Description
Technical field
The utility model relates to a kind of solar energy heat collection pipe, belongs to solar energy utilization technique.
Background technology
In the solar hot water system, the heat collector that the present heat collector of using mainly contains flat plate collector and constitutes with all-glass vacuum thermal-collecting tube and metal vacuum thermal-collecting tube.
Flat plate collector has simply, reliable, efficient, can pressure-bearing, be convenient to and advantages such as building combine, but can not be freeze proof, can not be directly used in icing regional.Can adopt the double loop freeze proof, but can make system complex, cost up, the also way of available evacuation and anti-freezing, but the emptying of its lower collector pipe is subjected to the restriction of its absolute altitude, is necessary for the emptying receptacles that it is provided with a low absolute altitude, also can make system's relative complex, the increase of controlling cost.
All-glass vacuum thermal-collecting tube low temperature good in thermal property, certain freezing tolerance is arranged, thereby can constitute the solar hot water system, flat solar hot water system, particularly the inoperable area of domestic solar water heater is substituted, and causes poor efficiency, deposition, fouling, bombing but its straight cutting mode in the solar hot water system uses makes water-filling in its glass tube and is difficult for a series of defectives such as combining with building.
For this reason, the all-glass vacuum thermal-collecting tube of various built-in metal runners occurs, can overcome the above-mentioned defective of direct insertion all-glass vacuum thermal-collecting tube, but still had some problems.Mainly be that U type pipe is easy to stop up in the elbow when single loop, and the double loop increases cost; The relative cost of concentric tubes is higher; The heat pipe mode promptly can not reduce thermal capacitance, have a heat exchange again, thereby efficient is lower; Use maximum all-glass heat pipe vacuum collector tubes, its thermal efficiency is still suitable with direct insertion all-glass vacuum thermal-collecting tube, can not improve, also exist condensation end simultaneously and be easy to fouling, the cost height, performance degradation is very fast, life-span generally is no more than 10 years, even also has 3-5's.Gravity assisted heat pipe can not horizontal operation, when constituting balcony formula solar water heater, as vertical placement, uses radical to increase greatly, and this also can make cost improve, but and adopt the heat pipe of the built-in capillary of horizontal operation, equally also can make cost be difficult to reduce.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of efficient, reliable, can be freeze proof, do not produce bombing and longer solar energy heat collection pipe of life-span.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of solar energy heat collection pipe, it is a metal tube lower end closed and that be provided with thermofin, be characterized in, in metal tube, insert a partition bar it is divided into the back, two runners of sunny side, be provided with medium circulation passage between the lower end of partition bar and the blind end of metal tube, then be provided with or be connected to medium on the top of metal tube and import and export.
The utility model forms such closed circuit when work: cold medium enters back runner from the medium import, medium circulation passage through the metal tube bottom enters the sunny side runner then, thermal medium after heating flows out from media outlet, and medium is circulated therein in order.The utility model thermal-collecting tube can interiorly insert all-glass vacuum tube, or is encapsulated among the cavity of flat plate collector.When it is applied to the monoblock type full glass vacuum tube solar water heater, thermal-collecting tube is inserted the heat storage water tank inner bag with respect to the other end of blind end and is immersed in fully among the medium.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of solar energy heat collection pipe is characterized in that the medium import that is provided with is located on the metal tube that is positioned at back runner, and the upper end of partition bar then surpasses this medium import, and described media outlet is located at the top of metal tube.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of solar energy heat collection pipe is characterized in, the medium that is connected to is imported and exported to being connected on entrance branch and outlet stool metal tube top, that be communicated with back runner, sunny side runner respectively.
The utility model can constitute monoblock type and split type vacuum manifold, also can constitute flat-plate collector to be respectively applied for monoblock type vacuum tube solar water-heater and split type solar water heater who combines with positions such as the southern metope of building, balcony, oblique roofings and large-scale solar hot water system.
The utility model solar energy heat collection pipe can be obtained following good effect.
1) the utility model is compared with direct insertion vacuum heat collection pipe (hereinafter to be referred as direct insertion), owing to reduced thermal capacitance, can increase effective hot and the thermal efficiency is improved.
2) in the monoblock type water heater, to compare with direct insertion with heat pipe-type, the thermal medium after its heating directly enters water tank upper, thereby has strengthened water temperature delamination, and this also impels its thermal efficiency to be improved, and can use hot water as early as possible when top water is fetched water.
3) compare with direct insertion, do not have cold and hot quick-fried bombing problem.
4) compare with U type pipe, there is bigger space the corner of its media flow, thereby has reduced the possibility of stopping up.
5) compare with heat pipe, its structural manufacturing process is very simple, so cost reduces relatively, performance also not can as heat pipe decline, so its life-span is the life-span of material substantially since in water tank or collector not as the heat transfer process of heat pipe, so its efficient is height than heat pipe-type also.
6) the utility model is progressively advanced to the other end by blind end when icing, thereby has freezing tolerance.
