Description

Engine cylinder cover with double-layer cooling water jacket structure Technical Field The utility model relates to the technical field of engine cylinder cover cooling, in particular to an engine cylinder cover with a double-layer cooling water jacket structure. Background The cylinder cover of the engine is arranged on the cylinder body, and the cylinder cover is in direct contact with high-temperature fuel gas generated during the working of the engine, so that the temperature of the cylinder cover is always at a higher level during the working of the engine, the cylinder cover bears larger heat load, the service life of the cylinder cover can be reduced, and the cylinder cover is required to be cooled through a cooling water jacket structure. However, when the existing cooling water jacket structure is used, due to the fact that the existing engine is of a multi-cylinder structure, the circulation distance of cooling liquid in the heat dissipation channel is long, cooling dead zones cannot be formed synchronously due to the fact that cooling liquid flow in each part in the heat dissipation channel, cooling effect is reduced, sediment is easily accumulated in the cooling water jacket after long-time use, cooling effect is affected, and popularization and use are inconvenient. The application provides an engine cylinder cover with a double-layer cooling water jacket structure, which aims to solve the problem. Disclosure of utility model The utility model aims to provide an engine cylinder cover with a double-layer cooling water jacket structure, which solves the problems that a cooling dead zone is formed due to a longer circulation distance of cooling liquid in a cooling channel in the prior art, and deposits are easy to accumulate in the cooling water jacket after long-time use, so that the cooling effect is reduced, the cooling effect is influenced and the using effect is poor. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides an engine cylinder cap of double-deck cooling water jacket structure, includes cylinder cap subassembly, cooling module and filter module, the cylinder cap subassembly includes cylinder cap main part and cylinder, the inside at the cylinder cap main part is seted up to the cylinder, the inside at the cylinder cap subassembly is seted up to the cooling module, the cooling module includes second passageway and pipeline, the inside at the cylinder cap main part is seted up to the second passageway, the top of pipeline fixed mounting cylinder cap main part, filter module fixed mounting is in the outside of cooling module, the filter module includes shell and filter, filter fixed mounting is in the inside of shell.
