Abstract

The invention discloses a vacuum zamplate pipe type solar water heater. The design breaks through the following four technical problems which cannot be solved by a holohyaline solar water heater for a long time: 1, the planar lighting rate is low, which is caused by the clearance among the pipes; 2, heat energy waste is resulted from a large amount of inaccessible hot water in the pipes; 3, a hot water tank cannot be approximate to a right circular cylinder with high volume ratio due to the limitation of the pipe pitch and the capacity; 4, because of being not cleaned, the holohyaline solar water heater has low possibility to be mounted in a kitchen, so that the heat energy cannot be fully utilized. On the premise that all advantages of the holohyaline solar water heater are kept, the hot water yield is nearly doubled, and the cost is lower. In addition, as the vacuum zamplate pipe type solar water heater be is made of a new material capable of being recovered and degraded, the more environment-friendly and safer purposes are achieved. The vacuum zamplate pipe type solar water heater is an ideal product popularized comprehensively and upgraded.

Description

Vacuum zamplate pipe solar water heater

(1) technical field: renewable and clean energy resource.

(2) background technology: 1, flat-plate-type solar energy water heater is one of solar water heater who occurs the earliest, it is characterized in that the plane utilization rate is high, and security is good, because cost is too high, in China, seldom adopts.2, vacuum glass heat pipe formula solar water heater, hereinafter to be referred as full glass type or cylinder cast.Its characteristics are the vacuum layer high insulating effect 1.; 2. gross area heat exchange, heat transfer distances is short, obtains heating rate high; 3. tube pitch can be ventilative, and wind resistance power is strong; 4. material source is rich and easy to get, cheap.Economical and practical is its sharpest edges, accounts for 90% of China solar water heater market share.Shortcoming: plane efficiency and security are all not as plate.3, other: hat, Buddha's warrior attendant, without hindrance conduction in superconductive heat tube type, Zijin hat ... Deng the solar water heater, all only for reducing the water-holding quantity that can't take in glass-tube, design, gains and losses balance each other, even loses more than gain, though there is product to appear on the market, is difficult to also popularize in an all-round way application.

(3) summary of the invention: the design replaces cylindrical tube with the vacuum zamplate pipe and broken through insurmountable four large Pinch technology difficult problems since full glass type half a century: the multitube gap causes the plane utilization rate low; In pipe, a large amount of hot water of shop fixtures can't be taken and be caused energy waste; The restriction of acceptor center distance and production capacity, the right cylinder that heat storage water tank can't be high to volumetric ratio is drawn close; Can't clean also and advance the kitchen food and drink with regard to difficulty, heat energy purposes limitation.

Fusiformis pipe outside so-called zamplate pipe general reference cylindrical tube, oval pipe, flat tube etc.Because affected by optics, mechanics processing technology etc., it is combined mostly zamplate pipe is.

Though zamplate pipe is not so good as cylindrical tube on bearing capacity, but on unpressurized solar water heater, use, more than sufficient, another characteristics of zamplate pipe are that two shaft lengths need only reasonable in design in length and breadth, can make multiple choices, this break through just full glass type Pinch technology in the urgent need to geometric properties.Shorten vertically height, can limit the hot water amount of inadvisable use in interchanger, reduce thermal waste, and lengthen transverse width, reduced the number of pipe when increasing daylighting area, also reduced the gap number between two pipes, use and improve the plane lighting utilization rate.

According to GB: two tube center distancees 80, the vacuum diameter of inner pipe 47*1800 of full glass type, design standard hot water output 8L/ pipe, plane utilization rate 47/80=59%, shop fixtures water-holding quantity in pipe: diameter 47*1800=3.12 liter/pipe.

The design: two tube center distancees are 222, vacuum inner tube width 190, and its plane utilization rate is that 190/222=86% had both retained the strong characteristics of full glass type wind resistance power one by one, approaches again plate plane utilization rate.The design's vacuum inner tube width 190 is 4 times of glass-tube diameter 47, and design shop fixtures water-holding quantity is 3 liters/pipe, that is to say that the hot water that also has 9 liters can directly enter heat storage water tank standby.

The heat production water yield of every zamplate pipe=4*8+9=41L/ pipe.

Obviously, the hot water output that five zamplate pipes produce just reaches 200 liters, takes up an area widely by 1150, only has half of full glass type.Due to the restriction that is not affected or less affected by production capacity and centre-to-centre spacing, boiler can be as far as possible to volumetric efficiency high spherial body close.Be noted that right cylinder becomes its volumetric ratio of elongated cylinder and just equals 3.14.

3, outstanding characteristics and significant progressive being of the present invention:

1. realize all the time according to neutral gear and few sunshine neutral gear, daylighting area approach plate in, retained full glass type wind resistance power by force and other all advantages.

2. the shop fixtures hot water amount who reduces by 3/4 inadvisable use had not only increased hot water output but also had retained all physical characteristics of water.

3. the restriction of not managed centre-to-centre spacing and production capacity, heat storage water tank can directly be designed to right cylinder or to volumetric ratio high right cylinder draw close.

4. be convenient to clean, safe and sanitary can enter the kitchen food and drink.

5. adopt the new material of recyclable degraded to gradually reduce the permanent pollution that glass causes.

6. when hot water output is double, cost is lower than full glass type, and more non-plate institute is comparable, the development in economical and practical decision future of the present invention.
