Cooling ultra-small radius bend pipe for vehicle drive motors.
A pipe that simultaneously achieves a beautiful "extremely small bending radius" and a strict "press-fit outer diameter tolerance of 15 to 30 μm" with a center radius of 0.75D (Min).
By minimizing the bending parts of pipes, we can improve the layout flexibility of onboard inverters and motors. *We have a proven track record with domestic HEVs and PHEVs, currently producing around 160K units annually! By eliminating issues caused by welding and achieving high press-fit outer diameter tolerances, we can enhance quality. Bending: Bending center R = 0.75D (Min) Press-fit: Tolerance range = 15μ (Min) Flattening: Cross-sectional area reduction rate = 13% (Min) Example of minimal R bending achievements: Φ25.4 × t1.6 CR20 = 0.8D Φ17.0 × t1.2 CR13 = 0.76D *CR = Bending center R *0.6D is also possible under certain conditions "Press-fit outer diameter tolerance" Proven track record of guaranteeing a range of 15μ after surface treatment This can reduce the limitations of piping layouts for units requiring liquid cooling and also contribute to reducing pressure loss.
