Background

The oil cooler is one of the important components of an engine cooling system, is generally arranged in parallel with a radiator, and is equipment for reducing the temperature of engine oil by utilizing the principle of heat exchange. According to the medium difference of exchange, the oil cooler divide into air-cooled and water-cooled, and two kinds of modes are that the internal energy of machine oil transfers for cooling medium through the heat transfer to realize the purpose that reduces the machine oil temperature, the viscosity of machine oil can become low along with the rising of temperature, thereby has reduced the lubricity of machine oil, in case the machine oil lubrication degree is not enough, can cause mechanical wear to strengthen, greatly reduced the working life of engine. The oil cooler sealing ring is used for sealing an oil inlet and an oil outlet of the oil cooler, so that the engine oil is not leaked while being cooled. Due to the working condition of the oil cooling sealing ring, the oil-resistant and high-temperature-resistant sealing ring has higher requirements on the oil-resistant and high-temperature-resistant performance of the sealing ring, and has higher requirements on the structural design of the sealing ring for the sealing performance. Under the condition, how to develop an oil-cooled sealing ring with good sealing performance, durability and reliability is one of the important works of the localization of the current domestic sealing industry. Therefore, the research and development of the high-performance oil cooling sealing ring have important significance for the aspects of market development in the future, improvement of market competitiveness of the sealing ring per se and the like.

At present, the sealing mode of the oil cooler is complicated in design schemes of various large main engine plants and engine plants, the schemes are numerous, for example, O-shaped fluorine rubber sealing rings are adopted for separate sealing, rubber is adopted for wrapping metal gaskets for vulcanization molding, the rubber sealing rings are adopted for being arranged in grooves of the oil cooler and the metal gaskets are adopted for sealing, and the sealing modes are not ideal in aspects of sealing effect, design and processing cost, installation efficiency, sealing durability and the like and have certain defects.
