The utility model discloses a plate-type air-water dual-purpose solar thermal collector and belongs to the technical fields of solar energy utilization and building energy conservation. The plate-type air-water dual-purpose solar thermal collector comprises a frame, a light-transmitting cover plate, a thermal collecting plate, a plurality of branch water pipes, fins, a back plate, a water incoming header and a water outgoing header. The light-transmitting cover plate and the thermal collecting plate are sequentially fixed to the frame; the branch water pipes are arranged on the lower portion of the thermal collecting plate and form streaming channels with the water incoming header as well as the water outgoing header; an air duct is formed between the back plate and the thermal collecting plate. Fittingly used with a traditional solar air thermal collector, the plate-type air-water dual-purpose solar thermal collector heats air for heating in winter and heats domestic hot water in spring, summer and autumn seasons, situations that the air thermal collector is stuffily dried in summer and a hot water thermal collector is frozen in winter are avoided, annual utilization of the collector is improved, and economical efficiency of the collector is enhanced.
