Specific embodiment
In the following, being further described in conjunction with substantive distinguishing features and advantage of the example to the utility model, but this is practical new Type is not limited to listed embodiment.
As shown in Figures 1 to 6, a kind of cooling system of oil-immersed transformer of the present embodiment includes fuel tank 1 and heat dissipation group Part 2, radiating subassembly 2 are connect with fuel tank 1.The radiating subassembly 2 includes heat-sink unit 21 and fan 22, and the setting of fan 22 is being radiated 21 top of unit.The heat-sink unit 21 includes oil inlet pipe 3, flowline 4 and cooling fin 5, and oil inlet pipe 3 and the setting of flowline 4 exist It 5 both ends of cooling fin and is connected to the chamber 51 in cooling fin 5.Cooling fin 5 is vertically set between oil inlet pipe 3 and flowline 4, into One end of oil pipe and flowline is connected to fuel tank, and muti-piece cooling fin 5 is parallel and interval setting, oil inlet pipe and flowline respectively with oil Case connection.In above-mentioned technical proposal, cooling oil is stored in fuel tank, after the temperature of cooling oil rises, cooling oil flows into oil inlet pipe, It is returned in fuel tank subsequently into cooling fin, then by flowline.By the way that fan is arranged, heat dissipation effect can be further enhanced. Through the above technical solutions, cooling oil can be made to be capable of forming circulation cooling, avoid temperature excessively high, improving radiating effect.
In the present embodiment, the radiating subassembly 2 includes dust excluding plate 23, and dust excluding plate 23 is arranged above fan 22, to subtract The dust gathered on few fan, protects fan, and dust excluding plate is equipped with mesh, passes through convenient for air-flow.
In the present embodiment, the fan 22 is located at 5 top of cooling fin, forms airflow channel 52, wind between abutting fins 5 Fan, so that the air-flow for enabling fan to blow out is smooth by airflow channel, the heat of cooling fin is taken away towards airflow channel.
In the present embodiment, heat-sink unit 21 includes drain valve 6, and the setting of drain valve 6 is in 4 end of flowline, consequently facilitating will Cooling oil is discharged by drain valve 6.
In the present embodiment, the oil inlet pipe 3 is located at 1 top of fuel tank, and flowline 4 is located at 1 lower section of fuel tank, to work as cooling oil After temperature rises expansion, after liquid level rises to oil inlet pipe position, cooling oil can be flowed out from oil inlet pipe.Those skilled in the art can Know, the mode of forced circulation can also be used in cooling oil, and oil pump can be arranged on oil inlet pipe, and cooling oil is sucked oil inlet pipe.
