Abstract
The utility model discloses a double-cavity solar air heat collector, which comprises a glass cover plate (1), a solar heat absorption plate core (2), a frame (4) and a back plate (5) and is characterized in that an upper cavity (9) is formed between the glass cover plate (1) and the solar heat absorption plate core (2); choke radiating fins (3) are arranged in a lower cavity (10) formed between the solar heat absorption plate core (2) and the back plate (5) and divides the lower cavity (10) into a periphrastic passage; an air inlet (6) and an air outlet (7) are respectively formed in two ends of the periphrastic passage; and an exhaust fan (8) is arranged at the exhaust outlet (7). The double-cavity solar air heat collector has the benefits as follows: the radiating area of the solar heat absorption plate core is enlarged; the reduction of influence on the heat absorption coating of the solar heat absorption plate core caused by dust and steam is facilitated; and the temperature of the air outlet of the air heat collector is increased.
Description
Technical field
The utility model relates to a kind of device that utilizes solar absorber plate to add hot-air, is mainly used in middle low-temperature bake field and environment temperature and regulates the field.
Background technology
Solar energy air heat collector mainly is comprised of solar absorber plate, glass cover-plate, frame, backboard at present, it is characterized in that, whole air collector inside only has cavity between glass cover-plate and absorber plate, the absorber plate another side directly and backboard fit tightly, air enters cavity by air inlet and discharges by exhaust outlet.This kind pattern has following deficiency: when air is compounded with the one side of heat-absorbing paint by absorber plate, airborne dust and steam inevitably adhere to heat absorbing coating on form schmutzband, reduce the absorptivity of heat absorbing coating; Hot and humid environment shortens the life-span of solar absorber plate; Cavity does not have the choked flow heat abstractor, and air is fast by cavity, and heat exchange is insufficient, and has the circulation of air dead angle in cavity, and the formation temperature field reduces the anti-solarization ability of absorber plate; Whole absorber plate heat radiation is inhomogeneous, causes air collector air outlet temperature low.
The utility model content
It is high that the purpose of this utility model is to provide a kind of leaving air temp, the air collector of long service life.
The technical solution of the utility model is, a kind of pair of cavity solar energy air heat collector, comprise glass cover-plate, solar absorber plate core, frame, backboard, form upper plenum between glass cover-plate and solar absorber plate core, in the lower cavity that forms, the choked flow fin is set between solar absorber plate core and backboard, the choked flow fin is divided into circuitous channel with lower cavity, be respectively equipped with air inlet and exhaust outlet at the two ends of circuitous channel, at exhaust outlet, ventilating fan be housed.
Distance between the upper plenum upper and lower surfaces is between 15mm to 35mm.
The choked flow fin is made by the good aluminium plate of heat conductivility, copper coin material or zinc-plated cold-reduced sheet, and solar absorber plate core and the employing of choked flow fin fit tightly mode and fix.
Upper plenum adopts closed structure.
The solar absorber plate core is to be compound on copper coin base material or aluminium sheet base material by heat-absorbing paint to be made.
The utlity model has following technique effect, the choked flow fin is set between solar absorber plate core and backboard forms a lower cavity, the choked flow fin is separated into nonlinear circuitous channel with lower cavity, the two ends of passage are connected with exhaust outlet respectively at the air inlet at lower cavity two ends, make by the whole lower surface of solar absorber plate core of flowing through of the air in the chamber; Choked flow fin and solar absorber plate core are combined closely and are conducive between the two heat transmission, and the choked flow fin is conducive to increase the area of dissipation of heat-absorbing plate core, make the air in cavity of resorption obtain sufficient heat exchange; Be conducive to reduce the impact that solar absorber plate wicking hot coating is avoided dust and steam, improve air collector air outlet temperature.
