Abstract
The cooling system is an important part of engine, it has strong influences on the power, economy and dependability of engine. With increasing in speed and power of engine, the demand to cooling system is higher, so the design and research on the cooling system of engine is also becoming more and more advanced. Under the precondition that the necessary trend that the cooling efficiency is higher and the energy consumption is lower.
The radiator is the core part of cooling system, its structure is an important influent factor of heat transfer ability, and the quality of the radiator has very great influence on the whole cooling system. This article has analyzed the available ways to improve the radiator efficiency in theory, and has the contrast research on the influence between structure of the tube and corrugated fin radiator and the radiation’s performance through experiment. The arrangement of cooling water pipe is strong influence on heat transfer ability, in a situation that other structure parameter is the same, the quantity of cooling water pipe will have great influence on the performance of the radiator, but the air resistance increases by vast scale also. When cooling water pipe is more than 3 platoon, the heat transfer capacity not as so vast as the increase of the whole area of heat transfer of radiator, the result of heat transfer is transfer is general, but the increases of air resistance is not obvious.
The design and matching of cooling system affects the performance of engine directly. In this article, the radiator and the cooling fan has been matched for cooling system of one kind of remodeling vehicles, and the designing calculation has been done and the computation has been checked up, and the structure of the cooling system has been optimizing designed.
