[0031] Embodiment: as shown in the figure, the utility model provides a kind of reinforced sheet type radiator technical scheme: Figure 1 - Figure 6

[0032] ​As Figures 1 to 3 shown, the finned heat sink includes fins 1, reinforcing ribs 2, an oil inlet pipe 3, an oil outlet pipe 4 and helical blades 5, one end of the fins 1 is welded with the oil inlet pipe 3, the other end of the fins 1 is welded with the oil outlet pipe 4, the helical blades 5 are inserted into the oil inlet pipe 3, the helical blades 5 and the oil inlet pipe 3 are threadedly connected by screws, the oil inlet pipe 3 and the oil outlet pipe 4 are communicated, a plurality of fins 1 are arranged between the oil inlet pipe 3 and the oil outlet pipe 4, and both sides of all the fins 1 are welded with the reinforcing ribs 2.

[0033] The reinforcing ribs 2 can well support the overall frame structure of the heat sink, prevent deformation and damage due to vibration and external force generated during the operation of the transformer, and affect the heat dissipation effect. During heat dissipation, hot oil enters the oil inlet pipe 3 from the inlet of the oil inlet pipe 3, flows downward along the helical blades 5, and at the same time, under the action of centrifugal force, accelerates into the fins 1. The hot oil flows in the fins 1, exchanges heat with the fins 1, and achieves the effect of heat dissipation. Finally, the heat-exchanged hot oil flows into the oil outlet pipe 4 to end the heat dissipation.

[0035] The recessed lines 11 on the upper and lower surfaces of the fins 1 coincide inside the fins 1, forming a strip of oil conveying channels between each other. The oil conveying channels formed between the recessed lines 11 increase the contact area of the hot oil with the fins 1, thereby improving the heat dissipation efficiency. At the same time, by changing the shape, size and position of the recessed lines 11, different oil conveying channels can be formed to ensure the uniform distribution of hot oil in the fins 1, prevent local overheating and uneven heat dissipation, and prolong the service life of the heat sink.
