Description

A kind of double liner solar water heater water tank

technical field

The utility model relates to the technical field of solar energy, in particular to a double-inner solar water heater water tank structure.

Background technique

At present, the commonly used solar water heater has only one inner tank, and the capacity of the inner tank is designed according to the heat collector heating the normal temperature water to the bathing temperature after the sun shines on a sunny day, so there are the following problems: 1. The higher temperature cannot be obtained earlier on sunny days Hot water is inconvenient to use; 2. Frequent heating of a whole tank of water requires high operating costs: currently commonly used solar water heaters, in weather with insufficient sunlight, when the water temperature of the entire water tank does not reach the bathing temperature, the electric heater installed in the water tank Automatic heating, heating to the set bathing temperature for use at night, if the hot water consumption is less than the water tank capacity of the water heater, the excess hot water will be wasted, and the operating cost will be higher.

Contents of the invention

The utility model provides a double-inner solar water heater water tank, and the utility model solves the problems that the existing solar water heater sometimes has redundant hot water wasted in vain and the operating cost is high.

In order to solve the above-mentioned problems, the utility model adopts the following technical scheme: a double-inner solar water heater water tank, an upper inner tank 3 and a lower inner tank 4 are vertically arranged in the heat preservation shell 1 of the water tank, and the upper inner tank 3 and the lower inner tank are vertically arranged. 4 communicate with each other through the short tube 8 and the second short tube 11; the thermal insulation shell 1 and the lower inner tank 4 and the upper inner tank 3 are filled with thermal insulation material 2; The upper circulation pipe interface 6 and the hot water outlet interface 9, the bottom area of the upper liner 3 has a nozzle 10 for installing auxiliary electric heating, and the bottom of the lower liner 4 has an interface 5 connected with the inlet of the solar collector and connected with the water tank. The connected lower circulation inlet pipe interface 7.

The volume of the upper liner 3 is less than or equal to the volume of the lower liner 4 .

The utility model relates to a double-liner solar water heater water tank, no matter whether the solar water heater is equipped with a full glass vacuum tube collector or a flat solar collector, it can be used at any time 365 days a year according to the intensity of sunlight radiation. According to the changing natural law, a brand-new solar water heater water tank is designed to obtain hot water at a bathing temperature in a short period of time under the condition of natural sunshine throughout the year.

In the utility model, the hot water storage tank of the solar water heater is designed as two vertically arranged inner tanks, and the volume of the upper inner tank is less than the volume of the lower inner tank. A hot water outlet is provided, and the bottom of the upper inner tank is connected with the top of the lower inner tank through a communication pipe.

Beneficial effects of the present invention: the present invention makes full use of the natural law of fluctuations in the intensity of solar radiation to heat water step by step, and continuously obtains hot water suitable for bathing, so as to meet the demand for hot water without using auxiliary electric heating as much as possible, Or reduce the use time and frequency of auxiliary electric heating, make solar water heaters more humane, and save energy more significantly.

Explanation of symbols in the figure: thermal insulation shell 1, thermal insulation material 2, upper inner tank 3, lower inner tank 4, connection 5, upper circulation pipe connection 6, lower circulation inlet pipe connection 7, short pipe 8, hot water outlet connection 9, pipe Port 10, second short pipe 11.

Detailed ways

As shown in Figure 1, a double-liner solar water heater water tank, an upper inner tank 3 and a lower inner tank 4 are vertically arranged in the thermal insulation shell 1 of the water tank, and a short tube 8 is passed between the upper inner tank 3 and the lower inner tank 4 It communicates with the second short pipe 11; the thermal insulation shell 1, the lower inner tank 4 and the upper inner tank 3 are filled with thermal insulation material 2; the upper inner tank 3 is provided with an upper circulation pipe interface 6 connected to the outlet of the heat collector and a thermal The water outlet interface 9, the bottom area of the upper liner 3 is provided with a nozzle 10 for installing auxiliary electric heating, the bottom of the lower liner 4 is provided with an interface 5 connected to the inlet of the solar collector and a lower circulation inlet pipe interface connected to the water tank 7.

The volume of the upper liner 3 is less than or equal to the volume of the lower liner 4 .

5 of the solar water heater water tank is connected to the water inlet of the heat collector, the upper liner 3 is connected to the water outlet of the heat collector, the lower circulation inlet pipe interface 7 of the lower liner 4 is connected to tap water, and a safety valve with a check valve is installed at the same time. Hot water outlet interface 9 installs hot water pipe and valve. When the water heater is running, the two inner tanks in the water tank are full of water. When the sun rises in the morning, after the collector absorbs solar radiation, the water in the collector circulates naturally through the phenomenon of "thermosiphon" or passes through the outlet of the collector. The temperature difference of the water at the bottom of the tank starts the forced circulation of the circulation pump, and presses the hot water from the collector to the top area of the upper inner tank, and the cold water at the bottom of the upper inner tank enters the top of the lower inner tank, and with the sun As the radiation continues, the water in the top area of the upper inner tank quickly reaches the temperature for bathing, and the valve can be opened to bathe. With the extension of solar radiation, the water at the bottom of the upper inner tank and the top of the water inlet tank also rapidly Heat up until the water at the bottom of the lower liner also reaches a higher temperature. From the top to the bottom of the upper inner tank 3 to the top and bottom of the lower inner tank 4, the temperature of the hot water forms a gradient distribution from high to low. The hot water is the hot water with the highest temperature generated by the operation of the water heater, and there will be no mixing of cold water and hot water, which improves the utilization rate of the hot water. Even in the weather with weak sunlight, the solar water heater water tank of the present invention can also obtain a certain amount of hot water. If the amount of hot water is small, there is no need to start auxiliary electric heating. Electric heating starts, how much is used to compensate, not only greatly shortens the auxiliary heating time, but also saves a lot of electricity costs that solar water heaters usually consume to heat a whole tank of water when the weather is bad, so that the solar energy can really be used to the greatest extent. , The utility model has made a brand-new technical reform to the solar water heater.

Finally, it should be noted that obviously, the above-mentioned embodiments are only examples for clearly illustrating the utility model, rather than limiting the implementation manner. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the protection scope of the present utility model.
