Description

Wall embedded solar water heating system

technical field

The utility model mainly relates to the integration of solar water heaters and buildings, which expands the area of effective solar radiation without affecting the beauty of the building, and is of great significance for alleviating the energy consumption of domestic hot water in our country.

Background technique

The energy consumption of domestic hot water accounts for about 30% of the total energy consumption of buildings. The use of solar energy, a clean and renewable energy source, for domestic hot water is of great significance to my country's energy strategy. Most of the solar water heaters currently on the market are installed on building roofs, which cannot meet the needs of uniquely shaped buildings and affect the overall appearance of the building.

Contents of the invention

The utility model mainly provides a path and a device for integrating solar water heaters and buildings for residential buildings with small roof use area, high building density and high demand for domestic hot water in my country. The device can efficiently utilize solar energy to supply domestic hot water, has low energy consumption and no pollution.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A wall-embedded solar water heating system, characterized in that it includes a wall, a solar heat pipe vacuum tube, a header and a hot water storage tank, the outer surface of the wall is provided with a depression, and the outside of the depression is provided with a There is a glass, the vacuum tube of the solar heat pipe is arranged in the depression, the vacuum tube of the solar heat pipe is connected to the header tank, and the hot water storage tank is connected to the header tank through a hot water return pipe. header connection.

A metal heat absorbing plate is arranged in the vacuum tube of the solar heat pipe, and the angle of the metal heat absorbing plate is perpendicular to the direction of the maximum value of the solar radiation intensity.

In order to simplify the installation and factory processing of the system of the utility model, the utility model also includes a wall-embedded solar water heating system including a sealed shell with a light-transmitting plate arranged in the depression, and the solar heat pipe vacuum tube and the header are arranged in the sealed housing. By arranging the solar heat pipe vacuum tube and header in the sealed casing, it can be directly processed and formed in the factory, and then directly packaged in the wall on site.

Compared with the prior art, the hot water system of the utility model integrates the solar energy and the wall, designs a depression on the wall and forms a sealed heat-preservation and heat-absorbing chamber with glass, and seals the vacuum tube of the solar heat pipe in the heat-preservation and heat-absorbing chamber Compared with the solar water heater on the roof, it not only overcomes the disadvantages of occupying the roof area, but also makes the use of solar energy not limited by the space position. All the heat can be utilized, which improves the utilization rate of solar energy. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail:

As shown in FIG. 1 , the wall-embedded solar water heating system of the present invention is the same as the window 11 , and is arranged on the facade of the building wall 12 .

The hot water system of the utility model utilizes the sunken side wall of the building, installs the solar heat pipe vacuum tube 1, see Fig. 2, adopts the header box 9 to connect the solar heat pipe vacuum tube to the hot water supply and return pipe 4, and sends it to the kitchen or bathroom for heat storage Water tank 2, gas or electric auxiliary heater 7 provide residents' domestic water.

A metal heat absorbing plate 8 is added in the vacuum tube of the solar heat pipe, as shown in FIG. 3 . And the angle of the metal heat absorbing plate is perpendicular to the direction of the maximum value of the solar radiation intensity.

The sun shines on the surface of the vacuum tube 1 of the solar heat pipe, the metal heat absorbing plate 8 absorbs heat and transfers it to the medium in the heat pipe, the medium evaporates to the condensation end (header) to release heat, and heats the cold water supply pipe 5 in the header 9 Provided cold water, when the temperature control device measures that the high temperature water meets the set temperature requirements, the hot water is delivered to the hot water storage tank 2 for heat storage. The utility model needs to be combined with the building, and the solar hot water collector is embedded in the recessed wall, and the position of the return water main pipe is reserved to maintain the beauty of the building. At the same time, local damage to the vacuum tube of the heat pipe does not affect the operation of the entire hot water system, which is safe and reliable. The space where the heat collector is located is a closed space surrounded by walls and glass. After absorbing solar radiation, it has a certain heat storage performance and reduces the heat transfer loss between the heat collector and the surrounding space.
