Technical field
The present invention relates to plant equipment cooling field, a kind of liquid nitrogen vaporization that uses carries out cooling device specifically, can reduce rapidly temperature for the experimental facilities heating up.
Background technology
The temperature of component of machine raises can affect safe operation and the service life of plant equipment, and it is the ring in weakness out in the cold that component of machine is lowered the temperature.
In some scientific experiments, due to some experimental provisions heat up very fast, often need to carry out these equipment cooling, to guarantee to test normal operation.
The patent No. 201220229840.1 " use for laboratory cooling device ", the experimental facilities that this device can only cooling solid shape, and cooling velocity is slower, cool time is unadjustable, and this device is not suitable for the complicated or experimental provision faster that heats up of cooling structure.
The patent No. 201220124025.9 " use for laboratory Wind cooling device ", it is cooling that this device adopts fan to carry out experimental provision, but can only the lower experimental provision of cooling intensification, can not make it lower the temperature rapidly for some higher these devices of parts that heat up.
At present in the plant equipment in laboratory, water-cooled and air-cooled be to use comparatively general cooling device.General water-filled radiator has a water inlet and delivery port, and there are many water channels radiator inside, can take away unnecessary heat.Air-cooled conventionally by the mobile speed of fan quickening parts surrounding air, realize the effect of cooling.These two kinds of cooling means cooling rates are slow and temperature fall time is unadjustable, are not suitable for the experimental facilities that cooling programming rate is very fast and intensification is higher.
Summary of the invention
Object of the present invention solves existing practical problem exactly, designs a kind ofly can carry out cooling device to rapid intensification and the higher experimental facilities that heats up, and designs respectively three kinds of shower nozzles for the difference of component of machine structure, can change as required.This device convenient disassembly, time saving and energy saving, can regulate cooling rate.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of cooled with liquid nitrogen device, by adding thermal control heat engine structure and Pen Dan mechanism forms, described Pen Dan mechanism is made up of the liquid nitrogen vacuum flask sealing, air supply pipe and changeable type shower nozzle, one end of air supply pipe passes in liquid nitrogen vacuum flask, its other end is connected with changeable type shower nozzle, the described thermal control heat engine structure that adds is made up of wire, contact type voltage regulator and heating core, and heating core is arranged in liquid nitrogen vacuum flask, and is connected with contact type voltage regulator by wire.
On air supply pipe outer wall of the present invention, be arranged with insulating tube.
Heating core of the present invention is nickel chromium triangle heating core.
In liquid nitrogen vacuum flask of the present invention, be provided with the heating core bracket for supporting heating core.
Changeable type shower nozzle of the present invention is the one in spraying nozzle, straight pipe type shower nozzle or circular shower nozzle.
Cooled with liquid nitrogen device of the present invention is also provided with the bracing frame for supporting liquid nitrogen vacuum flask.
Air supply pipe of the present invention is copper pipe.
The invention has the beneficial effects as follows: this apparatus structure is simple convenient disassembly, handling safety.Design three kinds of shower nozzles and respectively the component of machine of different structure is carried out coolingly, can regulate the escaped quantity of nitrogen simultaneously, and then realize and control cooling velocity, be especially suitable for the very fast and higher laboratory equipment that heats up of programming rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, bracing frame, 2, liquid nitrogen, 3, liquid nitrogen vacuum flask, 4, bottle stopper, 5, pipe joint I, 6, air supply pipe, 7, insulating tube, 8, pipe joint II, 9, heating core bracket, 10, changeable type shower nozzle, 11, wire, 12, contact type voltage regulator, 13, binding post I, 14, binding post II, 15, bracing frame I, 16, binding post III, 17, heating core.
The specific embodiment
As shown in the figure, changeable type shower nozzle 10 is divided into three kinds, and the first is divergence expression spraying nozzle, is mainly to carry out cooling to the component of machine of structure opening.The second is straight pipe type shower nozzle, is mainly to carry out cooling to the limited component of machine of structure.The third is circular shower nozzle, is evenly drilled with ten apertures in the inner side of annulus, and this class shower nozzle carries out cooling mainly for axial workpiece, when work, axial workpiece is inserted in annulus.Three kinds of shower nozzles can be dismantled by pipe joint, change and use as required.
In liquid nitrogen vacuum flask, be loaded with liquid nitrogen, by heating core, liquid nitrogen heated, in the time that liquid nitrogen is warming up to-196 ℃, liquid nitrogen vaporization becomes nitrogen, and the nitrogen of low temperature is sprayed by shower nozzle by copper pipe, forms a cooling atmosphere.Control the caloric value of heating core by the voltage of regulation contact voltage regulator, and then realize the escaped quantity of controlling shower nozzle place nitrogen.The pressure regulation range of contact type voltage regulator is 0 ~ 220V, and the power of corresponding heating core is 0 ~ 300W.
Liquid nitrogen vacuum flask 3 is arranged on bracing frame 1, and bracing frame 1 is steel design, steady to guarantee liquid nitrogen vacuum flask 3.One end of wire 11 connects by binding post III 16 and heating core 17, and heating core 17 is inserted on the heating core bracket 9 in liquid nitrogen vacuum flask 3, installs to guarantee that heating core 17 is stable.The other end of wire 11 is connected with contact type voltage regulator 12 by binding post I 13, and contact type voltage regulator 12 is placed in bracing frame I 15, and bracing frame I 15 is steel design.Shower nozzle 10 links together by pipe joint II 8 and air supply pipe 6, and shower nozzle 10 is evenly overflowed nitrogen, to reach good cooling effect.Insulating tube 7 is enclosed within the outside of air supply pipe 6, to keep the temperature of nitrogen in air supply pipe 6 as far as possible constant.One end of air supply pipe 5 is inserted in bottle stopper 4 and is passed in liquid nitrogen vacuum flask 3.Bottle stopper 4 is elastomeric material, to guarantee sealing effectiveness.
In described liquid nitrogen vacuum flask 3, fill liquid nitrogen 2, in the binding post II 14 of contact type voltage regulator 12, connect 220V AC power.When work, open the switch of contact type voltage regulator 12, voltage by regulation contact voltage regulator 12 heats heating core 17, and in the time that liquid nitrogen 2 is warming up to-196 ℃, liquid nitrogen 2 is vaporized into nitrogen, the nitrogen of low temperature is sprayed by shower nozzle 10 by air supply pipe 6 made of copper, forms a cooling atmosphere.
According to the needs of component of machine structure to be cooled, can dismantle pipe joint II 8 and change three kinds of shower nozzles 10.
Control the power of heating core 17 by the size of regulation contact voltage regulator 12 voltages, and then control the nitrogen escaped quantity at shower nozzle 10 places, realize different cooling velocities.Vaporize when complete when liquid nitrogen 2, the bottle stopper 4 of can dismantling rejoins liquid nitrogen 2.
