Description
Technical field
The present invention relates to a kind of thermal-collecting tube, comprise the solar thermal collector of thermal-collecting tube and the solar water heater that uses solar thermal collector.
Background technology
Existing vacuum heat collection pipe mainly contains all-glass vacuum thermal-collecting tube, mainly adopts direct insertion installation, and advantage is that cost is low, and shortcoming is: pressure-bearing not; Communicate with water tank in the pipe in it, interior pipe is leaked water, easily fouling; The easy bombing of water on when high temperature; Leak after the breakage.And the thermal-collecting tube of energy pressure-bearing mainly contains heat collector tube pipe and U type pipe thermal-collecting tube, and advantage is a pressure-bearing, and shortcoming is the cost height.
Summary of the invention
The purpose of this invention is to provide a kind of energy pressure-bearing, price again than heat pipe thermal-collecting tube and the low thermal-collecting tube of U type pipe thermal-collecting tube.
This thermal-collecting tube comprises glass-vacuum tube, and the metal tube that an end seals an end opening extend in the interior pipe of glass-vacuum tube, is provided with heat-conducting medium between the outer wall of the inwall of pipe and metal tube in glass-vacuum tube.
Its operation principle is: glass-vacuum tube changes heat energy into after absorbing solar energy, passes to metal tube (as copper pipe, stainless steel tube, aluminum pipe or other metal tubes) by the inwall of interior pipe through heat-conducting medium, and then the water in the heating metal pipe.
The beneficial effect of this thermal-collecting tube: 1, leak water the energy pressure-bearing in the metal tube; 2, do not leak water non-scaling in the glass-vacuum tube; 3, long service life; 4, water on when glass-vacuum tube high temperature, glass-vacuum tube can bombings yet; 5, do not leak water in the glass-vacuum tube, water-tight after the glass-vacuum tube breakage.
As the further improvement to above-mentioned thermal-collecting tube, heat-conducting medium is the heat transmission fin that contacts with the inwall of pipe in the glass-vacuum tube with the outer wall of metal tube respectively.
As the further improvement to above-mentioned thermal-collecting tube, heat-conducting medium is a conduction oil.
The present invention provides a kind of solar thermal collector that adopts above-mentioned thermal-collecting tube simultaneously, and it comprises a plurality of above-mentioned thermal-collecting tubes, and the metal tube openend in each thermal-collecting tube also is connected on the collector.When this solar thermal collector used on solar water heater, the two ends of collector communicated with the water tank of solar water heater respectively.Water in the metal tube through collector again with solar water heater water tank in the water circulation, thereby the water in the heating water tank.
As the further improvement to above-mentioned solar thermal collector, the metal tube openend in each thermal-collecting tube becomes removable seal to be connected (as being threaded) with collector.Metal tube can be disassembled from collector like this, be convenient to the clean metal pipe.
As the further improvement to above-mentioned solar thermal collector, it comprises that also inside is provided with the header of heat-insulation layer, and collector passes the heat-insulation layer in the header.
The present invention provides a kind of a kind of solar water heater that adopts above-mentioned solar thermal collector simultaneously, and it comprises water tank and above-mentioned solar thermal collector, and the collector two ends communicate with water tank respectively.Water in the collector of solar thermal collector by forced circulation or Natural Circulation, imports heat into water tank again.Preferably the collector two ends communicate with water tank by heat collector water inlet pipe and heat collector outlet pipe respectively; Heat collector water inlet pipe or heat collector outlet pipe are provided with circulating pump.Make water forced circulation in collector and the water tank by circulating pump, the hot water water tank inlet in the collector, cold water flows into collector by water tank, thus the water in the heating water tank.
Description of drawings
Fig. 1 is the schematic diagram of solar water heater.
Fig. 2 is the cross section enlarged drawing of the thermal-collecting tube among Fig. 1.
The specific embodiment
Referring to the thermal-collecting tube 5 of Fig. 2, copper pipe 1 lower end closed, upper end open, the copper pipe upper end is provided with external screw thread.Copper pipe 1 extend in the interior pipe 21 of glass-vacuum tube 2.Become vacuum between the interior pipe 21 of glass-vacuum tube 2 and the outer tube 22.Heat transmission fin 3 is arranged between the outer wall of the inwall of pipe in the glass-vacuum tube and copper pipe, and contacts with them respectively.
Referring to the solar water heater of Fig. 1, it comprises solar thermal collector 8, water tank 9, circulating pump 10.Solar thermal collector 8 comprises a plurality of thermal-collecting tubes 5, collector 11, header 12.Metal tube openend in each thermal-collecting tube is connected on the collector 11 by thread seal.Header inside is provided with heat-insulation layer 13, and collector passes the heat-insulation layer in the header.
Collector 11 two ends communicate with water tank 9 by heat collector water inlet pipe 14 and heat collector outlet pipe 15 respectively; Heat collector water inlet pipe 14 is provided with circulating pump 10.
After absorbing solar energy, thermal-collecting tube 5 changes heat energy into, inwall by interior pipe is passed to heat transmission fin, pass to copper pipe 1 by heat transmission fin again, and the water in the heating copper tube, by free convection, hot water in the copper pipe 1 floats to the collector 11 of solar thermal collector, and cold water flows into copper pipe by the collector 11 of solar thermal collector, thus the water in the heating collector.Water in the collector of solar thermal collector by circulating pump 10 and the interior water forced circulation of water tank, imports heat into water tank again.
