Description

  The present invention relates to a cooling device for a battery for traveling of a vehicle.

  A large-capacity traveling battery is mounted on a vehicle such as an electric vehicle, a hybrid vehicle, and a fuel cell vehicle that is driven by a motor. Such a traveling battery obtains a high voltage by connecting a large number of lead storage batteries, nickel metal hydride batteries, lithium ion batteries and the like in series.

  Generally, a plurality of (for example, six) battery cells (for example, six battery cells having an output voltage of 1.2 V) are connected to and integrated with the battery for traveling so as to obtain a necessary power capacity (voltage value). A collective secondary battery (battery module) that is configured to be connected to each other is often used. A predetermined number of such battery modules are further connected in series to form a traveling battery having a high voltage output of 200V to 300V.

  The battery for running generates heat due to a chemical reaction generated inside the battery cell. If this heat generation is left, problems such as a reduction in battery capacity and a reduction in battery life occur. For this reason, when the module is incorporated in the battery for traveling, a gap is provided for the air passage as a cooling medium, and air in the vehicle compartment is sent to the gap by a cooling fan for cooling. As described above, the air in the passenger compartment is used for cooling the battery for traveling because the air in the passenger compartment does not contain water droplets such as rain. Even when the temperature is high, the low-temperature air in the passenger compartment can be used as cooling air, and the cooling efficiency can be improved.

  FIG. 11 shows a cooling structure for the traveling battery 16 according to the prior art. The traveling battery 16 is installed in the lower rear part of the rear seat 12 of the vehicle 10. A battery module 20 is disposed in the traveling battery 16 with a gap, and cooling air for the traveling battery 16 passes from the intake port 130 provided on the side of the rear seat 12 to the cooling fan through the intake conduit 122. After being sucked into 126 and pressurized by the cooling fan 126, it is fed into the traveling battery 16. The cooling air sent into the traveling battery 16 flows through the gaps in the battery module 20 to cool the battery module 20 and is discharged out of the vehicle 10 from the exhaust pipe 24 (see, for example, Patent Document 1).

  As described above, the cooling structure that sucks the air in the vehicle interior by the cooling fan 126 and sends it to the traveling battery 16 may cause the noise of the cooling fan 126 to spread in the vehicle interior and cause discomfort to the passengers. For this reason, the cooling air intake 130 of the traveling battery 16 is proposed to be located as far as possible from the occupant (see, for example, Patent Document 2), or a sound absorbing material is disposed in the intake pipe 122 to cool the battery. Proposals have been made so that fan noise does not spread in the passenger compartment (see, for example, Patent Document 1).

JP-A-2005-71759 JP 2003-306045 A

  However, in the cooling structure for the traveling battery 16 according to the prior art, since the air intake 130 is fixedly disposed in the vehicle interior, the passenger at a position away from the air intake 130 does not feel that the noise is so great. Even if the noise of the cooling fan 126 is such a level, there is a problem that the occupant in the position near the air inlet 130 feels a considerable noise, and the occupant feels uncomfortable. Further, when an occupant is seated near the air inlet 130, the occupant spills liquid on the air inlet 130, etc., so that moisture is contained in the cooling air, leading to a reduction in the life of the traveling battery 16. In addition, there is a problem that the cooling performance is deteriorated due to the intake port 130 being blocked by an occupant.

  In view of the above, an object of the present invention is to reduce occupant discomfort caused by cooling fan noise by separating the position of the intake port and the seating position of the occupant. Another object of the present invention is to improve the protection of the traveling battery by preventing moisture from entering the traveling battery.

  A traveling battery cooling device of the present invention is a traveling battery cooling device for a vehicle that takes in air from an air intake in a vehicle and ventilates the traveling battery by a cooling fan to cool the traveling battery. It has an intake port variable mechanism which changes the position of an intake port based on the seating state acquired by the seating state acquisition means.

  Here, the air intake variable mechanism has an air intake box that has an air intake on one side and a connection line connected to a cooling fan on the other side along a guide fixed in the vehicle width direction inside the vehicle. Intake air that extends in the width direction of the vehicle provided on one surface of the air intake box that is fixed inside the vehicle and connected to the connection pipe line with the cooling fan may be moved by the driving means. A shutter having an intake window may be moved by the driving means along the mouth. Further, the intake port variable mechanism may change the intake port position to the intake port command position acquired from the intake port position control logic table data based on the detected seating state.

  The drive mechanism of the intake variable mechanism is a means for screwing a ball screw attached to the inside of the vehicle rotatably into a ball nut attached to the outer surface of the intake box and rotating the ball screw with a drive motor. Also good.

  A traveling battery cooling device of the present invention is a traveling battery cooling device for a vehicle that takes in air from an air intake in a vehicle and ventilates the traveling battery by a cooling fan to cool the traveling battery.

It is also preferable that the intake port position is changed to the intake port command position acquired from the intake port position control logic table data, and the control unit controls the cooling fan operation control logic table based on the detected seating state. It is also preferable to change the operation of the cooling fan to the command operation acquired from the data.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a first embodiment of a traveling battery cooling device of the present invention, and FIG. 2 is a side sectional view of a hybrid vehicle equipped with the traveling battery cooling device of the present invention.

  As shown in FIGS. 1 and 2, the traveling battery 16 is installed in the lower rear portion of the rear seat 12 of the vehicle 10, and the battery module 20 is disposed in the traveling battery 16 with a gap. An intake box casing 36 is fixed to the vehicle 10 behind the rear seat 12. Two guides 38 are fixed to the bottom of the inner surface of the intake box casing 36 in the width direction of the vehicle 10. On the guide 38, an intake box 32 to which wheels 37 running on the guide 38 are rotatably attached is disposed. The intake box 32 has an intake port 30 having a lattice-shaped opening for taking in air on the upper surface, and an intake pipe (connection pipe) 22 is connected to the lower surface, and the width of the vehicle 10 along the guide 38. It can move in the direction. A ball nut 33 is fixed to the outer surface of the intake box 32, and a ball screw 34 rotatably attached to the intake box casing 36 is screwed into the ball nut 33. The ball screw 34 is connected to a drive motor 48 fixed on the outer surface of the intake box casing 36, and the rotation of the drive motor 48 moves the intake box 32 fixed to the ball nut 33 along the guide 38 in the width direction of the vehicle 10. It can be moved freely. An intake pipe (connection pipe) 22 attached to the lower surface of the intake box 32 is an intake box that moves freely in the width direction of the vehicle 10 and the cooling fan 26 fixed to the upper part of the intake box 32 and the traveling battery 16. It is a bendable pipe line such as a bellows pipe that can be freely deformed and connected to the pipe 32. The discharge port of the cooling fan 26 is connected to one end face of the traveling battery 16, and the exhaust pipe 24 is attached to the other end face of the traveling battery 16. Further, in the intake box casing 36, three intake port position sensors 46a to 46c for detecting the position of the intake box 32, that is, the position of the intake port 30, are attached. Further, three seating sensors 40 a to 40 c for detecting whether or not an occupant is seated are attached to the seating surface of the rear seat 12.

  The cooling air of the traveling battery 16 enters the intake box 32 through the intake port 30 and is sucked into the cooling fan 26 through the intake duct (connection duct) 22. And the battery module 20 is cooled, and then discharged from the exhaust pipe 24 to the outside of the vehicle 10.

  The battery cooling device for traveling configured as described above detects the seating position of the occupant by the seating sensors 40a to 40c of the rear seat 12, and the drive motor 48 and the ball so that the intake port 30 is positioned away from the occupant. The position is changed by the drive means by the screw 34 and the ball nut 33. The control of the intake port variable mechanism is performed by the following control device 50.

  As shown in FIG. 3, the control device 50 controls signals from the seating sensor interfaces 52 a to 52 c and the inlet position sensors 46 a to 46 c that input the signals of the control unit 51 and the seating sensors 40 a to 40 c to the control unit 51. Inlet position sensor interfaces 54a to 54c input to the unit 51, a drive motor interface 56 that inputs and outputs drive signals of the drive motor 48, and command position data of the intake port 30 with respect to the seating position of the occupant. A storage unit 57 storing a control logic table and a data bus 58 for transmitting these input / output data are provided.

  As shown in FIG. 4, the control logic table stored in the storage unit 57 sets the seating state as to whether the occupant is seated at the seating position, the seating state as 1, and the seating state as 0. It is acquired as a numerical signal, and an optimal intake port command position is output from a combination of seating state signals of three seats. The numbers of the seating position and the inlet position are 3 on the left side of the vehicle 10, 2 on the center, and 1 on the right side. For example, when the occupant is seated only in the rightmost seat position 1 and no occupant is seated in the other seats, the seating state signals are 0, 0, and 1. In this case, the intake port command position is 3, that is, the leftmost position farthest from the occupant's seating position.

  The operation of the control device for the intake port variable mechanism will be described with reference to the control flowchart of the control device 50 for the intake port variable mechanism in FIG.

  As shown in steps S101 to S102 of FIG. 5, when the ignition key is turned on and the vehicle 10 is activated, the control unit 51 acquires a seating state signal of the occupant from the seating sensors 40a to 40c. The acquired seating state signal is input to the control unit 51 from the seating sensor interfaces 52a to 52c. Further, as shown in step S103 of FIG. 5, the control unit 51 acquires the initial position when the intake port 30 is activated from the intake port position sensors 46a to 46c.

  As shown in step S <b> 104 of FIG. 5, the control unit 51 acquires intake port command position data from the control logic table in the storage unit 57 based on the seating state signal acquired in step S <b> 102.

  As shown in steps S105 to S108 in FIG. 5, the control unit 51 represents both the current position and the command position of the intake port 30 as integer values of 1 to 3, and thus by taking the difference between the two integers, It is determined whether the intake port position should be moved to the left or right. Thereby, when the numerical value of (current position−command position) is a positive numerical value, the control unit 51 rotates the drive motor 48 in the positive direction to move the intake box in the left direction of the vehicle. Conversely, when the numerical value of (current position−command position) is a negative numerical value, the control unit 51 rotates the drive motor 48 in the reverse direction to move the intake box to the right. Then, when the numerical value of (current position−command position) is 0, the control unit 51 does not need to change the intake port position and does not drive the drive motor 48.

  As shown in steps S109 to S111 in FIG. 5, the control unit 51 starts rotation of the drive motor 48 and then acquires intake port position data by the intake port position sensors 46a to 46c. The position of the intake port is changed by the drive motor 48 until. The control unit 51 stops the drive motor 48 when the intake port 30 comes to a predetermined position.

  As shown from step S112 to step S102 in FIG. 5, when the vehicle 10 is in the activated state, the control unit 51 obtains the seating position again and follows the intake port command position in the control logic table. , Change the inlet position.

  For example, at the time of initial seating state acquisition, there is no occupant in the rear seat 12, the input signals from the seating sensors 40a to 40c to the control unit 51 are 0, 0, 0, and the command inlet position is 1 from the control logic table. If the occupant is seated at position 1 of the rightmost rear seat after the intake port 30 is positioned on the rightmost side and the next seating state is acquired, as shown in step S102 of FIG. The input signals from the seating sensors 40a to 40c to the control unit 51 are 0, 0, 1, and the command intake port position is 3 from the control logic table. Then, the numerical values of steps S105 and S106 (current position−command position) in FIG. 5 become positive when 3−1 = 2, and the drive motor 48 starts to rotate in the positive direction so as to move the intake port 30 to the left. Then, as shown in steps S109 to S111 of FIG. 5, when the intake port position (intake box position) moves to the leftmost position 3, which is the command intake port position, the drive motor 48 stops. In this way, the seating position of the occupant is constantly monitored during the start of the vehicle, and the intake port position is controlled to change to the intake port command position in the control logic table.

  As shown in step S113 of FIG. 5, when the ignition key is turned OFF and the vehicle is stopped, the intake port variable control is also stopped.

  In the first embodiment, the position of the intake box 32 having the intake port 30 can be moved to a position away from the detected seating position of the occupant, thereby reducing occupant discomfort due to cooling fan noise. There is an effect that can be. Further, since the seating position of the occupant and the position of the intake port 30 can be separated, the possibility that the occupant spills liquid on the intake port 30 or blocks the intake port 30 is reduced. Thus, it is possible to prevent a decrease in life due to water entering 16 and a decrease in cooling performance due to a shortage of intake air amount, and it is possible to more reliably protect the traveling battery.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Parts similar to those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted. As shown in FIG. 6, in the present embodiment, not only the rear seat 12 but also the front seat has a seating sensor, and the control unit 51 acquires seating states of all seats of the front seat and the rear seat 12. It is configured to be able to. One front seat seating sensor 81a, 81c is provided for each of the right and left seats of the front seat. Each sensor may be provided on the seat of the seat and may directly detect the seating state, or may be detected by a seat belt wearing sensor. Similarly to the previous embodiment, seating sensors 82a to 82c are also attached to the right, center and left seats of each rear seat 12. Each of the seating sensors 82a to 82c of the rear seat 12 may be a seating sensor that directly detects the seating state as described above, or may detect the seating state by a seatbelt wearing sensor as in the case of the front seat. Further, the seating state of the rear seat 12 as a whole may be detected by a display for the rear seat 12 or an air conditioning switch on the rear seat 12 side.

  As shown in FIG. 6, the control device 50 includes seating sensor interfaces 83 a, 83 c, 84 a to 84 c that input signals from the control unit 51 and seating sensors 81 a, 81 c, 82 a to 82 c to the control unit 51, and intake port position sensors. Inlet position sensor interfaces 54 a to 54 c for inputting signals from 46 a to 46 c to the control unit 51, a drive motor interface 56 for inputting and outputting drive signals of the drive motor 48, and the operation of the cooling fan motor in the cooling fan motor 85. A cooling fan motor interface 86 that inputs and outputs signals, a storage unit 57 that stores a control logic table that is command position data of the intake port 30 with respect to the arrangement of the seating position of the occupant, and these input and output data And a data bus 58 for transmission.

  FIG. 7 shows a control logic table stored in the storage unit 57. This control logic table combines three tables (a) to (c) according to the seating state of the front seat and the seating state of the rear seat 12. As in the case of the rear seat 12, the seating state of the front seat is acquired as a numerical signal in which the seating state is 1, and the seating state is 0. The seating position numbers are 3 on the left side of the vehicle 10 and 1 on the right side. In FIG. 7A, 1 on the right side of the front seat is 1 indicating the seated state, and 0 indicating that the left 3 seat is not seated. That is, in the table of FIG. 7A, when the occupant is seated only in the right seat among the front seats, the command position of the intake port is output based on the seated state of the occupant of the rear seat 12. Each control table in FIG. 7 also outputs an operation command for the cooling fan motor 85 at the same time as the command position of the intake port. The number of the command value of the cooling fan motor 85 indicates a percentage with respect to the rated rotational speed, where 100 is the rated rotational speed and 80 is the rotational speed that is 80% of the rated rotational speed. As described above, the output command to the cooling fan motor 85 may use the rotation speed of the cooling fan motor 85 as a command value, or may use the output of the cooling fan motor such as kW as a command value.

  As shown in FIG. 7A, for example, in the state where the occupant is seated only in the right seat of the front seat and the occupant is not seated in the rear seat 12, the signal of the seated state of the front seat is: 0, 1 and the signal of the seating state of the rear seat 12 is 0, 0, 0. In this case, the intake port command position is 3, that is, the leftmost position 3 from the occupant seated on the right side of the front seat. The rotational speed of the cooling fan motor 85 is 100, that is, the rated rotational speed, and the cooling capacity is increased.

  When the occupant is seated only on the right side of the front seat and the occupant is seated only on the right side of the rear seat 12, the seating state signal of the rear seat 12 is 0, 0, 1, and the center of the rear seat 12 The seating signal when the occupant is seated only at 0 is 0, 1, 0. In either case, the intake port position is controlled to be on the left side. When the occupant is in the rear seat 12 as described above, the position of the intake port 30 is controlled so as to be determined by the seating position of the occupant in the rear seat. In addition, the rotation speed of the cooling fan motor 85 is set to 80%, and control is performed so as not to cause discomfort to the occupant of the rear seat 12.

  When the occupant is seated only on the right side of the front seat, the occupant is seated on the left and right of the rear seat 12, and the occupant is not seated in the center, the seat position signal of the rear seat 12 is 1, 0, 1 In this case, the position of the intake port 30 is the center position 2 so that the seat of the rear seat 12 is far from each occupant. Further, the rotation speed of the cooling fan motor 85 is set to 80% so as not to give uncomfortable feeling to the occupant of the rear seat 12. The same applies to the case where an occupant is seated on the left and right and the center of the rear seat 12.

  FIG. 7B shows the intake port position and the rotational speed command value of the cooling fan motor 85 in a state where an occupant is seated only on the left side of the front seat. As shown in FIG. 7B, when the occupant is seated only on the left side of the front seat and the occupant is not seated on the rear seat 12, the position of the intake port 30 is the occupant on the left side of the front seat. The cooling fan motor 85 is set to 100 and the cooling capacity is increased. When the occupant is on the right side of the rear seat 12, the signal of the seating position of the rear seat 12 is 0, 0, 1, and in this case, the intake port position is the leftmost position 3 from the occupant of the rear seat 12.

  As described above, the position of the intake port 30 is controlled so that the minimum distance from the occupant seated on the rear seat 12 is maximized in the seated state of the rear seat 12. If the minimum distance between the intake port 30 and the occupant does not change no matter what the intake port position is, the distance between the occupant seated on the front seat and the intake port 30 is maximized. The intake port position is changed so that the intake port 30 comes to the position. That is, the position of the intake port 30 is preferentially determined by the seating state of the rear seat 12, and when there are two or more candidates for the position of the intake port 30 depending on the seating state of the rear seat 12, the intake port 30 depends on the seating state of the front seat. Is determined. When an occupant is seated on the rear seat 12, the rotational speed of the cooling fan motor is slower than the rated rotational speed. When no occupant is seated on the rear seat 12, the cooling fan motor 85 is rated. It is configured to rotate at a rotational speed. That is, the rotational speed of the cooling fan motor 85 is determined by whether or not an occupant is seated on the rear seat 12.

  When the occupant is seated on the left and right sides of the front seat as shown in FIG. 7C, the position of the intake port and the number of rotations of the cooling fan motor are determined based on whether the rear seat 12 is seated and whether the rear seat 12 is seated. It is controlled so that the minimum distance to the passenger is maximized. When the occupant is seated only in the rightmost seat position 1 of the rear seat 12 and no occupant is seated in the other seats, the seating state signals are 0, 0, and 1. In this case, the intake port command position is 3, that is, the leftmost position 3 from the seating position of the occupant of the rear seat 12. When an occupant is seated in the center of the rear seat 12, the same applies to the left and right intake port positions for the occupant of the rear seat 12, and therefore, control is performed so that the position 1 is on the right side in the control logic table.

  The operation of the control device for the intake variable mechanism will be described with reference to the flowchart of FIG. 8 for the control of the control device 50 for the variable intake mechanism of FIG.

  As described above with reference to FIG. 5, as shown in steps S <b> 201 to S <b> 211 of FIG. 8, when the ignition key is turned on and the vehicle 10 is activated, the control unit 51 causes the seating sensors 81 a, 81 c, A passenger's seating state signal is acquired from 82a-82c, and the initial position at the time of starting of the inlet 30 is acquired from the inlet position sensors 46a-46c. Then, the control unit 51 acquires intake port command position data from the control logic table in the storage unit 57 based on the seating state signal acquired in step S202, and sets the intake port position by the drive motor 48 to the command position. The operation to change to is performed.

  As shown in step S212 of FIG. 8, the controller 51 determines the number of rotations of the cooling fan motor 85 according to the seating state signal from the control logic table described in FIG. Alternatively, an output is acquired and a drive command for the cooling fan motor 85 is output to the cooling fan motor 85. As a result, the cooling fan motor 85 rotates at the commanded rotational speed.

  As shown from step S214 to step S202 in FIG. 5, when the vehicle 10 is in the activated state, the control unit 51 obtains the seating position again, and follows the intake port command position in the control logic table. , Change the inlet position.

  For example, when the initial seating state is acquired, the rear seat 12 has an occupant, the input signals from the seating sensors 82a to 82c to the control unit 51 are 0, 0, 1, and the command intake port position is 3 from the control logic table. When the occupant of the rear seat 12 gets off the vehicle when the next sitting state is acquired after the mouth 30 is located on the leftmost side, as shown in step S202 of FIG. The input signal from 82c to the controller 51 is 0, 0, 0, and the command inlet position is 3 from the control logic table. For this reason, although the position of the intake port 30 does not change, since no occupant is seated on the rear seat 12, the drive command value of the cooling fan motor 85 is 80 to 100 when the occupant is seated on the rear seat 12. Increases cooling capacity.

  As shown in step S215 of FIG. 8, when the ignition key is turned OFF and the vehicle is stopped, the intake variable control is also stopped. In the second embodiment, the same effects as in the previous embodiments can be obtained.

  Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 9 is a side sectional view of the intake port variable mechanism of the third embodiment. In the third embodiment, the intake box 60 is fixed to the rear of the rear seat 12 in the vehicle 10 so that the longitudinal direction is the width direction of the vehicle 10, and the intake pipe connected to the cooling fan 26 at the lower part. A (connection pipe line) 22 is attached, and an intake port 30 is provided on the upper surface of the intake box 60 along the longitudinal direction (the width direction of the vehicle 10). The intake port 30 is provided with an intake window frame 62 having an intake window 61 that is an opening for sucking air. A shutter 65 is attached to both sides of the intake window frame 62 in the longitudinal direction of the intake box, and the intake port 30 is It is blocked. The shutter 65 is formed by connecting a plurality of shutter plates 66 by a shutter hinge 67, and a traveling wheel 72 is fitted into a shutter guide rail 70 provided along a peripheral portion of the intake box, and then along the shutter guide rail 70. And bendable. A pinion gear 64 for driving the intake window frame is attached to the intake window frame 62 so as to be rotated by a drive motor 48 (not shown). The pinion gear 64 meshes with a rack gear 68 fixed inside the intake box 60 so that the position of the intake window frame 62 (intake window 61) relative to the intake box 60 can be changed by the rotation of the pinion gear 64. It has become.

  The intake port position sensors 46a to 46c for detecting the position of the intake window 61 are attached to the intake box 60, and are driven and controlled by the same intake port variable mechanism control device as described in the first embodiment. In the third embodiment, the same effect as that of the first embodiment is obtained, and since the intake box 60 and the cooling fan 26 are both fixed to the vehicle 10, the intake pipe that connects between them is provided. Since the path (connection pipe line) 22 does not need to have a variable shape like the bellows duct, it is possible to reduce the pressure loss of the intake pipe line and to increase the cooling efficiency. .

  Next, a fourth embodiment of the present invention will be described with reference to FIG. Parts similar to those of the above-described embodiment are denoted by the same reference numerals and description thereof is omitted. FIG. 10A shows the configuration of the traveling battery 16 installed on the rear side of the rear seat 12, the cooling fan 26 of the traveling battery 16, and the intake ducts 91 a and 91 c to the cooling fan 26. In the present embodiment, the left and right intake ducts 91a and 91c are used as intake passages 91a and 91c for guiding the intake air from the intake ports 30a and 30c provided on the left and right to the cooling fan 26. A switching valve 93 is provided for changing the intake flow path so as to guide air. In the present embodiment, as described above, when there is an output of the command position of the intake port from the control unit 51, the switching valve 93 is switched so as to configure the intake flow path from the intake port position. For example, when the command position of the intake port is the position 1 on the right side, the switching valve 93 sucks air from the right intake port 30a and configures an intake flow path from the right intake duct 91a to the cooling fan 26. Move to the left. When the intake port position is set to the left position 3, the switching valve 93 is moved to the right side, and the intake air flow in which air is sucked into the cooling fan 26 from the left intake port 30c through the left intake duct 91c. Form a road. Further, when the intake command position is the central position 2, the switching valve 93 is moved to the neutral position, and air is sucked from both the right and left intake ports 30a and 30c. The present embodiment has an effect that the discomfort of the occupant due to the cooling fan noise can be reduced by separating the position of the intake port and the seating position of the occupant.

  FIG. 10B shows a fifth embodiment of the present invention. The same parts as those in the previous fourth embodiment are denoted by the same reference numerals, and the description thereof is omitted. The present embodiment has three right, center, and left intake ports 30a, 30b, and 30c and right and left intake ducts 91a and 91c. A partition valve 95a is provided between the intake port 30a and the intake duct 91a, and a partition valve 95c is provided between the intake port 30c and the intake duct 91c, and the right and left intake ducts 91a and 91c. A gate valve 95b is provided between the merging point and the intake port 30b. Each of the gate valves 95a to 95c opens and closes the air flow between the intake ports 30a to 30c and the intake ducts 91a and 91c by opening and closing the valves. Change to a flow path. For example, when the command position of the intake port is the position 1 on the right side, the gate valve 95a is opened to suck in air from the right intake port 30a and configure an intake flow path from the right intake duct 91a to the cooling fan 26. The gate valves 95b and 95c provided at the central and left intake ports 30b and 30c are closed to prevent air from being sucked from the intake flow paths 30b and 30c. Thus, the noise of the cooling fan 26 can be prevented from propagating into the passenger compartment. When the intake port position is set to the left side position 3, conversely, the gate valves 95b and 95a are closed, the left gate valve 95c is opened, and the cooling fan 26 passes through the left air intake duct 91c from the air inlet 30c. An air intake passage through which air is sucked is formed. Further, when the intake command position is the central position 2, the gate valves 95a and 95c are closed, the central gate valve 95b is opened, and air is sucked from the central air inlet 30b. This embodiment also has the same effect as the fourth embodiment.

  In the embodiment of the present invention, the traveling battery cooling device is described as being disposed behind the rear seat 12 at the rear of the vehicle 10, but the position of the traveling battery cooling device is not limited to the rear seat. Further, the seating sensors 40a to 40c, 81a, 81c, and 82a to 82c may be disposed anywhere other than the rear seat 12 and the front seat as long as they are seating positions corresponding to the intake port 30. Further, the present invention can be applied not only to a hybrid vehicle but also to an electric vehicle and a fuel cell vehicle equipped with a traveling battery.
