Description

The two circulating solar energy water heaters of overall plastic direct-insert pressure-bearing
Affiliated technical field
The present invention relates in the solar thermal utilization to use a kind of whole year solar water heater, the two circulating solar energy water heaters of especially a kind of overall plastic direct-insert pressure-bearing.
Background technology
At present, domestic commercially available solar water heater, the overwhelming majority is the non-pressure-bearing single cycle of a straight cutting solar water heater, it is low that this product has price, the new high advantage of machine water temperature, owing to be single cycle, when the water in the water tank directly enters the solar energy vacuum tube heating, cause a large amount of foulings in the vacuum tube, according to surveying and determination, solar vacuum-tube water heater heat, can descend in 3 years more than 50%, for addressing this problem, common way is that the magnesium rod is installed in water tank, do the scale velocity that only can make in the vacuum tube like this and slow down to some extent, can not fundamentally stop the generation of fouling; Because they can not pressure-bearing, to use and once will go up water once, operation is trouble very, if increase water level auto control system, has both increased the cost of product, has reduced the reliability of system again.Though heat pipe type vacuum pipe belongs to two periodic duty forms, its condensation end need be manufactured in addition, consume a large amount of precious metals.Because the condensation end area is very little and operating temperature is very high, thus condensation end fouling and its heat transfer efficiency is descended greatly especially easily, furthermore its price also is difficult to be accepted by domestic consumer.
Summary of the invention
For addressing the above problem, the invention provides the two circulating solar energy water heaters of a kind of overall plastic direct-insert pressure-bearing.
The technical solution adopted for the present invention to solve the technical problems is: cannelure 18, arc 19, arc 9, part water tank wall, cannelure 28, arc 27 surround collector 16, a plurality of vacuum tube patchholes are arranged on the water tank wall, be with cushion rubber in the vacuum tube patchhole, the upper end of full glass three chamber vacuum solar heat-collecting pipes 3 is inserted collector 16 and is with in the hole of cushion rubber, and insert in the hole of tail box 1 lower end; In end cap, the water tank wall enhancement layer is arranged; Form looping pit after cannelure on the end cap and water tank combine, a plurality of holes 14 in looping pit and the water tank wall are interconnected, and looping pit and inflation fluid hole are interconnected, and looping pit and collector are interconnected; Blast pipe 31 is connected with looping pit 24.
Enhancement layer in end cap, the water tank wall is tubulose or netted or helical form, or fiber dispersion shape structure, what enhancement layer was used is metal material or glass or carbon fibre or chemical fibre or steel fibre or ceramic fibre or natural fiber or string or fibrous composite; Hole 14 in the water tank wall is circular or oval or triangle, or polygon, and a plurality of holes are arranged in the water tank wall; End cap, water tank macromolecular material, modified polymer material, composite high-molecular material manufacturing; Enhancement layer in water tank, the water tank wall, hole, the vacuum tube patchhole on the water tank wall, inflation fluid hole, the arc 9 injection machine integrated injection molding in the water tank wall; Enhancement layer in the water tank, water tank wall, hole, inflation fluid hole, the integrated extrusion molding of arc 9 usefulness extruders in the water tank wall, or with two kinds or the two or more integrated coextrusion molds of macromolecular material, reinforcing material; Effective injection machine integrated injection molding on arc on end cap, the end cap, the plate on the end cap, the pipe on the end cap, the cannelure on the end cap, the cannelure.
In the fixing card 2 of pipe, the fixing card 8 of interior pipe interior pipe 7 biasings are fixed on the lower wall of heating chamber 6.
Electric heater 20 is installed on the end cap 21.
The invention has the beneficial effects as follows that the part of water tank wall is again the part of collector pipe, a plurality of apertures in the water tank wall provide circulation canal for heat cycles, and water tank wall itself is exactly a heat exchanger, has so both saved raw material, has improved heat transfer efficiency again.
The present invention is the two periodic duty standards of pressure-bearing, and heat cycles liquid is antifreeze, can use and can freezing heat collector at extremely frigid zones.
The present invention is the two periodic duty standards of pressure-bearing, never fouling in the heat collector.
Of the present inventionly advance/water system is in the pressure-bearing duty, not only can save water level auto control system, and simple to operate in addition, the high advantage of spray pressure.
There is not empty shortcoming of shining bombing in circulation fluid abrim forever in the heating circulation system of the present invention.
The present invention has enough big heat exchange area, thereby thermal resistance is little and heat exchange temperature is low, and is less scaling on the heat-exchange surface, can keep higher heat exchanger effectiveness forever.
A plurality of inflation fluids hole is arranged in the water tank wall of the present invention, can save the inflation fluid case.
Heating circulation system of the present invention is in non-pressure-bearing duty, can adopt the regular solar vacuum heat collection pipe, this both can keep the high advantage of regular solar vacuum heat-collecting tube efficiency, can save a large amount of non-ferrous raw materials again, significantly reduce the manufacturing cost of system, make product that the stronger market competitiveness be arranged.
The present invention is efficient, pressure-bearing, low cost, two circulation, good heat insulating, and the family, factory, office, the school that are fit to temperate zone, frigid zone and extremely frigid zones use, and vast market prospect is arranged.
