It collects the case and collects the case both sides, collects case antithetical couplet several glass evacuated collector tube entirely as an organic whole with the antithetical couplet at the antithetical couplet including the antithetical couplet, the portion is equipped with thermal -arrest water supply pipe and thermal -arrest return water pipe at antithetical couplet collection roof, be equipped with an axial guan zhongguan in the middle of antithetical couplet collection case, guanzhongguan bottom openings, it is unsettled above allying oneself with collection bottom of the case portion, be equipped with the baffle of an orifice plate formula between the thermal -arrest water supply pipe that allies oneself with the collection case and thermal -arrest return water pipe, the welding of guan zhongguan upper end on the drill way of baffle, the thermal -arrest water supply pipe UNICOM at guanzhongguan and top. The utility model discloses an ally oneself with collection incasement portion at traditional vacuum tube heat collector and manage in adding the tubulature, change heat collector business turn over water and water endless form, fried tub of phenomenon easily forming when the circulation is sail upstream once more after having eliminated thoroughly that the lack of water is empty in the heat collector vacuum tube and shining and winter the thermal -arrest circulating line freeze the danger of damage because of depositing the living quilt of aquatic products. This kind of solar collector manages in direct -current tube of vacuum can be applied to in the installation form of the multiunit of once establishing ties.
Description
Technical field
The utility model belongs to field of solar collectors, is specifically related to tube solar heat-collecting device in a kind of vacuum DC tube.
Background technology
Existing solar thermal collector thermal-arrest circulation time is intake from bottom, when thermal-arrest circulation stops, having heat collector water water-break phenomenon, causes lack of water air drying in heat collector vacuum tube, when again circulate upper water time easily form bombing, cause system to metal run out paralysis.
In the winter time, in thermal-arrest circulating line, water has again and is frozen the danger of damage, needs to take antifreezing measures.Generally take to install electric-heating belt additional or take thermal-arrest circulation anti-freezing mode.Electric-heating belt is antifreeze, and first this mode is increase investment cost, increases electric load simultaneously; And in use, also there are operation energy consumption and expense.And thermal-arrest circulation anti-freezing, this mode to utilize the hot water in heat storage water tank to carry out heating coil, can produce in order to the antifreeze heat loss brought.
Therefore, need improve the collecting system of existing solar thermal collector.
Summary of the invention
For the defect of existing solar thermal collector, the utility model provides a kind of new solar thermal collector---tube solar heat-collecting device in vacuum DC tube.
The technical solution of the utility model is:
Tube solar heat-collecting device in vacuum DC tube, the several all-glass vacuum thermal-collecting tubes comprising header and combine as a whole in header both sides, with header; Thermal-arrest water supply line and thermal-arrest water return pipeline is provided with at header top; Be provided with the tube-in-tube of an axis in the middle of the header, tube-in-tube bottom end opening, unsettled bottom header above; Between the thermal-arrest water supply line and thermal-arrest water return pipeline of header, be provided with the dividing plate of one piece of orifice-plate type, tube-in-tube upper end is welded on the aperture of dividing plate, the thermal-arrest water supply line UNICOM at tube-in-tube and top.
Thermal-arrest water supply line and thermal-arrest water return pipeline are located at the position higher than header; Thermal-arrest water return pipeline is positioned at below thermal-arrest water supply line.
Tube-in-tube adopts corrugated stainless steel tubing.
Plug is provided with bottom header.
The advantage that the utility model compares existing heat collector is:
The utility model installs tube-in-tube additional in traditional vacuum tube heat collector header inside, change heat collector Inlet and outlet water and water-cycling mode, the blasted pipe phenomenon easily formed when to completely eliminate in heat collector vacuum tube after lack of water air drying the upper water of circulation again and winter, thermal-arrest circulating line produced because of water is frozen the danger of damage, and decrease the consumption of electric energy.The utility model is welded as a whole by argon arc welding two pieces at tube-in-tube and header, firmly solid, durable in use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the A-A cross-sectional schematic in Fig. 1.
In figure: 1. header, 2. all-glass vacuum thermal-collecting tube, 3. tube-in-tube, 4. thermal-arrest water supply line, 5. thermal-arrest water return pipeline, 6. dividing plate, 7. plug.
Detailed description of the invention
The utility model is tube solar heat-collecting device in a kind of vacuum DC tube, and its structure is see shown in Fig. 1, Fig. 2:
Several all-glass vacuum thermal-collecting tubes 2 that in this vacuum DC tube, tube solar heat-collecting device comprises header 1 and combines as a whole in header 1 both sides, with header 1.In the position of header 1 top higher than header 1, be provided with thermal-arrest water supply line 4 and thermal-arrest water return pipeline 5, thermal-arrest water return pipeline 5 is positioned at below thermal-arrest water supply line 4.Be provided with the tube-in-tube 3 of an axis in the middle of the header 1, tube-in-tube 3 bottom end opening, unsettled bottom header 1 above.Tube-in-tube 3 adopts corrugated stainless steel tubing.Between the thermal-arrest water supply line 4 and thermal-arrest water return pipeline 5 of header 1, be provided with the dividing plate 6 of one piece of orifice-plate type, tube-in-tube 3 upper end is welded on the aperture of dividing plate 6, thermal-arrest water supply line 4 UNICOM at tube-in-tube 3 and top.Bottom header 1, be provided with plug 7, the water of header 1 inside be isolated from the outside, and water can be released when opening.
Water-cycling mode of the present utility model is: enter in tube-in-tube when cold water enters middle core pipe from the thermal-arrest water supply line 4 at header 1 top, flow out to header 1 from tube-in-tube 3 bottom, current enter the all-glass vacuum thermal-collecting tube 2 of both sides, get back to after all-glass vacuum thermal-collecting tube 2 Inner eycle in header 1, because intake pressure does not stop upwards to flow, finally flow out from thermal-arrest water return pipeline 5, form the circulation of whole system in outside.
Because water inlet realizes double back journey in heat collector, first preheating heats up again, fully improves collecting efficiency, and avoids the direct impact of cold water line up, stops blasted pipe phenomenon.
Thermal-arrest water supply line 4 and thermal-arrest water return pipeline 5 are higher than the position of header 1, and possess tube emptying condition, the idle that can realize winter is antifreeze, reduce heat loss, improve thermal-arrest usefulness.
Depict water (flow) direction in header 1 in accompanying drawing, because the current in all-glass vacuum thermal-collecting tube 2 are same as the prior art, do not draw in figure.
In this vacuum DC tube, tube solar heat-collecting device can be applicable to connect in the installation form of many groups.
