## Abstract

Methods and systems are provided for a compressor coolant chamber. In one example, a system comprising dividing the coolant chamber into two portions, a first portion adapted to couple to a second portion and shape a coolant chamber therebetween.

## Claims

### Claim 1

A system comprising:
a compressor comprising a cooling element divided into a first portion and a second portion, wherein the first portion is a solid continuous cap free of passages and the second portion comprises a coolant chamber comprising a plurality of fins,
wherein the first portion is a back plate first portion and the second portion is a back plate second portion, further comprising a compressor housing first portion and a compressor housing second portion, and wherein the cooling element is a first cooling element, the compressor further comprising a second cooling element, wherein the first cooling element corresponds to the back plate first and second portions and the second cooling element corresponds to the compressor housing first and second portions.

### Claim 2 (depends on 1)

The system of claim 1, wherein the first and second portions mate to shape a back plate.

### Claim 3 (depends on 1)

The system of claim 1, wherein the first and second portions mate to shape a compressor housing.

### Claim 4 (depends on 1)

The system of claim 1, wherein the plurality of fins is arranged outside or inside of the coolant chamber.

### Claim 5 (depends on 1)

The system of claim 1, wherein the first portion is coupled to the second portion with a sealing ring arranged therebetween.

### Claim 6

A compressor comprising:
a coolant chamber shaped via a first portion and a second portion, wherein the first portion is a solid continuous piece that seals the coolant chamber and comprises no passages, and the second portion comprises a plurality of fins extending into a volume of the coolant chamber,
wherein the coolant chamber is a first coolant chamber, further comprising a second coolant chamber, and wherein the first coolant chamber is arranged in a back plate downstream of a compressor blade and the second coolant chamber is arranged in a compressor housing upstream of the compressor blade relative to a direction of intake air flow.

### Claim 7 (depends on 6)

The compressor of claim 6, wherein the first portion and the second portion mate to form a back plate, and wherein the coolant chamber is arranged interior to surfaces of the back plate.

### Claim 8 (depends on 7)

The compressor of claim 7, wherein the second portion is further shaped to receive a compressor blade.

### Claim 9 (depends on 6)

The compressor of claim 6, wherein the first portion and the second portion mate to form a compressor housing, and wherein the coolant chamber is arranged between a volute and a compressor blade.

### Claim 10 (depends on 6)

The compressor of claim 6, wherein the first coolant chamber comprises a first plurality of fins and the second coolant chamber comprises a second plurality of fins.

### Claim 11 (depends on 6)

The compressor of claim 6, wherein the plurality of fins extends in a direction parallel to a direction of intake air flow.

### Claim 12 (depends on 6)

The compressor of claim 6, wherein each fin of the plurality of fins is circular and is radially spaced away from an adjacent fin.

### Claim 13 (depends on 6)

The compressor of claim 6, wherein each fin of the plurality of fins comprises a rectangular shape along a cross-section taken along a direction parallel to a direction of intake air flow.

### Claim 14

A system comprising:
a turbine and a compressor arranged along a common shaft, the compressor comprising a back plate arranged between the compressor and the turbine, the back plate comprising a first back plate portion and a second back plate portion adapted to physically couple and shape a first coolant chamber formed therebetween, wherein the first back plate portion is a solid continuous piece free of passages, and the compressor further comprising a compressor housing, the compressor housing comprising a first housing portion and a second housing portion adapted to physically couple and shape a second coolant chamber formed therebetween.

### Claim 15 (depends on 14)

The system of claim 14, wherein the second back plate portion is shaped to physically couple with an extreme end of the first housing portion, wherein a diffuser hub surface of the second back plate portion faces a diffuser shroud surface of the second housing portion, and wherein one or more of the diffuser hub surface and the diffuser shroud surface comprise vanes.

### Claim 16 (depends on 15)

The system of claim 15, wherein a compressor blade is arranged between the second back plate portion and the second housing portion, and wherein the compressor blade is physically coupled to the back plate.

### Claim 17 (depends on 16)

The system of claim 16, wherein the second coolant chamber is arranged between the compressor blade and a compressor volute.

### Claim 18 (depends on 14)

The system of claim 14, wherein each of the first coolant chamber and the second coolant chamber comprises a plurality of protrusions.
