Abstract
A DC/DC converter includes a metal case, a power converter accommodated in the case, a substrate, and a temperature sensor mounted on a surface of the substrate. The case includes a bottom wall, a side wall extending from the bottom wall, a boss, and a coupling portion. The coupling portion couples the side wall to the boss. The coupling portion extends from the bottom wall along an axis of the boss and along a surface of the side wall. The temperature sensor is arranged to face the coupling portion.
Claims5
An electronic device, comprising:
- a case that is cooled by a cooling medium;
- a substrate mounted on the case, the substrate including a land pattern that is in contact with the case;
- and
- a temperature sensor mounted on a surface of the substrate, the temperature sensor measuring a temperature of the case, wherein
- the case includes:
- a bottom wall;
- a side wall on the bottom wall;
- a boss on the bottom wall, the boss supporting the substrate;
- and
- a coupling portion that couples the side wall to the boss and extends from the bottom wall toward the substrate,
- the boss includes a support surface that supports the substrate, and
- the coupling portion includes an opposing surface that faces the temperature sensor at a position that is lower than a height from the bottom wall to the support surface.
