Abstract
A microcirculation-type heat-collecting vacuum glass tube used for the water tank of solar water heater features that a heat exchanging tube is inserted in vacuum glass tube, the elastic filler is fixed in said two tubes, a permanent magnet is installed to the top of elastic filler, and a filter membrane is adhered to the top end of heat exchanging tube. Its advantages are high conductivity and utilization rate of heat, high antifreezing power, and no secondary pollution to water.
Description
Technical field:
The present invention relates to a kind of microcirculation glass heat-collecting vacuum tube, be used for and the supporting use of water tank above the solar water heater, belong to critical piece on the solar water heater.
Background technology:
Before the present invention makes, in the prior art, with the matching used glass-vacuum tube of water tank above the solar water heater be to the greatest extent the glass tube of a sky.The common glass-vacuum tube of this kind is mainly by following weak point: 1. glass tube uses easy scaling and the relatively poor area of settled sludge, especially water quality in the pipe of back through the long period, and incrustation scale makes the heat transfer efficiency of vacuum tube reduce fast very soon, even can't use; The sludgd deposition meeting causes the secondary pollution of water quality, and serious meeting causes the skin disease of human body; 2. not freeze proof, freeze in the pipe in the winter time and can rise brokenly by pipe; Therefore cold district need adopt electrical heating and be incubated in the winter time, the clear-cut emptying that has need not, make the effect of not bringing into play on the contrary the winter that needs most hot water; 3. self capacity is big, about the general every water of domestic demand by all means 1-2kg, 20 by all means Total Water can reach about 20-40kg, this self big capacity obviously influences the heat transfer efficiency of nature intensification thermal convection current in the winter time, having so simultaneously, a large amount of hot water can not use the same day, especially at the interrupted fine southern area of winter-spring season, thermal loss is huge.
Summary of the invention:
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of compact conformation, reasonable is provided; Be difficult for scaling and settled sludge in the pipe, can not produce secondary water and pollute; Self thermal capacity is low, and it is fast to conduct heat, the efficiency of utilization height; Frost resistance is good, still can operate as normal in-30 ℃ of temperature areas and microcirculation glass heat-collecting vacuum tube that can be not freezing.
Main solution of the present invention is achieved in that
The present invention adopts heat exchanger tube 3 skewers to go into glass-vacuum tube 1, and elasticity inserts 2 is contained in glass-vacuum tube 1 and heat exchanger tube 3 inside, and permanent magnet 7 is installed at elasticity inserts 2 tops, and filter membrane 6 is bonded at heat exchanger tube 3 tops.
Compared with the prior art the present invention has the following advantages:
Compact conformation of the present invention, rationally; Low cost of manufacture, use, installation, replacing are conveniently; Frost resistance is good, can be in-30 ℃ of temperature areas still can operate as normal and can be not freezing; Be difficult for scaling in the pipe, can keep high efficiency heat-transfer effect for a long time; Be difficult for settled sludge in the pipe, can not produce the water secondary pollution; Self thermal capacity is low, and it is fast to conduct heat, the efficiency of utilization height; Can directly replace and to use but ordinary vacuum tube that the thermal efficiency has reduced.
Description of drawings:
Fig. 1 is a structural front view of the present invention:
The specific embodiment:
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention mainly is made up of glass-vacuum tube 1, elasticity inserts 2, heat exchanger tube 3, macromolecular filtering film 6, rare-earth permanent magnet 7.Heat exchanger tube 3 skewers are gone in the glass-vacuum tube 1; adopt elasticity inserts (high temperature steeps last bar) 2 usefulness binding agents to be bonded in glass-vacuum tube 1 and heat exchanger tube 3 inside; top adhesive (installation) rare-earth permanent magnet 7 at elasticity inserts 2; macromolecular filtering film 6 bondings (installation) adopt protective cap 5 fastening on the top of heat exchanger tube 3 simultaneously.All adopt the sealing of sealing ring 4 adding additives at the mouth of pipe of glass-vacuum tube 1 and the joint portion of heat exchanger tube 3.
The operation principle of the present invention and the course of work:
1. after pipe inserted water tank, water entered in the pipe through macromolecular filtering film purified treatment, was magnetized at the same time, and to guarantee not having sludgd deposition in the long-term work pipe, scaling does not keep the high efficiency state always;
2. because high temperature steeps the filling effect of last bar, water content seldom in the pipe, and mainly distribute along tube wall, when being subjected to solar radiation, the inside pipe wall intensification can cause that water purification heats up rapidly in the pipe, and hot-water line rises to heat exchanger tube and water tank carries out heat exchange along tube wall, bottom cold water is back to along in the shade facial canal wall after the heat exchange, so repeatedly the heat of solar energy is constantly passed to water tank and whole process is all finished basically in pipe, form microcirculation in the pipe;
3. pipe is in the work of being heated with when cooling off night, and liquid in pipe and water tank have the trace exchange and replenish, with balance and the enough circulating fluids of keep-uping pressure;
4. because the elastic reaction of the last bar of bubble has solved freeze proof problem in severe winter, under-30 ℃ of environment, can not make pipe break, the expansion stresses of ice be steeped last bar absorption and protect pipe not to be subjected to stress rupture because of freezing yet.
Claims (2)
1. microcirculation glass heat-collecting vacuum tube, comprise glass-vacuum tube (1), it is characterized in that adopting heat exchanger tube (3) skewer to go into glass-vacuum tube (1), elasticity inserts (2) is contained in glass-vacuum tube (1) and heat exchanger tube (3) inside, at elasticity inserts (2) top permanent magnet (7) is installed, filter membrane (6) is bonded at heat exchanger tube (3) top.
