The common-mode filter circuit includes: a ring-shaped common-mode transformer core with the secondary winding inserted inside; a primary winding wound around the common-mode transformer core in a manner that passes through the inside and outside of the common-mode transformer core; and a heat sink with the secondary winding inserted inside and engaged with the common-mode transformer core in a manner that the ends are mated together to exchange heat with the common-mode transformer core, wherein a notch through which the primary winding passes between the inside and outside of the common-mode transformer core is formed in the heat sink or the common-mode transformer core.

The laser device of the present application includes a vacuum container including a wall portion; a laser medium disposed in the vacuum container; a cooler disposed outside the vacuum container; and a heat transfer conductor which penetrates the wall portion in a prescribed direction and is connected to the laser medium and the cooler.

The invention provides a battery cooling device capable of appropriately cooling a battery pack. A battery cooling device is provided with: a blower for cooling a battery pack; a plurality of first sensors for detecting the temperature of each of the corresponding battery cells; a second sensor that detects an intake air temperature of the battery pack by the blower; and a controller that specifies the battery cell having the highest temperature among the plurality of battery cells as a first battery cell on the basis of the temperatures detected by the plurality of first sensors, and that specifies the battery cell having the highest temperature among the plurality of battery cells as a second battery cell at the temperature of the first battery cell detected by the first sensor for the first battery cell and the intake air temperature detected by the second sensor for the second battery cell. The number of rotations of the blower at which the cooling performance of the first battery cell is maximized is determined from the plurality of candidates, and the blower is controlled to rotate at the determined number of rotations.
