Abstract
A heat driven liquid close-loop automatic circulating system is provided. This system circulates the liquid in a close-loop by the collected heat in the loop. The system may operate without external power for the pump. The heat driven liquid close-loop automatic circulating system may employ a modified self-powered pump for heated liquid. The pump includes an airtight container for containing the heated liquid, a inlet and a outlet of the heated liquid, further more the modified self-powered pump has a breathing channel with a liquid vapor condensing and reflux structure. The heat driven liquid close-loop automatic circulating system may be a solar heated liquid close-loop automatic circulating system with a solar heat collector.
Claims12
A heat driven liquid self-circulating system, comprises:
- a heat collector having a heat collector inlet and a heat collector outlet;
- said heat collector outlet is not lower than said heat collector inlet;
- a heat driven self-circulating device for heated liquid, used with said liquid heat collector, comprising:
- an container/liquid tank for containing heated liquid, having a upper space above said heated liquid's level surface;
- an heated liquid inlet and a heated liquid outlet arranged on said airtight container/liquid tank, wherein said heated liquid outlet is under the liquid level surface, and said heated liquid inlet is not lower than said heated liquid outlet;
- and
- a breathing channel always connecting atmosphere with said upper air/vapor space, wherein said breathing channel has a liquid vapor condensing and refluxing structure;
- and
- a first connecting conduit connecting to said heat collector outlet and said heated liquid inlet, wherein said heated liquid inlet is not lower than the heat collector outlet;
- wherein said heat collector is a solar heat collector.
