DESCRIPTION

A Flat Plate Collector is a heat exchanger that converts the radiant solar energy from the sun into heat energy using the well known greenhouse effect. ... These copper pipes are bonded, soldered or brazed directly to the absorber plate to ensure maximum surface contact and heat transfer.

Flat plate collectors consist of copper pipes running through a dark flat-plate absorber of solar energy that is covered in glass to reduce heat loss. Fluid is circulated through tubes to transfer heat from the absorber to an insulated water tank.

FEATURES

• Absorb direct, diffuse and reflected components o solar radiation,

• They are fixed in slant and orientation, and thus, there is no need for tracking the Sun,

• They are easy to make. ...

• Have comparatively low maintenance cost and Long lie, and.

• Operate at relatively high efficiency.

Solar Flat Plate Collector on Roof

A solar flat plate collector typically consists of a large heat absorbing plate, usually a large sheet of copper or aluminium as they are both good conductors of heat, which is painted or chemically etched black to absorb as much solar radiation as possible for maximum efficiency.

This blackened heat absorbing surface has several parallel copper pipes or tubes called risers, running length ways across the plate which contain the heat transfer fluid, typically water.

These copper pipes are bonded, soldered or brazed directly to the absorber plate to ensure maximum surface contact and heat transfer. Sunlight heats the absorbing surface which increases in temperature. As the plate gets hotter this heat is conducted through the risers and absorbed by the fluid flowing inside the copper pipes which is then used by the household.

The pipes and absorber plate are enclosed in an insulated metal or wooden box with a sheet of glazing material, either glass or plastic on the front to protect the enclosed absorber plate and create an insulating air space. This glazing material does not absorb the suns thermal energy to any significant extent and therefore most of the incoming radiation is received by the blackened absorber.

The air gap between the plate and glazing material traps this heat preventing it from escaping back into the atmosphere. As the absorber plate warms up, it transfers heat to the fluid within the collector but it also loses heat to its surroundings. To minimize this loss of heat, the bottom and sides of a flat plate collector are insulated with high temperature rigid foam or aluminium foil insulation.
