    Abstract: A power conversion apparatus is equipped with grommets each of which hermetically seals between one of a coolant inlet tube and a coolant outlet tube of a cooler. Each of the grommets has a sealing protrusion and is fit in a cut-out formed in an end of a side wall of a casing with the sealing protrusion pressed against an inner wall of the cut-out. The installation of each of the grommets is achieved by inserting the grommet through the cut-out in a direction from outside to inside the casing so that a portion of the grommet protrudes from the wall into the casing. The visual perception of such protrusion made by an assembly worker, therefore, enables the assembly worker to determine whether the grommet has been installed in place in the cut-out to establish a desired hermetical seal or not.

    Abstract translation: 电力转换装置配备有垫圈，每个垫圈密封在冷却剂的冷却剂入口管和冷却剂出口管中的一个之间。 每个垫圈具有密封突起，并且被配合在形成在壳体的侧壁的端部中的切口中，密封突起压靠在切口的内壁上。 每个垫圈的安装是通过将套管穿过切口从外部插入到壳体内部的方向来实现的，使得一部分索环从壁突出到壳体中。 因此，由组装工人进行的这种突起的视觉感知能够使装配工人能够确定护栏是否已经安装在切口中的适当位置以建立所需的密封。

    Abstract: An electric power converter includes a stacked semiconductor unit formed by stacking semiconductor modules and cooling tubes, and a case. The case has a rear wall portion, a front wall portion, and a pair of side wall portions. The rear wall portion has an opening hole formed in a shape that an outer profile of the cooler fits inside. The stacked semiconductor unit has a closing member joined to a rear-most cooling pipe that is disposed on a rear side to close the opening hole, a refrigerant introducing pipe extended rearward from the closing member, and a refrigerant discharging pipe extended rearward from the closing member. The refrigerant introducing pipe and the refrigerant discharging pipe, and the closing member are connected in close contact with each other, and the closing member and the case are in close contact by a seal section.

    Abstract: A power conversion device includes a semiconductor unit, a terminal unit, a capacitor unit, a control board, and a case. The semiconductor unit is arranged at a position facing a plate surface of the control board. The terminal unit and the capacitor unit are arranged side by side in a x direction along the plate surface of the control board on the opposite side of the control board with respect to the semiconductor unit. At least a part of the capacitor unit or the terminal unit is located outside a first end of the semiconductor unit in the x direction. A first recess in which a first electrical wiring is arranged is formed in a portion of the case facing the first end so as to be recessed inside the case.

    Abstract: A pressing member is used for pressing semiconductor modules and cooling pipes which are alternately disposed, and includes a plate and an elastic member. The plate includes a contact plate section that faces an end surface of the fixed unit in the fixed direction and contacts with the end surface of the fixed unit, and plate ribs standing in the fixed direction from an end portion of the contact plate section in a width direction of the contact plate section. The elastic member is disposed in a side of the plate opposite to a side of the plate where the fixed unit is disposed, the elastic member pressing the plate towards a fixed unit side in the fixed direction. The contact plate section has an inner plate surface including a concave surface formed at a portion apart from the plate ribs in a contact region.

    Abstract: A power conversion apparatus includes a semiconductor module that includes a main body containing at least one semiconductor element, power terminals projecting from the main body to be connected to a high-voltage DC power supply and high-voltage signal terminals projecting from the main body, and is configured to convert a DC power supplied from the high-voltage DC power supply to an AC power by switching operation of the semiconductor element. The power conversion apparatus further includes a low-voltage component connected to a low-voltage DC power supply and a control circuit board on which a control circuit for controlling the switching operation of the semiconductor element is formed. The control circuit board is connected with low-voltage signal terminals extending from the low-voltage component and the high-voltage signal terminals. The low-voltage and high-voltage signal terminals are solder-connected to the control circuit board.
