TPMS Cooling Channels

- Lattice: Gyroid / Diamond

- Benefits: Max surface area, uniform flow, no hot spots

- Performance: +28% heat transfer, lower flow resistance

- Process: Monolithic print, no brazing/leaks

Hydrodynamic Pin Fin Design

- Geometry: Teardrop-shaped pin fin array

- Advantage: Minimizes flow separation vs. cylindrical pins → significantly lower pressure drop

- Result: Maintains high heat transfer while reducing pumping power or enabling higher flow rates

- Application: High-frequency heating systems. 　

- Material: Pure Copper (101% IACS). 　

- Geometry: Seamless conformal cooling channels. 　

- Advantage: Monolithic build eliminates brazing leaks. 　

- Result: High structural rigidity & extended service life.

IGBT Cooling – Beyond Forged Fins

- Limit: Forged fins hit bottleneck

- Innovation: 3D-printed micro-structures (bottom textures + spiral cones + horizontal strips)

- Gain: 30–40% higher thermal efficiency (same footprint)

- Replaces: Copper sheet heatsinks

- Design: Fin + needle/rectangular hybrids

- Function: Boosts surface area + guides flow

- Result: Significantly better thermal uniformity

- Target: 5× efficiency vs. copper plate

- Design: Irregular textures + spiral cones + horizontal strips

- Result: 6–7× gain (verified)

- Process: 3D-printed base + welded cover (hybrid)

- Conformal channels: Follow 3D heat source contour (not just 2D plane)

- Internal features: Fin/pin/needle hybrids maximize turbulence & surface area

- Outcome: Solves uneven heating in complex geometries—impossible with traditional machining
