Description

Technical Field

[0001] The present invention relates to the technical field of vehicle cooling systems, and particularly relates to a new type of integrated cooling system for hybrid trucks and a vehicle equipped with the cooling system. Background Art

[0002] With the rapid development of China's economy, the implementation of the national four-stage fuel consumption policy, and users' demands for high vehicle attendance rate, large horsepower, economy, and ground clearance, higher requirements are put forward for the cooling systems of light trucks. The traditional "narrow and tall" cooling module cannot guarantee the vehicle passing performance of large-horsepower models, and it is necessary for the fan to work for a long time to ensure the heat dissipation requirements of the engine, which has an adverse impact on the vehicle fuel consumption to a certain extent.

[0003] In order to control the vehicle development cost of existing light trucks, most cooling systems do not design a filling and degassing system, and adopt a side-mounted overflow tank scheme to collect and compensate the coolant. This scheme is prone to incomplete degassing of the cooling system, and the engine coolant has bubbles for a long time during the circulation process, which is easy to cause corrosion of the water pump and cylinder head. Moreover, when the bubbles accumulate to a certain extent, there is a risk of accidental high-temperature boiling of the whole vehicle.

[0004] Most of the existing cooling module suspensions adopt two-point suspensions and are fixed on the frame wing surface through soft pads. Although this scheme has a simple structure and is easy to assemble and repair, both two-point suspensions are designed at the middle position of the cooling module assembly. Under special working conditions of the vehicle, there is a resonance risk at the four corners of the cooling module, a risk of liquid leakage at the four corners of the radiator, and a large vibration amount of the cooling module assembly, which is easy to cause dynamic interference wear between the wind ring and the fan and there is a risk of fan blade fracture.

[0005] In summary, the existing vehicle cooling systems still have the following technical problems: Components such as radiators, intercoolers, and expansion tanks in the existing cooling system technical solutions are limited by the industry development level and lack an integrated layout, resulting in limited vehicle expansion. Moreover, component procurement requires separate procurement and transportation of sub-components, increasing the types and procurement costs of components, which is not conducive to centralized production and management. With the strict implementation of national regulations, the vehicle self-weight has become a hot topic in the industry. Therefore, it is necessary to develop a cooling system with an integrated layout, lightweight, high performance, and reliability, which is an urgent technical problem to be solved in this field. For this reason, it is necessary to propose a new type of integrated cooling system for hybrid trucks and a vehicle equipped with the cooling system to provide a new technical solution to solve the technical problems mentioned in the above patents.
