Description

  The present invention is used as an attached pod of a navigation body such as an aircraft, and particularly relates to a pod for a navigation body that efficiently dissipates heat generated from an electronic device installed in the attached pod.

  Conventionally, this type of navigation pod is installed on the aircraft body when it must be added in addition to the electronic devices and other accessories mounted on the aircraft body. In order to achieve this, it is necessary to consider heat dissipation against heat generated from the installation space and equipment. Therefore, as an accessory device of the aircraft body, these electronic devices can be accommodated by installing a navigation pod separate from the aircraft body, and storing and installing electronic devices with heat dissipation in the navigation body pod. It is made like that.

  As a conventional pod for this type of navigation body, an independent cooling device is installed inside the pod to absorb heat dissipation from the electronic equipment during operation as needed, preventing an abnormal temperature rise of the electronic equipment. There are known devices that maintain the reliability of devices (see, for example, Patent Document 1).

  FIG. 7 is a schematic view showing a cross section of a part of a conventional navigation pod 1 (Patent Document 1).

  The navigation pod 1 shown in FIG. 7 absorbs heat (self-heating component) from the electronic device 3 side with respect to the electronic device 3 installed in the pod wall 2 and passes through the pod wall 2. A cooling device 4 capable of exchanging heat with the outside air A flowing outside the lever wall 2 is provided.

  The cooling device 4 includes a first heat exchanger 5 that directly absorbs a heat component radiated from an electronic device 3 side installed at an arbitrary position (not shown) in the pod wall body 2 with a refrigerant, and a heat component that has exchanged heat. , A second heat exchanger 7 for radiating heat components contained in the high-pressure liquid refrigerant adiabatically compressed by the compressor 6, and a second heat exchanger 7 for radiating heat. The high-pressure liquid refrigerant is adiabatically expanded in the first heat exchanger 5 and is returned to the first cycle, and the expansion valve 8 is configured to absorb the heat component radiated from the electronic device 3 side.

In the cooling device 4 configured in this way, the better the heat exchange efficiency by the first heat exchanger 5 and the second heat exchanger 7, the more efficiently the heat component with respect to the heat radiation from the electronic device 3. Can be absorbed.
JP 2001-97285 A

  According to the conventional navigation body pod 1, the heat component radiated from the electronic device 3 side is radiated to the outside of the pod wall 2 by the cooling device 4, so that the electronic device 3 suppresses an abnormal temperature rise due to self-heating. However, when the cooling device 4 is installed in the pod wall 2, since the device becomes large, the navigation pod 1 can be prevented. As a result, the overall size of the aircraft increased in size, and there was a risk of adversely affecting the safety and navigation stability during navigation.

It is formed in a size that can be taken in. The body wall 13a of the hollow body portion 13 has a predetermined thickness t, and the electronic device 14 is provided within the thickness t.

  Reference numeral 17a denotes an opening portion 11a provided on a side surface portion of the body wall 13a of the hollow body portion 13 and is attached so that the electronic device 14 can be attached to and detached from the body wall 13a side from the opening portion 11a side. Reference numeral 17 denotes an opening / closing lid which is attached to the opening 11a so as to be freely opened and closed. The opening / closing lid 17 is attached so that the navigation body pod 10 is not dropped when the navigation body pod 10 is mounted on the navigation body and subjected to vibration or wind pressure during navigation.

  Further, the hollow body portion 13 is provided with a plurality of, for example, three support columns 13b having substantially the same length from the body wall 13a side to the cylindrical space portion a side, and the central body 16 is supported at the distal ends of these support columns 13b. Is provided.

  As shown in FIGS. 3 and 4, the electronic device 14 is installed on the side close to the cylindrical space part a in the body wall 13 a of the hollow body part 13.

  The heat exchanger 15 includes a plate-like heat conduction base 18 thermally conductively joined to the plate-like surface of the electronic device 14, and the plate-like surface of the heat conduction base 18 and the plate-like surfaces of the electronic device 14.

Further, the heat exchanger 15 is provided with a radiation fin 19 projecting toward the cylindrical space part a, and the heat can be radiated to the cylindrical space part a side of the hollow body part 13 through the radiation fin 19. It has become. Specifically, as shown in FIG. 4, the heat dissipating fins 19 are configured so that flat fin portions 19 a are provided in a layered manner in the cross-sectional direction of the cylindrical space portion a of the pod body 11.

It is provided so as to obtain a rectifying action of the outside air x.

  Next, the operation of the navigation pod 10 will be described with reference to FIGS.

  In the navigation body pod 10, a plurality of electronic devices 14 operate during navigation of the navigation body. When the plurality of electronic devices 14 operate, a heat generation (self-heating) action peculiar to the plurality of electronic devices 14 occurs. The generated heat is radiated from a plurality of radiating fins 19 through a heat conduction base 18 thermally conductively joined to the plurality of electronic devices 14. And as for this heat dissipation, outside air x is taken in into the cylindrical space part a of the hollow trunk | drum 13, for example, when it moves to the arrow y direction, as shown in FIG.

  Next, the action of the outside air x taken into the cylindrical space part a of the hollow body part 13 and passing through the cylindrical space part a will be described in detail.

  The outside air x passing through the cylindrical space portion a of the hollow body portion 13 is different from the navigation direction (arrow y direction) of the navigation body shown in FIG. Outside air x is taken in. In such a case, even when the air volume or direction of the outside air z flowing in the cylindrical space portion a changes, the change in the wind pressure received by the entire navigation body pod 10 due to the rectifying action of the outside air x of the center fuselage 16 is achieved. Little affected. Therefore, the air volume and the wind pressure of the outside air z taken into the cylindrical space portion a of the hollow body portion 13 do not change greatly, and the outside air x that is about to pass through the cylindrical space portion a is stably exchanged with the heat exchanger 15. The heat exchange is performed on.

  In this way, by the stable heat exchange with respect to the electronic device 14 by the heat exchanger 15, the navigation body equipped with the navigation body pod 10 is in a normal navigation state, or turns, or even a typhoon. It is possible to adjust the adverse influence on the navigation of the wind pressure received as a navigational object in the navigation under the environment where such an abnormal wind pressure is received.

  According to the pod 10 for navigation bodies, the pod main body 11 provided with the hollow body part 13 which formed the cylindrical space part a, the electronic device 14 arrange | positioned at the body wall 13a of the hollow body part 13, and the inside of the body wall 13a Provided with the heat exchanger 15 that dissipates the heat generated from the electronic device 14 to the cylindrical space portion a, and therefore within the range of the cylindrical space portion a where the heat exchanger 15 is provided. By increasing the density of the heat exchanger 15 (increasing the heat dissipation area), the heat dissipation performance can be further improved. Therefore, it is possible to eliminate the large-scale cooling device used in the conventional navigation pod.

  In addition, since the heat generation component of the electronic device 14 can be efficiently radiated using the heat exchanger 15 in the tubular space portion a using the passing outside air x, the navigation body pod 10 is used. The overall size can be reduced in size and weight.

  Further, on the outer peripheral surface of the pod main body 11, there are provided an opening 11a having a size capable of attaching and removing the electronic device 14 installed in the pod main body 11, and an opening / closing lid 17 provided so that the opening 11a can be opened and closed.

Since the center body 16 is provided along the longitudinal direction of the cylindrical space portion a with a predetermined interval from the a side inner wall, the size of the heat radiation portion of the heat exchanger 15 is While the size of the space a can be within the range, the size can be reduced, and the heat dissipation density (heat dissipation area) can be increased to further improve the heat dissipation performance.

  In addition, since the center body 16 is provided in the cylindrical space portion a of the hollow body portion 13 with a required distance from the inner wall on the cylindrical space portion a side of the hollow body portion 13, the navigation body is being navigated. The outside air x passing through the cylindrical space portion a is stabilized in air volume and direction by the rectifying action of the central body 16, and the heat dissipation performance of the heat exchanger 15 can be stably maintained in a highly efficient state. Therefore, the large-scale cooling device used for the conventional navigation pod can be eliminated.

  Further, according to the navigation pod 10, since no special cooling device is required, the entire navigation pod 10 can be reduced in size and weight, and the entire navigation pod 10 can be manufactured at low cost. can do.

[Second Embodiment (FIGS. 5 and 6)]
Next, a navigation pod 20 according to a second embodiment of the present invention will be described with reference to FIGS. 5 and 6 in which the same reference numerals are assigned to the same parts as those in FIGS.

  FIG. 5 is a partial longitudinal sectional view corresponding to FIG. 4 described above, showing an outline of the navigation pod 20 of the present invention. FIG. 6 is a cross-sectional view corresponding to FIG. 3 described above, showing an outline of the pod 20 for a navigation body of the present invention.

  As shown in FIG. 5, the navigation pod 20 shown in FIGS. 5 and 6 includes a cylindrical pod body 21, and leg portions 12 provided to attach the pod body 21 to the bottom of the navigation body (not shown). It has.

  The pod body 21 includes a hollow body portion 23 in which a cylindrical space portion a is formed, and a plate-like electronic device that is installed in the hollow body portion 23 as shown in FIG. A heat exchanger 25 that is thermally conductively bonded to the plate-like surface of the electronic device 24 and radiates a heat component (self-heating component) generated in the electronic device 24 toward the cylindrical space a; It is comprised from the center trunk | body 26 which made the fluid shape supported by the hollow trunk | drum 23 side and was provided in the cylindrical space part a.

  The central body 26 is supported by two support columns 23b provided in the hollow body part 23, and is provided so as to be positioned at the approximate center of the cylindrical space part a. Further, the central body 26 is disposed along the longitudinal direction of the cylindrical space portion a, and both end portions thereof are formed in a streamline shape. The central body 26 is provided with an electronic device 24 and a heat exchanger 25 on the side where the support body 23b for supporting the central body 26 is not provided, that is, on the upper side in FIG.

  The heat exchanger 25 is provided integrally with the heat conduction base 28 that is thermally conductively joined to the electronic device 24, and protrudes toward the cylindrical space portion a. It comprises a plurality of radiating fins 29 provided.

  As shown in FIG. 5, the plurality of radiating fins 29 are provided with a plurality of flat fin portions 29 a, and the plurality of flat fin portions 29 a are located in front of the hollow body portion 23, that is, the navigation pod 20. It is provided so that the longitudinal direction is directed along the navigation direction (the y direction in the drawing).

  As shown in FIGS. 5 and 6, the heat conduction base 28 is installed such that the back surface side is thermally conductively joined to the electronic device 24 and the front surface side faces the cylindrical space a side. A plurality of heat radiation fins 29 are integrally provided on the surface side of the heat conduction base 28 in a thermally conductive manner.

  The other configuration of the navigation pod 20 is the same as the configuration of the navigation pod 10 and will not be described.

  Next, the operation of the navigation pod 20 will be described with reference to FIGS.

  In the navigation body pod 20, a plurality of electronic devices 14 provided on the hollow body 23 side and a plurality of electronic devices 24 provided on the central body 26 side operate during navigation of the navigation body. When these electronic devices 14 and 24 are operated, a heat generation (self-heating) action occurs in the plurality of electronic devices 14 and 24. The generated heat is radiated from a plurality of radiating fins 19 and 29 via heat conduction bases 18 and 28 that are thermally conductively joined to the plurality of electronic devices 14 and 24, respectively. Then, as shown in FIG. 5, in this heat radiation, outside air x is taken into the cylindrical space portion a of the hollow body portion 23 when the navigation body moves in the direction of the arrow y, for example.

  The action of the outside air x taken in and passing through the outside space x of the hollow space 23 will be described in detail.

  The outside air x passing through the cylindrical space portion a of the hollow body portion 23 is stably taken into the pod main body 21 from the direction of the arrow y shown in FIG. 5 when the navigation body navigates, for example, in normal weather. Thus, the heat radiation from the heat exchangers 14 and 24 is absorbed by the outside air x with high efficiency and released outside the cylindrical space portion a. On the other hand, the wind pressure of the outside air x may be applied to the navigation body from a direction different from the navigation direction.

  For example, when the navigation body itself turns in the air, or depending on weather conditions such as a typhoon, the wind direction in the air differs from the navigation direction of the navigation body, the pod body 21 is affected by wind pressure from a direction other than the navigation direction. Will receive. The influence of this wind pressure is related to the overall size of the hollow body part 23. That is, for example, when wind pressure more than expected is applied to the hollow body portion 23 side, the wind pressure received by the navigation body itself increases, which hinders stable navigation.

  Therefore, the navigation pod 20 can be made smaller and lighter, so even when the wind pressure from the direction different from the navigation direction of the navigation body or wind pressure stronger than expected of the outside air x is received. , The influence of the wind pressure on the navigational situation is small. Accordingly, the navigation body equipped with the navigation pod 20 is not only in a normal navigation state, but also as a navigation body for navigation under an environment in which it turns or is subjected to abnormal wind pressure such as a typhoon. Can sail to.

  Further, since the outside air x passing through the cylindrical space portion a of the hollow body portion 23 of the navigation body pod 20 has a rectifying action by the wall surface facing the cylindrical space portion a side of the hollow body portion 23, it is tubular. Heat exchange efficiency can be further improved by appropriately increasing the installation density of the radiation fins 19 and 29 of the heat exchangers 15 and 25 provided in the space a.

  According to the navigation body pod 20, the pod body 21 including the hollow body portion 23 in which the cylindrical space portion a is formed, the electronic device 24 disposed on the body wall 23 a of the pod body 21, and the body wall 23 a A heat exchanger 25 that dissipates heat from the electronic device 24 to the cylindrical space a side, and a cylindrical space a side of the hollow body 23 that is provided in the cylindrical space a part of the pod body 21. A central body 26 is provided along the longitudinal direction of the cylindrical space portion a with a predetermined distance from the inner wall, and the electronic device 24 is installed in the central body 26, so that the central body 26 is separated from the central body 26. In addition, since the heat generation from the electronic device 24 can be dissipated to the cylindrical space portion a, the large-scale cooling device used in the conventional navigation pod can be eliminated.

  Further, the pod body 21 is provided with a cylindrical space portion a, and the outside air x is allowed to pass through the cylindrical space portion a, and at the same time, the heat generation components of the electronic devices 14 and 24 are heated by using the passing outside air x. Since the heat radiation can be efficiently radiated using the exchangers 15 and 25, the size of the navigation pod 20 as a whole can be reduced in size and weight. As a result, the entire navigation pod 20 can be manufactured at low cost.

  Furthermore, on the outer peripheral surface of the pod body 21, an opening 11a having a size capable of attaching and removing the electronic device 24 installed in the pod body 21 and an opening / closing lid 17 provided so that the opening 11a can be opened and closed are provided. Since it is provided, the assembly and disassembly workability of the navigation pod 20 is improved. In particular, it is possible to improve the workability of attaching and detaching electronic devices that require parts replacement and function check.

  In addition, although the radiation fins 19 and 29 of the heat exchangers 15 and 25 provided in the navigation body pod 10 and the navigation body pod 20 according to the embodiment of the present invention are flat, this shape is used. In order to improve the heat exchange efficiency by increasing the surface area, for example, a waved shape can be used.

  Furthermore, as shown in FIGS. 1 to 4, each of the openings 11 a of the hollow body portions 13 and 23 provided in the navigation body pod 10 and the navigation body pod 20 according to the embodiment of the present invention is an electronic device. 14 and 24 are exemplified for only one place, but the configuration may be such that the opening / closing lid 17 is provided for the other electronic devices 14 and 24 side.
