Abstract
A cooling structure of a rotating electric machine includes: a first common flow path member having electrical conductivity; a second common flow path member having electrical conductivity; and a plurality of connecting flow path members which connect the first common flow path member and the second common flow path member, which are inserted into a stator provided in the rotating electric machine, and each of which at least partially has electrical conductivity. Each of the plurality of connecting flow path members includes an insulating portion.
Claims9
A cooling structure of a rotating electric machine, the cooling structure comprising:
- a first common flow path member which has electrical conductivity and through which a coolant flows;
- a second common flow path member which has electrical conductivity and through which the coolant flows;
- and
- a plurality of connecting flow path members configured to connect the first common flow path member and the second common flow path member,
- wherein each of the plurality of connecting flow path members includes:
- a first pipe having electrical conductivity, inserted into a stator, and connected to the first common flow path member;
- a second pipe having electrical conductivity, inserted into the stator, and connected to the second common flow path member;
- and a connecting pipe configured to connect the first pipe and the second pipe, the connecting pipe including an insulating portion configured to prevent flow of electric current between the first pipe and the second pipe.
