Embodiment Construction
[0028] The present invention will be described in further detail below according to the accompanying drawings.
[0029] As shown in the figure, the liquid nitrogen thermos is filled with liquid nitrogen, the electric heating core is fixed in the liquid nitrogen thermos, and the electric heating core is connected with the contact voltage regulator through wires. The oil supply pump is fixed on the oil tank, and is connected to the device to be lubricated through the oil supply copper pipe for lubrication. The amount of oil supply can be realized by controlling the rotation angle of the oil outlet valve. A plate radiator is installed on the oil return road, and the cooled lubricating oil is returned to normal temperature through the circulation of tap water in the plate radiator. The oil pump is connected to the oil outlet of the plate radiator through an oil return copper pipe, and the oil pump pumps the lubricating oil back into the oil tank to realize recycling.
