Method for preparing novel engine dust cover plate

Abstract

The invention provides a method for preparing a novel engine dust cover plate. The novel engine dust cover plate comprises a main cover plate and side cover plates, wherein the main cover plate comprises a soundproof chamber and cavities, the soundproof chamber is formed in the middle of the main cover plate, the cavities are formed at the two ends of the soundproof chamber, the side cover platesare installed in the cavities, one end of each side cover plate connected with the corresponding cavity is provided with a limiting plate, and each side cover plate is made up of sub-plates connectedthrough connectors. As for the novel engine dust cover plate, as the sound soundproof chamber is formed in the middle of the main cover plate through the structural connection between partitions, on the one hand, the soundproof chamber can appropriately block the noise emitted by the engine, and on the other hand, the soundproof chamber makes the thickness of the main shell plate have a place forheat dissipation; as the cavities are formed at the two ends of the main cover plate, side cover plates made up of the connected sub-plates are arranged in the cavities, and meanwhile vent holes are formed in and dust screens are arranged on the side cover plates, the internal air convection is realized, the cooling effect is good, and a certain amount of dust can be effectively blocked by the screens.

Description

technical field [0001] The invention relates to a novel preparation method of an engine dust cover plate. Background technique [0002] At present, when the car is moving, the temperature in the engine compartment is the highest, and in summer, the temperature can reach more than 120°C. In high-temperature seasons or high-temperature regions, if the heat cannot be dissipated in time, it will cause the water tank to boil. Therefore, in summer, it can often be seen that some vehicles are parked on the side of the road due to the boiling of the water tank, and the engine hood is opened to dissipate heat. The engine cover is sealed to the engine, resulting in poor heat dissipation of the engine, which may easily cause the water tank to boil and affect the normal operation of the engine. At the same time, the engine is often in a high temperature state, and the engine is easily burned out; at the same time, the reverberation sound field in the engine compartment is an important ...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is that the engine cover plate is sealed to the engine, resulting in poor heat dissipation of the engine, which may easily cause the water tank to boil and affect the normal operation of the engine. The sound field is an important external noise source. In the reverberation sound field in the engine compartment, there are sound waves emitted by the engine, sound waves reflected inward by the engine compartment wall and sound waves radiated by vibration of the engine compartment wall.
