[0002] The cooling system is an important part of the thermal management of the entire vehicle and has a great impact on the reliability and economy of the automobile powertrain. The function of the automobile cooling system is to keep the powertrain within the appropriate operating temperature range under all working conditions. Most modern automobiles, especially passenger car powertrains, use a forced circulation water cooling system, which uses a water pump to increase the pressure of the coolant and force the coolant to circulate in the cooling system. With the improvement of vehicle performance, the increase in the size of supercharged engines and automatic transmissions and the increase in other accessories in the front engine compartment, the installation space of the water cooling pipes of the front-end cooling system has been gradually compressed, and the layout of the water pipes and the matching dimensions of the surrounding clearances are difficult to control. The current automobile engine cooling circulation loop and the transmission oil cooler cooling circulation loop are set separately, which takes up too much space in the vehicle body and cannot meet the layout requirements.

[0003] After searching, the applicant found that the Chinese patent document with publication number 110685790A disclosed a car engine cooling pipe fixing mechanism on January 14, 2020, including a cooling pipe main body, a fixing mechanism main body and a fixing adjustment mechanism.
