The invention relates to the field of hot water thermal insulating pipe structures. The thermal insulating pipe comprises an outer pipe and an inner pipe. The inner pipe is fixed on the center of the outer pipe through a fixing support. A polyurethane insulation coating is formed between the outer pipe and the inner pipe through polyurethane foaming. The outer surface of the inner pipe is provided with a solar heat absorption coating. The inner surface of the outer pipe is provided with an infrared reflection coating. The thermal insulating pipe can satisfy requirements of high-temperature heat conduction and long time heat conduction.
Description
Technical field
The present invention relates to hot water heat insulating pipe construction applications, between a kind of especially solar energy hot water tank, connect the insulating tube with hot water outlet.
Background technology
In winter, owing to the heat loss of water pipe even reduces by 10 DEG C, greatly waste the energy.In order to reduce from boiler next to the heat loss of the hot-water line of user, tube surface heat insulating cloth is wrapped up by people, and this method has the disadvantage that: install cumbersome, will be coated with heat insulating cloth temporarily；Owing to manually cladding makes there is bigger space between heat-insulation layer and pipeline outer wall, so the effect of insulation is not ideal enough, bigger energy is still had to leak；Leaking owing to there is energy, so safe not, particularly when heat insulating cloth breakage, it is easy to the security incidents such as scald or cold injury occur and shortens the service life of insulating tube, and the heat insulating cloth being exposed to outside also is difficult to stand low temperature and rainy invasion.
Solar heat reflection reticulate pattern insulating tube disclosed in Chinese patent 201320479875.5, it is bimetallic tube, and innermost layer is interior pipe, and outer wall of inner tube is coated with one layer of heat-reflecting layer, wraps up reticulated duct outside heat-reflecting layer.But this structure is due near apart between inner and outer pipes, and heat insulation effect is in long-time heat preservation situation, and effect is substantially not enough；Particularly high-temperature, long-time leading to are incubated the deficiency that seems under enthusiasm condition.
Summary of the invention
The goal of the invention of the present invention is: for above-mentioned technical problem, it is provided that a kind of insulating tube, meets high temperature and leads to the situation needs of logical heat hot, long-time.
Technical solution of the present invention is: a kind of insulating tube, including outer tube and interior pipe, said inner tube is fixed on outer tube hub by fixed support, polyurethane insulation coating is formed by polyurethane foam between described outer tube and interior pipe, said inner tube outer surface is provided with solar energy heat absorbing coating, and described outer pipe internal surface is provided with infrared reflection coating.
Needing exist for being appreciated that, polyurethane foam forms polyurethane insulation coating and has excellent heat insulation effect, concurrently forms wider heat-insulation layer, it is possible to meet the needs of long-time logical heat insulation.On the basis of the above, also add solar energy heat absorbing coating, solar energy heat absorbing coating can better absorb infrared ray, thus form a heat absorbing ring or perhaps heat build-up layer at inner tube outer surface, due to interior pipe direct contact heat water or hot solution, cause that its inner tube outer surface still has higher temperature, and the heat that solar energy heat absorbing coating can reduce interior pipe overflows.And intermediate urethane heat-insulation layer reduces heat diffusion further, outer pipe internal surface is provided with infrared reflection coating to the infrared reflection of polyurethane insulation coating, can reduce the diffusion of polyurethane insulation coating heat.Multi-layer heat preserving structure is so set, gradually reduces heat in interior pipe and externally spread, reach the effect of insulation.Compared to existing technology, heat insulation effect becomes apparent from, and meets high temperature and leads to the situation needs of logical heat hot, long-time.
Preferably, it is additionally provided with ceramic coating between described infrared reflection coating and interior pipe.Ceramic coating has the advantages that specific heat capacity is big, has good heat insulation effect to this its.
Preferably, described polyurethane insulation coating is provided with some through holes, and described through hole is parallel with interior tube hub axis.Through hole is set and can increase interlayer, optimize polyurethane heat-insulation Rotating fields further.
Preferably, said inner tube is metal bellows.Metal bellows provided herein is preferred embodiment.
The medicine have the advantages that
1, the present invention is made up of outer tube, infrared reflection coating, polyurethane insulation coating, solar energy heat absorbing coating and interior pipe, during use, hot water is at interior Bottomhole pressure, solar energy heat absorbing coating forms heat absorbing ring, in reducing, pipe externally heat radiation, plays thermal insulation function, and polyurethane insulation coating further functions as the effect of insulation, infrared reflection coating to the infrared reflection of polyurethane insulation coating, can reduce the diffusion of polyurethane insulation coating heat；In so, the energy of the hot water in pipe not easily leaks；Will not out form the security incident of scald (or cold injury) by Quick diffusing, it is possible to meet high temperature and lead to the situation needs of logical heat hot, long-time.
2, present configuration is reasonable, and heat insulation effect is obvious, and firm in structure, reliable in quality, also easily carrying and installation.
3, the present invention utilizes the energy loss that the medium (such as water, gas etc.) in interior pipe is only only small in course of conveying, thus having saved the energy, being conducive to environmental protection, and making insulating tube form the product of a molding, it is simple to promotion and application.
