A guard plate beneficial to improving thermal management performance of engine mid-mounted chassis

Abstract

The invention relates to a protective plate beneficial to improving thermal management performance of a chassis with a middle-mounted engine. The protective plate comprises a protective plate main body portion, wherein a reinforcing rib portion, an installation portion, a grid hole portion and an upward-warping diversion portion are arranged at the upper portion of the protective plate main body portion, the whole protective plate main body portion is straight and flat, a flat and straight transition plate is arranged between the upward-warping diversion portion and the grid hole portion, two suspension structure avoiding grooves which avoid a suspension structure are formed in the left side of the protective plate main body portion and the right side of the protective plate main body portion respectively, and avoiding groove grid holes are formed in the left avoiding groove and the right avoiding groove in the directions right facing towards air flow directions respectively. The protective plate can actively guide the air flow, cooled air is closer to the chassis, backflow at the tail portion of the engine is reduced, flowing stagnation in a thermal source area is eliminated, the flowing condition around an engine body is effectively improved, the flowing speed of air on the surfaces of parts of the engine body is increased, the temperature of air on the surfaces of the parts is lowered, the thermal management performance of the chassis is greatly improved, and the wind resistance coefficient of the whole automobile chassis is further lowered to a certain extent.

Description

technical field [0001] The invention belongs to the field of automobile bodies, and in particular relates to a thermal management guard plate for a mid-engine chassis. Background technique [0002] As the automobile market has higher and higher requirements for car appearance and later maintenance and repair, many existing cars have begun to add chassis guards. The guards are located under the chassis and have the functions of covering trivial parts of the car body and keeping the engine body clean. However, many chassis guards do not fully consider their impact on the overall airflow of the chassis, and the structural design of the guards is unreasonable, causing the cold fluid of the chassis to stay away from the car body, causing severe backflow at the rear of the engine room, and forming a flow stagnation area at the rear of the engine body. It is not convenient for the engine room to dissipate heat, and there are many overheated components, which do not meet the heat da...

[0002] As the automobile market has higher and higher requirements for car appearance and later maintenance and repair, many existing cars have begun to add chassis guards. The guards are located under the chassis and have the functions of covering trivial parts of the car body and keeping the engine body clean. However, many chassis guards do not fully consider their impact on the overall airflow of the chassis, and the structural design of the guards is unreasonable, causing the cold fluid of the chassis to stay away from the car body, causing severe backflow at the rear of the engine room, and forming a flow stagnation area at the rear of the engine body. It is not convenient for the engine room to dissipate heat, and there are many overheated parts, which do not meet the heat damage requirements, and the drag coefficient of the vehicle chassis is relatively large, which affects the performance of the vehicle

The existing chassis guard plate has a single function, does not meet the requirements of thermal management performance, and does not have the ideal effect of air guide and resistance reduction
