Description

Defrosting device of solar flat plate collector

Technical Field

The utility model relates to a solar flat plate collector field particularly, relates to a solar flat plate collector defroster.

Background

The flat-plate solar heat collector is a device for absorbing solar radiation energy and transferring heat to a working medium, and is a special heat exchanger, and the working medium in the heat collector exchanges heat with remote sun. The flat-plate solar heat collector consists of a heat absorption plate core, a shell, a transparent cover plate, a heat insulation material and related parts. After the circulation pipeline and the heat preservation water tank are additionally connected, the solar radiation heat can be absorbed, and the water temperature is increased.

The flat-plate solar collector is a basic component for low-temperature heat utilization of solar energy and is also a leading product in the world solar market. Flat plate type heat collectors have been widely used in various fields such as domestic water heating, swimming pool heating, industrial water heating, building heating and air conditioning. The water heater formed by flat-plate solar heat collector components is a flat-plate solar water heater. The flat-plate solar collector mainly comprises a flat-plate solar collector absorber plate, a flat-plate solar collector transparent cover plate, a flat-plate solar collector heat insulation layer, a flat-plate solar collector shell and the like.

When the humidity in the flat-plate solar collector is higher due to certain factors, sunlight penetrates through the glass and is irradiated to the heat absorber, the heat absorber rapidly heats up to drive the humid air in the collector to heat up, the hot humid air meets the relatively cold glass, fog-packed water vapor is easily formed on the inner surface wall of the glass, so that the projection of the sunlight and the performance of the collector are influenced, and the main factor of the generated fog is that the sealing performance of certain parts of the collector is insufficient, so that the external water vapor is easily introduced into the collector; the moisture discharging capacity of the heat collector is poor, so that moisture accumulated in the heat collector is difficult to discharge.

An effective solution to the problems in the related art has not been proposed yet.
