The utility model comprises a water pillow, a glass vacuum pipe, a valve set, a level meter, a temperature control device, a unit communicating pipe, a metal hot water extraction inner pipe, a hot water collection pipe, etc., wherein, the metal hot water extraction inner pipe penetrates through the water pillow and inserts into the bottom of the vacuum pipe, and the hot water collection pipe is buried in a heat-insulating layer of the water pillow. As the utility model uses the hot water extraction inner pipe, hot water of the vacuum pipe can carry out forced circulation heat exchange with cold water in the water pillow, heat efficiency is notably improved, and pollution in the vacuum pipe can be reduced; simultaneously, the utility model can be used by combining multiple units, which is convenient for a large-sized solar heating system in a building.
Description
The utility model belongs to solar energy heat collector, specifically a kind of solar vacuum-tube water heater.
When at present commercially available vacuum tubular glass solar collector was used for vertical and tilting installations of forward, the water that participates in flow circuit was the interior water of water tank, and the water in the vacuum tube is " stagnant water " that is difficult to flow.The water and the cold water heat exchange method in the water tank that are shone heat in the vacuum tube are based on the conduction of water body heat.The thermal convection theory that the hot water come-up cold water that is produced by the temperature difference descends often is subjected to the cold column blockings of formation such as hydraulic pressure effect in the practical application, make the heat in the vacuum tube be difficult to transmit out efficiently, and the thermal efficiency that finally shows as vacuum tube is significantly less than designing requirement.Simultaneously, the water that is stranded in for a long time in the vacuum tube makes the vacuum tube wall produce dirt and mixed and disorderly substances in pipe deposition, and the thermal efficiency of vacuum tube is descended gradually.The patent No. is that 93232591.2 and 95207259.9 Chinese patent has proposed the forced circulation of water filling tubular type and the vacuum tubular glass solar collector of guiding circulation respectively, its common trait is that cold water enters vacuum tube by water injection pipe, and hot water rises to water tank from the vacuum tube remaining space.The mode that water injection pipe has adopted metal and plastic material to weld in casing.The mode water outlet of this water injection pipe is still the water in the water tank, and water temperature is still on the low side, and also can incrustation in the vacuum tube; The solder joint easy-to-rust produces and stops up in the case; The plastics water injection pipe even is easy to temperature distortion or burns when lack of water in installation process.Simultaneously above-mentioned two patent working difficulty are very big, in especially difficult being applied to, large-scale central heating device.
It is main that the purpose of this utility model provides a kind of heat convection, the conduction heat exchange is the circulating solar vacuum-tube water heater of interior pipe that exceeds water temperature, high thermal efficiency of assisting, can family expenses, in more being applicable to, the large-scale centralized heating system, easily be automated control.
The purpose of this utility model is achieved in that it comprises water pillow (or claiming water tank), glass-vacuum tube, upper hose, downcomer and valve group, outside the water pillow heat-insulation layer is arranged, the water napex is equipped with vacuum tube, overflow pipe is arranged at water pillow top, it is characterized in that it comprises that also a hot water draws interior pipe, it passes water pillow straight cutting from water pillow top and goes into the vacuum tube bottom; Drew in heat-insulation layer pipe upper end in this hot water was drawn, and is connected with hot water collector in being embedded in heat-insulation layer; The hot water collector is communicated with downcomer; Be connected to water solenoid valve or water pump on the upper hose, be connected to down water solenoid valve on the downcomer, pass through water-circulating pipe and triple valve connection up and down between upper hose and the downcomer.The peak of water pillow is provided with liquid level gauge; Temperature sensor is housed in vacuum tube.In addition, the utility model is provided with water pillow communicating pipe, upper hose connected entrance, hot water collector connected entrance, to realize the tandem compound of a plurality of water heaters unit.
The utility model has the advantages that: in vacuum tube, be provided with hot water and draw interior pipe, can make the hot water in the vacuum tube directly get rid of also and can drain, improved leaving water temperature, reduced the incrustation of vacuum tube, prolonged the efficient phase of vacuum tube.In drawing by hot water pipe and valve arrangement can realize that water is rested the head on and vacuum tube in the water heat convection, improved the thermal efficiency; Liquid level gauge and the temperature sensor in the vacuum tube on the water pillow are controlled water solenoid valve and following water solenoid valve respectively, realize temperature control and liquid level control, have improved automatization level; Adopt the unit combination design be specially adapted in, the large-sized solar heat-collecting system.
Be described in detail the utility model below in conjunction with drawings and Examples.
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is hot water collector and the sewerage cross-sectional schematic among Fig. 1;
Fig. 3 is along the cross-sectional schematic of A-A line among Fig. 1.
As shown in the figure, water pillow 1, or claim water tank, and be the seal of a drum shape, the innermost layer is a water pillow inner bag 21, the outside is the heat-insulation layer 5 that is made of polystyrene foam plate and PU single-component polyurethane foamed material, is the shell made from reflectorized material 4 outside the heat-insulation layer 5.Water is rested the head on 1 bottom glass-vacuum tube 2 is housed, and the junction of the vacuum mouth of pipe and water pillow guarantees good seal by silica gel sealing ring 17, vacuum tube sheath 18, vacuum pore sealing ring 19.Pipe 3 was a metal thin tube in hot water was drawn, and passed water pillow straight cutting from water pillow top and went into vacuum tube 2 bottoms, passed water pillow place by silica gel sealing ring 22 sealings; Its upper end is crooked, and curved end 20 is inserted in the hot water collector 8.Hot water collector 8 is embedded in the cabinet insulation layer 5, and the one end leads to downcomer 33, and the other end is the hot water collector connected entrance 16 that is communicated with for a plurality of water heaters unit.Water is rested the head on the water of using when 1 top is provided with water inlet arm 7, overflow pipe 13, liquid level gauge 9, liquid level gauge lead-in wire 10 and supplies a plurality of unit to be communicated with and is rested the head on communicating pipe 14 etc.Water pillow bottom also is provided with blow-off pipe 29, blowdown on schedule.
