Description
Technical field
The present invention relates to collection of energy and conversion, belongs to textile fiber technology field, is changed more particularly to a kind of energy
The preparation method of fiber.
Background technology
How rationally energy problem is always topic more popular for a long time, vigorously advocated instantly in energy conservation and environmental protection,
Become one of most critical issue using the energy.At present, energy conservation and environmental protection is only to be controlled when using the energy, by high efficiency of energy
Utilization so that limited energy obtains more permanent application, but not solving the problems, such as energy waste fundamentally.By the end of
At present, any machinery of mankind's design, in the process of running all with the loss of energy, the heat that when mechanical movement distributes is not only
Have an impact to the normal operation of most of machines, and scatter and disappear and can not recycle in atmosphere, in many fields, because fever is damaged
The energy of mistake accounts for very big proportion.For example, the heavy-duty machines in factory in process of production can be highly exothermic, it has to using taking
Many cooling measures, otherwise can run machine and cause tremendous influence, but can consume huge energy again in temperature-fall period；It is daily
The TV used in life, notebook, mobile phone etc., can continue heat release when in use, not only can the battery of the mechanical, electrical brain of opponent cause
Injury even sets off an explosion, and a kind of invisible energy loss.Therefore, the heat number beyond count being lost to daily in air,
But can not be collected；For this reason, being developed largely has the function of the device of collection of energy.
One or more of energy are converted into other one or more of energy by energy collecting device using the characteristics of its own
Amount, for example, by thermal energy, luminous energy, wind energy etc. be converted into it is other we with greater need for energy.And general heat collection device be
Around machine plus sheet metal, using machine operation when unnecessary heat sheet metal, then other materials are carried out by sheet metal
Insulation or heating, dispersed heat is recycled.
Such as Chinese utility model patent (application publication number：CN200940966Y, applies for publication date：2007-8-29), it is open
A kind of afterheat collector of injection moulding machine.Describe a kind of barrel heating sections waste heat that can fully recycle existing injection molding machine
Device.The afterheat collector of injection moulding machine is made of sheet metal, and the surrounding in barrel heating sections is configured around ground, remaining easy to collect
Heat, keeps the temperature the bringing-up section of injection molding machine with the sheet metal after heating, to make full use of the waste heat of injection molding machine.The collection device
It is simple in structure, make and install very convenient, of low cost, but application range is extremely limited, being only used for injection molding machine etc. has it
He partly needs the machine heated.Heat can not be effectively recycled for most of machine.
In addition, have many methods for collection of energy and conversion, and e.g., Chinese invention patent (application publication number：
CN103401474A, applies for publication date：2013-11-20) disclose a kind of magnetic hot systems.By the way that the thermal energy conduction of collection is given
Magnetic heat engine group, can convert heat energy into mechanical energy.This magnetic hot systems are suitable for middle low-temperature space and can mass produce, but
It is that this magnetic thermal device is too cumbersome, it is multiple possesses heat collection device, thermal energy transmitting device, magnetic heat engine group, line shaft etc.
Part, a collection of energy conversion equipment is assembled into using many mechanical organs, and does not meet the original intention for collecting energy, and is transported
Row is cumbersome, does not reach energy-saving and environment-friendly requirement, can also scatter and disappear energy while energy is collected.
Present many new flexible energy-collecting devices make that collection energy range is more extensive, and application is more changeable.It can not only utilize
The waste heat that machinery produces, while energy can also be stored under the temperature difference of human body.Such as Chinese invention patent (application publication number：
CN104883095A, applies for publication date：2015-9-2) disclose a kind of heat collection device of wearable device.Describe one kind
Produced electricity with the temperature difference away from skin surface using contact, powered to wearing.This method is simple and convenient, make people in daily wear the clothes just
Thermal energy can rationally be utilized.But wearable device made of this method need to use additional power source, although rationally utilizing heat source, its
The consumption energy itself, while the wearable device described in this method has excessive device, it is subject to a definite limitation in application.Finally
Wearable device described in this method need to be affixed on skin as far as possible, if itself and skin attachement, to its technological requirement height, it is necessary to flexible, breathable
All many factors consider；If it will not substantially reduced with skin attachement, its thermal energy collecting efficiency.
In conclusion there are device is cumbersome, application range is relatively narrow and cannot fundamentally solve to save for existing energy-collecting device
Can be environmentally friendly the problems such as.
