Background technology
Along with the enhancing gradually of growth in the living standard and environmental consciousness, the solar energy of cleanliness without any pollution has obtained application more and more widely.Solar water heater is ripe, the also very competitive green energy resource product economically of technical development in the present field of solar energy utilization, produce and life in obtained general promotion and application.
The solar water heater of selling in the market, what technical merit was the highest, sales volume is maximum is the all-glass vacuum thermal-collecting tube solar water heater.But full glass vacuum tube solar water heater is pressure-bearing not, can not shine by the lack of water sky during use, otherwise possibly cause the glass tube explosion; And glass tube communicates with water tank, as long as a pipe explosion is arranged, whole water heater just can not use, must be out of service, could change glass-vacuum tube after the sluicing.Therefore, all-glass vacuum thermal-collecting tube formula water heater is subject to many limitations in the application of severe cold area.
To the limitation of all-glass vacuum tube water heater, researchers have proposed the improvement measure, improve the performance that solar water heater uses at extremely frigid zones.

The flat plate heat tube solar thermal collector has the heat transfer efficiency height, and freezing tolerance is strong, can booster, and stable work in work, advantages such as long service life.But its heat loss is bigger, and per day efficient has only 50% or still less.
(5) heat pipe vacuum tube collector
Sunshine is passed to heat pipe evaporator section with heat after the glass tube with vacuum selectivity absorbs, give boiler through Working fluid phase changing with heat by heat pipe evaporator section.Compare with the flat plate heat tube solar thermal collector, heat pipe vacuum tube solar collector has the following advantages: heat loss is little, and average heat loss factor is less than about 1.0; The per day thermal efficiency is high; Bearing capacity is high, has solved duct ligation dirt and booster problem in the vacuum tube, and freezing tolerance is strong, can under-25 ℃ of conditions, use.But the sealing-in of metal and glass and sealing are main difficult problems, and a spot of leakage will cause solar collecting performance to descend rapidly, and collecting efficiency significantly reduces.
If the back at the heat pipe type vacuum tube adds concentrator, can increase the daylighting intensity of heat pipe type vacuum pipe, utilize the high characteristics of its solar collecting performance more fully.Small-sized concentrator coupling heat pipe vacuum tube collector can be improved collecting efficiency, and this type of heat collector is relatively simple for structure, not strict to caustic surface type requirement on machining accuracy, can make up with building roof, metope etc. easily.
