  As shown in FIG. 1, a car stereo main body case 1 is attached so that a front panel 2 thereof is substantially flush with an instrument panel 3 of a vehicle. The inside of the main body case 1 is configured by a structure such as a plurality of (two in FIG. 1) substrate units 7 on which the DVD mechanical unit 4, the tuner unit 5, and the electronic component 6 are mounted. Further, on the back side inside the main body case 1, a board 8, a connector 9 attached thereto, an air cooling fan 10 using an axial fan, and a cable attachment connector 11 for pulling out a cable for attachment to a vehicle-side power harness. Etc. are arranged. Some car stereo models are provided with other structures such as a monitor driving unit.

  In such in-vehicle electrical equipment such as a car stereo and a car navigation system, the above-described structures are incorporated in the main body case 1 so as to be three-dimensionally overlapped with each other. The inner space is occupied by the density. In addition, electronic parts 6 such as ICs and LSIs that generate a large amount of heat are scattered in the main body case 1, and many electronic parts 6 take measures for cooling them.

  FIG. 1 shows an example in which an air cooling fan 10 using an axial fan is arranged on the back side of the main body case 1.

  Hereinafter, the best embodiment of the present application will be described with reference to the accompanying drawings. Each embodiment described below applies the present application to a car stereo and car navigation as an electronic device mounted in the vehicle, and cools the electronic components mounted in the car stereo and car navigation. This is an embodiment in the case where excess heat of the electronic component is sent out into the vehicle interior. Moreover, in each embodiment described below, the same or corresponding parts as in FIG. 1 will be described using the same reference numerals.

(First embodiment)
With reference to FIGS. 2-6, the air conditioner of the electronic device in 1st Embodiment of this application is demonstrated.

  2 to 4 are side views showing the car stereo equipped with the air conditioner in the first embodiment of the present application, FIG. 5 is a block diagram showing the air conditioning circuit in the first embodiment of the present application, and FIG. 6 is a block diagram of the controller of FIG. It is a flowchart which shows operation | movement.

  2 shows a case where heat is radiated into the instrument panel of the vehicle, FIG. 3 shows a case where heat is radiated into the vehicle interior, and FIG. 4 shows a case where the inside of the main body case is cooled by cool air inside the vehicle compartment.

  As shown in FIGS. 2 to 4, a car stereo main body case 1 </ b> A that is an electronic device is attached so that a front panel 2 thereof is substantially flush with an instrument panel 3 in a vehicle interior. The front panel 2 is formed with a plurality of slits (not shown) through which air can flow between the main body case 1A and the vehicle interior. The main body case 1A and the front panel 2 constitute a housing of the present application. Although not shown, a structure such as a DVD mechanical unit, a tuner unit, and a plurality of substrate units on which electronic components such as IC and LSI are mounted are mounted inside the main body case 1A.

  As shown in FIG. 1, the back side (one side of the housing) inside the main body case 1A is a first air blowing member using a substrate, a connector attached thereto, and an axial fan, as in FIG. Structures such as the air cooling fan 10 and a cable attachment connector for drawing out a cable for attachment to the vehicle-side power harness are arranged.

  By the way, in this embodiment, as shown in FIGS. 2-4, it is the 2nd ventilation member which is the front side inside the main body case 1A (other side of a housing | casing), Comprising: An intake / exhaust fan 12 is disposed. The intake / exhaust fan 12 is a fan that can be rotationally driven in the forward direction and the reverse direction. Although not shown, an air conditioner for air conditioning is installed in the vehicle interior.

  Therefore, in the present embodiment, as shown in FIG. 2, the air cooling fan 10 is rotationally driven, so that excess heat generated in the main body case 1 </ b> A can be released into the instrument panel 3. Further, during heating of the air conditioner, by rotating the intake / exhaust fan 12 in the reverse direction as shown in FIG. 3, excess heat generated in the main body case 1A is sent into the vehicle compartment, By effectively using heat, the load on the air conditioner can be reduced. In particular, when the vehicle interior is desired to be warmed up early in winter or the like, the intake / exhaust fan 12 is driven to rotate in the reverse direction, and the heat in the main body case 1A is controlled to be sent out to the vehicle interior to promote the heating effect. Is possible.

  Further, at the time of cooling the air conditioner, as shown in FIG. 4, the air cooling fan 10 is rotationally driven, and the intake / exhaust fan 12 is rotationally driven in the forward direction, whereby cooling introduced from the vehicle interior outside the main body case 1A. By forcibly sending the air to the electronic component whose temperature has increased and releasing it into the instrument panel 3, the temperature inside the main body case 1A can be lowered and the electronic component can be cooled.

  In addition, since the air conditioner is off (stopped) and the environmental temperature (depending on season, region, and altitude) relative to the vehicle is low, the temperature inside the vehicle compartment is low and the temperature inside the main body case 1A is high. When it is desired to lower the temperature in 1A, the cooling air introduced from the vehicle interior outside the main body case 1A is turned into an electronic component whose temperature has increased by rotating the intake / exhaust fan 12 in the forward direction in the same manner as described above. By forcibly feeding and discharging into the instrument panel 3, the temperature inside the main body case 1A can be lowered, and the electronic component can be cooled.

  Therefore, according to the air conditioner of the present embodiment, the intake / exhaust fan 12 that is rotatable in the forward direction and the reverse direction is disposed on the vehicle interior side of the main body case 1A. By rotating and driving 12 in the reverse direction, the load on the air conditioner can be reduced by effectively using the heat in the main body case 1A. As a result, it is possible to reduce the load on the environment.

  Further, when the air conditioner is cooled, the air cooling fan 10 is rotationally driven and the intake / exhaust fan 12 is rotationally driven in the forward direction, whereby the cooling air is forcibly sent to the electronic component whose temperature has been increased. The temperature in the case 1A can be lowered, the cooling effect of the electronic component can be increased, and the operation of the electronic component can always be stabilized.

  Next, the air conditioning circuit in this embodiment is demonstrated based on FIG.

  As shown in FIG. 5, an air conditioner 14 that performs cooling and heating is installed in the passenger compartment (cabin) 13 as described above. The temperature sensor 16 as the second temperature sensor is attached to the compartment 13 side of the instrument panel 3, for example, and detects the temperature inside the compartment 13 outside the main body case 1A. Further, the temperature sensor 17 as the first temperature sensor is arranged in a temperature rising region which is a target area in the main body case 1A, and detects, for example, an ambient temperature in the vicinity of the pickup as the temperature rising region. For these temperature sensors 16, 17, for example, a small chip type thermistor, a platinum thin film temperature sensor, or the like is used. The temperature sensor 16 is not limited to the instrument panel 3 and may be attached to any location as long as it is inside the vehicle compartment 13.

  The controller 18 has a function as a control means, takes in a temperature detection signal detected by the temperature sensors 16 and 17, and performs on / off control of the air cooling fans 10 and 12. The controller 18 preferably uses an 8-bit microcomputer with a built-in A / D converter function. The controller 18 is not limited to the on / off control of the air cooling fans 10 and 12, and may adjust the fan air volume by voltage control. In this case, control is performed such as switching the voltage value to a plurality of stages and changing the rotational speed of the fan in stages. Further, although the controller 18 can be relatively freely arranged in the empty space of the main body case 1A, a controller for a car stereo control system that is installed in advance may be used without providing a new one in this way. it can.

  Next, the air conditioning method in this embodiment is demonstrated based on the flowchart of FIG. Note that the flowchart shown in FIG. 6 starts when the air conditioner of the present embodiment is turned on and ends when the air conditioner is turned off. Further, in the flowchart shown in FIG. 6, the target area (temperature rise region) temperature in the main body case 1A is Ta, the temperature in the passenger compartment (cabin) 13 is Tc, and the set temperature of the air conditioner (AC) 14 is Ts. Yes.

  First, in step S1, the controller 18 determines whether the setting of the air conditioner (AC) 14 is on. When the setting of the air conditioner 14 is on (step S1; Yes), the process proceeds to step S2, and a signal of the set temperature Ts of the air conditioner 14 is taken into the controller 18 at step S2.

  On the other hand, when the setting of the air conditioner 14 is off (step S1; No), the process proceeds to step S3, and the signal of the temperature Tc in the passenger compartment (cabin) 13 is taken into the controller 18 in step S3.

  In step S4, it is determined whether the temperature Tc in the passenger compartment 13 is less than 5 ° C. When the temperature Tc in the passenger compartment 13 is 5 ° C. or higher (step S4; No), the process proceeds to a standby process during a temperature sampling time in step S15 described later. When the temperature Tc in the passenger compartment 13 is less than 5 ° C. (step S4; Yes), the process proceeds to step S6 described later.

  Here, the process of step S1, step S3, step S4, and step S6 is a process for heating the interior of the passenger compartment 13 when the air conditioner 14 is off and the temperature Tc in the passenger compartment 13 is less than 5 ° C. It is. This value of less than 5 ° C. is an example of a temperature at which the air conditioner 14 is off and heating is required in the passenger compartment 13, and if it is a value that requires heating, it is set to another temperature. May be.

  Furthermore, in step S5, the controller 18 subtracts the temperature Tc in the passenger compartment 13 from the set temperature Ts of the air conditioner 14, and determines whether the value is positive (+). That is, the temperature Tc in the passenger compartment 13 is lower than the set temperature Ts of the air conditioner 14 (step S5; Yes), or the temperature Tc in the passenger compartment 13 is higher than the set temperature Ts of the air conditioner 14 (step S4; No) is determined. Specifically, it is determined whether the interior of the passenger compartment 13 is heated (step S5; Yes) or is cooled (step S4; No).

  When the interior of the passenger compartment 13 is to be heated (step S5; Yes), the process proceeds to step S6, and the temperature Ta of the target area (temperature increase region) in the main body case 1A is taken into the controller 18 in step S6. The processing from step S6 to step S11 described below is based on the assumption that the passenger compartment 13 is heated.

  Next, in step S <b> 7, it is determined whether the target area (temperature rise region) temperature Ta is lower than the temperature Tc in the passenger compartment (cabin) 13. When the target area temperature Ta is lower than the temperature Tc in the passenger compartment 13 (step S7; Yes), the process proceeds to step S8. In step S8, the controller 18 performs control so that both the air cooling fans 10 and 12 are turned off. In this case, the target area temperature Ta is an appropriate temperature, and there is no need to cool the electronic component.

  On the other hand, when the target area temperature Ta is equal to or higher than the temperature Tc in the passenger compartment 13 (step S7; No), the process proceeds to step S9. In step S9, the controller 18 determines whether the temperature Ta of the target area (temperature rise region) is equal to or higher than the temperature Tc in the passenger compartment 13 and equal to or lower than 70 ° C. This value of 70 ° C. or less depends on the design specifications of the electronic component. For example, if the temperature Tc in the passenger compartment 13 is 18 ° C., 18 ° C. ≦ Ta ≦ 70 ° C., and it is determined whether or not the target area (temperature rise region) temperature Ta is in the range of 18 ° C. to 70 ° C. become.

  When the target area (temperature rise region) temperature Ta is in the range of the temperature Tc (for example, 18 ° C.) to 70 ° C. in the passenger compartment 13 (step S9; Yes), the process proceeds to step S10. In this step S10, the controller 18 controls the intake / exhaust fan 12 to rotate in the reverse direction to generate excess heat generated in the body case 1A within the range of 18 ° C. to 70 ° C. The air is sent to the air to promote the heating effect. At the same time, the controller 18 controls the air cooling fan 10 to be turned off or exhausted. When exhausting, the air cooling fan 10 is rotationally driven as shown in FIG. 2, and excess heat generated in the main body case 1 </ b> A is released into the instrument panel 3.

  On the other hand, when the target area (temperature rise region) temperature Ta is not within the range of the temperature Tc (for example, 18 ° C.) to 70 ° C. in the passenger compartment 13 (step S9; No), that is, the target area (temperature rise region) temperature Ta is If it exceeds 70 ° C., the process proceeds to step S11. In step S11, the controller 18 controls the intake / exhaust fan 12 to rotate in the forward direction, and controls the air cooling fan 10 to rotate.

  Therefore, when the intake / exhaust fan 12 is driven to rotate in the forward direction, as shown in FIG. 3, air from the inside of the passenger compartment 13 outside the main body case 1A is introduced, and this air is forcibly sent to the electronic component whose temperature has risen. When the air cooling fan 10 is driven to rotate, the air whose temperature has increased in the main body case 1A is discharged into the instrument panel 3, thereby lowering the temperature in the main body case 1A and cooling the main body case 1A.

  In step S5, when the interior of the passenger compartment 13 is cooled (step S5; No), the process proceeds to step S12. In step S12, the controller 18 determines whether or not the temperature Ta of the target area (temperature rise region) is less than 70 ° C. Here, from the process of step S12 to the process of step S14 described below, it is assumed that the passenger compartment 13 is being cooled.

  When the temperature Ta of the target area (temperature rise region) is 70 ° C. or lower (step S12; Yes), the process proceeds to step S13. In this step S13, it is considered that the temperature Ta of the target area (temperature rise region) is within the set temperature, and the controller 18 controls the intake / exhaust fan 12 to be turned off and also turns off the air cooling fan 10. Or control to exhaust. In the case of this exhaust, the air cooling fan 10 is rotationally driven to release the air whose temperature has increased in the main body case 1 </ b> A into the instrument panel 3.

  On the other hand, when the temperature Ta of the target area (temperature rise region) exceeds 70 ° C. in step S12 (step S12; No), the process proceeds to step S14. In step S14, since the temperature Ta of the target area (temperature rise region) exceeds the set temperature, the intake / exhaust fan 12 is driven to rotate in the forward direction, and the vehicle outside the main body case 1A as shown in FIG. Cooling air from the inside of the chamber 13 is introduced and forcibly sent to the electronic component whose temperature has risen, and the air cooling fan 10 is rotationally driven to release the temperature-increased air in the main body case 1A into the instrument panel 3. Thus, the inside of the main body case 1A is cooled, and the temperature of the electronic component whose temperature has increased is decreased.

  When the processes in steps S4, S8, S10, S11, S13, and S14 are completed, the process proceeds to step S15. In step S15, a standby state is set during the sampling time. That is, in this step S15, the temperature Ta of the target area (temperature rise region) is monitored at a constant period, and the standby state is set for the set time of the controller 18.

  Next, in step S16, it is determined whether or not the temperature Ta of the target area (temperature rise region) exceeds the limit. Specifically, it is determined whether the temperature Ta of the target area is higher than 85 ° C. or lower than −40 ° C. These set values depend on the specifications of electronic components and the like arranged in the temperature rise region.

  If the temperature Ta of the target area does not exceed the limit (step S16; No), the process returns to step S1 and the above process is executed again.

  When the temperature Ta of the target area exceeds the limit (step S16; Yes), the process proceeds to step S17. In step S17, since the operating temperature range of the electronic component is exceeded, an emergency process such as issuing a warning with a buzzer, a lamp, etc., and turning off the power is performed, and then the entire process is terminated.

  Note that a program corresponding to the flowchart shown in FIG. 6 is recorded on an information recording medium such as a hard disk (which may be installed in the electronic apparatus of the present embodiment), or the program is stored on a network such as the Internet. It is possible to cause the microcomputer to function as the controller 18 according to the present embodiment by reading out and executing these using a general-purpose microcomputer.

  As described above, according to the present embodiment, the intake / exhaust fan 12 is arranged on the vehicle interior side of the main body case 1A, and the intake / exhaust fan 12 can be rotated in the forward direction and the reverse direction. During heating, the load on the air conditioner 14 can be reduced by effectively using the heat in the main body case 1A by rotationally driving the intake / exhaust fan 12 in the reverse direction. As a result, it is possible to reduce the load on the environment.

  Further, when the air conditioner 14 is cooled, the air cooling fan 10 is rotationally driven and the intake / exhaust fan 12 is rotationally driven in the forward direction, whereby the cooling air is forcibly sent to the electronic component whose temperature has been increased. The temperature in the case 1A can be lowered and the electronic component can be cooled. As a result, the operation of the electronic component mounted in the main body case 1A can be stabilized.

  Furthermore, according to this embodiment, since the intake / exhaust fan 12 can be rotated in the forward direction and the reverse direction, both the fan that can rotate in the forward direction and the fan that can rotate in the reverse direction can be installed. The structure can be simplified.

  In the present embodiment, if one end of the duct is connected to the intake / exhaust fan 12 and the other end of the duct is arranged below the seat in the passenger compartment, the intake / exhaust fan 12 is moved in the opposite direction. By rotating and driving, excess heat in the main body case 1A can be guided to the feet of the passenger, and the heating effect can be further enhanced.

(Second Embodiment)
FIG. 7 is a side view showing a car navigation system equipped with an air conditioner according to the second embodiment of the present application. In addition, the same code | symbol is attached | subjected to the part which is the same as that of the said 1st Embodiment, or respond | corresponds, and only a different structure and effect | action from the said 1st Embodiment are demonstrated.

  This embodiment has shown the example which applied the air conditioner of this application to the car navigation. In other words, the present embodiment is applied to an open / close-type in-vehicle electrical apparatus that cannot form a slit in the front panel.

  As shown in FIG. 7, an open / close monitor 20 as an open / close panel is attached to the main body case 1 </ b> B of the car navigation system so as to be openable / closable so as to be substantially flush with the instrument panel 3. The main body case 1B and the open / close monitor 20 constitute a housing of the present application. In addition, various structures such as electronic components are mounted in the main body case 1B as in the first embodiment.

  The open / close monitor 20 is connected to the drawer portion 21 via a connecting shaft 22 so as to be tiltable. In other words, the opening / closing monitor 20 is configured to tilt (tilt) when the drawer portion 21 protrudes toward the vehicle compartment 13 by rotating the opening / closing monitor 20 about the connecting shaft 22. Therefore, the open / close monitor 20 can circulate air between the main body case 1B and the interior of the passenger compartment 13 through a gap with the main body case 1B by being tilted and opened.

  Next, the operation and effect of this embodiment will be described.

  When the air conditioner 14 is heated, the open / close monitor 20 is tilted, and the intake / exhaust fan 12 is rotated in the reverse direction to dissipate the heat in the main body case 1B into the vehicle compartment 13 through the gap with the main body case 1B. Thus, the interior of the passenger compartment 13 can be warmed. In this case, the temperature in the main body case 1B, that is, the target area temperature Ta needs to exceed the temperature Tc in the passenger compartment 13 as described above.

  When it is detected that the temperature sensor 17 installed in the main body case 1B exceeds 70 ° C., for example, the open / close monitor 20 is tilted to rotate the intake / exhaust fan 12 in the forward direction. The cooling air in the passenger compartment 13 can be taken into the main body case 1B through the gap and the temperature in the main body case 1B can be lowered.

  As described above, according to the present embodiment, even in an open / close-type in-vehicle electrical device that cannot form a slit on the front surface, the open / close monitor 20 is tilted, and the heat in the main body case 1B is transferred to the open / close monitor 20 and the main body case 1B. By radiating heat into the vehicle compartment 13 through the gap, the heat in the main body case 1B can be used effectively, and the load on the air conditioner 14 can be reduced.

  Further, the opening / closing monitor 20 is tilted, and the cooling air in the passenger compartment 13 is taken into the main body case 1B, thereby lowering the temperature in the main body case 1B and stabilizing the operation of the electronic components mounted in the main body case 1B. It can be made. Since other configurations and effects in the present embodiment are the same as those in the first embodiment, description thereof will be omitted.

  The present application is not limited to the above embodiments, and various modifications can be made. For example, in each of the above embodiments, the present application is described as an example of an electronic device applied to a car stereo or a car navigation system.
