摘要：

An analysis is presented for the performance of an inexpensive sand collector for solar energy which has been validated experimentally. The collector consists of a plane network of polyethylene pipes buried in a sand mass which is kept in a wooden case, the top surface of the sand being fixed by mixing with sodium silicate, blackened with blackboard paint spray and suitably glazed. The heat can be extracted by fluids passing through the pipes. The efficiency increases with the flow rate and decreases with the depth of the plane of heat retrieval.
