Abstract
Oil cooler is an important component parts of diesel engine, it's good or bad performance of the diesel engine directly affect the work of the diesel engine performance. Therefore, the design of the oil cooler is a very important aspect of diesel engine design process. And in recent years, with the supercharged diesel engine technology, matched with the diesel engine in cold technology has made considerable progress. Produce such as cold-rolled finned tube cooler such as the new cooler. At the same time, diesel engine oil cooler has also been a corresponding development. This article focuses on cold-rolled finned tube oil cooler of diesel engine to a general principle, in view of the role of engine oil cooler, the installation location and type of oil cooler design, completion of the oil cooler and heat analysis of the principle of thermal lubrication system cycle model to determine the engine oil cooler heat dissipation, the design of plate-fin oil cooler parts of the main study of plate-fin cooler component, the classification and the role of fin, plate-fin cooler features, One design of stainless steel plate-fin oil cooler structure, to determine the structure and fin-chip design, chip type, the design of shell and other parts, including engine oil cooler on the geometric characteristics of control analysis, calculation and control of geometric characteristics oil cooler and the thermal hydraulic calculation, the final design of the oil cooler to check the calculation. The design of the structure of oil coolers, oil coolers for the production process to do a simple design, master plate-fin oil cooler of the production process and vacuum brazing of the relevant circumstances.
