Description

  The present invention relates to a cooling device for a communication base station.

Communication base stations such as mobile phones are equipped with a cooling device that cools the inside of the station building in order to keep the temperature inside the station building constant because the communication equipment stored inside the station building operates. (For example, refer to Patent Document 1).
Japanese Patent No. 3834873

  The present applicant has developed a cooling device having a thin case as described in Japanese Patent Application No. 2006-28496 as such a cooling device. FIG. 11 shows an external view of the cooling apparatus installed in the station building.

  As shown in FIG. 11, the cooling device 1 is attached to a door 3 of a station 2 as a housing. Inside the office building 2 is housed a communication device 6 for communicating with a mobile phone 5 or the nearest exchange station via the antenna 4, and the office building 2 is opened when the door 3 is closed. It becomes a sealed state.

  Here, FIG. 12 shows a front view of the communication device 6 housed in the station 2, and FIG. 13 shows a perspective view of the inside of the station when the station 2 is viewed from above. 12 and 13 correspond to the C arrow view and the D arrow view in FIG. 11, respectively.

  As shown in FIGS. 12 and 13, the communication device 6 includes a main device, that is, a communication device 6 a as a main device, and an auxiliary device 6 b that assists the operation of the communication device 6 a such as a battery and a power conversion device. Configured. The communication device 6 a and the auxiliary device 6 b are arranged side by side inside the station building 2.

  On the other hand, in the cooling device 1 shown in FIG. 11, as shown in FIG. 13, in the left-right direction of the case 11, an inside air passage 31 through which the inside air of the station 2 flows and an outside air passage 32 of the station 2 are arranged. In addition, an inside air inlet 22a and an inside air outlet 22b are provided on the inside air flow path 31 side of the case 11 (see FIG. 11). That is, in this cooling device 1, as shown in FIG. 11, the inside air outlet 22 b is disposed only on one side of the case 11 in the left-right direction.

  And the cooling device 11 is attached to the door 3 so that when the door 3 of the office building 2 is closed, the arrangement direction of the communication device 6a and the auxiliary device 6b coincides with the horizontal direction of the case 11. .

  For this reason, as shown in FIG. 13, the inside air outlet 22b faces only the communication device 6a out of the communication device 6a and the auxiliary device 6b, and blows out from the inside air outlet 22b as shown by the arrows in FIG. The generated inside air flows toward the communication device 6a located in front of the inside air outlet 22a, and as shown in FIG. 12, the inside air is taken in from the ventilation port 6c of the communication device 6a. Then, after a part of the inside air hits the communication device 6a, it flows toward the auxiliary device 6b adjacent to the communication device 6a.

  Since the communication device 6 generates more heat in the communication device 6a than the auxiliary device 6b, when the communication device 6 is cooled, the internal air outlet 22b is connected to the communication device 6a as in the cooling device 1 shown in FIG. It is possible to keep the temperature in the station building 2 constant by disposing the cooling air directly at only the communication device 6a.

  However, as in the cooling device 1 shown in FIG. 11, when the inside air outlet 22b is arranged at a position facing only the communication device 6a, it has been found that the problem described below occurs.

  The station 2 containing the communication device 6 needs to cope with all natural environments. When the station 2 is installed in the extremely cold region, not only the inside of the station 2 is cooled, It is necessary to control the temperature of the communication device 6 within the normal operating temperature range by heating the inside.

  Therefore, by providing a heating means such as an electric heater in the inside air flow path 31 of the cooling device 1 and heating the inside air by the heating means, it is possible to control the temperature of the communication device 6 within the normal operating temperature range.

  However, in the cooling device shown in FIG. 11, since the inside air outlet 22b is only on one side, as shown in FIG. 13, the hot air blown from the inside air outlet 22b directly hits the communication device 6a. Since the warm air is not directly applied to the auxiliary device 6b at a position directly opposite to the auxiliary device 6b, it takes time until the temperature of the auxiliary device 6b rises. And if time is taken, since the power consumption of an electric heater will increase, it is unpreferable.

  In this way, in the communication base station cooling apparatus, at least during the cooling operation, the cool air may be directly blown to at least the communication device 6a. However, during the heating operation, not only the hot air is directly blown to the communication device 6a. In the cooling device 1 shown in FIG. 11, it is difficult to directly send warm air to the auxiliary device 6 b.

  The above-described problem is not only the cooling device 1 having the configuration shown in FIG. 11, but also the cooling for communication base stations in which the internal air outlets are arranged to face only the communication device 6a out of the communication device 6a and the auxiliary device 6b. If it is a device, it is a problem that occurs in the same way.

  An object of this invention is to provide the communication base station cooling device which can heat both the communication apparatus 6a which is the main body apparatus accommodated in the station building 2, and an auxiliary device efficiently in view of the said point.

  In order to achieve the above object, the present invention provides a cooling device in which an internal air outlet is disposed at a position facing only the main body device (6a) of the main body device and the auxiliary device, provided in the case, A guide member (42a, 52) for guiding a part of the inside air to the auxiliary device by changing a part of the inside air blowing direction from the outlet is provided.

  Thus, in the present invention, the guide member is configured to change a part of the inside air blowing direction from the inside air outlet to the main body device to form the inside air flow from the inside air outlet to the auxiliary device. During the heating operation of the cooling device that blows out the inside air heated by the means from the inside air outlet, both the main body device and the auxiliary device of the communication device can be heated early.

  Specifically, as the cooling device, for example, the inside air flow path (31) and the outside air flow path (32) of the case (11) are in the same direction as the arrangement direction of the main body device (6a) and the auxiliary device (6b). The present invention is particularly effective when a configuration in which the components are arranged side by side is employed and the position of the internal air outlet is on one side of the case and is a position facing the main body device.

  Here, as the heat exchange means, for example, an inside air side heat exchanger (12) that is arranged in the inside air flow path and cools the inside air by boiling and evaporating the refrigerant by heat exchange between the refrigerant and the inside air. The heat of the refrigerant is dissipated to the outside air by condensing the refrigerant by heat exchange between the refrigerant disposed in the outside air flow path (32) and vaporized by the inside air side heat exchanger (12) and the outside air. By adopting the outside air side heat exchanger (13) to be performed, it is possible to cool the inside air by indirectly exchanging heat between the inside air and the outside air.

  Moreover, as a guide member, a louver and a duct are employable, for example. When a louver is employed, for example, a hole (43) that is an area where a plurality of ventilation holes (43a) are formed and a louver part (area where a louver (42a) as a guide member is formed ( 42) can be provided in the case (11) so as to cover the internal air outlet (22b).

  At this time, for example, the louver can be formed by raising a part of the sheet metal constituting the inside air blowing cover (41). The louver (42a) preferably has a cut-and-raised angle (θ1) of 30 to 45 degrees. Moreover, it is preferable that the louver (42a) is arrange | positioned in the position from which the distance (d1) with an inside air side heat exchanger (12) will be 10 mm.

  Further, as an example of the present invention, the heating means (18) is disposed at a position on the downstream side of the inside air flow of the inside air heat exchanger (12) and facing a lower portion than the center of the inside air heat exchanger. And a partition part (51) for partitioning the flow of the internal air that has passed through the internal air side heat exchanger into a first internal air flow that is heated by the heating means and a second internal air flow that flows above the heating means. Configuration can be adopted.

  In addition, the code | symbol in the bracket | parenthesis of each means described in the claim and this column is an example which shows a corresponding relationship with the specific means as described in embodiment mentioned later.

The shape is shorter than the length in the direction. In addition, the cross section of the main body case 11 means the cross section in the up-down direction of the main body case 11, that is, the direction perpendicular to the vertical direction.

  In addition, as shown in FIG. 2, the cooling device 1 faces the door 3 of the station 2 so that the back surface 22 of the main body case 11 faces the inside of the office building 2 and the front surface 21 faces the outside of the office building 2. It can be attached. That is, the thickness direction of the main body case 11 is the mounting direction of the cooling device 1 with respect to the station 2.

  Further, as shown in FIGS. 1A and 1D, the inside of the main body case 11 is divided into two regions by the partition wall 27 in the left-right direction of the main body case 11. The partition wall 27 has a shape along the inside of the main body case 11 and is a substantially rectangular flat plate. The partition wall 27 is disposed perpendicular to the front surface 21, the back surface 22, the upper surface 25, and the lower surface 26 of the main body case 11 so as to be parallel to the vertical direction.

  Moreover, in this embodiment, the left side in FIG. 1A is the inside air side region 31 in the internal space of the main body case 11, which is an inside air flow path through which the inside air of the station building 2 circulates, and FIG. The right side in the inside is an outside air region 32, which serves as an outside air passage through which the outside air of the station building 2 flows. Note that the positions of the inside air side region 31 and the outside air side region 32 may be interchanged, and the inside air side region 31 and the outside air side region 32 are positioned in front of the communication device 6a as described later. As described above, it is determined according to the arrangement of the communication device 6a and the auxiliary device 6b.

  As shown in FIG. 1A, in the inside air region 31, the inside air side heat exchanger 12 is arranged below the main body case 11, and the inside air fan 16 is arranged above the main body case 11. Yes. On the other hand, in the outside air region 32, the outside air heat exchanger 13 is arranged above the main body case 11, and the outside air fan 17 is arranged below the main body case 11.

  Further, as shown in FIG. 1B and FIG. 2, in the back surface 22 of the main body case 11, the inside air is located at a position facing the inside air fan 16 and a position facing the inside air heat exchanger 12, respectively. Openings 22a and 22b serving as intake ports and internal air outlets are provided.

  Moreover, as shown in FIG.1 (c), in the front surface 21 of the main body case 11, the position which opposes the external air fan 17 and the position which opposes the external air side heat exchanger 13 are respectively an external air intake. Openings 21a and 21b serving as outside air outlets are provided.

  In the present embodiment, the internal air flow path 31 and the external air flow path 32 are arranged in the left-right direction of the main body case 11, and the left-right direction of the main body case 11 is communicated in the same manner as the cooling device shown in FIGS. The inside air outlet 22b is arranged at a position facing only the communication device 6a in the communication device 6a and the auxiliary device 6b, as shown in FIG. 2, in accordance with the arrangement direction of the device 6a and the auxiliary device 6b. It has become.

  The inside air side heat exchanger 12 is, for example, a fin-tube heat exchanger, which is a multi-flow path type heat exchanger, and is disposed in the inside air region 31 as shown in FIG. Yes.

  The outside air side heat exchanger 13 is, for example, a fin-tube heat exchanger, a multi-flow path type heat exchanger, like the inside air side heat exchanger 12, and as shown in FIG. Two are provided in the outside air region 32.

  Further, a gas pipe 14 and a liquid pipe 15 are connected to the inside air side heat exchanger 12 and the outside air side heat exchanger 13. The refrigerant circulates between the inside air side heat exchanger 12 and the outside air side heat exchanger 13 via the gas pipe 14 and the liquid pipe 15.

  Thus, in the cooling device 1 of the present embodiment, a sealed refrigerant circuit is formed by the inside air side heat exchanger 12, the outside air side heat exchanger 13, the gas pipe 14, and the liquid pipe 15, and such It has two independent refrigerant circuits.

  In this refrigerant circuit, in the inside air-side heat exchanger 12, heat is exchanged between the inside air that is higher in temperature than the outside air and the liquid-phase refrigerant in the tube via the fins. As a result, the amount of heat of the inside air moves to the liquid phase refrigerant, whereby the liquid phase refrigerant boils to become a gas phase refrigerant, and the inside air is cooled.

  On the other hand, in the outside air side heat exchanger 13, heat is exchanged between the outside air having a temperature lower than that of the inside air and the gas phase refrigerant in the tube via the fins. As a result, the gas-phase refrigerant is condensed to become a liquid-phase refrigerant, and the heat of the refrigerant is radiated to the outside air.

  At this time, since the outside air side heat exchanger 13 is arranged above the inside air side heat exchanger 12, the refrigerant in the refrigerant circuit is subjected to gravity by the outside air side heat exchanger 13 → the liquid pipe 15 → the inside air side heat exchange. Natural circulation in the order of the vessel 12, and natural circulation in the order of the inside air side heat exchanger 12 → the gas pipe 14 → the outside air side heat exchanger 13 due to the pressure difference between the gas phase refrigerant and the liquid phase refrigerant.

  As described above, the cooling device 1 of the present embodiment cools the inside air of the station building 2 by using the heat exchange cycle of the refrigerant in the inside air side heat exchanger 12 and the outside air side heat exchanger 13. The inside air side heat exchanger 12, the outside air side heat exchanger 13, the gas pipe 14 and the liquid pipe 15 correspond to heat exchanging means for indirectly exchanging heat without mixing the inside air and the outside air.

  Further, in the present embodiment, one axial flow fan is used as the inside air fan 16, and the inside air is located above the main body case 11 as shown in FIGS. 1 (b) and 2. 22 a, flows through the inside air region 31 from the top to the bottom, and is discharged from the inside air outlet 22 b located below the main body case 11.

  In the present embodiment, two centrifugal fans are used as the outside air fan 17, and outside air is taken in from the outside air intake port 21 a located below the main body case 11 as shown in FIG. The air flows through the outside air region 32 from the bottom to the top, and is discharged from the outside air outlet 21b located above the main body case 11.

  Further, as shown in FIGS. 1A and 1B, the inside air region 31 is upstream of the inside air flow of the two inside air heat exchangers 12, with respect to the inside air heat exchanger 12. An electric heater 18 as a heating means is disposed above the center of the inside air heat exchanger 12 in the drawing. This heater 18 heats the inside air so that when the internal temperature of the station building 2 is lower than the set temperature, the base station is operated when the base station is operated at a low outside air temperature.

  In addition, an indoor air temperature sensor 19 is disposed on the downstream side of the internal air flow of the two internal air side heat exchangers 12 and in the vicinity of the internal air outlet 22 b of the main body case 11. The inside air temperature sensor 19 detects the temperature of the inside air blown from the inside air outlet of the main body case 11.

  For example, when the detected temperature of the inside air temperature sensor 19 is input to a control unit (not shown) and the input detection temperature is equal to or lower than the lower limit threshold temperature, the heater 18 is energized by the control unit to heat the inside air. It is supposed to be.

  Further, as shown in FIG. 2, an inside air outlet cover 41 that covers the inside air outlet 22 b is fixed to the main body case 11. The inside air blowing cover 41 protects the inside air side heat exchanger 12 and distributes the blowing direction of the inside air in two directions.

  FIG. 3 shows a front view of the inside air blowing cover 41. FIG. 4 is a sectional view taken along line IV-IV in FIG. FIG. 4 also shows the positional relationship between the inside air outlet cover 41 and the inside air side heat exchanger 12.

  As shown in FIG. 3, the inside air blowing cover 41 has a louver portion 42 provided on the lower half side and a square hole punching portion 43 provided on the upper half side.

  The louver part 42 is formed, for example, by cutting and raising a metal plate constituting the inside air blowing cover 41, and as shown in FIG. 4, a plurality of plate parts 42a for guiding the wind direction and a hole part 42b. This is a region where is formed. The direction of the wind passing through the hole 42b is determined by the plate 42a. This plate part 42a is a louver.

  In the present embodiment, the bending angle θ1 of the louver 42a is set to, for example, 30 ° so that the inside air blown from the inside air outlet 22a is directed to the auxiliary device 6b. The bending angle θ1 is an angle formed by the louver 42a with respect to the surface of the cooling device 1 facing the communication device 6.

  The louver 42a has a shape protruding toward the inside air side heat exchanger 12, and the distance d1 between the tip of the louver 42a and the inside air side heat exchanger 12 is, for example, 10 mm. In this embodiment, the louver 42a is formed by raising the plate portion 42a toward the inside air heat exchanger 12, but the louver 42a is formed by raising the plate portion 42a on the opposite side. Also good. That is, the louver 42a may have a shape protruding toward the outside of the main body case 11. In this case, the distance between the inside air blowing cover 41 and the inside air side heat exchanger 12 is the above-described distance d1.

  Further, as shown in FIG. 3, the square hole punching portion 43 is a region in which a rectangular hole 43 a as a plurality of ventilation holes is formed in the metal plate constituting the inside air blowing cover 41. In the square hole punching portion 43, the inside air simply passes through the plurality of holes 43a. The shape of the hole 43a may not be a square, but may be other shapes such as a polygon or a circle.

  For example, a screw hole 44 is provided in the peripheral edge portion of the inside air blowing cover 41 and is fixed to the main body case 11 with a screw (not shown).

  FIG. 5 shows a transmission diagram when the housing 2 is viewed from above. The cooling device 1 of this embodiment is arrange | positioned with respect to the communication apparatus 6 at the space | interval of 50-100 mm, for example. In addition, the horizontal direction length in the figure of the communication device 6 is, for example, 1000 mm.

  And since the cooling device 1 of this embodiment is provided with the inside air blowing cover 41 of the above-mentioned structure, when inside air is blown out from the cooling device 1, as shown by the arrow in FIG. The inside air that has passed through the louver 42a flows toward the communication device 6a that faces the inside air-side flow path 31, and the inside air that has passed through the louver 42a flows toward the auxiliary device 6b that faces the outside-air side flow path 32. That is, in this embodiment, the inside air blowing directions from the inside air outlet 22b are two directions, the direction toward the communication device 6a and the direction toward the auxiliary device 6b.

  Next, the operation of the cooling device of this embodiment will be described.

  When the internal temperature of the station building 2 becomes a temperature at which the communication device 6 cannot operate, for example, 10 ° C., the internal air flowing through the internal air side region 31 is heated by the heater 18, and the internal air fan 16 Hot air is blown out from the inside air outlet 22b.

  At this time, in this embodiment, since the louver 42a provided in the inside air blowing cover 41 can blow the warm air not only to the communication device 6a but also to the auxiliary device 6b, the inside air blowing direction is the inside air blowing direction. Compared with the case of only one direction from the outlet 22a toward the communication device 6a, the temperature of both the communication device 6a and the auxiliary device 6b can reach the operable temperature at an early stage, and the power consumption of the heater 18 is suppressed. The interior of the station 2 can be efficiently heated.

  Note that according to the present embodiment, even during the cooling operation of the cooling device 1, the cool air can be directly blown not only to the communication device 6a but also to the auxiliary device 6b.

  Moreover, in this embodiment, although the angle (theta) 1 of the louver 42a is 30 degrees, if it is 30-45 degrees, inside air can be directly ventilated with respect to the auxiliary | assistant apparatus 6b. As in the present embodiment, when the angle θ1 of the louver 42a is 30 °, the amount of warm air to the auxiliary device 6b can be maximized.

  Moreover, in this embodiment, the space | interval d1 is provided between the front-end | tip of the louver 42a, and the internal air side heat exchanger 12, and the internal air blowing cover 41 is installed.

  Here, it is possible to place the louver 42 a in contact with the inside air heat exchanger 12, but in this case, when the cooling device 1 is transported for reasons such as installing the cooling device 1 in the station 2. The louver 42a and the inside air side heat exchanger 12 may interfere with each other due to transportation vibration, and at least one of the louver 42a and the inside air side heat exchanger 12 may be damaged. For this reason, it is preferable to provide a space between the louver 42a and the inside air side heat exchanger 12.

  On the other hand, the flow rate of the inside air flowing out from the inside air side heat exchanger 12 decreases as the distance from the inside air side heat exchanger 12 increases, so that the wind direction is hardly changed even when it hits the louver 42a. Further, in the louver part 42 and the square hole punching part 43, the square hole punching part 43 has a smaller resistance, so that the internal air flows more easily into the square hole punching part 43 than the louver part 42, and the internal air flow rate flowing through the louver part 42 Will decrease. Therefore, from the viewpoint that the inside air blowing direction is a direction toward the auxiliary device 6b, the interval d1 between the louver 42a and the inside air side heat exchanger 12 is preferably small.

  Therefore, in the present embodiment, the distance d1 between the tip of the louver 42a and the inside air heat exchanger 12 is set to 10 mm, thereby preventing interference between the louver 42a and the inside air heat exchanger 12 due to transportation vibration, and an auxiliary device. The inside air flow toward 6b can be formed satisfactorily.

(Second Embodiment)
In FIG. 6, the front view of the internal air blowing cover 41 in 2nd Embodiment of this invention is shown.

  In the inside air outlet cover 41 shown in FIG. 3 of the first embodiment, the louver portion 42 occupies about the lower half of the entire area. However, when the heat capacity of the auxiliary device 6b is small, as shown in FIG. The area occupied by the portion 42 may be about 1/4 of the entire area.

  Thus, you may change the ratio which the louver part 42 occupies with respect to the whole area | region based on the heat capacity of the auxiliary equipment 6b.

(Third embodiment)
FIG. 7 shows an internal configuration of the cooling device according to the third embodiment of the present invention when viewed in the direction of arrow A in FIG. In FIG. 7, the same components as those in FIG. 1B are denoted by the same reference numerals as those in FIG.

  As shown in FIG. 7, the position of the heater 18 in the vertical direction may be changed to a position lower than the position of the heater 18 shown in FIG. 1B of the first embodiment.

  The position of the heater 18 in the vertical direction may be matched with the position of the auxiliary device 6b in the vertical direction inside the station 2 so that the warm air hits the auxiliary device 6b.

(Fourth embodiment)
FIG. 8 shows an internal configuration of the cooling device according to the fourth embodiment of the present invention when viewed in the direction of arrow A in FIG. In FIG. 8, the same reference numerals as those in FIG. 1B are given to the same components as those in FIG.

  In the present embodiment, as shown in FIG. 8, the inside air side heat exchanger 12 is tilted with respect to the vertical direction, and the heater 18 is located on the downstream side of the inside air flow of the inside air side heat exchanger 12, and the inside air side. It arrange | positions in the position which opposes a lower part rather than the center of the heat exchanger 12. FIG.

  And the partition plate 51 as a partition part is the inside air side area | region 31 of the main body case 11 so that the flow of the inside air which passed the inside air side heat exchanger 12 may be divided | segmented into two in an up-down direction, The side heat exchanger 12 is provided so as to be in contact with the downstream surface of the inside air flow. The partition 51 is for preventing the inside air heated by the heater 18 from rising in the inside air region 31 of the main body case 11.

  In the present embodiment, the partition portion 51 causes the flow of the internal air that has passed through the internal air side heat exchanger 12 to be heated by the heater 18 and the second internal air flow that flows above the heater 18. Therefore, warm air is blown out from below the inside air outlet 22b.
