Description
Technical field
The invention belongs to cooler field, be specifically related to a kind of negative pressure liquid nitrogen subcooler device.
Background technology
Subcooler device uses widely in workshop, domestic, the field such as automobile-used, conventional subcooler needs to utilize compressor or electric energy to provide power in process of refrigerastion, in large-scale cooling procedure and inapplicable, during the use of tradition liquid nitrogen subcooler, often it is quenched because of tube contacts liquid nitrogen to be cooled, causes pipeline breaking or pipeline contents generation Character change.
Summary of the invention
For solving the problems referred to above, the invention discloses a kind of negative pressure liquid nitrogen subcooler device, to be used for solving to waste the energy and the problem of pipeline quenching.
A kind of negative pressure liquid nitrogen subcooler device, including liquid nitrogen container, one-level cooler bin, two grades of cooler bins, described liquid nitrogen container top arranges cooling tube, described cooling tube passes one-level cooler bin, it is connected with two grades of cooler bins, inside described one-level cooler bin and two grades of cooler bins, materail tube is set, described one-level cooler bin lower right side arranges materail tube outlet, described two grades of cooler bin upper left-hand arrange nitrogen collecting pipe, two grades of cooler bin right upper portion arrange materail tube import, and described materail tube is snakelike to be arranged at inside one-level cooler bin and two grades of cooler bins.
As a modification of the present invention, described cooling tube arranges pressure-control valve.
As a modification of the present invention, described cooling tube is serpentine-like to be arranged in one-level cooler bin.
As a modification of the present invention, described materail tube diameter is less than cooling tube.
The invention has the beneficial effects as follows:
A kind of negative pressure liquid nitrogen subcooler device of the present invention, materail tube first passes around two grades of cooler bins, and the nitrogen relatively low with temperature contacts, tentatively cool down, enter back into one-level cooler bin, carry out heat transmission with the nitrogen of blood pressure lowering gasification, cool down further, it is prevented effectively from materail tube temperature decrease and causes the problems such as pipeline breaking material deterioration, liquid nitrogen container pressure is big simultaneously, makes two grades of cooler bins form negative pressure, the nitrogen active transmission that temperature is relatively low, the operation of supercharging, more efficient energy-saving are saved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Reference numerals list:
1. liquid nitrogen container, 2. one-level cooler bin, 3. two grades of cooler bins, 4. cooling tube, 5. materail tube, 6. materail tube outlet, 7. nitrogen collecting pipe, 8. materail tube import, 9. pressure-control valve.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with the present invention, it should be understood that following detailed description of the invention is merely to illustrate the present invention rather than limits the scope of the present invention.It should be noted that the word "front", "rear" used in describing below, "left", "right", "up" and "down" refer to the direction in accompanying drawing, word " interior " and " outward " refer respectively to the direction towards or away from particular elements geometric center.
nullAs shown in the figure，A kind of negative pressure liquid nitrogen subcooler device，Including liquid nitrogen container 1、One-level cooler bin 2、Two grades of cooler bins 3，Described liquid nitrogen container 1 top arranges cooling tube 4，Described cooling tube 4 is through one-level cooler bin 2，It is connected with two grades of cooler bins 3，Nitrogen pressure in cooling tube 4 is more than two grades of cooler bins 3，Described one-level cooler bin 2 and two grades of cooler bin 3 inside arrange materail tube 5，Described one-level cooler bin 2 lower right side arranges materail tube outlet 6，Described two grades of cooler bin 3 upper left-hand arrange nitrogen collecting pipe 7，Two grades of cooler bin 3 right upper portion arrange materail tube import 8，Material in materail tube 5 is contrary with the liquid nitrogen direction of motion in cooling tube 5 and two grades of cooler bins 3，It is more conducive to material gradually cool down，And ensure that making full use of of liquid nitrogen，Described materail tube 5 is snakelike is arranged at one-level cooler bin 2 and two grades of cooler bins 3 inside，Extend the time of materail tube 5 cooling，Enhance the effect of cooling.
As shown in the figure, arranging pressure-control valve 9 on described cooling tube 4, the pressure in liquid nitrogen container 1, more than the pressure in cooling tube 4, arranges pressure-control valve 9 and can discharge liquid nitrogen regularly, ensure that liquid nitrogen container 1 and the pressure reduction in cooling tube 4, it is ensured that the subnormal ambient of two grades of cooler bins 3 simultaneously.
It is arranged in one-level cooler bin 2 as it can be seen, described cooling tube 4 is serpentine-like, increases cooling area, strengthen the supercool effect in one-level cooler bin 2.
As it can be seen, described materail tube 5 diameter is less than cooling tube 4, cooling tube 4 can accommodate more nitrogen carrying out gasification heat absorption, increases supercool effect, makes materail tube 5 lower the temperature more thorough.
As shown in the figure, for ensureing the efficient energy-saving of whole supercooling apparatus, the outer layer of cooling tube 4, one-level cooler bin 2 and two grades of cooler bins 3 arranges heat-insulation layer, and cooling tube 4 and one-level cooler bin 2 and materail tube 5 and one-level cooler bin 2 and two grades of cooler bins 3 position that is connected arranges sealing ring.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, also includes the technical scheme being made up of above technical characteristic combination in any.
