Description

Technical Field

[0001] This invention relates to the technical field of vehicle cooling system mounting structures, and more specifically to an automotive oil cooler mounting assembly. Background Technology

[0002] During vehicle operation, lubricating oil in various lubrication systems, powered by an oil pump, transfers heat to the cold side of the oil cooler via the hot-side channels. Meanwhile, cooling water or cool air carries away heat through the cold-side channels, achieving heat exchange between the hot and cold fluids and ensuring the lubricating oil is at its optimal operating temperature. This includes cooling engine oil, automatic transmission oil, and power steering oil. In recent years, the new energy vehicle industry has seen rapid growth. Due to the increasingly complex demands of new energy vehicles on heat exchange systems, the types and numbers of heat exchangers in the front compartment are increasing. Oil coolers, condensers, low-temperature radiators, and high-temperature radiators have significantly different performance requirements and different requirements for the working environment on the air side. This has led to the proposal of… Figure 1 The arrangement shown places the oil cooler 2 on the front side of the front longitudinal beam 1, spaced apart from the front compartment heat exchanger 6. However, the presence of a heat-insulating structure between the front compartment heat exchanger 6 and the oil cooler 2 still causes some interference. Furthermore, the oil cooler 2 is connected to the front longitudinal beam 1 via an oil cooler bracket 3', which has a complex structure, is inconvenient to manufacture, and is also inconvenient to install the oil cooler 2 on the bracket 3'. Therefore, the installation structure of the oil cooler 2 needs to be redesigned to reduce the mutual interference between the oil cooler 2 and the front compartment heat exchanger 6, while also facilitating the installation of the oil cooler 2.
