Motor cooler housing for centrifugal turbo-compressor
5 March 2019
Through the use of additive manufacturing processes, it was possible to produce near-series prototypes with additive manufacturing for a more powerful blower generation for turbo radial compressors in a very short time.
Powerful and compact turbo radial blowers with speeds of up to 66,000 rpm are used for gas circulation in CO2 lasers. The motors are encased in a water-cooled aluminum casting with a cast stainless steel spiral.
For prototypes of the new, more powerful blower generation, heat sinks are to be upscaled and alternatively manufactured with additive manufacturing.
The optimization of the production of the prototypes takes place in the following process steps:
- Functional design - DfAM
- design consulting
- Prepare construction job
- Print raw parts
- Mechanical finishing
- Thermal post-treatment
By using additive manufacturing processes, TRUMPF was able to produce near-series prototypes with integrated cooling spirals for a more powerful blower generation for turbo radial compressors in a very short time.
What exactly was achieved?
- Short throughput time of fewer than 6 weeks
- Own technology practically applied
- No cost advantages for prototypes
- Remaining housing parts like the previous generation
