Background technology
In the sun (energy) hot water engineering, there is the multiple sun (energy) heat collector, conventional: many all-glass vacuum thermal-collecting tubes (hereinafter referred to as " full glass-tube ") enter a solar heat collector forming to the mid-header of arranging by south and north by left and right opposed straight cutting, as shown in Figure 1; In figure, (1) is mid-header (0 °-15 °, inclination angle), notes, the inner chamber of existing mid-header (1) is cavity.(2) be full glass-tube.This heat collector materials are economized, cost is low, are the engineering solar heat collectors of domestic recoverable amount maximum, herein hereinafter referred to as " heat collector of the complete mid-header of the left and right straight cutting of glass-tube ".The bottom of this heat collector header has (cold) water inlet pipe, top to have (heat) water outlet pipe, each heat collector connects the collector system of the whole solar hot-water engineering of rear composition by series and parallel mode, then the composition such as configuration cycles water pump, heat storage water tank, robot control system(RCS) is adopted hot solar hot-water engineering by forced convertion; In addition, header inner core of solar water heater etc. all uses 0.3mm stainless sheet steel to make.These are all known technologies, lower summary.
Because mid-header (1) is cavity structure, when water circulating pump is inputted cold water, export from top hot water outlet pipe subsequently from mid-header (1) bottom cold water inlet tube, this forced convertion is adopted hot mode and can not all be taken out of gathering hot water in full glass-tube (2) tube chamber, be that its thermal efficiency does not reach maximum, be referred to as " thoroughly forced convertion mode is not adopted hot heat collector " herein; The present invention will overcome this class shortcoming.
Chinese patent ZL94200904.5 makes improvements above-mentioned " heat collector that mid-header forms ", sees Fig. 2.Along mid-header (1) lumen shaft to a longitudinal baffle with mozzle jack (4) being set, mid-header (1) inner chamber being divided into left and right two Room, some diaphragm plates of subsection setup (5) in left and right two Room in addition; One " being communicated with the mozzle (3) at two ends " is also set in addition, inserts the jack with the longitudinal baffle (4) of mozzle jack, two full glass-tubes (2) of arranged on left and right sides are communicated with.Like this, when water circulating pump is inputted cold water from mid-header bottom cold water inlet tube, the initial flow direction of current be from the 1st, the 2 full glass-tubes in left side (2) be communicated with the passageway of mozzle (3) at two ends enter full glass-tube (2) bottom, then along through the 1st, the 2 full glass-tubes in right side (2) of the mozzle (3) that is communicated with two ends bottom; Again along full glass-tube (2) and the 1st, the 2 full glass-tubes in outflow right side, passageway (2) inner chamber of mozzle (3) that is communicated with two ends, then go directly bottom golden glass-tube (2) in mozzle (3) passageway that enters the 3rd, the 4 full glass-tubes in right side (2) and be communicated with two ends; Enter the 3rd, the 4 full glass-tubes in left side (2) bottom from mozzle (3) again ... finally becoming hot water flows out from mid-header (1) top hot water outlet pipe ..., enter mid-header (1) bottom cold water inlet port series connection with it, that be positioned at another identical heat collector of top ... (being all known technology content-Lve subsequently).
Know from above, ZL94200904.5 provides a kind of hot mode of adopting of thorough forced convertion, and the thermal efficiency is naturally higher.But having half in the type of above-mentioned fluid flow path is not " counter force convection current " (containing meaning aftermentioned about " oppositely ").From lower surface analysis: in " heat collector that mid-header forms ", fluid flows while only having completely by counter force convection current, could ponding in heat collector be discharged completely by straightforward procedure.So-called " straightforward procedure " refers to: the water inlet pipe of mid-header (1) bottom is changed into drainpipe.Draining heat collector ponding is completely that extremely frigid zones prevents the conventional way of full glass-tube in bursting by freezing at night in winter.At night in extremely frigid zones winter, not exclusively the full glass-tube meeting bursting by freezing of heat is adopted in counter force convection current; Another shortcoming of ZL94200904.5 is that some tabulas of processing are pulled (5), will in utmost point narrow space, be carried out, and difficulty is large, be difficult to suitability for industrialized production.The present invention will overcome this class shortcoming.Fig. 2 is called the schematic diagram of " not exclusively oppositely thoroughly forced convertion mode is adopted hot heat collector ".
In a word, at " heat collector that the mid-header of the complete left and right straight cutting of glass-tube forms " category of solar hot-water engineering, most heat collectors are adopted heat by not thorough forced convertion mode, and the thermal efficiency is not high; Adopt hot technical improvements though propose thorough forced convertion, bring and make the defect of full glass-tube bursting by freezing night in severe cold winter.The present invention's " oppositely thoroughly forced convertion mode is adopted hot solar thermal collector completely " will overcome these existing technological deficiencies.
The content of invention
The present invention solves the problems of the technologies described above and adopts technical scheme main points to be: propose a kind of completely oppositely thorough forced convertion mode and adopt hot solar thermal collector, make in every full glass-tube tube chamber, all to go deep into a mozzle in heat collector, object is the technological deficiency that overcomes the low efficiency existing in " heat collector that the mid-header of the complete left and right straight cutting of glass-tube forms "; Due to " completely oppositely thoroughly forced convertion ", make it to drain easily ponding in heat collector, avoid the technological deficiency of bursting by freezing cold night in severe winter all-glass vacuum thermal-collecting tube.
Technical scheme of the present invention is that " heat collector that the mid-header of the complete left and right straight cutting of glass-tube forms " transformed, at mid-header inner chamber, one " U-shaped hydroecium " is set, every full glass-tube inner chamber arranges a mozzle, form " oppositely thoroughly forced convertion mode is adopted hot solar thermal collector completely ", thereby improve the thermal efficiency of heat collector, and can drain ponding by straightforward procedure, prevent the full glass-tube of bursting by freezing at night in severe winter.
Theing contents are as follows of transformation stated.Fig. 3 is the schematic diagram of " oppositely thoroughly forced convertion mode is adopted hot heat collector completely ".At mid-header (1) inner chamber, upper with mid-header (1) (or under) the parallel axial sectional plane of panel is set and is the hydroecium (being called for short U-shaped hydroecium herein) of U font, U-shaped hydroecium is by right side band mozzle flange jack dividing plate (7), base spacer (9), left side band mozzle flange jack dividing plate (8), the top of the dividing plate of totally three connections and mid-header (1) pull and on, lower two panels are welded (Fig. 5 shows thin portion), wherein base spacer (9) atresia, with mid-header (1) bottom about 20mm apart, after U-shaped hydroecium upper end is opened wide and is partly welded with mid-header (1) top board, (obviously above-mentioned " dividing plates of three connections " also can substitute with a sheet metal that is equivalent to " dividing plates of three connections ") just communicates with mid-header (1) top effluent pipe mouth, two left and right band mozzle flange jack is identical with the flange circular hole quantity that can insert full glass-tube (2) on mid-header (1) left and right side panel every the number of pulling the flange jack on (8), (7), also maintenance is concentric." flange circular hole " is industry idiom, and meaning is that it coordinates with silica gel ring for sealing, makes the pipeline inserting form sealed attachment.
The left or right side band mozzle jack dividing plate (8) of U-shaped hydroecium or each jack of (9) at mid-header (1) inner chamber first insert a mozzle (6), more full glass-tube (2) are inserted among each flanging bore of mid-header (1) arranged on left and right sides face [consequently: insert in each full glass-tube (2) tube chamber of header (1) and have a mozzle (6)]; Mozzle (6) is engineering plastics tubing, and diameter is 15mm to 30mm, and the full glass-tube of Length Ratio (2) is wanted short 100mm to 400mm, though each mozzle gos deep into full glass-tube (2) inner chamber not and the end.
Connect lower introduction: water circulating pump is the water inlet pipe input heat collector from mid-header (1) bottom water at low temperature, the culvert meaning of " counter force convection current " is described from the flow path of water.
By Fig. 3, stopped by the base spacer of U-shaped hydroecium (9) from the low temperature current of mid-header (1) bottom water inlet pipe input, just first in the passageway of the whole full glass-tube (2) from mid-header (1) and mozzle (6), arrive full glass-tube (2) bottom; Then enter U-shaped hydroecium from mozzle (6), after gathering, from the effluent pipe mouth output high-temperature water at mid-header (1) top, enter the water inlet pipe of " heat collector that the mid-header of the complete left and right straight cutting of glass-tube forms " bottom of another series connection.
So far know, because mozzle (6) gos deep into full glass-tube (2) tube chamber depths, adopt heat therefore can realize forced convertion thoroughly.In addition, the traditional approach of realizing forced convertion in the full glass-tube of inner chamber water-filling is: first water at low temperature enters mozzle through full glass-tube bottom and then flow out full glass-tube tube chamber from mozzle and the passageway of full glass-tube, and Chinese patent ZL93232591.2 is exactly an example; And current of the present invention just in contrast, therefore " counter force convection current " is named in this forced convertion thereby Fig. 3 is the schematic diagram that completely oppositely thorough forced convertion mode is adopted hot solar thermal collector.
The physical meaning of counter force convection current is: adopt the hot full glass-tube of inner chamber water-filling by counter force convection current, could all discharge wherein accumulating water by short-cut method.This is because the short-cut method of draining is that the water inlet pipe of mid-header (1) bottom is changed into drainpipe, so current approach is just contrary when intaking when draining.When counter force convection current, first water arrive full glass-tube (2) bottom from " passageway of full glass-tube (2) and mozzle (6) ", when draining, also flows out from this " passageway ", and this just can drain ponding.Might as well analyze the ZL94200904.5 of " not exclusively counter force convection current ", taking the left and right two full glass-tubes of row (2) minimum in Fig. 2 as example, wherein the two full glass-tubes in right side (2) are by " forward forced convertion ", when draining, current must be discharged from the mozzle in middle position (6), can only discharge 50% ponding.The present invention is that " counter force convection current completely " can 100% drain ponding in heat collector easily, prevents at the full glass-tube of extremely frigid zones winter bursting by freezing at night (2).
In sum, main points of the present invention have three:
One, mid-header (1) inner chamber of the heat collector forming at the mid-header of the left and right straight cutting of all-glass vacuum thermal-collecting tube arranges a hydroecium parallel with mid-header (1) top panel, axial sectional plane is U font, i.e. U-shaped hydroecium; U-shaped hydroecium is by right side band mozzle flange jack dividing plate (7), base spacer (9), left side band mozzle flange jack dividing plate (8), and the top board of the dividing plate of totally three connections and mid-header (1) and upper and lower two panels are welded; Base spacer (9) atresia, with mid-header (1) bottom at a distance of about 20mm; U-shaped hydroecium upper end just communicates with mid-header (1) top effluent pipe mouth after opening wide and partly welding with mid-header (1) top board; The number of left side band mozzle flange jack dividing plate (8) or right side band mozzle flange jack dividing plate (7) flange jack is above identical with the flange circular hole quantity that can insert full glass-tube (2) on mid-header (1) left and right side panel, and maintenance concentric.
They are two years old, the assembling that completely oppositely thorough forced convertion mode is adopted hot solar thermal collector is all first to insert a mozzle (6) at the left side band mozzle jack dividing plate (8) of U-shaped hydroecium and each jack of right side band mozzle jack dividing plate (9) of mid-header (1) inner chamber, more full glass-tube (2) is inserted among the flanging bore of mid-header (1) arranged on left and right sides face; Mozzle (6) is engineering plastics tubing, and diameter is Φ 15mm to Φ 30mm, and the full glass-tube of Length Ratio (2) is wanted short 100mm to 400mm.
They are three years old, the current approach of completely oppositely thoroughly forced convertion of the present invention be water circulating pump water at low temperature from the water inlet pipe input of mid-header (1) bottom, low temperature current are stopped by the base spacer of U-shaped hydroecium (9), just first in the passageway of the whole full glass-tube (2) from mid-header (1) and mozzle (6), arrive each full glass-tube (2) bottom; Then enter U-shaped hydroecium from each mozzle (6), the effluent pipe mouth from mid-header (1) top after gathering is exported high-temperature water; Then enter that another is identical, the water inlet pipe of " oppositely thoroughly forced convertion mode is adopted hot solar thermal collector completely " bottom of series connection.
