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