Embodiment Construction

[0015] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0017] A curved pipeline structure that suppresses flow distortion, such as figure 1 As shown, it includes a curved pipe body 1. The curved pipe body 1 is composed of a plurality of branch pipes and a main pipe. The inside of the curved pipe body 1 is arranged with guide fins arranged at the junction of the elbow pipes according to the curved shape of the pipeline. 2.

[0018] Arrange one diversion fin 2 at the intersection of two diversion branch pipes, and arrange 1 to 3 diversion fins 2 at the junction of each diversion branch pipe according to the pipe diameter and diversion requirements, such as image 3 As shown, in this embodiment, two diversion ribs 2 are arranged at the juncti...

Abstract

The invention provides a bent pipeline structure capable of inhibiting flow distortion. A bent pipeline is mainly composed of a bent pipe body and flow guiding rib pieces in the pipe body, and the flow guiding rib pieces are arranged at the junction of the bent pipe according to the bent shape of the pipeline and used for guiding gas which is distributed or gathered in the pipeline. By means of the flow guiding rib pieces, flowing of a fluid at the junction of the bent pipe can be improved, flowing mutual interference in the distributing / gathering position is avoided, especially when two flowdistributing branch pipes are connected with inlets of two supercharger compressors correspondingly, the flow distortion in an existing pipeline due to reverse rotation of impellers of the two compressors can be inhibited remarkably, and the purpose of improving the system efficiency is achieved.

Description

technical field [0001] The invention belongs to the technical field of exhaust gas turbocharging, and in particular relates to a curved pipeline structure for suppressing flow distortion. Background technique [0002] The requirements of high power density and plateau power recovery of internal combustion engines require continuous improvement and optimization of the performance of the supercharging system, so that the supercharging system can be well matched with the engine. Bent pipes are commonly used inside the booster system and connected to the booster system and the engine. [0003] The traditional connecting elbow often produces flow mutual interference at the confluence of the branch pipe, which increases the flow loss and reduces the system efficiency. Therefore, it is necessary to control the flow of gas in the connecting pipeline, especially for the double-row supercharger arranged on the V-type and other non-inline engines, and the three-way connecting pipe wit...
