Bus bar for power supply with coolant flow passages
First Claim
Patent Images
1. A bus bar for power supply comprising an outer conductor formed in a pipe shape, at least one inner conductor inserted in said outer conductor, and an insulation layer filling every space between opposite surfaces of adjacent conductors for electrically isolating said conductors from each other;
- said inner conductor being formed in a pipe shape smaller than said outer conductor and serving as a coolant flow passage;
wherein said outer conductor is made up of a pair of side plates and at least two partition members fixedly interposed between said side plates, said partition members being respectively situated at opposite ends of said side plates to define in cooperation therewith a hollow portion which is rectangular in cross-section, each partition member being formed in a pipe shape which has a rectangular cross-section to form a coolant flow passage.

Abstract
A bus bar for power supply is comprised of a pipe-shaped outer conductor and at least one inner conductor inserted therein. The inner conductor is also formed in a pipe shape and serves as a coolant flow passage. Insulation is interposed between the outer conductor and the inner conductor to electrically isolate them from each other.
