Description

  The present invention relates to a transmission device, and more particularly to a transmission device including an amplification unit and a synthesis unit, such as an air-cooled television transmission device.

  2. Description of the Related Art In recent years, a general transmission apparatus that includes a plurality of power supply units, a plurality of amplification units, and a combiner has been widely known. A general transmission device generates a high-frequency signal in each of a plurality of amplification units using each power source of a plurality of power supply units, synthesizes this high-frequency signal in a synthesis unit, and then sends the synthesized signal via an antenna. To the receiver.

  Further, in a general transmission device, an air cooling method may be employed in order to make the device smaller than a water cooling method.

  Here, a configuration of a general transmission apparatus 1000 that employs an air cooling method will be described.

  10 to 12 are diagrams for illustrating a configuration of a general transmission apparatus 1000. FIG. 10 is a diagram showing the upper surface of the transmitting apparatus 1000. FIG. 11 is a cross-sectional view of the transmitting apparatus 1000 taken along the section C1-C1 in FIG. FIG. 12 is a cross-sectional view of the transmitting apparatus 1000 taken along the section C2-C2 in FIG. In FIG. 12, for convenience, an inlet port 1110 described later is not shown.

  As shown in FIGS. 10 to 12, the transmission apparatus 1000 includes a housing 2000, a plurality of power supply units 3000, a plurality of amplification units 4000, and a combining unit 5000.

  The housing 2000 accommodates a plurality of power supply units 3000, a plurality of amplification units 4000, and a combining unit 5000. As shown in FIG. 11, the left side surface and the right side surface of the housing 2000 are formed in a mesh shape, and a plurality of through holes are formed in the left side surface and the right side surface of the housing 2000. Each of the plurality of through holes formed on the left side surface of the housing 2000 is referred to as an intake port 2150. In addition, each of the plurality of through holes formed on the right side surface of the housing 2000 is referred to as an exhaust port 2350. In addition, a fan (not shown) that blows air from the left side surface side to the right side surface side of the transmission apparatus 1000 is disposed on one or both of the intake port 2150 side and the exhaust port 2350 side.

  As shown in FIG. 10, the plurality of power supply units 3000 are arranged on the back side of the housing 2000 so that they can be easily detached from the back side of the housing 2000. In addition, each of the plurality of power supply units 3000 is provided so as to be stacked with a gap therebetween. Each of the plurality of power supply units 3000 supplies power to each of the plurality of amplification units 4000.

  As shown in FIG. 10, the plurality of amplification units 4000 are arranged on the front side of the housing 2000. Thereby, the plurality of amplifying units 4000 can be easily detached from the front side of the housing 2000. Further, each of the plurality of amplifying units 4000 is provided so as to be overlapped with each other via a gap. Each of the plurality of amplifying units 4000 amplifies a transmission signal input from the outside of the housing 2000 using each power source of the plurality of power source units 3000. Thereafter, each of the plurality of amplifying units 4000 outputs the amplified signal to the synthesizing unit 5000.

  As shown in FIGS. 10 and 12, the combining unit 5000 is generally formed in a rectangular parallelepiped shape. The combining unit 5000 is arranged such that the largest surface among the surfaces constituting the outer surface of the combining unit 5000 faces both side surfaces of the housing 2000. The combining unit 5000 combines each of the transmission signals output from each of the plurality of amplifying units 4000. After that, the combining unit 5000 outputs the combined signal toward an antenna or the like outside the housing 2000.

  Next, the operation of a general transmission apparatus 1000 will be described.

  As shown by the arrows in FIG. 11, the air outside the casing 2000 is sucked into the casing from the air inlet 2150 formed on the left side surface of the casing 2000, and the gap between each of the plurality of amplifying units 4000 and After passing through a gap between each of the plurality of power supply units 3000, the air is exhausted out of the housing 2000 through an exhaust port 2350 formed on the right side surface of the housing 2000. As a result, the plurality of amplification units 4000 and the plurality of power supply units 3000 are cooled by air.

JP 2007-243728 A

  However, in transmitting apparatus 1000, combining unit 5000 is arranged such that the largest surface among the surfaces constituting the outer surface of combining unit 5000 faces both side surfaces of casing 2000. For this reason, the air sucked from the intake port 2150 is blocked by the synthesis unit 5000 as indicated by the arrow p1 in FIG. The air blocked by the combining unit 5000 is divided into air toward the back side (direction indicated by the arrow p2 in FIG. 10) and air toward the front side (direction indicated by the arrow p3 in FIG. 10).

  Here, the air traveling in the direction indicated by the arrow p <b> 2 stays in a region where each of the plurality of power supply units 3000 is disposed, and thus is not smoothly exhausted from the exhaust port 2350. Thereby, the some power supply part 3000 cannot be cooled efficiently.

  Moreover, the air which goes to the direction which the arrow p3 shows collides with the air which goes to the direction of the arrow p4. For example, when the air traveling in the direction indicated by the arrow p3 collides with the air traveling in the direction of the arrow p4, the traveling direction of the air traveling in the direction of the arrow p4 is the front side of the housing 200 as indicated by the arrow p5. And it changes in the direction of the right side. As described above, the air flow from the intake port 2150 to the exhaust port 2350 is disturbed inside the housing 2000, and the air toward the direction of the arrow p4 is not smoothly exhausted from the exhaust port 2350. As a result, there is a problem that the inside of the housing 2000 cannot be sufficiently cooled.

  Therefore, the present invention has been made in view of such circumstances, and an object of the present invention is to provide a transmission device that can cool the inside of a housing more efficiently.

  A related technique is also described in Patent Document 1.

  The transmission device of the present invention includes a housing, a plurality of amplifying units disposed on the front surface side of the housing and provided so as to overlap each other via a gap, and a housing so as to face each of the plurality of amplifying units. A combining unit that is arranged on the back side of the body and synthesizes signals output from each of the plurality of amplifying units; an intake port that is provided on one side surface of the casing and sucks air outside the casing into the casing; An exhaust port provided on the other side facing the one side of the housing and exhausting the air outside the housing sucked in by the air inlet to the outside of the housing, and one side of the housing through the gap An air blower that exhausts air outside the housing sucked by the air intake port from the exhaust port so that the air flows from the side to the other side surface. It is arranged so that the smallest surface faces the side surface.

  According to the transmission device and the like of the present invention, the inside of the housing can be cooled more efficiently.

The intake fan 220 is driven so that air outside the housing 200 is drawn into the intake ventilation section 210 via the intake port 215. Specifically, the intake fan 220 allows air outside the housing 200 to flow from one side of the housing 200 to the other side of the housing 200 via the gap Y (between each of the plurality of amplifiers 400). In addition, the air outside the housing 200 sucked in through the air inlet 215 is exhausted from the air outlet 235.

For example, the exhaust partition plate 225 is a metal plate formed in a mesh shape.

  The exhaust ventilation unit 230 will be described. As shown in FIG. 5, the exhaust ventilation portion 230 is a space on the right side surface of the housing 200. The exhaust ventilation portion 230 is in communication with the accommodating portion 203 through the through hole of the exhaust partition plate 225. An exhaust port 235 is formed on the upper surface side of the exhaust ventilation portion 230. The exhaust ventilation unit 230 communicates with a space outside the housing 200 through the exhaust port 235.

  The exhaust port 235 and the exhaust fan 240 will be described. The exhaust port 235 is formed on the upper surface side of the housing 200 on the right side surface side. An exhaust fan 240 is disposed in the vicinity of the exhaust port 235 (a boundary portion between the exhaust ventilation portion 230 and the space outside the housing 200). The exhaust fan 240 is driven to exhaust the air in the exhaust ventilation section 230 to a space outside the housing 200 via the exhaust port 235. Specifically, the exhaust fan 240 allows the air outside the casing 200 to flow from one side of the casing 200 to the other side via the gap Y (between each of the plurality of amplification units 300). In addition, the air outside the housing 200 sucked in through the air inlet 215 is exhausted from the air outlet 235.

  Next, the plurality of power supply units 300 will be described. As shown in FIGS. 4 to 6, the plurality of power supply units 300 are arranged on one surface side (the back side in FIGS. 1 to 6) in the housing 200. Specifically, the plurality of power supply units 300 are arranged on the back side of the plurality of amplification units 400. As shown in FIG. 6, each of the plurality of power supply units 300 is provided so as to be overlapped via a gap X. Further, as shown in FIG. 4, each of the plurality of power supply units 300 is connected to each of the plurality of amplification units 400 via the first connection unit M1.

As shown in FIG. 6, each of the plurality of amplifying units 400 is provided so as to be overlapped with the gap Y therebetween. Each of the plurality of amplifying units 400 is provided so as to be attached or detached from the front side of the housing 200. Each of the plurality of amplifying units 400 is connected to the combining unit 500 via the second connection unit M2. For example, the plurality of amplifying units 400 are arranged on ribs (not shown) formed inside the housing 200. A heat sink can be attached to the surface of each of the plurality of amplifying units 400 on the gap Y side.

  For example, the amplification unit 400 converts an AC power output from the power supply unit 300 into a DC power source. The amplifying unit 400 amplifies a signal output from an exciter (not shown) using a DC power source.

  As shown in FIG. 4, the combining unit 500 is disposed on the back side of the plurality of amplification units 400 so as to face each of the plurality of amplification units 400. The combining unit 500 combines the signals output from each of the plurality of amplifying units 400. Further, in the combining unit 500, the surface having the smallest area among the surfaces constituting the outer shape of the combining unit 500 has one side surface (left side surface shown in FIGS. 4 and 5) and the other side surface (in FIGS. 4 and 5). (Right side shown). The combining unit 500 is disposed between the plurality of amplification units 400 and the plurality of power supply units 300.

  The configuration of the transmission device 100 has been described above. Note that the intake fan 220 and the exhaust fan 240 are the air blowing units of this embodiment. In the above description, the transmission device 100 is described as including both the intake fan 220 and the exhaust fan 240. However, the transmission device 100 includes only one of the intake fan 220 and the exhaust fan 240. You may have.

  Next, the transmission operation of the transmission device 100 will be described.

  First, each of the plurality of power supply units 300 outputs an AC power supply to each of the plurality of amplification units 400. Each of the plurality of amplifying units 400 converts the AC power output from each of the plurality of power supply units 300 into a DC power source. Each of the plurality of amplifying units 400 amplifies a signal output from an exciter (not shown) of another casing using a DC power source. Each of the plurality of amplification units 400 outputs the amplified signal to the synthesis unit 500. The synthesizer 500 synthesizes the signals output from the plurality of amplifiers 400. The combining unit 500 outputs the combined signal to an antenna (not shown) via a coaxial cable (not shown) or the like.

  The transmission operation of the transmission device has been described above.

  Next, the cooling operation of the transmission apparatus 100 will be described using the drawings. The cooling operation of the transmission device 100 is performed in parallel with the above-described transmission operation. Arrows α <b> 1 to α <b> 5 in FIG. 4 are arrows indicating the traveling direction of air inside the housing 200. The arrows in FIG. 5 are arrows that indicate the direction of air travel in the transmission device 100.

  First, the intake fan 220 sucks air outside the housing 200 into the housing 200. Specifically, the intake fan 220 takes air outside the housing 200 into the intake ventilation portion 210 from the intake port 215. The air that has flowed into the intake ventilation portion 210 flows into the housing portion 203 through the through hole of the intake partition plate 205. The air that has flowed into the storage unit 203 includes heat from the plurality of power supply units 300, the plurality of amplification units 400, and the combining unit 500, and then travels from the intake partition plate 205 side to the exhaust partition plate 225 side.

  At this time, a part of the air (air traveling in the direction of the arrow α1 in FIG. 4) from the intake partition plate 205 side to the exhaust partition plate 225 side is left in the gap X (of the plurality of power supply units 300). It goes to the exhaust port 235 after passing through a gap between them. As a result, each of the plurality of power supply units 300 is cooled. Further, a part of the air (air proceeding in the direction of the arrow α2 in FIG. 4) from the intake partition plate 205 side to the exhaust partition plate 225 side becomes a gap Y (each of the plurality of amplifying units 400). And go to the exhaust port 235. Thereby, each of the plurality of amplifying units 400 is cooled. Further, a part of the air (air proceeding in the direction of arrow α3 in FIG. 4) from the intake partition plate 205 side to the exhaust partition plate 225 side is blocked by the synthesis unit 500, and in the direction of arrow α4 in FIG. After branching into the advancing air and the advancing air in the direction of α5 in FIG. Thereby, the synthetic | combination part 500 is cooled.

  And the air in the accommodating part 203 flows into the ventilation part 230 for exhaust_gas | exhaustion through the through-hole of the partition plate 225 for exhaust_gas | exhaustion. The air flowing into the exhaust ventilation section 230 is exhausted out of the housing 200 through the exhaust port 235. Specifically, the air in the exhaust ventilation section 230 is exhausted out of the housing 200 by the exhaust fan 240 through the exhaust port 235.

  As described above, in the transmission device 100, air outside the housing 200 is sucked into the housing 200 through the air inlet 215, and then passes through the gap X and the gap Y from the exhaust port 235 to the outside of the housing 200. Exhausted. At this time, the air passing through the gap X and the gap Y includes exhaust heat of the plurality of power supply units 300, the plurality of amplification units 400, and the combining unit 500. Therefore, the air exhausted from the exhaust port 235 to the outside of the housing 200 includes exhaust heat from the plurality of power supply units 300, the plurality of amplification units 400, and the synthesis unit 500. As a result, the plurality of power supply units 300, the plurality of amplification units 400, and the synthesis unit 500 are cooled by the air outside the housing 200.

  The operation of the transmission device 100 has been described above.

  As described above, the transmission device 100 described in the present embodiment includes the housing 200, the plurality of amplification units 400, and the synthesis unit 500. Further, the housing 200 includes an intake port 215 and an exhaust port 235. The plurality of amplifying units 400 are disposed on the front side of the housing 200 and are provided so as to overlap each other with a gap Y therebetween. The combining unit 500 is disposed on the back side of the plurality of amplification units 400 so as to face each of the plurality of amplification units 400, and combines signals output from each of the plurality of amplification units 400. The air inlet 215 is provided on one side surface of the housing 200 and is provided for sucking air outside the housing 200 into the housing 200. The exhaust port 235 is provided on the other side surface facing one side surface of the housing 200, and is provided for discharging the air outside the housing 200 sucked by the air intake port 215 to the outside of the housing 200. In addition, the air blower 250 is configured to allow the air outside the housing 200 to be sucked in through the air inlet 215 so that the air outside the housing 200 flows from one side of the housing 200 to the other side through the gap Y. Is exhausted from the exhaust port 235. The combining unit 500 is arranged such that the surface having the smallest area among the surfaces constituting the outer shape of the combining unit 500 is directed to one side surface side.

  As described above, the combining unit 500 is arranged so that the surface having the smallest area among the surfaces constituting the outer shape of the combining unit 500 faces one side surface. An intake port 215 is provided on one side surface of the housing 200. Therefore, the smallest surface of the synthesis unit 500 is arranged toward the windward side. As a result, the amount of air (air traveling in the direction of arrow α3 in FIG. 4) blocked by the combining unit 500 among the air sucked from the air inlet 215 provided on one side surface is minimized. I can do it. As a result, the amount of air (the air traveling in the direction of the arrow α4 in FIG. 4 and the air traveling in the direction of the arrow α5 in FIG. 4) that changes the traveling direction can be minimized by being blocked by the combining unit 500. Therefore, it is possible to suppress the retention of air from the intake port 215 toward the exhaust port 235. In addition, it is possible to prevent the air flow from the intake port 215 toward the exhaust port 235 from being disturbed. As a result, air smoothly flows from the intake port 215 to the exhaust port 235. As a result, in the transmission device 100, the inside of the housing 200 can be cooled more efficiently.

  In addition, in the transmission apparatus 1000 illustrated in FIGS. 10 to 12, the combining unit 5000 is arranged such that the widest surface constituting the outer shape of the combining unit 5000 is directed to the windward side. For this reason, in the transmission apparatus 1000, the amount of air (air traveling in the direction of the arrow p1 in FIG. 10) blocked by the combining unit 5000 is large. Therefore, the amount of air toward the back side (the direction indicated by the arrow p2 in FIG. 10) and the amount of air toward the front side (the direction indicated by the arrow p3 in FIG. 10) increase. As a result, in the transmitting apparatus 1000, the air in the housing 2000 does not flow smoothly from the intake port 2150 to the exhaust port 2350, and thus the inside of the housing 2000 cannot be cooled more efficiently.

  On the other hand, as described above, in transmitting apparatus 100, air that changes the traveling direction by being blocked by combining unit 500 (air that travels in the direction of arrow α4 in FIG. 4 and air that travels in the direction of arrow α5 in FIG. 4). ) Can be minimized. As a result, in the transmission device 100, the air in the housing 200 flows smoothly from the intake port 215 to the exhaust port 235, so that the inside of the housing 200 can be cooled more efficiently than the transmission device 1000 described above. .

  The transmission device 100 of this embodiment includes a plurality of power supply units 300. The plurality of power supply units 300 are arranged on the back side of the plurality of amplifying units 400 and are provided so as to overlap each other with a gap X therebetween. In addition, each of the plurality of power supply units 300 is connected to each of the plurality of amplification units 400.

  As described above, the plurality of power supply units 300 are provided inside the housing 200 so as to overlap each other with the gap X interposed therebetween. The plurality of power supply units 300 are cooled by air from the intake port 215 toward the exhaust port 235. On the other hand, the air from the intake port 215 toward the exhaust port 235 can pass through the gap X. Therefore, this allows air to flow smoothly from the intake port 215 to the exhaust port 235. As a result, in the transmission device 100, the inside of the housing 200 can be more efficiently cooled even when the plurality of power supply units 300 are provided.

  The combining unit 500 of the transmission device 100 according to the present embodiment is disposed between the plurality of amplification units 400 and the plurality of power supply units 300.

As described above, the synthesis unit 500 is disposed between the plurality of amplification units 400 and the plurality of power supply units 300. The combining unit 500 is arranged such that the surface having the smallest area among the surfaces constituting the outer shape of the combining unit 500 faces one side surface. Accordingly, when the combining unit 500 is disposed between the plurality of amplification units 400 and the plurality of power supply units 300, the front side surface of the plurality of amplification units 400 and the rear side surface of the plurality of power supply units 300. The distance between can be shortened. Therefore, the housing 200 can be made small. As a result, the transmission device 100 can be reduced in size.

  As described above, in the transmitting device 100A, air outside the housing 200 is sucked into the housing 200 through the air inlet 215, and then exhausted from the exhaust port 235 to the outside of the housing 200 through the gap X. . At this time, the air passing through the gap Y includes heat from the plurality of amplifying units 400 and the combining unit 500. Thereby, the plurality of amplifying units 400 and the combining unit 500 are cooled by the air outside the housing 200.

  The operation of transmitting apparatus 100A has been described above.

  As described above, the transmission device 100 </ b> A described in the present embodiment includes the housing 200, the plurality of amplification units 400, and the synthesis unit 500. Further, the housing 200 includes an intake port 215 and an exhaust port 235. The plurality of amplifying units 400 are disposed on the front side of the housing 200 and are provided so as to overlap each other with a gap Y therebetween. The combining unit 500 is disposed on the back side of the plurality of amplification units 400 so as to face each of the plurality of amplification units 400, and combines signals output from each of the plurality of amplification units 400. The air inlet 215 is provided on one side surface of the housing 200 and is provided for sucking air outside the housing 200 into the housing 200. The exhaust port 235 is provided on the other side surface facing one side surface of the housing 200, and is provided for discharging the air outside the housing 200 sucked by the air intake port 215 to the outside of the housing 200. In addition, the air blower 250 is configured to allow the air outside the housing 200 to be sucked in through the air inlet 215 so that the air outside the housing 200 flows from one side of the housing 200 to the other side through the gap Y.

An intake port 215 is provided on one side surface of the housing 200. Therefore, the smallest surface of the synthesis unit 500 is arranged toward the windward side. This minimizes the amount of air (air traveling in the direction of arrow β1 in FIG. 7) blocked by the combining unit 500 among the air sucked from the air inlet 215 provided on one side surface. I can do it. Accordingly, the amount of air that changes the traveling direction (air traveling in the direction of arrow β2 in FIG. 7 and air traveling in the direction of arrow β3 in FIG. 7) can be minimized by being blocked by the combining unit 500. Therefore, it is possible to suppress the retention of air from the intake port 215 toward the exhaust port 235. In addition, it is possible to prevent the air flow from the intake port 215 toward the exhaust port 235 from being disturbed.
