## Abstract

A conductor member with cooling structure includes a conductor member formed of a conductive metal in a strip shape, wherein one end side is connected to a component terminal of an electrical/electronic member, and the other end side is connected to an electrical connection target; a refrigerant case formed of an insulative resin to accommodate refrigerant, wherein a pair of refrigerant inlet/outlet ports are provided in the refrigerant case; and a heat transmission member with a first portion and a second portion that enters the refrigerant case to be connected to the refrigerant case in a state of being in contact with the refrigerant so as to connect the conductor member and the refrigerant case with each other, while receive heat generated in the conductor member by the first portion and transmit the heat from the second portion to the refrigerant flowing in the refrigerant case.

## Claims

### Claim 1

A conductor member with cooling structure, comprising:
a conductor member formed of a conductive metal in a strip shape, wherein one end side is connected to a component terminal of a predetermined electrical/electronic member, and the other end side is connected to an electrical connection target of the electrical/electronic member to be energized;
a refrigerant case formed of an insulative resin to accommodate refrigerant, wherein a pair of refrigerant inlet/outlet ports for the refrigerant to enter in and exit out thereof are provided in the refrigerant case; and
a heat transmission member with a first portion connected to the conductor member and a second portion that enters the inside of the refrigerant case to be connected to the refrigerant case in a state of being in contact with the refrigerant so as to connect the conductor member and the refrigerant case with each other, while receive heat generated in the conductor member by the first portion and transmit the heat from the second portion to the refrigerant flowing in the refrigerant case.

### Claim 2 (depends on 1)

The conductor member with cooling structure according to claim 1,
wherein in the conductor member, the one end side is connected to the component terminal by a screw fastening, and
in the heat transmission member, the first portion is fastened together with the one end side of the conductor member to be connected to the component terminal by the screw fastening.

### Claim 3 (depends on 1)

The conductor member with cooling structure according to claim 1, wherein in the refrigerant case, a component inlet port into which the second portion of the heat transmission member enters is formed, and the component inlet port is sealed by a predetermined sealing member in a state in which the second portion has entered the component inlet port.

### Claim 4 (depends on 1)

The conductor member with cooling structure according to claim 1, wherein the heat transmission member is formed in a strip shape, the first portion is superimposed on one of a front surface and a back surface of the conductor member, and the heat transmission member extends from a side edge in the conductor member in an intersecting direction with respect to the side edge such that the second portion enters the inside of the refrigerant case.

### Claim 5 (depends on 1)

The conductor member with cooling structure according to claim 1,
wherein the refrigerant is a fluid having conductivity,
the heat transmission member is formed of a conductive metal, and
at least one location between a connection location of the conductor member and the heat transmission member and a contact location with the refrigerant in the heat transmission member is applied with an insulation processing such that the conductor member and the refrigerant are electrically isolated from each other.

### Claim 6 (depends on 1)

The conductor member with cooling structure according to claim 1,
wherein the component terminals are provided in a pair in the electrical/electronic member,
the conductor members are provided in a pair such that the pair of conductor members are connected to the pair of component terminals by one-to-one correspondence and each thereof extends in an arrangement direction of the component terminals, and
the heat transmission members are provided in a pair such that the first portion of each of the pair of heat transmission members is connected to each of the pair of conductor members, and
the second portion of each of the pair of heat transmission members enters the inside of the refrigerant case to come into contact with the refrigerant.

### Claim 7 (depends on 6)

The conductor member with cooling structure according to claim 6.
wherein the pair of heat transmission members extend from the side edge at the same side between the pair of conductor members to intersect the arrangement direction, and
the second portion of each of the pair of heat transmission members enters the refrigerant case in a state of lining up in the arrangement direction, and the pair of refrigerant inlet/outlet ports are arranged such that the refrigerant flows along the arrangement direction.
