Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a ventilation and cooling device for ventilating an occupant compartment of a combat vehicle and further cooling an electronic device mounted on the occupant compartment, and in particular, an occupant. The present invention relates to a ventilation and equipment cooling device for a passenger compartment, which is suitable for a combat vehicle in which equipment is installed close to a passenger compartment.

(Prior Art) A fighting vehicle requires a large number of control devices such as electronic devices. Many of such control devices generate internal heat. Moreover, since electronic devices generally do not like moisture, salt, dust, etc., they are usually housed in a sealed box. Therefore, the inside of the box that accommodates those electronic devices is likely to become hot. On the other hand, in order to make the electronic devices operate accurately, it is necessary to keep the electronic devices in a certain temperature range. Therefore, in combat vehicles, it is necessary to provide a device cooling device for cooling such devices.

For cooling such equipment, generally, a heat absorption passage is provided on a side portion of a box in which electronic equipment and the like are housed, air is circulated between the heat absorption passage and the inside of the box, and the heat absorption passage is adjacent to the heat absorption passage. An indirect air cooling system is used in which an air duct is arranged and outside air is flowed through the air duct to radiate heat (see, for example, JP-A-63-133556). In that case, since it is necessary to force the outside air to flow through the air duct, a blower is used for the device cooling device.

On the other hand, even in combat vehicles, it is necessary to ventilate the passenger compartment in order to improve habitability. Blowers are also used for ventilation.

In a conventional battle vehicle, a trailing vehicle is provided separately from the battle vehicle in which passengers appear, and the trailing vehicle is equipped with electronic devices and the like. Therefore, the ventilation device for the passenger compartment and the cooling device for the equipment are provided separately.

(Problems to be solved by the invention) However, in such an electronic device mounted on a trailing vehicle, not only a vehicle is required separately from the combat vehicle but also personnel for operating the trailing vehicle are required. Will be needed. Further, there is a problem that the mobility of the battle vehicle is hindered or the confidentiality is lowered due to the accompanying vehicle when the operation is deployed.

For this reason, it is required that electronic devices and the like be mounted on combat vehicles. For that purpose, it is necessary to install an equipment cooling device in the battle vehicle in addition to the passenger compartment ventilation device.

In that case, the space in the passenger compartment should be as wide as possible. In addition, if the outer contour of a battle vehicle becomes large, it becomes a strategic problem from the viewpoint of elasticity, etc. Therefore, the outer contour should be made as compact as possible. Therefore, the passenger compartment ventilation device and the equipment cooling device are required to be as compact as possible.

On the other hand, when the electronic device is mounted on the battle vehicle, the space in the passenger compartment is inevitably narrower than that of the conventional separate vehicle type. Moreover, since the electronic device is arranged close to the passenger compartment, the temperature inside the passenger compartment is likely to become high due to the heat generated by the electronic device. Therefore, it is necessary to ventilate the passenger compartment more strongly.
That is, it is necessary to use a large capacity blower for ventilation. Therefore, it is difficult to make the blower compact by providing the blower and the equipment cooling blower separately.

It is possible to introduce the air to the equipment cooling device by a ventilation blower that discharges the air in the passenger compartment.
Combat vehicles are often placed in an atmosphere containing toxic gas or bacteria or in a high dust environment.In such an environment, the outside air intake and exhaust vents for occupant ventilation are closed. In such a case where the blower blows air to the equipment cooling device, the equipment cannot be cooled in such a case.

The present invention has been made in view of such a problem, and an object thereof is a compact ventilation system for a passenger compartment, which has a large ventilation capacity for the passenger compartment, and can always cool the equipment. Is to get.

(Means for Solving the Problem) In order to achieve this object, in the present invention, an outside air intake for ventilation that takes in outside air into the passenger compartment and an exhaust vent for ventilation that exhausts the air inside the passenger compartment to the outside by a ventilation blower. In addition to the above, an inside air intake opening that opens in the passenger compartment and can open and close to extract the air inside the passenger compartment is provided, and the inside air intake outlet is made to communicate with the equipment cooling air duct via the switching device. . The switching device connects the inside air outlet with the equipment cooling air duct when the inside air outlet is open, and when the inside air outlet is closed, the emergency outside air intake is provided outside the passenger compartment. And the device cooling air duct. The device cooling air duct is provided with a device cooling blower for flowing air through the air duct. Further, the ventilation outside air intake and the ventilation exhaust port of the passenger compartment are opened and closed by an opening / closing damper or the like.

(Operation) In the passenger compartment ventilation and equipment cooling device configured as described above, normally, the ventilation outside air intake, the ventilation exhaust outlet, and the inside air outlet of the passenger compartment are all opened, and the ventilation blower and equipment are Both cooling blowers are driven. Therefore, the outside air is taken into the passenger compartment through the outside air intake, and the air inside the passenger compartment is discharged and discharged through the exhaust opening and the inside air intake opening. That is, the passenger compartment is ventilated by the two blowers, the ventilation blower and the equipment cooling blower, and sufficient ventilation is provided.

Further, the air in the passenger compartment sucked from the inside air outlet is guided to the equipment cooling air duct. Therefore, the electronic device and the like are also cooled reliably.

On the other hand, in an atmosphere containing toxic gas, bacteria, etc., the ventilation outside air intake port, the ventilation exhaust port, and the inside air intake port of the passenger compartment are all closed. Therefore, toxic outside air is prevented from flowing into the passenger compartment. And at this time,
The equipment cooling air duct communicates with the emergency outside air intake,
The outside air is made to flow from the outside air inlet to the air duct by the blower for cooling the equipment. Therefore, also at this time, the device is surely cooled.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a combat vehicle equipped with a passenger compartment ventilation and equipment cooling device according to the present invention. FIG. 1 is a partially cutaway side view of the combat vehicle, and FIG. FIG. 3 is a partially cutaway plan view and rear view, respectively.

As is clear from these figures, the battle vehicle 1 is provided with an endless track device 2 for traveling and a turret 3 supported by the endless track device 2. The interior of the turret 3 is airtightly divided by a partition wall 4 into a front passenger compartment 5 and a rear equipment room 6.

An upper portion of the passenger compartment 5 is provided with a ventilation outside air intake 7 for taking in outside air. The outside air intake 7 is opened and closed by an inward opening type opening / closing damper 8. In addition, a ventilation exhaust port 9 that opens to the side surface is provided in the lower portion of the passenger compartment 5. The exhaust port 9 is also opened and closed by an inward opening type opening / closing damper 10. The exhaust port 9 is provided with a ventilation blower 11 capable of discharging the air in the passenger compartment 5 when the damper 10 is open. The blower 11 is driven by the power of the vehicle 1.

An inside / outside air switching chamber 12 is provided in an upper portion of the equipment chamber 6 adjacent to the partition wall 4. The upper wall of the inside / outside air switching chamber 12 is provided with an emergency outside air intake 13 capable of taking in outside air. The partition 4 forming one side wall of the inside / outside air switching chamber 12 is provided with an inside air outlet 14 that opens into the passenger compartment 5. The inside air outlet 14 is opened and closed by a switching damper 15. Then, when the inside air intake port 14 is opened, the switching damper 15 comes into close contact with the stopper 16 provided on the side wall of the inside / outside air switching chamber 12 facing the partition wall 4 so that the emergency outside air intake port 13 is sealed. It has become.

On the bottom wall of the inside / outside air switching chamber 12, via the inside / outside air suction port 17,
One end of an equipment cooling air duct 18 is connected. The other end of this air duct 18 is used as an equipment cooling exhaust port 19 that opens to the outside of the vehicle body, and a device cooling blower 20 provided at the exhaust port 19 allows the air sucked from the inside / outside air intake port 17 to flow. The air is discharged from the exhaust port 19 through the air duct 18. The blower 20 is always driven by the power of the vehicle 1.

In this way, when the switching damper 15 is operated to open the inside air outlet 14, the inside air outlet 14 and the inside / outside air intake 17 of the air duct 18 communicate with each other, and the air in the passenger compartment 5 becomes the equipment cooling air. When the intake air is sucked into the duct 18 and the inside air intake port 14 is closed by the switching damper 15, the outside air intake port for emergency
The inside and outside air intake ports 17 communicate with each other so that the outside air is drawn into the device cooling air duct 18. That is,
In this embodiment, a switching damper 15 connects an opening / closing device for opening / closing the inside air outlet 14 and an inside / outside air inlet 17 of the air duct 18 to either the emergency outside air inlet 13 or the inside air outlet 14. And a switching device for selectively switching.

In the equipment room 6, a plurality of boxes 21, 21, ... Having a completely sealed structure in which control electronic equipment is incorporated are housed. A heat absorption passage 22 is provided on a side portion of each box 21, adjacent to the outer peripheral surface of the equipment cooling air duct 18, and in which air is circulated with the inside of the box 21. Then, the heat in the heat absorption passage 22 is radiated into the air flowing in the air duct 18, and the electronic device in the box 21 is cooled. The structure of such an equipment cooling unit is described in the above-mentioned Japanese Patent Laid-Open No. 63-63.
Since a known structure as shown in Japanese Patent Publication No. 133556 may be used, detailed description thereof will be omitted.

On the other hand, in the passenger compartment 5, a plurality of boxes 23, 23 each containing an electronic device are installed by utilizing the dead space or the like. In order to cool the inside of the box 23, a second device cooling air duct 24 having a device cooling section similar to the device cooling air duct 18 in the device chamber 6 is provided. Both ends of the air duct 24 are both in the passenger compartment 5
Is opened to the outside, one end of which is an intake port 25 for sucking outside air, and the other end of which is an exhaust port 26 for discharging the sucked air. At its outlet 26, the air duct 24
A second device cooling blower 27 is provided to allow air to flow therethrough. This blower 27 is also always driven by the power of the vehicle 1.

Next, the operation of the passenger compartment ventilation and the equipment cooling device thus configured will be described.

Under a normal atmosphere where no toxic gas or bacteria is present in the outside air, the ventilation outside air intake 7 and the ventilation exhaust port 9 of the passenger compartment 5 are kept open. Further, the inside air outlet 14 is also kept open by rotating the switching damper 15 in the direction in which it comes into contact with the stopper 16.

In this state, when the ventilation blower 11 and the equipment cooling blower 20 are driven, the air in the passenger compartment 5 is discharged from the ventilation exhaust port 9 and is sucked out from the inside air outlet 14 to cool the equipment cooling air. It is discharged to the outside from the exhaust port 19 through the duct 18. Then, air corresponding to the discharged air amount flows into the passenger compartment 5 from the outside air intake 7. In this way, ventilation in the passenger compartment 5 is performed.

In this way, since the ventilation in the passenger compartment 5 is performed by the two blowers 11 and 20, sufficient ventilation is achieved even if the capacity of each of the blowers 11 and 20 is small. Also, ventilation exhaust port 9
The device cooling air duct 18 may have a small diameter. Therefore, they can be compact.

Further, the air sucked out from the passenger compartment 5 flows through the air duct 18, so that a heat absorption passage is provided in the equipment cooling section.
Heat is exchanged with the hot air in 22,22. Then, the cooled air in the heat absorption passage 22 is guided to the box 21, whereby the electronic equipment housed in the box 21 is cooled. On the other hand, the electronic device housing box 23 installed in the passenger compartment 5 is cooled in the same manner by the second device cooling blower 27 being driven and the outside air flowing through the second device cooling air duct 24. To be done.

In this way, the passenger compartment 5 is ventilated and the devices are cooled.

In an emergency when toxic gas and bacteria are present in the external atmosphere, the ventilation outside air intake 7 and the exhaust port 9 of the passenger compartment 5 are closed by open / close dampers 8 and 10, respectively. Also, the inside air outlet 14
Is also closed by the switching damper 15. Therefore, the passenger compartment 5 is in a hermetically sealed state, and harmful inflow of outside air is prevented.

In this way, when the inside air outlet 14 is closed by the switching damper 15, the inside / outside air inlet 17 of the equipment cooling air duct 18 communicates with the emergency outside air inlet 13. Therefore, by driving the equipment cooling blower 20, the air duct 18
The outside air is sucked into and is discharged from the exhaust port 19. And
The air thus flowing through the air duct 18 cools the electronic devices housed in the boxes 21, 21.

On the other hand, also in this case, the electronic device housing boxes 23, 23 installed in the passenger compartment 5 are cooled by the outside air flowing through the second device cooling air duct 24. Since the inside of the air duct 24 and the inside of the passenger compartment 5 are completely isolated from each other, there is no possibility that outside air will flow into the passenger compartment 5 at this time.

In this way, the electronic device is reliably cooled even when the passenger compartment 5 is sealed. Therefore, the correct operation can be ensured. At this time, the ventilation blower 11 is stopped. That is, at this time, only the small-capacity device cooling blowers 20 and 27 are driven, so that energy saving can be achieved.

In the above embodiment, the air in the passenger compartment 5 does not flow through the air duct 24 that cools the equipment installed in the passenger compartment 5. However, the air duct for cooling the equipment in the equipment compartment 6 is not provided. Similar to 18, the intake port 25 can be switched so as to communicate with the inside and outside of the passenger compartment 5, and the second equipment cooling blower 27 can also perform ventilation in the passenger compartment 5. That way, the ventilation blower
The capacity of 11 can be further reduced.

Further, in the above embodiment, when the internal air intake port 14 is opened, the emergency outside air intake port 13 is supposed to be completely closed by the switching damper 15, but it is possible to make it a half open state, It is also possible to mix the air in the passenger compartment 5 and the outside air into the equipment cooling air duct 18 and allow them to flow in.

Furthermore, the opening / closing of the inside air outlet 14 and the switching of the communication state of the inside / outside air inlet 17 can be performed by separate valves or the like.

(Effects of the Invention) As is apparent from the above description, according to the present invention, ventilation of the passenger compartment is performed not only by the ventilation blower but also by the equipment cooling blower. It can have a relatively small capacity. Therefore, even when an electronic device is installed near the passenger compartment of a battle vehicle, it is not necessary to use a large-sized ventilation blower, so that the passenger compartment space is secured, and the operability of the passenger and the living environment are improved. It is possible to improve the property.

Also, when the passenger compartment is closed, the outside air is taken into the equipment cooling air duct, so even in an atmosphere containing toxic gas, bacteria, etc. Can be kept at
