Description

Technical Field

[0001] The invention relates to the technical field of a vehicle cooling system mounting structure, and more particularly to an automobile oil cooler mounting assembly. Background Art

[0002] When the vehicle is driving, the lubricating oil in each major lubrication system relies on the power of the oil pump to pass through the hot side channel of the oil cooler to transfer the heat to the cold side of the oil cooler, while the cooling water or cold air takes away the heat through the cold side channel of the oil cooler, realizing heat exchange between cold and hot fluids, ensuring that the lubricating oil is at the most suitable working temperature, including the cooling of engine lubricating oil, automatic transmission lubricating oil, power steering lubricating oil, etc. In recent years, the development of the new energy vehicle industry has been getting better and better. Due to the increasingly complex requirements of new energy vehicles for heat exchange systems, the types and quantities of front cabin heat exchangers have increased. The performance requirements of oil coolers, condensers, low-temperature radiators and high-temperature radiators are quite different, and there are also different requirements for the working environment on the wind side. It has been proposed that Figure 1 The arrangement structure shown in the figure installs the oil cooler 2 on the front side of the front longitudinal beam 1 and arranges it in a spacing manner with the front cabin heat exchanger 6. However, there is a separation insulation structure between the front cabin heat exchanger 6 and the oil cooler 2, which still has some influence. Moreover, the oil cooler 2 is installed and connected to the front longitudinal beam 1 through the oil cooler bracket 3', and the oil cooler bracket 3' has a complex structure and is not convenient to manufacture. At the same time, it is not inconvenient to install the oil cooler 2 on the oil cooler bracket 3'. Therefore, it is necessary to improve the design of the installation structure of the oil cooler 2 to reduce the mutual influence between the oil cooler 2 and the front cabin heat exchanger 6, and facilitate the installation of the oil cooler 2.
