Description
Technical field
The utility model relates to a kind of solar adsorption-type refrigerating system, specifically, relates to a kind of metal fin tubular type based on CPC concentrator absorption heat collection bed, belongs to solar energy utilization technique field.
Background technology
Solar adsorption-type refrigerating has that structure is simple, movement-less part, environmentally friendly, effectively can utilize the advantages such as low-grade heat source.From the angle of comprehensive utilization of energy and environmental protection, absorption type refrigerating is a kind of refrigeration modes having much potentiality, and solar powered adsorption refrigeration technology meets the requirement of sustainable development completely, thus receives extensive attention in modern refrigerant field.
Adsorbent bed in solar adsorption-type refrigerating system is thermal-arrest and adsorption/desorption function usually, usually also claims absorption heat collection bed.Common adsorbent bed has flat, electron tubes type and metal pipe type.Although can fill more adsorbent flat, its sealing, anti-pressure ability is also more weak, is unfavorable for the absorption type system that vacuum level requirements is higher; Although electron tubes type thermal-arrest and heat-insulating property are well, adsorbent loading is few, cooling stage cooling difficulty, so both influential system refrigerating capacitys, again the carrying out of the adsorption process of unfavorable system; Although metal pipe type effectively can improve the loading of adsorbent, and sealing, compressive property is good, but it is comparatively large that weak point is exactly the thermal capacitance of such adsorbent bed self, can cause a large amount of system heat losses, have a strong impact on the performance of system in the heating and cooling stage own.Its Patent (ZL 2,011 2 0203751.5) is the optimization form of metal pipe type adsorbent bed, and this patent is set up fin by employing in metal tube inside and increased heat transfer area, enhanced heat exchange, reaches certain effect of optimization; But this kind of adsorbent bed is low to solar radiation energy utilization rate, reason only has metal tube the first half to accept solar radiation, and the latter half only obtains heat by metal pipe-wall heat conduction, adsorbent bed desorption efficiency is caused to reduce, and in absorption phase, because heat-insulating material is attached on metal pipe-wall, the heat of adsorption of adsorbent can not be discharged in time, have impact on refrigeration.
Therefore, improve the solar energy utilization ratio of adsorbent bed, the transmission of strengthening heat, reduces the deficiency of the aspects such as the heat transfer obstacle in adsorption/desorption each stage, particularly important for the refrigerating efficiency improving solar adsorption-type refrigerating system.
Summary of the invention
The utility model is intended to overcome in existing solar adsorption-type refrigerating system the deficiency of adsorbing existing for heat collection bed, propose a kind of metal fin tubular type based on CPC concentrator absorption heat collection bed, this absorption heat collection bed can increase the heating surface area of metal fin pipe adsorbent bed largely, simultaneously because CPC concentrator is to the spotlight effect of solar radiation, metal fin pipe internal-external temperature difference is increased, be conducive to the transmission of hot-fluid, the overall programming rate of adsorbent bed and efficiency are improved; In absorption phase owing to not having the attachment of heat-insulating material, heat of adsorption is more prone to discharge; , feature that good airproof performance, crushing resistance strong large with packing space again.
The utility model completes by the following technical programs: a kind of absorption of the metal fin tubular type based on CPC concentrator heat collection bed, primarily of CPC spotlight camber and fin adsorption tube composition.It is characterized in that: fin adsorption tube is arranged at the focus place of CPC spotlight camber, form CPC optically focused heating fins adsorption tube unit, multiple such unit parallel arranged, each fin adsorption tube two ends are by confluxing tubes connection and form the overall absorption heat collection bed of a sealing, bottom it and side infill heat-insulating material, top adds glass cover-plate.
Above-mentioned CPC concentrator can be symmetrical expression or asymmetric investigation on several focus reflectors, and its reflecting surface can be glass-mirror or metal mirror.
Above-mentioned fin adsorption tube can use duralumin or copper to adopt integrated drawing technology to cast and form; Outer tube wall can carry out alumilite process or magnetron sputtering technique process, and being formed can the oxide-film of efficient absorption heat energy; Heat-insulating material can adopt polyurethane, asbestos or glass fibre; Glass cover-plate can adopt the ultra-clear glasses or safety glass that transmissivity is high.
Operation principle of the present utility model is: sunshine incides on absorption heat collection bed lighting surface, through the sunshine of glass cover-plate, a part shines directly into the upper surface of fin adsorption tube and is directly absorbed by fin adsorption tube, remainder light is irradiated on CPC spotlight camber, reflexes to after fin adsorption tube also absorbed by fin adsorption tube through CPC spotlight camber.The most sunshines incided on whole absorption heat collection bed lighting surface are all absorbed by absorption heat collection bed after direct irradiation or reflection, the solar radiant energy of absorption received by heat collection bed will be multiplied, and increase multiple and be decided by the multiple of designed CPC concentrator.
The beneficial effects of the utility model are: owing to adding CPC concentrator, add effective daylighting area, make whole fin tube type adsorb the effective that heat is multiplied of heat collection bed, improve solar energy utilization ratio; Due to the reflex of CPC concentrator, the Lower Half of finned adsorption tube also obtains illumination, and make being heated of whole adsorption tube more even, be more conducive to the heat trnasfer adsorbing heat collection bed, adsorbent desorption rate is faster; Greenhouse effects are defined between glass cover-plate and CPC reflecting surface, contribute to temperature increase and the maintenance of adsorbent bed heating period, and adsorb on heat collection bed because heat-insulating material is not attached directly to, the heat of adsorption of absorption phase can be discharged in time, thus improve desorb and the rate of adsorption of adsorbent bed, improve the refrigerating efficiency of whole adsorption refrigeration system.
