Embodiment

[0038] A single-row solar / air energy evaporative heat collector with equal flow and positive pressure. The evaporator fins are made of Al alloy with a thickness of 0.2mm. The chromium atomic layer is strongly magnetically condensed on the surface of the Al alloy fin by physical methods. The heat-absorbing heating film has a compact structure, an absorption rate of 0.93-0.97, an emissivity of 0.07-0.11, and stable physical and chemical properties. The micron-level thickness has little effect on the heat transfer coefficient of the aluminum alloy fins, which can reduce the loss of the heat transfer coefficient of the fins while increasing the solar radiation absorption.

[0039] The transparent casing of the unit is made of toughened glass, which has outstanding performance in physical and chemical stability, and is suitable for long-term, fully-loaded units. Open uneven ventilation holes on the front tempered glass, the specific operation is sparse on the central inspection sid...

Abstract

The invention belongs to the technical field of evaporation heat collectors, and particularly relates to a flow-equalizing positive-pressure single-row solar / air energy evaporation heat collector. A transparent tempered glass cover plate is arranged at the upper portion of a shell. A tempered glass plate with uneven holes is arranged on the front face of the shell. A fan, a flow equalizing plate and a single-row evaporator coated with a chromium atom solar selective absorption coating are arranged in the shell. The flow equalizing plate is arranged between the fan and the single-row evaporator coated with the chromium atom solar selective absorption coating. The flow-equalizing positive-pressure single-row solar / air energy evaporation heat collector has the beneficial effects that 1, the total solar energy absorption amount on the surface of the evaporator is increased; 2, a proper fan arrangement form is selected, so that the shielding of the fan on solar radiation is reduced; and 3, the problem of low performance caused by non-uniform airflow distribution of the evaporator is solved.

Description

technical field [0001] The invention belongs to the technical field of evaporative heat collectors, in particular to a single-row solar energy / air energy evaporative heat collector with equal flow and positive pressure. Background technique [0002] Solar energy is an inexhaustible and widespread energy source. The use of solar energy makes up for the low COP of air source heat pumps in low temperature environments. It is a supplement to air energy at low temperatures. , the combination of solar energy and air energy has become a hot issue in the research of air source heat pumps, and the combination of the two is often transformed in the outdoor evaporator. Common solar / air energy evaporators include solar-assisted solar air energy evaporators, solar photovoltaic air energy evaporators, etc. The latter system has a large volume and is not suitable for high-rise residential buildings, while the former often has a low solar energy utilization rate, which increases the cost a...
