Abstract
The utility model discloses a vacuum tube solar water heater which comprises a water tank and a heat collector tube. The heat collector tube comprises a metal heat conducting tube, a fin and a glass vacuum heat collector tube, as well as a collecting header; the water tank, the collecting header and the heat collector tube are connected in sequence from top to bottom; the collecting header is connected with the metal heat conducting tube in the heat collector tube; and the collecting header is connected with the water tank through a hot water tube and a cold water tube. The vacuum tube solar water heater has high thermal insulation property, and is convenient to manufacture, install and maintain.
Description
Technical field
The utility model relates to a kind of solar energy equipment, relates in particular to a kind of solar vacuum-tube water heater.
Background technology
Existing solar vacuum-tube water heater adopts vacuum tube and the direct-connected structure of water tank, vacuum tube comprises metal heat-conducting pipe, fin and glass heat-collecting vacuum tube, it is by the heat energy of fin with the conversion of the solar energy that absorbs in the vacuum heat collection pipe, then by the metal heat-conducting pipe with in the thermal energy conduction entry.This design generally needs 15-30 root metal heat-conducting pipe to link to each other with water tank, and its manufacturing, installation and maintenance are comparatively complicated.
Summary of the invention
Technical problem to be solved in the utility model is existing solar vacuum-tube water heater complex structure, manufacturing expense height, be unfavorable for the shortcoming of installing and keeping in repair.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of solar vacuum-tube water heater, comprise water tank and thermal-collecting tube, described thermal-collecting tube comprises metal heat-conducting pipe, fin and glass heat-collecting vacuum tube, also comprise a header, water tank, header and thermal-collecting tube are connected from top to bottom in turn, and header is connected with metal heat-conducting pipe in the thermal-collecting tube, and header is connected with water tank with cold water pipe by hot-water line.
In the utility model, water tank and header are positioned on the same support, and adopt header to connect water tank and thermal-collecting tube indirectly, compare by the structure that 15-30 root metal tube is connected with water tank with thermal-collecting tube in the prior art, water tank and the extraneous heat dissipation channel that communicates have been reduced, help improving the heat-insulating property of water tank, be convenient to make, install and maintenance.
For further improving the heat-insulating property of water tank, described hot-water line and cold water pipe are provided with attemperator outward.Described attemperator can adopt the muff of existing insulation material making, is enclosed within the outside of water pipe.
As a kind of improvement project of the present utility model, described hot-water line connects the top of water tank and the top of header, and described cold water pipe connects the bottom of water tank and the bottom of header.The Natural Circulation of the water in water tank and the header is convenient in this design.
For improving the flexibility of making, to be convenient to manufacture, described hot-water line all is connected with header from the bottom of water tank with cold water pipe.
For further improving the flexibility of making, to be convenient to manufacture, described hot-water line is connected with header from two of water tank relative sides or same side with cold water pipe.
Advantage of the present utility model is: the heat-insulating property height, and be convenient to make, install and maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model (hot-water line is connected with header with two sides of cold water pipe from water tank);
Fig. 2 is structural representation of the present utility model (hot-water line is connected with header with the side of cold water pipe from water tank);
Fig. 3 is structural representation of the present utility model (hot-water line is connected with header with the bottom of cold water pipe from water tank).
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, solar vacuum-tube water heater comprises water tank 1, header 2 and thermal-collecting tube 3, described thermal-collecting tube 3 comprises metal heat-conducting pipe, fin and glass heat-collecting vacuum tube, described header 2 is between water tank 1 and thermal-collecting tube 3, its upper end is connected with water tank 1 with cold water pipe 5 by hot-water line 4, and the lower end is connected with metal heat-conducting pipe in the thermal-collecting tube 3.
As shown in Figure 2, hot-water line 4 all is connected with header 2 from a side of water tank 1 with cold water pipe 5.
As shown in Figure 3, hot-water line 4 is connected with header 2 with the bottom of cold water pipe 5 from water tank 1.
Water in the thermal-collecting tube 3 in the metal heat-conducting pipe imports the header that is connected by free convection with the heat of conversion of solar energy, because hot-water line is connected the bottom that top, the cold water pipe of water tank, header are connected water tank, header, therefore, the hot water that heats on header top can flow into the water tank upper strata by hot-water line, and the cold water of water tank lower floor flows into the header bottom by cold water pipe, thereby the mode of the heat in the header by free convection imported water tank.
