Turbocharger system and turbocharger air conveying system

The utility model provides a turbocharger system, which comprises a flexible pipeline and a plurality of shrinkage rings, wherein the flexible pipeline is provided with a longitudinal elastic body which longitudinally extends between a first end part and a second end part, and the first end part and the second end part are attached to the corresponding turbocharger device; the shrinkage rings are longitudinally spaced between the end parts; the radial compression force is applied to each shrinkage ring around the pipeline along the corresponding circumferential direction; the shrinkage rings are made of thermoplastic material by dies and are arranged in a concentric shape by buckle hooks; the distance between the shrinkage rings is enough to increase and limit the size of the pipeline under the operation pressure of the turbocharger to the density smaller than 20%. The utility model also provides a turbocharger air conveying system. The turbocharger system has the advantage that the elastic pipeline is made of common rubber material, and the expansion of the pipeline is limited by the lower cost, so as to overcome the defects of the prior art.
