Abstract: A flat pipe with variable flow capacity comprises a main body shaped as a flat tube wherein opposing ridges are installed at the inner upper and lower positions of the main body, and thin-film spacers are installed between said pairs of ridges, forming multiple passages in the main body. Due to the flexibility of the thin-film spacers, the passages of the main body may stretch to a larger diameter to adjust to increased flow. If the flow is significantly enlarged, the main body will flex at the ridges causing the thin-film spacers to separate which in turn opens flow to the main body, essentially creating one main passage with a large diameter. When flow is stopped or decreased, the main body will restore elastically and resume shape as a flat pipe. According to the above, the present invention discloses a pipe which is easily stored and prevents twisting which could result in deformation, breakage and flow interference.
