Abstract
The utility model relates to a jetting-aspirating air heat collector. The absorber plate of the interior of the cavity body is split into a non-permeating section and a permeating section which is made of a plurality of net wires. The air abuts on the surface in the jetting method through a slit jetting nozzle and enters the non-permeating section to strengthen the heat conversion. In the back permeating section, the air uniformly penetrates through the permeable porous net layer and is aspirated out, and the heated and the aspirated overall processes are completed. Compared with the existing air heat collector, the utility model has obvious thermal efficiency improvement, and is widely applied to the situations of drying, air conditioner ventilation, heat supplying, etc.
Description
The utility model relates to a kind of solar energy air heat collector device, is applicable to occasions such as drying, air conditioner ventilation, heating.
General air collector can be divided into two classes substantially, and a class is a type air collector thoroughly, and another kind of is type air collector thoroughly.
The solar energy one thermal power transfer process of type air collector is to finish in the thin layer of absorber very thin surface thoroughly.The characteristics of this heat collector are simple in structure, but a little less than the heat-transfer intensity between air and the absorber plate, come augmentation of heat transfer, but owing to can increase resistance simultaneously even use the absorber plate of corrugated plating or ribbing, the energy consumption of blower fan also will increase, and therefore total Ji art Jing Ji Xiao Guo And is bad.As international " solar energy " magazine the 11st volume No.1.(1962) " Solar Energy " last document " analysis of solar air heater performance " (Performance Studies on Solar air heaters) of publishing.
The type air collector is that air is flowed between cover plate and porous stratum reticulare absorber thoroughly.Though its performance is better than type thoroughly, but because fluid is percolation and a mistake on whole heat-absorbent surface, the gas channel area is big, percolation speed is low, cause the heat transfer between further reinforcement absorber and the air to be restricted, as U.S. Pat, in 4054,124 " a kind of high-efficiency solar gathering system ".Be exactly like this.
Task of the present utility model is the deficiency at present air collector, for augmentation of heat transfer, provides a kind of novel jet one drawing-in type air collector, and it can further improve the thermal efficiency of heat collector.
Characteristics of the present utility model are that the cavity of air collector is made two parts, a preceding part be can not be thoroughly section, a back part is can be thoroughly section.Can not be thoroughly the starting point of section, allowing air enter in the mode of jet by the slot spout can not be thoroughly section.Purpose is that air is limited in the very thin fluid layer, improves flow velocity, forms wall jet to strengthen heat convection.And, utilize the deflector in full-blown jet layer and the second fen chamber at back segment, and make air more equably from porous stratum reticulare Chuan Guo And sucking-off that can be saturating, finish the heated overall process of air.
Accompanying drawing one is a structure principle chart of the present utility model
Below in conjunction with description of drawings concrete enforcement of the present utility model: the end face of heat collector is glass cover-plate (1), section (3) thoroughly that the absorber plate in the cavity is divided into section (2) thoroughly and which floor twine is made of.Air forms skim in the mode of jet along section surface thoroughly by slot spout (4) and cools off fluid layer; The jet layer longshore current is to progressive additive, and flow velocity also reduces gradually.When fluid layer enters can be thoroughly during section, just pass section (3) sucking-off thoroughly that the porous stratum reticulare is formed.The heat exchange unit of being made up of these two cavitys can be designed to the multistage jet one drawing-in type air collector of actual needs according to user's actual needs with the mode of Chuan Lian Huo And joint group one-tenth.Pass the mobile uniformity of section thoroughly in order to improve air.Be provided with deflector (5) in the chamber at second minute.Air flows into from import (7), from outlet (8) sucking-off.In order to reduce the conductive heat loss of heat collector, be provided with heat-insulation layer (6) in side and bottom.
According to above imagination, it is 800 * 400mm that She Ji And has made a daylighting area
2Jet one drawing-in type air collector.Heat collector is made up of two heat-absorbing chambers, and the daylighting area of each heat collector cavity is 400 * 400mm
2, bottom and periphery are all used the thick polystyrene foam plate heat-insulation and heat-preservation of 25mm.Heat collector cavity welded seal, the joining place between cover plate and heat collector are smeared with putty with rubber seal Chen Dian And and are obturaged.Jet segment evenly is coated with Berlin black, and section porous stratum reticulare is by five layers of overlapping making of aluminium matter expansion stretching nets that evenly is coated with Berlin black thoroughly.Glass cover-plate adopts the thick simple glass of 5mm.
Experiment showed, that the utility model can in the situation that does not increase air mass flow and manufacturing cost, improve the flow velocity that air skims over absorber. And is with jet and stride stream with augmentation of heat transfer. Thereby obviously improved the thermal efficiency of heat collector. At ((ti－t
a）／I〕＜0.025℃m
2In the scope of/W, the high double-layer cover plate of thermal efficiency ratio cost of the present utility model is the type air collector thoroughly, tallerly goes out about about 7%.
Claims (2)
1, a kind of solar energy air heat collector of forming by glass cover-plate and absorber, it is characterized in that absorber in the heat collector cavity be divided into section (2) thoroughly and by the multilayer stratum reticulare forms can be thoroughly section (3) ， And and air are that the mode abuts on surface with jet enters can not be thoroughly section.
2, air collector as claimed in claim 1 is characterized in that being provided with in the chamber at second minute deflector (5).
