The inverter converts a direct current from a secondary battery as a high voltage source into an alternating current for driving the electric motor and supplies the alternating current to the electric motor. An electromagnetic noise may be generated from the inverter and a noise may be generated from electronic components constituting the inverter, and the inverter becomes an electromagnetic noise source and a noise source. Furthermore, since the built-in switching element generates heat when operated, the inverter also serves as a heat source.

  As shown in FIG. 2, a plurality of slits 31 to 33 are formed in layers along the side wall 12 at intervals in the thickness direction on the front and rear side walls 12 to 15 constituting the case base 16. In the housing case 10 shown in FIG. 2, three slits, that is, a slit 31 on the outer side in the width direction of the side wall, a slit 32 in the middle part in the width direction, and a slit 33 on the inner side in the width direction are formed on each of the side walls 12 to 15. The three slits 31 to 33 are separated in the thickness direction of the side wall.

  As shown in FIGS. 3 to 6, each of the slits 31 to 33 is partitioned by reinforcing ribs 31 a to 33 a that extend in the vertical direction at predetermined intervals in the length direction of the side walls 12 to 15. . 4 shows the reinforcing ribs 31a and 33a of the slit 31 and the slit 33, and FIG. 5 shows the reinforcing rib 32a of the slit 32. However, the slits 31 to 33 may be integrally formed without providing the reinforcing ribs 31a to 33a.

  An electromagnetic shield member 41 as a blocking member that blocks electromagnetic noise generated from the electronic device 19 is attached to the outer slits 31 provided on the four side walls 12 to 15. Further, a sound insulating member 42 as a blocking member for blocking the operation sound generated from the electronic device 19 is attached to the slits 32 at the intermediate portions provided in the respective side walls 12 to 15. As the electromagnetic shield member 41, for example, ferrite containing iron oxide as a main component is used. As the sound insulating member 42, a sound absorbing material made of a fiber material such as rock wool or glass wool is used. When the electromagnetic shield member 41 is attached to the slit 31, electromagnetic noise as a transmission generated from the electronic device 19 and transmitted to the outside of the housing case 10 is blocked by the electromagnetic shield member 41. Furthermore, when the sound insulation member 42 is attached to the slit 32, the sound insulation member 42 blocks the operating sound that is generated from the electronic device 19 and permeates to the outside of the housing case 10.

  A temperature adjusting medium 43 for adjusting the temperature of the storage chamber 20 is circulated and supplied to the inner slits 33 provided in the respective side walls 12 to 15. In order to circulate the temperature control medium 43 in the slits 33 formed in the four side walls 12 to 15, the upper and lower ends of the reinforcing ribs 33a for partitioning the slits 33 are notched as shown in FIG. 35 is provided. Each slit 33 is continuous through the notch 35. When the storage chamber 20 is cooled by the temperature control medium 43, the heat generated from the electronic device 19 can be released to the outside. On the other hand, when the storage chamber 20 is heated by the temperature control medium 43, the electronic device 19 can be preheated at the initial start of the electronic device 19, and the electronic device 19 can exhibit desired efficiency or performance.

  As shown in FIGS. 4 to 6, a sealing material 36 is attached in a layered manner to the inner surface of the top wall 17, and when the top wall 17 comes into contact with the openings of the side walls 12 to 15, the slit 33 opens. The part is closed, and the temperature control medium 43 in the slit 33 is prevented from leaking outside.

  FIG. 7 is a cross-sectional view showing a state in which a blocking member is inserted in the front and rear side walls 12 and 13. Since the slits 31 to 33 are opened on the top wall 17 side of the side walls 12 to 15, in order to attach the plate-like electromagnetic shield member 41 to the slit 31 provided in the case base 16, the opening of the slit 31 is used. The electromagnetic shielding member 41 is inserted from the part side. Similarly, in order to attach the plate-like sound insulation member 42 to the slit 32, the sound insulation member 42 is inserted from the opening of the slit 32. Similarly, when mounting the blocking member on the left and right side walls 14 and 15, the electromagnetic shield member 41 is inserted into the slit 31 from the opening side, and the sound insulating member 42 is inserted from the opening side. Since the thickness dimensions of the slits 31 and 32 are set to be the same, the electromagnetic shield member 41 may be inserted into the central slit 32 and the sound insulating member 42 may be inserted into the outer slit 31.

  FIG. 8 is a schematic view showing a temperature control medium supply pipe into the slit 33. A supply side joint 44 and a discharge side joint 45 are attached to the case base 16 so as to communicate with the slit 33. In FIG. 8, the discharge-side joint 45 is shown enlarged, and the inner end of the discharge-side joint 45 communicates with the slit 33. Similarly, the supply-side joint 44 has an inner end communicating with the slit 33.

  The supply side joint 44 is connected to the discharge port of the medium tank 47 by a pipe 46, and the discharge side joint 45 is connected to the inlet of the medium tank 47 by a pipe 48. The medium tank 47 is filled with a temperature control medium 43 made of a liquid, and the pipe 46 is provided with a pump P. The pump P is driven by a motor (not shown), and the temperature control medium 43 in the medium tank 47 is circulated and supplied into the slit 33 by driving the pump P. Although the temperature control medium 43 is circulated and supplied to the inner slit 33, the temperature control medium 43 may be circulated to the outer or intermediate slits 31 and 32. However, since the inner slit 33 is located closest to the storage chamber 20, the temperature of the storage chamber 20 can be adjusted efficiently, and it is preferable to circulate the temperature control medium 43 through the inner slit 33. .

  The medium tank 47 is provided with a heater 51 for heating the temperature control medium 43 and a cooler 52 for cooling. The heater 51 and the cooler 52 are each formed by a Peltier element. Each Peltier element has a p-type thermoelectric semiconductor and an n-type thermoelectric semiconductor connected by a copper electrode, and when a current is passed through the electrode, heat can be generated or absorbed at the junction. The heater 51 and the cooler 52 are formed using the Peltier element having such characteristics. When the electrode in contact with the temperature control medium 43 is heated, the heater 51 is formed. When the heat is absorbed, the cooler 52 is cooled. It becomes. A temperature sensor 53 for detecting the temperature is provided in the storage chamber 20. The detection signal of the temperature sensor 53 is sent to the controller 54, and the controller 54 controls the driving of the heater 51 and the cooler 52 based on the signal from the temperature sensor 53. Thereby, the temperature of the temperature control medium 43 is controlled, and the temperature of the storage chamber 20 is adjusted so that it may become a temperature range where the electronic device 19 operates efficiently.

  A Peltier element may be used as the cooler 52, and a heating wire may be used as the heater 51. Moreover, a heat exchanger is used as the heater 51 and the cooler 52, the engine coolant is circulated through the heat exchanger of the heater 51, and the refrigerant of the air conditioner is circulated through the heat exchanger of the cooler 52. You may do it.

  The inverter as the electronic device 19 generates electromagnetic noise and operation sound of electronic components, and generates heat when the operation time elapses. For this reason, the electromagnetic shield member 41 and the sound insulation member 42 are attached to the two slits 31 and 32 to prevent electromagnetic noise and operating sound generated from the inverter from being transmitted to the outside. Further, the temperature control medium 43 is circulated and supplied to the slit 33 to prevent the inverter from being overheated, and when the inverter temperature is lower than a predetermined temperature, the inverter 33 is used to improve the operating efficiency. Is preheated.

  Depending on the electronic device 19 accommodated in the accommodating chamber 20, there may be no case where an operating sound is generated. In this case, the electromagnetic shield member 41 can be attached to the slits 31 and 32 at the outer and central portions. Further, when the electronic device 19 that does not generate operating noise and does not generate heat during operation is accommodated in the accommodating chamber 20, the electromagnetic shielding member 41 is also provided in the slit 33 without supplying the temperature control medium 43 to the slit 33. Installed. As described above, when a plurality of slits are provided in layers on the side walls 12 to 15 constituting the housing case 10, different types of blocking members and the same type of diagnostic members are attached to the slits according to the characteristics of the electronic components. Can do.

  When a member such as the electromagnetic shield member 41 is inserted into the slit, the strength of the case base 16 can be increased without increasing the thickness of the side walls 12 to 15. Therefore, the strength of the housing case can be maintained even when the housing case has the same thickness as that of the side wall in the conventional housing case in which the side walls 12 to 15 are not provided with slits.

  FIG. 9 is a partially omitted cross-sectional view showing a modified example of the housing case of the electronic device. FIG. 9 shows a cross section of the same portion as FIG. 6 in the case base 16 constituting the housing case 10.

  In the housing case 10 shown in FIG. 9, four slits 31 to 34 are provided on the side walls 12 and 13 with a space in the thickness direction. The other side walls 14 and 15 are similarly provided with four slits. The electromagnetic shielding member 41 is inserted into the outer slit 31 and the sound insulating member 42 is inserted into the inner slit 32 of the side walls 12 to 15 of the housing case 10 of this form. The inner slit 33 is filled with a phase change heat storage material 55, and the temperature control medium 43 is circulated and supplied to the inner slit 34.

  The phase change heat storage material 55 has a function of storing heat by using heat of fusion or heat of solidification when absorbing or releasing heat when the state of the substance changes between solid and liquid. doing. Thereby, when the temperature of the storage chamber 20 becomes high, the heat is absorbed and the overheating of the storage chamber 20 is prevented. On the other hand, when the temperature of the storage chamber 20 becomes low, heat can be radiated to prevent the storage chamber 20 from being overcooled. As the phase change heat storage material 55, for example, a paraffin-based latent heat storage material or the like is used.

  In the case base 16 of the housing case 10 described above, the bottom wall 11 and the four side walls 12 to 15 are integrated, but the bottom wall 11 and the side walls 12 to 15 are used as separate members by abutting them. The case base 16 may be formed. Further, the bottom wall 11 and the top wall 17 may be formed with slits in layers, and the electromagnetic shield member 41 and the like may be attached to the respective slits.

  In the storage case 10 shown in FIG. 9, the thickness is different between the front side wall 12 and the rear side wall 13 of the storage case 10. When the storage case 10 is mounted on the vehicle V, the storage is performed such that the front side wall 12 of the storage case 10 faces the front side of the vehicle V and the rear side wall 13 of the storage case 10 faces the rear side of the vehicle V. Case 10 is attached to vehicle V.

  The thickness dimension L1 of the outer side, that is, the outermost slit 31 and the outer surface of the side wall 13 is larger than the thickness dimension L2 of the outermost layer slit 31 and the outer surface of the side wall 12. The thickness dimensions of the other side walls 14 and 15 are set in the same manner as the dimension L2. As described above, since the rear side wall 13 is set to be thick, even if another vehicle collides with the vehicle V, a portion to which a load is applied in the housing case 10 mounted on the rear side of the vehicle V. The strength of can be increased. Also in the case 10 having the above-described configuration, the thickness between the outermost layer slit on the rear side wall 14 and the outer surface of the side wall 13 is set to be larger than the same thickness on the other side walls. You may do it.

  FIG. 10 is a cross-sectional view illustrating a part of another modification of the electronic device housing case. The housing case 10 has a case base 16 in which a bottom wall 11 and side walls 12 to 15 are separate members, and slits are formed in the bottom wall 11 and the top wall 17 respectively.

  FIG. 10 shows the bottom wall 11, one side wall 14, and a part of the top wall 17. The side wall 14 is integrated with the other side walls 12, 13, and 15. A quadrilateral frame is formed by the four side walls, and the side walls 12 to 15, the bottom wall 11, and the top wall 17 are each formed by separate members. Flange portions 26 and 27 are provided on the outer peripheral portions of the bottom wall 11 and the top wall 17 so as to cover the outside of the frame body composed of four side walls. Like the side wall 14, the bottom wall 11 and the top wall 17 are formed with three slits 31 to 33 in a layered manner with an interval between them, and the outer slit 31 is fitted with an electromagnetic shield member 41, A sound insulating member 42 is attached to the slit 32. Further, the temperature control medium 43 is circulated and supplied to the inner slit 33.

  The slits 31 to 33 formed in the side wall 14 penetrate vertically in FIG. 10, and the other side walls are the same. The slits 31 and 32 formed in the bottom wall 11 and the top wall 17 are opened on one side surface of the bottom wall 11 and the top wall 17, and the electromagnetic shielding member 41 and the sound insulation member 42 are inserted from the opened side surface side. Is done. On the other hand, the opening of the slit 33 to which the temperature control medium 43 is supplied is closed by the closing member 56. Furthermore, a sheet-like sealing material 36 is attached to the inner surfaces of the bottom wall 11 and the top wall 17 to prevent the temperature control medium 43 from leaking outside. In the storage case 10 of this form, the entire storage chamber 20 is covered with the electromagnetic shield member 41 and the sound insulating member 42, and the transmission of electromagnetic noise to the outside and the transmission of operating sound are prevented. Further, the temperature of the storage chamber 20 is adjusted from six wall surfaces constituting the storage case 10.

  As described above, at least the side walls 12 to 15 in the housing case 10 for housing the electronic device 19 are formed by laminating a plurality of slits in layers and spaced apart from each other. Depending on the type of the electronic device 19, electromagnetic noise and operating sound generated from the electronic device 19 are prevented from being transmitted to the outside from the housing case 10, so that electromagnetic noise is generated in other electronic devices mounted on the vehicle. Leakage is prevented, and malfunction of other electronic devices can be prevented. Furthermore, the operating sound of the electronic device 19 is prevented from leaking into the vehicle interior, and the vehicle interior can be kept quiet. Further, if the temperature control medium 43 is circulated in the slit, the temperature of the storage chamber 20 can be maintained at a temperature at which the electronic device 19 operates efficiently, so that the electronic device 19 can be operated with optimum performance. it can.

  In addition, since a plurality of slits are formed in at least the side walls 12 to 15 and a blocking member such as the electromagnetic shield member 41 is inserted therein, the housing case 10 can be formed without increasing the thickness dimension of the side walls 12 to 15. It can be downsized. By providing slits in the bottom wall 11 and the top wall 17 in addition to the side walls 12 to 15 and mounting a blocking member such as the electromagnetic shield member 41 in the slit, the blocking effect of the permeate can be further enhanced. .

  FIG. 11 is a characteristic line comparing the thickness of the case body and the electromagnetic noise blocking effect when the electromagnetic shield member 41 is mounted in the slit 31 and when the electromagnetic shield member is not provided as a comparative example. FIG.

  In FIG. 11, the thickness dimension of the horizontal axis shows the thickness dimension of only the case main body when no electromagnetic shielding member is provided, and when the electromagnetic shielding member is provided, the case main body and the electromagnetic shielding member incorporated therein The total dimensions are shown. The vertical axis represents the electromagnetic noise blocking amount. As shown in FIG. 11, when the electromagnetic shield member 41 is attached to the side wall or the like constituting the case body, the transmission of electromagnetic noise from the electronic device 19 to the outside is reliably prevented without increasing the thickness of the case body 18. We were able to. The permeation preventing effect was the same for the transmission of the operating sound generated from the electronic equipment by mounting the sound insulation member on the slit.

  In addition, the weight of the housing case 10 can be significantly reduced as compared with the case where no slit is provided in the case main body 18, and the electromagnetic shield member is covered outside the case main body 18. Moreover, the manufacturing cost of the storage case 10 can also be reduced.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, the electronic device 19 is not limited to the inverter described above, and the present invention can be applied as a housing case for housing a secondary battery and other electronic devices.
