Description

A solar water heater that can be used as a balcony guardrail

technical field

The invention relates to a water heater, in particular to a solar water heater which can be used as a balcony guardrail.

Background technique

With the depletion of human natural resources and the maturity of solar energy technology, it has become a trend to vigorously promote the integration of solar thermal utilization technology into the design of building structures. Taking solar thermal utilization into consideration at the beginning of architectural design: this is what we call Combination of solar energy and buildings. However, in the process of China's rapid economic development, the scale of urbanization is getting bigger and bigger, and the urban population has increased accordingly. Therefore, high-rise residential buildings in the city also stand like a forest. If the original household solar water heater or collective project solar water heating system is adopted, there will be a problem, that is, the installation area is too small to meet the total water demand of the building. For high-rise buildings with a small footprint and a large number of residents. Solar water heaters have also made corresponding innovations, using the current split technology of solar water heaters, designing roofs and external walls with solar vacuum tubes as components for hot water supply, that is: research and development of split hot water systems and putting them on the market. Among them, the most popular one is the split balcony solar water heating system. The heat collecting part of the split-type balcony solar water heating system can be fixed on the south-facing balcony railing or the south facade wall, and the water tank is placed on the inner wall of the house. There are two main modes of operation: one is the working mode of thermosiphon natural circulation, and the other is the working mode of forced circulation. Both of these two methods use medium circulation, vacuum tubes, built-in metal heat pipes, and pipe threads to the heat collector header, and then connect the heat collector header and the heat storage tank with pipes to form a hot water system. Such a structure has the disadvantages that installation and maintenance are cumbersome, and the cost of housing supporting facilities is relatively high.

Detailed ways

As shown in Figure 1, Figure 2, and Figure 3, a solar water heater that can be used as a balcony guardrail includes a water storage mechanism, a heat collection mechanism, and a fixed bracket. The heat collection mechanism is composed of multiple spaced heat collection units, and the water storage mechanism It is an elongated pressurized water tank 6 used as a guardrail slab connected to the building columns 1 at both ends, and the heat collecting mechanism located between the two building columns 1 is located below the pressure-bearing water tank 6 as a guardrail railing and fixing brackets.

The pressurized water tank 6 has an outer shell 15, an inner tank 16 and an insulating layer 17 between the inner tank 16 of the outer shell 15. The material of the outer shell 15 can be a galvanized silicon plate, and the cross-sectional shape of the outer shell 15 can be square or circular. The material of inner container 16 is stainless steel, and the diameter of inner container 16 can be 10～25 centimetres, and the centerline of pressurized water tank is horizontal state, and the two ends of pressurized water tank 6 have the water inlet 10 that is connected to cold water system and communicate with shower respectively. The water outlet 2 of the system, one end of the water outlet 2 has an exhaust valve 3, a sensor 4 and an electric heating socket 5, and accessories such as instruments can also be selected.

Each heat collecting unit of the heat collecting mechanism is composed of a heat pipe 7 whose upper end extends into the inner tank 16 of the pressurized water tank 6, and a vacuum tube 9 built into the heat pipe 7. The top of the heat pipe 7 has an external thread matched with the pressurized water tank 6 to collect heat. The number of vacuum tubes 9 in the unit is 20-50.

The fixed support includes three vertical braces 12, cross braces 11 at the tops of the three vertical braces 12, and tailstock seats 13 at the bottom of the three vertical braces 12. The upper end of 12 is fixed with cross brace 11 by connector 8, and the lower end of three upright braces 12 is fixed on the balcony ground by anchor bolts. The butt stock 14 of a plurality of plastic materials is installed on the butt stock seat 13, and the lower end of each vacuum tube 9 stretches in the butt stock 14 below it.

The solar water heater that can be used as balcony guardrail of the present invention is installed on the sunny balcony of the house, the pressurized water tank is used as the railing of the balcony guardrail, and the fixed bracket and the vacuum tube are used as the railing of the balcony guardrail. Therefore, in terms of supporting facilities of the house, the present invention can be used The solar water heater used as the balcony guardrail is used as the guardrail of the sunny balcony of the house, and the water inlet of the pressurized water tank is connected to the cold water system, and the water outlet of the pressurized water tank is connected to the shower system. This not only reduces the number of balcony guardrails, that is, reduces the cost of supporting facilities in the house, but also facilitates installation and maintenance, no longer requires workers and masters to perform dangerous operations on heights, and the space in the balcony is not reduced at all. The solar water heater that can be used as a balcony guardrail can be matched with the present invention, which greatly improves the utilization rate of solar energy in families, relieves the shortage of electricity in cities, and saves household electricity expenses at the same time. The present invention can be used as the solar water heater of balcony guardrail and also has the following advantages: 1) does not need to be placed on the cumbersome process of fixing the solar water heater on the roof, compared with the solar water heater of split structure, the solar water heater of existing split structure adopts The two water tanks, the heat collector header and the hot water storage tank, use two heat exchange processes, that is, the vacuum tube heats the water in the heat collector header, and the water in the heat collector header is exchanged with the water in the hot water storage tank. In order to increase the temperature of the water in the hot water storage tank, such multiple heat exchanges will not only cause the loss of heat in vain, but also increase the cost of the entire hot water system. The primary heat exchange process is reduced, a water tank and secondary heat exchange components are reduced, the cost is greatly reduced, and the thermal efficiency can be increased by about 20%. 2) The solar water heater is integrated with the building, avoiding the phenomenon that the original solar water heater is visually unattractive and incongruous with the house.

The solar water heater that can be used as a balcony guardrail in the present invention is not limited to the above-mentioned structure. In order to protect the vacuum tubes, an upright bar can be provided on the inner side of each vacuum tube close to the balcony. In order to increase the utilization rate of sunlight, the cross-section of the above-mentioned vertical bar is arc-shaped, and the side of the bar facing the vacuum tube is a reflective surface. The present invention can also make other deformations, as long as the pressurized water tank is used as the guardrail railing, and then other structures are used as the guardrail railing, all belong to the protection scope of the present invention.
