Abstract
The invention discloses a dual-cavity solar air collector, which comprises a glass cover plate, a solar heat-absorption plate core, a border and a back plate, wherein an upper cavity is formed between the glass cover plate and the solar heat-absorption plate core; a flow-choking radiation fin is arranged in a lower cavity which is formed between the solar plate core and the back plate; the flow-choking radiation fin divides the lower cavity into a circuitous channel; an air inlet and an air outlet are respectively formed in both ends of the circuitous channel; and an exhaust fan is mounted on the air outlet. The dual-cavity solar air collector has the following technical beneficial effects that the flow-choking radiation fin is arranged in the lower cavity which is formed between the solar plate core and the back plate, the flow-choking radiation fin divides the lower cavity into a nonlinear circuitous channel, and both ends of the channel are respectively connected with the air inlet and the air outlet of the lower cavity, so that the air through the cavities can flow through the whole lower surface of the solar heat-absorption plate core; the flow-choking radiation fin is tightly connected with the solar heat-absorption plate core so as to facilitate the heat transfer between the flow-choking radiation fin and the solar heat-absorption plate core, the flow-choking radiation fin is beneficial to increasing a radiation area of the heat-absorption plate core so that the air in the lower cavity can fully exchange the heat; and thus, a heat absorption coating of the solar heat-absorption plate core is free of influences of dust and steam, and the temperature of the air outlet of the solar air collector is increased.
Description
Technical field
The present invention relates to a kind of device that utilizes solar absorber plate to add hot-air, be mainly used in middle low-temperature bake field and environment temperature and regulate 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 the 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 adhere to inevitably with 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 by cavity, heat exchange is insufficient, and has the circulation of air dead angle in the cavity fast for air, 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.
Summary of the invention
The purpose of this invention is to provide a kind of leaving air temp high, the air collector of long service life.
Technical scheme of the present invention 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 the solar absorber plate core, in the cavity choked flow fin is set under forming between solar panels core and backboard, the choked flow fin is separated 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 the 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 panels core and the employing of choked flow fin fit tightly mode and fix.
Upper plenum adopts closed structure.
The solar panels core is to be compound on copper coin base material or the aluminium sheet base material by heat-absorbing paint to be made.
The present invention has following technique effect, the choked flow fin is set between solar panels core and the backboard forms a lower cavity, the choked flow fin is separated into nonlinear circuitous channel with lower cavity, the two ends of passage link to each other 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 the 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.
