be described later. The heat exchanger 30 may be commercially available and is not limited to the above-described structure.

  Next, the attachment structure to the ceiling surface 23 of the heat exchanger 30 and the attachment structure to the frame base part 25 of the heat exchanger cover 40 are demonstrated. FIG. 4 is a cross-sectional view taken along the line AA when the heat exchanger 30 shown in FIG. 1 is attached to the ceiling surface 23 and the heat exchanger cover 40 is attached to the frame base portion 25. Note that illustration and description of the lower side of the space 70 are omitted.

  As shown by dotted lines in FIG. 4, openings 41 are respectively formed on the side surfaces of the heat exchanger cover 40 on the front door 22 side and the back cover 21 side. Furthermore, opening hoods 42 are respectively provided on the side surfaces of the heat exchanger cover 40 on the front door 22 side and the back cover 21 side so as to cover the opening 41. The lower surface 43 of the opening hood 42 is open. A punching metal plate or an expanded metal plate is attached to the open lower surface 43, and measures against EMI (Electric Magnetic Interference) are taken, and intrusion of pests and the like is prevented. Similarly, a punching metal plate or an expanded metal plate is attached to the inner side surface of the heat exchanger cover 40 having the opening 41 to which the opening hood 42 is connected, and EMI countermeasures are taken. .

  Therefore, since the heat exchanger cover 40 is provided on the ceiling surface 23 and the opening hood 42 is provided on the opening 41 of the heat exchanger cover 40, rainwater is added to the heat exchanger 30 attached to the ceiling surface 23. Does not adhere in large quantities. Furthermore, the outside air of the outdoor housing 10 can enter the heat exchanger cover 40 through the lower surface 43 of the opening hood 42, the inside of the opening hood 42, and the opening 41. Therefore, external air can be taken into the heat exchanger 30 without a large amount of rainwater adhering to the heat exchanger 30.

  By the way, the surface of the portion of the ceiling surface 23 where the heat exchanger cover 40 is covered is from the portion where the heat exchanger 30 is provided, that is, the portion where the heat exchanger arrangement plate 31 is located. 1 is inclined at a predetermined angle so as to be lowered in the X1 direction and the X2 direction shown in FIG.

  Further, penetrating cutout portions 28 are formed at a plurality of locations on the side surface of the frame base portion 25 on which the heat exchanger cover 40 is placed on the front door 22 side and the back cover 21 side.

  Therefore, even if a small amount of rainwater adheres to the ceiling surface 23 through the lower surface 43 of the opening hood 42, the inside of the opening hood 42, and the opening 41, the ceiling surface 23 is inclined, so X1 shown in FIG. The rainwater that has flowed down in the direction and the X2 direction and has flowed down from the inclined portion of the ceiling surface 23 through the notch 28 can be discharged to the outside of the outdoor housing 10.

  Therefore, rainwater can be discharged to the outside of the outdoor housing 10 with a simple structure. That is, it is possible to prevent rainwater from adhering to the ceiling surface 23 and accumulating and corroding the ceiling surface 23. Moreover, it is not desirable for rainwater to adhere to the heat exchanger 30 without restriction in order to maintain the performance of the heat exchanger 30. Therefore, the waterproof effect with respect to the heat exchanger 30 can be show | played by setting it as the above-mentioned structure.

  By the way, the heat exchanger cover 40 has the partition plate 44 which consists of aluminum, for example inside. FIG. 5 is a perspective view seen through the heat exchanger cover 40 shown in FIG. 6 is a BB cross-sectional view of the heat exchanger cover 40 shown in FIG.

  In the center of the heat exchanger cover 40, the partition plate 44 bisects the inside of the heat exchanger cover 40 into a front side (X2 direction side in FIG. 5) and a back side (X1 direction side in FIG. 5). Inside the heat exchanger cover 40, the heat exchanger cover 40 is provided so as to extend in a vertical direction (Z2 direction in FIG. 5) from the ceiling portion 45. In FIGS. 5 and 6, for convenience of explanation, the partition plate 44 is indicated by hatching.

  The partition plate 44 is formed with two recesses 46 that are open in the Z2 direction in FIG. The shape of the recess 46 is substantially the same as the cross-sectional shape of the YZ plane in FIG. 5 of the heat exchanger 30 disposed above the heat exchanger mounting plate 31. Therefore, since the partition plate 44 extends from the heat exchanger cover 40, the heat exchanger cover 40 is simply covered on the ceiling surface 23 where the heat exchanger 30 is fitted in the opening 24. The partition plate 44 can be easily fitted to the heat exchanger 30.

  As a result, the inner side of the heat exchanger cover 40 is separated by the partition plate 44 from the front side which is a side for sucking outside air into the heat exchanger 30 and the rear side which is a side which discharges air from the heat exchanger 30 and discharges it to the outside. And can be partitioned. Therefore, the outside air can be efficiently sucked into and discharged from the heat exchanger 30, and thus the cooling efficiency in the outdoor housing 10 can be improved.

  Here, without arranging the partition plate 44 as shown in FIG. 5 and FIG. 6, between the two heat exchangers, arrange in the direction perpendicular to the arrangement direction of the partition plate 44 shown in FIG. A structure that bisects the inside of the heat exchanger cover 40 is also conceivable. However, in such a structure, the outside air sucked into the heat exchanger cover 40 collides with the inner wall of the heat exchanger cover 40 and circulates inside the heat exchanger cover 40, which is not desirable.

  On the other hand, if the partition plate 44 is arranged as in the present embodiment shown in FIGS. 5 and 6, the above problem can be avoided, and the cooling efficiency can be improved with a simple structure.

  Next, the internal structure of the space 70 will be described.

  FIG. 7 is a longitudinal sectional view showing a schematic structure inside the space 70 and the heat exchanger cover 40. FIG. 8 is a perspective view of the main body 20 showing that the duct 71, the first inflow prevention plate 72, and the guide plate shown in FIG. 7 are disposed on the front door 22.

  In the space portion 70, a wireless unit portion 50 that houses the electronic component 51 shown in FIG. 1 and an amplifier unit portion 60 that contains the amplifier 61 shown in FIG. 1 are housed. The amplifier unit unit 60 is placed on the wireless unit unit 50. At the upper part of the wireless unit 50, a fan 52 for sucking air flowing in each electronic component is provided. In addition, a fan 62 for sucking air flowing in each electronic component is provided on the upper part of the amplifier unit 60.

  A duct 71 is installed inside the front door 22. The upper surface and the lower surface of the duct 71 are open, and air can flow in the duct 71 from the top to the bottom.

  A first inflow prevention plate 72 is provided above the duct 71 so as to protrude toward the back cover 21 side. The end portion of the first inflow prevention plate 72 protruding to the back cover 21 side contacts the uppermost end of the side surface of the amplifier unit portion 60 when the front door 22 is closed with respect to the main body portion 20.

  A guide plate 73 is provided below the duct 71 so as to protrude toward the back cover 21 side. The end of the first inflow prevention plate 72 protruding toward the back cover 21 contacts the lowermost end of the side surface of the wireless unit 50 when the front door 22 is closed with respect to the main body 20.

  A first shielding plate 74 is obliquely provided on the upper surface of the amplifier unit 60 so as to be in contact with the end portion of the lower surface of the heat exchanger 30 located below the heat exchanger arrangement plate 31.

  A second shielding plate 75 is obliquely provided on the upper surface of the wireless unit 50 so as to be in contact with the end of the lower surface of the amplifier unit 60.

  Further, an air duct 76 is disposed obliquely below the wireless unit 50.

  A second inflow prevention plate 77 is provided vertically from the lower surface of the space portion 70, and the end of the second inflow prevention plate 77 is in contact with the lower portion of the wireless unit portion 50.

  Next, air circulation in the space 70 having the internal structure as described above will be described. In addition, the arrow in FIG. 7 has shown the circulation direction of air.

  The outside air passes through the opening 41 of the heat exchanger cover 40 from the lower surface 43 of the opening hood 42 by the fan 34 of the heat exchanger 30 disposed above the heat exchanger mounting plate 31. And is sucked into the heat exchanger 30.

  As shown in FIGS. 2 and 3, in the heat exchanger 30, water is thermally circulated in the heat pipes 33 provided in the fins 32. That is, the heat generated from the wireless unit 50 and the amplifier unit 60 is circulated through the air in the direction of the arrow of the fan 35 of the heat exchanger 30 to enter the space 70 corresponding to the heat receiving portion of the heat pipe 33. The existing part receives heat. This heat is radiated at a portion in the heat exchanger cover 40 corresponding to the heat radiating part by circulation of water in the heat pipe 33.

  Therefore, the air in the space 70 sucked by the fan 35 becomes cooled air when passing through the heat exchanger 30. The cooled air circulates through the space 70 as follows.

  The cooled air passes through the duct 71 while cooling the wireless unit 50 and the amplifier unit 60, and smoothly flows to the lower part of the wireless unit 50 located below the space 70. The air that has flowed to the lower part is guided to the wireless unit 50 through the guide plate 73 and the air duct 76.

  The wireless unit section 50 has a fan 52 mounted on the upper part, and the air is pulled up from the lower part to the upper part by the fan 52. However, since the guide plate 73 is attached to the lower part of the duct 71, the fan of the wireless unit part 50 is mounted. The air can be sucked in by the duct 71 from the duct 71.

  Air including heat generated from the wireless unit 50 is discharged to the back cover 21 side through the second shielding plate 75 without flowing to the front door 22 side.

  The amplifier unit 60 mounted on the upper part of the wireless unit part 50 also has a fan 62 mounted on the upper part, and air is pulled up from the lower part to the upper part from the fan 62.

  Air including heat generated from the amplifier unit 60 is discharged to the back cover 21 side through the first shielding plate 74 without flowing to the front door 22 side.

  Further, a first inflow prevention plate 72 whose end is in contact with the uppermost end of the side surface of the amplifier unit 60 when the front door 22 is closed with respect to the main body 20 is provided in the upper part of the duct 71. The first inflow prevention plate 72 prevents cold air flowing from the heat exchanger 30 from being sucked from the front door 22 side of the radio unit section 50 and the amplifier unit section 60.

  Further, a second inflow prevention plate 77 whose end is in contact with the lower part of the wireless unit 50 is provided vertically from the lower surface of the space 70. The second inflow prevention plate 77 prevents the air including the heat discharged to the back cover 21 side of the wireless unit 50 from flowing into the front door 22 side.

  Thus, in the space 70 in which the wireless unit 50 and the amplifier unit 60 are accommodated, the duct 71, the first inflow prevention plate 72, the guide plate 73, the first shielding plate 74, the second shielding plate 75, the air duct. 76 and a second inflow prevention plate 77 are provided to guide the air cooled by the heat exchanger 30 to the lower part of the outdoor installation housing 10, and the back cover 21 side in the space 70 is connected to the wireless unit 50 and The discharge side of the air heated by the heat generated from the amplifier unit 60 is set as the discharge side of the air, the front door 22 side in the space 70 is set as the suction side of the air cooled by the heat exchanger 30, and the two are separated. It is structured to circulate.

  That is, the space portion 70 is completely separated into a portion where the cool air radiated by the heat exchanger 30 flows and a portion where the received warm air flows and is discharged. As a result, it is possible to separate and collect cool air on the front door 22 side and warm air on the rear cover 21 side of the radio unit 50 and the amplifier unit 60, thereby preventing them from being mixed. I can do it.

  If the space portion 70 is not configured to be completely separated into a portion where the cool air flows and a portion where the warm air flows and is discharged as in the present embodiment, the wireless unit portion 50 and the amplifier unit portion 60 are not heated. Therefore, the wireless unit 50 and the amplifier unit 60 cannot be efficiently cooled.

  On the other hand, in the structure of the present embodiment, air circulation in the space 70 is smooth, and the radio unit section 50 and the amplifier unit section 60 can be efficiently cooled with a simple structure.

  Next, the structure of the part where the front door 22 and the back cover 21 come into contact with the main body 20 will be described. Since the structure of the part where the front door 22 contacts the main body part 20 and the structure of the part where the back cover 21 and the main body part 20 contact are the same, the description of the latter is omitted with the former description.

  FIG. 9 is a diagram showing an appearance of the main body 20 when the front door 22 is removed in FIG. 1 and viewed from the Y1 direction to the Y2 direction. 10 is a cross-sectional view taken along the line AA in FIG. 1 regarding a portion where the upper portion of the front door 22 is in contact with the upper portion of the main body portion 20 when the front door 22 is closed with respect to the main body portion 20.

  Although the front door 22 side of the main body portion 20 is open, a flange portion 80 is provided along the entire circumference of the open portion.

  The flange portion 80 has a U-shaped cross-sectional shape when viewed from the Y1 direction to the Y2 direction in FIG.

  Moreover, as shown in FIG. 1, the part in the upper part of the main-body part 20 among the flange parts 80 is provided with the inclination part 150 to the left and right centering on the center of the upper part by the side of the front door 22 of the main-body part 20. .

  Accordingly, since the flange portion 80 has a U-shape, rainwater accumulates at the bottom of the U-shape, and the rainwater flows down to the left and right, that is, to the side of the main body portion 20 by the inclined portion 150. Therefore, rainwater does not accumulate on the front door 22 side of the main body 20, and when the front door 22 is opened with respect to the main body 20, the rainwater flows down into the main body 20 and is stored in the main body 20. It can prevent adhering to the part 50 and the amplifier unit part 60. Accordingly, the waterproof effect of the wireless unit 50 and the amplifier unit 60 accommodated in the main body 20 can be achieved with a simple structure.

  By the way, in the flange part 80, the metal plate 81 which contact | connects the U-shaped bottom face and is located inside the flange part 80 is provided along the perimeter of the U-shaped bottom face. The front end of the metal plate 81 on the front door 22 side has an acute angle.

  The cross section of the outer periphery of the front door 22 has a U shape opposite to the U shape of the flange portion 80. In FIG. 10, only the upper part of the front door 22 is shown for convenience of explanation, but the lower part of the front door 22 is the same as the upper part of the front door 22. The same applies to the upper and lower parts of the back cover 21.

  In the vicinity of the outer peripheral portion of the front door 22, a packing 90 such as an O-ring or rubber is attached over the entire periphery. Further, a packing abutment 91 for fixing the packing 90 is fixed to the packing 90. The packing abutment fitting 91 is also fixed to a shield member 92 located on the side opposite to the side where the packing 90 is located. The shield member 92 is mounted so as to be sandwiched between the shield member holding metal fitting 93 and the packing abutting metal piece 91 located on the side opposite to the side where the packing abutting metal piece 91 is located.

  With this structure, when the front door 22 is closed with respect to the main body portion 20, the front end of the metal plate 81 of the main body portion 20 on the front door 22 side comes into contact with the shield member 92 attached to the front door 22. 22 and the main-body part 20 adhere | attach completely. Therefore, a shielding effect against electromagnetic wave leakage can be achieved.

  Next, the columns 100 and 101 and the like that are slidably disposed in the main body 20 will be described.
