A connection member for coolant passages is provided. The connection member includes: a first end portion configured to be connected to the first opening via a shaft seal member; a second end portion configured to be connected to the second opening via a face seal member; a communication portion providing communication between the first end portion and the second end portion; a first fastening portion provided at a position in one direction such that a distance between the first fastening portion and the second end portion is larger than a distance between the first fastening portion and the first end portion; and a second fastening portion provided around the second end portion, and configured to be fastened to the case.

Connection member for coolant passages and cooler system

A coolant passage connection structure includes: a first coolant passage attached to a case which houses a cooler and has a second opening, and extending from the cooler; a second coolant passage that communicates with the second opening; a first connection member connected to the first coolant passage, and having a first opening; a first face seal member; and a second connection member connected to the first opening and the second opening via the first face seal member. The second opening is provided in the case so as to be positioned below the first connection member in a vertical direction. The first connection member is positioned above the first face seal member in the vertical direction and includes a tapered portion that includes an inclined surface inclined further away from a surface of the case toward a lower side in the vertical direction.

Coolant passage connection structure and cooler system

A connecting structure includes a housing, a cooler, an inner refrigerant pipe, an outer refrigerant pipe, and a joint pipe. The joint pipe is attached to a through hole of the housing. The inner refrigerant pipe is fitted to the joint pipe from a housing inner side. The outer refrigerant pipe is fitted to the joint pipe from a housing outer side. A tip of the inner refrigerant pipe and a tip of the outer refrigerant pipe define a gap inside the joint pipe. An end surface of a flange or a rib of the outer refrigerant pipe in a refrigerant-pipe axis direction abuts with an end surface of a flange or a rib of the joint pipe in the refrigerant-pipe axis direction.

Connecting structure for refrigerant pipe and inverter including connecting structure

Two opening through which a refrigerant runs are connected by a first connecting pipe and a second connecting pipe. One end of the first connecting pipe is connected to a first opening by a planar seal. Another end of the first connecting pipe is connected to one end of a second connecting pipe by a shaft seal. Another end of the second connecting pipe is connected to a second opening by a planar seal. An axial direction of a shaft seal is perpendicular to a plane that includes the first opening.
