Description

Lightweight aluminum alloy engine body housing Technical Field The utility model relates to the technical field of engine body covers, in particular to a lightweight aluminum alloy engine body cover. Background The engine body housing is an important component part in an automobile and an aeroengine, and is mainly used for protecting internal components of the engine, ensuring normal operation of the engine and improving safety. The modern engine housing is increasingly made of aluminum alloy materials, and the weight of the whole engine is reduced and the fuel efficiency is improved due to the characteristics of light weight and high strength. In the prior art, the engine inevitably generates heat in use, and the normal use of the engine can be guaranteed only in a low-load environment by a conventional fin heat dissipation mode, the heat dissipation effect is limited in a high-load environment, the normal use of the engine in a high-load scene can be effectively guaranteed by additionally installing liquid cooling heat dissipation outside the engine, but the weight of an engine housing is increased due to additionally installing liquid cooling, and the weight of the housing is affected. Disclosure of utility model The application provides a light aluminum alloy engine housing, which is used for improving the heat dissipation performance of the housing while ensuring the light aluminum alloy engine housing. The technical aim of the utility model is realized by the following technical scheme: a lightweight aluminum alloy housing shell comprising: The cylinder body is provided with a mounting groove on the outer wall thereof, and an S-shaped flow passage is arranged on the inner wall of the mounting groove; The air guide sleeve is wrapped on the outer side of the cylinder body, the air guide sleeve is connected with the cylinder body through the fastening unit, the outer wall of the air guide sleeve is respectively provided with a water inlet and a water outlet, and the air guide sleeve completely covers the mounting groove, so that the water inlet and the water outlet are respectively arranged at two ends of the flow channel; and the cooling fins are arranged on the outer wall of the air guide sleeve at intervals from top to bottom and are used for improving the cooling efficiency of the air guide sleeve. Further, the kuppe mainly comprises curb plate and intermediate lamella, and the curb plate is provided with two, and two opposite one sides all are protruding to be formed with the insert, and the slot that is used for holding the insert has all been seted up to the both sides of intermediate lamella. Further, a first sealing gasket is sleeved on the outer side of the insertion part, and the first sealing gasket is attached to the side wall of the slot. Further, a first positioning hole is formed in the outer wall of the middle plate, close to the slot, a second positioning hole is formed in the position, corresponding to the first positioning hole, of the insertion portion, a threaded hole is formed in the position, corresponding to the first positioning hole, of the inner wall of the mounting groove, a bolt is arranged in the first positioning hole, and the bolt sequentially penetrates through the first positioning hole and the second positioning hole to be connected with the threaded hole.
