New program temperature drop with novel structure, convenient use, high work efficiency, can effectively resolve the liquid nitrogen consumption big, the size and shape of the sample is restrained and uneven cooling.
the solution is that, including liquid nitrogen container, liquid nitrogen container with horizontal heating wire, heating wire through the wires and placed in liquid nitrogen container of data acquisition and control device to connect, liquid nitrogen container inside part in outside of the infusion liquid nitrogen vessel nitrogen pipe, tube infusion nitrogen gas inlet on the upper heating wire and don't contact with them, the infusion position with the outlet of the nitrogen pipe insulation box, adiabatic division side on their cases and transfusion air outlet of the nitrogen pipe, corresponding to the fixed place with hydrocyclone infusion in nitrogen pipe the outlet in hydrocyclone, adiabatic thing fixed have put on the floor under the table in the oven, adiabatic temperature sensor is fixed side in the oven, the temperature sensor through wires connected to the data acquisition and control devices.
