Description

Wall behind the optoelectronic integration heliogreenhouse
Technical field
The utility model relates to the trans-utilization and the wall thermal insulation technology of solar energy, particularly a kind of optoelectronic integration and have the heliogreenhouse of thermal isolation and heat storage performance after wall.
Background technology
In recent years, heliogreenhouse has obtained widely using, and particularly the northern area winter temperature is very low, can not carry out the plantation of outdoor vegetable and flowers, and therefore will develop the vegetables and the production of flowers and plants has great demand to the application of heliogreenhouse.Heliogreenhouse is to utilize solar radiant energy to improve temperature in the greenhouse, to satisfy the requirement of plant growth to temperature.But only rely on solar radiation northerly winter, can not satisfy the environment temperature requirement in greenhouse.We know that the back wall in greenhouse, thing gable and soil all are the carriers that the greenhouse absorbs, stores solar energy and the greenhouse is heated up, and the back wall has heat absorption, accumulation of heat, insulation and dispels the heat in the body of wall of one usually, and environment temperature in the greenhouse is played bigger effect.Usually; The glazed area that solar energy is gathered in the greenhouse is certain; Conventional technical scheme all is to strengthen heat absorption, accumulation of heat, insulation and the heat-sinking capability of back wall; For example: on December 14th, 2011; The Chinese patent document discloses " a kind of heliogreenhouse that the heat accumulation function is arranged ", and (notification number: utility model patent technology CN202068783U), this technology are that the geographical features according to the Beijing area have adopted warming plate, heat storing plate, preceding antifreeze dividing plate, special-shaped solid film pipe, vertical solid film pipe, false ceiling six new materials, new technologies to be combined into a kind of heliogreenhouse with insulation, heat accumulation function.The advantage of this technology is that the back wall has adopted heat storing plate, and certain heat accumulation function is arranged; Shortcoming is owing to changed the arc design of heliogreenhouse, causes daylighting area not enough, simultaneously in the insulation collection of also having blocked sunlight, so the greenhouse depends the solar irradiation shortage of heat that limited daylighting area absorbs alone, the amount of insulation, heat accumulation is also not enough.Also announced " a kind of heliogreenhouse is used the compound heat preservation body of wall " (patent announcement number: CN200961303) on 10. 17th, 2007 Chinese patent documentations; This technology is to be made up of inside and outside body of wall; Insert and put the thermal insulation layer therebetween, described inner, external wall body and function air-entrained concrete building block is built.Body of wall is thicker than outer body of wall in described, and middle thermal insulation thermal insulation board is the polyphenyl thermal insulation thermal insulation board.Utilize it can make that a kind of cost is low, the heliogreenhouse of good heat insulating.This technology is had large improvement, even shortcoming be lean on heat that the daylighting area in greenhouse absorbs all storages also be not enough.Above-mentioned technology therefore in the season of northern severe cold, can not guarantee the required temperature of normal growth of crop owing to there are not enough thermals source; If but be directly installed in the existing body of wall solar-electricity heater or the surface; Since can not accumulation of energy, obviously be irrational, in addition; The voltage of solar energy power generating is unsettled, can not be suitable for the common electrical calandria.In addition, clay is a kind of hydrous alumino silicates product, generates by containing the effect of feldspar rock through long-term weathering and geology in the earth's crust; Clay has that particle is thin, plasticity is strong, associativity is good; Thixotropy is excessive, and it is suitable to shrink, processing performances such as degree of fire resistance height.The inventor is unexpected to find that the clay of compacting has good heat storage performance, and not other slow heat release under the uniform temperature gradient.
