Description
Technical field
The utility model relates to solar energy heat utilization field, specifically, has related to a kind of solar energy air heat collector.
Background technology
Solar energy air heat collector is a kind of solar heat collector take air as heating agent, is widely used in the fields such as solar heating, ventilation, dehumidifying.The most frequently used version is the plate type solar air collector, compare with vacuum tube solar heating element, it have simple in structure, seal request is low, do not need the advantages such as antifreeze, but the shortcoming such as it is low simultaneously also to exist collecting efficiency, and heat loss is large.How further to improve the collecting efficiency of plate type solar air collector, be the target that the scientific research personnel pursues always.
The plate type solar air collector mainly is comprised of single or multiple lift glass cover-plate, absorber plate, heat-insulation layer and protecting sheathing.Its operation principle is: after solar radiant energy sees through glass cover-plate, the absorber plate that its energy is coated with selective coating absorbs, and energy transform into heat energy, then passes to working medium, the temperature of working medium is raise, and flowing heat delivery to the place that needs with heat by working medium.Because the runner of air from import to outlet is the place of resistance minimum, thus the very difficult each point that flows through equably on absorber plate of air, cause heat exchange uneven, the collecting efficiency of heat collector is not high.
For the problems referred to above of plate type solar air collector, existing a lot of corrective measures.Invention as patent publication No. CN200986333, it is characterized in that absorber plate is divided into two of above and belows heat tunnel with heat collector cavity, increased air and added hot path in heat collector, adopted simultaneously the waveform heat collection chip to have increased heating surface (area) (HS and strengthen the disturbance of air.The and for example invention of patent publication No. CN101178260A, it is characterized in that adopting airtight heating air duct between absorber plate and insulation base plate, be provided with the thermal-collecting tube of vacuum heat-preserving above heating air duct, make air do secondary cycle between the thermal-collecting tube of heating air duct and vacuum heat-preserving and flow, in order to obtain better heat exchange.
Although the enforcement of above-mentioned patent has certain effect to the hot property that improves solar energy air heat collector, the amplitude that improves is less.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thereby a kind of design science, collecting efficiency is high, practical, use cost is low solar energy air heat collector are provided.
to achieve these goals, the technical scheme that the utility model adopts is: a kind of solar energy air heat collector, it comprises absorber plate, insulation shell and transparent cover plate, described transparent cover plate and described insulation shell consist of air cavity, described absorber plate is arranged in described air cavity and with described air cavity and is divided into upper gas chamber and lower air chamber, offer air inlet and air outlet on described insulation shell, described air inlet is communicated with described upper gas chamber and described lower air chamber, described air outlet is communicated with described upper gas chamber and described lower air chamber, described absorber plate is to be sinusoidal wave corrugated heat absorption thin plate, be distributed with bubbling and pit on described absorber plate.
Based on above-mentioned, described bubbling and described pit are embarked on journey and are crisscross arranged.
Based on above-mentioned, a described absorber plate side on the sunny side is coated with selective heat absorbing coating.
The relative prior art of the utility model has substantive distinguishing features and progress, and specifically, the utility model adopts sinusoidal wave corrugated absorber plate not only can increase endotherm area, can also produce Multi reflection and absorption; The bubbling that increases on absorber plate and pit have destroyed the boundary layer of Air Flow, thereby have increased the convection transfer rate of absorber plate and air, and combination has both improved the hot property of solar energy air heat collector to greatest extent.
