Description

[0002] The engine front cover is an important component of the engine. It is used to seal the engine cylinder block. The engine cylinder block is in a state of high temperature and high pressure during operation. Therefore, the material performance requirements for the engine cylinder block and the end cover are very high. However, since the end cover and the cylinder block are two different parts, the cylinder head and the cylinder block are misaligned due to heat. It is necessary to consider the heat dissipation of the end cover to ensure that it can be firmly packaged on the cylinder block.

[0003] The application number is 20232136685308. An engine front cover achieves heat dissipation by adding a cooling pipe, an external circulation pump and a heat sink. However, the additional components will increase the occupancy rate of the interior space of the vehicle, and no air cooling components are designed on the heat sink. The natural heat dissipation efficiency is too slow. The temperature of the coolant cannot drop quickly under long-term circulation, which will affect the heat dissipation efficiency of the front cover.

[0004] Therefore, in view of the above problems, we propose a front end cover which is beneficial to the heat dissipation of the engine. Utility Model Content
