Abstract
The utility model relates to a circulating solar water heater, comprising an upper water storage tank, a heat exchange tube and a lower sink, wherein the heat exchange tube is connected to the bottom wall of the upper water storage tank, the lower sink is arranged at the lower end of the heat exchange tube, the two ends of the heat exchange tube are in a run-through mode, the heat exchange tube communicates the upper water storage tank with the lower sink, the bottom wall of the middle of the upper water storage tank is connected with a circulating water pipe, and the other end of the circulating water pipe is communicated with the middle of the lower sink. According to the circulating solar water heater, the water circulation speed is high, the heat exchange efficiency is high, the water heating speed is high, and the solar resources are sufficiently utilized. The circulating solar water heater has a simple structure, low manufacturing cost and high heating efficiency.
Description
Technical field
The utility model relates to a kind of loop solar water heater.
Background technology
China has had the history of two, 30 years since coming out from initial solar water heater so far, through the whole journey, say that from technological layer its technique and structure do not have new improvement, or several large old patterns, comprise the compositions such as storage tank, ampuliform heat exchanger tube, support, subiculum support and another accessory, ampuliform heat exchanger tube upper end is connected with upper storage tank, ampuliform heat exchanger tube lower end closed, its weak point is exactly: 1. ampuliform heat exchanger tube, and water becomes inactive state inside; 2. circulate faint, rate of heat exchange is low, and water heating speed is too slow, and waste has the period of solar irradiation.
Summary of the invention
The utility model is low for above-mentioned prior art rate of heat exchange, and the problem that water heating speed is too slow provides a kind of loop solar water heater, and its rate of heat exchange is high, and firing rate is fast.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of loop solar water heater, it comprises storage tank, is connected to the heat exchanger tube on the storage tank diapire, described heat exchanger tube lower end is provided with lower flume, the heat exchanger tube two ends are penetrating, heat exchanger tube is communicated with upper storage tank and lower flume, be connected with circulating water pipe on the diapire of described upper storage tank middle part, be communicated with in the middle part of the circulating water pipe other end and lower flume.
Described circulating water pipe periphery is provided with heat-insulation layer.
The utility model is provided with lower flume in the heat exchanger tube lower end, heat exchanger tube is communicated with storage tank and lower flume, and is provided with circulating water pipe between upper storage tank and lower flume, and the hot water of heat exchanger tube the inside rises to storage tank top, the water at low temperature of upper storage tank bottom enters lower flume by circulating water pipe, the water of lower flume enters heat exchanger tube and heats, so circulation, feedwater heating, water circulating speed is fast, rate of heat exchange is high, and water heating speed is fast, takes full advantage of solar energy resources.The utility model is simple in structure, low cost of manufacture, and heating efficiency is high.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of loop solar water heater, it comprises storage tank 1, is connected to the heat exchanger tube 2 on storage tank 1 diapire, heat exchanger tube 2 lower ends are provided with lower flume 3, and heat exchanger tube 2 two ends are penetrating, and heat exchanger tube 2 is communicated with upper storage tank 1 and lower flume 3, be connected with circulating water pipe 4 on upper storage tank 1 middle part diapire, circulating water pipe 4 other ends are communicated with lower flume 3 middle parts, and circulating water pipe 4 peripheries are provided with heat-insulation layer 5, are provided with exhaust overflow pipe 6 on upper storage tank 1 sidewall.
when the utility model specifically uses, at first the water inlet 7 of going up on storage tank 1 connects the water source, by the water inlet 7 interior notes water at low temperature of storage tank 1 up, part water enters heat exchanger tube 2 and lower flume 3, when the sun impinges upon on heat exchanger tube 2, heat exchanger tube 2 absorbs solar energy with the heating of the water in heat exchanger tube 2, after water heat absorption in heat exchanger tube 2, temperature raises, proportion reduces and rises, form a power that makes progress, thereby enter in storage tank 1, and on move on to storage tank 1 top, the lower water of temperature in upper storage tank 1 enters into lower flume 3 by circulating water pipe 4, water in lower flume 3 enters heat exchanger tube 2 and heats, move on in storage tank 1 on after the water heating, so circulation, realize that constantly circulation is heated water, reach the purpose of quick water heating.The utility model is simple in structure, and low cost of manufacture is safe and convenient to use, and heating efficiency is high.
Claims (2)
1. loop solar water heater, it comprises storage tank, is connected to the heat exchanger tube on the storage tank diapire, it is characterized in that: described heat exchanger tube lower end is provided with lower flume, the heat exchanger tube two ends are penetrating, heat exchanger tube is communicated with upper storage tank and lower flume, be connected with circulating water pipe on the diapire of described upper storage tank middle part, be communicated with in the middle part of the circulating water pipe other end and lower flume.
