Abstract
The utility model relates to a full-glass vacuum solar heat-collection tube for a portable boiling water heater, which belongs to the technical field of solar heat utilization. The utility model is suitable for a portable solar boiling water heater. The utility model has a technical key point that the seal end of an inner glass tube of the full-glass vacuum solar heat-collection tube is arranged outside a getter mirror face. Solar energy can also be absorbed. The utility model has the advantages that the temperature difference of the seal end and the open end of the inner glass tube is small. Boiling points can be rapidly achieved on both ends. The full-glass vacuum solar heat-collection tube for a portable boiling water heater can be used for the boiling water heater.
Description
The utility model relates to a kind of portable boiler complete glass vacuum sun thermal-collecting tube, belongs to the solar energy utilization technique field, is applicable to solar boiler.
Complete glass vacuum sun thermal-collecting tube, because its collecting efficiency height, heat waste is little, it is not affected by environment particularly to do the heat collector that heat collecting element constitutes by it, and is widely used in water heater, hot-water heating system, is well received environmental protection and energy saving product.This thermal-collecting tube is made up of inner glass tube 1-1, outer glass pipe 1-2, getter 1-3, metal clamps 1-4, metal clamps is the support of getter, support the blind end of inner glass tube simultaneously, deposit aluminium-nitrogen/aluminium solar selectively absorbing coating 1-5 on the outer surface of inner glass tube, be pumped into high vacuum 1-6 between the inside and outside glass tube, the inner surface of the outer glass pipe blind end getter minute surface 1-7 that evapotranspired, (the 1st page of 9-12 is capable for Chinese patent " a kind of novel all glass vacuum heat collection tube of solar energy " specification, ZL95215311.4) as shown in Figure 1.As seen from the figure, the getter minute surface overlaps with the blind end of inner glass tube, the blind end of inner glass tube is covered, make it can not absorb sunshine, therefore the temperature of the openend of inner glass tube is higher than the temperature of blind end, even making that the temperature difference of water reaches two, 30 degrees centigrade in the thermal-collecting tube, the water of inner glass tube blind end difficulty reaches boiling point, thereby can not be used for boiler.
The purpose of this utility model is the deficiency at prior art, proposes a kind of new technical scheme, makes the blind end of inner glass tube more consistent with the temperature of openend, can be used in boiler.
Technical essential of the present utility model is that the blind end of inner glass tube is exposed at outside the getter minute surface, makes the blind end of inner glass tube can absorb solar energy equally.
Below in conjunction with accompanying drawing the utility model is described in detail: structural representation of the present utility model as shown in Figure 2,2-1 is an inner glass tube, 2-2 is an outer glass pipe, 2-3 is that getter, 2-4 are metal clamps, deposit aluminium-nitrogen/aluminium solar selectively absorbing coating 2-5 on the outer surface of inner glass tube, be pumped into high vacuum 2-6 between the inside and outside glass tube, the inner surface of the outer glass pipe blind end getter minute surface 2-7 that evapotranspired.As seen from the figure, the blind end of inner glass tube is exposed at outside the getter minute surface, is not blocked, and can absorb solar energy equally, has reduced the temperature difference of inner glass tube blind end and openend, and the water of thermal-collecting tube openend and blind end can both reach boiling point very soon.
The temperature difference that the utility model has the advantages that the blind end of inner glass tube and openend is less, makes the water of thermal-collecting tube openend and blind end reach boiling point very soon, can be used for solar water heater.
In addition, also can make the inner glass tube blind end supported by metal clamps, and be free suspension status, can reduce heat waste, better effects if.The water of openend and blind end almost reaches boiling point simultaneously.
Portable boiler is 300mm-600mm with the length L of complete glass vacuum sun thermal-collecting tube, and the diameter D of inner glass tube is 30mm-60mm.
Description of drawings:
Fig. 1 is the complete glass vacuum sun thermal-collecting tube structural representation
Fig. 2 is the utility model structural representation
Fig. 3 is a boiler complete glass vacuum sun thermal-collecting tube structural representation
Embodiment:
Fig. 3 has provided an embodiment of the present utility model, and 3-1 is an inner glass tube, and 3-2 is an outer glass pipe, 3-3 is a getter, 3-4 is a metal clamps, and 3-5 is aluminium-nitrogen/aluminium solar selectively absorbing coating, and 3-6 is a vacuum, 3-7 is the getter minute surface, the blind end of inner glass tube is exposed at outside the getter minute surface, also can absorb solar energy, and the inner glass tube blind end is not supported by metal clamps, and be suspension status, reduced heat waste.The thermal-collecting tube length L is 300mm, and inner glass tube diameter D is 37mm.Water in this thermal-collecting tube, the two ends temperature difference is very little, almost reaches boiling point simultaneously.
