Abstract: Several pieces of rectangular honeycomb structures of different cell dimensions or cell wall thicknesses are manufactured with transparent insulation material film, and the contrast sunning tests on the honeycombed plate solar collector and the common plate collector are made. The tests shows that the absorber of the honeycombed plate collector keeps an obviously higher balance temperature than the ordinary collector does and the effect is better when the dimension of honeycomb cell is smaller or the wall of honeycomb cell is thinner. The analysis of the efficiency of the collector also shows that the efficiency of the collector with honeycomb panel is much higher than that of the ordinary plate collector.

Key words: honeycomb structures, balance temperature, efficiency
