Abstract
The utility model discloses an automatic circulating water-passing heating system of solar water heater, which mainly comprises a heat insulation water tank (1), a vacuum heat collection tube (2), a cold pipe (3) and a water supplementing channel (4), wherein the upper end of the vacuum heat collection tube (2) is communicated with the heat insulation water tank (1), and the lower end of the vacuum heat collection tube (2) is communicated with the water supplementing channel (4); and the upper end of the cold pipe (3) is communicated with the heat insulation water tank (1), and the lower end of the cold pipe (3) is communicated with the water supplementing channel (4). After the system is adopted, the circulating way of cold water and hot water in the traditional heat collection tube is improved, the invalid accumulated water is fractionally existed in the heat collection tube, the circulation resistance is low, the circulating starting is rapid, the heating is rapid, and the exchange efficiency of the cold water and the hot water is improved, so that the heat energy generated by the heat collection tube can be fully utilized.
Description
Technical field
The utility model relates to a kind of solar water heater, and particularly a kind of solar water heater is circulated throughout water heating system automatically.
Background technology
Solar water heater can be converted into heat energy to solar energy, and water is heated to high-temperature from low temperature, uses to satisfy the hot water of people in life, production.
At present, family expenses thermal-collecting tube type solar water heater, natural circulation mode work is pressed in the circulation of its hot and cold water usually, does not have external power, the similar thermos bottle inner bag of the structure of its thermal-collecting tube, the afterbody of pipe seals.The circulation of hot and cold water is to carry out in thermal-collecting tube, and thermal-collecting tube is subjected to solar light irradiation surface temperature height, is the thermosphere face, and thermal-collecting tube back of the body sunshine surface temperature is low, is cold aspect, just produces the temperature difference like this in pipe.Because cold water is than great, hot water proportion is little, and the hot water on thermosphere face upper strata upwards floats, and enters in the attemperater; When hot water upwards floated, afterbody produced negative pressure in the pipe, and the cold water in the attemperater flows into to the cold layer of thermal-collecting tube (lower floor) and carries out moisturizing, thereby forms the Natural Circulation of hot and cold water, and fluidised form is a laminar flow.The endless form of this hot and cold water convection current belongs to microcirculation, and circulation resistance is bigger, and cycle performance is poor, add that invalid water (cold water) is too much in the thermal-collecting tube, the circulation start request temperature difference is big, and the hot and cold water exchange efficiency is low, and the heat energy that thermal-collecting tube is changed is not fully used.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of solar water heater to be circulated throughout water heating system automatically, thereby reduces the hot and cold water circulation resistance of solar water heater, improves the hot and cold water exchange efficiency, makes full use of the heat energy that thermal-collecting tube produces.
For solving the problems of the technologies described above the technical solution of the utility model: a kind of solar water heater is circulated throughout water heating system automatically.Mainly comprise attemperater, vacuum heat collection pipe, cold pipe and moisturizing passage, it is characterized in that: the upper end of described vacuum heat collection pipe is communicated with attemperater, the lower end of vacuum heat collection pipe and moisturizing channel connection; The upper end of cold pipe is communicated with attemperater, the lower end of cold pipe and moisturizing channel connection.
Said solar-energy water heater is circulated throughout water heating system automatically, and described vacuum heat collection pipe is oblate, the straight-through not back cover of pipe in it.
Aforesaid solar water heater is circulated throughout water heating system automatically, and described cold pipe is a round tube.
The beneficial effects of the utility model: compared with prior art, the utility model is a kind of novel solar water heater circulatory system, improved the endless form of hot and cold water in traditional thermal-collecting tube, its circulation resistance is very little, belong to strong circulation, this water mode of heating that is circulated throughout has improved the exchange efficiency of hot and cold water, and the heat energy that thermal-collecting tube is produced is fully utilized, thermal-collecting tube became the water heat tunnel, invalid water is few in the pipe, does not have the influence of invalid cold water, the having a narrow range of temperature of circulation start request, the circulation starting is fast, heating is fast, and the hot and cold water exchange efficiency is very high, and the efficiency of heating surface at the cloudy day is largely increased.
The utility model is designed to oblateness with thermal-collecting tube, compare with traditional circular thermal-collecting tube, not only can increase the light-receiving area of thermal-collecting tube, increase heating face, reduce invalid water in the pipe, improve the conversion ratio of solar energy, make intensification faster, and the sensitive surface of same area, can reduce the usage quantity of thermal-collecting tube, thereby reduce cost.Cold pipe is designed to round tube, to guarantee to have enough inflows.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of vacuum heat collection pipe;
Fig. 3 is the cross-sectional structure schematic diagram of vacuum heat collection pipe.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
The specific embodiment
Embodiment.As shown in Figure 1, comprise attemperater 1, vacuum heat collection pipe 2, cold pipe 3 and moisturizing passage 4.Vacuum heat collection pipe 2 be shaped as oblate (see figure 3), the straight-through not back cover (see figure 2) of pipe in it, the interlayer between interior pipe and the outer tube is evacuated.Cold pipe 3 is exactly the vacuum tube that does not plate heat-sink shell, and its profile is designed to circle, and to guarantee that enough water inlets are arranged, the configuration quantity of cold pipe 3 according to the requirement of rate of water make-up, is provided with by a certain percentage with vacuum heat collection pipe 2.Moisturizing passage 4 is arranged in the good heat-insulation layer, with antifreeze.The upper end of vacuum heat collection pipe 2 connects attemperater 1, is communicated with attemperater 1; The lower end of vacuum heat collection pipe 2 connects moisturizing passage 4, is communicated with moisturizing passage 4; The upper end of cold pipe 3 connects attemperater 1, is communicated with attemperater 1, and the lower end of cold pipe 3 connects moisturizing passage 4, is communicated with moisturizing passage 4.
Operation principle: when no solar light irradiation when (night), system is in balance static state.When solar light irradiation vacuum heat collection pipe 2, luminous energy is converted into heat energy the water in the vacuum heat collection pipe 2 is heated, and hot water upwards floats and flows into attemperater 1.When hot water upwards floats, produce negative pressure in moisturizing passage 4, the cold water in the attemperater 1 flows into cold pipe 3 and carries out moisturizing, to reach balance.Under the sunshine Continuous irradiation, the cold water that flows in the vacuum heat collection pipe 2 is continued heating, hot water flows out continuously, and cold water constantly flows into and carries out moisturizing, and flowing of hot water still do not leaned on the buoyancy of self at this moment, and cold water also can produce certain motive force to hot water flow in the moisturizing process, hot and cold water is taken their own roads, thereby forms an orderly hot and cold water circulatory system, and the vacuum heat collection pipe 2 of this moment became water heater, the heat energy that vacuum heat collection pipe 2 is produced is fully utilized.
Embodiment of the present utility model is not limited to the foregoing description, all belongs within the protection domain of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
