Technical Field

Background
With the requirement of heavy load of railway freight and high speed of passenger transportation, the locomotive is developed to a single machine and high power, which requires that the performance of relevant parts of the locomotive is better. When the diesel locomotive is used under the conditions of severe environment (high temperature, large sand storm and plateau), the harsh requirements are put forward on the auxiliary system of the locomotive. The cooling system of the internal combustion locomotive is an important component of the internal combustion locomotive and plays an important role in the economic performance and reliability of the internal combustion locomotive. The locomotive cooling system has the main functions that through various heat exchange measures, cooling water and engine oil of a locomotive diesel engine are kept in a proper temperature range, hydraulic transmission working oil of the locomotive is kept in a proper temperature range, and the temperature rise of a motor winding of an electric transmission locomotive is guaranteed to be below an allowable value.
Radiators have been developed over the last hundred years, and although the performance of radiators has improved substantially, it has lagged considerably with respect to the progress of engines. The heat dissipation state of the existing radiator has a little difference from the ideal state, so the radiator structure is very necessary to be optimized, and meanwhile, how to optimize is also a very important problem. Therefore, the working performance of the heat sink has become a bottleneck restricting the development of the cooling system, and the research, development and innovation of the heat sink become the key point of the development.

Detailed Description
The invention is further described with reference to the accompanying drawings.
As shown in fig. 1-2, an optimized structure of a gilled tube radiator for a locomotive comprises fins 1, rhombic heat dissipating fins 101 with windows opened, round heat dissipating fins 102 with windows opened, round heat dissipating fins 2 with windows opened, rhombic heat dissipating fins 3 with windows opened, and heat dissipating tube bundles 4.
The optimized structure of the locomotive gilled tube radiator is applied to a cooling system of a high-power locomotive and used for cooling an intercooler and an engine oil heat exchanger, the radiator consists of a radiating tube bundle 4 and parallel radiating fins 1 sleeved on the radiating tube bundle 4, the radiating tube bundle 4 can adopt one or more than one, the radiating tube bundles 4 are arranged in a staggered mode when a plurality of radiating tube bundles are adopted, and a rhombic or circular windowing structure is arranged on the radiating fins 1. There are two types of media that pass through the heat sink: the coolant and cooling air are two separate circuits. The coolant flows through the heat sink tube bundle and the heat absorbed by the coolant in the copper tubes transfers internal and external heat by thermal conduction between the tube walls and the heat sink fins. The fan takes away heat by drawing in cooling air. The radiator fins 1 and the radiating pipe bundles 4 are made of copper, wherein the fin structure is formed by alternately overlapping a layer of rhombic windowing radiating fins 101 and a layer of circular windowing radiating fins 102.
The rhombic windowing radiating fin 101 comprises a radiating fin main body, a group of rhombic windowing 3 is arranged on the radiating fin main body, the circular windowing radiating fin 102 comprises a radiating fin main body, a group of circular windowing 2 is arranged on the radiating fin main body, and the rhombic windowing 3 and the circular windowing 2 between adjacent radiating fins 1 are staggered.
The geometrical parameters of the heat sink are shown in table 1, wherein U is the fin length, V1 is the high temperature part fin width, V2 is the low temperature part fin width, Lb is the length of the diamond window, Ld is the width of the diamond window, Fp is the distance between the fins, δ is the thickness of the fins, Φ 1 is the diameter of the circular tube, and Φ 2 is the diameter of the circular window.
TABLE 1
In order to illustrate that the heat dissipation effect of the radiator fin windowing is better than that of the radiator fin without windowing, windowing and non-windowing are calculated under the same working condition to illustrate comparison, and the calculation results are shown in table 2.
TABLE 2
It can be clearly seen from the figure that the heat dissipation performance of the radiator is obviously improved after the diamond holes are formed.
To illustrate that the heat dissipation of the staggered round-shaped windowing and the diamond-shaped windowing is higher than that of the pure round-shaped windowing and the diamond-shaped windowing, a comparison calculation is performed for three cases, and the calculation results are shown in table 3.
TABLE 3
It is clear from the table that the heat dissipation effect of the window with only the diamond shape or the window with only the round shape in use is far different from the heat dissipation effect of the window with the diamond shape and the round shape. More heat can be taken away because the crossing of windows of different shapes has a greater disturbing effect on the cooling air flow.
