Description

  The present invention relates to a radar apparatus, and more particularly to a radar apparatus having a heat dissipation structure.

  A radar device such as a phased array radar is known. The radar apparatus generates heat during operation and needs to be cooled. As a method of cooling the radar apparatus, there is a method of cooling the transmission / reception module by attaching a heat sink to the transmission / reception module and forming a flow path with a cylindrical body. For example, Japanese Unexamined Patent Application Publication No. 2004-180166 discloses a phased array antenna device. This phased array antenna apparatus includes a plurality of transmission / reception modules including a transmission / reception module body having a heat sink and a cylindrical body for housing the transmission / reception module body. In the phased array antenna apparatus, the plurality of transmission / reception modules are cascade-connected so that the cylinders of adjacent transmission / reception modules are hermetically sealed and cooling air can pass through the heat sink. A connecting body is formed.

  In this phased array radar apparatus, the transmission / reception module can secure a long and wide cooling surface in the antenna front-rear direction (direction connecting the front and rear of the antenna). However, when the antenna is a panel type in order to reduce the size of the radar apparatus in the longitudinal direction of the antenna, the cooling surface is only on the opposite side of the antenna surface. Therefore, it is considered that there is a limit to improving the ability to cool the transmission / reception module.

  In addition, as a method for cooling the transmission / reception module, it has been proposed to use an antenna as a heat sink in a portable device. For example, Japanese Patent No. 4269160 discloses an antenna structure of a portable terminal device. In the antenna structure of this portable terminal device, the antenna for wireless communication also serves as a heat sink for cooling the heat generating components on the printed circuit board. In the antenna structure of the portable terminal device, the antenna is in contact with the heat-generating component via a heat conductor that is an electrically defective conductor, and in an antenna housing portion that forms a printed circuit board housing portion and a small chamber of the device housing. It is arranged across.

  Since this antenna structure is for a cellular phone, it is a natural air-cooling, is a single heat sink, and does not particularly consider the flow path of the cooling medium. In addition, it does not consider replacing the transmission / reception module. In a radar apparatus such as a phased array radar, since the transmission / reception module is frequently exchanged, maintainability becomes a problem when this antenna structure is applied to the radar apparatus.

  As a related technique, Japanese Patent No. 4189278 discloses a structural member in which a piping system is integrated. The structural member integrated with this piping system is formed in a rectangular frame shape, and includes an outer frame unit having a first member corresponding to one side of the rectangular frame and a second member facing the first member, A plurality of cooling units, which are mounted between the first member and the second member of the outer frame unit and in which a first pipe for flowing a cooling medium is formed by a hollow structure. . In each of the first member and the second member, a second pipe for flowing the cooling medium is formed in a hollow structure, and an external pipe connected to the second pipe is coupled. And a plurality of pipe ports connected to the first pipe line provided in each of the plurality of cooling units. The tube opening provided in each of the first member and the second member and the end of the first conduit of the cooling unit are formed in a concave shape. Each of the first member and the second member is connected to both end portions of the cooling unit so that the portions formed in the concave shape coincide with each other. By connecting the pipe opening and the first pipe line, and connecting the cooling unit to each of the first member and the second member, a connecting member for preventing leakage of the cooling medium. A plurality of O-rings returned to the outer periphery of the connecting member are press-contacted to the pipe port portion and the inner peripheral surface of the first pipeline by being mounted on the formed concave portion.

  Hereinafter, a radar apparatus according to an embodiment of the present invention will be described using a phased array radar apparatus having a panel structure as an example. Hereinafter, a patch antenna will be described as an example of the radar device antenna. However, the present invention is not limited to the example, and can be applied to other antennas (example: dipole antenna, inverted F antenna).

(First embodiment)
The configuration of the radar apparatus according to the first embodiment of the present invention will be described.
FIG. 1 is a side view schematically showing a part of the configuration of the radar apparatus according to the present embodiment. This radar apparatus 1 is a panel array phased array radar apparatus. Here, description of the power supply wiring is omitted. The radar apparatus 1 includes a cooling unit 3, a plurality of transmission / reception modules 11, a casing 12, a plurality of antennas 15, a plurality of dielectrics 14, a radome 16, and a cooling medium supply unit 20. .

  The cooling unit 3 has, for example, a plate shape, and is in contact with the plurality of transmission / reception modules 11 on the surface on the + z side. The cooling unit 3 dissipates heat from the plurality of transmission / reception modules 11 and cools the plurality of transmission / reception modules 11 from the −z side. The cooling unit 3 has a plurality of pipes penetrating the inside, and is exemplified by a structure in which a cooling medium flows through the plurality of pipes (not shown).

  The transmission / reception module 11 has, for example, a thick plate shape or a rectangular parallelepiped shape, and is arranged in a matrix on the cooling unit 3. The transmission / reception module 11 is supplied with power from a power supply unit (not shown), supplied with a control signal from a power supply circuit (not shown), outputs a transmission signal to the antenna 15, and receives a reception signal from the antenna 15. The plurality of transmission / reception modules 11 are provided corresponding to the plurality of antennas 15, and are connected to the plurality of antennas 15. In other words, one transmission / reception module 11 is provided with one antenna 15 dedicated to the transmission / reception module 11, and the transmission / reception module 11 and the antenna 15 are connected to each other.

  The housing (frame) 12 has, for example, a plate shape, and is in contact with the plurality of transmission / reception modules 11 on the −z side (inside) surface of the housing 12. The housing 12 holds a plurality of transmission / reception modules 11 and determines their positions. In the present embodiment, the housing 12 is formed so as to be divided for each transmission / reception module 11. A packing 17 is inserted in the divided portion to maintain airtightness. Thereby, as will be described later, each transmission / reception unit 2 can be detached from the radar apparatus 1.

  The antenna 15 has a plate shape, for example, and is arranged in a matrix on the + z side (outside) of the housing 12 away from the housing 12. The antenna 15 preferably has a large surface area from the viewpoint of cooling. The antenna 15 is held away from the housing 12 by a support member 13 extending from the housing 12. The antenna 15 may be held in contact with the housing 12. The conducting wire 18 connected to the antenna 15 passes through the support member 13, penetrates the housing 12, and is connected to the transmission / reception module 11 corresponding to the antenna 15. In addition, you may serve as the conducting wire 18 by making the supporting member 13 into an electroconductive material. The antenna 15 emits a transmission signal from the conductor 18 as a transmission radio wave, and outputs a reception radio wave to the conductor 18 as a reception signal. The antenna 15 can radiate the heat of the transmission / reception module 11 received via the conductor 18 like a heat sink. The support member 13 is preferably made of a material having high thermal conductivity so as to function like a heat sink like the antenna 15.

  The dielectric 14 has, for example, a plate shape, and is arranged in a matrix on the housing 12 on the + z side (outside) of the housing 12. The dielectric 14 adjusts the characteristics of the antenna 15. The plurality of dielectrics 14 are provided corresponding to the plurality of antennas 15. In other words, one antenna 15 is provided with one dielectric 14 dedicated to the antenna 15. The dielectric 14 is preferably formed of a material having high thermal conductivity, for example. This is because the heat of the transmission / reception module 11 can also be released from the dielectric 14. Note that the dielectric 14 may be in contact with the antenna 15.

  The radome 16 has a plate shape, for example, and is in contact with the plurality of antennas 15 on the −z side (inner side) surface of the radome 16. In other words, the radome 16 is provided in contact with the + z side (outside) of the plurality of antennas 15 so as to cover the plurality of antennas 15. The radome 16 protects the plurality of antennas 15 from the outside while allowing transmission radio waves and reception radio waves related to the plurality of antennas 15 to pass therethrough. The radome 16 may be separated from the antenna 15.

  In the present embodiment, the radome 16 is formed to be separable for each transmission / reception module 11. A packing 17 is inserted in the divided portion to maintain airtightness. Thereby, as will be described later, each transmission / reception unit 2 can be detached from the radar apparatus 1. The radome 16 may be held by a plurality of antennas 15. Further, the radome 16 may be provided in the vicinity of the outside of the plurality of antennas 15 so as to be separated from the plurality of antennas 15.

  The cooling medium supply unit 20 supplies the cooling medium R to the flow path 4 formed between the radome 16 and the casing 12 (or between the plurality of antennas 15 and the casing 12). For example, when the radome 16, the antenna 15, the dielectric 14, and the housing 12 are in contact with each other, the dielectric 14 and the antenna 15 are adjacent to the dielectric 14 and between the radome 16 and the housing 12. A refrigerant flow path R is formed in a lattice shape so as to pass between the antenna 15 and the antenna 15. Further, when the radome 16 and the antenna 15 are separated from each other, a refrigerant flow path R is also formed between the radome 16 and the antenna 15. In addition, when the antenna 15 and the dielectric 14 are separated from each other, a refrigerant flow path R is also formed between the antenna 15 and the dielectric 14.

  The antenna 15 is cooled from the −z side (inner side) by the flow of the cooling medium R. Thereby, the heat generated in the transmission / reception module 11 can be dissipated from the antenna 15. That is, the antenna 15 can function as a heat sink. Further, the casing 12 and the dielectric 14 are cooled from the + z side (outside) by the flow of the cooling medium R. Thereby, the heat generated in the transceiver module 11 can be further dissipated from the housing 12 and the dielectric 14.

  The cooling medium supply unit 20 is exemplified by a configuration including a pipe 23, a heat exchanger 21, and a circulation device 22. The pipe 23 connects the outlet O and the inlet I of the cooling medium R in the radar apparatus 1. The heat exchanger 21 is provided in the middle of the pipe 23 and cools the heated cooling medium R. The circulation device 22 is provided in the middle of the pipe 23 and circulates the cooling medium R. The cooling medium R is exemplified by air or a nonconductive liquid (for example, ethylene glycol). When the cooling medium R is air, the cooling medium supply unit 20 may be an outside air feeding fan (not shown) provided at the inlet I or an outside air sending fan (not shown) provided at the outlet O. Good.

  Thus, in the radar apparatus 1 according to the present embodiment, the transmission / reception module 11 is cooled so as to be sandwiched between the cooling layer on the front side (+ z side) and the cooling layer on the rear side (−z side). . However, the cooling layer on the front side (+ z side) is a flow path 4 (cooling medium R; including heat radiation by the antenna 15) formed by the radome 16 and the housing 12. The cooling layer on the rear surface side (−z side) is the cooling unit 3. Thus, the transmission / reception module 11 can be efficiently cooled by cooling the transmission / reception module 11 from the front side and the rear side.

  FIG. 2 is a perspective view schematically showing a part of the configuration of the radar apparatus according to the present embodiment. Here, descriptions of the power supply wiring and the support member 13 are omitted. As described above, the plurality of transmission / reception modules 11, the plurality of antennas 15, and the plurality of dielectrics 14 are arranged in a matrix. In other words, the set of the transmission / reception module 11, the antenna 15, and the dielectric 14 is arranged in a matrix.

  The radome 16 is provided for each row of the matrix, and covers the antenna 15 and the dielectric 14 arranged in that row among the plurality of antennas 15 and the plurality of dielectrics 14. The cooling medium supply unit 20 supplies the cooling medium R between the radome 16 and the housing 12 for each row. Thereby, the cooling medium R flows along the line through the flow path formed by the radome 16 and the housing 12. Alternatively, the radome 16 is provided for each column of the matrix, and covers the antenna 15 and the dielectric 14 arranged in that column among the plurality of antennas 15 and the plurality of dielectrics 14. The cooling medium supply unit 20 supplies the cooling medium R between the radome 16 and the housing 12 for each row. Thereby, the cooling medium R flows along the row through a flow path formed by the radome 16 and the housing 12.

  In the example of this figure, the x direction is the row direction, the y direction is the column direction, and the radome 16 is provided for each row. The radome 16 covers the antennas 15 and the dielectrics 14 arranged along the rows of the plurality of antennas 15 and the plurality of dielectrics 14. The cooling medium supply unit 20 supplies the cooling medium R between the radome 16 and the housing 12 for each row. Thereby, the cooling medium R flows along the row in the flow path formed by the radome 16 and the housing 12 in the x direction.

  FIG. 3 is a side view schematically showing a part of the configuration of the radar apparatus according to the present embodiment. Here, description of the power supply wiring is omitted. In the radar apparatus 1, the housing 12 and the radome 16 are formed so as to be divided for each transmission / reception module 11. Therefore, the transmission / reception module 11, the casing 12p on the transmission / reception module 11 and its peripheral area, the antenna 15 and the dielectric 14 corresponding to the transmission / reception module 11, and the radome 16p on the antenna 15 and its peripheral area are provided. The transmitter / receiver unit 2 is integrated. In other words, the antenna 15, the transmission / reception module 11, the dielectric 14, the housing 12p, and the radome 16p are detachably provided as one transmission / reception unit 2. In this case, the antenna 15 is an antenna (first antenna) 15 which is an arbitrary one of the plurality of antennas 15. The transceiver module 11 is a transceiver module (first transceiver module) 11 corresponding to the first antenna 15 among the plurality of transceiver modules 11. The dielectric 14 is a dielectric (first dielectric) 14 corresponding to the first antenna 15 among the plurality of dielectrics 14. The casing 12p is a casing (first casing portion) 12p at a position corresponding to the first transmission / reception module 11 in the casing 12. The radome 16 p is a radome (first radome portion) 16 p at a position corresponding to the first antenna 15 in the radome 16. In the radar apparatus 1, a plurality of transmission / reception units 2 are arranged in a matrix.

  The transmission / reception unit 2 can be detached individually. Therefore, by removing the transmission / reception unit 2 from the front side (+ z side) of the antenna 15, the radome 16, the antenna 15, (dielectric 14), and the transmission / reception module 11 can be replaced together. Thereby, maintenance of the radar apparatus 1 can be easily performed.

  With respect to the direction in which the cooling medium R flows, the adjacent transmission / reception units 2 are connected by the packing 17 so that the cooling medium R does not leak. In the example of this figure, the adjacent transmission / reception unit 2-1 and transmission / reception unit 2-2 are connected by the packing 17 with respect to the direction in which the cooling medium R flows in the row direction (x direction) so that the cooling medium R does not leak. It has become. That is, airtightness between the transmission / reception units 2 is ensured by the packing 17.

Next, the operation of the radar apparatus according to this embodiment will be described.
When the radar apparatus 1 is used, the cooling medium supply unit 20 is turned on. Thereby, the cooling medium R flows along the flow path between the housing 12 and the radome 16. At the same time, the cooling unit 3 is also turned on. Thereby, the cooling medium flows through the flow path of the cooling unit 3.
On the other hand, when the radar apparatus 1 is used, the transmission / reception module 11 generates heat due to its operation, and the temperature rises. The heat is also transmitted to the antenna 15.
The cooling medium R flows along the flow path between the housing 12 and the radome 16, thereby depriving the antenna 15 (or the dielectric 14 or the housing 12) of heat. Thereby, the antenna 15 is cooled, and the transmission / reception module 11 is cooled from the + z side. At the same time, the cooling medium takes the heat of the transmission / reception module 11 by flowing through the flow path of the cooling unit 3. Thereby, the transceiver module 11 is cooled from the −z side.
As described above, the radar apparatus according to the present embodiment operates.

Next, the replacement operation of the transmission / reception unit 2 of the radar apparatus according to the present embodiment will be described.
In the radar apparatus 1, when a certain transmission / reception unit 2 (or the transmission / reception module 11 or the antenna 15) is malfunctioning, the radar apparatus 1 is first turned off. Subsequently, a predetermined jig is inserted from the front side (+ z side) of the antenna 15 into the packing 17 portions before and after the malfunctioning transmission / reception unit 2, and the transmission / reception unit 2 is extracted in the + z direction. Thereafter, another transmitting / receiving unit 2 prepared in advance is inserted from the front side (+ z side) of the antenna 15 to adjust the packing 17.
As described above, the transmission / reception unit 2 according to the present embodiment is replaced.

  As described above, in the present embodiment, in the radar device 1 (example: phased array radar device having a panel structure), the antenna 15 is provided away from the dielectric 14 and the housing 12. Accordingly, the antenna 15 can be used as a heat sink, and the heat of the transmission / reception module 11 can be radiated from the antenna 15.

  In the present embodiment, the antenna 15 can be forcibly cooled by forming a flow path with the casing 12 and the radome 16 and circulating the cooling medium R through the flow path. Accordingly, both the front surface (+ z side; antenna 15 side) of the transmission / reception module 11 and the rear surface (−z side; cooling unit 3 side) of the transmission / reception module 11 can be used for cooling. Thereby, the cooling area of the transmission / reception module 11 can be secured, and the cooling capability of the radar apparatus 1 can be improved.

  Furthermore, in this embodiment, the antenna 15 and the radome 16 can be cooled. Thereby, it is possible to cope with heat generation of the radome 16 due to an increase in transmission power (temperature rise can be suppressed). Moreover, since the noise of the antenna 15 can be reduced thereby, the minimum receiving sensitivity of the antenna 15 can be improved. That is, in the radar apparatus 1, it is possible to improve the reception capability of the antenna.

  Further, in the present embodiment, the transmission / reception unit 2 in which the transmission / reception module 11, the antenna 15, and the radome 16 are integrated is used. With such a transmission / reception unit 2 having an integral structure, the radome 16, the antenna 15, and the transmission / reception module 11 can be integrally taken out from the front side (+ z side) of the antenna 15 and can be exchanged integrally. That is, in the radar apparatus 1, maintainability can be improved.

(Second Embodiment)
The configuration of the radar apparatus according to the second embodiment of the present invention will be described.
The present embodiment is different from the first embodiment in that the transmission / reception module, the antenna, and the radome are not integrated, and the transmission / reception module, the antenna, and the radome are separated. In the following, differences will be mainly described.

  FIG. 4 is a side view schematically showing a part of the configuration of the radar apparatus according to the present embodiment. The radar apparatus 1a is a panel array phased array radar apparatus. Here, description of the power supply wiring is omitted. The radar apparatus 1a includes a cooling unit 3, a plurality of transmission / reception modules 11, a housing 12a, a plurality of antennas 15, a plurality of dielectrics 14, a radome 16a, and a cooling medium supply unit 20. .

  In the present embodiment, the housing 12 a is not divided for each transmission / reception module 11. Similarly, the radome 16 a is not divided for each transmission / reception module 11. Therefore, the transmission / reception unit 2a including the transmission / reception module 11, the dielectric 14, the antenna 15, and the radome 16a cannot be exchanged in units of transmission / reception units, unlike the first embodiment.

  The flow path 4 of the cooling medium R is formed by the radome 16a and the housing 12a as in the first embodiment. However, the flow path is separated from the transmission / reception module 11 by a housing 12a and has a different structure. In other words, the flow path 4 is a closed space formed by the radome 16a and the housing 12a, and the cooling medium R flows from the inlet I to the outlet O in the closed space. As a result, there is no problem that the cooling medium R leaks to the transmission / reception module 11 side when the transmission / reception module 11 is replaced. In this case, the transmission / reception module 11 is replaced, for example, by removing the outer (+ z side) configuration from the housing 12a.

  In this case, the radome 16a does not have to be provided for each row (or for each column) of the matrix of the transmission / reception module 11 and the antenna 15. For example, it may be provided every few rows or so as to cover the entire matrix. This simplifies the structure of the radome 16a and facilitates manufacture.

Also in this embodiment, the same effects as those of the first embodiment can be obtained.
Further, the transmission / reception module 11 and the front cooling layer of the flow path 4 are in heat conductive contact, and the cooling medium R does not leak to the transmission / reception module 11 side when the transmission / reception module 11 is replaced.

(Third embodiment)
A configuration of a radar apparatus according to the third embodiment of the present invention will be described.
This embodiment is different from the second embodiment in that a dielectric is positively used as a heat sink. In the following, differences will be mainly described.

  FIG. 5 is a side view schematically showing a part of the configuration of the radar apparatus according to the present embodiment. This radar device 1b is a phased array radar device having a panel structure. Here, description of the power supply wiring is omitted. The radar apparatus 1b includes a cooling unit 3, a plurality of transmission / reception modules 11, a casing 12b, a plurality of antennas 15, a plurality of dielectrics 14b, a radome 16b, and a cooling medium supply unit 20. .

  In the present embodiment, the dielectric 14b on the housing 12b has a heat sink shape, for example, a shape provided with a number of protruding fins provided to increase the heat transfer area. The dielectric 14b is preferably made of a material having a low dielectric constant and high thermal conductivity from the viewpoint of its function. Thereby, the antenna 15 and the dielectric 14 can be used as an antenna and heat sink. At this time, the shape of the antenna 15 needs to be optimized in order to radiate radio waves. However, by using a material having high thermal conductivity as the dielectric 14b, the performance of the antenna 15 can be reduced without deteriorating the performance. The performance can be improved. And the heat | fever of the transmission / reception module 11 can be thermally radiated from the front side of the transmission / reception module 11 more efficiently.

  Moreover, since the dielectric 14b has a heat sink shape, air cooling by natural ventilation is possible instead of forced cooling. In that case, it is preferable that the radome 16b is set apart from the antenna 15 to some extent or the radome 16b is not provided. This is to promote natural ventilation. Thereby, the cooling medium supply part 20 can be made unnecessary. The transceiver module 11 can be cooled from the + z side by the heat sink effect of the dielectric 14b and the heat sink effect of the antenna 15 provided away from the housing 12b and the dielectric 14b.

  Such a shape having a large number of protruding fins can also be applied to the dielectric 14 of the first embodiment.

  Even if the dielectric 14b has the same shape as that of the dielectric 14 of the first embodiment, when there is no radome 16b or when the radome 16b is sufficiently away from the antenna 15, natural ventilation is used. Only by air cooling, the heat of the transceiver module 11 can be dissipated to some extent. This is because the heat sink effect of the antenna 15 provided apart from the housing 12b and the dielectric 14b acts effectively, although the heat sink effect of the dielectric 14b is reduced.

Also in this embodiment, the same effects as those of the second embodiment can be obtained.
In addition, the heat of the transceiver module 11 can be radiated more efficiently without degrading the performance of the antenna 15. Furthermore, depending on the design of the dielectric 14, the cooling medium supply unit is not necessary, and the configuration can be simplified.

  Each embodiment has been described by taking a flat patch antenna as an example of the antenna 15. However, the present invention is not limited to this example, and can be applied to other antennas. For example, a rod-shaped antenna such as a dipole antenna or an inverted F antenna can be used as the antenna 15.

  As described above, in the radar device according to each of the above embodiments, the cooling capacity can be improved. In addition, it is possible to improve the cooling capacity and improve maintainability. In addition, it is possible to improve the cooling capacity and improve the receiving capacity of the antenna.

  The present invention is not limited to the embodiments described above, and it is obvious that the embodiments can be appropriately modified or changed within the scope of the technical idea of the present invention.
