On oil pipe, the side of the fin is provided with ventilating duct, and fan is provided with the ventilating duct, is connected below the oil return pipe
There is oil-immersed pump, flowing relay and lower butterfly valve are provided with the oil guide pipe that the oil-immersed pump is connected with fuel tank.
Further, it is provided with oil filter between the oil return pipe and oil-immersed pump.
Further, the fin side is connected by fixing muscle.
Further, it is each provided with a venting plug on the oil inlet pipe a and oil inlet pipe b.
The beneficial effects of the utility model are：
1st, the utility model strengthens circulation of the oil between fuel tank and radiator by installing oil-immersed pump additional using oil-immersed pump, makes
Oil obtains more preferable cooling effect.The fan of fin side plays air cooling effect to it, improves radiating efficiency, oil return pipe
Interior oil passes through flowing relay by oil strainer, oil-immersed pump, and the bottom of fuel tank is entered finally by lower butterfly valve,
Cold oil becomes deep fat and rises to fuel tank upper strata to the cooling of device body, and winding, iron core will be cooled down after so circulating.Deep fat is from main oil-feed
Pipe flows through to each fin radiating by oil inlet pipe a, oil inlet pipe b, due to dissipating between oil inlet pipe a, oil inlet pipe b and oil return pipe
Backing is forming V-shape structure, and air circulation is big, and it is to ramp that heat sheds, and top heat-dissipating space is big, does not interfere with
Part heat sink conduct heat away, good heat dissipation effect, while saving oily resource.
