Automobile air inlet channel assembly

Abstract

The invention discloses an automobile air inlet channel assembly. An air inlet grid is arranged on the side face of a shell, a first air outlet is arranged at the bottom, a rainproof hood is arrangedin the shell, and a drain opening is formed at the bottom of the rainproof hood. Multiple water baffles are distributed between two side baffles of the rainproof hood, and a second air outlet is formed between ever two adjacent water baffles. A water inlet and a water outlet are formed on the side baffle on one side, and a flow guide structure is arranged on the outer side of the side baffle. According to the automobile air inlet channel assembly, the flow guide structure is formed on the outer side of one side baffle, water intercepted and separated by the rainproof hood flows downwards to the drain opening from the flow guide structure on the outer side of the corresponding side baffle to be drained, water does not flow through an air inlet when flowing downwards, and therefore impact ofair inlet airflow is avoided; and the situation that water is coiled into an air inlet channel by airflow is avoided, water is drained more thoroughly, the water removal efficiency is higher, the situation that water is coiled into an air filter and wets filter paper of a filter element is avoided, and the filter efficiency of the filter element is ensured.

Description

technical field [0001] The invention relates to the technical field of air intake systems, in particular to an automobile air intake assembly applied to heavy trucks. Background technique [0002] As an important part of the intake system, the intake duct mainly removes water and dust from the air flow entering the intake system, and provides dry air to the air filter to prevent the moisture in the air flow from wetting the filter element . [0003] At present, the intake duct of the air intake grille structure used by heavy-duty vehicles can condense, collect and discharge the moisture entering the intake duct by adding a rain cover inside the intake duct; The moisture collected on the hood flows down along the front end on the side of the air inlet and drips to the drain outlet below. The moisture will flow downward through the air inlet. The air flow is drawn into the air intake duct, and the water removal efficiency is low. The moisture entering the air intake duct is ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the disadvantages of the above-mentioned existing air inlets, such as low water removal efficiency, easy moisture being drawn into the air filter, and wet filter paper, the applicant provides an automobile air inlet assembly with a reasonable structure and high water removal efficiency. High, moisture is not easy to get involved in the air filter
