Description

Technical Field

[0001] The utility model belongs to the field of energy conservation and environmental protection, and particularly relates to a double-storage hot water tank. Background Art

[0002] As one of the most promising renewable energy sources, solar energy has been widely utilized in China in recent years. However, due to the large influence of solar energy by random factors such as day and night, seasons, and weather, the stability and reliability of solar heating systems are poor, and auxiliary heat sources or heat storage devices need to be added. Currently, the research mainly focuses on solar-air source heat pump composite systems and solar-absorption unit composite systems. In addition, there are also solar-geothermal energy systems.

[0003] Domestic research on solar energy + geothermal energy focuses on solar energy and soil seasonal heat storage for heating domestic hot water, or heat storage in the transitional season for winter heating, lacking research on long-term heat storage and heating in hot summer and cold winter regions.

[0004] In the existing solar thermal + ground source heat pump system, the intermediate hot water storage tank has always been in a state where it can be used or not, and can be used in large or small amounts. Using the intermediate hot water storage tank is also a hot water storage tank. There is no structure inside the tank, and it is filled with water as a whole. The temperature of the water in the tank is not evenly distributed, and the temperature stratification can reach more than 10°C; the whole tank heats up and cools down as a whole, with low utilization rate; after the whole tank heats up, the overall temperature is high, and the heat dissipation is large, etc. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a double-storage hot water tank, which changes the original structure to solve the above problems.

[0006] In order to solve the above problems existing in the prior art, the technical solution adopted by the utility model is as follows:

[0007] The double-storage hot water tank includes two hot water storage tanks, which are arranged longitudinally. Horizontally connected with multiple partitions inside the hot water storage tanks, and the multiple partitions divide the interior of the hot water storage tanks into multiple channels. The two hot water storage tanks are connected by two connecting pipes.

[0008] By setting two hot water storage tanks and connecting them through connecting pipes, since hot water will rise and cold water will sink, the cold water and hot water can be stored separately using the two hot water storage tanks. Even if the cold water at the lower part has not been fully heated, the hot water at the upper layer can still be used.

[0009] Further, the hot water storage tank includes a first hot water storage tank and a second hot water storage tank. The first hot water storage tank is disposed above the second hot water storage tank. The first hot water storage tank includes a top channel, a middle channel, and a bottom channel from top to bottom. The second hot water storage tank includes a top channel, a middle channel, and a bottom channel from top to bottom. The top channel of the first hot water storage tank is communicated with the bottom channel of the second hot water storage tank through a connecting pipe, and the bottom channel of the first hot water storage tank is communicated with the top channel of the second hot water storage tank through a connecting pipe.

[0010] To ensure the separation of cold water and hot water, on the one hand, two water tanks need to be ensured, and on the other hand, the water in the two water tanks needs to be able to flow through each other, so that the cold water and hot water can be effectively separated. For this reason, multiple channels are provided inside the hot water storage tank to allow the water flow to flow in a predetermined direction, facilitating the separation of cold water and hot water.

[0011] Further, the hot water storage tank includes a first hot water storage tank and a second hot water storage tank. A first partition, a second partition, and a third partition are connected inside both the first hot water storage tank and the second hot water storage tank. A first channel is between the first partition and the top of the hot water storage tank, a second channel is between the first partition and the second partition, a third channel is between the second partition and the third partition, and a fourth channel is between the third partition and the bottom of the hot water storage tank. The connecting pipe includes a first connecting pipe and a second connecting pipe. Two ends of the first connecting pipe are respectively communicated with the fourth channel of the first hot water storage tank and the first channel of the second hot water storage tank, and two ends of the second connecting pipe are respectively communicated with the first channel of the first hot water storage tank and the fourth channel of the second hot water storage tank.

[0012] Further, the first channel, the second channel, the third channel, and the fourth channel are communicated end to end to form a one-way flow channel. The first partition and the third partition are connected to one end of the hot water storage tank, the second partition is connected to the other end of the water tank, and the second partition is disposed between the first partition and the third partition.

[0013] Further, an exhaust pipe is communicated with the hot water storage tank.

[0014] Further, the hot water storage tank is of a rectangular structure. The hot water storage tank includes a protective layer, a heat insulation layer, and an inner liner layer from outside to inside. The heat insulation layer is made of rock wool, and the protective layer is made of stainless steel. By providing a multi-layer structure for the hot water storage tank, it has good heat insulation and good protection, making the hot water storage tank not easily break.

[0015] Further, the hot water storage tank includes an outer shell and an inner liner disposed inside the outer shell. A vacuum chamber is provided between the outer shell and the inner liner, and the inner liner is connected to the outer shell through a plurality of support blocks.

[0016] The support block is in a triangular pyramid structure. There can be various structures for the heat preservation of the hot water storage tank. Most traditional hot water storage tanks achieve heat preservation through heat preservation structures, while this solution achieves heat preservation through vacuum, which has a better heat preservation effect. In addition, the inner tank is supported by the support block in a triangular pyramid structure, minimizing the contact area between the inner tank and the outer shell as much as possible to improve the heat preservation effect.

[0017] Furthermore, an arc-shaped flow channel is provided inside the inner tank, and the arc-shaped flow channel is arranged at the connection of the two channels. By setting the arc-shaped flow channel, the water flow becomes smoother, the occurrence of eddy currents is reduced, and the heat exchange efficiency between cold water and hot water is improved.

[0018] Furthermore, the connecting pipe is connected to the outer shell through an end sealing structure, and the end sealing structure includes a sleeve, a cover plate, and a telescopic pipe;

[0019] The cover plate is bolted to the outer shell, and a third sealing ring is provided between the cover plate and the outer shell;

[0020] The sleeve is arranged between the outer shell and the cover plate, and a first sealing ring is provided between the sleeve and the cover plate;

[0021] The connecting pipe passes through the cover plate and is connected to the telescopic pipe, the telescopic pipe is connected to the inner tank, and a second sealing ring is provided between the connecting pipe and the cover plate.

[0022] Due to the adoption of the vacuum structure, it is necessary to ensure the vacuum between the outer shell and the inner tank to prevent gas from entering, and at the same time, ensure that the contact area is as small as possible to reduce heat dissipation. The inner tank can be connected to the connecting pipe through the telescopic pipe. Since the telescopic pipe is located in the vacuum chamber, there is no need to consider the problem of its heat dissipation. The connection between the connecting pipe and the outer shell adopts the structure of the cover plate and the sleeve, which are connected by using the cover plate and the sleeve, and then sealed with a sealing ring to ensure the vacuum environment.

[0023] The beneficial effects of the present utility model:

[0024] 1. By providing two hot water storage tanks and arranging them vertically, the hot water can be concentrated in the upper hot water storage tank and the cold water can be concentrated in the lower hot water storage tank, so that it is not necessary to heat all the water in the hot water storage tank before use.

[0025] 2. Through the improvement of the structure of the hot water storage tank, the present utility model has a better heat preservation effect and can prevent heat loss. BRIEF DESCRIPTION OF THE DRAWINGS }1]]]}
