Technical Field
The invention relates to the technical field of radiators, in particular to an optimized structure of a segment radiator for a high-power locomotive.
Background
With the need of heavy load and high speed of passenger transport of railway freight, locomotives are developed to single machines and high power, which requires better performance of locomotive related components. When the internal combustion engine is used under the condition of severe environment (high temperature, large sand wind and high altitude), the strict requirements are put on an auxiliary system of the locomotive. The cooling system of the diesel locomotive is an important component of the diesel locomotive and plays an important role in the economic performance and reliability of the diesel locomotive. The main function of the locomotive cooling system is to keep the cooling water and engine oil of the locomotive diesel engine in a proper temperature range through various heat exchange measures, keep the hydraulic transmission working oil of the locomotive in a proper temperature range and ensure that the temperature rise of the motor winding of the electric transmission locomotive is below an allowable value.
Radiator has been developed for nearly a hundred years, and performance of the radiator has been improved, but it has been delayed a lot with respect to the progress of the engine. The heat dissipation state of the existing radiator is not slightly different from the ideal state, so that the optimization of the radiator structure is very necessary, meanwhile, how to optimize is also a very important problem, when the radiator is manufactured and selected, the radiator cannot be only standardized by one factor, and various factors must be comprehensively considered, so that a more comfortable environment can be obtained, and unnecessary waste is reduced. Therefore, the working performance of the radiator has become a bottleneck for restricting the development of the cooling system, and research, development and innovation of the radiator have become important points of development.

Detailed Description
The invention is further described below with reference to the drawings.
As shown in fig. 1-2, an optimized structure of a fin-type radiator for a high-power locomotive comprises a radiating fin 1, a diamond-shaped windowed radiating fin 101, a round windowed radiating fin 102, a round windowed 2, a diamond-shaped windowed 3 and a radiating tube bundle 4.
The utility model provides an optimized structure that can be used to high-power locomotive's gilled tube radiator, this radiator is applied to high-power locomotive's cooling system for cooling intercooler and engine oil heat exchanger, and the radiator comprises heat dissipation tube bank 4 and the parallel fin 1 of cover on heat dissipation tube bank 4, and heat dissipation tube bank 4 can adopt one or more, and heat dissipation tube bank 4 dislocation set when adopting a plurality of to open on fin 1 has diamond or circular window structure. There are two types of media that pass through a heat sink: the coolant and cooling air are two separate cycles. The coolant flows through the tube bundles and the heat absorbed by the coolant in the copper tubes transfers both internal and external heat by heat conduction between the tube walls and the fins. The fan takes heat away by sucking in cooling air. The radiator fin 1 and the radiator tube bundle 4 are made of copper, wherein the fin structure is formed by alternately superposing a layer of diamond-shaped windowed radiating fins 101 and a layer of round-windowed radiating fins 102.
The diamond-shaped windowed radiating fin 101 comprises a radiating fin main body, a group of diamond-shaped windowed radiating fins 3 are arranged on the radiating fin main body, the round windowed radiating fin 102 comprises a radiating fin main body, a group of round windowed radiating fins 2 are arranged on the radiating fin main body, and the diamond-shaped windowed radiating fins 3 between adjacent radiating fins 1 are staggered with the round windowed radiating fins 2.
The radiator geometry parameters are shown in table 1, wherein U is the fin length, V1 is the high temperature portion fin width, V2 is the low temperature portion fin width, lb is the diamond-shaped fenestration length, ld is the diamond-shaped fenestration width, fp is the distance between fins, δ is the fin thickness, Φ1 is the circular tube diameter, Φ2 is the circular fenestration diameter.
TABLE 1
In order to illustrate that the heat dissipation effect of the windowed fin of the radiator is better than that of the windowed fin of the radiator, the windowed fin and the windowed fin of the radiator are calculated to illustrate comparison under the same working condition, and the calculation results are shown in table 2.
TABLE 2
It is clear from the figure that after the diamond holes are formed, the heat dissipation performance of the radiator is obviously improved.
To illustrate that the heat dissipation amounts of the staggered round and diamond windowed are higher than those of the pure round and diamond windowed, we performed a comparative calculation for the three cases, and the calculation results are shown in table 3.
TABLE 3 Table 3
It is clear from the table that the heat dissipation effect in use of only the diamond window or only the circular window is far less than that of the cross-over diamond window and circular window. Because the windows intersecting different shapes have a greater disturbance to the cooling airflow, more heat can be carried away.
