The utility model discloses a multifunctional solar collecting device, include the snakelike heat exchange line who is control by the stainless steel, water inlet and delivery port are drawn forth respectively to the heat exchange line both ends, and the cover is equipped with the glass pipe or runs through the glass board respectively at partial every straight section that is equipped with glass board and heat exchange line of heat exchange line's straight section respectively on every straight section of heat exchange line. The beneficial effects are that: because the heat exchange tube is the snakelike heat exchange line who is control by the stainless steel, therefore the pressure -bearing is effectual, can bear the pressure that is higher than tens times evacuated -tube solar water heaters, can store a large amount of water, can avoid taking place the booster phenomenon, because the cover is equipped with the glass pipe and perhaps is equipped with the glass board in heat exchange line's straight section part respectively on every straight section of heat exchange line, has improved the photic area greatly, collecting efficiency is high, and rate of heating is fast, energy -concerving and environment -protective, the usage is extensive, can be used to use as solar water heater heating device, big -arch shelter heating device and indoor heating heating device.
