好な状態となる。In FIG. 1, 1 is a metal outer case, 2 is a cover, 3 is a resin substrate, 4 is a control component, and 4 is a control component.
Is attached to the substrate 3, and is attached to the surface of the outer case located inside the cover 2 attached to the outer case 1. Further, as shown in FIG. 2, the outer case 1 is provided with a plurality of openings 5 along the inside of the contact surface A between the outer case 1 and the cover 2 so as to surround the control component 4. There is. By the opening 5, even when the outer case 1 located outside the cover 2 is exposed to sunlight, the heat applied is transferred to the inside of the cover 2 by heat transfer rather than heat transfer, so that heat is blocked. The temperature distribution of the outer case 1 located inside the cover 2 is as shown in FIG. Therefore, as shown in FIG. 3, the ambient temperature inside the cover 2 becomes lower when the opening 5 is provided, because the temperature of the outer case 1 is lower. At this time, when a ventilation port is provided for ventilation, the influence of heat generation of the device body is reduced, but the heat radiation loss is increased accordingly and the performance of the device is degraded. Further, in this example, since the substrate 3 is made of resin having a low thermal conductivity, it is possible to provide the opening 5 inside the substrate 3. However, if the substrate 3 is made of metal, the substrate 3
When the opening 5 is provided inside the substrate 2, heat is transferred to the substrate 3 through the outer case 1 and the atmosphere inside the cover 2 rises. In that case, the substrate located near the inside of the contact surface between the cover 2 and the outer case 1 is If the opening 5 is provided on the outer side of the outer case 3, heat transfer from the outer case 1 can be blocked. In addition,
By attaching a resin having a low thermal conductivity to the above-mentioned opening to prevent air from entering and exiting, heat conduction from the outer case 1 is reduced, and no air enters and exits, resulting in a good thermal condition.
