The beneficial effects of the present invention are: by spraying one layer of insulation spray painting in snakelike tube outer surface, so as to perfect
The surface of coiled pipe is fitted in, and reduces the presence of insulating film, without worrying bubble occur between insulating layer and cooling tube
The problem of, and by insulation spray painting, compared to insulating film to heat to block ability smaller, it is easier to carry out it is thermally conductive, it is cooling
Effect is stronger compared with the existing technology, whole more aesthetically pleasing, and by way of spraying, compared to artificial patch insulating film
It says, consumption is artificial less, more time saving and energy saving.By the way that coiled pipe cooling tube is placed in packaging bag, progress vacuumize process,
Extraneous air pressure at this time can be by the surface for being pressed in coiled pipe of heat conductive silica gel tightly, to effectively prevent from storing for a long time
During, the problem of heat conductive silica gel scatters.
Specific embodiment
The production technology of spiral coil cooling tube, comprising the following steps:
Step 1, prepare straight tube, insulation spray painting, heat conductive silica gel, packaging bag；
Step 2, coiled pipe is made in straight tube；
Step 3, in the obtained snakelike tube outer surface spray insulation spray painting of step 2；
Step 4, after to the spray painting of coiled pipe spray insulation, then in the snakelike tube outer surface heat conductive silica gel is sticked；
Step 5, the coiled pipe that heat conductive silica gel finishes will be attached in step 4 to be packed into packaging bag；
Step 6, the packaging bag for enclosing coiled pipe is vacuumized, is then sealed.
By spraying one layer of insulation spray painting in snakelike tube outer surface, to replace insulating film, insulation spray painting can be complete
The surface for fitting in coiled pipe of beauty is painted by insulation, compared to insulating film to heat to block ability smaller, it is easier to
Carry out thermally conductive, cooling effect is stronger compared with the existing technology, and it is whole more aesthetically pleasing, and by way of spraying, compared to people
Work is pasted for insulating film, and consumption is artificial less, more time saving and energy saving.
By the way that coiled pipe cooling tube to be placed in packaging bag, vacuumize process is then carried out, at this time extraneous air pressure meeting
Heat conductive silica gel is pressed in the surface of coiled pipe, thus effectively prevent during storing for a long time, what heat conductive silica gel scattered
Problem.
It is further improved, in step 3, before the spray painting of snakelike tube outer surface spray insulation, first in snakelike tube outer surface electricity
It swims upper one layer of insulating materials, then carries out the process of spray insulation spray painting again.By electrophoresis, to make to be attached to outside coiled pipe
The insulating materials on surface is to be deposited on snakelike tube outer surface, is difficult to fall off, if insulation spray painting be painted on it is snakelike
Tube outer surface is easy the phenomenon that removing during long-time use since snakelike tube outer surface is relatively smooth, and
If first one layer of insulating materials on snakelike tube outer surface electrophoresis, then one layer of insulation spray painting is sprayed, at this point, insulation spray painting is not
It is easy to produce removing, and by two sides insulating materials, insulation performance can be made stronger, and safety coefficient is higher, when outermost
Side insulation spray painting removing when, there are also the insulating materials of internal layer to continue to play insulating effect, thus effectively prevent battery because with
Snakelike tube outer surface directly contacts, so as to cause electric leakage phenomena such as.
In step 4, after snakelike tube outer surface sticks heat conductive silica gel, need to detect whether heat conductive silica gel is adjacent to, because
The step of pasting heat conductive silica gel is mostly by manually carrying out, it may appear that viscous illusive phenomenon.
The step 2 includes:
A. it water-filling and pressurizes into straight tube；
B. it is bent using straight tube of the bending machine to water-filling and pressurization, straight tube is made to be bent to the coiled pipe of specific shape
Component, in the process, the water-filling and the step of being pressurizeed carries out always into straight tube, by the hydraulic pressure in straight tube, from
And guarantee phenomena such as straight tube is not in flattening during bending；
C. shape as needed will obtain that more snakelike tube assemblies are concatenated two-by-two to be welded in together in step b, thus shape
At coiled pipe；
D. air-leakage test is carried out to the coiled pipe after the completion of welding in step c, the air-leakage test is preferably to snake
It water-filling and is forced into 0.4Mpa in shape pipe and continues 2 minutes.
It is further improved, in a step, to water-filling in straight tube and before pressurizeing, stress test sampling observation first is carried out to straight tube,
Detect the intensity of straight tube.
It is further improved, in a step, to water-filling in straight tube and before pressurizeing, first straight tube outer surface is carried out at polishing
Reason, and straight tube surface is detected with the presence or absence of flaw.
It is further improved, in b step, pre-bending processing is first carried out before being bent using bending machine to straight tube, by pre-
Bend pipe is carried out again after curved, to keep production process safer.
It is further improved, in step c, more snakelike tube assemblies is connected before welding two-by-two, needed to snakelike tube assembly
End carries out fine cut and goes flash removed to specified specification, is then processed by shot blasting to coiled pipe module outer surface, detects later
The quality of snakelike tube assembly can just be welded after qualified, so as to be not in inferior goods so that final product quality is more preferable.
Certainly, the step of coiled pipe is made may be directly curved using straight tube progress of the bending machine to water-filling and pressurization
Folding, so that coiled pipe is made, but the probability that defective products occurs in the obtained coiled pipe of this method is higher.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all in the present invention
Inventive concept under, using equivalent structure transformation made by present specification, be applied directly or indirectly in other phases
The technical field of pass is included in scope of patent protection of the invention.
