- the semiconductor element is placed on the substrate while preventing the temperature during operation of the semiconductor element constituting the electronic control device from unnecessarily rising with a unified guideline. Can be implemented.
- the semiconductor element is formed on the substrate so that the large heat generating terminals do not face each other. Therefore, it is possible to more reliably prevent the temperature during operation of the semiconductor elements constituting the electronic control device from being unnecessarily increased.
- the first small heat generating semiconductor element, the first large heat generating semiconductor element, and the second large heat generating semiconductor element constitute a modularized driver device.

- the terminal 38 is electrically connected to a driving relay 8 for driving a solenoid for adjusting the pressure of lubricating oil in the internal combustion engine of the vehicle.
- FIG. 3A is a top view showing a configuration in which each driver IC in the electronic control device according to the present embodiment is mounted on a substrate.
- FIG. 3B is a side view showing a configuration in which each driver IC in the electronic control device according to the present embodiment is mounted on a substrate, and corresponds to a view taken along arrow A in FIG. 3A.
- the x-axis, y-axis, and z-axis form a three-axis orthogonal coordinate system, and the direction of the z-axis is the vertical direction.
- each of the driver ICs 10, 20, and 30 typically has peripheral electrical components or the like not shown on a substrate SB that is a glass epoxy substrate on which printed wiring is arranged. Implemented while avoiding where appropriate.
- the electrical components 3 to 8 to be driven are connected to the electronic control unit 1, and the driver ICs 10, 20, and 30 are respectively operated for a predetermined time to measure the temperature of the sealing housing at a plurality of locations and take an average.
- the temperature of the sealing housing of the driver IC 10 is the lowest, the temperature of the sealing housing of the driver IC 20 is the highest, and the temperature of the sealing housing of the driver IC 30 is higher than that of the driver IC 10.
- the temperature was intermediate between those of the driver IC 20.
- the temperature of the terminal 14 of the driver IC 10 was the lowest.
- the temperature of the terminal 21 of the driver IC 20 is the highest, and the temperature of the terminal 14 of the driver IC 10, the terminal 25 of the driver IC 20, and the terminal 31 and the terminal 38 of the driver IC 30 are determined by the temperature of the terminal 14 of the driver IC 10. Although the temperature is high, the temperature is intermediate between them, which is lower than the temperature of the terminal 21 of the driver IC 20.
- Such a phenomenon has occurred because the terminal 14 of the driver IC 10 is electrically connected to the driving relay 5 for driving the light emitting diode of the indicator with a small load.
- the terminal 21 of the driver IC 20 is connected to a power supply relay 3 for supplying power to a starter having a large load. Since they are electrically connected, the power value consumed by the corresponding internal electric circuit is the largest and the amount of heat generation is relatively largest, while the remaining heat-generating terminals 18, 25, 31. , 38 are electrically connected to an intermediate load with respect to them, the power value consumed by the corresponding internal electric circuit takes a relatively intermediate value, and the amount of generated heat It believed to be due to taking a relatively intermediate values.
- the driver IC 10 having the internal electric circuit with the lowest power consumption and the internal electric circuit with the medium power consumption has the smallest amount of heat generated during operation, and the temperature of the sealed casing is the lowest, and the power consumption is the lowest.
- a driver IC 20 having a large internal electric circuit and an internal electric circuit with medium power consumption has the largest amount of heat generation, the highest temperature of the sealed casing, and an internal electric circuit with medium power consumption. Since the amount of heat generated during the operation of the two driver ICs 30 is intermediate, it can be concluded that the temperature of the sealed casing has reached an intermediate temperature.
- the driver IC 10 is called a small heat generating driver IC
- the driver ICs 20 and 30 are large in operation because the temperature of their sealed casing is higher than the temperature of the sealed casing of the driver IC 10. It can be called a heat-generating driver IC.
- the driver ICs 20 and 30 are arranged so as to sandwich the driver IC 10 on the substrate SB.
- the position of the driver IC 10 shown is moved upward or downward and placed at the position of the driver IC 10 ′ indicated by the two-dot chain line or the position of the driver IC 10 ′′, the position is compared with that at the position of the driver IC 10 indicated by the solid line.
- the temperature of the sealed housing of each of the driver ICs 20 and 30 rises, and when the position of the driver IC 10 is moved upward or downward toward the end of the substrate SB, the driver ICs 20 and 30 The temperature of each sealed casing increased further.
- This phenomenon occurs because the thermal radiation of one of the driver ICs 20, 30 that generates heat during operation propagates to the other more greatly in response to the movement of the position of the driver IC 10 relative to the driver ICs 20, 30. This is considered to be because the temperature of the sealed housing of each of the driver ICs 20 and 30 has increased.
- the heat radiation from the driver IC 20 toward the driver IC 30 is mainly emitted from the vertical walls 20A and 20B facing the driver IC 30 among the vertical side walls perpendicular to the upper surface of the substrate SB in the sealing housing of the driver IC 20. Since the vertical walls 30A and 30B facing the driver IC 20 among the vertical side walls perpendicular to the upper surface of the substrate SB in the sealing housing of the driver IC 30 are received, the radiation area of the heat radiation from the driver IC 20 toward the driver IC 30 is As shown in FIG. 3A, the region H is defined by the contour edges of the vertical walls 20A and 20B of the driver IC 20 and the contour edges of the vertical walls 30A and 30B of the driver IC 30. Further, a radiation region of heat radiation from the driver IC 30 toward the driver IC 20 is defined in the same manner, and can be evaluated as matching with the region H shown in FIG. 3A.

It is thought that the temperature increases.
- the driver ICs 20 and 30 receive the heat generated by each other as they are, so that the temperature of each sealed casing is the original temperature.

- the temperature of the sealed casing of the driver IC 10 during operation is lower than the temperature of the respective sealed casings of the driver ICs 20 and 30 during operation. Therefore, when the driver IC 10 is disposed in the heat radiation region H, the sealed housing mainly functions as an absorbing object that absorbs the heat generated by the driver ICs 20 and 30, and as a result, the driver ICs 20 and 30 It can be seen that the amount of heat received can decrease and the temperature of the sealed housing of each of the driver ICs 20 and 30 can decrease.
- the sealing housing of the driver IC 10 is between the sealing housings of the driver ICs 20 and 30 and substantially the entire heat radiation region H. Therefore, it is possible to absorb a larger amount of heat propagating through the driver IC 20, compared to the case where the driver IC 10 ′ and the position of the driver IC 10 ′′ indicated by a two-dot chain line are placed. It can be understood that the temperature of each of the 30 sealed casings is further lowered.
- the sealing housing of the driver IC 10 is arranged so as to block at least a part of the heat radiation area H, such as the position of the driver IC 10 ′ indicated by a two-dot chain line in 3A and the position of the driver IC 10 ′′,
- the temperature of the sealed housing of each of the driver ICs 20 and 30 can be lowered as compared with the case where no driver IC 10 is disposed in the heat radiation region H. Further, the temperature during the operation is low.
- the shape of the sealing housing of the relatively low heat-generating driver IC 10 is a rectangular parallelepiped in terms of the convenience of blocking the heat radiation region H reliably and efficiently. It can be said that Masui.
