Description
Technical field
The utility model relates to a class to be made wherein fluid form in order by the structure that changes the solar energy heating guard system to flow, cause the thermal efficiency of thermal-collecting tube system to be improved; Be particularly useful for adopting the thermal-collecting tube system of the detachable solar hot-water heating system of all-glass vacuum thermal-collecting tube.
Background technology
Split (from) characteristics of formula solar water heater/system are that heat storage water tank is separated from each other, has pipeline to be communicated with therebetween with thermal-collecting tube system (claiming " heat collector " again); The thermal-collecting tube system inserts a union pipe (" header ") by many thermal-collecting tubes (this paper only relates to all-glass vacuum thermal-collecting tube, abbreviation " full glass-tube ") and forms.
For saving cost, the structure (internal placement mode) of existing large-scale thermal-collecting tube system is: a foundation this by union pipe of " south-north " orientation in central authorities, many " full glass-tube " basic by " Dong-Xi " orientation, substantially by horizontal direction from a left side/right bilateral symmetry ground inserts union pipe; Union pipe (pipe) chamber is " cavity ", and its underpart has cold water to enter the mouth of pipe, hot water delivery pipe's mouth is arranged at top; Adopting hot mode is generally undertaken by the forced convertion mode with circulating pump.This paper is called for short " central opposed type union pipe " to this union pipe in the thermal-collecting tube system; If " central opposed type union pipe " left side/right both sides respectively have 20 circular holes to insert adaptive " full glass-tube ", then be called for short " 40 holes central authorities opposed type union pipe ".
The shortcoming that hot mode is adopted by this thermal-collecting tube system is: circulating pump order about cold water from the union pipe bottom with bigger flow velocity, flow out from union pipe top via the cavity of union pipe, this " simple procedure " can not illustrate, actual also can not be the hot water that accumulates in " full glass-tube " chamber of both sides, union pipe chamber all in company with taking away.Practice finds, when full glass-tube length exceeds 1.5m then " effect is bad ", and Here it is clear proof.That is existing split type solar hot water system's thermal-collecting tube system, its thermal efficiency reaches it far away should value; Or split type solar hot water system's the thermal efficiency (heating rate) does not reach it value should be arranged.
Must abandon the union pipe of this " cavity " formula structure for improving the thermal efficiency.The purpose of this utility model is to propose a kind of " the union pipe chamber is provided with has the thermal-collecting tube system of cold water pore dividing plate ", makes the fluid in the thermal-collecting tube system form orderly flowing, and split type solar hot water system's the thermal efficiency (getting heating rate) is significantly improved.
The utility model content
The utility model intension is at the tube chamber of above-mentioned existing " cavity type " central opposed type union pipe two dividing plates (being called for short dividing plate with holes) with row's circular hole to be installed vertically, makes the thermal-collecting tube system that has split type solar hot water system now become " the union pipe chamber is provided with has the thermal-collecting tube system of cold water pore dividing plate " of this case.
Fig. 1 is " the union pipe chamber is provided with has the thermal-collecting tube system of cold water pore dividing plate " generalized section along its principal plane, (4) are that dividing plate with holes, (1) are union pipe (shell) among the figure, each Circularhole diameter and structure straight tube (with O-ring seal) degree of being in the dividing plate with holes (4) be able to hold an about 20mm of diameter, and pitch of holes just equals the pitch-row of union pipe (1) both sides straight cutting " full glass-tube " (3) each circular hole, and two row's circular holes are " with one heart " in projection.With union pipe (1) inwall driving fit, this just is separated into " three spaces (chamber) " to union pipe (1) tube chamber around two dividing plates with holes (4).Because there is the hot water input in " left side/right two Room " original just space of inserting many " full glass-tube " (3) in " three Room ", becomes " hot hydroecium ", its duct, top becomes hot water outlet (Y); " round " of " medial compartment " both sides inserts cold water inlet pipe (2), go deep into " full glass-tube " (3) tube chamber (apart from bottom 100-500mm), " medial compartment " below pipe hole (X) will link to each other with the cold water inlet pipe road, by making water at low temperature enter " medial compartment " via cold water inlet (X), go deep into each " full glass-tube " (3) through each cold water inlet pipe (2) again, the hot water that displacement is accumulated, export from hot water outlet (Y), so " medial compartment " is called " cold water chamber " naturally, so this case disclosed " union pipe " belongs to " separated chamber style union pipe ", this structure guarantees heat-transfer fluid energy " mobile in order " (seeing embodiment) in the thermal-collecting tube system, effectively each " full glass-tube " (3) intraluminal hot water is all drawn, the thermal efficiency is heightened.
In brief, the characteristics of thermal-collecting tube of the present utility model system are: at union pipe (1) lumen shaft of existing " central opposed type union pipe " to settling two dividing plates with holes (4), union pipe (1) tube chamber is separated into three Room, the side of two Room respectively has row's circular hole and can insert all-glass vacuum thermal-collecting tube (3) in the usual way wherein, about two Room upper ends hot water outlet (Y) is arranged; The two sides of medial compartment are dividing plate with holes (4), and there is cooling water inlet (X) lower end of medial compartment.Dividing plate with holes (4) offer vertically row's circular hole with about row's circular hole maintenance of side of two Room concentric, its aperture allows to insert a cold water inlet pipe (2) of being with the diameter 10mm-25mm (best 15mm) of O-ring seal, and the length of cold water inlet pipe (2) will be lacked 200mm-600mm (best 350mm) than the length of all-glass vacuum thermal-collecting tube (3).Among the figure, (a-a) being " full glass-tube " axis of (3), union pipe (1) axis that (p-p) is, is (α) with (p-p) angle (a-a), and α shown in Figure 1=90 ° are traditional inserted modes, i.e. " direct insertion "; When α then becomes " angle-inserting type " between 90 °-82 °.This case is applicable to " straight/angle-inserting type " thermal-collecting tube system simultaneously.
When (X) links to each other with solar hot water system's circulating pump delivery outlet end, (Y) links to each other with circulating pump input port end, heat is adopted by " forced convertion circulation " mode by the hot water system.When (X) and (Y) respectively with pipeline directly with lay pinnacled heat storage water tank bottom and be connected, then hot-water heating system " free convection circulation " mode of pressing is adopted heat.This case all is suitable for these the two kinds solar hot water systems that adopt hot mode.
The utility model has the advantages that structure letter, the hot water of economizing, can thoroughly replace each " full glass-tube " (3) with material heighten the thermal efficiency, promptly " cost performance " height is its outstanding advantage.
