Abstract
The utility model discloses a double-wall spiral wave heat exchange tube for a heat exchanger. The tube comprises an inner tube and an outer tube that are spiral and provided with spiral blades. Six spiral blades are provided. Gaps are disposed inside the spiral blades, and between the inner tube and the outer tube. The two ends of the inner tube are provided with inner tube ports, and the two ends of the outer tube are provided with outer tube ports. Double-wall tube gaps are disposed between the inner tube ports and the outer tube ports. The size of the double-wall tube gaps ranges from 0.1 mm to 0.3 mm. By adopting the above-mentioned method, the tube can prevent two mediums from mixing in case of leakage in the inner tube of the heat exchanger to generate intersect pollution, fluorine system is used without potential dangers, and safety of system heat exchange is greatly improved.
Description
Technical field
The utility model relates to field of heat exchangers, particularly relates to a kind of heat exchanger double-walled helical corrugation heat exchanger tube.
Background technology
Heat exchanger is a kind of energy-saving equipment that between material, heat transmits of realizing between two or more fluid of different temperatures, to make heat pass to by higher fluid the fluid that temperature is lower, make fluid temperature (F.T.) reach flow process set quota, to meet the needs of process condition, also improve one of capital equipment of energy utilization rate simultaneously.
Prior art is single wall formula corrugated spiral heat-exchange tube for coaxial heat exchanger inner tube, as shown in Figure 1, when coaxial heat exchanger single wall inner tube occurs to reveal, participates in the two media anti-channeling of heat exchange, produces cross pollution, and the fluorine system of shell is caused to more serious destruction.Refrigerant enters use side, and oil, beverage, domestic water etc. are caused to severe contamination, for people's the security of the lives and property, has huge hidden danger.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of heat exchanger double-walled helical corrugation heat exchanger tube, can prevent the anti-channeling of two media when heat exchanger inner tube is revealed, produce cross pollution, guarantee using without hidden danger of fluorine system, greatly improved the security of system heat exchange.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of heat exchanger double-walled helical corrugation heat exchanger tube is provided, comprise inner and outer tubes, described inner and outer tubes are concentric, inner and outer tubes are helical form, and inner and outer tubes are provided with helical-blade, the quantity of described helical-blade is 6, described helical-blade inside, between inner and outer tubes, be also provided with cavity, the two ends of described inner tube arrange inner tube port, the two ends of outer tube arrange outer tube port, between described inner tube port and outer tube port, double-wall pipe gap is set, the size range in described double-wall pipe gap is 0.1mm-0.3mm.
Preferably, the long 20mm-35mm of length of the Length Ratio outer tube port of described inner tube port.
Preferably, the material of described inner and outer tubes is copper.
The beneficial effects of the utility model are: the utility model can effectively prevent that inner tube from leaking the medium anti-channeling causing, and produce cross pollution, guarantee using without hidden danger of fluorine system, greatly improve the security of heat exchange.

The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 2 and Fig. 3, the utility model embodiment comprises:
A kind of heat exchanger double-walled helical corrugation heat exchanger tube, comprise inner tube 2 and outer tube 1, described inner tube 2 and outer tube 1 are concentric, inner tube 2 and outer tube 1 are helical form, and inner tube 2 and outer tube 1 are provided with helical-blade 3, the quantity of described helical-blade 3 is 6, described helical-blade 3 inside, between inner tube 2 and outer tube 1, be also provided with cavity 4, the two ends of described inner tube 2 arrange inner tube port 6, the two ends of outer tube 1 arrange outer tube port 5, between described inner tube port 6 and outer tube port 5, double-wall pipe gap 7 is set, the size range in described double-wall pipe gap 7 is 0.1mm-0.3mm, when system occurs to leak, its leakage fluid all will be discharged to the outside of heat exchanger effectively from the double-wall pipe gap 7 of 0.1mm-0.3mm, thereby prevent from heat-exchange system to damage or damage.
Preferably, the long 20mm-35mm of length of the Length Ratio outer tube port 5 of described inner tube port 6, is in order to add man-hour at the draw like this, and the gap between tube wall is full evenly.
Preferably, the material of described inner tube 2 and outer tube 1 is copper, and copper has good thermal conductivity, has improved heat exchange efficiency.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
