摘要： An open part that has an opening surface that is perpendicular to the horizontal direction is formed in a housing of a vehicle control device. An interior of the housing is divided into a first space including the open part and a second space by a partitioning member, a main surface thereof having a hole formed therein and opposing the opening surface. The semiconductor cooling unit is housed in the first space. The semiconductor cooling unit is detachably attached in a direction in which the opening surface and the partitioning member oppose each other. An engaging member arranged on the cover of the semiconductor cooling unit engages a guide arranged on the housing, and the guide supports weight of the semiconductor cooling unit. A heat sink is provided on a base plate and forms a vertically-directed flow passage.

摘要： This storage battery module includes battery cells, a first plate-shaped member, and a second plate-shaped member opposing the first plate-shaped member across an insulating member. The first plate-shaped member has conductors formed therein. The second plate-shaped member has formed therein a heat dispersion region opposing at least a portion of the conductors of the first plate-shaped member across the insulating member. Heat generated in the conductors of the first plate-shaped member is transferred to the heat dispersion region of the opposing second plate-shaped member, and the heat is dispersed inside the heat dispersion region.

摘要： A frame portion is a plate-like member to which a cooler is attached for cooling an electric circuit element configured to operate for power conversion that causes generation of heat. The capacitor is a structural member disposed in a direction perpendicular to the frame portion and including a capacitor element electrically connected to the electric circuit element. The capacitor includes a first support surface and a second support surface that are external surfaces facing in opposite directions from each other and parallel to the direction perpendicular to the frame portion. The first frame and the second frame each have an end portion fixed to a connection frame. The first frame includes a first attachment surface fixed to a first support surface. The second frame includes a second attachment surface fixed to a second support surface.

摘要： A cooling device includes a heat-receiving block, a heat conductor, and first heat pipes. The heat-receiving block has a first main surface to which a heating element is fixed. The heat conductor extends along the first main surface and is fixed to the heat-receiving block. The first heat pipes are arranged in a direction in which the heat conductor extends and are fixed to the heat-receiving block at positions farther from the first main surface than the heat conductor is.

摘要： A housing of a power conversion device is partitioned into sealed and open parts. A first housing containing a primary-side electronic component connected to a primary winding of a transformer has a first opening through which a first connection conductor is inserted, the first opening being blocked by an aperture surface included in a third housing containing the transformer and filled with an insulating member. A shortest distance between the first connection conductor and an edge of the first opening is greater than or equal to a first threshold. A second housing containing a secondary-side electronic component connected to a secondary winding of the transformer has a second opening through which a second connection conductor is inserted, and is blocked by the aperture surface. A shortest distance between the second connection conductor and an edge of the second opening is greater than or equal to a second threshold.

摘要： A power conversion device includes a filter capacitor to accumulate therein DC power, and an element unit including a semiconductor element module to perform a switching operation for converting the DC power accumulated in the filter capacitor into AC power. The filter capacitor and the element unit are disposed in the same casing. A heat-resistant capacitor having a higher heat resistance than the filter capacitor is connected to the element portion by using a connection conductor, and is also connected to a busbar different from the connection conductor. An electrical connection between the filter capacitor and the element unit is established through the busbar, the connection conductor, and the heat-resistant capacitor.
