Creating a new generation heat exchanger – more compact and efficient than a standard plate heat exchanger.
This is in response to the needs of the automotive and aerospace industries, where these very parameters are crucial.
Instead of traditional exchanger plates, we used a Triply Periodic Minimal Surface (TPMS) structure.
This unique structure further turbulises the flow, resulting in intensified heat transfer.
- Reduction in volume by 27%
- Increase in efficiency relative to a standard heat exchanger by more than 10%.
- Material: 316L stainless steel
- Technology: 3D printing using LPBF technology
Start of work
The Spes3D engineering team, led by Krzysztof Kus, took up the challenge and started the process of designing a heat exchanger using a gyroidal TPMS (Triply-Periodic Minimal Surface) structure instead of one of the traditional solutions used in heat exchangers. We began the work by analysing and selecting the appropriate manufacturing technology – LPBF 3D printing in stainless steel.
We carried out a series of computer simulations to select, print and carry out laboratory testing of a prototype of the most promising heat exchanger variant.
