Abstract
The utility model discloses a tubular heat insulation device with steady heat insulation effect, which comprises an outer aluminum foil tube and inner aluminum foil tube, wherein heat insulation materials are filled between the inner aluminum foil tube and the outer aluminum foil tube, heat conduction end covers are arranged on the two ends of the outer aluminum foil tube, heat conduction holes are arranged on the heat conduction end cover, and a support spring ring is arranged between the heat insulation materials and the inner surface of the outer aluminum foil tube. Compared with the prior art, the tubular heat insulation device with steady heat insulation effect has excellent heat stability and thermal shock resistance, can achieve use temperature of 800-1350DEG C, has three protection functions of heat insulation, heat dissipation and counter heat, and can greatly enhance heat insulation reliability.
Description
Technical field
The utility model relates to a kind of insulating tubular device, is applicable to the thermal insulation protection field of automobile pipeline, flexible axle.
Background technique
Under the situation of current various countries automotive industry competition ten minutes fierceness; The cycle that each automobile factory's vehicle updates is shorter and shorter, and in order effectively to utilize the space, car load is arranged also more and more compacter; Pipeline on the car, flexible axle etc. will pass through near the high-temperature part (like turbosupercharger) sometimes; If it is not effectively protected, just might cause scald, influence vehicle driving safety.With the flexible axle is example, and if it is too near from high-temperature part, the material melts of the crust of flexible axle and internal lining pipe distortion behind the long duration of action, and that cooling back flexible axle can occur is stuck, send out a wrinkle phenomenon makes the flexible axle inefficacy.The appearance of insulating tubular device has solved this problem, no longer lets Automobile Design teacher for how getting around the high-temperature part headache.But the insulating tubular device that uses at present is to adopt outer one deck aluminium foil and inner one deck asbestos paper to be locked at the heat insulation method on the flexible axle, and its shortcoming is following: (1) water-proof performance is low, and after being drenched by water, asbestos paper lost efficacy, and lost effect of heat insulation; (2) the no strong point in the aluminium foil, in transportation or assembly process, after aluminium foil was extruded, thermal conductivity increased, and effect of heat insulation reduces; (3) after the locking of aluminium foil two ends, air can't circulate, poor radiation.
Summary of the invention
The purpose of the utility model provides the stable insulating tubular device of a kind of effect of heat insulation.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is:
A kind of insulating tubular device comprises outer aluminium foil pipe, interior aluminium foil pipe, is filled with thermal-protective material between interior aluminium foil pipe and the outer aluminium foil pipe, and the two ends of outer aluminium foil pipe are provided with the heat conduction end cap.
The utility model adopts inside and outside aluminium foil pipe, and water-proof performance is good, has low heat conductivity, low heat capacity, and excellent heat insulation property and good chemical stability, anti-erosion, electrical insulating property is good, has elasticity and pliability preferably, is convenient to installation and processing.Aluminium foil also has certain reflecting action, and the portion of hot radiation can reflect back.
The heat conduction end cap is provided with thermal hole, in the defeated running process of car, possibly take away the part heat through air ventilation.
Be provided with the supported spring circle between the internal surface of thermal-protective material and outer aluminium foil pipe, inside and outside aluminium foil pipe joined in the process at transportation or device do not damaged by pressure, the while also can provide the space for air stream.
Compared with prior art; The utlity model has good thermostability, thermal shock resistance, serviceability temperature can reach: 800 ℃～1350 ℃; That its structure has is heat insulation, the triple protection effect of heat radiation and anti-heat, and the heat insulation reliability of the utility model is strengthened greatly.
Description of drawings
Fig. 1 is the generalized section of the utility model insulating tubular device.
Fig. 2 is the structural representation of heat conduction end cap.
Fig. 3 is an A place enlarged view among Fig. 1.
Among the figure, the outer aluminium foil pipe of 1-, aluminium foil pipe in the 2-, the 3-thermal-protective material, 4-heat conduction end cap, 5-supported spring circle, the 6-thermal hole, 7-is by protective.
Embodiment
Requiring the technological scheme of protection to do below in conjunction with accompanying drawing to the utility model specifies.
The described a kind of insulating tubular device of the utility model, as shown in Figure 1, comprise outer aluminium foil pipe 1, interior aluminium foil pipe 2, be filled with thermal-protective material 3 between interior aluminium foil pipe 2 and the outer aluminium foil pipe 1, the two ends of outer aluminium foil pipe 1 are provided with heat conduction end cap 4.
As shown in Figure 2, heat conduction end cap 4 is provided with thermal hole, and 8 thermal holes 6 are set usually.
Like Fig. 1, shown in 3, be provided with supported spring circle 5 between the internal surface of thermal-protective material 3 and outer aluminium foil pipe 1.
During actual the use, aluminium foil pipe 2 in by protective 7 outsides dress wraps thermal-protective material 3 again on interior aluminium foil pipe earlier, and thermal-protective material 3 skins support with supported spring circle 5, refill outer aluminium foil pipe 1 then, adopt two heat conduction end caps 4 to be fixed on by on the protective 7.
Claims (3)
